To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
! When the rear bench seat is folded
forwards, the front seats cannot be moved
to their rearmost position. You could
otherwise damage the seats and the rear
bench seat.
! Make sure that the sun visor is folded up
before adjusting the backrest and head
restraint height. The head restraint and sun
visor could otherwise collide when the head
restraint is fully extended.
i If the front door is open, the seats can be
adjusted for up 30 minutes after the
ignition has been switched off.
i The rear-compartment head restraints
can be removed ( Y page 88).
For more information, contact a qualified
specialist workshop.

procedure before setting the vehicle in
motion. All steering wheel adjustment must
be completed before setting the vehicle in motion. Driving off with the steering wheel
still adjusting could cause the driver to lose
control of the vehicle.
! Do not activate the EASY-ENTRY/EXIT
feature,
if the seat backrest is reclined too
far backwards. This can damage the front
or rear seats. You must first move the
backrest to a vertical position.

Exterior care
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, you must drive particularly
carefully after washing the vehicle until the
brakes have dried.
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
! 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. The exterior mirrors could
otherwise be damaged.
! Make sure that the automatic
transmission is in position N when washing
your vehicle in a tow-through car wash. The
vehicle could be damaged if the
transmission is in another position.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (airflow control is turned to
position 0/the à and Á buttons
are switched off).
R the windshield wiper switch is at position
0.
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the
windshield. Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in all
countries concerned.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
When washing the vehicle underbody, also
clean the inside of the wheels.
X
Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlets.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the
paintwork.
Power washers G
WARNING
Do not use power washers with circular jet
nozzles (concentrated-power jets) to clean
your
vehicle, especially for cleaning tires. You
could otherwise damage the tires and cause
an accident.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle. Care
