 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.

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.

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.
The indicator lamp will be lit up if the city emergency brake function is switched off, is working or if
there is a fault in the system.
Lit upPossible cause ⇒Solution
The city emergency brake function
was switched on using the button
⇒ Fig. 109.
The indicator lamp is switched off
automatically after approximately 5
seconds.
FlashesPossible cause ⇒Solution
Quickly: city emergency brake function
is braking automatically or has braked
automatically.
Indicator lamp will go out automatically.
Slowly: city emergency brake function
currently not available.
While the vehicle is stationary, switch off
the engine and re-start it again. If
necessary, inspect the laser sensor (for
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.
WARNING
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.

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.
Failure to observe the warning lamps could lead to your vehicle breaking down in traffic, and
to accidents and serious injuries.
•Never ignore any warning lamps that are lit up.
•Stop the vehicle as soon as possible and when safe to do so.
WARNING
Failure to observe the illuminated indicator lamps could lead to the vehicle being damaged.

Introduction
Switching the city emergency brake function on and off
•Press the ⇒ Fig. 109 button in the centre console.
When the city emergency brake function is switched off, the indicator lamp lights up
when the vehicle is travelling at 5 – 30 km/h (3 – 19 mph).
Switch off the city emergency brake function in the following situations
The city emergency brake function should be switched off in the following situations ⇒:
•If the vehicle is being towed.
•If you are driving the vehicle through an automatic car wash.
•If the vehicle is on a rolling road test bed.
•If the laser sensor is faulty.
•If the laser sensor has been hit or moved with force.
•If the vehicle is being driven off-road (e.g. through low-hanging branches).
•If there are protruding objects in the area above the bonnet, e.g. a load on the roof that sticks
out at the front.
•If the windscreen is damaged in the area around the laser sensor.
•Driving with tailgate open.
•In the event of multiple unwanted interventions.
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!
WARNING
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.

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 will flash in
the instrument cluster display.
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.
Accidents and serious injuries could occur if you do not switch off the city emergency brake
function during any of the situations named above.
•Switch off the city emergency brake function during critical driving situations.
