normally be done every 3 to 5 months,
depending on the climate and washing
detergent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface shows
signs of embedded dirt (i.e. loss of gloss).
Do not apply any of these products or wax if
your
vehicle
is parked in the sun or if the hood
is still hot.
X Use the appropriate MB-Touch-Up Stick for
quick and

provisional repairs of minor paint
damage (i.e. chips from stones, vehicle
doors, etc.).
Engine cleaning Prior to cleaning the engine compartment,
make sure to protect electrical components
and connectors from contact with water and
cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax should be applied to the
engine compartment after every engine
cleaning. Before applying, all control linkage
bushings
and

joints should be lubricated. The
poly-V-belt and all pulleys should be
protected from any wax.
Vehicle washing In the winter, thoroughly remove all traces of
road salt as soon as possible.
When
washing

the vehicle underbody, do not
forget to clean the inner sides of the wheels.
i Vehicles with KEYLESS-GO:
If a door handle is hit by a strong jet of
water, and a SmartKey is within
approximately 3 ft (1 m) of the vehicle, it
could be inadvertently locked or unlocked.
Hand-wash
X Do not use hot water or wash your vehicle
in direct sunlight.
X Only use a soft, wet cloth or sponge to
clean the vehicle. X
Only use a mild vehicle wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
X Thoroughly spray the vehicle with a
diffused jet of water.
X Do not spray directly towards the
ventilation intake.
X Use plenty of water and rinse the sponge
and chamois frequently.
X Rinse with clean water and dry with a
chamois thoroughly.
Do not allow cleaning agents to dry on the
finish.
Automatic car wash G
Warning!
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function or DISTRONIC
PLUS before the vehicle is washed in an
automatic car wash.
You can have your vehicle washed in an
automatic car

wash from the start. Brushless
car washes are preferable.
X To protect the filter system, activate the air
recirculation mode using rocker switch
g on the climate control panel.
! Do not

clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting $. Otherwise, the rain
sensor could activate and cause the wipers
to move unintentionally. This may lead to
vehicle damage.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors. Vehicle care

Cleaning the windows and the wiper
blades
!
The windshield wipers must be in a
vertical position before folding them away
from the windshield. They could otherwise
damage the hood.
Never open
the hood when the wiper arms
are folded forward.
X Make sure the hood is fully closed.
X Switch on the ignition.
X Turn combination switch to wiper setting
° (Y page 280).
X With wiper arms in vertical position, switch
off the ignition. G
Warning!
For safety reasons, switch off wipers and
remove SmartKey from starter switch before
cleaning the windshield and/or the wiper
blades. Vehicles with KEYLESS-GO: Make
sure the vehicle’s on-board electronics have
status 0. Otherwise, the wiper motor could
suddenly turn on and cause injury.
! Do not pull on the wiper blade inserts.
They could tear.
X Fold the wiper arms forward until they snap
into place.
X Clean the windshield and the wiper blade
inserts with a clean cloth and mild
detergent solution.
X Use a soft, clean cloth and a mild window
cleaning solution on all outside and inside
glass surfaces.
An automotive glass cleaner is
recommended.
! 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.
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
containing solvents. Do not touch the
inside of the windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
Light alloy wheels If possible, clean wheels once a week.
X
Use Mercedes-Benz approved Wheel Care,
a soft bristle brush and a strong spray of
water for cleaning the light alloy wheels.
! 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. This applies especially
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 vehicle is not driven after
cleaning.
Therefore, the vehicle’s brake system
should always be warmed-up before it is
parked after cleaning. 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. 408

Plastic and rubber parts
X
Use a gentle dishwashing detergent or mild
detergent for
delicate fabrics as a washing
solution.
X 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. G
Warning!
Do not use cleaners or cockpit care sprays
containing solvents

to clean the cockpit or the
steering wheel. Cleaners containing solvents
will make the surface porous and vehicle
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.
Otherwise you may scratch or damage the
surface.
Hard plastic trim items
X Use Mercedes-Benz approved Interior Care
on a

soft, lint-free cloth and apply with light
pressure.
COMAND display !
You must
switch off the COMAND display
and allow it to cool prior to cleaning.
! Do not use any liquids or cleaning agents.
These can damage or even destroy the
COMAND display screen.
X Use a standard microfiber cloth and apply
with light pressure.
Steering wheel X
Wipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved
Leather Care. Carpets X
Use Mercedes-Benz approved Carpet and
Fabric Care for cleaning the carpets.
Headliner and shelf below rear window X
Use a soft bristle brush or a dry-shampoo
cleaner in case of excessive dirt.
Seat belts X
Only use clear, lukewarm water and soap.
! The seat belts must not be treated with
chemical cleaning agents. Do not dry the
seat belts at temperatures above 176‡
(80†) or in direct sunlight. G
Warning!
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
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
discolored. By lining the seats with a proper
intermediate
cover,

contact-discoloration will
be prevented. G
Warning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability.
Leather upholstery
Please note 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. Vehicle care

wood trims in your vehicle.
! Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as
these may be abrasive.
Chrome-plated exhaust tip Regular cleaning and care of chrome-plated
exhaust tips will help to maintain their shine
and the classy appearance.
X
Use Mercedes-Benz approved Chrome
Polishing Paste each time the vehicle has
been washed,

especially during the winter.
! Do not use alkaline cleaners such as
wheel cleaners as they could cause
corrosion. 410
