318 OperationWinter drivingSnow chainsSnow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
Please observe the following guidelines
when using snow chains:


Use of snow chains is not permissible
with all wheel/tire combinations
(page 435).


Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.


Only use snow chains that are ap-
proved by Mercedes-Benz. Any autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.


Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.


Do not use snow chains on the spare
wheel (
page 440).


Do not use snow chains on wheels with
MOExtended tires* (
page 439).
!
When driving with snow chains, always se-
lect setting 1 of the level control system
(
page 225). Other settings may result in dam-
age to your vehicle.
!
Some tire sizes do not leave adequate clear-
ance for snow chains. To help avoid serious dam-
age to your vehicle or tires, use of snow chains is
not permissible with


285/35 R18 97W


285/35 R18 97Y


285/35 ZR18 97Y


285/30 ZR19 98Y XL (Extra Load)

If snow chains are mounted to the front
wheels, they may scrape against the body or axle
components. The tires or the vehicle could be
damaged as a result.
i
When driving with snow chains, you may
wish to deactivate the ESP
® (page 91) before
setting the vehicle in motion. This will improve
the vehicle’s traction.

Only use tires which have been tested and
approved by Mercedes-Benz. Tires approved by

possible performance in conjunction with the
driving safety systems on your vehicle such as
ABS or ESP
®. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding the
following on the tire’s sidewall:

For information on driving with MOExtended
tires, see “MOExtended system”(
page 301).
!
Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as


poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the re-
sult.

Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. A placard with the recommended tire in-
flation pressures is located on the driver’s door
B-pillar. Some vehicles may have supplemental
tire inflation pressure information for driving at
high speeds (
page 292) or for vehicle loads
less than the maximum loaded vehicle condition
(
page 292). If such information is provided, it
can be found on the placard located on the in-
side of the fuel filler flap.The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.

The following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Performance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. See an authorized Mercedes-Benz
Center for more information.
