● 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
gear 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 displays 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.
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
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 is engaged. If you have to leave your vehicle while the
engine is running, you must always apply the handbrake and engage
parking lock P.
● If the engine is running and if D or R are engaged, you will need to
hold the vehicle stopped by depressing footbrake down. The car would
creep forward as the power transmission is not fully interrupted even
when the engine is idling.
● Never accelerate when moving the selector gear 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.

Driving
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 car to roll downhill with the selector lever in “N”, re-
gardless of 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”.
Kickdown 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 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
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
160Driving
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 you 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 turns off when the handbrake 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 it is only partially released, this will cause rear brakes overheating,
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 car 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.

Driving
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 occupants.
● Never leave children alone in the vehicle. They could set the vehicle
in motion, for example, by releasing the handbrake or the gear 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 ESP. 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.
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.
Note
The Official Service or a specialist workshop can tell you if your vehicle is
equipped with this system.
Acoustic parking aid system* Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.
Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors loca-
ted on the rear bumper. The measuring range of the sensors starts approxi-
mately and depending on the nature of the obstacle at a distance of:
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m

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 Hydraulic Brake Assist function (HBA) is only included in
vehicles with ESP.
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.

WARNING
● The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slip-
pery or wet. The increased accident risk cannot be reduced by the brake
assist system.
● The brake assist system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with the brake assist system! There-
fore, it is essential that you adjust your speed to suit the road and traffic
conditions. Do not let the extra safety features tempt you into taking any
risks when driving.
Anti-lock brake system and traction control
ABS Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking dur-
ing braking.
The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for this wheel.
The driver is made aware of this control process by a pulsating of the brake
pedal and audible noise. This is a deliberate warning to the driver that one
or more of the wheels is tending to lock and the ABS control function has
intervened. In this situation it is important to keep the brake pedal fully de-
pressed so the ABS can regulate the brake application. Do not “pump”. If you brake hard on a slippery road surface, the best possible control is re-
tained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in
all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
● The anti-lock brake system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS is
working (to counteract locked wheels under braking), you should reduce
speed immediately to suit the road and traffic conditions. Do not let the
extra safety features tempt you into taking any risks when driving.
● The effectiveness of ABS is also determined by the tyres fitted
⇒ page 215.
● If the running gear or brakes are modified, the effectiveness of the
ABS could be severely limited.
Traction control system (TCS)*
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating. The system al-
ways includes ABS
Description and operation of the traction control system during
acceleration (TCS)
TCS reduces engine power to help prevent the drive wheels of front-wheel
drive vehicles losing traction during acceleration. The system works in the
entire speed range in conjunction with ABS. If a malfunction occurs in the
ABS, the TCS will also be inoperative.
169
Intelligent technology
TCS 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 TCS is switched on automatically when the engine is started. If necessa-
ry, it may be turned on or off by briefly pushing the ESP button on the centre
console.
When the TCS is off, the warning lamp is lit. The TCS should normally be
left on. Only in exceptional circumstances, when the slipping of the wheels
is required, can they be disconnected using the ESP button, for example.
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on loose surfaces
● When the vehicle is bogged-down, to free it by rocking.
The TCS should be switched on again as soon as possible.
WARNING
● It must be remembered that TCS cannot 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. 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 fit-
ted 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, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS and TCS. XDS*
Driveshaft differential
When taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in under-
steer or “lengthening” of the trajectory.
By using the ESP sensors and signals, the XDS system is able to detect and
correct this effect.
Through the ESP, the XDS brakes the inner wheel, thereby counteracting the
excess drive torque in this wheel. This means that the driver's desired tra-
jectory is much more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.
Electronic Stability Programme (ESP)* General notes
The Electronic Stability Programme increases the vehicle's
stability on the road.
The Electronic Stability Programme helps reduce the danger of skidding.
The Electronic Stability Programme (ESP) consists of ABS, EDL and TCS.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
170Intelligent technology
Electronic Stability Programme (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 vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates 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.
WARNING
● It must be remembered that ESP cannot 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. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
CAUTION
● In order to ensure that ESP functions 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, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS, EDL, ESP and TCS. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 168.
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 drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 69.
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.
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.
