matic climate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automati ccli-
mate control.
R Activate climate control using the Ãand
¿ buttons .The indicator lamps above
the à and¿ buttons light up. You
can also set the airflow and air distribution
of the automatic climate control to one of
three levels (FOCUS/MEDIUM/DIFFUSE).
You can set the desired level using button
G.T he MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly,
until the windscreen is clear again.
R Only use the air-recirculation mode briefly,
e.g. if there are unpleasant outside odours
or when in a tunnel. The windows could
otherwise mist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system
Switching climate control on/off
Important information i
When climate control is switched off, the
air supply and air circulation are also
switched off. Only select this setting briefly. Otherwise, the windows may mist
up.

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 prevent you from
observing the traffic conditions, thereby caus-
ing an accident. Operating the climate control system

same for all control panels. G
WARNING
Only switch over to air-recirculation mode
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.

WARNING
Make sure that nobody can become trapped
between the side window and the door frame
as the side windows are opened and closed.
Make sure that all object sand body parts are
clear of the side windows when they are being
opened or closed .You or the objects could be
drawn in or become trapped between the side
window and the door frame as the window
moves. If there is arisk of entrapment, oper-
ate the Wswitch to move the side window
in the opposite direction.
Make sure that nobody can become trapped
as the sliding sunroof/panorama sliding sun-
roof is opened and closed. If there is a risk of
entrapment, operate the 3switch to move

Tyre traction
G
WARNING
Whereas the vehicle can be fully controlled at
a certain speed on dry roads, you must reduce
your speed on we toricy 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 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
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.
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
page 364).
Slippery road surfaces G
WARNING
Do not shift down for additional engine brak-
ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
