Introduction
This chapter contains information on the following subjects:
Adjusting the steering wheel position
95
Power steering
95WARNING■ When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel in
the 12 o'clock position or in any other way (e.g. in the middle or inner edge of
the steering wheel). In such cases, you could severely injure your arms, hands
and head when the driver airbag is deployed.■
Never adjust the steering wheel when the vehicle is moving only when the
vehicle is stationary!
■
Adjust the steering wheel so that the distance
1
» Fig. 85 on page 95
between the steering wheel and your chest is at least 25 cm. Not maintaining
this minimum distance will mean that the airbag system will not be able to
properly protect you - there is a risk that you could be killed.
■
If the steering wheel is adjusted further towards the head, the protection
provided by the driver airbag in the event of an accident is reduced. Check
that the steering wheel is aligned to the chest.
Adjusting the steering wheel positionFig. 85
Adjustable steering wheel: Lever below the steering column/safe
distance to the steering wheel
First read and observe the introductory information and safety warn-
ings
on page 95.
The height and forward/back position of the steering wheel can be adjusted.
›
First of all adjust the driver's seat » page 54, Front seats .
›
Pull the lever below the steering wheel down » Fig. 85 -
.
›
Adjust the steering wheel to the desired position (with regard to the height and
forward/back position).
›
Push the lever upwards to the stop.
WARNINGThe lever for adjusting the steering wheel must be locked while you are driv- ing so that the position of the steering wheel cannot accidently change duringthe journey – there is the risk of an accident.
Power steering
First read and observe the introductory information and safety warn-ings
on page 95.
The power steering enables you to steer the vehicle with less physical force.
The power steering only works when the engine is running.
95Starting-off and Driving

It is still fully possible to steer the vehicle if the power steering fails or if the en-gine is not running (e.g. when towing). However, greater physical effort is re-
quired to turn the steering wheel.
CAUTION
You will place great stresses on the power steering system if the steering is
turned to full lock when the vehicle is stationary. Turning the steering to full lock
in such a situation will be accompanied by noises. Never leave the steering wheel at full lock for more than 15 seconds when the engine is running - there is a risk of
damaging the power steering.
Starting and stopping the engine

Starting the engine
97
Switching off the engine
98
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 afterstarting 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 al-
ways be in position 2 » Fig. 86 on page 97 (ignition switched on). This posi-
tion is indicated by the warning lights coming on. If this is not the case, it
could result in unexpected locking of the steering wheel – there is the risk of
an 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 steering wheel
could lock – there is the risk of an accident.
WARNING (Continued)■ When leaving the vehicle, the ignition must always be removed. This is par-
ticularly important if children are left in the vehicle. Otherwise the children
could, for example, start the engine – there is the risk of an accident or injury.■
Never leave the vehicle unattended with the engine running.
■
Never switch off the engine before the vehicle has come to a halt – there is
the risk of an accident.
WARNING■ Never leave the engine running in unventilated or closed rooms. The en-
gine's exhaust gases also contain the odourless and colourless carbon mon-
oxide, a poisonous gas – risk of death. ■ Carbon monoxide can cause unconsciousness and death.
CAUTION
■The starter must only be operated when the engine is not running and the vehi-
cle is at a standstill. The starter or engine can be damaged if the starter is activa-
ted when the engine is running 3
» Fig. 86 on page 97.
■
If the engine does not start up after a second attempt, the fuse for the fuel
pump may have a fault. Check the fuse and replace, if necessary » page 192 or
seek assistance from a specialist garage.
■
Let go of the ignition key as soon as the engine starts otherwise the starter
could be damaged.
■
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 187 , Jump-starting .
CAUTION
■
Avoid high engine speeds, full throttle and high engine loads until the engine
has yet reached its operating temperature – there is a risk of damaging the en-
gine.■
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 accumulation
of heat when the engine is switched off.
96Driving

For the sake of the environmentDo 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 reaches its operating temperature more rapidly and the pollutant emissions are lower.
Note
The radiator fan can intermittently continue to run for approximately 10 minutes
after the ignition has been switched off.
Electronic immobilizer
First read and observe the introductory information and safety warn-ings
on page 96.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated 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 with-
drawn from the lock.
The engine will not start if a non-authorized ignition key is used. The MAXI DOT display shows the following:
Immobilizer active.

Note
We recommend locking the steering wheel whenever leaving the vehicle. This
acts as a deterrent against the attempted theft of your car.
Starting the engine
First read and observe the introductory information and safety warn-
ings
on page 96.
Vehicles with a diesel engine are equipped with a glow plug system. The glow
plug warning light
lights up after the ignition has been switched on. Start the
engine once the
warning light has gone out.
You should not switch on any major electrical components during the heating pe- riod otherwise the vehicle battery will be drained unnecessarily.

Brakes
Introduction
This chapter contains information on the following subjects:
Information for braking
98
Handbrake
99WARNING■ Greater physical effort is required for braking when the engine is switched
off – there is the risk of an accident.■
The clutch pedal must be depressed when braking on a vehicle with manual
transmission, when the vehicle is in gear and at low revs. If you fail to do so, the functionality of the brake servo can be impaired – there is the risk of an
accident.WARNING (Continued)■ If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must be
ensured that the air supply to the front wheel brakes is not reduced. The front
brakes may overheat, which can have a negative impact on the functioning of
the braking system – there is a risk of an accident.■
Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle might then move off – there is the risk of an accident.
CAUTION
■ Observe the recommendations on the new brake pads » page 104.■Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
Information for braking
First read and observe the introductory information and safety warn-
ings
on page 98.
If the brakes are applied in full and the control unit for the braking system consid-
ers 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 stopped,
the brake light stops flashing and the hazard warning light system switches on.
The hazard warning light system is switched off automatically after 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 comple-
ted intermittently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving 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.
98Driving

CAUTION■If the selector lever is shifted to N while the vehicle is being driven you must lift
off the accelerator pedal and you will need to wait until the engine has reached
its idling speed before shifting the selector lever to a forward driving mode again.■
At temperatures below -10 °C, the engine can only be started in selector lever
position P.
■
Never try to hold the vehicle using the accelerator pedal when stopping on a hill
– this may lead to transmission damage.
Note
The ignition key can only be withdrawn once the ignition has been switched off if
the selector lever is in the P position 1)
.
Modes and use of selector lever
Fig. 89
Selector lever /MAXI DOT display: Selector lever positions
First read and observe the introductory information and safety warn-
ings
on page 100.
When the ignition is switched on, the gearbox mode and the gear currently selec-
ted are indicated in the display
1
» Fig. 89 .
The following modes can be selected with the selector lever » Fig. 89.
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 engine
is at idling speed.
Depress the brake pedal and simultaneously press the shiftlock in the selector
lever grip before shifting to R from P or N.
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 engine
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 en-
gine speeds than in mode D.
The shiftlock on the selector lever grip must be pressed when moving the selec-
tor lever out of D mode into S mode.
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 travel
mode from being selected accidentally and setting the vehicle in motion. The
warning light lights up in the instrument cluster » page 27.
The selector lever is released by depressing the brake pedal while simultaneously
pressing the locking button in the selection lever grip.
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 ap-
proximately 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 selected acci-
dentally.1)

101Starting-off and Driving

Manual gear shifting (Tiptronic)Fig. 90
Selector lever/multi-function steering wheel
First read and observe the introductory information and safety warn- ings
on page 100.
Tiptronic mode makes it possible to manually shift gears with the selector lever or
multifunction steering wheel. This mode can be selected both while halted and
while driving.
The gear currently selected is indicated in the display
1
» Fig. 89 on page 101.
The gearshift indicator must be observed when changing gear » page 13.

›
Pull one of the -/+ paddles
» Fig. 90 briefly towards the steering wheel .
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 riskof the engine overrevving.
Note
It may be advantageous to use manual gear shifting when driving downhill, for
example. Shifting to a lower gear reduces the load on the brakes and hence brake wear » page 98 , Information for braking .

Assist systems
Brake assist systems
Introduction
This chapter contains information on the following subjects:
Stabilisation control (ESC)
111
Antilock Braking System (ABS)
112
Traction Control System (ASR)
112
Electronic Differential Lock (EDL and XDS)
112WARNING■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then be without function – there is the
risk of an accident.■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety offered by the brake assist systems
must not tempt you to take greater risks than otherwise – there is the risk of
an accident.
■
Visit a specialist garage immediately in the event of an ABS fault. Adjust
your style of driving according to the damage to the ABS as you will not know
how great the damage is and the limitation it is placing on the braking effi-
ciency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufactur-
er 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 147, Services, modifications and
technical alterations .
■
If a fault occurs in the ABS system, the ESC, TCS and EDL will also fail to work.
An ABS fault is indicated with by the warning light » page 24.
Stabilisation control (ESC)
First read and observe the introductory information and safety warn-ings
on page 111.
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 direction 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 beginning 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 stabilisation control
(ESC) :
› Antilock brake system (ABS),
› Traction control (TCS),
› Electronic Differential Lock (EDL and XDS);
› Hydraulic brake assist (HBA);
› Hill hold control (HHC).
The ESC system cannot be deactivated. The
» Fig. 96 on page 112 button can
only be used to deactivate the TCS. The
warning light comes on in the instru-
ment cluster when the TCS is deactivated.
In the event of an ESC fault, the ESC warning light illuminates in the instrument cluster
» page 23 .
Hydraulic brake assist (HBA)
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by very rapid depression of the brake pedal. To achieve the
shortest possible braking distance, the brake pedal must be applied firmly until
the vehicle has come to a complete standstill.
HBA is automatically switched off when the brake pedal is released. ABS is activated sooner and more effectively with the intervention of HBA.
