Intelligent Technology

Operating principle

Electronic stability programme (ESP)*

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.

General

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 vehicle 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.

Fig. 191 ESP switch

General

During an intervention of the system, the warning light  flashes quickly in the

instrument cluster ⇒ page 38.

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 vehicle thus offers greater driving stability depending on the conditions of

the road surface. This occurs at all speeds.

The ESP operates in combination with the ABS ⇒ page 181, “Antilock brake system

(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.

The ESP warning light lights up in the instrument cluster when there is a fault on the

ESP  ⇒ page 38.

The following systems are integrated into the electronic stability programme:

•

Electronic Differential Lock (EDL),

Traction control system (TCS),

Active driver-steering recommendation (DSR),

Antilock brake system (ABS),

Brake Assist,

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

braked. The vehicle can continue to be driven and has the same characteristics as a

vehicle not fitted with EDL.

WARNING (continued)

increased safety offered must not tempt you to take greater risks than other-

wise - risk of an accident!

The EDL switches on again automatically as soon as the brake has cooled down.

EDL Off-road*

After switching on the Off-road mode ⇒ page 185, EDL Off-road is activated.

Note

EDL Off-road is matched in such a way that it assists the traction of the vehicle when

driving on an unfirm ground.

•

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.

EDL is activated earlier in the Off-road mode than in the normal mode. The brake

pressure builts up more quickly on the slipping wheel, on one axle, as well as diag-

onally.

•

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-

nation of tyres and wheels) can influence the function of the ESP ⇒ page 238,

“Accessories, changes and replacement of parts”.

WARNING

Electronic Differential Lock (EDL)*

•

Carefully depress the accelerator 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!

The electronic differential lock prevents an individual wheel from

slipping.

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!

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.

Note

Operating principle

•

If the ABS or ESP warning light comes on, this may also indicate a fault in the

EDL. Please have the vehicle inspected as soon as possible by a specialist garage.

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.

•

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-

nation of tyres and wheels) can influence the function of the EDL ⇒ page 238,

“Accessories, changes and replacement of parts”.

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

ESP*, you can switch off the TCS with the aid of the button ⇒ page 177, fig. 191. The

TCS warning light  lights up in the instrument cluster ⇒ page 38 if the system is

switched off.

Traction control system (TCS)

The traction control system prevents the driven wheels from spinning

when accelerating.

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 vehicle when it has become stuck.

then you should switch on the TCS again.

Fig. 192 TCS switch

TCS Off-road*

After switching on the Off-road mode ⇒ page 185, TCS Off-road is activated.

General

TCS Off-road provides a more effective acceleration of the vehicle on an unfirm

ground, as it allows higher traction between the slipping wheels and the ground.

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.

The system operates at speeds of up to 30 km/h.

Operating principle

The TCS switches on automatically when the 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 are spinning, the force transmitted to the road surface is

automatically adapted by reducing the engine speed. This occurs at all speeds.

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!

The TCS operates in combination with the ABS ⇒ page 181, “Antilock brake system

(ABS)”. The TCS will not function if a fault exists in the ABS system.

The TCS warning light lights up in the instrument cluster when there is a fault on the

TCS  ⇒ page 38.

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.

During an intervention of the system, the TCS warning light  flashes in the instru-

ment cluster ⇒ page 38.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-

nation of tyres and wheels) can influence the function of the TCS ⇒ page 238,

Switching off

You can switch the TCS off and on again as you wish. On vehicles fitted with ABS,

you can switch off the TCS by pressing the button ⇒ fig. 192, on vehicles fitted with

“Accessories, changes and replacement of parts”.

Corrosion

Active driver-steering recommendation (DSR)*

Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has been

parked for a long period and if you do not make much use of the braking system.

Vehicles with ESP are equipped with active driver-steering recommendation (DSR).

We recommend cleaning the brake discs by firmly applying the brakes at a fairly

high speed if you do not make much use of the braking system or if surface corro-

sion is present ⇒

.

Faults in the brake surface

If you notice that the braking distance has suddenly become longer and that the

brake pedal can be depressed further, it is possible that a brake circuit of the dual-

circuit brake system has failed. Drive, in such cases, to the nearest specialist garage

without delay in order to have the problem rectified. Drive at a reduced speed while

on your way to the dealer and adapt your style of driving to the higher brake pedal

pressure required.

WARNING

Even with this function the vehicle cannot steer itself! The driver is further-

more responsible for the steering of the vehicle!

Brakes

Low brake fluid level

An insufficient level of brake fluid may result in problems in the brake system. The

level of the brake fluid is monitored electronically ⇒ page 40, “Brake system ”.

What has a negative effect on braking efficiency?

Wear-and-tear

Wear-and-tear to the brake pads is greatly dependent on the operating conditions

of the vehicle and your style of driving. Particularly if you drive a great deal in towns

and over short distances or if you adopt a sporty style of driving, it may be neces-

sary to have the thickness of the brake pads inspected at a specialist garage

between the service inspections.

WARNING

•

Only apply the brakes for the purpose of drying and cleaning the brake

discs if the traffic conditions permit this. Do not place any other road users

in jeopardy.

•

When retrospectively mounting a front spoiler, solid wheel hubs etc. one

must ensure that the air supply to the front wheel brakes is not reduced

otherwise the braking system could run too hot.

Wet roads or road salt

There may be a certain delay before the brakes take full effect under certain condi-

tions such as when driving through water, during heavy rain showers or after the

vehicle has been washed in an automatic vehicle wash, since the brake discs and

brake pads may be moist or even have a coating of ice on them in winter. You

should dry the brakes as soon as possible by applying and releasing the brakes

several times.

•

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 pres-

sure on the brake pedal. This guideline also applies to any new brake pads

installed at a future date.

There also may be a certain delay before the full braking efficiency is available when

driving on roads which have been treated with road salt if you have not used the

brakes for some considerable time beforehand. The layer of salt on the brake discs

and brake pads must first be rubbed off when you apply the brakes.

Intelligent Technology 181

Antilock brake system (ABS)

Caution

ABS prevents the wheels locking when braking.

•

Never allow the brakes to rub by applying slight pressure if you do not wish to

brake the vehicle. This causes the brakes to overheat and can also result in a longer

braking distance and excessive wear.

General

The ABS contributes significantly to enhancing the active safety of your vehicle.

Compared to a vehicle 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.

•

Before negotiating a steep downhill section, reduce your speed, shift down into

the next lower gear. This enables you to make full use of the braking power of the

vehicle and reduces the strain on the brakes. Any additional braking should be done

intermittently, not continuously.

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.

Note

The brake light flashes automatically in case of an emergency braking at speeds

greater than 60 km/h or with the intervention of the ABS, which lasts longer than 1.5

seconds. After the speed was reduced below 10 km/h or the vehicle was stopped,

the brake light stops flashing and the hazard warning light system switches on. The

hazard warning light system is switched off automatically after accelerating or

driving off again.

Operating principle

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!

Brake booster

The brake booster boosts the pressure which you generate with the brake pedal.

The necessary pressure is only generated when the engine is running.

ABS Off-road*

After switching on the Off-road mode ⇒ page 185, ABS Off-road is activated.

ABS Off-road increases the braking power of the vehicle on an unfirm ground, as it

keeps the wheels blocked for a longer period of time when the brake is applied

while sliding. The system is only available, if the front wheels are in the straight-

ahead position.

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.

The system operates at speeds of up to 50 km/h.

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 normal braking system is still fully functional if there is an ABS fault.

The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist

function is also not available. Further information on the ESP ⇒ page 177.

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 the

extent of the fault and in how far the braking efficiency is affected.

WARNING

•

The Brake Assist is also not able to overcome the physical limits of your

vehicle in terms of the braking distance required.

Adapt your speed to the conditions of the road surface and to the traffic

situation.

Note

•

A warning light comes on if a fault occurs in the ABS system  ⇒ page 39.

The increased safety offered by the Brake Assist must not tempt you to

take a greater safety risk than otherwise.

Brake Assist*

Uphill-Start off-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 uphill-start off-assist makes it much easier to start off on steep hills. The system

assists a start off by holding the brake pressure produced by the brake pedal actu-

ation for approx. 2 seconds after releasing the brake pedal. The driver can therefore

move his foot from the brake pedal to the accelerator pedal and start off on the

slope, without having to actuate the handbrake. The brake pressure drops gradually

the more you operate the accelerator pedal. If the vehicle does not start off within

2 seconds, it starts to roll back.

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 vehicle to achieve its maximum deceleration and the vehicle 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 vehicle. You must apply the

brake pedal firmly and hold it in this position in order to achieve the shortest

possible braking distance.

The uphill-start off-assist is active in the event of a 3 % slope, if the vehicle door is

closed. It is always active on slopes when in forward or reverse start off. When

driving downhill, it is inactive.

Electromechanical power steering

The power steering enables you to steer the vehicle with less physical force.

Intelligent Technology 183

indicates that the Downhill Drive Support is available ⇒ page 41.

Note

•

During an intervention of the Downhill Drive Support, the brake lights do not

light up.

The vehicle speed, which is maintained by the Assist System, is selected by the

driver while driving on a downhill section as of the moment the first intervention of

the Assist System is performed or else, while driving on a downhill section, the

driver must control the vehicle speed until the Assist System intervenes for the first

time. When the Assist System actively intervenes, this is indicated by the warning

light flashing or by a pulsating movement of the brake pedal, similar to the interven-

tion of the ABS.

•

Do not switch off the Off-road mode during an intervention of the Assist

System.

The Downhill Drive Support is available in the speed range of 2 km/h up to 30 km/h.

If the gear is engaged and the clutch pedal is not pressed, the lower limit of the

idling speed corresponds to the respective gear which is engaged.

You can increase or reduce the speed, even when no gear is engaged, by operating

the accelerator or brake pedal. Thus the function is always interrupted and is reac-

tivated afterwards.

The Downhill Drive Support is activated automatically if the following conditions

are met:

•

the Off-road mode is switched on and the warning light  lights up in the

instrument cluster,

the engine of the vehicle is running and either the 1st, 2nd, 3rd gear, the reverse

gear or no gear is engaged,

•

the speed is less than 30 km/h,

the downhill gradient is at least 10% (when driving over sleepers the limit can

briefly drop to 8%),

•

neither the accelerator nor the brake pedal is operated.

It is however a requirement that the vehicle has sufficient grip on the soil. The

Downhill Drive Support cannot properly fulfil its function on slushy soil due to

physical reasons (ice or mud).

The Downhill Drive Support is deactivated when braking or accelerating or if the

downhill gradient is less than 10%.
