Vehicle care
Use a soft, clean cloth and a mild win-
dow 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.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
lukewarm solution.
The surface may temporarily change
color. If this is the case, wait for it to
dry.
!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*).
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 and the power
tilt/sliding sunroof* or rear panorama roof with
hard objects such as an ice scraper or ring.
Doing so may damage the windows.
!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an ex-
tended 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 always 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.

Vehicle care
Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.Leather upholstery*
Please not that leather upholstery is a
natural product and is therefore subject to
a natural aging process. Leather
upholstery may also react to certain
ambient influences such as high humidity
or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.MB Tex upholstery
Use Mercedes-Benz approved Interior
Care onto a soft, lint-free cloth and
apply with light pressure for cleaning
the upholstery.
Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent
deployment of the front side impact air
bags
deployment of the rear side impact air
bags*
activation of the active head restraints
Contact an authorized Mercedes-Benz Light
Truck Center for availability.
!To avoid damage to leather upholstery:
Wipe with light pressure only.
Do not clean with abrasive cleaning agents
such as scouring milk or powder.
Do not soak the leather upholstery.
As leather is a natural product, it could
otherwise harden or become porous.
Exercise particular care when cleaning
perforated leather as its underside should
not become wet.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as these
may be abrasive.

Rims and tires
!Only use tires which have been tested and
approved by Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to provide best
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:
MO = Mercedes-Benz Original equipment
tires
Using tires other than those approved by
Mercedes-Benz may result in damage that is not
covered by the Mercedes-Benz Limited
Warranty.
!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
result.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz Light
Truck Center. A placard with the recommended
tire inflation pressure is located on the driver’s
door B-pillar (
page 550). Some vehicles may
have supplemental tire inflation pressure infor-
mation for driving at high speeds (
page 394)
or for vehicle loads less than the maximum
loaded vehicle condition (
page 394). If such
information is provided, it can be found on the
placard located on the inside 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.
iThe following pages also list the approved
wheel rim and tire sizes for equipping your
vehicles with winter tires. Winter tires are not
available as standard or optional factory equip-
ment, but can be purchased from an authorized
Mercedes-Benz Light Truck Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire
configuration on your vehicle (Appearance
Package, etc.), equipping your vehicle with win-
ter 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
Light Truck Center for more information.
