2008 MERCEDES-BENZ CLS COUPE headlamp

Driving abroad
208 Driving on wet roads
If water has accumulated to a certain depth
on
the road surface, there is a danger of aqua-
planing occurring, even if:
R you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully. Driving on flooded roads
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R The

maximum permitted depth in still water
is 25 cm.
R You should drive no faster than at walking
pace.
! Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
You must observe these notes, otherwise
damage may occur to the engine, electrics
and transmission. Driving abroad
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 190). 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.
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 visit a
country

in which traffic drives on the same
side of the road as in the country in which
your vehicle was registered. You may oth- erwise dazzle the oncoming traffic and
could cause an accident.Operation

Care
212
!
Only fold the windscreen wipers away
from the windscreen when vertical, other-
wise you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen until you feel them engage.
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 otherwise the coating may come off.
This could cause 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.
Therefore, 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.
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.
Cleaning the steering wheel boss and
dashboard X
Moisten a clean lint-free cloth with water.
X Clean the plastic parts and the dashboard.
X If particularly dirty, use a mild detergent. G
Risk of injury
Do not use cleaners and cockpit care
sprays containing solvents to clean the
cockpit and steering wheel boss. Cleaners
containing solvents cause the surface to
become porous and in the event of an air- Operation

Troubleshooting
259Headlamps 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. Windscreen wipers
Problem Possible cause/consequence Suggested solutions
The windscreen wipers are jam-
med. Leaves or snow, for example, may
be obstructing the windscreen
wiper movement. The wiper
motor has been deactivated. X
For safety reasons, you should remove the key from the ignition
lock.
X Remove the cause of the obstruction.
X Switch the windscreen wipers back on. The windscreen wipers fail com-
pletely. The windscreen wiper drive is
malfunctioning. X
Select another wiper speed on the combination switch.
X Have the windscreen wipers checked at a qualified specialist work-
shop. Practical advice
