Notes on care
Regular and proper care maintains the value
of your vehicle.
i It is advisable to use Mercedes-Benz care
products.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
Repair damage caused by loose chippings
and remove the following substances imme-
diately, whilst avoiding rubbing too hard:
R Soak insect remains with insect remover
and rinse off afterwards .
R Soak bird droppings with water and rins e
off afterwards.
R Remove tree resin, oils, fuels and grease by
rubbing gently with a cloth soaked in clean-
ing or lighter fluid .
R Use silicone remover to remove wax.
R Use tar remover to remove tar stains. H
Environmental not
e
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally-responsible manner.
! Do not affix :
R stickers
R films
R magnetic plates or similar
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long perio d
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operatin g
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the very start,!
Do not use high pressure car wash sys-
tems. The strong water jet could damage
painted parts or attachments.
! Do not use a brush-free automatic car
wash that uses chemical agents to wash
the vehicle.
but preferably one without brushes.
If the vehicle is very dirty, prewash it befor e
cleaning it in an automatic car wash.
! 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. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rai n
sensor may otherwise be activated, for
instance, leading to inadvertent wiper
sweeps being triggered. This could cause
damage to the vehicle.
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. Operation

G
Risk of accident
Only have work on the engine electronics
and related components carried out at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The vehicle's roadworthiness could other-
wise be affected.
! Only have work done on the engine elec-
tronics and its associated parts, such as
control units, sensors and connector leads,
carried out at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and the vehicle may
lose its liability for material defects and its
operating permit. Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the emark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
! Damage or consequential damage arising
from fitting equipment not approved
by Mercedes-Benz is not covered under the
Mercedes-Benz liability for materia l
defects.
If you wish to install two-way radios in the
vehicle, you must obtain formal approval.
Mercedes-Benz approves the installation of
two-way radios if such equipment is installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed. G
Risk of accident
Two-way radios may interfere with the vehi-
cle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if: Technical data
