Tires and wheels
Contact an authorized Mercedes-Benz
Center for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase.Important guidelines
Only use sets of tires and rims of the
same type and make.
Tires must be of the correct size for the
rim.
Break in new tires for approximately
60 miles (100 km) at moderate
speeds.
Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss and
damage to the tire beads.
If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.
Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths of less than
1/8in (3 mm).
When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. Contact an authorized
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:
The wheel brakes or suspension
components can be damaged.
The operating clearance of the wheels
and the tires may no longer be correct.
Warning!G
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on re-
treads. The operating safety of the vehicle
cannot be assured when such tires are used.

453 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC) only so far as neces-
sary to have the vehicle moved to a safe
location where the recommended towing
methods can be employed.
When towing the vehicle with all wheels on
the ground or the front axle raised (not per-
missible for vehicles with 4MATIC), the ve-
hicle may be towed only for distances up to
30 miles (50 km) and at a speed not to ex-
ceed 30 mph (50 km/h).
!Vehicles with automatic transmission*
and/or 4MATIC:
Do not tow-start the vehicle.
!Use flatbed or wheel lift/dolly equipment
with SmartKey or SmartKey with KEYLESS-GO*
(Canada only) in starter switch turned to
position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Switch off the ESP
® (page 63) and the auto-
matic central locking (
page 173).
!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing so could
damage the transfer case, which is not covered
by the Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground. Observe
instructions for towing the vehicle with all
wheels on the ground.
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
the engine will not run
there is a malfunction in the brake
system
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 or
SmartKey with KEYLESS-GO* (Canada only)
is in starter switch position2.

454 Practical hints
Towing the vehicle
Warning!G
Without the engine running, there is no pow-
er assistance for the brake and steering sys-
tems. 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.
iWhen towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey or SmartKey with KEYLESS-GO*
(Canada only) in starter switch position 2, the ve-
hicle doors lock if the left front wheel as well as
the right rear wheel are turning at vehicle speeds
of approximately 9 mph (15 km/h) or more.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 173).
!If the vehicle is towed with the front axle
raised (not permissible for vehicles with
4MATIC), the gear selector lever must be in
positionN (manual transmission: gear shift lever
in neutral position) and the engine must be shut
off (SmartKey or SmartKey with KEYLESS-GO*
(Canada only) in starter switch position0 or1).
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
While towing, the battery must be connected and
charged. Otherwise:
you will not be able to switch on the ignition
you will not be able to engage the automatic
transmission* in positionN (
page 127)
When towing the vehicle with all wheels on the
ground, the gear selector lever must be in
positionN (manual transmission: gear shift lever
in neutral position) and the SmartKey or
SmartKey with KEYLESS-GO* (Canada only)
must be in starter switch position2.
!Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach tow cable, tow rope or tow rod to
vehicle chassis, frame or suspension parts.
iTo signal turns while being towed with the
hazard warning flasher in use, turn SmartKey or
SmartKey with KEYLESS-GO* (Canada only) in
starter switch to position2 and activate the
combination switch for the left or right turn sig-
nal in the usual manner – only the selected turn
signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.
!Make sure the parking brake is released.
iIf the battery is disconnected or discharged
the SmartKey or SmartKey with KEY-
LESS-GO* (Canada only) will not turn in the
starter switch
Vehicles with automatic transmission*: the
gear selector lever will remain locked in
positionP (
page 127).
