Technical Data
The Electronic Stabilisation Program (ESP) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works
together with the ABS. If a fault in the ABS occurs, both warning lamps light
up, but if the ESP fails, only the ESP warning lamp lights up.
The ESP is started automatically when the engine is started.
The ESP switch deactivates both TCS and ESP functions. The ESP, in spite of
being deactivated, will always self-connect when necessary if brakes are
being used.
The TCS can be deactivated when in cases where wheel sliding is desirable.
For example:
•When driving with snow chains,•when driving in deep snow or on loose surfaces,•when rocking the vehicle backwards and forwards to free it from mud, for
example.
Next, the button should be pressed to reactivate the TCS.
When does the warning light switch on or flash ?•On switching the ignition on, it lights up for about two seconds to carry
out a function control.•The warning lamp will start flashing when the vehicle is moving if the ESP
or the TCS is activated.•It will light up continuously if there is a malfunction in the ESP.WARNING
•The electronic stabilisation programme (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, this can cause accidents.
•Please refer to the corresponding warning notes on ESP in ⇒page 183,
“Intelligent technology”.
Ignition lockIgnition key positions
The ignition key is used to start and stop the engine.Position
The ignition key is inserted in this position. To engage the steering wheel
lock , take out the key and turn the wheel until you hear the pin engage. You
should always engage the steering lock when you leave the vehicle. This will
help to deter thefts ⇒.

Practical tipsIntelligent technologyElectronic stabilisation programme (ESP)General notes
The electronic stabilisation programme increases the
vehicle's stability on the road.The ESP is designed to increase the degree of control in situations where the
car approaches the limits of adhesion, especially when accelerating and
cornering. It reduces the risk of skidding and improves stability in all road
conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (TCS) are all integrated into the electronic stabili-
sation programme.
How it works
The ESP control unit processes data from the three integrated systems. It also
processes additional inputs provided by other high-precision sensors. These
register the vehicle's rotation about the vertical axis (yaw rate), lateral accel-
eration, brake pressure and steering wheel angle.
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 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 car back to a stable condi-
tion. If the vehicle
over swerves (tendency of the rear to leave the road), the
brakes will act on the front wheel facing the outside of the bend. If the vehicle
under swerves (tendency to leave the bend), the braking force is applied to
the rear wheel facing the inside of the bend.
The ESP works in conjunction with the ABS ⇒page 184. If a malfunction
should occur in the ABS, the ESP will also be out of action.
Disabling
The ESP is enabled automatically when the engine is started and performs a
self-test routine.

Technical Data
the brake assist system automatically boosts the braking force to the
maximum level, up to the point where the anti-lock brake function (ABS) inter-
venes to stop the wheels from locking. You should then keep the brake pedal
pressed until the vehicle has braked to the required speed. The brake assist
system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS or the ESP.
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system. Risk of accident.Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning.General notes
The electronic differential lock (EDL) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be diffi-
cult or even impossible.
How it works
The EDL works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors, the system monitors the rotational speed of the
driven wheels ⇒
page 184. If a considerable difference in revs is detected
(approx. 100 rpm) in the speed of the driven wheels, e.g. when only one part
of the surface supporting the wheels is slippery, the system applies the brake
to slow down the skidding wheel so that more of the power is directed to the other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noises while it is working.
Moving away from a standstill
If one wheel has less grip and starts spinning (for instance, if one of the
driven wheels is on ice), keep pressing the accelerator gradually until the car
starts moving.
Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. In this case, the vehicle will
continue to run and will have the same running properties as those of another
without EDL.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•When accelerating on a uniformly slippery surface (for instance all four
wheels on ice or snow), press the accelerator gradually and carefully.
Despite EDL, the driven wheels may otherwise start to spin. This could
impair the car's stability. Risk of accident.•Even with EDL, you should always adjust your speed to suit the condi-
tions. Do not let the extra safety features tempt you into taking any risks
when driving. Failure to do so could result in an accident.Note
If the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Please take the vehicle to a specialist garage as soon as possible.

Intelligent technology
186Traction control system (TCS)
The traction control system prevents the drive wheels from
spinning when the car is accelerating.General notes
The traction control system (TCS) is one of the functions incorporated in the
electronic stabilisation programme (ESP).
The traction control system (TCS) helps the car to start moving, accelerate or
climb a gradient in slippery conditions where this may otherwise be difficult
or even impossible.
How it works
The TCS acts automatically, i.e. without the driver's intervention. With the aid
of the ABS sensors ⇒page 184, the TCS monitors the speed of the driven
wheels. If the wheels start to spin, the engine power is reduced automatically
to match the amount of grip available. The system is active across the entire
speed range.
The TCS works in conjunction with the ABS. If a malfunction occurs in the ABS,
the TCS will also be inoperative.
Note
To ensure that the TCS works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an undesired
reduction in engine power. Also see ⇒page 241.
BrakesGeneral notesNew brake pads
New brake pads do not provide optimal performance during the first 200 km
they must be “run in”. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. Avoid over-
loading the brakes during run-in.
Wear
T h e r a t e o f we a r o n t h e brake pads depends a great deal on how you drive and
the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads; road salt
In certain conditions, such as in heavy rain, or after washing the car or driving
through water, the full braking effect can be delayed by moisture (or in winter
by ice) on the discs and brake pads. The brakes should be “dried” by pressing
the pedal to restore full braking effect.
When the velocity is over 80 km/h windscreen wipers are on, the brake
system moves the pads towards the brake discs for a few seconds. This
occurs - without warning to the driver - at regular intervals and requires a
more rapid response from the brakes when driving on wet roads.
The effectiveness of the brakes can also be temporarily reduced if the car is
driven for some distance without using the brakes when there is a lot of salt
on the road in winter. In this case, the layer of salt on the brake discs and pads
has to wear off before braking.
