with air dehumidification function
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
G
WARNING
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and not a sign that
there is a malfunction.
Depending on the equipment level, the con-
trol panel has either the Ábutton or the

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents.T his could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents.K eep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the bonnet and
in the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i You can move the adjuster sfor the air
vents vertically or horizontally, to set the
direction of the airflow.
i Optimal climate control function is ach-
ieved by opening the air vents fully and set-
ting the adjusters to the middle position. 122

or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain further informa-
tion about this from your Mercedes-Benz
Service Centre. Tyre traction
G
WARNING
Whereas the vehicle can be fully controlled at
a certain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. You could otherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), a thin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Drive with particular care in
such weather conditions. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R
you are driving 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 permissible still water depth
is 12 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.
These notes must be observed under all
circumstances. You could otherwise dam-
age the engine, the electronics or the trans-
mission. Winter driving
Important safety notes G
WARNING
If the vehicle becomes trapped in snow,
ensure that snow is kept away from the
exhaust pipe and from around the vehicle as
long as the engine is running. Otherwise, poi-
sonous carbon monoxide (CO) may enter the
vehicle, resulting in loss of consciousness and
even death.
To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 288).
Driving with summer tyres Observe the notes in the "Winter operation"
