347 Operation
Tires and wheels
Rotating tires
Tire rotation can be performed on vehicles
with tires of the same dimension all
around. If your vehicle is equipped with
tires of the same dimension all around,
tires can be rotated, observing a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 320).
In some cases, such as when your vehicle
is equipped with mixed-size tires (different
tire dimension front vs. rear), tire rotation
is not possible.If applicable to your vehicle’s tire configu-
ration, tires can be rotated according to
the tire manufacturer’s recommended in-
tervals in the tire manufacturer’s warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should
be rotated every 3 000 to 6 000 miles
(5 000 to 10 000 km), or sooner if neces-
sary, according to the degree of tire wear.
The same rotation (spinning) direction
must be maintained (
page 320).
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake discs, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.For information on wheel change, see the
“Practical hints” section (
page 388) and
(
page 408).
Warning!
G
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs.
rear), tire rotation is not possible.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
80 lb-ft (110 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

349 Operation
Winter driving
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not higher
than 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.


Snow chains should only be used on
the rear wheels. Follow the manufac-
turer’s mounting instructions.


Only use snow chains that are ap-
proved by Mercedes-Benz. Your 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.
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.
iWhen driving with snow chains, you
may wish to deactivate the ESP
®
(
page 85) before setting the vehicle
in motion. This will improve the vehi-
cle’s traction.
!Some tire sizes do not leave adequate
clearance for snow chains. To help
avoid serious damage to your vehicle or
tires, use of snow chains is not permit-
ted with the collapsible tire and
MOExtended tires in general, and/or
the following tire sizes:

225/45 R17


245/40 R17


225/40 ZR18 92Y XL (Extra Load)


245/35 ZR18 92Y XL (Extra Load)

fully raised and closed.
Use a clean cloth and window cleaning
solution on all outside and inside glass
surfaces.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.

Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.
!To clean the window interior, do not
use a dry cloth, abrasives, solvents or
cleaners containing solvents. Do not
touch the inside of the front, rear or
side windows with hard objects such as
an ice scraper or ring. Doing so may
damage the windows.!Fold the windshield wiper arms back
onto the windshield before turning the
SmartKey in the starter switch.
Hold on to the wiper when folding the
wiper arm back. If released, the force
of the impact from the tensioning
spring could crack the windshield.

362 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on ignition
(
page 36), have the respective bulb
checked and replaced if necessary.
Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp comes on
while driving.
The ABS has detected a malfunction
and has switched off. The BAS and
ESP
® are also switched off (see mes-
sages in display).
The brake system is still functioning
normally but without the ABS avail-
able.
If the ABS control unit is malfunction-
ing, other systems such as the
automatic transmission* may also be
malfunctioning.

Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.

Read and observe messages in the
multifunction display (
page 368).

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched
off.
The battery might not be charged suf-
ficiently.

Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.

If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.

368 Practical hintsWhat to do if …Vehicle status messages in the multifunction display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 132) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset buttonJ (
page 24) or
buttonj, k, ·, orè on the
steering wheel.
Other high-priority messages and messag-
es of less immediate priority (regular dis-
play colors) can be cleared from the
multifunction display using the reset
buttonJ (
page 24) or buttonj,
k, ·, orè on the steering
wheel. They are then stored in the vehicle
status message memory (
page 132). Re-
member that clearing a message will only
make the message disappear. Clearing a
message will not correct the condition that
caused the message to appear.
Warning!
