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:•
Set the desired temperature, we recommend 22 °C.

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.

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.

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.Recirculated air mode In recirculated air mode air is sucked
out of the interior of the vehicle
and then fed back into the interior. When the automatic air distribu-tion control is switched on, an air quality sensor measures the concentration of pollutants in the drawn-in air.Recirculated air mode prevents polluted air outside the vehicle from getting into the vehicle, for example when driving through a tunnel or when standing in a traffic jam. If a considerable increase in concentration of pollutants is recognized by the ai
r quality sensor, when the automatic
air distribution control is switched
on, the air distribution control will
temporarily be switched off. If the concentration of pollutants decreases to the normal level, the air distributi
on control is automatically switched
off so that fresh air can be guided into the vehicle interior. Switching recirculated air mode on – Press the button repeatedly until the warning light on the left
side of the button lights up.
Switch on automatic air distribution control – Press the button repeatedly until the warning light on the right
side of the button lights up.
Switch off automatic air distribution control temporarily – If the air quality sensor does not sw
itch on the air distribution control
automatically when there is a nausea
ting smell, you can switch it on
yourself by pressing the button *.
The warning light lights up in
the button on the left side.
Switching recirculated air mode off – Press the button or press the button repetitively, until the
warning lights in the button go out.
WARNING
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 acci- dent increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
If the windscreen mists up, press the button
⇒page 116, fig. 141
.
After the windscreen has been demisted, press the button .•
The automatic air distribution control operates only if the outside temperature
is higher than approx. 2°C.Controlling blower There are a total of seven blower stages available.The Climatronic system controls the bl
ower stages automatically in line
with the interior temperature. You
can also, however, adapt the blower
stages manually to suit your particular needs. – Press again the button on the left side (reduce blower speed) or on
the right side (increase blower speed).
If you switch off the blower, th
e Climatronic is switched off.
The set blower speed is displayed above the button when the respective number of warning lights come on.

- 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
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!

Starting the engineGeneral You can only start the engine only using an original ignition key.•
Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox)
and put on the handbrake firmly before
starting the engine.•
The clutch pedal should be fully depressed when starting the engine which
means that the starter 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 ma
y 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 no
rmal 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 252.
It is only possible to tow-start vehicles
fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres
⇒page 256.
WARNING
•
Never run the engine in non ventilat
ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon monoxide a poisonous gas - hazard!
Carbon monoxide can cause uncon-
sciousness and death.•
Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is i
mmediately operated
after switching 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 exhaus
t gas catalytic conver
ter 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 vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature 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 befo
re 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 electrical fuel pump 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.
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 temper-ature. The preglow indicator light

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.

The reversing lights will come on once reverse gear is engaged, provided the igni- tion is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•
One should not lay the hand on the shift lever while driving the vehicle. The
pressure of the hand will be transferred to
the gearshift forks in the gearbox. This
can, over a period of time, lead to early wear of the gearshift forks.•
Depress the clutch pedal fully when chan
ging gears, in order to avoid unneces-
sary wear and damage to the clutch.HandbrakeApplying the handbrake – Pull the handbrake lever up fully.

 lights up when the handbrake is applied, provided
the ignition is on. A warning signal sounds and the following text appears in the display* if you have inadvertently driven off with the handbrake applied:
Handbrake on
The handbrake warning is activated if you drive at a speed of more than 6 km/h for more than 3 seconds.
WARNING
•
Please note that the handbrake must be fully released. A handbrake
which is only partially released can re
sult in the rear brakes overheating
which will have a negative effect on the operation of the brake system - risk of accident! In addition this can result in premature wear of the rear brake pads.•
Never leave children unattended in the vehicle. The children might, for
example, release the handbrake or take the vehicle out of gear. The vehicle might then move off - risk of accident!
Caution
After the car has come to a stop, always firs
t of all apply the handbrake firmly before
then additionally engaging a gear (manual gearbox) or moving the selector lever into position
