• If the engine stalls, depress the brake pedal or use the hand brake
immediately.
• When following a line of traffic uphill, if you want to prevent the vehicle
from rolling back accidentally when starting off, hold the brake pedal down
for a few seconds before starting off.
Note
The Official Service or a specialist workshop can tell you if your vehicle is
equipped with this system.
Parking aid acoustic system*
Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.
Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors located
on the rear bumper. The measuring range of the sensors starts at approxi-
mately and depending on the nature of the obstacle at a distance of:
• side of the rear bumper: 0.8 m
• middle of the rear bumper: 1.5 m
Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal confirms the activation and correct function of the system.
Reverse gear
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase
rapidly as the vehicle approaches the obstacle.
Within a short distance of about 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further.
Trailer towing
For factory-fitted vehicles with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer, as
the trailer's electric connecter will be plugged into the vehicle.
Possible faults
If a continuous bleep sounds for some seconds when the reverse gear is
engaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the acoustic signal
warning of the fault will not be emitted every time the system is reactivated
(by engaging the reverse gear). Thus, the system ready indication will not
sound either. Have the fault repaired by an Authorised Service Centre as soon
as possible.
If there is no ready signal or no acoustic warning signal, then the parking aid
loudspeaker is faulty and may not warn of obstacles.
To ensure that the system works properly, the sensors must be kept clean and
free of ice and snow.
WARNING
• The sensors have blind spots in which obstacles may not be detected.
• Always look out for small children and animals because the system will
not always detect them. Always pay attention when reversing to avoid acci-
dents.
