Care
Care and cleaning products
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use only care products and cleaning agents
recommended and approved by Mercedes-
Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
and do not scrub.
Do not touch the surfaces and protective
films with hard objects, e.g. rings or ice
scrapers. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging, cleaning cloths
and polishing wads in an environmentally
responsible manner.
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Exterior care
Automatic car wash G
Risk of accident
The efficiency of the brakes is reduced after
using an automatic car wash. This could cause
an accident. For this reason, following a car
wash, drive with particular care until the
brakes are dry. You can wash the vehicle in an automatic car
wash from the beginning.
!
Do not wash vehicles with an exterior
spare wheel bracket* in an automatic car
wash.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! When washing your vehicle in a tow-
through car wash, make sure that the auto-
matic transmission is in position N, other-
wise the vehicle could be damaged.
R Vehicles with a key:
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
R Vehicles with KEYLESS GO*:
Do not open the driver's or front-
passenger door when the engine is
switched off, as this shifts the automatic
transmission to park position Pand locks
the wheels.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain/light sensor may be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen. Care

High-pressure cleaners
G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to failures or leaks.
Cleaning the paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
X Remove the following types of dirt immedi-
ately, whilst avoiding rubbing too hard.
Soak:
R insect remains with insect remover
R bird droppings with water and rinse off the treated surface after-
wards.
Remove:
R
tree resin, oils, fuels and greases by rub-
bing gently with a cloth soaked in petro-
leum ether or lighter fluid.
R tar stain with tar remover
R wax with silicone remover
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. Otherwise, you could
damage the paintwork.
Cleaning the wheels !
Do not use acidic wheel cleaners to
remove brake dust. This could damage
wheel bolts and brake components.
Cleaning the windows X
Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
product approved and recommended by
Mercedes-Benz.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Under certain circumstances,
deposits such as leaves, petals and pollen
may prevent water from draining away
leading to corrosion damage.
Cleaning the wiper blades G
Risk of injury
Before cleaning the windscreen or wiper
blades, turn the key to position 0in the igni-
tion lock or press the Start/Stop button* until
all indicator lamps have gone out in the instru-
ment cluster. The windscreen wipers could
otherwise move and cause injury. 202

camera lens :.
! Do not clean the camera lens and the area
around the reversing camera with a high-
pressure cleaner.
Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. Reg-
ular care of the exhaust tail pipes will ensure
that their original shine is restored.
!
Do not clean the exhaust tail pipes with
alkaline-based cleaning agents such as
wheel cleaner.
X Clean the exhaust tail pipes with a chrome
care product approved by Mercedes-Benz.

ronmentally-responsible manner. Interior care
Cleaning the steering wheel boss and
dashboard G
Risk of injury
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as a result plastic
parts may break away and be thrown around
the interior when an airbag is deployed which
may result in severe injuries.
X Wipe the dashboard and steering wheel
boss with a damp, lint-free cloth (e.g. a
microfibre cloth) and cleaning agent.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the COMAND display X
Before cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display surface using a commer-
cially-available microfibre cloth and TFT/
LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
! For cleaning, do not use any of the fol-
lowing:
R alcohol-based solvents or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do
not exert pressure when cleaning the dis-
play surface as this may lead to irreversible
damage.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather, artificial leather or 204

X Remove fire extinguisher ;. Vehicle tool kit, TIREFIT, jack and
"Minispare" emergency spare
wheel*
The vehicle tool kit, TIREFIT, jack and
"Minispare" emergency spare wheel are in the
stowage space under the luggage compart-
ment floor. G
Risk of injury
The jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed.
You must use axle stands if you are carrying
out work on the vehicle.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
Otherwise, the jack will not be able to achieve
its load-bearing capacity due to the restricted
height.
Do not start the engine at any time while a
wheel is being changed. Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or if a door or the
tailgate is opened or closed) and you could be
seriously injured.
i When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 262).
X Open the luggage compartment floor
(Y page 208).
