Selector lever positions
The selected gear is displayed on the side of the selector lever and on the
instrument panel display. The currently selected gear for the automatic
gearbox will also be shown on the display.
Tiptronic gear indicator
If the automatic gearbox is shifted manually, the selected gears are shown
on the screen.
P - parking lock
When the selector lever is in this position, the driven wheels are locked me-
chanically.
Position P on the lever must only be selected if the vehicle is stationary.
To move selector lever from position P, the locking button on the selector
lever handle must be pressed and the brake pedal depressed at the same
time while the ignition is switched on.
To put the selector lever in position P, simply press the lock button down
and, if necessary, depress the brake pedal down.
R - Reverse gear
The reverse gear is engaged in this position.
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling.
To move the selector lever to position R, press the lock button down and, at
the same time, press the brake pedal down, with the ignition switched on.
With the selector lever in position R and the ignition switched on the follow-
ing occurs:
● Reverse lights light up.
● The air conditioner automatically changes the air recirculation mode. ●
The wiper starts if the windscreen washer is on.
● The parking distance warning system* switches on.
N - Neutral (idling)
If this position is selected, the gearbox is in neutral. Power is not transmit-
ted to the wheels and the engine does not have a braking function.
Never use the N position to drive down a long hill. There is no engine brak-
ing and the brakes are subjected to excessive stain.
You could damage the automatic gearbox if you drive down hills with the
gearbox lever in position N and the engine switched off.
D - Drive (forward)
In this position the gearbox automatically changes to a lower or higher gear,
according to the engine's requirements, the driving style and speed. The
braking effect of the engine when driving downhill is very limited when the
selector is in this position. The instrument panel display shows the selected
gear as well as the selector lever in position D.
If position N has been selected and you wish to select D, you must press the
foot brake if the vehicle is stationary, or travelling at under 5 km/h (3 mph).
S - Standard driving position (Sport programme)
When the selector lever is in position S, it will automatically change up into
a higher gear later, and change down into a low gear, if compared with posi-
tion D. This way, it is possible to take full advantage of the engine reserve
power, depending on the engine demand, driving style and speed. The
braking effect of the engine when driving downhill is very limited. On the
instrument panel display the selected gear is shown as well as the selector
lever to position S.
To select gear range S, press the lock button on the selector lever.

Driving
WARNING
If the vehicle moves with no control, an accident and serious injury may
occur.
● As a driver, you should never leave your vehicle if the engine is run-
ning and a gear range is engaged. If you have to leave your vehicle while
the engine is running, you must always apply the handbrake and engage
the parking lock position P.
● With the engine running and D or R engaged, you must hold the vehi-
cle stopped by pressing the brake pedal. Even while idling, the power
transmission is not fully interrupted and the vehicle could keep moving
forward.
● Never accelerate when moving the selector lever or you may cause an
accident.
● Never move the selector lever to “R” or “P” when driving. Risk of acci-
dent.
● Before driving down a very steep slope, reduce your speed and shift
to first gear.
● Always hold the vehicle on the foot brake if you stop on hills. Other-
wise, the vehicle could roll back.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat
and will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.
WARNING
Never switch the engine off until the vehicle is stationary. You could lose
control of your vehicle. This could cause an accident and serious injury.
● The airbags and belt tensioners do not work when the ignition is
switched off.
WARNING (Continued)
● The brake servo does not work with the engine off. You need more
force to stop the vehicle.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Never remove the key from the ignition if the vehicle is in motion. The
steering lock could suddenly engage, and you would not be able to steer
the vehicle.
● Never allow the vehicle to roll downhill with the selector lever in “N”,
regardless of whether the engine is running or not.
CAUTION
If you allow the vehicle to move when the engine is switched off or with the
selector lever in position “N”, take your foot off the accelerator and wait un-
til the engine starts idling before returning to position “D”.
Gear-change indicator
The recommended gear for saving fuel is indicated on the dash screen of
certain vehicles during driving.

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.
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 175
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 71.
At speeds of up to approximately 80 km/h (50 mph), it is able to balance
out differences 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 other driven wheel via the differential.
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed that the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled
down.

WARNING (Continued)
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static charge. Never short the battery terminals. High-energy sparks can
cause injury.
● A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
● Keep children away from acid and batteries.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only
switch off the light.
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
● When disconnecting the battery from the vehicle on-board network,
disconnect first the negative cable and then the positive cable.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can also freeze at temperatures close to 0 °C
(+32 °F).
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
● For vehicles with the battery in the luggage compartment: Check that
the battery gas ventilation hose is securely attached.CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Do not expose the battery to direct sunlight over a long period of time,
as the intense ultraviolet radiation can damage the battery housing.
● If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries. – Open the engine bonnet and the battery cover ⇒
in Safety in-
structions on working in the engine compartment on page 207
⇒
in Warnings on handling the battery on page 220. For vehi-
cles with the battery under the spare wheel, open the rear lid
and lift the floor covering. The battery is located next to the
spare wheel.
– Check the colour display in the "magic eye" on the top of the
battery.
– If there are air bubbles in the window, tap the window gently
until they disperse.
The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒ page 267. The location of the battery in the luggage com-
partment can be seen in ⇒ Fig. 195.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.

Tyre useful life
The useful life of tyres is dependent on tyre pressure, driving
style and fitting.
Fig. 145 Tyre tread wear
indicators
Fig. 146 Diagram for
changing wheels Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 145, 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 223.
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. 146. 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.

Vehicle Tools
The vehicle tools are located under the floor panel in the
luggage compartment. – Lift luggage compartment floor panel.
– Take the vehicle tools out of the vehicle.
The vehicle tool kit includes:
● Jack*
● Hook to remove integral* trim and screw caps.
● Box spanner for wheel bolts*
● Towline anchorage*
● Adapter for the anti-theft wheel bolts*
Some of the items listed are only provided in certain model versions, or are
optional extras.
WARNING
● The factory-supplied jack is only designed for changing wheels on
this model. On no account attempt to use it for lifting heavier vehicles or
other loads. Risk of injury.
● Use the jack only on a firm, level ground.
WARNING (Continued)
● Never start the engine when the vehicle is on the jack. Risk of acci-
dent.
● If work is to be carried out underneath the vehicle, this must be se-
cured by suitable means. Otherwise, there is a risk of injury.
Spare wheel (temporary spare wheel)*
The spare wheel (temporary spare wheel) must only be used
for the minimum necessary time.
The temporary spare wheel is stored under the floor panel in the luggage
compartment and is attached by a thumbnut.
How to use the temporary spare wheel
If you ever have a punctured tyre or loss of pressure, the temporary spare
wheel is only intended for temporary use until you reach a workshop.
Change it for a duty wheel as soon as possible.
Please note the following restrictions when using the temporary spare
wheel. This temporary spare wheel has been specially designed for your ve-
hicle, thus, it cannot be changed with the temporary spare wheel from an-
other 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 tem-
porary spare wheel.
Safety FirstOperating instructionsPractical TipsTechnical Specifications
230If and when
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare wheel 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 possi-
ble after fitting the temporary spare wheel.
● Do not drive faster than 80 km/h (50 mph), since higher speeds can
cause an accident.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
● Never use more than one temporary spare wheel 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.
Tyre repair kit*
The tyre repair kit (for vehicles not including a temporary
spare wheel) is stored under the floor panel in the luggage
compartment. In the event of a punctured tyre, your vehicle is equipped with the Tyre Mo-
bility System (tyre repair kit).
The tyre repair kit consists of a container with sealing product 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 pene-
tration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product.
Wheel change Preparation 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 vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch the engine off. Switch the hazard warning lights on and
place the warning triangles in position.
– 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.
231
If and when
WARNING
Switch on the hazard warning lights and place the warning triangles in
position. This is for your own safety and also warns other road users.
CAUTION
If you have to change the wheel on a slope, it is essential to lock the parallel
wheel on the same axle as that to be changed, with a wedge or similar in
order to immobilise the vehicle.
Note
Please observe legal requirements when doing so.
Changing a wheel
Change the wheel as described below
– Remove the hub caps or the integral trim .
– Slacken the wheel bolts .
– Raise the vehicle with the jack at the corresponding point.
– Remove the wheel and then fit the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner.
– Replace the hub cap. After changing a wheel
After changing the wheel there are still tasks to complete.
– Put the tools and jack back in the luggage compartment.
– Place the wheel with the defective tyre in the luggage compart-
ment and secure it.
– Check the tyre pressure of the newly fitted tyre as soon as pos-
sible.
– Have the tightening torque of the wheel bolts checked as soon
as possible with a torque wrench. The prescribed torque must
be 120 Nm.
Note
● If you notice that the wheel bolts are corroded and difficult to turn when
changing a wheel, they must be replaced before having the wheel bolt tight-
ening torque checked.
● For safety reasons, drive at moderate speeds until the wheel bolt tight-
ening torque has been checked.
