Brake assist systems

Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
Antilock Braking System (ABS)
Traction Control System (ASR)
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) can influence the
■
functionality of the brake assist systems
technical alterations.
If a fault occurs in the ABS system, the ESC, TCS and EDL will also fail to work.

An ABS fault is indicated with the warning light

Electronic Stability Control (ESC)

First read and observe the introductory information and safety warn-
ings on page 110.
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. Depending on the road surface conditions, the risk of skidding is reduced,
thereby improving the vehicle's driving stability .
The ESC system is automatically activated each time the ignition is switched on.

111
The direction which the driver wishes to take is determined based on the steering
111
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
111
skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light

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).
The ESC system cannot be deactivated. The 

In the event of an ESC fault, the ESC warning light illuminates in the instrument


Hydraulic Brake Assist (HBA)
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by very quick operation of the brake pedal. In order to ach-
ieve the shortest possible braking distance, the brake pedal must be applied firm-

ly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is released.
The ABS is activated faster and more effectively with the intervention of the HBA.
