right or extreme left position:
•
Extreme right position - full heating,
•
Extreme left position - full cooling,
•
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
compartment.•
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on
at least once a month for approximately 5 mi
nutes 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.•

For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.
Operational problemsIf 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 on the air conditioning system
has blown. Check the fuse, replace it if
necessary
⇒page 258.
•
The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot
⇒page 18.
If you are not able to rectify the operat
ional problem yourself, or if the cooling
capacity decreases, switch the cooling sy
stem off. Contact a specialist garage.
Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains fully automatically a convenience temperature. 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 alte
r the settings manually. The
automatic mode

⇒ page 117 ensures maximum wellbeing of th
e 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
particularly at high outside temperatur
es 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 th
e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature. It is possible to briefly activate recirc
ulated air mode in order to enhance the
cooling effect
⇒page 118.
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 hi
gh 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! Recommended setting for all periods of the year:•

Move the air outlet vents
3 and
4, so that the air flow
is directed slightly
upwards. Aeration of the vehicle when ignition is switched off* On models fitted with power sliding/tilting roof with solar cells, the fresh air blower is automatically switched over
to “solar mode” if the sun ray's are sufficient after
switching off the ignition. The solar cells on
the sliding/tilting roof deliver power for
the fresh air blower. This supplies the interior of the car with fresh air. For an optimum ventilation, the air outlet vents
3 and
4 must be opened
⇒ page 108, fig. 137
.
The ventilation functions only when
the sliding/tilting roof is closed.

Setting temperatureYou can separate the interior temperature for the left and right side sepa-rately. – You can set the temperature for both sides after switching on the igni-
tion with the control dial .
– If you wish to set the temperature for the right side, turn the control
dial . The warning light in the bu
tton lights up, this indicates
that differing temperatures for the left and right side can be set.
If the warning light in the button lights up, the temperature for both sides cannot be set with the control dial . You
can reinitiate this function by pressing
the button . The warning light in the bu
tton which indicates the possibility to
set differing temperatures for the left and right side, goes out. You can set the interior temperature be
tween +18°C and +26°C. The interior
temperature is regulated automatically within this range. If you chose a tempera- ture lower than +18°C, a blue symbol lights
up at the start of the numerical scale. If
you chose a temperature higher than +26°C,
a red symbol lights up at the end of
the numerical scale. In both limit positi
ons the Climatronic operates at maximum
cooling or heating capacity, respectively.
The temperature is not controlled in this
case.

Auxiliary heating (auxiliary heating and ventilation)*Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or supplies the interior of the vehicl
e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating) The auxiliary heating (auxiliary heating) f
unctions in connection with the Climatic or
Climatronic. It can be used when stationa
ry, when engine is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The auxiliary heating (auxiliary heating)
warms up the coolant during the combus-
tion of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed is not set to zero) flows into the occupant compartment. Auxiliary ventilation The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching off the engine, whereby the interior temperature is effectively decreased (e.g. with the vehicle parked in the sun).
WARNING
•
The auxiliary heating must never be operated in closed rooms - risk of
poisoning!•
The auxiliary heating must not be running during refueling - risk of fire.
•
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the
vehicle, if you wish to operate the
auxiliary heating, in su
ch a way that the exhaust gases of the auxiliary
heating can come easily into contact
with inflammable materials (e.g. dry
grass) or easily inflammable su
bstances (e.g. fuel run out).
Note
•
If the auxiliary heating runs, the fuel
consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be operated, if there is very little fuel in the tank.•
The exhaust pipe of the auxiliary heating,
which is located on the underside of
the vehicle, must not be clogged and
the exhaust flow must not be blocked.
•
If the auxiliary heating and
ventilation is runni
ng, the vehicle battery discharges.
If the auxiliary heating and ventilation
has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the vehicle battery.•
The auxiliary heating only switches the bl
ower on, if it has achieved a coolant
temperature of approx. 50 °C.•
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.

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
the same time switched on low beam or
main beam or other electrical compon
ents with major po
wer 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 running and thus getting damaged. Ignition key withdrawal lock (automatic gearbox) You can only withdraw the ignition key after switching off the ignition if the selector lever is in position
P.
WARNING
•
When driving, the ignition key must always be in the position (igni-
tion 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 unex- pected locking of the steering wheel - risk of accident!•
Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (by applying the handbrake or moving the selector lever into the position P). The steering lock
can engage immediately - risk of acci-
dent!•
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 star
t the engine or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!

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 th
e 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 258.
•
Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the 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 turning the ignition key from posi-

WARNING
•
Never switch off the engine before the
vehicle is stationary - risk of acci-
dent!•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine 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 yo
ur journey
after the
engine has been operated for a lengthy peri
od 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 conti
nue running for a further 10
minutes or
so after the
engine and the ignition have
been switched off. The coolant fan may, however, also
switch on again after some time if the
coolant temperature rises because of an
accumulation of heat in the engine or
if the engine is warm and the engine
compartment is additionally
heated by strong sunlight.
•
This is why particular care is required when carrying out any work in the engine
compartment
⇒page 225, “Working in the engine compartment”.
Shifting (manual gearbox)Shift into reverse only when the vehicle is
stationary. Depress the clutch pedal and
hold it fully depressed. Wait a moment be
fore engaging reverse gear in order to
avoid any shift noises.

Rear parking aid*The parking aid provides a warning of obstacles behind the vehicle.The audible parking aid determines the distance between the rear bumper and an obstacle located behind the vehicle with
the aid of ultrasound sensors. The tones
of the parking aid can be adapted in
the menu of the information display*
⇒ page 29. The sensors are integrated in the rear bumper. Range of sensors The clearance warning begins at a distance
of about 160 cm from the obstacle (area
⇒fig. 149
). The interval between the warning signals becomes shorter as the
clearance is reduced. A continuous tone sounds from a distance
of approx. 30 cm (area ) - danger area.
You should not reverse any further after this signal sounds!
If the vehicle is
equipped with a factory-fitted towing device*, the border of the danger area starts, continuous tone, 5 cm further behind th
e vehicle. The vehicle can be extended
through an installed detachable towing device. On vehicles equipped with a factory-fitted
radio* or navigation*, the distance to the
obstruction is shown graphically on the disp
lay. On vehicles with a factory-fitted
towing device, the sensors are deactivated when towing a trailer. The driver is also informed of the radio* or the navigation
* by a graphic display (vehicle towing a
trailer) on the display. The radio* or navi
gation*, which is factory-fitted, can be set
so that the play function volume decrea
ses when activating the parking aid, see
Owner's Manual radio* or navigation*. This
improves the audibility of the parking
aid. Activating The parking aid is activated automatically when
reverse gear
is engaged and the
ignition is turned on. This is conf
irmed by a brief acknowledgement signal.
Deactivating The parking aid is deactivated by removing the reverse gear.
WARNING
•
The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehicle or carrying ou
t similar manoeuvres.
•
You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehicle. Such an obstacle might not
be within the range detected by the
sensors.•
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of th
e parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the parking aid.
Note
•
The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fi
tted towing device*).
•
If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no ob
stacle close to your vehicle, this indi-
cates a system fault. Have the fault rectified by a specialist workshop.•
The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
