the side windows and the roof are com-
pletely closed R
the climate control blower is switched off R
the windshiel dw iper 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 windshiel da nd 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 speciall ye quipped washing bays.
Observe the legal requirements in each country. X
Do not use hot water and do not wash the
vehicle in direct sunlight. X
Use as oft sponge to clean.X
Use am ild cleaning agent, such as ac ar
shampoo approved by Mercedes-Benz. X
Thoroughly hose down the vehicle with ag en-
tle jet of water. X
Do not point the water jet directly towards the
air inlet. X
Use plenty of water and rinse out the sponge
frequently. X
Rinse the vehicle with clean water and dry
thoroughly with ac hamois.X
Do not let the cleaning agent dry on the paint-
work.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.

G WARNING
The water jet from ac ircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amage dint his way may fail unexpect-
edly .T here is ar isk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged tires or chassis component sr eplaced imme-
diately.
! Alway sm aintain ad istance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information abou tt he
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following: R
Tires R
Door gaps, roof gaps, joints, etc. R
Soft top (Designo retractable hardtop) R
Electrical components R
Battery R
Connectors R
Lights R
Seals R
Trim R
Ventilation slots
Damaged seals or electrical component sc an
lead to leaks or failures.
! Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other com-
ponents.
Cleaning the paintwork
! Do not affix: R
stickers R
films R
magnetic plates or simila ri tems
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit aq ualified specialist workshop. X
Remove dirt immediately ,w here possible,
while avoiding rubbing too hard. X
Soak insect remains with insect remover and
rinse off the treated areas afterwards. X
Soak bird droppings with water and rinse off
the treated areas afterwards. X

Maintenance and care Z

Jump-starting For the jump-starting procedure, use only the jump-starting connection point in the engine com-
partment ,c onsisting of ap ositive terminal and ag round point.
G WARNING
Battery acid is caustic. There is ar isk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the
battery. Keep children away from batteries. Wash away battery acid immediately with plenty of
clean water and seek medical attention.
G WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is ar isk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over ab attery.
G WARNING
During the charging process, ab attery produces hydrogen gas. If as hort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is ar isk of an explosion.R
Make sure that the positive terminal of ac onnected battery does not come into contact with
vehicle parts. R
Never place metal objects or tools on ab attery.R
It is important that you observe the described order of the battery terminals when connecting
and disconnecting ab attery.R
When jump-starting, make sure that the battery poles with identical polarity are connected. R
It is particularly important to observe the described order when connecting and disconnecting
the jumper cables. R
Never connect or disconnec tt he battery terminals while the engine is running.
G WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is ar isk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-
charged battery has frozen .Int his case, you may neither charge the battery nor jump-start the
vehicle. The service life of at hawed-out battery may be shorter. The starting characteristic sc an be
impaired, particularly at low temperatures. Have the thawed-out battery checked at aq ualified
specialist workshop. Jump-starting 249
