244 OperationTires and wheels
Tires and wheelsSee your authorized Mercedes-Benz Cen-
ter for information on tested and recom-
mended rims and tires for summer and 
winter operation. They can also offer ad-
vice concerning tire service and purchase
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous 
damage cannot always be recognized on 
retreads. Mercedes-Benz can therefore 
not assure the operating safety of the vehi-
cle when such tires are used.
See your authorized Mercedes-Benz Cen-
ter for information on tested and recom-
mended rims and tires for summer and 
winter operation.
Important guidelines
Use only 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 pressure loss and damage to 
the tire beads
If vehicle is heavily loaded, check tire 
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 under 
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. See your authorized 
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are 
mounted:
The wheel brakes or suspension compo-
nents can be damaged.
The correct operating clearance of the 
wheels and the tires are no longer guar-
anteed.
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, use only genuine 
Mercedes-Benz wheel bolts specified for the 
particular rim type. Failure to do so can re-
sult in the bolts loosening and possibly an 
accident.

313 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the 
ground using flatbed or appropriate wheel 
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the 
recommended towing methods, the vehi-
cle may be towed with all wheels on the 
ground or front wheels raised only so far as 
necessary to have the vehicle moved to a 
safe location where the recommended 
towing methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with SmartKey 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 tow-away alarm 
(page 79) and deactivate the auto-
matic central locking (
page 129).
!Vehicles with automatic transmission:
Do not tow-start the vehicle.
!If the vehicle is towed with the front 
axle raised, the engine must be shut off 
(SmartKey in starter switch position0 
or1). Otherwise, the ESP will immedi-
ately be engaged and will apply the rear 
wheel brakes.
When towing the vehicle with all wheels 
on the ground, the gear selector lever 
must be in positionN (manual trans-
mission: gears disengaged) and the 
SmartKey must be in starter switch 
position2.
When towing the vehicle with all wheels 
on the ground or the front axle raised, 
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a 
speed not to exceed 30 mph 
(50 km/h).

315 Practical hints
Towing the vehicle
Warning!
G
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 ve-
hicle. Adapt your driving accordingly.
!When towing the vehicle with all wheels 
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter 
switch position2, the vehicle doors 
lock if the left front wheel as well as the 
right rear wheel are turning at vehicle 
speeds of approx. 9 mph (15 km/h) or 
more.
Switch off the tow-away alarm 
(page 79).
To prevent the vehicle doors from lock-
ing, deactivate the automatic central 
locking (
page 129).
Towing of the vehicle should only be 
done using the properly installed tow-
ing eye bolt. Never attach tow cable, 
tow rope or tow rod to vehicle chassis, 
frame or suspension parts.
iIf the battery is disconnected or dis-
charged
the SmartKey will not turn in the 
starter switch. See notes on the 
battery (
page 307) or on jump 
starting (page 310).
the gear selector lever will remain 
locked in positionP. See notes on 
manual unlocking of gear selector 
lever (
page 291).
