If you have problems when programming the
integrated remote control, please note the
following:
R check the transmitter frequency of garage
door remote control A(which can usually
be found on the back of the remote con-
trol).
The integrated remote control is compati-
ble with devices that have units which oper-
ate in the frequency range of 280 to
390 MHz.
R Replace the batteries in garage door
remote control A.This increases the prob-
ability of garage door remote control A
sending a strong and more precise signal
to the integrated remote control on the
rear-view mirror.
R when programming, hold garage door
remote control Aat varying distances and
angles from the transmitter button which
you are programming. Try various angles at
a distance between 5and 30 cm or at the
same angle but at varying distances.
R if there is another garage door remote con-
trol for the same device, perform the pro-
gramming steps again using that garage
door opener. Before performing these steps, make sure that new batteries have
been fitted in the garage door remote con-
trol.

after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosio
nofthe brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. Care of the exterior
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry.
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This
corresponds with the specifications for
cabriolet programmes. 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.
! 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 other-
wise be damaged.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle 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/theÃandÁ buttons
are switched off).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen.
High-pressure cleaning equipment G
WARNING
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.
! Always maintain a distance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R soft top (Cabriolet)
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 leaks or failures. 296
CareMaintenance and care

In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Avoid the creation of sparks and
heat.
Avoid fire, naked flames and smok-
ing. Creation of sparks.
Battery acid is caustic.
Avoid contact with the skin, eyes
or clothing.
Wear eye protection.
Keep childre
naway. Observe this Owner's Manual.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at a qualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, please contac taquali-
fied specialist workshop.
Explosive gases are created during charging
and jump-starting.
For safety reasons, Mercedes-Benz recom-
mends 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 vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
Have the battery charge checked more fre-
quently 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 up for a long period of time.
i
When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power.
i If the power supply has been interrupted,
e.g. due to a discharged battery, you will
have to:
R set the clock. Information on setting the
clock can be found in the separate oper-
ating instructions.
On vehicles with COMAND Online and a
navigation system, the clock is set auto-
matically.
R reset the head restraints on the front
seats (Y page 93).
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 100). Charging the battery
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
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. Battery (vehicle)
