Risk of accident
Clear all windows of ice or snow before setting
off. Otherwise, impaired visibility could
endanger you and others.
The rear window heating has ahigh current
draw. You should therefore switch it off as
soon as the window is clear, as it only
switches off automatically after several
minutes. If the battery voltage is too low, the rear win-
dow heating may switch off.

tion mode
You can deactivate the flow of fresh air if
unpleasan todours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.

briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.

matic climate control.
It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off .The heating
time depends on the temperature that has
been set.

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
Risk of accident
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 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 still water depth 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.
These notes must be observed under all
circumstances. You could otherwise dam-
age the engine, the electronics or the trans-
mission. Winter driving
General notes G
Risk of poisoning
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.
At the onset of winter, have your vehicle win-
terproofed at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre.
Observe the notes in the "Winter operation"
section .
