ParkPilot

Introduction

This chapter contains information on the followingsubjects:

⇒ Operating ParkPilot

⇒ Acoustic and optical ParkPilot signals at the rear of the vehicle

The ParkPilot assists the driver when manoeuvring and parking.

The ultrasound sensors in the rear bumper transmit and receive ultrasonic waves. The system uses

the time difference between the ultrasonic waves (i.e. between the transmission and reflection from

obstacles and the point of reception) to continuously calculate the distance between the bumper

and the obstacle.

WARNING

The ParkPilot cannot replace the full concentration of the driver.

•

Unintentional vehicle movements can cause serious injury.

Always adapt your speed and driving style to suit visibility, weather, road and traffic

conditions.

•

Ultrasound sensors have blind spots in which obstacles and people cannot be detected.

Always monitor the area around the vehicle as the ultrasound sensors will not always

detect infants, animals and objects.

•

Certain surfaces of objects and clothes cannot reflect the signals from the ultrasound

sensors. The system is unable to detect these objects or people wearing this type of

clothing, or they may be detected incorrectly.

External sources of sound can affect the signals of the ultrasound sensors. In certain

circumstances, the system may not recognise people or objects.

NOTICE

•

The ultrasound sensors may not always be able to detect objects such as trailer drawbars,

thin rails, fences, posts, trees and open or opening tailgates. This can result in damage to

your vehicle.

•

If the ParkPilot has detected an obstacle and issued a warning, the obstacle may move out

of the detection range of the ultrasound sensors as the vehicle approaches it, particularly if

the object is very high or very low. These objects are no longer registered.

•

The vehicle can sustain considerable damage if the warning given by the ParkPilot is

ignored.

The ultrasound sensors in the bumper can be displaced or damaged through impacts, e.g.

when parking.

The ultrasound sensors in the bumper must be kept clean and free of ice and snow, and

must not be covered up by stickers or other objects, as this will prevent the system from

working properly.

•

The ultrasound sensors should only be sprayed briefly when cleaning with pressure hoses

and steam cleaners. A distance of more than 10 cm between the ultrasound sensors and

the steam/hose nozzle must be observed.

•

Sources of noise can lead to errors in the ParkPilot system, e.g. rough asphalt,

cobblestones, induction loops, building equipment, or interference from other vehicles.

Any equipment that has been retrofitted to the vehicle, e.g. bicycle carriers, can prevent

the ParkPilot from functioning properly.

Please contact a qualified workshop if there is a fault in the system. Volkswagen

recommends using a Volkswagen dealership for this purpose.

Volkswagen recommends that drivers practise using the ParkPilot in a traffic-calmed area or

car park to allow them to familiarise themselves with the system and its functions.

Operating ParkPilot

Things to note about ParkPilot

•

In some cases, the ParkPilot registers water and ice on the ultrasound sensors as an obstacle.

•

The acoustic signal will become quieter after a few seconds if the distance remains the same.

The volume will remain constant if the acoustic warning is continuous.

•

As soon as the vehicle moves away from the obstacle again, the intermittent acoustic warning is

switched off automatically. If the vehicle approaches the obstacle again, the acoustic warning is

switched on automatically.

A Volkswagen dealership can adjust the volume of the acoustic signals.

If there is a function fault in the ParkPilot, an acoustic warning is emitted for approximately 3

seconds when switched on for the first time. The ParkPilot should be immediately checked by a

qualified workshop.

Depending on equipment level the areas to the rear of the vehicle that are scanned by the

ultrasound sensors are shown in the display of the portable navigation system (delivered by

Volkswagen). The positions of potential obstacles are displayed relative to the vehicle ⇒

.

Acoustic signals and screen

Acoustic signals are given when the vehicle approaches an obstacle located to the rear. An

intermittent acoustic warning is given if there is sufficient distance between the vehicle and an

obstacle. The shorter the distance, the shorter the intervals. The acoustic warning will sound

continuously if the obstacle is very close.

If you continue to drive the vehicle closer to the obstacle despite the continuous acoustic warning,

the system will no longer be able to measure the distance.

Depending on the vehilcle equipment level, the scanned areas are displayed as several segments

in a display ⇒ Fig. 105. The closer the vehicle drives towards an obstacle, the closer the segment

will move to the vehicle in the display. The collision area has been reached when the penultimate

segment is displayed, if not before. Do not drive on!

Cruise control system (CCS)

Introduction

This chapter contains information on the followingsubjects:

⇒ Indicator lamp

⇒ Using the cruise control system (CCS)

The cruise control system (CCS) helps to maintain a specific preset speed during forward travel at

approx. 20 km/h (15 mph) and higher.

The CCS only slows the vehicle by easing off the accelerator, not by actively braking ⇒

.

Additional information and warnings:

•

Changing gear ⇒ Changing gear

Accessories, modifications, repairs and renewal of parts ⇒ Accessories, modifications, repairs

and renewal of parts

WARNING

The use of the cruise control system can lead to accidents and serious injuries if traffic does

not allow you to drive at a safe distance from the vehicle in front at a constant speed.

•

Never use the CCS in heavy traffic, on steep or winding roads, or on slippery road

surfaces e.g. on snow, ice, wet roads, loose chippings, or on flooded roads.

•

Never use the CCS when driving off-road or on unsurfaced roads.

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

traffic conditions.

•

Always switch cruise control off after use to avoid unintentional operation.

It is dangerous to use a set speed that is too high for the prevailing road, traffic or weather

conditions.

•

The CCS cannot maintain a constant speed when travelling downhill. The vehicle speed

can increase under its own weight. Shift down a gear or brake the vehicle using the foot

brake.

City emergency brake function

Introduction

This chapter contains information on the followingsubjects:

⇒ Warning and indicator lamps

⇒ Laser sensor

⇒ Switching city emergency brake function on and off

⇒ Special driving situations

Within the speed range of approximately 5 – 30 km/h (3 – 19 mph), the city emergency brake

function monitors the traffic situation up to a distance of about 10 m in front of the vehicle.

The system prepares the vehicle for emergency braking if it detects a possible collision with a

vehicle ahead ⇒

.

If the driver does not react to a possible collision, the system can brake the vehicle automatically in

order to reduce the speed ahead of a possible collision.

If, in a potential collision scenario, the city emergency brake function detects that the driver is

applying the brakes with insufficient pressure, the system can increase the brake pressure in order

to reduce speed ahead of the collision. Hence the system can help minimise the consequences of

an accident.

WARNING

The intelligent technology of the city emergency brake function cannot change the laws of

physics or the system-related vehicle limitations. Never let the extra convenience afforded by

the city emergency brake function tempt you into taking any risks when driving. The driver is

always responsible for braking in time.

•

The city emergency brake function cannot prevent accidents and serious injuries by itself.

The city emergency brake function can carry out unwanted brake interventions in certain

complex situations, e.g. if a vehicle cuts very closely in front of you.

WARNING

Incorporating the city emergency brake function into your own driving style can cause

accidents and serious injuries. The system is not a substitute for the full concentration of the

driver.

•

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

traffic conditions.

The city emergency brake function does not react to persons, animals and vehicles

crossing or approaching in the same lane.

Brake the vehicle by depressing the brake if the vehicle rolls forwards once the city

emergency brake function has been applied.

NOTICE

Switch off the city emergency brake function if you suspect that the laser sensor has been

damaged. This can help to prevent further damage.

•

Repairs to the laser sensor require specialist knowledge. Volkswagen recommends using

a Volkswagen dealership for this purpose.

The brake pedal travel decreases when the city emergency brake function is triggered. This

may make the brake pedal feel stiffer.

Automatic brake intervention by the city emergency brake function can be stopped by using

the clutch, the accelerator or steering intervention.

Unusual noises may be heard if the city emergency brake function is applying an automatic

braking procedure. This is normal and the noises are caused by the braking system.

Warning and indicator lamps

First read and observe the introductoryinformation and safety warnings⇒

Introduction

The city emergency brake function is switched on every time the ignition is switched on. No display

will be shown to alert you of this.

Laser sensor

Fig. 107 On the windscreen: laser sensor for the city emergency brake function

Fig. 108 Detection range of the laser sensor

First read and observe the introductoryinformation and safety warnings⇒

Introduction

The system monitors the traffic in front of the vehicle using a laser sensor in the windscreen

⇒ Fig. 107.

Vehicles travelling ahead can thus be recognised up to a distance of approximately 10 m.

WARNING

The beam from the laser sensor could cause severe damage to the eyes.

•

Never use optical devices, such as a rangefinder camera, microscope or magnifying glass,

to look into the laser sensor from a distance of less than 100 mm.

•

Please be aware that the laser beam may still be active even if the city emergency brake

function is switched off or unavailable. The laser beam is not visible to the human eye!

NOTICE

The city emergency brake function may not work if the area on the windscreen around the

laser sensor is iced over, dirty or covered, for example from rain, spray or snow or by roof

loads protruding over the front of the vehicle.

•

Always keep the area around the laser sensor free from dirt and ice and do not cover it.

Remove snow with a brush, and remove ice preferably with a solvent-free de-icer spray.

NOTICE

The city emergency brake function may fail to work if the windscreen is damaged in the area

around the laser sensor.

•

Have the windscreen replaced if it is scratched, cracked or chipped in the area around the

laser sensor. Only use windscreens that have been approved by Volkswagen. Do not

simply have the windscreen repaired (for example, if it has been damaged by stone

chipping).

•

When changing the windscreen wiper blades only use wiper blades that are the same

production quality as the factory-fitted wiper blades.

Do not paint the windscreen in the area around the laser sensor or cover the area with

stickers, deposits or similar.

•

Switch off the city emergency brake function during critical driving situations.

Special driving situations

Fig. 110 A: vehicle in a bend B: motorbike in front is outside the range of the laser sensor

Fig. 111 Vehicles changing lanes

First read and observe the introductoryinformation and safety warnings⇒

Introduction

The city emergency brake function has physical and system-specific limits. In certain situations, the

driver may therefore feel that the city emergency brake function reacts too late or unexpectedly.

You should therefore always be prepared to take full control of the vehicle if necessary.

The following driving situations demand particular vigilance:

When driving through bends

When driving into or out of a long bend, the laser sensor may react to a vehicle in the adjacent lane

⇒ Fig. 110A and thus brake the vehicle. The braking effect can be stopped by pressing the

accelerator or clutch pedal or by steering the vehicle.

Narrow vehicles and a zig-zag traffic situation

Narrow vehicles and vehicles travelling slightly to the left or right of your vehicle will only be

recognised by the laser sensor once they have entered the range of the sensor ⇒ Fig. 110B. This

particularly applies to narrow vehicles such as motorcycles.

When other vehicles change lanes

Vehicles that are very close to you when they move into your lane could cause the city emergency

brake function to be applied unexpectedly ⇒ Fig. 111. The braking effect can be stopped by

pressing the accelerator or clutch pedal or by steering the vehicle.

Possible laser sensor function impairments

The city emergency brake function will switch off temporarily if the function of the laser sensor is

impaired due to heavy rain, spray, snow or mud, for example. The indicator lamp

the instrument cluster display.

will flash in

The city emergency brake function is ready to work again as soon as the laser sensor returns to

normal function. The indicator lamp goes out.

The following conditions could prevent the city emergency brake function

from reacting:

•

If ESC is active.

In tight bends.

If the vehicle is reversing.

When you drive faster than 30 km/h for a few seconds.

If the accelerator is fully depressed.

If the city emergency brake function is switched off or if there is a fault in the system ⇒ Warning

and indicator lamps.

•

If the laser sensor is dirty, covered or overheated ⇒ Laser sensor.

In snow, heavy rain or thick fog.

If vehicles are travelling slightly to the left or right of your vehicle.

If vehicles are crossing in front of your vehicle.

•

If vehicles are travelling towards you in the same lane.

If the surrounding vehicles are very dirty and therefore not very reflective.

If there is a lot of dust.

Introduction

This chapter contains information on the followingsubjects:

⇒ Controls

⇒ General information on the heating and fresh air system

⇒ Information on the air conditioning system

⇒ Vents

⇒ Air recirculation mode

Dust and pollen filter

The dust and pollen filter reduces the level of impurities in the outside air entering the vehicle.

The dust and pollen filter must be changed regularly to avoid impairing the performance of the air

conditioning system.

The dust and pollen filter must be changed more frequently than stated in the service schedule if

the efficiency of the filter declines prematurely due to the vehicle being used in areas with high

levels of air pollution.

WARNING

Poor visibility through all windows increases the risk of collisions and accidents, which can

cause serious injuries.

•

Always ensure that all windows are free of ice, snow and mist to ensure good visibility.

Maximum heat output, which is needed to defrost the windows as quickly as possible, is

only available when the engine has reached its operating temperature. Do not start your

journey until you have good visibility.

•

Always ensure that the heating and fresh air system or the air conditioning system and the

heated rear window are used correctly in order to have good visibility.

Never use the air recirculation mode for an extended period. If the cooling system is

switched off, the windows can mist up very quickly in air recirculation mode and reduce

visibility considerably.

•

Always switch off the air recirculation mode when it is not required.

WARNING

Stale air can quickly cause tiredness and lack of concentration in the driver, which in turn can

cause collisions, accidents and serious injuries.

•

Never switch off the blowers or switch on the air recirculation mode for an extended period

as this prevents fresh air from entering the vehicle interior.

NOTICE

•

Switch off the air conditioning system if you suspect that it has been damaged. This can

help to prevent further damage. The air conditioning system should be checked by a

qualified workshop.

•

Repairs to the air conditioning system require specialist knowledge and special tools.

Volkswagen recommends using a Volkswagen dealership for this purpose.

If the cooling system is switched off, the outside air that is drawn into the vehicle is not

dehumidified. To prevent the windows misting over, Volkswagen recommends that you leave the air
