Setting temperature
– Press the button or ⇒page 114, fig. 110 and continue
pressing until the desired temperature is set.
You can set the interior temperature between +18 °C (64 °F) and +29 °C
(86 °F). The interior temperature is regulated automatically within this
range. If you select the temperature below 18 °C (64 °F), “LO” appears in
the display. If you select the temperature higher than 29 °C (86 °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 partic-
ular at the leg area) and large differences in temperature, 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 blower stages automatically
in line with the interior temperature. You can also, however, adapt
the blower stages manually to suit your particular needs.
Setting blower stages
– Press the button or the button to set the blower stage.
The number of dashes in the display ⇒page 114, fig. 110 indicates
the blower stage.
If OFF is shown in the display, this indicates that the Climatronic system
is switched off ⇒ page 118.
WARNING
•“Stale air” may result in fatigue in the driver and occupants,
reduce attention 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 neces-
sary.
•Switch the Climatronic system on as soon as the windows mist
up.

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To lock the steering , with the ignition key withdrawn, turn the steering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 components 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 the 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.

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 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 electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 260.
•If the engine does not start, 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 temperature. 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 260.
•If the engine does not start, contact the nearest specialist garage to
obtain professional assistance.
Starting the engine after 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 the engine off
– Turn the ignition key into position ⇒page 121, fig. 115 .A1

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 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 changing gears, in order to avoid
unnecessary wear and damage.
Handbrake
Applying 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. 118 .
– Hold the button pressed and push the handbrake lever down fully ⇒ .
The handbrake warning light 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 5
km/h for more than 3 seconds.
WARNING
•Please note that the handbrake must be fully released. A hand-
brake which is only partially released can result in the rear brakes
overheating which will have a nega tive 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!

car, 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.
The audible parking aid determines the distance between the front or rear
bumper and an obstacle with the aid of ultrasound sensors. The sensors
are integrated in the front and rear bumper. The signal tones for the front
parking aid sound lower than for the rear parking aid.
Range of sensors
The distance warning begins at a distance of about 60 cm from the
obstacle in front of the vehicle (area ⇒fig. 121 ) and about 160 cm
from the obstacle behind the vehicle (area ⇒page 126, fig. 119 ). The
interval between the warning signals becomes shorter as the clearance is
reduced.
A continuous tone sounds from a clearance of just 30 cm (Bereich ) -
danger area. From this moment on do not continue driving in the
selected direction or the direct ion from where the obstacle is
reported!
Activating
The parking aid is activated when the reverse gear is engaged and the
ignition is turned on or by pressing the button ⇒fig. 120 - the symbol

Storing a speed
– Move the slide switch ⇒fig. 122 into the ON position.
– After the desired speed has been reached, press the rocker button into the SET position.
After you have pressed press button into the SET position, the speed
you have just selected is maintained at a constant speed without having
to depress the accelerator.
You can increase the speed by depressing the accelerator. Releasing the
accelerator will cause the speed to drop again to the set speed.
This does not apply, however, if you drive at a speed which is more than
10 km/h higher than the set speed for a period of more than 5 minutes.
The stored speed will be cancelled in the memory. You then have to re-
store the desired speed.
One can reduce the speed in the usual manner. The system is switched
off temporarily by actuating the brake or clutch pedal ⇒page 130.
WARNING
First ensure that it is not too high for the traffic conditions which
exist at that moment before resuming the stored speed.
Changing a stored speed
You can also change the speed of the vehicle without
depressing the accelerator.
Faster
– You can increase the stored speed without depressing the
accelerator, by pressing the rocker button ⇒fig. 122 into
the RES position.
– The speed of the car will increase continuously if you hold the rocker button pressed in the RES position. Once the car has
reached the desired speed, release the rocker button. The set
speed is then stored in the memory.
Slower
– You can reduce the stored speed by pressing the rocker
button in the SET position.
– Holding down the rocker button pressed in the SET position
will cause the speed of the vehicle to reduce continuously.
Once the car has reached the desired speed, release the
rocker button. The set speed is then stored in the memory.Fig. 122 Operating

Information for driving wi th an automatic gearbox
Shifting up and down through the gears is performed auto-
matically.
You can also, however, switch the gearbox over into the
Tiptronic mode . This mode makes it possible for you to also shift
gears manually ⇒ page 135.
Starting-off and Driving
– Depress the brake pedal and hold it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the selector lever into the desired position, e.g. D
⇒ page 132, and then release the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engage- ment nudge can be felt).
– Release the brake pedal and depress the accelerator ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected
when stopping just for a short time, such as at a cross roads.
It is sufficient to hold the vehicle stationary using the foot
brake. The engine can, however, be allowed just to idle. Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the
selector lever to P and then release the Shiftlock button.The engine can only be started when the selector lever is in position P or
N ⇒ page 122.
It is sufficient to engage selector lever position P when parking on a flat
surface. When parking on a slope you should first apply the handbrake
firmly and then move the selector lever into position P. This is to ensure
that there is no excessive pressure acting on the lock mechanism and that
it is easier to subsequently move the selector lever out of position P.
If the selector lever position N is selected by accident while driving it is first
necessary to release pressure on the accelerator pedal and wait for idling
speed of the engine to be reached before engaging a drive position in the
selector lever.
WARNING
•Do not depress the accelerator when changing the position of
the selector lever if the car is stationary and the engine is running
- risk of accident!
•Never move the selector lever into position R or P when driving
- risk of an accident!
•When the engine is running and the vehicle is stationary, it is
necessary to hold the car with the brake pedal in all the positions
of the selector lever (except P and N) since the power transmission
