Acoustic parking
system
Rear acoustic park assist
Applies to vehicles: with 4-channel acoustic park assist
Acoustic park assist gives a warning about
obstacles behind the vehicle.
Description
The rear acoust ic park assist (4-channe l
acoust ic pa rk assist) dete rmines the distance
of the vehicle from an obstacle using ultra-
sonic sensors . The sensors are in the rear
bumper . The volume and the pitch of the
chimes can be adjusted through the menu dis-
play
c::>page 27 .
The range at which the sensors start to meas-
ure is
about:
To the side
Center rear
Activation
2 feet (0.60 m)
S feet (1.60 m)
The parking assist is activated when reverse
gear
is engaged. A brief tone confirms t hat
the system is activated.
Backing up
Distance warning when backing up starts
when an obstacle is detected in the range of
the park assist system. As t he distance de-
creases, t he time interva l between the audib le
tones becomes sho rter.
When the distance is less than 1 foot (0.30
m), the tone becomes cont inuous . At t his
point you should stop backing up.
Please note that low objects already signalled
by a wa rning can disappear from the system 's
detection range and will not continue to be
signa lled.

Potent ial malfunct ions
If a warning buzzer sounds for a few seconds
when the ignition is switched on, there is a
system malfunction with the acoustic park as -
sist. If the ma lfunction persists unti l the igni-
tion is switched off, there will be no aco ustic
warning at the next attempt to act ivate the
system. Have the prob lem corrected.
There is no conf irmation tone when reve rse
gear is engaged if there is a system malfunc-
tion.
For t he parking assist to ope rate, the sensors
must be kept clean and free of ice.
A WARNING
- Sensors have blind spots in wh ich objects
cannot be detected. Pay spec ial attent ion
to small children and animals . They can-
not always be detected by the sensors -
danger of an accident!
- The parking assist cannot replace the
driver's atte ntion. The driver alone is re-
sponsib le for pa rking and simi lar driving
maneuve rs. Always wat ch whe re you are
driving.
(D Note
Low obstacles already signa lled by a warn-
ing can disapp ear from the system's detec-
tion range as they are approached and will
not cont inue to be signalled. Objects such
as barrier chains, trailer draw bars, th in
painted vertica l poles, or fences may not
be detected by the system - risk of dam-
age.
(D Tips
For the parking assist to operate, the sen-
sors must be kept clean and free of snow
and ice.
