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 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 215.
It is only possible to tow-start vehicl es fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres ⇒page 217.
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 oper ated 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 it s normal operating temperature - risk of damaging the
engine!
•Vehicles which are fitted wi th 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 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 electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary ⇒page 220.
•If the engine does not start, contact th e 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 ignition has been switched on.

Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal and hold
it fully depressed. Wait a moment before engaging reverse gear in order to avoid
any shift noises.
The reversing lights will come on once reve rse gear is engaged, provided the igni-
tion 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 or der to avoid unneces-
sary 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. 117.
– Hold the button pressed and push the handbrake lever down fully ⇒ .
The handbrake warning light lights up when the handbr ake is applied, provided
the ignition is on.

WARNING
•The parking aid is not a substitute fo r the driver paying proper attention
and it is always the driver's responsibility to take care when parking 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 po st, trailer drawbar etc., behind your
vehicle. Such an obstacle might not be within the range detected by the
sensors.
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 se conds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your 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 dist ance 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. 120 ) and about 160 cm from the obstacle behind the
vehicle (area ⇒page 104, fig. 118 ). The interval between the warning signals
becomes shorter as the clearance is reduced.
A continuous tone sounds from a cleara nce of just 30 cm (Bereich ) - danger
area. From this moment on do not continue driving in the selected direction or
the direction 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. 119 - 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. 119 or at a speed
of more than 15 km/h - the symbol in the button is no longer illuminated.

– After the desired speed has been reached, press the rocker button
into the SET position.
After you have pressed press rocker button into the SET position, the speed you
have just selected is maintained at a constant speed without having to depress the
accelerator.
Yo u c a n increase the speed by depressi ng 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 mo re 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 107.
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 e r
–You can increase the stored speed without depressing the acceler-
ator, by pressing the rocker button ⇒page 106, fig. 121 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
decrease 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.
– If you release the rocker button when the car 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 sp eed with the rocker button in
the position SET
after an increase in speed of the vehicle to more
than 30 km/h.
Switching off the cruise control system temporarily
–You can switch off the cruise control system temporarily by
depressing the brake pedal or clutch pedal, on models with auto-
matic gearbox and only with brake pedal.
– You can likewise switch off the cruise control system by pushing the switch ⇒page 106, fig. 121 to the right into the intermediate posi-
tion before the position OFF. The slide switch then moves back auto-
matically into the ON position.
The set speed remains stored in the memory.
The Resumption of the stored speed is achieved by releasing the brake or clutch
pedal, on vehicles fitted with automatic gearbox only after releasing the brake pedal
and after shortly pressing the rocker button ⇒page 106, fig. 121 into the posi-
tion RES.

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 113.
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 110,
and then release the Shiftlock button.
– Wait a moment until the gearbox ha s 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-
p i n g j u s t fo r a s h o r t t im e, s u c h a s a t 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 101.
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 accelerato r 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 an d the engine is running - risk of acci-
dent!
•Never move the selector lever into position R or P when driving - risk of
an accident!
•When the engine is running and the ve hicle 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".

The Shiftlock on the selector lever grip must be pressed when moving out of posi-
tion
4 into position D.
3 - Position when driving in mountainous regions
This position of the selector lever is suitable for long sloping sections.
The gearbox shifts up and down automatically into first, second and third gear in
line with engine load and vehicle speed. The fourth and fifth gears remain locked
out in order to avoid unnecess ary gear changes. Enhanced engine braking power is
thus available.
The Shiftlock on the selector lever grip must not be pressed when moving out of
position 3 into position 4.
2 - Position for extreme mountainous sections
This position of selector lever is suit able for very steep downhill sections.

engine load and vehicle speed. Third, fourth and fifth gears are not engaged. This
position offers you the maximum possible engine braking power.
The Shiftlock on the selector lever grip must be pressed when moving out of posi-
tion 2 into position 3.
The cruise control system is locked in position 2.
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 ot herwise 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 othe r 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”.
Note
•Take your foot off the accelerator if you inadvertently shift into N when driving
and wait until the engine speed has dropped to the idling speed range before
shifting into D.
•If you shift gear manually it is possible to select positions 4, 3 and 2, but the
automatic gearbox will not shift down until there is no risk of the engine
overrevving.
Selector lever lock
Automatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and N .
You must depress the brake pedal first and press the Shiftlock button at the same
time in order to move the selector lever out of these positions. The following will be
displayed in the information display*:
"Apply foot brake when selecting gear with vehicle stationary"
Symbol
also lights up in the selector lever cover until the brake pedal is actuated.
A time delay element ensures that the sele ctor 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 th e vehicle is stationary or moving at speed
of less than 5 km/h. The lock is swit ched off automatically into position N when the
car is travelling at a higher speed.

Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position) ⇒fig. 124 . 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 and 4 into
the next higher gear just before the maximum permissible engine speed is reached.
If you select a lower gear, the automatic ge arbox 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 th e 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. The
gearbox always shifts into 4th gear in the positions D, 4 , 3 and 2. 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.
