Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a Air vents in the roof
In vehicles with a second cooling system
39) for ventilating the passenger
compartment, an air outlet is fitted in the roof above each rear seat
Ÿfig. 122.
The air outlets in the roof can be opened and closed individually and
adjusted by moving the grid.
Each air outlet has two thumb wheels. The left thumb wheel can be used to
open and close the air outlet. The right thumb wheel can be used to direct the
air towards the head and chest.
WARNING
Never leave objects, food or medicines in front of the air outlets in the rear
seats. The hot air could damage or destroy heat-sensitive objects, food or
medicines.
Caution
Do not use the area in front of the outlets to store objects. This could cause
the blower to overheat and switch off. The blower could also be damaged.
Note
In the cooling mode, at least one air outlet in the roof must be open. The
cooling system could otherwise ice over.
General notes
The pollen filter
The pollution filter serves as a barrier against impurities in the ambient air
(e.g. dust and pollen).
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Instructions for use
If the air conditioning or Climatronic
40) is not switched on for a long period,
deposits on the evaporator can cause unpleasant smells. To prevent these
odours, the cooling system should be run at the highest blower setting at
least once a month when temperatures are over +5°C. Briefly open a window
at the same time.
Faults in the operation of the air conditioning
There is a fault if the all the symbols in the Climatronic flash for approx. 15
seconds when the ignition is switched on. Contact a specialist workshop.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•the engine is not running.
•The blower is switched off.
•The outside temperature is lower than +5°C.
•the cooling system compressor has been temporarily switched off
because the engine coolant temperature is too high.
•The air conditioner fuse is faulty.

•Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.
WARNING
Please note that when the Climatronic is switched off, no fresh air will enter
the vehicle interior. For this reason you should ensure that sufficient fresh
air is able to enter the vehicle by opening a window or the sliding/tilting
sunroof
40) when the Climatronic is switched off.
Caution
•If you suspect that the air conditioner is damaged, switch off the air condi-
tioner with button to prevent further damage and have it checked by a
qualified workshop.
•Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend that you take the vehicle to a quali-
fied workshop should problems occur.
Note
•If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle, this is completely normal and there is no need to suspect
a leak.
•Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling is not impaired, and to prevent the
windows misting over.
•The air conditioning system operates most effectively with the windows
and the sliding /tilting roof 40) closed. However, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•Do not smoke while air recirculation mode is on, as smoke drawn into the
cooling system leaves a residue on the evaporator, producing a permanent
unpleasant odour.

Adjusting the steering wheel position
The height and reach of the steering wheel can be freely
adjusted to suit the driver.
– Adjust the driver seat to the correct position.
– Push the lever under the steering column Ÿfig. 123 down
Ÿ.
– Adjust the steering wheel in this way until the correct position is
set Ÿfig. 124.
– Then push the lever up again firmly Ÿ.
WARNING
•Incorrect use of the steering column adjustment function and an incor-
rect seating position can result in serious injury.
•To avoid accidents, the steering column should be adjusted only when
the vehicle is stationary. Risk of accident.
