sand:
R shift the transfer case to
LOW (Ypage 92).
R avoid high engine speeds.
R select a shift range appropriate to the ter-
rain.
R drive quickly to overcome the rolling resist-
ance. Otherwise, the vehicle could dig itself
into the sand.
R drive in the tracks of other vehicles, if pos-
sible. Make sure that the ruts are not too
deep, that the sand is firm enough and that
your vehicle has sufficient ground clear-
ance. Ruts
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel:
! Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
R shift the transfer case to
LOW (Ypage 92).
R avoid high engine speeds.
R select shift range 1.
R drive slowly.
R where ruts are too deep, drive with the
wheels on one side on the middle section
of the road if possible. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain the relevant workshop directories
from any Mercedes-Benz Service Centre.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 154). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. Oncoming traf-
fic will be dazzled less. G
Risk of injury
Xenon bulbs are under high voltage. You
could get an electric shock and be seriously
or even fatally injured if you touch the elec-
tric contacts on xenon bulbs. Therefore, do
not, remove the cover on xenon bulbs.
Do not change xenon headlamps yourself,
but have them replaced at a qualified spe- Operation

Trailer towing*
178 cialist 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
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Have your headlamps switched back to
asymmetrical dipped beam if you are driv-
ing in a country in which traffic drives on
the same side of the road as in the country
in which your vehicle was registered. Oth-
erwise, you may dazzle the oncoming traffic
and could cause an accident. Trailer towing*
Notes on towing a trailer
G
Risk of accident
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar nose-
weight
R the permissible trailer load
R the permissible rear axle load of the tow-
ing vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the
vehicle documents.
You will find the values approved by the
manufacturer on the vehicle identification plates and those for the towing vehicle in
the "Technical data" section.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 274).
The maximum permissible trailer drawbar
noseweight on the ball coupling is:
R 140 kg (long-wheelbase station wagon)
R 115 kg (short-wheelbase station wagon
and cabriolet)
However, the actual noseweight must not
exceed the value given on the trailer coupling
and trailer identification plates. The lowest
weight applies.
! Use a drawbar noseweight as close as
possible to the maximum permissible nose-
weight. Do not use a noseweight of less
than 80 kg; otherwise, the trailer may come
loose.
Note that the payload and the rear axle load
are reduced by the actual payload.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw-
bar. Operation

Care
184
Cleaning the wiper blades and the out-
side of the windscreen G
Risk of injury
Before cleaning the windscreen or wiper
blades, turn the key in the ignition lock to
0. The windscreen wipers could otherwise
move and cause injury.
X Turn the key to position 1in the ignition
lock (Y page 59).
X Set the windscreen wipers to position Ion
the combination switch (Y page 82).
X Turn the key to position 0or remove it when
the wiper arms are vertical (Y page 59).
! Only fold the wiper arms away from the
windscreen when they are in a vertical posi-
tion, otherwise you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen until you feel them snap into place.
X Clean the windscreen and the wiper blades.
X Fold the windscreen wipers back again
before the ignition is switched on.
! Do not clean the wiper blades too often
as this will result in the rubber becoming
porous, leading to wiper noise. Cleaning the windows !
Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Clean the insides of the windows with a
damp cloth or commercially-available glass
cleaner. Avoid touching the inside of the
rear windscreen and the side windows with
hard objects, e.g. ice scrapers or rings. You
could otherwise cause damage to the win-
dows, rear window heating or aerial on the
rear window.
i Anti-glare film retrofitted to the insides of
the windows could interfere with radio or
mobile phone reception, especially if it is
conductive or metal-coated film. Informa-
tion about anti-glare film can be obtained
from any Mercedes-Benz Service Centre.
Cleaning the headlamps X
Clean the headlamp lenses with a wet
sponge.
! Only use washer fluid which is suitable
for plastic lenses. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps.
Do not use the following: R
dry cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvent
You could otherwise scratch or damage the
surface of the lenses.
Plastic trim !
Do not use dry, coarse or hard cloths and
do not scrub. Doing so will scratch or dam-
age the surfaces.
! In order to protect the vehicle's high-qual-
ity surfaces and to retain the overall
appearance, avoid contact with cosmetics
and suntan lotion.
X Wipe plastic parts with a damp, lint-free
cloth (e.g. a microfibre cloth).
X Light soiling: use a low-foaming soap (e.g.
a light liquid hand soap) diluted in water.
X Heavy soiling: use a cleaning agent that is
solvent-free and non-corrosive. Mercedes-
Benz recommends that you use a
Mercedes-Benz cleaning product for this
purpose. Operation

Troubleshooting
223Problem Possible cause/consequence Suggested solutions
You hear a warning signal when
reversing. The ultrasonic reversing aid sen-
sors are dirty or there is interfer-
ence. X
Clean the ultrasonic reversing aid sensors (Y page 186).
X Switch the ignition back on. The problem ma
y be caused by an
external source of radio or ultra-
sound waves. The ultrasonic
reversing aid is switched off. X
See if ultrasonic reversing aid functions in a different location. You hear a warning tone when
reversing or you do not hear a
warning tone and none of the seg-
ments light up. The ultrasonic reversing aid has
malfunctioned and has switched
itself off. X
Have the ultrasonic reversing aid checked at a qualified specialist
workshop as soon as possible. Headlamps and turn signals
Problem Possible cause/consequence Suggested solutions
The headlamps or the turn signals
in the exterior mirrors are misted
up on the inside. Air humidity is very high. X
Drive with the headlamps switched on.
The headlamps are demisted after a short distance. The headlamp housing is not
sealed and moisture has been
able to enter. X
Have the headlamps checked at a qualified specialist workshop. Practical advice
