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 vehicle about its vertical axis, the lateral accel-eration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take 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 exist, 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 rear 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 155, “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. 158. 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:

The TCS 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:
•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.
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 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 TCS ⇒page 200, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents 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 conditions 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 process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually 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 snow. 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 influence the function of the EDL ⇒page 200, “Accessories, changes and replacement of parts”.

WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running. Greater physical effort for braking is required when engine is switched off. Because if you do not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)*
ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle. Compared to a car not fitted with the ABS brake system, you are able to retain optimal steering ability even during a full brake application on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all circumstances as a result of the ABS. The braking distance for example on gravel and fresh snow, when you should anyway be driving slowly and cautiously, will be longer.
Operating principle
As soon as the vehicle speed has increased to about 20 km/hour an automatic test procedure is conducted during which you will be able to hear a pumping noise for about 1 second.
The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tending to lock. This control cycle is notice-able from a pulsating movement of the brake pedal which is accompanied by noises. This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optimally control the brake application in this braking range. Never interrupt the application of the brakes!
WARNING
•The ABS can also not overcome the physical limits of your vehicle. Please do not forget this, particularly when driving on icy or wet road surfaces. If the ABS is operating within the control range, adapt your speed immediately to the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!
•The normal braking system is still fully functional if there is an ABS fault. Visit a specialist garage as quickly as possible and adjust your style of driving to take account of the ABS fault in the meantime since you will not know how great the damage is.
Note
•A warning light comes on if a fault occurs in the ABS system ⇒page 27.
•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 ABS ⇒page 200, “Accessories, changes and replacement of parts”.
Brake Assist*
During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but do not depress the brake pedal with sufficient pressure. Consequently, it is not possible for the car to achieve its maximum deceleration and the car covers a greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure exists than during a normal brake applica-tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of the car. You must apply the brake

•the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving uphill or downhill),
•the vehicle is operated in unfavourable winter conditions or on an unfirm ground,
•snow chains or emergency wheel are mounted,
•the driver has a sporty style of driving (with sharp acceleration and high speed when cornering).
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several wheels, a basic setting of the system must be carried out as follows.
•Inflate all tyres to the specified inflation pressure ⇒page 194.
•Switch on the ignition.
•Press button ⇒page 156, fig. 160 for more than 2 seconds. While pressing the button, the warning light lights up. At the same time the basic values are stored, which is confirmed with an acoustic sound and then the warning light goes out.
•If the warning light does not go out after the basic setting, there is a fault in the system. Have the vehicle inspected by your nearest specialist garage.
Function description
After the basic setting of the system the “adaptation” of the tyre inflation pressures and then the tyre pressure control in the individual tyres are performed.
Warning light lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated in compar-ison to the stored basic value, the warning light ⇒ lights up. Inflate all tyres to the specified inflation pressure ⇒page 194, “Tyre life” and then perform a basic setting of the system.
WARNING
•When the warning light lights up, immediately reduce the speed and avoid sudden steering and brake manoeuvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their inflation pressures.
•The driver is responsible for the correct tyre inflation pressures. For this reason, the tyre inflation pressures must be checked regularly.
•Under certain circumstances (e.g. sporty style of driving, wintry or unpaved roads) the warning light can be delayed or does not light up at all.
•The tyre inflation pressure-control system does not take away the responsability from the driver for the correct tyre inflation pressure.
Note
The tyre inflation pressure-control system:
•does not replace the regular tyre inflation pressure control, because the system cannot detect an even pressure loss,
•cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of sudden tyre damage. In this case carefully bring the vehicle to a standstill without sudden steering movements and without sharp braking.

Driving and the Environment
The first 1 500 kilometres and then afterwards
A new engine
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear in use,
that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the full
speed of the gear engaged, that is up to the maximum permissible
engine revolutions.
During the first operating hours the engine has higher internal friction than later until all of the moving parts have harmonized. The driving style which you adopt during the first approx.1 500 kilometres plays a decisive part in the success of running in your car.
You should not drive at unnecessarily high engine revolutions even after the running-in period is complete. The maximum permissible engine speed is marked by the beginning of the red zone on the scale of the revolutions counter. Shift up into the next higher gear on a vehicle fitted with manual gearbox before the red zone is reached. During acceleration (depressing the accelerator) exceptionally high engine speeds are automatically reduced, yet the engine is not protected against too high engine speeds which are caused by incorrectly shifting down the gears resulting in a sudden increase of the engine speeds above the permitted maximum revolutions which can lead to engine damage.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do not drive at engine revolutions which are too low. Shift down as soon as the engine is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is at its normal operating temperature. Never rev up an engine which is cold, neither when the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear as early as possible are ways to minimise fuel consumption, operating noise levels as well as protects the environment and contributes to a longer life and reliability of the engine.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. You should take account of this fact for the first 500 kilometres and drive particularly carefully.
New brake pads
Allow for the fact that new brake pads do not achieve their full braking efficiency until approximately 200 kilometres. New brake pads must be first “run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced braking force by increasing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in period, you should avoid excessive stresses on the brakes. This includes, for example, violent braking, particularly from very high speeds, and also when crossing mountain passes.

The fuel consumption can naturally also be influenced by factors which are beyond the driver's control. It is, for example, normal for the fuel consumption to increase in winter and under worsened conditions such as poor road conditions, towing a trailer, etc.
The technical requirements for low fuel usage and economic efficiency of the vehicle have already been built into the vehicle at the works. Special attention has been given to minimising negative effects on the environment. It is necessary to take note of the guidelines given in this chapter in order to make best use of these characteristics and to maintain their effectiveness.
Looking ahead when driving
A vehicle's highest fuel consumption occurs it accelerates.
Avoid accelerating and braking unnecessarily. If you drive with forsight you will not need to brake so often and will also then not have to accelerate so much. Let your vehicle coast to a stop, for example, if this is possible, when you see that the next set of traffic lights is at red.
Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good fuel economy is to shift up early. You will consume more fuel if you drive at unnecessarily high revolutions in any given gear.
The ⇒fig. 162 shows the ratio of fuel consumption to the speed of your vehicle in the relevant gears. Fuel consumption in 1st gear is the highest and in 5th gear is the lowest.
Note
•The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption and resonance of the vehicle.
•Also use the information supplied by the multi-functional indicator* ⇒page 13.
Avoiding full throttle
Driving more slowly means saving fuel.
