Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
80
Antilock Braking System (ABS)
81
Traction Control System (TCS)
81
Electronic Differential Lock (EDL)
81WARNING■ 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 » page 110, Modifications, adjustments
and technical alterations .
■
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 19 .
Electronic Stability Control (ESC)
First read and observe the introductory information and safety warn-
ings
on page 80.
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 conditions of the road surface, the risk of skidding is re-
duced, 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 actualbehaviour of the vehicle. In the event of deviations, such as the car beginning to
skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light
flashes in the instru-
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
illuminates in the instru-
ment cluster » page 18.
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.
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 brakepedal for approx. 2 seconds after the brake pedal is released.
80Driving

The brake pressure drops gradually the more you operate the accelerator pedal. Ifthe vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active as of a 5 % slope, if the driver door is closed. HHC is always only active on slopes when in forward or reverse start off. When driving downhill, it isinactive.
Antilock Braking System (ABS)
First read and observe the introductory information and safety warn-
ings
on page 80.
ABS prevents the wheels locking when braking. Thus helping the driver to main-
tain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of the
brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pressure
on the brake pedal.
Traction Control System (TCS)
First read and observe the introductory information and safety warn-
ings
on page 80.
If the wheels are slipping, the TCS adapts the engine speed to the conditions of
the road surface. The TCS makes it much easier to start off, accelerate and climb
steep hills even if the conditions of the road surface are unfavourable.
The TCS function is automatically activated each time the ignition is switched on.
During an intervention of the system, the warning light flashes in the instru-
ment cluster.
If there is a fault in the TCS, the warning light then lights up in the instrument cluster
» page 19 .
Electronic Differential Lock (EDL)
First read and observe the introductory information and safety warn-
ings
on page 80.
If one of the wheels starts to spin, the EDL system brakes the spinning wheel and transfers the driving force to the other wheels. This ensures the stability of the
vehicle and a quick journey.
The EDL switches off automatically in order to avoid excessive heat generation
on the brake of the wheel 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.
Parking aid
Introduction
This chapter contains information on the following subjects:
Function
82
Visual parking system
82WARNING■ The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when reversing the vehicle
or carrying out similar manoeuvres. Pay particular attention to small children
and animals as they are not recognised by the parking aid sensors.■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer drawbars etc. behind your vehicle. Such ob-
stacles may not be recognised by the parking aid sensors.
■
Under certain circumstances, surfaces of certain objects and types of cloth-
ing cannot reflect the system signals. Thus, these objects or people who wear
such clothing are not recognised by the System sensors.
■
External sound sources can have a detrimental effect on the system. Under
adverse conditions, this may cause objects or people to not be recognised by the system.
