Auto-dimming rear view mirrors
The exterior rear view mirror on the driver’s
side and the interior rear view mirror will
respond automatically to glare when the
ignition is switched on and incoming light
from headlamps falls on the sensor in the
interior rear view mirror.
The rear view mirrors will not react if the
automatic transmission is set to reverse gear
R or the interior lighting is switched on.
GWarning!
The auto-dimming function does not react if
incoming light is not aimed directly at sensors
in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident.

Failure to observe these guidelines could
cause the vehicle to skid.
The 4MATIC cannot prevent accidents
resulting from excessive speed.
! When towing the vehicle with all wheels
on the ground, the gear selector lever must
be in neutral position N and the SmartKey
must be in starter switch position 2.
When towing the vehicle with all wheels on
the ground, the vehicle may be towed only
for distances up to 30 miles (50 km) and at
a speed not to exceed 30 mph (50 km/h).
If the vehicle is towed with one axle raised
(observe instructions regarding flexible
drive shaft and propeller shafts), the engine
must be shut off and the SmartKey must be
in starter switch position 1. Otherwise, the
4-ETS may become engaged which may
cause loss of towing control.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system and/or the transfer case which is
not covered by the Mercedes-Benz Limited
Warranty.
iIn winter operation, the maximum
effectiveness of the 4MATIC is only
achieved with winter tires (Y page 175) or
snow chains as required.
Rear Parking Assist system
The Rear Parking Assist system is an
electronic parking aid with ultrasonic sensors
designed to assist the driver during parking
maneuvers. It indicates the relative distance
between the rear of the vehicle and an
obstacle visually and audibly.
The Rear Parking Assist system is activated
automatically when you switch on the ignition
and the automatic transmission is in reverse
gear R.
The Rear Parking Assist system monitors the
rear surroundings of your vehicle with four
sensors in the rear bumper.
To function properly, sensors : must be free
of dirt, ice, snow and slush. Clean
sensors : regularly, being careful not to
scratch or damage sensors :, see “Cleaning
the Rear Parking Assist system sensors”
(Y page 190).
GWarning!
The Rear Parking Assist 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 remains with the driver.
GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). The
Rear Parking Assist system will not detect

such objects at close range and damage to
your vehicle or the object may result.
! Ultrasonic signals from outside sources
(e.g. truck air brakes, car wash, or
jackhammers) may impair the operation of
the Rear Parking Assist system.
Range of the sensors
Sensors
Centerapprox. 59 in (150 cm)Cornersapprox. 40 in (100 cm)
Minimum distance
Centerapprox. 8 in (20 cm)Cornersapprox. 8 in (20 cm)
If the Rear Parking Assist system detects an
obstacle in this range, all the distance
warning segments illuminate and you hear a
warning signal. If the obstacle is closer than
the minimum distance, the actual distance
may no longer be indicated by the Rear
Parking Assist system.
Warning indicators
Visual signals indicate to the driver the
relative distance between the sensors and an
obstacle.
The warning indicator is divided into four
yellow and two red distance segments :.
The Rear Parking Assist system is ready to
measure when you hear a signal and
readiness indicator ; is illuminated.
As your vehicle approaches an object, one or
more distance segments : will illuminate,
depending on the distance. When the sixth
distance segment illuminates, you have
reached the minimum distance.
An intermittent acoustic warning will sound
when the fourth yellow distance segment
illuminates. This signal quickens with each
additional distance segment lit. When the
sixth distance segment illuminates, the
acoustic warning becomes a constant signal.
The signal is canceled when the automatic
transmission is shifted into drive position D,
or park position P.
