Lights and visibility
WARNING
Fold and unfold the exterior mirror, taking care to avoid injuries.
● Only fold or unfold the exterior mirror when there is no-one in the way
of the mirror.
● When moving the mirror, take care not to trap fingers between the
mirror and the mirror bracket.
WARNING
Failure to correctly estimate the distance of the vehicle behind could lead
to serious accident.
● Rear-view convex or aspheric mirrors increase the field of vision, how-
ever objects appear smaller and further away in the mirrors.
● The use of these mirrors to estimate the distance to the next vehicle
when changing lane is imprecise and could result in serious accident.
● If possible, use the rear vision mirror to estimate distances to vehi-
cles behind you or in other circumstances.
● Make sure that the rear visibility is adequate.
CAUTION
● Before entering a car wash, always ensure that the exterior mirrors are
correctly folded in.
● Electrically-folding exterior mirrors should not be folded and unfolded
mechanically as this may damage the electrical operation.
For the sake of the environment
The exterior mirror heating should be switched off when it is no longer nee-
ded. Otherwise, it is an unnecessary fuel waste.
Note
● The exterior mirror heating initially heats up with a high power, after two
minutes the heat will depend upon the ambient temperature.
● In the event of faults, the electric exterior mirrors can be adjusted man-
ually by pressing the edge of the mirror surface.

Never close the air vents ⇒ Fig. 125 A
completely to ensure heating, cool-
ing and ventilation inside the vehicle.
● Turn the thumbwheel in the required direction to open and close the air
vents. When the thumbwheel is in the position, the corresponding air vent
is closed.
● Change the air direction using the ventilation grille lever.
There are other air vents that cannot be adjusted on the dash panel B
, in
the footwell and in the rear area of the interior.
CAUTION
Never place food, medicines or other heat-sensitive objects close to the air
vents. Food, medicines and other heat-sensitive objects may be damaged
or made unsuitable for use by the air coming from the air vents.
Note
The air from the vents flows through the vehicle interior and out through the
outlets below the rear window. The slots must not be covered with items of
clothing or other objects.
Air recirculation mode
Air recirculation mode prevents the ambient air from entering the interior.
When the outside temperature is very high, selecting manual air recircula-
tion mode for a short period refreshes the vehicle interior more quickly.
For safety reasons, air recirculation mode is switched off when the
button is pressed or the air distributor turned to ⇒

Automatic air recirculation mode
Fresh air enters the vehicle interior in position . If the system detects a
high concentration of hazardous substances in the ambient air, air recircu-
lation mode is switched on automatically. When the level of impurities
drops to within a normal range, recirculation mode is switched off.
The system is unable to detect unpleasant smells.
With the following outside temperatures and conditions the air recirculation
does not switch on automatically:
● The cooling system is switched on (the AC
button is lit up) and the out-
side temperature is below +3 °C (+38 °F).
● The cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).
● The cooling system is switched off and the outside temperature is below
+15 °C (+59 °F). The windscreen wiper is switched on.
Switching the automatic air recirculation mode on and off
Switching on: Press the button until the right lamp on the button lights
up.
Switching off: Press the button until all the lamps on the button are

Press the button once to temporarily switch to manual air recircula-
tion mode in the event of unpleasant smells from outside. The left indicator
lamp turns on.
● After more than two seconds, press the button again to restart auto-
matic air recirculation. The right indicator lamp turns on.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is not required.
CAUTION
Do not smoke when air recirculation is switched on in vehicles with an air
conditioner. The smoke taken in could lie on the cooling system vaporiser
and on the activated charcoal cartridge of the dust and pollen filter, leading
to a permanently unpleasant smell.
Note
Climatronic: Air recirculation mode switches on to prevent exhaust gas from
entering the vehicle interior when it is in reverse and while the automatic
windscreen wash and wipe is working.
