Brake assist systems


Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
Antilock Braking System (ABS)
Traction Control System (TCS)
Electronic Differential Lock (EDL)
WARNING
A lack of fuel can cause irregular engine running or cause the engine to shut
■
down. The brake assist systems would then fail to function – risk of accident!
Adjust the speed and driving style to the current visibility, weather, road and
■
traffic conditions. The increased safety provided by the brake assist systems
must not tempt you to take safety risks – risk of accident!
In the event of an ABS fault, visit a specialist garage immediately. Adjust
■
your style of driving according to the damage to the ABS, as you will not know
the exact extent of the damage or the extent to which this is limiting the
braking efficiency.
CAUTION
All four wheels must be fitted with the same tyres approved by the manufactur-
■
er to ensure the brake assist systems operate correctly.
Changes to the vehicle (e.g. to the engine, brakes, chassis or another combina-
■
tion of tyres and wheels) can influence the functionality of the brake assist sys-
tems » page 112, Modifications, repairs and technical alterations.
Note
If a fault occurs in the ABS system, the ESC, ASR and EDL will also fail to work. An
ABS fault is indicated with the warning light » page 17.

Electronic Stability Control (ESC)

First read and observe the introductory information and safety warn-
ings on page 77.
The ESC system helps improve control of the vehicle in situations where it is be-
ing operated at its dynamic limits, such as a sudden change to the direction of
travel. The risk of skidding is reduced and your car thus offers greater driving sta-
bility depending on the conditions of the road surface.
The ESC system is automatically activated each time the ignition is switched on.
77
78
The direction which the driver wishes to take is determined based on the steering
78
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. In the event of deviations, such as the car beginning to
78
skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light
ment cluster.
The following systems are integrated into the electronic stabilisation control
(ESC):
›
Antilock brake system (ABS),
›
Traction control (TCS);
›
Electronic Differential Lock (EDL)
›
Hydraulic Brake Assist (HBA)
›
Hill Hold Control (HHC).
In the event of an ESC fault, the ESC warning light
ment cluster » page 16.
Hydraulic Brake Assist (HBA)
The HBA is activated by very quick operation of the brake pedal. HBA increases
the braking effect and helps to shorten the braking distance. In order to achieve
the shortest possible braking distance, the brake pedal must be applied firmly un-
til the vehicle has come to a standstill.
The ABS is activated faster and more effectively with the intervention of the HBA.
The HBA function is automatically switched off when the brake pedal is released.
Hill Hold Control (HHC)
When driving on slopes, HHC allows you to move your foot from the brake pedal

to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake
pedal for approx. 2 seconds after the brake pedal is released.
