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 manufac-
■
turer 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
and 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)

Read and observe and
The ESC system helps to maintain control of the vehicle in situations where it
is being operated at its dynamic limits, such as a sudden change in the direc-
tion 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.
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. In the event of deviations occurring, such
as the car beginning to skid, the ESC system will automatically brake the ap-
propriate wheel.

Antilock brake system (ABS),
›
Traction control (TCS),
›
Electronic Differential Lock (EDL)

Hill Hold Control (HHC).
The ESC system cannot be deactivated. The 
can only be used to deactivate the TCS. The

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
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is re-
leased.
The ABS is activated faster and more effectively with the intervention of the
HBA.
Hill Hold Control (HHC)
When driving on slopes, HHC allows you to move your foot from the brake ped-
al 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.
