PRES. MONITOR

or
TIRE PRES.

CHECK TIRES!


Check the tire inflation pressures and
correct them if necessary.

Reactivate the tire inflation pressure
monitor.
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3 000
to 6 000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure. If nec-
essary, activate the tire inflation pressure
monitor*.Warning!
G
Rotate front and rear wheels only if they are
of the same size.
!If your vehicle is equipped with a tire in-
flation pressure monitor*, there are
electronic components built into the
wheel.
Do not use mounting tools in the area
of the valve as they could damage the
electronic components.
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 ft.lb. (150 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

278 OperationWinter driving
Winter drivingBefore the onset of winter have your vehi-
cle winterized at an authorized
Mercedes-Benz Center. This service in-
cludes:

Check of anticorrosion and antifreeze
concentration.


Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a premixed windshield washer
solvent / antifreeze which is formulated
for temperatures below freezing point
(page 376).


Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to ensure
that the engine can be started even at
low ambient temperatures.


Tire change. We recommend M+S rat-
ed radial-ply tires on all four wheels for
the winter season.
Winter tires
Always use winter tires at temperatures
below 39°F (4°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS, ESP, and 4MATIC
in winter operation.
For safe handling, ensure that all mounted
winter tires are of the same make and have
the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your ve-
hicle, you must place a notice to this effect
where it will be seen by the driver. Such no-
tices are available from your tire dealer or
from any authorized Mercedes-Benz
Center.Warning!
G
Winter tires with a tread depth of less than
0.16 in. (4 mm) must be replaced. They are
no longer suitable for winter operation.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.

279 Operation
Winter driving
Block heater*
(Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at
your authorized Mercedes-Benz Center.
Snow chains
When using snow chains, vehicles with
AIRMATIC should only be driven at raised
vehicle level (
page 212). Vehicles with
ABC* should only be driven at vehicle
height 1 (
page 215).
Snow 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:


Using snow chains is not permissible
with all wheel/tire combinations.


Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.


Use only snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.
iWhen driving with snow chains, you
may wish to deactivate the
ESP (
page 80) before setting the ve-
hicle in motion. This will improve the
vehicle‘s traction.
!Even on vehicles with all-wheel drive,
use snow chains on rear tires only.
Do not use snow chains with tire sizes
245/45 R 18 on 8
1/2 x 18 rims and
265/40 R 18 in general (
page 364).
Do not use snow chains on tires mount-
ed on AMG rims.

iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center
correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.

284 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax should be applied to the engine
compartment after every engine cleaning.
Before applying, all control linkage bush-
ings and joints should be lubricated. The
poly-V-belt and all pulleys should be pro-
tected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently. Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, turn signal
lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of
water, and a KEYLESS-GO* card is in
close proximity, i.e. within approx. 3 ft.
(approx. 1 m), the vehicle could be in-
advertently locked or unlocked.

286 OperationVehicle careWiper blades
Clean the wiper blade inserts with a clean
cloth and detergent solution.Window cleaning
Use a window cleaning solution on all glass
surfaces. An automotive glass cleaner is
