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 Nbefore 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 Nusing the E-SELECT
lever beforehand, it shifts automatically to
parking position Pand 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 127).
! 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.
! Preferably use automatic car washes with
adjustable high-pressure pre-cleaning. This
corresponds with the specification for the
Cabriolet program. In car washes that use
high water pressures, there is a risk that a
small amount of water may leak into the
vehicle.
! Cabriolet: do not treat the vehicle with
hot wax 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.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each
country.

Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz
recommends that you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz. These
batteries provide increased impact
protection to prevent vehicle occupants from
suffering acid burns should the battery be
damaged in the event of an accident.
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the battery
disconnected at a qualified specialist
workshop. You can also charge the battery
with a charger recommended by Mercedes- Benz. Contact a qualified specialist workshop
for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standing idle
for a lengthy period. Consult a qualified
specialist workshop if you wish to leave your
vehicle parked for a long period of time.
i Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conserving battery
power.
i If the battery power supply has been
interrupted, e.g. if the battery was fully
discharged, you will need to reset the
"exterior mirrors automatic folding
function", by folding the mirrors out once
(Y page 88). Charging the battery

ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. G
WARNING
A discharged battery can freeze at
temperatures below freezing point. When
jump-starting the vehicle or charging the
battery, gases can escape from the battery.

WARNING
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the
components on the circuit and their functions
stop operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed 244
