Windscreen
Heat-reflecting windscreen The heat-reflecting windscreen has a
coating which reflects solar radiation.
Also data signals, e.g. from toll
stations, might be reflected.
The marked areas on the windscreen are not covered with the coating.
Devices for electronic data recording
and fee payment must be attached in
these areas. Otherwise data
recording malfunctions may occur.
Windscreen stickers
Do not attach stickers such as toll
road stickers or similar on the
windscreen in the area of the interior
mirror. Otherwise the detection zone
of the sensor and the view area of the camera in the mirror housing could be restricted.
Manual windows The door windows can be opened or
closed with the window winders.
Power windows9 Warning

power windows. Risk of injury,
particularly to children.
If there are children on the rear seats, switch on the child safety
system for the power windows.
Keep a close watch on the
windows when closing them.
Ensure that nothing becomes
trapped in them as they move.
Power windows can be operated
■ with ignition on,
■ within 5 minutes of switching ignition off,

144Driving and operating
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles. It
is the driver, however, who bears full
responsibility for parking.
The system consists of four ultrasonic parking sensors in each of the front
and rear bumpers.
Control indicator r 3 90.
Notice
Attached parts in the detection area
cause system malfunction.
ActivationWhen reverse gear is engaged, the
system switches itself on
automatically.
The system can also be activated at
low speed by pressing the r button.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets closer to the obstacle. When the
distance is less than 30 cm, the buzzer is continuous.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Deactivation
Deactivate the system by pressing
the r button.
The system automatically switches itself off when the vehicle is driven above a certain speed.
Towing equipment
The system automatically detects
factory-fitted towing equipment.
The rear parking sensors are
deactivated when towing.
