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 hill. The engine does not function
as a brake 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.

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 kickdown features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction
and skid.
● You should use the kickdown feature only when traffic and weather
conditions allow it to be used safely.
Handbrake Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 119 Handbrake be-
tween the front seats Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
–
Pull the handbrake lever up firmly ⇒ Fig. 119.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ Fig. 119 and guide the handbrake lever
down fully ⇒
.
Always apply the handbrake as far as it will go in order to prevent yourself
from driving with the handbrake applied by mistake ⇒
.
The handbrake warning lamp lights up when the handbrake is applied
and the ignition switched on. The warning lamp turns off when the hand-
brake is released.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● If the handbrake is only partially released, this will cause the rear
brakes to overheat, which can impair the function of the brake system
and could lead to an accident. This also causes premature wear on the
rear brake pads.
CAUTION
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected.

Parking
The handbrake should always be firmly applied when the
vehicle is parked.
Always note the following points when parking the vehicle:
–Use the brake pedal to stop the vehicle.
– 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-start assist*
This function is only included in vehicles with ESC. This device helps when starting uphill.
These are the basic operation conditions: doors closed, brake pedal press-
ed down and vehicle in neutral. The system gets activated on engaging
gear.
After removing your foot from the brake pedal, the braking force is main-
tained for a few seconds to prevent the vehicle from moving backward when
putting into gear. This short space of time is enough to start the vehicle
with ease.
This system also works when reversing uphill.

Adjusting set speed*
The speed can be altered without touching the accelerator or
the brake.

trol
Setting a higher speed
– Press the upper part RES of the rocker switch ⇒ Fig. 122 B
to
increase the speed. The vehicle will continue to accelerate as
long as you keep the rocker switch pressed. When you release
the switch, the new speed is stored.
Setting a lower speed
– Press the lower part SET– of the rocker switch B
to reduce the
speed. The vehicle will automatically reduce its speed for as
long as you keep the switch pressed. When you release the
switch, the new speed is stored.
When you increase speed with the accelerator and then release the pedal,
the system will automatically restore the set speed. This will not be the
case, however, if the vehicle speed is more than 10 km/h (mph) higher than the stored speed for longer than 5 minutes. The speed will have to be stor-
ed again.
Cruise control is switched off if you reduce speed by depressing the brake
pedal. Reactivate the control by pressing once on the upper part of the rock-
er switch RES+ ⇒ Fig. 122

Intelligent technology
Brakes Brake servo
The brake servo increases the pressure you apply to the brake pedal. It
works only when the engine is running .
If the brake servo is not functioning due to a malfunction, or if the vehicle
has to be towed, you will have to press the brake pedal considerably harder
to make up for the lack of servo assistance.
WARNING
The braking distance can also be affected by external factors.
● Never let the vehicle coast with the engine switched off. Failure to do
so could result in an accident. The braking distance is increased consid-
erably when the brake servo is not active.
● If the brake servo is not working, for example when the vehicle is be-
ing towed, you will have to press the brake pedal considerably harder
than normal.
Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is only included in
vehicles with ESC.
In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances.
This is when the brake assist system comes into action. When pressing the
brake pedal rapidly, the assistant interprets it as an emergency. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the brake pedal. The brake assist system
switches off automatically as soon as you release the brake.
Automatic hazard warning lights activation
The brake lights flash automatically to indicate that the vehicle is braking
suddenly or in an emergency situation. If the emergency braking continues
until the vehicle comes to a standstill, the hazard warning lights will then
come on and the brake lights will remain on permanently from that moment.
The warning lights will automatically switch off when the vehicle begins to
move again or when the "warning" light button is pressed.
171
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 169.
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.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
174Driving and the environment
recommend that you have the thickness of your brake pads checked by a
Technical Service more frequently than recommended in the Maintenance
Programme.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case
the brakes should be dried by pressing the brake pedal several times.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.
● New brake pads must be run in and do not have the correct friction
during the first 200 km (120 miles). However, the reduced braking ca-
pacity may be compensated by pressing on the brake pedal a little hard-
er. This also applies when the brake pads have to be changed further on.
● If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal.
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
WARNING (Continued)
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 190, Technical modifi-
cations.
● If a brake system circuit fails, the braking distance will be increased
considerably. Contact a specialised workshop immediately and avoid un-
necessary journeys.
Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine
oil ⇒ page 206, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 248.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 65. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
