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 179) 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 195).
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

recommended towing methods can be
employed.
! Before towing the vehicle observe the
following instructions:
R Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the towing eye. Never attach
a tow cable, tow rope or tow rod to the
vehicle chassis, frame or suspension
parts.
! 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.GWarning!
If circumstances require towing the vehicle
with all wheels on the ground, always tow with
a tow bar if:
R the engine will not run
R there is a malfunction in the brake system
R there is a malfunction in the power supply
or in the vehicle’s electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position 2.
If the SmartKey is left in the starter switch
position 0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.GWarning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R the automatic transmission will remain in
park position P
