Area monitoring system (Front Assist)

Introduction to the topic

The area monitoring system (Front Assist) with City Emergency Braking System and Pedestrian

Monitoring can help to avoid accidents.

Within the limits of the system, Front Assist can warn the driver about imminent collisions,

prepare the vehicle for emergency braking, assist with braking, and initiate automatic braking.

The warning time varies depending on the traffic situation and driver behaviour.

Front Assist is not a substitute for the full concentration of the driver.

Driving with Front Assist

You can cancel the automatic braking interventions of Front Assist by steering or pressing the

accelerator.

Automatic braking

Front Assist can decelerate the vehicle to a standstill. The vehicle will then not be held

permanently. Depress the brake pedal.

The brake pedal will feel harder during an automatic braking operation.

Radar sensor

Front Assist detects driving situations by means of the radar sensor at the front of the vehicle.

The range of the radar sensor is up to approximately 120 m.

Functions included in the system

The City Emergency Braking System and Pedestrian Monitoring (depending on vehicle

equipment) are part of Front Assist and are automatically active when Front Assist is switched

on.

WARNING

The intelligent technology used in Front Assist cannot overcome the physical limits specified,

and functions only within the limits of the system. Never let the extra convenience afforded by

Front Assist tempt you into taking risks when driving. The driver is always responsible for

braking in time.

●

If Front Assist issues a warning, brake your vehicle immediately depending on the traffic

situation or avoid the obstacle.

●

Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and

traffic conditions.

●

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

Front Assist can issue unnecessary warnings and carry out unwanted braking interventions

in certain complex driving situations, e.g. at traffic islands.

●

Front Assist can issue unnecessary warnings and carry out unwanted braking interventions

when its function is impaired, e.g. if the radar sensor is dirty or its position has been

changed.

Front Assist without Pedestrian Monitoring does not react to persons. In addition, the

system does not react to animals or to vehicles that are crossing or approaching in the same

lane.

●

If you are unsure whether your vehicle possesses Pedestrian Monitoring, please enquire

about this at a qualified workshop before starting your journey.

Be prepared to take over control of the vehicle yourself at all times.

Warning levels and braking intervention

Front Assist can detect the following objects within the system limits and depending on the

vehicle equipment:

—Pedestrians and vehicles also moving relative to your vehicle.

—Crossing pedestrians.

—Stationary vehicles.

Front Assist can provide assistance and intervene if the vehicle is approaching a detected object

in such a way that a collision with the object will occur if the vehicle speed is maintained and

there is no driver intervention. The system first issues an advance warning, then an urgent

warning, and finally performs automatic braking.

Under ideal conditions, this can prevent a collision or help to reduce the consequences of the

collision.

Front Assist operates in the following speed ranges:

The values apply only under ideal conditions and are approximate values.

Advance warning

The system detects a possible collision with a vehicle ahead and prepares the

vehicle for emergency braking.

An acoustic warning sounds and the red warning lamp lights up. Brake or take avoiding action.

Urgent warning

If the driver does not react to the advance warning, the system may initiate a short braking jolt in

order to draw attention to the increasing collision risk. Brake or take avoiding action.

Automatic braking

If the driver also does not react to the urgent warning, the vehicle can be braked automatically

with braking force that increases in several stages. The reduced speed means that it is possible to

minimise the consequences of an accident.

Braking intervention

If the system detects that the driver is braking insufficiently when there is a risk of collision, the

system can increase the braking force and help prevent a collision. The braking intervention takes

place only for as long as the brake pedal is pressed hard.

City Emergency Braking System

The City Emergency Braking System is part of Front Assist. If the driver does not react to a

possible collision, the system can also automatically brake the vehicle with increasing braking

force without any advance warning.

The red warning lamp lights up

Distance warning

The system detects when safety is endangered by driving too close to the vehicle

in front. The indicator lamp lights up. Increase the distance.

Speed range: approx. 65 km/h (40 mph) to 250 km/h (155 mph).

Limits of Front Assist

Front Assist has physical and system-related limitations. You should therefore always be

prepared to take full control of the vehicle if necessary.

Delayed response

If the radar sensor is exposed to environmental conditions that impair sensor functioning, the

system may detect this only after a certain delay. For this reason, any restrictions to functions

may be displayed only after a delay at the start of the journey and when driving (→ Autonomous

Emergency Braking (Front Assist), Introduction/General information).

Objects that cannot be detected

Front Assist may not react or may react with a delay or provide with an unwanted response in the

following situations:

—Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g.

vehicles that are driving offset to your vehicle or motorbikes.

—Vehicles that change into your lane directly in front of your vehicle.

—Vehicles with bodies or attachments that project beyond the vehicle.

—Oncoming vehicles or vehicles crossing your path.

—Pedestrians who are standing still or coming towards the vehicle.

Function limitations

Front Assist may not react or may react with a delay or provide with an unwanted response in the

following situations:

—In tight bends.

—Driving in heavy rain, snow or heavy spray.

—Driving in multi-storey car parks.

—Driving on roads with embedded metal objects, e.g. railway tracks.

—Reversing.

—If TCS is switched off manually.

—If ESC is taking corrective action.

—If the radar sensor is dirty or covered.

—If several brake lights on the vehicle are faulty.

—If the vehicle accelerates hard or the accelerator is fully depressed.

—In complex driving situations, e.g. at traffic islands.

—In unclear traffic situations, e.g. vehicles ahead are braking heavily or turning off.

—If there is a fault in Front Assist.

Switching off Front Assist

Front Assist is not suitable for use in the following situations due to the limitations of the system

and must be switched off →

:

—If the vehicle is used in a capacity other than driving in normal traffic, e.g. offroad.

—If the vehicle is being towed or is loaded onto another vehicle.

—If the radar sensor is covered temporarily by add-on parts, e.g. auxiliary headlights.

—If the radar sensor is faulty.

—After external force on the radar sensor, e.g. after a rear-end collision.

—In the event of multiple unwanted interventions.

WARNING

Failure to switch off Front Assist in the situations mentioned can result in accidents and serious

injuries.

Pedestrian Monitoring

Pedestrian Monitoring can help to avoid accidents with pedestrians crossing the vehicle's path

or to mitigate the consequences of an accident.

The system gives a warning when there is a risk of collision, prepares the vehicle for emergency

braking, helps to brake the vehicle or performs an automatic brake intervention. In the event of

an advance warning, the red warning lamp lights up in the instrument cluster display.

When Front Assist is switched on, Pedestrian Monitoring is active as part of Front Assist in a

vehicle speed range from approx. 5 km/h (3 mph) to 65 km/h (40 mph).

Pedestrian Monitoring is not available in all countries, depending on the vehicle equipment level.

WARNING

The intelligent Pedestrian Monitoring technology cannot overcome the physical limits

specified, and functions only within the limits of the system. Never let the extra convenience

afforded by the Pedestrian Monitoring system tempt you into taking any safety risks when

driving. The driver is always responsible for braking in time.

●

If Pedestrian Monitoring issues a warning, brake your vehicle immediately depending on the

traffic situation or avoid the pedestrian.

●

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

Pedestrian Monitoring can issue unnecessary warnings and carry out unwanted braking

interventions in complex driving situations, e.g. on a main road that turns sharply.

●

Pedestrian Monitoring can issue unnecessary warnings and carry out unwanted braking

interventions when its function is impaired, e.g. if the radar sensor is covered or its position

has been changed.

Be prepared to take over control of the vehicle yourself at all times.

Operating the area monitoring system (Front Assist)

Front Assist and the advance warning (in some countries) are automatically switched on when

you switch on the ignition.

Volkswagen recommends that Front Assist and also the distance and advance warnings are

switched on at all times. Exceptions (→ Autonomous Emergency Braking (Front Assist),

Limits/System limits).

Switching on and off

—Switch Front Assist on and off in the vehicle settings of the Infotainment system (→ Vehicle

settings menu, Operation).

—Or: switch Front Assist on and off in the instrument cluster menus (→ Menus and information

displays, Overview).

If you switch off Front Assist, the advance warning and distance warning will also

be switched off. The yellow indicator lamp lights up in the instrument cluster

display.

Setting the distance and advance warnings

When Front Assist is switched on, you can adjust the distance and advance warnings as follows:

—Switch the desired function on and off in the vehicle settings of the Infotainment system (→

Vehicle settings menu, Operation).

Depending on the vehicle equipment, you can also set the warning time for the advance warning.

Some settings can be stored in the user accounts of the personalisation function and

therefore change automatically when the user account changes (→ Personalisation,

Description).

Troubleshooting

Front Assist is not available, the radar sensor does not have sufficient

visibility.

—The radar sensor is dirty. Clean the radar sensor (→ Vehicle care, Description).

—The view of the radar sensor is impaired due to the weather conditions, e.g. snow, or due to

detergent deposits or coatings. Clean the radar sensor (→ Vehicle care, Description).

—The view of the radar sensor is impaired by add-on parts, the trim frames of number plate

holders or stickers. Keep the area around the radar sensor free.

—The radar sensor has been displaced or damaged, e.g. due to damage to the front of the

vehicle. Check whether damage is visible (→ Repairs and technical modifications,

Standards/Directives).

—Structural modifications have been made to the front of the vehicle.

—If the problem persists, switch off Front Assist and go to a qualified workshop.

Front Assist does not function as expected or is triggered unnecessarily

several times.

—The radar sensor is dirty. Clean the radar sensor (→ Vehicle care, Description).

—The system limits have been exceeded (→ Autonomous Emergency Braking (Front Assist),

Limits/System limits).

—If the problem persists, switch off Front Assist and go to a qualified workshop.
