drivers.
Note
•
The turn signals only work when the ignition is switched on. The corre-
sponding warning lamp
or flashes in the combi-instrument. The
warning lamp
flashes when the turn signals are operated, provided a
trailer is correctly attached and connected to the vehicle. If a turn signal bulb
is defective, the warning lamp flashes at double speed. If the trailer turn
signal bulbs are damaged, warning lamp
does not light up. You should
have the bulb replaced.
•
The main beam headlights can only be switched on if the dipped beam
headlights are already on. The warning lamp
then comes on in the combi-
instrument.
•
The headlight flasher comes on for as long as you pull the lever – even if
no other lights are switch ed on. The warning lamp
then comes on in the
combi-instrument.
•
When the parking lights are switched on, the headlight and the rear light
on the corresponding side of the vehicle light up. The parking lights will only
work if the key is removed from the igni tion. If the lights are switched on, a
buzzer gives an audible warning while the driver door is open.
•
If the turn signal lever is left on after the key has been taken out of the
ignition lock, an acoustic signal sounds when the driver door is opened. This
is a reminder to switch off the turn signal, unless of course you wish to leave
the parking light on.

Driving
158Driving programmes
The automatic gearbox / direct shift gearbox (DSG) has three
programmes.Selecting the economic programme
– This programme selects a higher gear earlier rather than remain
in a lower gear.
– Put the selector lever into position D to drive forwards
– Put the selector lever into position R to reverse. This position is
shared by all programmes for reversing.
Selecting the sport programme
– Move the lever to position S.If you select the sport programme, S, the programme is designed for a sports
mode, that is, a programme which changes up at higher engine speeds to use the full power of the engine. This pr
ogramme is not recommended for use on
the motorway or in the city.
Selecting manual programme (tiptronic)
This programme allows the vehicle to be driven as if with a manual gearbox.
This programme may be accessed using the selector lever or from the
steering wheel controls when t his option it is fitted ⇒page 161.
Selector lever locking
The selector lever lock prevents gears from being engaged
inadvertently, which would cause the vehicle to move.Releasing the selector lever lock
–Start the vehicle.

Using the Tiptronic gear system
The Tiptronic system allows th e driver to manually select
gears
General points about the Tiptronic gear system
Changing gear with the selector lever
– Put the lever in the position D and press towards the right to
enter the Tiptronic gate ⇒fig. 122.
– Press the gear lever forwards (+) to select a higher gear.
– Press the gear lever back (-) to select a lower gear.
Changing gear using the steering wheel levers
– Press the right lever (+) towards the steering wheel to change up ⇒fig. 123.
– Press the left lever (-) towards the steering wheel to change down ⇒fig. 123.The manual programme can be selected with the levers on the steering wheel
irrespective of the driving mode which has been preselected.
General points about the Tiptronic gear system
When accelerating, the automatic/DSG gearbox automatically shifts up to the
next gear shortly before the maximu m permitted engine speed is reached.
If a lower gear is selected, the automatic gearbox / direct shift gearbox does
not change down until the point is re ached where the engine could no longer
overrev.
If the “tiptronic” is selected whilst the vehicle is in motion and the automatic
gearbox / direct shift gearbox is in the 3rd gear in selector lever position D,
the “tiptronic” will then also be in the 3rd gear.

The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann
ot defy the laws of physics. This
should be kept in mind, particular ly 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. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•
In order to ensure that TCS function 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.
•
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation program (ESP)*General notes
The electronic stabilisation program increases the vehicle's
stability on the road.The electronic stabilisation program helps to reduce the danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS. Electronic Stabilising Program (ESP)*
ESP reduces the danger 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 vehi
cle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
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.

Checking and refilling levels
216Ty re s e r vi ce l i fe
The service life of tyres is dependent on tyre pressure, driving
style and fitting.
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ fig. 151 running across the tread. Depending on the make, there will be six
to eight 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 215.
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 advisable
to change them around as shown ⇒fig. 152 . All the tyres will then last for
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 results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
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 align-
ment checked by an Authorised Service Centre.

Compact temporary spare wheel*
The compact temporary spare wheel (spare wheel for vehicles
with no puncture repair kit) should only be used when really
necessary.The temporary spare wheel is stored under the floor panel in the luggage
compartment and is attached by a thumbnut.
How to use the compact temporary spare wheel
Should you ever have a punctured tyre, the compact temporary spare wheel
is only intended for temporary use until you can reach a workshop. The
standard-size road wheel should be replaced as soon as possible.
Please note the following restrictions when using the compact temporary
spare wheel. This spare wheel has been specially designed for your vehicle,
thus, it cannot be changed with th e spare wheel from another vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim. Snow chains
For technical reasons, snow chains must not
be used on the compact tempo-
rary spare wheel.
If you should have a puncture on one of the front wheels when using snow
chains, fit the compact temporary spare in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and use
this wheel to replace the punctured front wheel.
WARNING
•
The tyre pressures must be checked and corrected as soon as possible.
The tyre pressure for the spare wheel is 4.2 bar. Failure to do so could result
in an accident.
•
Do not drive faster than 80 km/h. High er speeds can cause an accident.
•
Avoid heavy acceleration, hard braking and fast cornering, risk of acci-
dent.
•
Never use two or more compact spare tyres at the same time, risk of
accident.
•
No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.Note
•
Emergency wheels must never be used on vehicles fitted with Brembo
brakes. These vehicles are supplied with a tyre repair kit.
Tyre repair kit*
The tyre repair kit (for vehicles not including a spare wheel) is
stored under the floor panel in the luggage compartment.Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.

If and when
224The tyre repair kit consists of a container with sealing compound to repair the
puncture and a compressor to generate the required tyre pressure. The kit will
reliably seal punctures up to a size of about 4 mm caused by the penetration
of a foreign body into the tyre.
Note
•
Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.
Wheel changePreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the vehicle as far away from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the ve hicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
–Apply the handbrake firmly.
– Engage the first gear, or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle. –Take the
vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in position.
This is for your own safety and also warns other road users.
Caution
If you have to change the wheel on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.Changing a wheelChange the wheel as described below
–Pull off the hub cap. See ⇒ page 225, fig. 154.
– Slacken the wheel bolts
– Raise the car with the jack in the corresponding zone
– Ta k e o f f the wheel and then put on the spare wheel
– Lower the vehicle.
