Get Driver assistance systems Guide for Volkswagen Golf 4 Door Seventh Generation (2017-2020)

The Hill Start Assist feature cannot hold the vehicle in all hill start situations (for example, if the surface is icy or slippery).

Hill Start Assist can only help keep the vehicle from moving for less than 2 seconds. After that, the brakes will be released and the vehicle can roll down the

hill.

Downhill speed control

The downhill speed control feature in vehicles with DSG ^®automated transmission help to support braking when driving downhill ⇒ ꢀ. The system uses the

braking power of the engine.

The DSG selects the best gear for the circumstances, depending on the downhill slope and the current speed. The selector lever must be in position

D/S⇒ Automatic transmission selector leverꢀ. Downhill speed control is not active in Tiptronic mode ⇒ Shifting with Tiptronic^®ꢀ.

The downhill speed control feature can shift down only as far as third gear, so it may be necessary to activate the Tiptronic mode when driving down very steep hills

When in Tiptronic mode, select second or ﬁrst gear manually to use the braking power of the engine and relieve the load on the brakes.

Downhill speed control activates automatically if all of the following conditions apply:

The downhill slope is greater than about 6%.

AND: The selector lever is in position D/S.

AND (when the cruise control or Adaptive Cruise Control (ACC) is switched off): The vehicle speed is less than about 50 mph (80 km/h) or the brake

pedal is depressed.

AND (when the cruise control or Adaptive Cruise Control (ACC) is active): The stored speed is exceeded.

Downhill speed control deactivates automatically if one of the following occurs:

The downhill slope is less than about 6%.

OR: The DSG shifts up to a higher gear because the engine speed is faster than about 4,500 rpm.

OR (when the cruise control or Adaptive Cruise Control (ACC) is active): The stored speed can be maintained.

WARNING

The intelligent technology of the downhill speed control feature cannot overcome the laws of physics and system-related limits. Never let the increased

convenience provided by the downhill speed control feature tempt you into taking risks.

Always adjust your speed, driving style, and the distance you keep between you and the vehicles ahead of you to the road, traffic, weather, and visibility

conditions.

Unintended vehicle movement can cause serious personal injury.

The downhill speed control feature is not a substitute for careful and attentive driving.

The downhill speed control feature cannot slow the vehicle down in all situations (for example, if the ground is slippery or icy).

Always be prepared to take full control of the vehicle at all times.

WARNING

Always be ready to apply the brakes. Otherwise accidents and injuries can occur.

The downhill speed control feature is merely a driving aid and cannot always slow the vehicle down enough on all downhill grades.

The vehicle may pick up speed even though the downhill speed control feature is active.

WARNING

Driving with too little fuel in the fuel tank increases the risk of stalling, especially when driving up and down hills.

If your vehicle stalls suddenly, this can cause an accident and serious personal injuries.

Driver assistance and braking assistance systems can malfunction when there is too little fuel in the tank and cause you to lose control of the vehicle.

Never drive until the fuel tank is almost empty.

Cruise control

Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Display and indicator lightsꢀ

175

⇒ Cruise control operationꢀ

Your vehicle may be equipped with cruise control, which helps maintain an individually stored constant speed when driving above about 15 mph (20 km/h).

Cruise control slows down the vehicle only by reducing the ﬂow of fuel to the engine, not by braking

⇒

ꢀ.

WARNING

Using the cruise control when it is not possible to drive safely at a constant speed can be dangerous and can lead to an accident and serious personal injuries.

Never use cruise control when driving in heavy or varying traffic or when you cannot keep a safe distance between you and the vehicles ahead of you.

Never use cruise control on steep, winding, or slippery roads (such gravel roads, wet roads, or snowy or icy roads) or on roads with standing water.

Never use cruise control when driving off-road or on unpaved roads.

Always adjust your speed and the distance you keep between you and the vehicles ahead of you to the road, traffic, weather, and visibility conditions.

To help prevent unintended operation of cruise control, switch the system off when it is not being used.

It is dangerous to use the Resume feature when the previously set speed is too high for the existing road, traffic, or weather conditions.

When going downhill, the cruise control may not be able to maintain a constant speed. The vehicle will speed up because of its own weight. Downshift

and/or use the foot brake to slow the vehicle.

Adaptive Cruise Control (ACC)

Applicable only in the United States

Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Display, warning and indicator lightsꢀ

⇒ Radar sensorꢀ

⇒ Using ACCꢀ

⇒ When to temporarily switch off ACC ꢀ

⇒ Special driving situationsꢀ

Your vehicle may be equipped with the Adaptive Cruise Control system (ACC), which helps maintain an individually stored constant speed between about 20 mph

(30 km/h) and 95 mph (150 km/h) and a previously set distance in time intervals between your vehicle and those in front of you.

The vehicle may be braked, if the situation so requires, to a standstill by an active braking maneuver⇒ ꢀ.

Driver intervention warning

Adaptive Cruise Control has system-speciﬁed limits. As a driver, you must control the speed and the distance to other vehicles under some circumstances. If that is

necessary, the system requests the driver to take over using a visual and audible warning , even if the vehicle can be braked to a standstill by an active braking

maneuver.

WARNING

Always remember that the Adaptive Cruise Control has limits – Using Adaptive Cruise Control when it is not possible to drive safely at a constant speed can

be dangerous and can lead to an accident and serious personal injury.

Adaptive Cruise Control will not slow the vehicle down or maintain the set distance when you drive towards an obstacle or something on or near the road

that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle.

Always adjust your speed and the distance you keep between you and the vehicles ahead of you to the road, traffic, weather, and visibility conditions.

Never use Adaptive Cruise Control on steep, winding, or slippery roads (such gravel roads, wet roads, or snowy or icy roads) or on roads with standing

water.

178

Never use Adaptive Cruise Control when driving in heavy or varying stop-and-go traffic.

Never use Adaptive Cruise Control when driving off-road or on unpaved roads.

Always remember that the Adaptive Cruise Control cannot detect a vehicle that is driving towards you in your traffic lane and that it cannot detect narrow

vehicles such as motorcycles and bicycles.

Never follow a vehicle so closely that you cannot stop your vehicle safely. The Adaptive Cruise Control cannot slow or brake the vehicle safely when you

follow another vehicle too closely. Always remember that the Adaptive Cruise Control has a braking power that is only about 30% of the vehicle's maximum

braking ability, under certain circumstances the automatic braking function cannot bring the vehicle to a stop in time.

Always turn off Adaptive Cruise Control when entering turn lanes, exit lanes and construction zones or in similar situations because the vehicle will

automatically accelerate to the stored speed when the road ahead is clear.

To help prevent unintended operation of Adaptive Cruise Control, switch the system off when it is not being used.

It is dangerous to use the Resume feature when the previously set speed is too high for the existing road, traffic, or weather conditions.

When traveling downhill, the Adaptive Cruise Control may not be able to maintain a constant speed. The vehicle will speed up because of its own weight.

Downshift and/or use the foot brake to slow the vehicle.

Never allow the closing speed between you and other vehicles to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If

closing speed is too high, you must apply the brakes yourself to reduce the risk of a rear-end crash.

If a driver intervention warning or Front Assist warning appears in the instrument cluster display, immediately take over the control of the brake and gas

pedals and slow down the vehicle or bring it to stop when necessary and according to the traffic situation.

Always be prepared to take over the control of the brake and the gas pedal in every situation.

NOTE

If you suspect that ACC doesn't work properly or the sensors are damaged, switch off ACC immediately.

See an authorized Volkswagen dealer or Volkswagen Service Facility for assistance and have the ACC system checked.

The ACC restricts the vehicle speed to 95 mph (150 km/h).

If the ACC is active, you may hear noise during the automatic braking procedure. This is normal; the noises are caused by the braking system.

Certain settings can be saved in the personalized user profiles ⇒ Personalized user profilesꢀ.

180

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Vehicles equipped with ACC have a radar sensor behind the Volkswagen emblem to monitor the trafﬁc situation ⇒ Fig. 127Ⓐꢀ. The sensor can detect moving

vehicles up to about 130 yards (120 m) in front of your vehicle.

The radar sensor function can be impaired by things such as mud, slush, or snow, or by conditions such as heavy rain or spray. In cases like these, the ACC may

not work. The driver message ACC not available appears in the instrument cluster display. Clean the radar sensor as required

⇒

ꢀ.

The ACC will automatically be available again as soon as the radar sensor is no longer impaired. The message in the instrument cluster display turns off.

The area in front of and around the radar sensor ⇒ Fig. 127Ⓑꢀ must not be covered by objects such as stickers, additional headlights, non-standard license plate

brackets, or other things, as these items can impair the function of the ACC system.

Any structural modiﬁcations to the vehicle, for example, lowering the vehicle or alterations to the front end trim, can impair the function of the ACC system. Structura

modiﬁcations should only be carried out by a qualiﬁed workshop ⇒ Parts, accessories, repairs, and modiﬁcationsꢀ. Contact an authorized Volkswagen dealer or an

authorized Volkswagen Service Facility for assistance.

The Volkswagen emblem affects the function of the radar sensor. Use the original Volkswagen emblem only.

Incorrectly performed repairs to the front end of the vehicle can change the position of the radar sensor and therefore impair the function of the ACC system. Repair

work should only be carried out by a qualiﬁed workshop. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for assistance.

NOTE

If you notice that the Adaptive Cruise Control (ACC) or Front Assist doesn't work properly, or if you suspect that the radar sensor has been damaged or if its

position has been changed, switch off ACC immediately. This can help prevent further damage. Contact an authorized Volkswagen dealer or an authorized

Volkswagen Service Facility to have the radar sensor realigned.

The radar sensor can become misaligned if it is hit, for example, when parking the vehicle. Readjusting the sensor could impair the performance of the

system or cause it to switch off.

Repairs to the radar sensor require special knowledge and tools. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility

for assistance.

Remove snow with a brush, and remove ice with a solvent-free deicer spray.

The following conditions could prevent the ACC from reacting, or delay its ability to react:

When driving in tight curves.

When the accelerator pedal is depressed.

When Front Assist is switched off or if there is a fault.

When no gear is selected.

When the ESC is taking corrective action.

When the driver safety belt is not buckled.

When several brake lights on the vehicle or trailer are faulty.

When the radar sensor is dirty or covered.

When the vehicle is in Reverse (R).

When weather conditions are poor.

When narrow vehicles, such as motorcycles, are moving in front of your vehicle.

When vehicles are traveling slightly offset to the left or right in front of your vehicle.

When there is strong reflected radiation of the radar signal, for example, in multilevel parking structures.

When vehicles are crossing in front of your vehicle.

When there is oncoming traffic.

When the system cannot detect the traffic situation clearly.

When a stationary obstacle, such as a broken-down vehicle, is in front of your vehicle.

When loads or attachment parts on other vehicles in front of your vehicle protrude to the side, rear, or above the normal vehicle dimensions.

When the vehicle is traveling faster than about 95 mph (150 km/h).

When the original Volkswagen emblem is not installed.

DANGER!

Following other vehicles too closely increases the risk of collisions and serious personal injury or even death.

Always obey applicable traffic laws when setting the distance to the vehicles ahead in traffic.

Setting short distances to the traffic ahead reduces the time and distance available to bring your vehicle to a safe stop and makes it even more necessary

to pay close attention or traffic.

Always use good judgment and select a safe following distance for the traffic, road and weather conditions.

Never use Adaptive Cruise Control on narrow or winding roads or under poor road conditions (snow, ice, streets covered with standing water or gravel, for

example) or when visibility is poor, especially when it is foggy.

Always select a greater following distance to the vehicle ahead on wet roads than on dry roads.

WARNING

183

Improper use of the Adaptive Cruise Control can cause collisions, other accidents and serious personal injury.

Always remember that the Adaptive Cruise Control has limits – it will not slow the vehicle down or maintain the set distance when you drive towards an

obstacle or something on or near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle.

Always remember that the Adaptive Cruise Control cannot detect a vehicle that is driving towards you in your traffic lane and that it cannot detect narrow

vehicles such as motorcycles and bicycles.

Never drive at speeds that are too fast for traffic, road and weather conditions.

Never follow a vehicle so closely that you cannot stop your vehicle safely. The Adaptive Cruise Control cannot slow or brake the vehicle safely when you

follow another vehicle too closely. Always remember that the Adaptive Cruise Control has a braking power that is only about 30% of the vehicle's maximum

braking ability, and the automatic braking function cannot bring the vehicle to a stop.

Never use Adaptive Cruise Control when you cannot drive safely at a steady speed, including on city streets, on winding roads or when road conditions are

poor (for example, on ice, gravel, in fog, heavy rain or on wet roads that increase the risk of hydroplaning).

The radar sensor's vision can be reduced by rain, snow and heavy road spray. These and similar conditions can prevent vehicles up ahead from being

accurately detected and in some cases they may not be detected at all. Do not use ACC when the radar sensors cannot accurately detect vehicles moving

ahead of you in traffic.

Always turn off Adaptive Cruise Control when entering turn lanes, exit lanes and construction zones or in similar situations because the vehicle will

automatically accelerate to the stored speed when the road ahead is clear.

Never rest your foot on the accelerator pedal, especially when the Adaptive Cruise Control is being used because doing so will override the braking

function.

Always pay attention to traffic, especially when Adaptive Cruise Control is switched on.

Always maintain a safe speed and distance between your vehicle and other vehicles while considering the traffic situation. This is the duty of the driver.

Adaptive Cruise Control is merely an aid to the driver.

To prevent unintended operation, always switch ACC off when it is not being used.

It is dangerous to use the Resume feature when the previously set speed is too high for existing road, traffic or weather conditions.

Always select a speed and distance to traffic ahead that is safe and appropriate under the prevailing traffic, road, weather and lighting conditions.

Never allow the closing speed between you and other vehicles to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If

closing speed is too high, you must apply the brakes yourself to reduce the risk of a rear-end crash.

The stored speed is canceled when the ignition or the ACC is switched off.

ACC is automatically deactivated when ASR is switched off.

When to temporarily switch off ACC

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Please deactivate ACC under following conditions due to system limitations ⇒ ꢀ:

When driving around curves, turn lanes, highway ramps, or construction sites; to prevent unwanted acceleration of the vehicle.

When driving through tunnels.

On roads with more than one lane, if other vehicles are driving more slowly in the fast lane. Vehicles in other lanes will normally not be detected and will, in

this case, be passed from the slow lane.

Under bad weather conditions or bad visibility, for example, in heavy rain, snowfall, or fog.

WARNING

Not deactivating Adaptive Cruise Control (ACC) in the situations mentioned above can cause collisions, other accidents, and serious personal injury.

Special driving situations

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Adaptive Cruise Control has physical and system-related limits. The driver may therefore feel that, in certain circumstances, some Adaptive Cruise Control

reactions are unwanted or occur with a delay. You should therefore always be prepared to take full control of the vehicle whenever necessary.

Deceleration to standstill and resuming ACC (Golf and Golf GTI models with automatic transmission only)

If a vehicle traveling ahead brakes to a standstill, the ACC will also brake your vehicle to a standstill. The vehicle is then held stationary by the brakes for no more

than a few seconds. You must press the brake pedal or the vehicle will start moving forward again!

To drive off after a stationary phase, press the

ACC stop-and-go (Golf R models with DSG automated transmission only)

ACC will brake your vehicle to a standstill if the vehicle ahead brakes to a standstill. The vehicle is then held stationary by the brakes. ACC stays active and will

resume speed regulation as soon as you press the accelerator pedal and accelerate.

ACC will not automatically resume in the following situations:

The safety belt is unbuckled.

The vehicle standstill lasts longer than about 3 minutes.

The driver door is opened.

The ignition is switched off.

Driving around curves and traﬃc circles

When driving into a curve and driving out of a long curve, the radar sensor may react to a vehicle in the next lane ⇒ Fig. 129ꢀ . In such situations, the vehicle mig

decelerate unnecessarily or not react to the vehicle in front. In this case, you must either override the ACC by depressing the accelerator, interrupt the braking

procedure by depressing the brake pedal, or press the

button on the multi-function steering wheel ⇒ Using ACCꢀ.

Driving through tunnels

The function of the distance radar may be limited when driving in tunnels. Switch off ACC when driving through tunnels.

Narrow vehicles and vehicles offset to one side

Narrow vehicles and vehicles traveling slightly to the left or right of your vehicle can only be detected by the radar sensor when they are within sensor range

⇒ Fig. 129ꢀ . This applies especially to narrow vehicles such as motorcycles. If required, brake the vehicle yourself.

Narrow vehicles, such as motorcycles traveling ahead, are often detected late or not at all under some circumstances.

Vehicles with oversize loads or special equipment

Under certain circumstances, ACC will not correctly recognize vehicles carrying oversize loads or loads that exceed the vehicle dimensions, like ﬂatbed trailer

trucks.

Switch off ACC when driving behind or while passing such vehicles. If required, brake the vehicle yourself.

Other vehicles changing lanes

Vehicles that change into your lane within a short distance can only be detected by the radar sensor once they are within sensor range ⇒ Fig. 130ꢀ . The result is

delayed reaction by the Adaptive Cruise Control. If required, brake the vehicle yourself.

Stationary vehicles

The ACC will not detect stationary obstacles, such as the end of a trafﬁc jam or a broken down vehicle, or a vehicle approaching you in the same lane.

If a vehicle detected by Adaptive Cruise Control turns or changes lanes and there is a stationary vehicle in front of that vehicle, the system will not react to the

stationary vehicle ⇒ Fig. 130ꢀ . If required, brake the vehicle yourself.

Oncoming vehicles

ACC does not detect oncoming vehicles in your lane.

Metal objects on the road

185

Metal objects on the road, such as tracks or metal plates, can lead to unwanted reactions of the system, such as abrupt braking maneuvers.

Possible radar sensor function impairments

If the radar sensor function is impaired by heavy rain, spray, snow or mud, Adaptive Cruise Control switches off temporarily. A driver information message appears

in the instrument cluster display. Clean the radar sensors as required.

The Adaptive Cruise Control will automatically be available again as soon as the radar sensor is working properly. The message in the instrument cluster display

switches off, and the Adaptive Cruise Control can be reactivated.

Strong reﬂected radiation of the radar signal, for example, in multilevel parking structures, can impair the function of the radar sensor.

Overheated brakes

Adaptive Cruise Control may switch off temporarily if the brakes overheat signiﬁcantly, for example from braking maneuvers or driving down steep slopes. A driver

information message appears in the instrument cluster display. Adaptive Cruise Control cannot be activated.

Adaptive Cruise Control can be activated again once the temperature of the brakes decreases sufﬁciently. The message in the instrument cluster display switches

off. If the message does not go out for a long time, there is a fault.

If the message ACC not available does not switch off, there is a malfunction. Contact your authorized Volkswagen dealer or authorized Volkswagen Service

Facility.

Trailer towing

When towing a trailer, ACC and Front Assist may work only with limited functionality.

WARNING

If ACC brings your vehicle to a complete stop before the system prompts you to brake and the stationary vehicle ahead starts moving, your vehicle will also

start moving automatically. In some cases the radar sensor may be unable to detect obstacles in the vehicle's path. This can result in serious injury and

accidents.

Always check the road ahead before the vehicle pulls away. If necessary, cancel the pulling away procedure by depressing the brake pedal.

WARNING

The view of the radar sensor can be impaired by rain, snow or heavy spray. Under certain circumstances, this could result in the vehicle ahead being detected

inadequately or not at all. Take over yourself if necessary!

Switch Adaptive Cruise Control off when driving through tunnels because the function of the system could be impaired.

Forward Collision Warning (Front Assist)

Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Driver warnings and Autonomous Emergency Braking ꢀ

⇒ Radar sensorꢀ

⇒ Using Front Assistꢀ

⇒ When to temporarily deactivate Front Assist ꢀ

⇒ Pedestrian Monitoringꢀ

⇒ System limitsꢀ

Depending on vehicle equipment, the vehicle may be equipped with Forward Collision Warning (Front Assist), which includes Autonomous Emergency Braking and

Pedestrian Monitoring.

The Forward Collision Warning system, when switched on, uses a radar sensor to help prevent rear-end collisions by providing a warning of a possible collision with

a vehicle on the road ahead within physical and technical limits of the system.

When Front Assist is switched on, the Autonomous Emergency Braking system can automatically apply the brakes within the Front Assist speed range to help

minimize the effects of a collision.

The Front Assist system is not a substitute for the driver's full concentration.

186

WARNING

The Front Assist system technology cannot overcome the laws of physics and system-related limits. Do not allow the increased convenience Front Assist can

provide tempt you into taking extra risks. The driver is always responsible for braking in time. If the Front Assist system issues a warning, immediately apply

the brake to slow the vehicle down or avoid the obstacle, depending on the traffic situation.

Always adjust your speed and driving style to road, traffic, weather, and visibility conditions.

The Front Assist system cannot prevent accidents and serious injuries on its own.

The Front Assist system can issue unnecessary warnings in certain complex driving situations, for example, when driving in tight curves.

The Front Assist system can issue unnecessary warnings when its function is impaired, for example, if the radar sensor is dirty or if the position of the radar

sensor has been changed.

The Front Assist system does not react to animals or vehicles crossing or approaching in the same lane.

If you are unsure if your vehicle has Pedestrian Monitoring, please contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility

before you start driving.

Always be prepared to take full control of the vehicle at all times.

WARNING

Failure to heed warning lights and instrument cluster text messages can result in a collision and serious personal injury.

Never ignore warning lights or text WARNINGS.

NOTE

If you notice that Front Assist doesn't work properly or the sensor is damaged, switch off Front Assist immediately.

See an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance and have the Front Assist system checked.

If Front Assist initiates a braking maneuver, the braking system is under pressure. In this case the brake pedal will feel harder.

Automatic braking maneuvers can be interrupted by depressing the gas pedal, or by moving the steering wheel.

Deactivate the Front Assist system if it does not work as described in this chapter, for example, if multiple unwanted warnings or braking maneuvers occur.

Have the system checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

When the Front Assist system is switched on, the instrument cluster display can be overwritten by displays related to other functions, for example, an incoming

telephone call.

The Autonomous Emergency Braking system can slow your vehicle down to a standstill, but not hold your vehicle permanently. If necessary, apply the vehicle

brakes!

Front Assist is automatically deactivated when ASR is switched off.

Certain settings can be saved in the personalized user profiles ⇒ Personalized user profilesꢀ.

Driver warnings and Autonomous Emergency Braking

Fig. 131 In the instrument cluster display: Advance warning (symbol displayed in color on an instrument cluster with color display).

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Distance warning

187

If the vehicle is traveling within a speed range of about 40–155 mph (65–250 km/h), the system warns the driver with the

symbol in the instrument cluster

display if it detects that the vehicle is driving too close to the vehicle ahead ⇒ ꢀ. No acoustic warning will sound.

The warning period varies according to the trafﬁc situation and your driving style.

Increase the distance between your vehicle and the vehicle ahead.

Advance warning

If the vehicle is traveling within a speed range of about 18–155 mph (30–250 km/h), the system warns the driver with a warning chime and a message in the

instrument cluster display (⇒ Fig. 131ꢀ) if it detects a possible collision with a vehicle or a crossing pedestrian ahead

The warning period varies according to the trafﬁc situation and your driving style.

Brake or take action to avoid the vehicle ahead!

⇒

ꢀ.

However, do not rely solely on Front Assist. Under certain conditions, the reactions of Front Assist may be unexpected or delayed from the driver's viewpoint. Alway

pay attention and take over if necessary ⇒ ꢀ.

Immediate warning

If you fail to react accordingly to the advance warning within a speed range of about 18–155 mph (30–250 km/h), Front Assist may initiate a short active braking

maneuver. In this case you will notice brief, jerky braking of the vehicle to warn you of an impending collision.

The moment of this alert can vary, depending on the trafﬁc situation and the driving behavior.

Autonomous Emergency Braking

If you should also fail to react to the immediate warning, within a speed range of about 3–155 mph (5–250 km/h), Front Assist can initiate an automatic braking

maneuver that will abruptly decelerate the vehicle with elevated braking force. The emergency braking maneuver occurs shortly before a potential collision to

reduce vehicle speed and help to minimize the effects of a collision.

Autonomous Emergency Braking below 18 mph (30 km/h)

In case of an impending collision, within a speed range of about 3–18 mph (5–30 km/h), Front Assist can initiate an automatic braking maneuver without the

advance or immediate warnings to reduce vehicle speed and help to minimize the effects of a collision ⇒ ꢀ.

The automatic braking maneuver occurs simultaneously with a warning in the instrument cluster display ⇒ Fig. 131ꢀ.

Braking support

Front Assist can help to minimize the effects of a collision by providing additional braking force in case of an emergency braking situation within a speed range of

about 3–155 mph (5–250 km/h), should the system detect that the force applied to the brake pedal by the driver is not sufﬁcient to avoid a collision. In order for

Front Assist to provide this additional braking assistance, it must have detected an impending collision with another vehicle ahead of yours and the brake pedal has

to be hit hard and suddenly. However, this support only works as long as the brake pedal is depressed.

Front Assist considers the driver's response time to give warnings in time. This response time decreases automatically when the system, for example, detects

movement of the accelerator or steering wheel. The system thus prevents unnecessary brake interventions, for example, when the driver passes another vehicle.

Front Assist cannot react when approaching standing objects ahead of you, for example, when driving up to a line of stopped vehicles in heavy trafﬁc.

System deactivated

If the system is switched off, a text message and the

symbol appear in the instrument cluster display. The yellow central caution light

may also light up.

Radar sensor

Fig. 132 Behind the Volkswagen emblem: Radar sensor Ⓐ and area around the radar sensor to be kept clean and free of obstructions Ⓑ.

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

A radar sensor behind the Volkswagen emblem monitors trafﬁc ⇒ Fig. 132Ⓐꢀ and can detect vehicles traveling ahead.

The radar sensor function can be impaired by things such as mud, slush, or snow, or by conditions such as heavy rain or spray. In cases like these, Front Assist wil

not work. The driver message Front Assist: no sensor view! appears in the instrument cluster display. Clean the radar sensor as required ꢀ.

⇒

188

The Front Assist system will automatically be available again as soon as the radar sensor is no longer impaired. The message in the instrument cluster display

turns off.

The function of the Front Assist system can also be impaired when the radar signal radiation is reﬂected, for example, in multilevel parking structures, or by nearby

metallic objects such as rails or metal plates in the road.

The area in front of and around the radar sensor ⇒ Fig. 132Ⓑꢀ must not be covered by objects such as stickers, additional headlights, non-standard license plate

brackets, or other things, as these items can impair the function of the Front Assist system.

Any structural modiﬁcations to the vehicle, for example, lowering the vehicle or alterations to the front end trim, can impair the function of the Front Assist system.

Structural modiﬁcations should only be carried out by a qualiﬁed workshop ⇒ Parts, accessories, repairs, and modiﬁcationsꢀ. Contact an authorized Volkswagen

dealer or an authorized Volkswagen Service Facility for assistance.

The Volkswagen emblem affects the function of the radar sensor. Use the original Volkswagen emblem only.

Incorrectly performed repairs to the front end of the vehicle can change the position of the radar sensor and therefore impair the function of the Front Assist system.

Repair work should only be carried out by a qualiﬁed workshop. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for

assistance.

NOTE

Switch off the Front Assist system if you suspect that the radar sensor has been damaged or if its position has been changed. This can help prevent further

damage. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to have the radar sensor realigned.

The radar sensor can become misaligned if it is hit, for example, when parking the vehicle. Readjusting the sensor could impair the performance of the

system or cause it to switch off.

Repairs to the radar sensor require special knowledge and tools. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility

for assistance.

Failure to switch off Front Assist in the situations mentioned can cause accidents and serious personal injury.

Pedestrian Monitoring

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Your vehicle may be equipped with a Pedestrian Monitoring feature that can help prevent accidents with pedestrians crossing the street or help minimize the

outcome of an accident.

The system alerts you of an impending collision, prepares the vehicle for emergency braking, provides support when braking, or performs an automatic braking

maneuver.

If the system gives the driver an advanced warning, a message appears in the instrument cluster to warn the driver of an impending collision ⇒ Driver warnings a

Autonomous Emergency Brakingꢀ.

If the Front Assist system is switched on ⇒ Using Front Assistꢀ, then Pedestrian Monitoring is also active within a speed range of about 3–40 mph (5–65 km/h).

WARNING

The Pedestrian Monitoring technology cannot overcome the laws of physics and system-related limits. Never let the increased convenience provided by the

Pedestrian Monitoring system tempt you into taking extra risks. The driver is always responsible for braking in time. If the Pedestrian Monitoring system issues

a warning, immediately apply the brake to slow the vehicle down or avoid the pedestrian, depending on the traffic situation.

Always adjust your speed, driving style, and the distance you keep between you and the vehicles ahead of you to the road, traffic, weather, and visibility

conditions.

The Pedestrian Monitoring system cannot prevent accidents and serious injuries on its own.

The Pedestrian Monitoring system can issue unnecessary warnings in certain complex driving situations, for example, when driving in tight curves.

The Pedestrian Monitoring system can issue unnecessary warnings or braking maneuvers when its function is impaired, for example, if the radar sensor is

dirty or if the position of the radar sensor has been changed.

The Pedestrian Monitoring system does not react to animals.

Always be prepared to take full control of the vehicle at all times.

Automatic braking maneuvers can be interrupted by depressing the accelerator pedal or by moving the steering wheel.

Deactivate the Front Assist system if it does not work as described in this chapter, for example, if multiple unwanted warnings or braking maneuvers occur.

Have the system checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

System limits

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Blind Spot Monitor with Rear Traﬃc Alert

193

Introduction to the subject

In this chapter you will find information on the following subjects:

⇒ Indicator lightsꢀ

⇒ How Blind Spot Monitor worksꢀ

⇒ Driving situationsꢀ

⇒ Rear Traffic Alertꢀ

⇒ Using the Blind Spot Monitor with Rear Traffic Alert ꢀ

Depending on vehicle equipment, the vehicle may be equipped with the Blind Spot Monitor system.

The Blind Spot Monitor assists the driver by using radar sensors to monitor the trafﬁc in the blind spot detection area as well as trafﬁc behind the vehicle.

The integrated Rear Trafﬁc Alert system can help the driver when backing out of parking spaces and when maneuvering.

The Blind Spot Monitor is only designed for use on paved roads.

WARNING

The Blind Spot Monitor with Rear Traffic Alert technology cannot overcome the laws of physics and limits of the system. Careless or unintentional use of the

Blind Spot Monitor and Rear Traffic Alert may result in accidents and serious injuries.

The Blind Spot Monitor with Rear Traffic Alert is not a substitute for careful and attentive driving.

Always adjust your driving style to road, traffic, weather, and visibility conditions.

Always keep both hands on the steering wheel so that you are prepared to steer at any time.

Pay attention to and heed the indicator lights in the outside mirrors and in the instrument cluster display.

The Blind Spot Monitor may react to certain equipment installed on the side of the road, such as high or offset guardrails. False warnings may result.

Never use the Blind Spot Monitor with Rear Traffic Alert on unpaved roads. The Blind Spot Monitor with Rear Traffic Alert was designed only for paved

roads.

Always pay attention to the area surrounding your vehicle.

Never use the Blind Spot Monitor with Rear Traffic Alert if the radar sensors are dirty, obstructed, or damaged; the function of the system may be impaired.

Sunlight may reduce the visibility of the indicator light in the outside mirror.

NOTE

The radar sensors in the rear bumper can be damaged or become misaligned in low-speed impacts and parking maneuvers. The system can switch itself

off or may be impaired as a result.

Always keep the rear bumper clean and free of snow and ice so that the radar sensors can function properly. Do not cover the radar sensor area.

The rear bumper may only be painted with vehicle paint that is approved by Volkswagen. Other paints may impair the function of the Blind Spot Monitor or

cause it to malfunction.

If the system does not work as described in this chapter or if your vehicle was involved in a collision, do not use the Blind Spot Monitor with Rear Traffic Alert.

See an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to have the system checked.

Certain settings can be saved in the personalized user profiles ⇒ Personalized user profilesꢀ.

When the ignition is switched on, several warning and indicator lights come on brieﬂy for a function check. They go out after a few seconds.

If the indicator light in the outside mirror does not light up, the Blind Spot Monitor does not currently detect a vehicle in the monitored area around your vehicle

ꢀ.

⇒

The brightness of the indicator lights in the outside mirrors are dimmed when the headlights are switched on (night mode).

WARNING

Failure to heed warning and indicator lights and instrument cluster text messages can result in a collision and serious personal injury.

Never ignore warning and indicator lights or text WARNINGS.

Always heed warning and indicator lights and take action where necessary.

NOTE

Failure to heed warning and indicator lights or text WARNINGS can result in vehicle damage.

How Blind Spot Monitor works

Fig. 135 In the outside mirrors: Indicator lights for the Blind Spot Monitor.

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

The Blind Spot Monitor uses sensors in the rear bumper to monitor the blind spot detection area and the area behind your vehicle and informs you via indicator

lights in the outside mirrors. The system measures the distance to other vehicles and the difference in speed between your vehicle and other vehicles. The Blind

Spot Monitor only works at speeds above about 9 mph (15 km/h).

The Blind Spot Monitor automatically deactivates when driving through tight curves in the road. In this situation, the deactivation occurs without a driver information

message. No warnings appear in the mirror glass or in the instrument cluster display. After driving through the curve, the Blind Spot Monitor automatically

reactivates and the system is available again.

Indicator lights in the outside mirrors

The indicator light ⇒ Fig. 135ꢀ in the glass for the respective outside mirror informs you about trafﬁc to the rear, if the system interprets the situation as critical. The

indicator light in the driver side outside mirror informs you about trafﬁc to the left, and the indicator light in the passenger side outside mirror informs you about trafﬁ

to the right of your vehicle.

Tinting the side windows or aftermarket tinting ﬁlms can interfere with the indicator lights in the outside mirrors or cause false readings.

Keep the glass in the outside mirrors clean and free of snow and ice, and do not cover the mirrors with stickers or other objects.

Lane Keeping System (Lane Assist)

For vehicles with Lane Keeping System (Lane Assist): When Lane Assist ⇒ Lane Keeping system (Lane Assist) ꢀ is active, within system limits, the driver will be

warned of a critical situation during a lane change with a steering correction. This happens even if the turn signal is switched on. If the driver ignores the steering

correction, the steering wheel will vibrate as an additional warning.

Radar sensors

The radar sensors are behind the rear bumper on the left and right. They are not visible from outside the vehicle. They monitor an area about 21 yards (20 meters)

behind the vehicle as well as the blind spots on the left and right sides of the vehicle. The monitored area next to the vehicle is about one lane wide.

The width of the lane is not detected individually on each road, but is preprogrammed into the system. Because of this, the indicators may be incorrect when driving

195

on narrow roads or driving in the center of two lanes. Vehicles that are two lanes away from you or stationary objects such as guard rails may also be detected and

cause a false warning.

Driving situations

Fig. 136 Driving situation when passing with traffic behind your vehicle. Arrow: Blind Spot Monitor indicator light in the driver side mirror.

Fig. 137 Driving situation when passing and merging into the lane. Arrow: Blind Spot Monitor indicator light in the passenger side mirror.

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

The following situations result in a signal in the outside mirror ⇒ Fig. 136ꢀ (arrow) or ⇒ Fig. 137ꢀ (arrow):

If your vehicle is being passed by another vehicle ⇒ Fig. 136ꢀ.

When passing another vehicle ⇒ Fig. 137ꢀ, and the difference in speed between the two vehicles is no more than about 6 mph (10 km/h). There is no signal if

the passing speed is clearly faster.

The faster another vehicle approaches, the earlier the signal in the outside mirror appears, because the Blind Spot Monitor reacts to the difference in speed betwee

your vehicle and other vehicles. Therefore, the signals may trigger for different vehicles at different times, even when the distance to those vehicles is the same.

The Blind Spot Monitor only works at speeds above about 9 mph (15 km/h). The system switches off automatically when the vehicle speed drops below about

6 mph (10 km/h).

Physical and system limitations

In certain situations, the Blind Spot Monitor may not interpret the trafﬁc situation correctly. These situations may include:

When driving in tight curves.

When the width of the lanes differs.

When there is a rise in the road surface.

When there are poor weather conditions.

When certain types of equipment are on the side of the road, such as high or offset guard rails.

Rear Traﬃc Alert

Fig. 139 Rear Traffic Alert display (may vary depending on vehicle equipment).

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ

Key to ⇒ Fig. 139ꢀ:

The red area indicates that the system has detected traffic behind the vehicle.

The yellow area indicates that the system has possibly detected traffic behind the vehicle.

There is a system malfunction in the scanned area (not pictured).

The Rear Trafﬁc Alert system uses the radar sensors in the rear bumper to monitor the trafﬁc crossing behind your vehicle when you are backing out of a parking

space or maneuvering, for example, in trafﬁc situations with poor visibility.

A warning sounds if the system detects approaching trafﬁc behind your vehicle when backing up ⇒ Fig. 138ꢀ (red area).

Vehicles without Park Distance Control (PDC): There is a warning tone and a text message in the instrument cluster display.

Vehicles with Park Distance Control (PDC): There is a continuous warning tone from the PDC. If PDC is deactivated, a warning for the driver may not be

possible, and therefore the Rear Traffic Alert is also deactivated.

Automatic braking

If Rear Trafﬁc Alert detects an approaching vehicle and the driver does not press the brake pedal, the system can intervene with automatic braking.

Rear Trafﬁc Alert assists the driver with harsh automatic braking that could help prevent or reduce damage that can result from a collision. Automatic braking occurs

while backing up at speeds between 1–7 mph (1–12 km/h). Once the system detects that your vehicle is not moving, it keeps the vehicle from moving for up to

2 seconds.

After automatic braking, about 10 seconds must pass before the system can brake automatically again.

The driver can interrupt the automatic braking and take control of the vehicle by pressing ﬁrmly on the accelerator or brake pedal.

WARNING

The Blind Spot Monitor with Rear Traffic Alert technology cannot overcome the laws of physics and limits of the system. Careless or unintentional use of the

Blind Spot Monitor and Rear Traffic Alert may result in accidents and serious injuries.

The Rear Traffic Alert is not a substitute for careful and attentive driving.

Never use the system when visibility is limited or in confusing traffic situations, for example, on heavily traveled roads or when there are multiple lanes.

Always watch for people, especially small children, bicycles, animals, and objects, because the Rear Traffic Alert may not always be able to detect them.

Rear Traffic Alert cannot detect people, animals, and things that are moving slowly or not at all.

The Rear Traffic Alert does not always brake the vehicle to a complete stop.

The harsh automatic braking will be uncomfortable for many people, and if you or your passengers have special conditions or sensitivities, particularly in

the neck, you may want to switch off Rear Traffic Alert.
