any necessary additional maintenance work
to be performed.
You can obtain further information from an
authorized Mercedes-Benz Center.
The service interval display does not take into
account any periods of time during which the
battery is disconnected.

222MaintenanceMaintenance and care
SmartKey to position 2. Make sure that you
then leave the SmartKey in position 2. You
may otherwise damage the vehicle, the
transmission or the car wash.
Check the transmission position in the
instrument cluster.
! Use the E-SELECT lever to shift the
transmission to N before switching the
engine off. If you open the driver's or front-
passenger door, the transmission remains
in this position for up to 30 minutes if the
SmartKey is in the ignition, even if the
engine is switched off. If you do not shift
the transmission to N using the E-SELECT
lever beforehand, it shifts automatically to
parking position P and locks the wheels if
the driver's or front-passenger door is
opened and the engine is switched off. This
may damage the vehicle, the transmission
or the car wash.
Observe the information on maneuvering
( Y page 129).
! Before driving into an automatic car wash,
make sure that it is suitable for the
dimensions of the vehicle. In particular,
make sure that:
R there is enough ground clearance
between the vehicle underbody and the
guide rails of the automatic car wash.
R the clearance width of the automatic car
wash is sufficient, particularly the width
of the guide rails.
R you enter the automatic car wash
straight and in the center of the guide
rails in order to avoid damaging the tires
or wheel rims.
Fold in the exterior mirrors before the
vehicle is washed. The exterior mirrors
could otherwise be damaged.
! Make sure that:R
the side windows are fully closed.
R the ventilation/heating is switched off
(the OFF button has been pressed/the
airflow control is set to position 0).
R that the windshield wiper switch is in
position 0.
Otherwise, the vehicle might be damaged.
! In portal car washes, the windshield
wipers may be moved up the windshield by
the cleaning brushes when the ignition is
switched off.
Set the Start/Stop button to key position
2 to reset the windshield wipers to their
original position.
! Vehicles with a matte finish:
Do not use wash programs with a hot wax
treatment under any circumstances.
After using an automatic car wash, wipe off
wax and drying agents from the windshield
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windshield.
Power washersGWARNING
Using power washers with circular-jet nozzles
(dirt grinders) may cause damage to the
vehicle, in particular to the tires.
Using damaged tires results in an increased
risk of accident. A sudden loss of tire pressure
while you are driving may cause you to lose
control of your vehicle, cause an accident and
injure yourself and others.
! Maintain a minimum distance of
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.

interrupted, e.g. if the battery has been
reconnected, you must reset the function
for automatically folding the exterior
mirrors in/out by folding the mirrors out
once ( Y page 90).

Charging the batteryGWARNING
Never charge a battery still installed in the
vehicle unless a battery charger unit approved
by Mercedes-Benz is being used. Gases may
escape during charging and cause explosions
that may result in paint damage, corrosion or
personal injury.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for further
information and availability.
Charge the battery in accordance with the
separate instructions for the battery charger.
GWARNING
There is a risk of acid burns during the
charging process due to the gases which
escape from the battery. Do not lean over the
battery during the charging process.
GWARNING
Battery acid is caustic. Avoid contact with the
skin, eyes or clothing.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged
while still installed.
! Only use battery chargers with a
maximum charging voltage of 14.8 V.
XOpen the hood ( Y page 218).XRead the battery charger's operating
instructions before charging the battery.XConnect the battery charger to the positive
