Rear Parking Assist*
The Rear Parking Assist system is an elec-
tronic aid designed to assist the driver dur-
ing parking maneuvers. It visually and
audibly indicates the relative distance be-
tween the rear of the vehicle and an obsta-
cle.
The Rear Parking Assist system is auto-
matically activated when you switch on the
ignition and shift the gear selector lever to
positionR.The Rear Parking Assist system monitors
the rear area of your vehicle by means of
four sensors in the rear bumper.

Warning!G
Rear Parking Assist (rear Parktronic) is a
supplemental system. It is not intended to,
nor does it replace, the need for extreme
care. The responsibility during parking and
other critical maneuvers always rests with
the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or
street curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
The operational function of the Rear Parking
Assist can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Rear Parking Assist sensors”
(
page 286).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

Range of the sensors
To function properly, the sensors must be
free of dirt, ice, snow, and slush. Clean the
sensors regularly, being careful not to
scratch or damage them.Minimum distance
The minimum distance between the sen-
sors and an obstacle is approximately
20 in (50 cm). If you encounter an obstacle
in this range, all the warning lamps come
on and you hear a warning signal. If the ob-
stacle is closer than the minimum dis-
tance, the actual distance may no longer
be indicated by the system. Centerapprox. 59.1 in (150 cm)
Cornersapprox. 40 in (100 cm)
!
During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Rear
Parking Assist system will not detect
such objects at close range and dam-
age to your vehicle or the object may
result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Rear Parking Assist system.
