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 219,
“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 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selector lever is in position P. If the ignition key is withdrawn, the selector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 beyond the pressure point casues the
automatic gearbox to shift down into a lower gear (in line with vehicle
speed and engine speed). The gearbox shifts up into the next higher gear
when the engine has reached its maximum revolutions.
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 faster 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 operating the kickdown func-
tion, will cause the gearbox to switch over to the sporty driving
programme. Shifting up later into a higher gear makes it possible to fully
exploit the power reserves of the engine. The gearbox also then shifts
down at higher engine speeds than is the case for the economy-oriented
programmes.
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 into a sporty driving programme by depressing the
accelerator rapidly. The gearbox shifts down into a lower gear matching
the speed of the car and this allows you to accelerate rapidly (e.g. when
overtaking) without having to depress the accelerator pedal fully into the
kickdown range. The original programme will be reactivated to match your
particular style of driving once the gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and
downhill sections. This avoids the gearbox frequently shifting up and down
when negotiating an uphill stretch. Depressing the brake pedal while
driving downhill causes the gearbox to shift down into the next lower gear.
This makes it possible for you to exploit the engine braking power without
the need for shifting gears manually.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.

Switching over to manual shifting
– Push the selector lever to the right out of position D . As soon
as the gearbox has switched over, 5 4 3 2 1 appears in the
display, with the gear engaged being highlighted.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic posi- tion) ⇒page 135, fig. 125 .
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 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 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.
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.

Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake
system. The level of the brake fluid is monitored electronically
⇒page 36,
“Brake system ”.
WARNING
•Only apply the brakes for the purpose of drying and cleaning the
brake discs if the traffic conditions permit this. Do not place any
other road users in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs
etc. one must ensure that the air supply to the front wheel brakes
is not reduced otherwise the braking system could run too hot.
•Allow for the fact that new brake pads do not achieve their full
braking efficiency until approximately 200 kilometres. New brake
pads must be first “run in” before they develop their optimal fric-
tion force. You can, however, compensate for this slightly reduced
braking force by increasing the pressure on the brake pedal. This
guideline also applies to any new brake pads installed at a future
date.
Caution
•Never allow the brakes to rub by applying slight pressure if you do not
wish to brake the vehicle. This causes the brakes to overheat and can also
result in a longer braking distance and excessive wear.
•Before negotiating a steep downhill section, please reduce your
speed, shift down into the next lower gear (manual gearbox) or select a
lower driving stage (automatic gearbox). This enables you to make full use
of the braking power of the vehicle and reduces the strain on the brakes.
Any additional braking should be done intermittently, not continuously.
Brake booster
The brake booster boosts the pressure which you generate with the brake
pedal. The necessary pressure is only generated when the engine is
running.
WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running.
Greater physical effort for braking is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
Antilock brake system (ABS)
ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your
vehicle. Compared to a car not fitted with the ABS brake system, you are
able to retain optimal steering ability even during a full brake application
on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter
under all circumstances as a result of the ABS. The braking distance for
example on gravel and fresh snow, when you should anyway be driving
slowly and cautiously, will be longer.

Driving and the Environment
The first 1 500 kilometres and then
afterwards
A new engine
The engine has to be run in during the first 1 500 kilome-
tres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear
in use, that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the
full speed of the gear engaged, that is up to the maximum
permissible engine revolutions.
During the first operating hours the engine has higher internal friction than
later until all of the moving parts have harmonized. The driving style which
you adopt during the first 1 500 kilometres plays a decisive part in the
success of running in your car.
You should not drive at unnecessarily high engine revolutions even after
the running-in period is complete. The maximum permissible engine speed is marked by the beginning of the red zone on the scale of the revo-
lutions counter. Shift up into the next higher gear on a vehicle fitted with
manual gearbox before the red zone is reached.
Extremely high engine
revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also
applies: Do not drive at engine revolutions which are too low. Shift down
as soon as the engine is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is
at its normal operating temperature. Never rev up an engine which is cold,
neither when the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a
higher gear as early as possible are ways to minimise fuel consumption
and operating noise levels and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
You should take account of this fact for the first 500 kilometres and drive
particularly carefully.

Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first
gear. Always shift up into the next higher gear at approx. 2 000
to 2 500 revs.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it
beyond the kickdown position, however.
An effective way of achieving good fuel economy is to shift up early. You
will consume more fuel if you drive at unnecessarily high revolutions in
any given gear. The
⇒fig. 166 shows the ratio of fuel consumption to the speed of your
vehicle for the individual gears. Fuel consumption in 1st gear is the
highest, while that in 5th or the 6th gear is the lowest.
Only depress the accelerator pedal slowly if your vehicle is fitted with an
automatic gearbox in order to automatically select an economic driving
programme. You will achieve good fuel economy by shifting up early and
shifting down late. This applies in particular if you make use of the manual
mode (Tiptronic) for shifting gears.
Note
Also use the information supplied by the multi-functional indicator
⇒ page 18.
Avoiding full throttle
Driving more slowly means saving fuel.

lock - bonnet do not press down on it!
The bonnet is held in the opened position by a pressurized gas spring.
WARNING
•Never open the bonnet if you see that steam or coolant is
flowing out of the engine compartmen t - risk of scalding! Wait long
enough until the steam or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed
when driving. One should therefore check that the lock has in fact
engaged properly after closing the bonnet.
•Stop your vehicle immediately while driving if you notice that
the lock is not properly engaged and close the bonnet properly -
risk of an accident!
Caution
•Never open the bonnet using the handle - danger of causing damage.
•Before opening the bonnet, ensure that the arms of the windscreen
wipers are correctly in place against the windscreen. Otherwise, there is
a risk of damage to the paintwork.
Working in the en gine compartment
Particular care is required when carrying out any work in
the engine compartment!
There is a risk of injuries, scalding , accidents and fire when working
in the engine compartment, e.g. inspecting and replenishing oil and
other fluids. For this reason, it is essential to comply with the warning instructions stated below and with the general applicable
rules of safety. The engine compartment of your car is a hazardous
area
⇒ .
WARNING
•Never open the bonnet if you see that steam or coolant is
flowing out of the engine compartment - risk of scalding! Wait long
enough until the steam or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a manual gearbox, move the gear-
shift lever into Neutral, or if it is fitted with automatic gearbox, move
the selector lever into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Do not touch any hot engine parts - risk of burns!
•Never spill oil and other fluids over the hot engine. Such fluids
(e.g. the antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the
battery.
•Never place your hand into the radiator fan as long as the
engine is still warm. The fan might suddenly start running!
•Never open the cap of the coolant expansion bottle as long as
the engine is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a
large cloth when opening it as protection for your face, hands and
arms from hot steam or hot coolant.

Changing a wheel
Preliminary work
The following steps should be carried out before actually
changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose
should be level.
– Have all the occupants get out. While changing a wheel, the
occupants of the vehicle should not stand on the road (e.g.
behind a crash barrier).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic
gearbox, position the selector lever into position P .
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 247
out of the luggage compartment.
WARNING
•If you find yourself in flowing traffic switch on the hazard
warning lights system and place the warning triangle on the side of
the road at the prescribed distance from your vehicle while
observing all national legal provisions. In this way you are
protecting not only yourself but also other road users.
•Never start the engine with the vehicle sitting on the raised jack
- danger of suffering injury!
Caution
If you have to change a wheel on a slope first block the opposite wheel
with a stone or similar object in order to secure the vehicle from unexpect-
edly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 249 or the caps
⇒ page 251.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 250.
– Slacken the wheel bolts ⇒page 251.
