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.
Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.
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.
Switching recirculated air mode on
– Press the button - the warning light lights up in the button.
Switching recirculated air mode off
– Press again the button or the button - the warning light in
the button goes 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 109, fig. 125 . After the
windscreen has been demisted, press the button .
Setting temperature
You 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 .
If the temperature for the right side was set via the control dial , it can no longer
be set via the control dial - temperature fo r both sides. This is only possible if
you press the button for about 2 seconds.
You can set the interior temperature between +16 °C (60 °F) and +29,5 °C (85 °F).
The interior temperature is regulated automatically within this range. If you select
the temperature below +16 °C (60 °F), “LO” appears in the display. If you select the
temperature higher than +29,5 °C (85 °F), “HI” appears in the display. In both limit
positions 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 temperat ure, 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 bl ower stages automatically in line
with the interior temperature. You can also, however, adapt the blower
stages manually to suit your particular needs.
– Turn the control dial ⇒page 109, fig. 125 to the left (reduce
blower speed) or right (increase blower speed).
Switch off the blowers, the Climatronic is switched off and in the display shows OFF.

Programming
For the programming of the auxiliary heatin g (auxiliary heating and ventilation) in
the menu Aux. Heating there are three pre-set times:
•Pre-set time 1
•Pre-set time 2
•Pre-set time 3
In each pre-set time, the day (if necessary each day = daily) and the time (hour and
minute) can be set for the operating period of the auxiliary heating and/or ventila-
tion.
If you leave the pre-se t menu by selecting menu Back or do not operate the display
for longer than 10 seconds, the set values are stored, but the pre-set time is not
active.
Both other pre-set times can be prog rammed and stored in the same way.
If you select the menu Activate after setting the desired values, Pre-set time
(weekday, hours, minute) activated! is displayed in the display and the set pre-
set time is active.
Only one programmed pre-set time can be active.
The last programmed pre-set time remains active.
The active pre-set time can be changed in the menu Aux. Heating in the menu
Activation by selecting a pre-set time.
The prerequisite for the correct switching on of the auxiliary heating (auxiliary
heating and ventilation) according to the programmed pre-set time is the correct
setting of the current time ⇒page 14 and weekday ⇒page 113.
If the system is running, a warning light in the button for direct switching on/off of
the auxiliary heating lights up. The running system deactivates after expiration of the operating period or is deac-
tivated earlier by pressing the button for
direct switching on/off of the auxiliary
heating ⇒page 114.
The deactivation of a desired pre-set time can be performed by selecting the menu
Deactive in the menu Active .

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 such 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 heat ing and ventilation is running, 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 sw itches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
•At low outside temperatures, this can resu lt in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
•After switching off the auxiliary heating, the coolant pump runs for a short
period.
•The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicate s a low loading state.
•The auxiliary heating (auxiliary heating) switches on, if in the information
display: Please refuel! is indicated or was indicated before switching off the igni-
tion.
•When driving, the auxiliary heating can only be switched on, if the exterior
temperature is lower than 5 °C.
•The air inlet in front of the windscreen mu st be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
•So that the warm air can flow into the vehicle interior after switching on the
auxiliary heating (auxiliary heating), the control dial ⇒page 100, fig. 119 must
be turned up to the stop to the right when heating. With Climatic and Climatronic,
you can maintain the temperature norma lly selected by you (we recommend 22
°C). It is recommended to put the air flow in the position
. For heating and
climatic put the blower switch ⇒page 100, fig. 119 if necessary ⇒page 104,
fig. 122 in the position 2.
•On vehicles with DPF (die sel particle filter) the warm coolant heats up the
engine.

Setting steering wheel position
You can set the height and the forward/back position of the steering
wheel to the desired position.
– Adjust the driver seat ⇒page 67.
– Pull the lever below the steering column ⇒fig. 130 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 wh eel when the vehicle is moving!
•The driver must maintain a distance of at least 25 cm to the steering
wheel ⇒fig. 131 . Not maintaining this minimum distance will mean that the
airbag system will not be able to properly protect you - hazard!
•For s afe ty re a so ns t he le ve r m ust al wa y s b e fi rm ly pus he d up to a voi d the
steering wheel alteri ng its position unintentionally when driving - risk of
accident!
•If you adjust the steering wheel furthe r towards the head, you will reduce
the protection offered by the driver airb ag 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 inner steering wheel edge). In such cases,
injuries to the arms, the hands and the head can occur when the driver
airbag is deployed.

Ignition lock
Petrol engines
- ignition switched off, engine off, the steering can be locked.
- ignition switched on
- start engine
Diesel engines - interruption of fuel supply, ignition switched off, engine off, the steering can
be locked.
- heating glow plugs on, ignition switched on
•You should not switch on any major elec trical components during the heating
period otherwise the vehicle batter y 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 the same time switched on low beam or
main beam or other electrical compon ents with 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 ru nning 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 (put on the handbrake or select the selector lever posi-
tion P). The steering lock can enga ge 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 star t the engine or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!

Starting the engine
General
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 238.
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 242.
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 immediately 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 exhaust 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 vehicle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines
These 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 243.
•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 engines
Glow 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
comes on after the igniti on has been switched on.
