Starting-off and Driving
104
A warning signal sounds and the following text appears in the display* if you have
inadvertently driven off with the handbrake applied:
"Handbrake on"
The handbrake warning is activated if you drive at a speed of more than 5 km/h for
more than 3 seconds.
WARNING
•Please note that the handbrake mu st be fully released. A handbrake
which is only partially released can re sult in the rear brakes overheating
which will have a negative effect on th e operation of the brake system - risk
of accident! In addition this can result in premature wear of the rear brake
pads.
•Never leave children unattended in th e vehicle. The children might, for
example, release the handbrake or take the vehicle out of gear. The vehicle
might then move off - risk of accident!
Caution
After the car has come to a stop, always firs t of all apply the handbrake firmly before
then additionally engaging a gear (manual gearbox) or moving the selector lever
into position P (automatic gearbox).
Parking aid*
The parking aid provides a warning of obstacles behind the vehicle.
The audible parking aid determines the di stance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The sensors
are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area ⇒ fig. 118 ). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a clearanc e of just 30 cm (Bereich ) - danger
area. From this moment on do not continue driving in the selected direction or
the direction from where the obstacle is reported!
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confir med by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.

WARNING
•The parking aid is not a substitute fo r the driver paying proper attention
and it is always the driver's responsibility to take care when reversing the
vehicle or carrying out similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., in front or
behind your vehicle. Such an obstacle might not be within the range
detected by the sensors.
Note
•Only the front parking aid operates if yo u are towing a trailer (applies only to
models which feature a factor y-fitted towing device*).
•If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, th is indicates a system fault. The fault is
confirmed additionally when the symbol
 flashes in the button ⇒page 105,
fig. 119 . Have the fault rectified by a specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than 30 km/h (20
mph), once it has been set, without you having to depress th e accelerator pedal.
This is only possible within the range which is permitted by the power output and
braking power of the engine. The cruise control system makes it possible - particu-
larly on long journeys - for you to rest your “accelerator foot”.
WARNING
•The cruise control system must not, for safety reasons, be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads or
loose chippings) - risk of accident!
•In order to prevent unintentional use of the cruise control system, always
switch off the system after use.
Note
•Models fitted with a manual gearbox: Always depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral. Otherwise the
engine can rev up unintentionally.
•The cruise control system is not able to maintain a constant speed when driving
on steep downhill sections. The weight of the vehicle increases the speed at which
it travels. One should shift down in good time to a lower gear or slow the vehicle
down by applying the foot brake.
•It is not possible on vehicl es fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N , R or 2.
Storing a speed
– Move the slide switch ⇒fig. 121 into the ON position.

Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in borderline driving
situations such as when negotiating a curve too fast. The risk of skidding is reduced
and your car thus offers greater driving stability depending on the conditions of the
road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability programme:
•Electronic Differential Lock (EDL),
•Traction control system (TCS),
•Antilock brake system ABS,
•Brake Assist. Operating principle
The ESP switches on automatically when the engine is started and then conducts a
self-test. The ESP control unit processes data from the individual systems. It also
processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin g pressure and the steering angle.
The direction which the driver wishes to ta ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. If differences exis t, such as the car beginning to skid, the
ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is braked.
Intervention into the brake system takes place primarily on the outer front wheel of
a vehicle which tends to oversteer (tendency for the rear of the vehicle to break
away) while occurs this is on the inner re ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied
by noises.
The ESP operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light ⇒page 28 lights up in the instrument cluster when there is a
fault on the ESP.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button
⇒ fig. 163 . The ESP warning light ⇒page 28 lights up in the instrument cluster
when the ESP is switched off.
The ESP should normally always be switched on. It may be good practice to switch
the system off only in particular exceptional situations if you desire wheel slip.
Examples:
•when driving with snow chains,

•when driving in deep snow or on a loose surface,
•when it is necessary to rock a ca r free when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the
vehicle. Even if a vehicle fitted with ESP you should still always adapt your
style of driving to the condition of the road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The
increased safety offered must not tempt you to take greater risks than other-
wise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling circumferences of the tyres can lead to an
undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can influence the function of the ESP ⇒page 205.
Traction control system (TCS)*
The traction control system prevents the driven wheels from spinning
when accelerating.
General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when th e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the
ABS sensors. If the wheels ar e spinning, the force transmitted to the road surface is
automatically adapted by reducing the engi ne speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 28 lights up in the instrument cluster when there is a
fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒ fig. 164 . The TCS warning light ⇒page 28 lights up in the instrument cluster
when the TCS is switched off.

The TCS should normally always be switched
on. It may be good practice to switch
the system off only in particular exceptional situations if you desire wheel slip.
Examples:
•when driving with snow chains,
•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
The EDL ⇒page 157, “Electronic Differential Lock (EDL)” is a part of the TCS. THE
EDL operates independently of the TCS (a lso when the TCS has been switched off
using the TCS button).
WARNING
You should always adjust your style of driving to the conditions of the road
surface and the traffic situation. The increased safety offered must not tempt
you to take greater risks than otherwise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the TCS. Differing rollin g circumferences of the tyres can lead to
an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can influence the function of the TCS ⇒page 205,
“Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)
The electronic differential lock pr events an individual wheel from
slipping.
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditio ns of the road surface are unfavourable. Operating principle
The EDL is activated automatically, that is without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors.
Should only
one drive wheel begin spinning on a sl ippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes
the slipping wheel and the differential transmits a greater driving force to the other
driven wheel. This control proce ss is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unus ually severe stresses exist in order to
avoid excessive heat generation in the disc brake on the wheel which is being
braked. The vehicle can continue to be driven and has the same characteristics as a
vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•Depress the accelerator carefully when accelerating on uniformly slip-
pery road surfaces, such as ice and sn ow. The driven wheels might still spin
despite the EDL and affect the stability of the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition of road
surface and to the traffic situation even when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than
otherwise - risk of an accident!
Note
•If the ABS warning light comes on, this may also indicate a fault in the EDL.
Please have the car inspec ted as soon as possible by a specialist garage.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can in fluence the function of the EDL ⇒page 205,
“Accessories, changes and replacement of parts”.
