WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also result in death.
● Never leave the vehicle unattended if the engine is running.
● Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.
CAUTION
● When the engine is cold, you should avoid high engine speeds, driving
at full throttle and over-loading the engine. Risk of engine damage.
● The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.
● Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and fol-
low the instructions in ⇒ page 287, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. You should drive off as soon as you start the engine. This helps the en-
gine reach operating temperature faster and reduces emissions. 
Switching off the engine
– Stop the vehicle.
– Turn the ignition key to position ⇒ Fig. 140 0
.
After switching the engine off, the radiator fan may run on for up to 10 mi-
nutes. It is also possible that the fan turns itself on once more if the coolant temperature increases due to the heat accumulated in the engine compart-
ment or due to its prolonged exposure to solar radiation.
WARNING
● Never switch the engine off until the vehicle is completely stationary.
● The brake servo works only when the engine is running. With the en-
gine switched off, more strength is needed to brake. As normal brake op-
eration cannot be performed, risk of accidents and serious injury may ex-
ist.
● The steering lock can be immediately blocked once the key is re-
moved from the ignition. The vehicle cannot be steered. Risk of accident.
CAUTION
When the engine has been running under a heavy load for a long period,
heat can accumulate in the engine compartment and cause engine damage.
For this reason, you should idle the engine for approx. 2 minutes before you
switch it off. 

WARNING (Continued)
● The footbrake must not be held for a long period of time, not even
lightly; continuous braking will cause overheating of the brakes and a re-
duction or even a loss of braking power and a significant increase in
braking distances.
● Never allow the vehicle to coast down a gradient with the selector lev-
er in positions N or D, even when the engine is not running. For descents,
the use of the tiptronic programme is recommended to keep the speed
reduced.
CAUTION
● Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause dam-
age. Apply the handbrake or depress the foot brake to hold the vehicle in
position.
● If the vehicle is allowed to roll with the engine stopped but the selector
in position N then the gearbox may be damaged because it will not be lubri-
cated. Changing gear in tiptronic mode*
The tiptronic system allows the driver to select gears man-
ually

Driving
Changing gear with the selector lever
– Put the lever in position D and press towards the right to enter
the tiptronic gate ⇒ Fig. 150.
– Press the gear lever forwards +
⇒ Fig. 150 to select a higher
gear.
– Press the gear lever back –
⇒ Fig. 150 to select a lower gear.
Changing gear with the steering wheel levers
– Press the right paddle lever +
(+OFF) towards the steering
wheel to change up ⇒ Fig. 151.
– Press the left paddle –
towards the steering wheel to change
down ⇒ Fig. 151.
Using the paddle levers on the steering wheel, you can access manual driv-
ing mode regardless of the pre-selected driving mode.
General information about driving in tiptronic mode
When accelerating, the automatic gearbox / DSG automatic gearbox goes
into a higher gear a little before the engine reaches its maximum permitted
revolutions.
If a lower gear is selected, the automatic gearbox / DSG automatic gearbox
will only change down when the engine cannot go over its maximum permit-
ted revolutions.
If tiptronic is selected whilst the vehicle is in motion and the automatic
gearbox / DSG automatic gearbox is in third gear and selector lever position
D, tiptronic mode will then also be in third gear.
Changing gears in the normal or sport programme using the steering wheel
paddle levers
If the paddle levers ⇒ Fig. 151 are used in the normal or sport programme,
the system switches temporarily to tiptronic mode. To exit tiptronic mode again, press the right paddle lever
+ OFF
towards the steering wheel for ap-
proximately one second. You will also leave “Tiptronic” mode if the paddle
levers are not moved for a certain time.
Note
● The gearbox controls on the steering wheel can operate with the selector
lever in any position and with the vehicle in motion. 
Kick-down feature
This feature allows maximum acceleration. If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and engine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.
● Be particularly careful when using the kick-down features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction
and skid.
● You should use the kick-down feature only when traffic and weather
conditions allow it to be used safely.

Driving
– Apply the handbrake.
– Select first gear.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you keys with you when you leave the vehicle ⇒ 
.
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.
● If the vehicle is parked facing downhill, turn the front wheels so that
they point towards the kerb .
● If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .
● Secure the vehicle as normal by applying the handbrake firmly and se-
lecting first gear.
WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle unattended.
● Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to vehicle occupants.
● Never leave children alone in the vehicle. They could set the vehicle
in motion, for example, by releasing the handbrake or the gearbox lever.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.
 Hill driving assistant*
This function is only included in vehicles with ESC.
The hill driving assistant helps the driver to move off and upwards on a hill
when the vehicle is stationary.
The system maintains brake pressure for approximately two seconds after
the driver takes his foot off the brake pedal to prevent the vehicle from
lurching backwards when it is started. During these two seconds, the driver
has enough time to release the clutch pedal and accelerate without the ve-
hicle moving and without having to use the handbrake, making start-up
easier, more comfortable and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● closed doors,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in neutral for manual gear
change and with the selector lever at positions S, D or R in vehicles with au-
tomatic gearbox.
This system is also active in reversing uphill.
WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the hand brake immediately.
● If the engine stalls, depress the brake pedal or use the hand brake
immediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off. 

Intelligent technology
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESC. This function
aids the driver to better stabilize the vehicle in a critical situation. For exam-
ple, in case of sudden braking surface with varied adherence, the vehicle
will tend to destabilise its trajectory to the right or to the left. In this case,
the ESC recognises the situation and assists the driver with a counter steer-
ing manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
● Remember that not even the ESC can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
CAUTION
● To ensure that the ESC works correctly, all four wheels must be fitted
with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR. 
Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 197. 
Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The system will control the revolutions of the driven wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 83.
At speeds of up to approximately 80 km/h, it is able to balance out differen-
ces in the speed of the driven wheels of approximately 100 rpm caused by a
slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the oth-
er driven wheel via the differential. 

WARNING
● Apply the brakes heavily to clean the brake system only in a suitable
traffic situation. Be sure not to inconvenience or endanger other road
users. Risk of accident.
● Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.
CAUTION
● Never let the brakes “drag” by leaving your foot on the pedal when it is
not necessary to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.
● Before driving down a long, steep gradient, it is advisable to reduce
speed and change to a lower gear (or move the gear lever to a lower gear
position if your vehicle has an automatic gearbox). This makes use of en-
gine braking and prolongs the useful life of the brakes. If you still have to
use the brakes, it is better to brake firmly at intervals than to apply the
brakes continuously.
Note
● If the brake servo is not functioning due to a malfunction, or if the vehi-
cle has to be towed, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.
● If you wish to equip the vehicle with accessories such as a front spoiler
or wheel covers, it is important that the flow of air to the front wheels is not
obstructed, otherwise the brakes can overheat. Power steering (servotronic*)
Power steering makes it easier to turn the steering wheel
when the engine is running.
Power steering assists the driver by reducing the force needed to turn the
steering wheel. In cars equipped with servotronic* power steering the de-
gree of power assistance is regulated electronically according to road
speed.
The power steering will keep on working even if the servotronic* device
fails. The degree of power assistance will, however, no longer adapt to dif-
ferent speeds. If the electronic regulating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking), as more effort will be required than usual. The fault
should be corrected by a specialised workshop as soon as possible.
Power steering does not work if the engine is off. In this case the steering
wheel requires much more force to turn.
If the steering is held at its turning limit when the vehicle is stationary, this
will place an excessive load on the power steering system. Turning the
steering wheel to its limit places a load on the system, which causes noise.
It will also reduce the idling speed of the engine.
CAUTION
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering. 

203
Intelligent technology
Note
● If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the vehicle can still be steered. However,
more effort will be required to turn the steering wheel.
● If the system is leaking or malfunctioning, please take the vehicle to a
specialised workshop as soon as possible.
● The power steering system requires a special hydraulic fluid. The con-
tainer is located in the engine compartment (front left). The correct fluid lev-
el in the reservoir is important for the power steering to function properly.
The hydraulic fluid level is checked at the Inspection Service. 

256Wheels and tyres
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 176, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 253.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 177. The useful life of all the
tyres will then be about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted. Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 256. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by a Technical Service.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 
