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.

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.

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

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 .

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.

The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle phase, e.g. when stopped at traffic lights. The engine restarts automatically
where necessary.
The system can work only if the following basic conditions are met. The driver's door is closed.
The driver has fastened the seat belt. The bonnet is closed.The driving speed exceeded 4 km/h after the last stop.
No trailer is coupled.
WARNING■ The brake servo unit and power steering only operate if the engine is run-
ning.■
Never let the vehicle roll with the engine switched off.
CAUTION
Always deactivate the START-STOP system before driving through wa-
ter » page 109 .Note■
If the driver's seat belt is removed for more than 30 seconds or the driver's door
is opened during stop mode, the engine will have to be started manually.■
After manually starting the engine, automatic engine shut down is not possible
until the vehicle has travelled the required minimum distance for START-STOP mode.
■
Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out-
doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable
temperature for proper operation of the START STOP system.
■
If Climatronic is running in automatic mode, the engine may not switch off auto-
matically under certain conditions.

The specified safety equipment works together, in order to optimally protect you
and those travelling with you in accident situations.
The safety equipment does not protect you or the people travelling with you, if
you or your occupants adopt an incorrect seated position or the equipment is not
correctly adjusted or used.
If the seat belt is not fastened properly, this may result in injuries during an acci-
dent caused by the deployed airbag.
Before every journey
First read and observe the introductory information and safety warn-ings
on page 124.
For your own safety and the safety of the people travelling with you, please pay
attention to the following points before setting off.
› Ensure that the lighting and the turn signal system are functioning properly.
› Check the tyre inflation pressure.
› Ensure that all of the windows offer good visibility to the outside.
› Secure all items of luggage
» page 58.
› Ensure that no objects can obstruct the pedals.
› Adjust the mirrors, the front seat and head restraint to your body size.
› Advise your passengers to adjust the head restraints to their body size.
› Protect children in suitable child seats with correctly fastened seat
belts » page 140 , Transporting children safely .
› Adopt the correct seated position

124Safety
What influences driving safety?First read and observe the introductory information and safety warn-
ings
on page 124.
The driver is fully responsible for himself and his occupants. If your driving safety is effected, you place yourself and the oncoming traffic at risk.
The following guidelines must therefore be observed. › Do not get distracted from concentrating on the traffic situation, e.g. by your
passengers or mobile phone calls.
› Never drive when your driving ability is impaired, e.g. through medication, alco-
hol or drugs.
› Keep to the traffic regulations and the permissible speed limit.
› Always adjust the driving speed to the road, traffic and weather conditions.
› Take regular breaks on long journeys – at least every two hours.
Correct seated position
Introduction
This chapter contains information on the following subjects:
Correct seated position of the driver
126
Correct seated position of the front passenger
126
Correct seated position of the rear seat passengers
126
Examples of incorrect seated positions
126WARNINGGeneral information■The front seats and head restraints must be adjusted to match the body
size at all times and the seat belt must always be fastened properly to provide the most effective levels of protection to the passengers.■
If the occupant adopts an incorrect seated position, he is exposed to life-
threatening injuries, in case he is hit by a deployed airbag.
■
If the occupants on the rear seats are not sitting upright, the risk of injury is
increased due to incorrect routing of the seat belt.
■
The seat backrests must not be reclined too far when driving otherwise this
will affect proper operation of the seat belts and of the airbag system – risk of
injury.
WARNINGInformation for the driver■Always assume the correct seated position before setting off and do not
change this position while driving. Also advise your passengers to adopt the
correct seated position and not to change this position while the car is mov-
ing.■
Keep a distance of at least 25 cm from the steering wheel. Not keeping to
this minimum distance will mean that the airbag system will not be able to
properly protect you – risk of death.
■
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.
■
Ensure that there are no objects in the driver's footwell as they may get
caught behind the pedals while you are driving or under braking. You would
then no longer be able to operate the clutch, brake or accelerate.
WARNINGInformation for the front seat passenger■Maintain a distance of at least 25 cm from the dash panel. 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.■
Always keep your feet in the footwell when the car is being driven - never
place your feet on the instrument panel, out of the window or on the seats.
You will be exposed to increased risk of injury if it becomes necessary to apply
the brakes or in the event of an accident. You may suffer fatal injuries when
an airbag is deployed if you have adopted an incorrect seating position.
