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. 119. Not maintaining this minimum distance will mean that the
airbag system will not be able to properly protect you - hazard!
•
For s a fe t y re a s ons the le v e r m ust a lwa y s b e fi rm l y pus he d up t o a vo id the
steering wheel altering its position unintentionally when driving - risk of
accident!
•

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 another vehicle as a jump-start aid ⇒page 213.
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 216.
WARNING
•
Never run the engine in non ventilated 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 operating 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. When
driving 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 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 218.
•
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 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
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 218.

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 first of all apply the handbrake firmly before
then additionally engaging a gear (manual gearbox) or moving the selector lever
into position P (automatic gearbox).Parking aid*The parking aid provides a warning of obstacles behind the vehicle.The audible parking aid determines the distance between the rear bumper and an

Storing a speedThe cruise control system is operated by means of the switch and
rocker button in the left lever of the multi-functional switch.
– Press the switch ⇒fig. 124 into the position ON.
– After the desired speed has been reached, press the rocker button
into the SET- position - the current speed is stored.After you have released the rocker button out of the position SET-, the speed
you have just stored is maintained at a constant speed without having to depress
the accelerator.
Yo u c a n increase the speed by depressing the accelerator. Releasing the acceler-
ator 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 longer 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 tempo-
rarily by actuating the brake or clutch pedal ⇒page 106.
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.Fa s t er
–You can increase the stored speed without depressing the acceler-
ator, by pressing the rocker button ⇒fig. 124 into the RES+ posi-
tion.
– The speed of the car will increase continuously if you hold the rocker
button pressed in the RES+ position. Once the vehicle has reached
the desired speed, release the rocker button. The set speed is then
stored in the memory.
Slower
–You can decrease the stored speed by pressing the rocker button
in the SET- position.
– Holding down the pushbutton pressed in the SET- position will cause
the speed of the vehicle to reduce continuously. Once the vehicle has
reached the desired speed, release the rocker button. The set speed is
then stored in the memory.
– If you release the rocker button when the vehicle is travelling at a
speed of less than 30 km/h, the speed is not stored, the memory is
erased. It is then necessary to again store the speed with the rocker
button in the position SET- after an increase in speed of the vehicle
to more than 30 km/hour.

Automatic gearbox6-speed automatic gearbox*IntroductionYour car is equipped with an electronically controlled 6-speed automatic gearbox.
Shifting up and also down through the gears is performed automatically.
At the same time this is a conventional automatic gearbox. The maximum speed is
reached in the 5th gear. The 6th gear serves as an economic driving programme,
which is intended to reduce the fuel consumption.Information for driving with an automatic gearbox
Shifting up and down through the gears is performed automatically.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 110.
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 108,
and then release the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engagement
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 stop-
ping 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 100.
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 neces-
sary 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 acci-
dent!
•
Never move the selector lever into position R or P when driving - risk of
an accident!

Technical Data In certain circumstances (e.g. when driving in mountainous regions or when towing
a trailer) it may be beneficial to select the manual shift programme ⇒page 110 for
a short time in order to adapt the gearbox ratios manually to the driving situations.
S - Position for sporty style of driving
Shifting up later into a higher gear makes it possible to fully exploit the power
potential of the engine. The gearbox also then shifts down at higher engine speeds
as in the position D.
The gearbox does not shift into the 6th gear in the position S, because the
maximum speed is achieved with the 5th gear.
The Shiftlock on the selector lever grip must be pressed when moving the selector
lever out of the position D into the position S.
WARNING
•
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 is never completely inter-
rupted, also not when the engine is idling - the vehicle creeps.
•
You must on no account unintentionally operate the throttle (e.g. by
hand from the engine compartment) if a drive position is engaged when the
car is stationary. The vehicle would otherwise immediately start off - also
when the handbrake is firmly applied - risk of an accident!
•
You must move the selector lever into position P and firmly apply the
handbrake first before you or any other person opens the bonnet and starts
working on the engine when it is running - risk of accident! It is also essential
to observe all warnings ⇒page 185, “Working in the engine
compartment”.
Selector lever lockAutomatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and N.
You must first of all depress the brake pedal in order to move the selector lever out
of this position. The warning light
⇒page 35 lights up in the instrument cluster
as a reminder for the driver when the selector lever is in position P and N.
A time delay element ensures that the selector lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to seesaw out a stuck vehicle. The selector lever lock will click into place if the lever
is in the N position for more than 2 seconds without the brake pedal being pressed.
The selector lever lock is only active if the vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N when
the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock
5)- Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P. If the ignition key is withdrawn, the selector lever is blocked in
position P.
Note
On vehicles which are fitted with an automatic gearbox, you can withdraw the igni-
tion key after switching off the ignition in any position of the selector lever.5)This function is only valid for some countries.

– Push the selector lever to the right out of position D. After switching
over, 6 5 4 3 2 1 appears in the display with the currently engaged gear
being highlighted.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position)
⇒page 110, fig. 127 .
Shifting down gears
– One-touch back of the selector lever (in the Tiptronic position) .It is possible to switch over to manual both when the car is stationary and also when
driving.
When you accelerate, the gearbox shifts up automatically in gears 1, 2, 3, 4 and 5
into the next higher gear just before the maximum permissible engine speed is
reached.
If you select a lower gear, the automatic gearbox does not shift down until there is
no risk of the engine overrevving.
If you operate the kickdown function, the gearbox shifts into a lower gear in line
with the vehicle speed and engine speed.
Emergency programme
An emergency programme exists in the event of a fault in the system.The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
It is possible to continue to move the selector lever into all the positions. In the
positions D and S the gearbox remains engaged in the 3rd gear. It is also possible to
continue to engage reverse gear in the position R.
The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.Tow-starting and towing vehicle Tow-starting a vehicle
