The engine can only be started using a correctly coded original key.
The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem.
WARNING■ When the vehicle is travelling with the engine off, the ignition key must
always be in position 2 » Fig. 134 on page 139 (ignition switched on). This
position is confirmed by the appearance of certain indicator lamps in the in-
strument cluster. ■If the key is not in position 2,
it could unexpectedly lock the steering -
danger of accident!
■
Only pull the ignition key from the ignition lock when the vehicle has
come to a complete stop (by applying the handbrake). Otherwise, the steer-
ing could be blocked – risk of accident!
■
Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!
■
Never leave the vehicle unattended with the engine running - there is
risk of accident, damage or theft!
■
Never switch off the engine before the vehicle is stationary – risk of acci-
dent!
WARNING■ Never leave the engine running in unventilated or closed rooms. The en-
gine's exhaust gases also contain the odourless and colourless carbon
monoxide, a poisonous gas – risk of death. ■ Carbon monoxide can cause unconsciousness and death.■
Do not leave any items (e.g. cleaning cloths or tools) in the engine com-
partment. This presents a fire hazard and the risk of engine damage.
■
Never cover the engine with additional insulation material (e.g. with a
cover) – risk of fire!
CAUTION
■ The starter must only be operated when the engine is not running and the
vehicle is at a standstill. The starter or engine can be damaged if the starter is
activated when the engine is running 3
» Fig. 134 on page 139 .
■
Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-
start aid » page 211 , Jump-starting .
CAUTION
■
Avoid high engine revolutions, full throttle and high engine loads before the
engine has reached its operating temperature – risk of damaging the engine!■
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumula-
tion of heat when the engine is switched off.
For the sake of the environment
Do not warm up the engine while the vehicle is stationary. If possible, start
your journey as soon as the engine has started. Through this the engine rea-
ches its operating temperature more rapidly and the pollutant emissions are
lower.
Note
After switching off the ignition, the radiator fan can intermittently continue to
operate for approx. 10 minutes.138Driving
Electronic immobilizerRead and observe
and on page 138 first.
An electronic chip is integrated in the head of the key. The immobiliser is deac-
tivated with the aid of this chip when the key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the ignition key is
withdrawn from the lock.
The engine will not start if a non-authorized ignition key is used.

Brakes
Introduction
This chapter contains information on the following subjects:
Information on braking
143
Handbrake
144WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
The clutch pedal must be depressed when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the function of the brake booster may be impaired – risk of accident!
■
When leaving the vehicle, never leave persons who might, for example,
release the handbrake or take the vehicle out of gear unattended in the ve-
hicle. The vehicle could then start to move – risk of accident!
WARNINGIn the case of damage to the standard fitted front spoiler or if retrofitting
another front spoiler, hub caps etc. » page 173, Services, modifications and
technical alterations , make sure that the air supply to the front brakes is
not affected. The front brakes may overheat, which can have a negative im-
pact on the functioning of the braking system – there is a risk of an acci-
dent!CAUTION■ Observe the recommendations on the new brake pads » page 149.■Never let the brakes slip with light pressure on the pedal if braking is not
necessary. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
Information on braking
Read and observe
and on page 143 first.
If the brakes are applied in full and the control unit for the braking system con-siders the situation to be dangerous for the following traffic, the brake light
flashes automatically.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af- ter accelerating or driving off again.
Before travelling a long distance down a steep gradient, reduce speed and
shift into the next lowest gear. As a result, the braking effect of the engine will
be used, reducing the load on the brakes. Any additional braking should be
completed intermittently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv- ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
Under these severe conditions , the thickness of the brake pads must also be
checked by a specialist garage between services.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the brake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned by applying the brakes several times.
143Starting off and Driving
Fig. 140
Shift lock button
Read and observe and on page 145 first.
When the ignition is switched on, the gearbox mode and the currently selectedgear are indicated in the display » Fig. 139.
The following modes can be selected with the selector lever » Fig. 139.
P
– Parking mode
The driven wheels are locked mechanically in this mode.
Parking mode must only be selected when the vehicle is stationary.
R
- Reverse gear
Reverse gear can only be engaged when the vehicle is stationary and the en-
gine is at idling speed.
Before moving into mode R from mode P or N, depress the brake pedal while
simultaneously pressing the lock button in the direction of the ar-
row » Fig. 140 .
N
- Neutral
Power transmission to the drive wheels is interrupted in this mode.
D
- Mode for forwards travel (normal programme)
In mode D, the forward gears are automatically changed according to the en-
gine load, accelerator pedal actuation and driving speed.
S
- Mode for forwards travel (sports programme)
In mode S, the forward gears are shifted automatically up and down at higher
engine speeds than in mode D.
Before changing to mode S from mode D , the shift lock button must be press-
ed in the direction of the arrow » Fig. 140.
Releasing selector lever from P or N modes (selector lever lock)
The selector lever is locked in the P and N modes to prevent the forwards trav-
el mode from being selected accidentally and setting the vehicle in motion.
The
warning light illuminates in the instrument cluster » page 41.
The selector lever is released by depressing the brake pedal while simultane-
ously pressing the lock button in the direction of the arrow » Fig. 140.
The selector lever is not locked when shifted quickly through N (e.g. from R to
D ). This, for example, helps to rock out a vehicle that is stuck, e.g. in a bank of
snow. The selector lever lock will engage if the lever is in position N for more
than approximately 2 seconds without the brake pedal being depressed.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
Note
If you want to move the selector lever from mode P to mode D or vice versa,
move the selector lever quickly. This prevents modes R or N from being selec-
ted accidentally.
Manual gear shifting (Tiptronic)
Fig. 141
Selector lever/multi function steering wheel
Read and observe
and on page 145 first.
Tiptronic mode makes it possible to manually shift gears with the selector lev-
er or multifunction steering wheel. This mode can be selected both while hal-
ted and while driving.
The currently selected gear is indicated in the » Fig. 139 on page 145 display.
The gearshift indicator must be observed when changing gear » page 43.

Manual gear shifting is deactivated if more than 1 minute passes after either of
the -
/+ paddles was pulled. The temporary switch to manual gear shifting can
also be deactivated by pulling the right-hand + paddle towards the steering
wheel for more than 1 second.
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached.
If a lower gear is selected, the gearbox does not shift down until there is no risk of the engine over revving.
Note
It may be beneficial, for example, when travelling downhill, to use manual
shifting of gears. Shifting to a lower gear reduces the load on the brakes and
hence brake wear » page 143.

156WARNING■ A lack of fuel can cause irregular engine running or cause the engine to
shut down. The brake assist systems would then fail to function – risk of
accident!■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions. The increased safety provided by the brake assist
systems must not tempt you to take safety risks – risk of accident!
■
In the event of an ABS fault, visit a specialist garage immediately. Adjust
your style of driving according to the damage to the ABS, as you will not
know the exact extent of the damage or the extent to which this is limiting the braking efficiency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufac-
turer to ensure the brake assist systems operate correctly.■
Changes to the vehicle (e.g. to the engine, brakes, chassis) can influence the
functionality of the brake assist systems » page 173, Services, modifications
and technical alterations .
■
If a fault occurs in the ABS system, the ESC, ASR and EDL will also not work.
An ABS fault is indicated with the warning light
» page 38 .
Electronic Stability Control (ESC)Fig. 146
ESC system: ASR button
Read and observe and on page 154 first.
The ESC system helps to maintain control of the vehicle in situations where it
is being operated at its dynamic limits, such as a sudden change to the direc-
tion of travel. Depending on the road surface conditions, the risk of skidding is
reduced, thereby improving the vehicle's driving stability .
The ESC system is automatically activated each time the ignition is switched on.
The direction which the driver wishes to take is determined based on the
steering angle and the speed of the vehicle and is constantly compared with
the actual behaviour of the vehicle. If differences exist, such as the car begin-
ning to skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light flashes in the instru-
ment cluster.
The following systems are integrated into the Electronic Stability Control
(ESC) .
