Heating, Ventilation and Air conditioning 156
The Climatronic can be fitted either with or without an additional cooling
system 38) for the passenger compartment.
Climatronic for the passenger compartment without additional cooling
system
The temperature setting for the rear can be max. 3 °C higher than the temper-
ature in the passenger compartment. A lower temperature can not be set.
If the Climatronic detects that the passenger compartment has to be heated,
it activates the additional heat exchanger. The air outlets on the floor guide
warm air into the vehicle Ÿpage 156.
If the Climatronic detects that the passenger compartment has to be cooled,
cooled air is fed into the vehicle via the air outlets in the front of the vehicle
only Ÿpage 156.

it activates the additional heat exchanger. The air outlets on the floor guide

If the Climatronic detects that the passenger compartment has to be cooled,
cooled air is fed into the rear of the vehicle via the open air outlets in the roof

Air outlets for heating the passenger compartment
The air outlets Ÿfig. 121 for the passenger compartment heating system are
located at the bottom of the left side panel at the rear.

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.
39)Optional equipment40)Optional equipment
Heating, Ventilation and Air conditioning 158
•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.

Driving 166
•The reversing lights come on
•The heating or air conditioning automatically change to air recirculation
mode.
•The rear window heater switches on when the windscreen wiper is acti-
vated.
WARNING
•When the engine is running, the vehicle will start to move as soon as a
gear is engaged and the clutch released.
•Never select the reverse gear when the vehicle is in motion. Risk of acci-
dent.
Caution
•Do not rest your hand on the gear lever when driving. The pressure of your
hand could cause premature wear on the selector forks in the gearbox.
•When changing gear, you should always depress the clutch fully to avoid
unnecessary wear and damage.
•Do not hold the car “on the clutch” on hills. This causes premature wear
and damages the clutch. It can also prevent power being transferred from the
engine to the gearbox.
Automatic gearbox
Gearbox programs
The automatic gearbox has two gearbox programmes.
The gearbox management system is equipped with two driving programmes.
Depending on the driver or the driving situation, either a consumption
oriented programme or a more “sporty” programme will be selected.
The programme selection will be carried out automatically depending on how
the accelerator is used.
•The consumption-oriented programme will be selected if you use the
accelerator slowly or normally. This means that the gearbox will shift up
earlier and down later.
•A more “sporty” driving programme which shifts up gear later will be
selected if you use the accelerator more quickly.

Note
The two clutch system of the direct shift gearbox* has a system to protect
against excess strain, which may occur, for example, when the vehicle is held
on a hill with the clutch and the gearbox oil overheats. When the clutch is
overloaded, the vehicle begins to jerk and the position indicator of the
selector lever begins to flash. To avoid breakdowns, the clutch breaks the
power transmission between the engine and the gearbox, as a result of which
the vehicle loses impetus. If the clutch opens automatically due to over-
loading, depress the brake pedal and wait a few seconds before
continuing.
Selector lever positions
The selector lever positions and gears are shown on the
display in the combi-instrument.
Selector lever positions
The gear selected is displayed on the side of the selector lever and on the
display Ÿfig. 129 in the combi-instrument.
P - parking lock
When the selector lever is in this position, the drive wheels are locked
mechanically.
The parking lock must be engaged only when the vehicle is stationary Ÿ.
To move the selector lever from position P, the locking button in the selector
lever handle must be pressed and the brake pedal depressed at the same
time when the ignition is switched on.
Only the locking button has to be pressed to select the selector lever position
P.
If the battery has discharged, the selector lever cannot be removed from the
P position.
R - reverse gear
The reverse gear is engaged in this position.
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling Ÿ.
To move the selector lever to position R, press in the lock button and at the
same time press the brake pedal, with the ignition switched on.
With the selector lever in position R and the ignition switched on the
following occurs:
•The reversing lights come on
•The heating or air conditioning automatically change to air recirculation
mode.
•The rear window heater switches on when the windscreen wiper is acti-
vated.
