Handbrake
Applying the handbrake
– Pull the handbrake lever up fully.
Releasing the handbrake
– Pull the handbrake lever up slightly and at the same time press in the
locking button ⇒fig. 103.
– Hold the button pressed and push the handbrake lever down fully
⇒ .
The handbrake warning light lights up when the handbrake is applied, provided the ignition is on.
A warning signal sounds and the following te xt 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 6 km/h for more than 3 seconds.
WARNING
•Please note that the handbrake must 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 the 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 (manua l 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 distance between the rear bumper and an obstacle located behind the vehicle with th e aid of ultrasound sensors. The sensors are integrated in the rear bumper.

Starting-off and Driving94
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area ⇒page 93, fig. 104). The interval between the warning signals becomes shorter as the clearance is reduced.
A continuous tone sounds fr om a clearance of just 30 cm (Bereich ) - danger area. You should not reverse any further after this signal sounds!
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 parking the vehicle or carrying ou t similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that there is no small obstacle, such as a rock, thin post, trailer drawbar etc., behind your vehicle. Such an obstacle might not be within the range detected by the sensors.
Note
•When operating with a trailer, the parking aid is without function.
•A system fault is indicated if a warning signal sounds for about 5 seconds after switching the ignition on and engaging reve rse gear and there is no obstacle close to your vehicle. Have the fault re ctified by a specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking aid to operate properly.
•If the parking aid is activated and the selector lever of the automatic gearbox is in the position , warning signal indicates interruption (vehicle can no longer move).
Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than 30 km/h, once it has been set, without you having to depress the 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 syst em makes it possible - particularly 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 or R.

Intelligent Technology
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 149, “Antilock brake system (ABS)*”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light ⇒page 27 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. 145. The ESP warning light ⇒page 27 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 in certain exceptional cases, such as when you wish to have wheel slip, to switch off the system.
Examples:

Intelligent Technology146
•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 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 193, “Accessories, changes and replacement of parts”.
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 149, “Antilock brake system (ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 26 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. 146. The TCS warning light ⇒page 26 lights up in the instrument cluster when the TCS is switched off.

Electronic Differential Lock (EDL)*
The electronic differential lock pr events an individual wheel from
slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
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 slippery 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 or TCS or ESP warning light comes on, this may also indicate a fault in the EDL. Please have the car inspected 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 193, “Accessories, changes and replacement of parts”.
