Winter driving
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 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 467).
Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
Only use snow chains that are
approved by Mercedes-Benz. Any
authorized 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 467).
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.!Some tire sizes do not leave adequate clear-
ance for snow chains. To help avoid serious dam-
age to your vehicle or tires, make sure that the
use of snow chains is permissible as specified in
the Technical data section of this Operator’s
Manual, see “Rims and tires” (
page 467).
!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.
iWhen driving with snow chains, you may
wish to deactivate the ESP® (page 63) before
setting the vehicle in motion. This will improve
the vehicle’s traction.
369 Operation
Vehicle care
Cleaning the panorama roof with
tilt/sliding panel*
The rear part of the tilt/sliding panel has a
protective layer on the inside.
Use a soft, clean cloth and a mild
window cleaning solution.
An automotive glass cleaner is recom-
mended.Chrome-plated exhaust tip*
Regular cleaning and care of chrome-plat-
ed exhaust tips will help to maintain their
shine and the classy appearance.Use Mercedes-Benz approved Chrome
Polishing Paste each time the vehicle
has been washed, especially during the
winter.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO*
start/stop button (vehicles with KEYLESS-GO*
(Canada only)).
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.
!To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners con-
taining 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.
!Do not use a dry cloth, abrasives, solvents
or cleaners containing solvents. Do not touch
the protective layer with hard objects such as an
ice scraper or ring. Never apply strong force and
only use a soft, non-scratching cloth when clean-
ing the rear part of the tilt/sliding panel.
Otherwise you may scratch or damage the pro-
tective layer.!Do not use alkaline cleaners such as wheel
cleaners as they could cause corrosion.
370 Operation
Vehicle care
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.Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Wipe with a cloth moistened in a luke-
warm solution.
The surface may temporarily change
color. If this is the case, wait for it to
dry.Hard plastic trim items
Use Mercedes-Benz approved Interior
Care, a soft, lint-free cloth and apply
with light pressure.
!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an
extended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning.
Therefore, the vehicle’s brake system should al-
ways be warmed-up before it is parked after
cleaning. To do so, please drive your vehicle for
several minutes to allow the brakes to dry. When
applying Mercedes-Benz approved Tire Care and
Mercedes-Benz approved Wheel Care products,
take care not to spray them on the brake disks.
Warning!G
Do not use cleaners or cockpit care sprays
containing solvents to clean the cockpit or
the steering wheel. Cleaners containing sol-
vents will make the surface porous and vehi-
cle occupants could suffer serious injuries
from plastic parts coming loose in the event
of air bag deployment.
!Do not use oil, wax or scouring agents on
these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the surface.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the sur-
face.

Lamps in instrument cluster
General information:
If any of the following lamps in the instru-
ment cluster fails to come on during the
bulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow Antilock
Brake System (ABS)
indicator lamp comes on
while the engine is
running.The ABS has detected a malfunction and
has switched off. The BAS, ESP® and EBP
are also switched off (see messages in mul-
tifunction display).
The brake system is still functioning nor-
mally but without the systems specified
above.
If the ABS control unit is malfunctioning,
other systems such as navigation system*
or the automatic transmission* may also be
malfunctioning.
Continue driving with added caution.
Wheels will lock during hard braking, re-
ducing steering capability.
Read and observe messages in the mul-
tifunction display (
page 387).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions
increases the risk of an accident.
