172 Controls in detailDriving systemsRear 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.
1SensorsWarning!
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 247).
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.
Center
approx. 59.1 in (150 cm)
Corners
approx. 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.

317 Practical hints
Towing the vehicle
Transporting the vehicle
When transporting the vehicle, you can use
the towing eyes for pulling the vehicle onto
a trailer or transporter. 
Move the gear selector lever to posi-
tion N.

Shift the transfer case to neutral posi-
tion N.

To avoid damaging the vehicle, it
should only be tied down on the
wheels / wheel rims, not on chassis
components such as the transverse
link or trailing arm.Towing the vehicle - various problem
scenarios
Comply with all towing information
(page 315).
In case of engine damage, transmission
damage or malfunctions in electrical
equipment

Move the gear selector lever to posi-
tion N.

Shift the transfer case to neutral posi-
tion N.In case of transfer case damage or for
towing vehicle distances exceeding
30 miles (50 km)
The propeller shafts to the drive axles must
be removed.
In case of front axle damage
Raise the front axle when towing. The pro-
peller shaft between the rear axle and the
transfer case must be removed.
In case of rear axle damage
When the rear axle is raised, the vehicle
can only be towed with a wheel lift or a dol-
ly placed under its front wheels.!When removing drive shaft, place M10
nuts on bolts as distance sleeves and
tighten using M8 nuts.
Always install new self-locking nuts
when reinstalling the drive shaft.

318 Practical hintsTowing the vehicleFront towing eye
In the front, the towing eye is located on
the driver’s side under the bumper.
1Towing eye
Rear towing eye
In the rear, the towing eye is located on the
driver’s side under the bumper.

Freeing a stranded vehicle
Freeing a stranded vehicle, on which the
wheels are dug into sand or mud, should
be done with the greatest of care, especial-
ly if the vehicle is heavily loaded.
Avoid pulling the vehicle jerkily or diago-
nally, since it could result in damage to the
chassis alignment.
Never try to free a vehicle that is still cou-
pled to a trailer.
If possible, a vehicle equipped with trailer
hitch receiver should be pulled backward
in its own previously made tracks.
