WARNING (Continued)
● Even though braking assist systems are extremely effective and help
control the vehicle in difficult situations, remember that the vehicle sta-
bility depends on tyre grip.
● When accelerating on a slippery surface, for example on ice and
snow, press the accelerator carefully. The wheels can still slip even with
braking assist systems resulting in loss of vehicle control.
WARNING
The effectiveness of the ESP* can be considerably reduced if other com-
ponents and systems affecting driving dynamics are not maintained or
are not functioning correctly. This includes, among others, brakes, tyres
and other systems already mentioned.
● Remember that changing and fitting other components to the vehicle
can affect operation of the ABS, BAS, ASR TC, EDL and ESP*.
● Changes to the vehicle suspension or using unapproved wheel/tyre
combinations can affect operation of the ABS, BAS, ASR, TC, EDL and
ESP* and their effectiveness.
● Likewise, the effectiveness of ESP* depends on the use of suitable
tyres ⇒ p age 201.
Note
To ensure that the ESP*, ASR and TCS work properly, all four wheels must be
fitted with identical tyres. Any differences in the rolling radius of the tyres
can cause the system to reduce engine power when this is not desired.
Note
If a malfunction should occur in the ABS, the ESP*, ASR, TC and EDL will al-
so be affected.

Noises may be heard while any of the above systems are operating.
Brake fluid
In the course of time, the brake fluid absorbs water from the ambient air. If
there is too much water contained in the brake fluid, the brake system could
be damaged. In addition, the boiling point of the brake fluid is significantly
lowered. When the brake fluid contains too much water and the brakes are
subject to considerable forces, bubbles of water vapour can form in the sys-
tem. These bubbles of water vapour can significantly reduce braking power,
notably increasing braking distance, and could even result in the total fail-
ure of the brake system. Ensuring that the brake system is always function-
ing correctly is essential for your own safety and the safety of other road
