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 distribution
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 t unnel or when standing in a traffic jam. If
a considerable increase in concentration of pollutants is recognized by the air 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 distribution 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 switch on the air distribution control automatically
when there is a nauseating 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 atten- tion 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
If the windscreen mists up, press the button page 114, fig. 122 . 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 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.
– 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.

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.
Before starting the engine, on vehicles fitted with automatic gearbox with the
KESSY system*, it is necessary to depress th e brake pedal and to hold it pressed until
the engine starts. If you start the engine without depressing the brake pedal, the engine
does not start and a message is shown in the display of the instrument cluster to
remind you of the necessity to depress the brake 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 241.
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.

Starting-off and Driving
124WARNING
Never switch off the engine before the ve hicle 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
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 216, “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 to the clutch and gearbox parts.
HandbrakeApplying the handbrake– Pull the handbrake lever up fully.Releasing the handbrake– Pull the handbrake lever up slightly and at the same time press in the locking
button fig. 128 .

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).KESSY system*IntroductionThe KESSY system makes it possible to switch the ignition on/off and to start/stop the
engine without actively using the key.

Note
The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device*).
If a warning signal sounds for about 3 seconds after switching the ignition on and
engaging reverse gear, and there is no obstac le close to your vehicle, this indicates 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.
Front and rear parking aid*
The parking aid provides a warning of obstacles in front and behind the
vehicle.Fig. 132 Activating the parkin g aid / parking aid: Detection range of the front sensorsThe audible parking aid determines the distance between the front or rear bumper and
an obstacle with the aid of ultrasound sens ors. The sensors are integrated in the front
and rear bumper. The signal tones for the fr ont parking aid sound higher as standard
than for the rear parking aid. The tones of the parking aid can be adapted in the menu
of the information display* page 25.
Range of sensors
The distance warning begins at a distance of about 120 cm from the obstacle in front
of the vehicle (area fig. 132 ) and about 160 cm from the obstacle behind the
vehicle (area fig. 132). 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.
From this moment on do not continue driving! If the vehicle is equipped with a
factory-fitted towing device*, the border of the danger area starts - continuous tone -
5 cm further behind the vehicle. The vehi cle can be extended through an installed
detachable 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 rear sensors are deactivated when towing a trailer. The driver is
informed about this by a graphic display (vehic le towing a trailer) in the radio* or the
navigation* display. The factory-fitted radio* or navigation system* can be set so that
the play function volume decreases when activating the parking aid, see Owner's
Manual radio* or navigation system*. This improves the audibility of the parking aid.
Activating
The parking aid is activated when the reverse gear is engaged and the ignition is
turned on or by pressing the button fig. 132 - the symbol
lights up in the button.
The activation is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated after pressing the button°
fig. 132 or at a speed of
more than 10 km/h - the symbol
in the button is no longer illuminated.
WARNING
The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's re sponsibility to take care when reversing the vehicle or
carrying out similar manoeuvres.
You should therefore satisfy yourself, before reversing, that there is no small
obstacle, such as a rock, thin post, trailer drawbar etc., in front or 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 the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the parking
aid.

same time on the driver and front passenger side.
If the sensors find a suitable parking space, they store its parameters until another
suitable parking space has been found or until a distance of 10 m had been driven after
finding the parking space. This is why it is possible to switch on the park assist after
driving past the parking space, the information on whether this parking space is suit-
