156 Starting and driving
When the sensors detect an object within
the monitored area, pulses of sound (- - - - -
) will be heard. The frequency of these
pulses increases as the car comes closer to
the object.
If you stop reversing, the sound pulse will
stop after 2 seconds. The sound pulses will
return if you continue to reverse. If the car
moves forward while reverse is engaged,
the system is silenced.
When the distance to the object is less
than 30 cm, a continuous tone will be
heard.
When an object is approximately 90 cm
from the car, the sound pulses change char-
acter markedly (frequency increases).
A distance of about 90 cm is suitable if
you wish to load or unload the luggage
compartment.
NOTICE
The sensors must be kept clean to func-
tion well. Ice, snow and dirt can affect
their sensitivity.
Large quantities of snow or dirt covering
the sensors can prevent the parking aid
system from detecting any objects.
Do not spray the sensors with a pressure
washer, as this can damage them.
Reversing alongside a wall
If the distance between an object and a
corner sensor does not change
for 2 seconds, for example if you are
reversing alongside a wall, the system will
switch to monitoring straight back. The
system indicates if the distance to the wall
decreases again.
Cars with towbar
If the car has a towbar and its wiring is cor-
rectly connected to the car's electrics, the
parking aid system automatically compen-
sates for the protrusion of the towbar.
If a caravan or trailer is hitched up and the
towbar wiring is correctly connected to the
car's electrics, the system is automatically
deactivated.
You can temporarily deactivate the parking
aid system as follows:
• Press the CLR button on the steering
wheel once reverse gear has been
engaged.
The system will be reactivated the next time
you engage reverse.
Error messages
If the system malfunctions, the following
message will appear on the DIC:
Parking assistance
malfunction. Service.
If the system is disrupted by outside interfer-
ence, the following message will be shown
on the DIC:
Parking assistance
sensor interference.
If this message appears, clean the sensors.
The sensors are located in the black trim on
the rear bumper.
