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.
GWarning!
After washing the vehicle, braking efficiency
may be reduced. Reduced braking efficiency
could cause an accident.
Brake the vehicle significantly after washing
the vehicle. Observe the traffic situation when
doing so. The brake discs will warm up and
dry faster. Drive carefully after washing the
vehicle until the brakes have dried and you
can notice that brake efficiency has been
restored.
Hand-washXDo not use hot water or wash your vehicle
in direct sunlight.XOnly use a soft, wet cloth or sponge to
clean the vehicle.XOnly use a mild vehicle wash detergent,
such as Mercedes-Benz approved Car
Shampoo.XThoroughly spray the vehicle with a
diffused jet of water.XDo not spray directly towards the
ventilation intake.XUse plenty of water and rinse the sponge
and chamois frequently.XRinse with clean water and dry with a
chamois thoroughly.
Do not allow cleaning agents to dry on the
finish.
Automatic car wash
You can have your vehicle washed in an
automatic car wash from the start. Brushless
car washes are preferable.
XTo protect the filter system, activate the air
recirculation mode using button 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.XWhen taking the vehicle through an
automatic conveyor-type car wash:
Make sure the transmission remains in
neutral position N. Observe instructions,
see “Shifting into neutral position N”
( Y page 263).
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldings
XFor regular cleaning and care of ornamental
moldings, use a damp cloth.
! Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings
may have chrome appearance, they could
be made of anodized aluminum that will be
damaged when cleaned with chrome
cleaner. Instead, use a damp cloth to clean
those ornamental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated, use
a chrome cleaner. If in doubt whether an
ornamental molding is chrome-plated,
contact an authorized Mercedes-Benz
Center.
Lamp lenses
XUse a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
! Only use window cleaning solutions that
are suitable for plastic lamp lenses.
Window cleaning solutions which are not
suitable may damage the plastic lamp
lenses of the headlamps. Therefore, do not
use abrasives, solvents or cleaners that
contain solvents.
Cleaning the Parktronic system sensors
Parktronic system sensors are located in the
front and rear bumper.
XOnly clean Parktronic system sensors :
by hand.XUse a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water and a soft, non-
scratching cloth to clean Parktronic system
sensors : on the bumpers.

GWarning!
Do not exceed a vehicle speed of 50 mph
( 80 km/h). A TIREFIT repair is not designed to
operate at higher speeds.
The sticker must be attached on the
instrument cluster where it will be easily seen
by the driver.
Vehicle handling characteristics of a TIREFIT
repaired tire may change. Adapt your driving
accordingly.
XAfter driving for approximately 5 miles
(3 km) or 10 minutes, stop the vehicle and
check the tire inflation pressure using the
electric air pump.
i The TIREFIT sealing may impair the
function of the sensors in the tire. Proper
operating sensors are necessary to check
the tire inflation pressure with the
Advanced Tire Pressure Monitoring
System. When the sensors are not
operating properly, the measured tire
inflation pressure may be inaccurate or the
tire inflation pressure may not be displayed
at all. Error messages may appear.
Therefore, check and adjust the tire
inflation pressure with pressure gauge B
on the electric air pump.
GWarning!
If tire inflation pressure has fallen below
130 kPA (1.3 bar, 20 psi) do not continue to
drive the vehicle.
Park your vehicle safely away from the
roadway and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
Have the damaged tire replaced.
If the tire inflation pressure is at least 130 kPA
(1.3 bar, 20 psi), inflate or deflate the tire to
the correct tire inflation pressure (see Tire
and Loading Information placard on the
driver’s door B-pillar):XTo increase tire inflation pressure:
Switch on the electric air pump.XTo decrease tire inflation pressure:
Open vent screw C on air hose E.XDrive to the nearest qualified workshop,
e.g. an authorized Mercedes-Benz Center,
to have the damaged tire replaced.XContact an authorized Mercedes-Benz
Center as soon as possible to obtain a new
