Climatic (semi-automatic air conditioning system)*Description
Climatic is a combined cooling and heating system with electronic
control of the convenience temperature in the vehicle interior. It makes
it possible to optimally control the air temperature at any season of the
year.Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is operating
properly.
The air conditioning system operates when switch page 81, fig. 89 is
pressed and the following conditions are met:
engine running,

outside temperature above +2°C and

blower switch switched on (positions 1 to 4).
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly at high outside temperatures and a high air humidity. The system prevents the
windows misting up during th e cold season of the year.
The heating effect is dependent upon the c oolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculat ed air mode in order to enhance the cooling
effect  .
Air at a temperature of about 5°C may flow out of the vents under certain circum-
stances when the cooling system is operatin g. Lengthy and uneven distribution of the
air flow out of the vents (in particular at the leg area) and large differences in temper-
ature, for example when getting out of the ve hicle, can result in chills in sensitive
persons.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to
ensure that the heating and cooling systems operate properly. After switching on the cooling
Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
WARNING

For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and misting. Please familiarize yourself about
how to correctly operate the heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.

You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mo de off as soon as the windows begin
misting up.Note

We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the interior
of the vehicle forms deposits in the evapor ator of the air conditioning system. This
produces a permanent odour when the Climat ic is operating which can only be elimi-
nated through considerable effort and expense (replacement of compressor).

– When you again press the switch , the cooling system is switched off. The warning light in the button goes out.
The set temperature will be automatically maintained other than when the
control dial is on the extreme right or extreme left position:
Extreme right position - full heating.
Extreme left position - full cooling.
The controls and can be set to any desired intermediate position.
The blower should aways be on to prevent the windows from misting up.
Note

The whole heat output will be needed to unfrost the windscreen and side windows.
No warm air will be fed to the footwell. This can lead to restriction of the heating
comfort.

The used air streams out through the air removal openings in the luggage compart-
ment.

If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of de posits. Switch the air conditioning system
on at least once a month for approximately 5 minutes at the highest blower stage - also
during the cold season of the year - in order to remove such odours. Also open a
window for a short time.

Using the air conditioning system economicallyThe compressor on the Climatic uses powe r from the engine when in cooling mode
which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the interior
has been strongly heated through the effect of direct sunlight in order to allow the
heated air to escape.
The cooling system should not be switched on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the cooling
system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.Operational malfunctionsIf the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:
The fuse of the Climatic is defective. Check the fuse, replace it if necessary
 page 191.

The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot page 16.
If you are not able to rectify the operational problem yourself, or if the cooling capacity
decreases, switch the cooling system off. Contact a specialist garage.
Climatronic* (automatic air conditioning)Description
The Climatronic system is a combinat ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains a constant temperat ure fully automatically, once it has been
set. This is achieved by automatically varying the temperature of the outflowing air, the
blower stages and the air distribution. The system also takes into account sunlight
which eliminates the need to alter the settings manually. The automatic mode
 page 86 ensures maximum wellbeing of the occupants at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
engine running,

outside temperature above approx. +2°C,

switched on.
If the cooling system is switched on, th e temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly at high outside temperatures and a high air humidity. The system prevents the
windows misting up during the cold season of the year.
The heating effect is dependent upon the coolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculat ed air mode in order to enhance the cooling
effect  .
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to
ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a high coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!AC

The automatic mode is switched off by pressing the button for the air distribution or
increasing or decreasing the blower speed. The temperature is nevertheless
regulated.Defrosting windscreenDefrosting windscreen - switching on– Press the button page 85, fig. 90 .Defrosting windscreen - switching off– Once again press the button or the button . The temperature control is controlled automatically. More air flows out of the air outlet
vents
1 and 2.
Setting temperature– You can set the desired interior temperature after switching on the ignition with the
control dial .
You can set the interior temperature betw een +18°C (64°F) and +29°C (86 °F). The
interior temperature is regulated automatica lly within this range. If you select the
temperature below +18°C (64°F), “LO” appears in the display. If you select the temper-
ature higher than +29°C (86°F), “HI” appears in the display. In both limit positions the
Climatronic operates at ma ximum cooling or heating capacity, respectively. The
temperature is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg
area) and large differences in temperature, for example when getting out of the vehicle,
can result in chills in sensitive persons.Controlling blower
There are a total of seven blower stages available.The Climatronic system controls the blower st ages automatically in line with the inte-
rior temperature. You can also, however, adap t the blower stages manually to suit your
particular needs.
– Turn the control dial  page 85, fig. 90 to the left (reduce blower speed) or right
(increase blower speed).
If you switch off the blower, th e Climatronic is switched off.
WARNING

“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.

Do not switch the Climatronic system off for longer than necessary.

Switch the Climatronic system on as soon as the windows mist up.

Starting-off and DrivingSetting steering wheel positionFig. 91 Adjustable steering wheel: Lever be low the steering column / Safe distance to
steering wheelYou can set the height and the forward/back position of the steering wheel to the
desired position.
– Adjust the driver seat  page 57.
– Pull the lever below the steering column  fig. 91 down .
– Set the steering wheel to the desired position (concerning height and forward/back position).
– Then push the lever up against the steering column until it locks into place.
WARNING

You must not adjust the steering wheel when the vehicle is moving!

The driver must maintain a distance of at least 25 cm to the steering wheel
 fig. 91 on the right. Not maintaining this minimum distance will mean that
the airbag system will not be able to properly protect you - hazard!

For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its po sition unintentionally when driving - risk of acci-
dent!

If you adjust the steering wheel furthe r towards the head, you will reduce
the protection offered by the driver airbag in the event of an accident. Check
that the steering wheel is aligned to the chest.

When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the
steering wheel or at the inne r steering wheel edge). In such cases, injuries to the
arms, the hands and the head can occur when the driver airbag is deployed.

period otherwise the vehicle battery will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering wheel until the
steering locking pin is heard to engage. You should always lock the steering as a general
rule if you leave your vehicle. This acts as a deterrent against possible theft of your
vehicle .
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot
easily be turned into this position, in order to release the steering lock.
Position
The engine is started in this position. At th e same time switched on low beam or main
beam or other electrical components wi th major power consumption are briefly
switched off. The ignition key moves back into position when one releases the key.
The ignition key must be turned back into position each time before starting the
engine again. The starter repeat lock in th e ignition lock prevents the starter being
engaged when the engine is r unning and thus getting damaged.
WARNING

When driving, the ignition key must always be in the position (ignition
switched on) without the engine running. This position is indicated by the
warning lights coming on. If this is not the case, it could result in unexpected
locking of the steering wh eel - risk of accident!

Do not withdraw the ignition key from the lock until the vehicle has come to
a stop. The steering lock can engage immediately - risk of accident!

Always withdraw the ignition key if you are going to leave the vehicle, even
for a short time. This is particularly important if children are left in the vehicle.
The children might otherwise start the en gine or operate electrical equipment
(e.g. power windows) - risk of injury!
Starting the engineGeneral
You can only start the engine only using an original ignition key.
Place the gearshift lever into neutral and put on the handbrake firmly before
starting the engine.

The clutch pedal should be fully depressed when starting the engine - the starter
then only has to crank the engine.

Let go of the key as soon as the engine starts otherwise there may be damage to
the starter.
The engine running noises may louder at first be louder for a short time after starting
the cold engine until oil pressure can be built up in the hydraulic valve clearance
compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid page 186.
It is only possible to tow-start vehicles fi tted with a manual gearbox. The tow-starting
distance must not be more than 50 metres page 189.
WARNING

Never run the engine in non ventilated or enclosed areas. The exhaust gases
of the engine contain besides the odorless and colourless carbon monoxide a
poisonous gas - hazard! Carbon mono xide can cause unconsciousness and
death.

Never leave your vehicle unattended with the engine running.Caution

The starter may only be operated (ignitio n key position ), if the engine is not
running. If the starter is imme diately operated after switchin g off the engine, the starter
or the engine can be damaged.

Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!


Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away. When
driving the engine reaches its operating te mperature more rapidly and the pollutant
emissions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture
for every external air temperature.
Do not operate accelerator before and when starting engine.

Interrupt the attempt at starting after 10 seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.

It is possible that the fuse on the electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary page 191.

If the engine does not start, contact the nearest specialist garage to obtain profes-
sional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator after
the engine has started.
Diesel enginesGlow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside tempera-
ture.
The preglow indicator light
 comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.

You should start the engine immediately after the glow plug warning light
 has
gone out.

The glow plug warning light will come on for about one second if the engine is at a
normal operating temperature or if the outside temperature is above +5°C. This means
that you can start the engine right away.

Interrupt the attempt at starting after 10 seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.

It is possible that the fuse on the diesel preglow system is defect if the engine still
does not start. Check the fuse and replace it if necessary page 191.

Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of all
be filled while the attempting to start the engine.
Switching off the engine– The engine can be switched off by turnin g the ignition key from position into
 page 87, fig. 92 .
WARNING

Never switch off the engine before the vehicle is stationary - risk of accident!

The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy period at high loads but should be allowed it
to run at idling speed for about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.
Note

The radiator fan may continue running fo r a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
