Start the engine using the SmartKey.. Move
the transmission to Nwith the E-SELECT
lever. Use the SmartKey to switch the
engine off again and then turn the
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 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 131).
! 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 and the roof are
completely closed
R the climate control blower is switched off
R the windshield wiper switch is at position
0
The vehicle could otherwise 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.

Using the TIREFIT kit TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up
to 0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside
temperatures down to
Ò4 ‡ (Ò20 †). G
WARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown
assistance, as it is unable to seal the tire
properly:
R there are cuts or punctures in the tire larger
than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tire pressures
or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop. G
WARNING
The tire sealant is harmful and causes
irritation. It must not come into contact with
your skin, eyes or clothing or be swallowed.
Do not inhale TIREFIT fumes. Keep tire sealant
away from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
R Rinse off the tire sealant from your skin
immediately with water.
R If the tire sealant comes into contact with
your eyes, immediately rinse them
thoroughly with clean water.
R If tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tire sealant.

! You should have all work involving the
battery carried out at a qualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery
yourself, make sure that:
R you switch off the engine and remove the
SmartKey. On vehicles with KEYLESS-

Fire, open flames and smoking are
prohibited when handling the
battery. Avoid creating sparks. Battery acid is caustic. Avoid
contact with skin, eyes or clothing. Wear suitable protective clothing,
especially gloves, apron and
faceguard.
Rinse any acid spills immediately
with clear water. Contact a
physician if necessary. Wear eye protection.
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.

Important safety notes
G
WARNING
The rear axle locks when:
R the engine is not running
R the engine stalls while the vehicle is being
towed
R there is a malfunction in the power supply
or the vehicle's electrical system
There is a risk of an accident.
In the event of a breakdown, you should
always have the vehicle transported. G
WARNING
If the brake system or power steering is
malfunctioning and your vehicle is then towed
away, significantly more effort may be
required to steer and brake than is normally
required. There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could
rollover.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the
permissible gross weight of your vehicle. !
Use the SmartKey instead of the Start/
Stop button when towing the vehicle.
Start the engine and keep it running. Turn
the SmartKey to position 2in the ignition.
Set the transmission to Nusing the E-
SELECT lever. Make sure that you then
leave the SmartKey in position 2.
Check the transmission position in the
instrument cluster.
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
Mercedes-Benz recommends that you use
an authorized Mercedes-Benz Center for
this purpose.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eyes for recovery
purposes as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
! The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
! Do not tow with sling-type equipment.
This could damage the vehicle. 242

WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, the electric cables could be
overloaded. This could result in a fire. There
is a risk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
! 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 244
