increases. Switch recirculated air mode off as soon as the windows begin
misting up.
Note
If the windscreen mists up, press the button page 102, fig. 108 . After
the windscreen has been demisted, press the button .
The automatic air distribution control oper ates 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 blower stages automatically in line with the inte-
rior temperature. You can also , however, a dapt the bl ower stages ma nua lly to suit y our
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.
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.

vents 1.Auxiliary heating (auxiliary heating and ventilation)*Description and important information
The auxiliary heating (auxiliary he ating 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) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne 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) wa rms up the coolant during the combustion
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 runn ing 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 vehicl e, 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 mate rials (e.g. dry grass) or easily inflam-
mable substances (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 op erated, 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 running, the vehicle battery discharges. If
the auxiliary heating and ventilation has be en operated several times over a longer
period, the vehicle must be driven a few ki lometers in order to recharge the vehicle
battery.
The auxiliary heating only switches the blower 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.
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 indicates a low loading state.
The auxiliary heating (auxiliary heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please refuel!
(Please refuel!) .
The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the auxiliary heating operates properly.
So that warm air can flow into the vehicl e interior after switching on the auxiliary
heating, you must maintain the temperature normally selected by you (we recom-
mend 22°C). It is recommended to put the air flow in the position
.
On vehicles with DPF (diesel particle filter) the warm coolant heats up the engine.
Direct switching on/offThe auxiliary heating (auxiliary heating and vent ilation) can be switched on or off at any
time directly using the button on the operating part of the Climatic fig. 109 or
on the operating part of the Climatronic.
If the auxiliary heating and ventilation is not switched off earlier, it switches off auto-
matically after the expiration of the set operating period, in the menu Running time.Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.Basic setting– On the information display, select from the Main menu the menu point
Aux. heating .
– In the menu Aux. heating select the menu point Weekday and set the current day.
– Return to a higher level by selecting the menu point Back, i. e. in the menu

– In the menu Aux. Heating select the menu point Running time and set the
desired operating period in steps of 5 m inutes. The running time can be 10 to 60
minutes.
– By selecting the menu point Back, you will reach in the menu Aux. Heating.
– In the menu Aux. heating select the menu point Mode.
– In the menu Mode select the desired mode Heating for or Ventilation for .ProgrammingFor the programming of the auxiliary heating (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 and the time (hour and minute) can be set for switching
on the auxiliary heating and/or ventilation.
An empty position can be fo und between Sunday and Monday when selecting the day.
If this empty position is selected, the activation is performed without taking into
account the day.
If you leave the pre-set menu by selecting the menu Back or do not make changes on
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 programmed and stored in the same way.
If you select the menu Activate after setting the desired values, appears on the display
Pre-set time (weekday, hours, minute) activated! 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.
After the auxiliary heating activates at the set time, it is necessary to pre-set a time
again.
Changing the active pre-set time is carried out after selecting the menu point Activate
in the menu Aux. heating 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 and the weekday page 105.
If the system is running, a warning light in th e button for direct switching on/off of the
auxiliary heating lights up.
The running system deactivates after expirati on of the operating period or is deacti-
vated earlier by pressing the button for direct switching on/off of the auxiliary heating
page 105.
A random pre-set time can be deactivated by selecting the menu point Deactivate in
the menu Activate.
After selecting the menu point Fa ct or y se t ti ng in the menu Aux. heating , it is possible
to return to the factory setting.

– Pull the lever below the steering wheel down fig. 110 - left .
– Set the steering wheel to the desired position (concerning height and forward/back position).
– Push the lever upwards as far as the stop.
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. 110 - 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 po sition. 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.

You should not switch on any major elec trical components during the heating
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.
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 (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!
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 imme diately - 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 start the engi ne 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.
Before starting, it is necessary to depres s the clutch pedal and to hold it pressed
until the engine starts. If you start the engi ne without depressing the clutch pedal, the
engine does not start and a message is shown in the display of the instrument cluster
to remind you of th e necessity to depress the clutch pedal.
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 221.
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 225.

poisonous gas - hazard! Carbon monoxide 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 immedi ately 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 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. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis-
sions 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 226.
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 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 226.
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 turnin g the ignition key from position into
page 107, fig. 111.

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
switch on again after some time if the co olant temperature rises because of an accu-
mulation 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 197, “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 mo ment before engaging reverse gear in order to avoid any
shift noises.
The reversing lights will come on once reverse gear is engaged, provided the ignition 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 pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over
a period of time, lead to earl y wear of the gearshift forks.
Depress the clutch pedal fully when changi ng gears, in order to avoid unnecessary
wear and damage.

A warning signal sounds and the following text appears in the display* if you have inad-
vertently driven off with the handbrake applied:
Release parking brake!
The handbrake warning is acti vated 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 result 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 P (automatic gearbox).
Rear parking aid*The parking aid provides a warning of obstacles behind the vehicle.The audible parking aid determines the di stance between the rear bumper and an
obstacle located behind the ve hicle with the aid of ultrasound sensors. The tones of
the parking aid can be adapted in th e menu of the information display* page 25.
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. 114 ). The interval between the warning signals becomes shorter as the clear-
ance 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 deta chable towing device.
On vehicles equipped with a factory-fitted radio* or navigation system*, the distance
to the obstruction is shown graphically in the display. On vehicles with a factory-fitted
towing device, the sensors are deactivated when towing a trailer. The driver is informed
about this by a graphic display (vehicle towing a trailer) in the radio* or the navigation*
display. The factory-fitted radio* or navigati on system* can be set so that the play func-
tion volume decreases when activating the parking aid, see Owner's Manual radio* or
navigation system*. This improves the audibility of the parking aid.
