WARNING
•When driving, the ignition key must always be in the position
(ignition switched on) without the en gine 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 wheel - risk of
accident!
•Do not withdraw the ignition key from the lock until the car has
come to a stop. The steering lock can engage immediately - risk of
accident!
•Always withdraw the ignition key if you are going to leave the
vehicle, even for a short time. This is particularly important if chil-
dren are left in the vehicle. The children might otherwise start the
engine or operate electrical equi pment (e.g. power windows) - risk
of injury!
Starting the engine
General
You can only start the engine only using an original ignition
key.
•Place the gearshift lever into neutral 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 another vehicle as a jump-start aid
⇒
page 243.
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 247.
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 unconsciousness 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 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 249.
•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 249.
•Contact the nearest specialist garage to obtain professional assist-
ance.
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 off the engine
– The engine can be switched off by turning the ignition key from position ⇒page 110, fig. 100 into position .

WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•The brake booster only operates when the engine is running.
Greater physical effort for brakin g is required when engine 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 for 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 coolant temper-
ature rises because of an accumulation 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 210, “Working in the engine
compartment”.
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 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. 102 .
– 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 6
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 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 obstacle located behind the vehicle with the aid of ultrasound
sensors. 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. 103 ). 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. You should not reverse any further after this signal
sounds! Activating
The parking aid is activated automatically when
reverse gear is engaged
and the ignition is turned on. This is confirmed by a brief acknowledge-
ment signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for 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 post, 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*).
•A system fault is indicated if a warning signal sounds for about 5
seconds after switching the ignition on and engaging reverse gear and
there is no obstacle close to your vehicle. 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.
•If the parking aid is activated and the selector lever of the automatic
gearbox is in the position , warning signal indicates interruption (vehicle
can no longer move).

The brake pedal must be depressed and at the same time the Shiftlock
must be pressed, if you wish to obtain the selector lever positions
R, P or
N .
When the ignition is switched on and the selector lever is in position R, the
reverse lights will come on.
N - Neutral
The transmission is in Neutral in this position.
The brake pedal must be depressed (if the lever is in its position for longer
than 2 seconds) in order to move the selector lever out of the position N
into the position D, with the ignition switched on, on a vehicle travelling at
less than 5 km/hour or on a stationary vehicle.
The brake pedal must be depressed (if the lever is in its position for longer
than 2 seconds) in order to move the selector lever out of the position N
into the position R, with the ignition switched on, on a vehicle travelling at
less than 5 km/hour or on a stationary vehicle.
D - Drive, position for driving forward
When the selector lever is in this position, the forward gears are shifted up
and down automatically in line with engine load, vehicle speed and the
dynamic shift programme.
You must depress the brake pedal ⇒ if you wish to move the selector
lever into position D from N when the vehicle is travelling at less than
5 km/hour or is stationary.
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 123 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 interrupted, 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 210,
“Working in the engine compartment”.
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 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:
In addition, the symbol
for the automatic selector lever lock in the shift
gate lights up.
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 - 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.
Kickdown function
The kickdown function provides you with maximum accel-
eration power.
Depressing the accelerator pedal allows the kickdown function to be acti-
vated in the desired driving program. This function has precedence over
the driving programme and serves for maximum acceleration of the
vehicle when exploiting the maximum power potential of the engine without taking into account the current selector lever position (
D, S or
Tiptronic ). The gearbox shifts down to one or several gears in line with
the driving state and the vehicle accelerates. The gearbox does not shift
up into the highest gear until the engine has reached its maximum revolu-
tions for this gear range.
WARNING
Please note that using the kickdown function can result in the
driven wheels spinning on a smooth or slippery road surface - risk
of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting
up and down through the gears is performed automatically on the basis of
pre-defined driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the
most economical driving programme. Shifting up into a higher gear as
soon as possible and shifting down as late as possible will have a favour-
able effect on your fuel consumption.
Adopting a sporty style of driving with rapid movements of the acceler-
ator pedal combined with sharp acceleration and frequent changes in
speed, exploiting the top speed of the car or depressing the accelerator
pedal (kickdown function), will cause the gearbox to switch over to this
style of driving and shift down earlier with frequent changes in gears in
comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style
of driving is a continuous process. Irrespective of this it is, however,
possible to switch or shift down into a dynamic shift programme by
depressing the accelerator rapidly. The gearbox shifts down into a lower
NKO 20 A05.book Page 122 Wednesday, June 21, 2006 1:42 PM
Automatic gearbox
124
If you select a lower gear, the automatic gearbox does not shift down until
there is no risk of the engine overrevving. (Does not apply for the shifting
from 2nd to 1st gear.)
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 functional 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.
Selector lever-emergency unlocking
In case of interruption of the power supply (e.g. flat vehicle
battery, defective fuse) or defect of the selector lever lock, the
selector lever can no longer be shifted from the position P in the
normal way and the vehicle can no longer be moved. The
selector lever must be unlocked in case of emergency.
– Apply the handbrake firmly.
– Open the stowage compartment in front centre console* or the front ashtray.
– Carefully pull up the front left and right cover.
– Pull up rear cover.
– Press with a narrow object (e.g. ignition key) the yellow plastic hoop -arrow- to the left.
