We recommend having this resetting performed by a specialist garage.
The specialist garage:

resets the memory of the display after the appropriate inspection;

makes an entry in the Service schedule;

affix the sticker with the entry of the following service interval to the side of the
dash panel on the driver's side.
The service interval display can also be reset with the reset button as follows

fault in the system.
The fact that the ESP system operates together with the ABS and the EDL means that
the ESP warning light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the ESP system
can be switched off for technical reasons. In this case, the ESP system can be switched
on again by switching the ignition on and off. If the warning light goes out, the ESP
system is fully functional again.
Further information on the ESP page 123, “Electronic stability programme (ESP)*”.
Note
If the battery has been disconnected and reconnected, the warning light
 comes on
after switching on the ignition. The warning light must go out after driving a short
distance.
Alternator

The warning light
 comes on after the ignition has been switched on. It should go
out after the engine has started.
If the warning light does not go out after the engine has started, or comes on when
driving, drive to the nearest specialist garage. The vehicle battery will be discharged in
this case so switch off all non-essential electrical components.
A peep sounds as an additional warning signal.
Caution
If the warning light
 comes on when driving and in addition the warning light

(cooling system fault) also comes on in di splay, you must then stop the car immedi-
ately and switch the engine off - risk of engine damage!
Brake system

The warning light
 comes on for several seconds afte r the ignition is switched on.
If the warning light  stays on when the ignition is switched on or comes on while
driving, there is a fault in the brake system. Visit the nearest specialist garage immedi-
ately and have the brake system inspected.

One should get used to high pedal forces, long braking distances and long free play of
the brake pedal when driving to the next specialist garage.

Technical Data
Traction control system (TCS)
The traction control system prevents the driven wheels from spinning
when accelerating.General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when th e engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the ABS
sensors. If the wheels are spinning, the force transmitted to the road surface is auto-
matically adapted by reducing the engine speed. The system operates at all speeds.
The TCS operates in combination with the ABS page 126, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instru ment cluster when there is a fault on the
TCS page 31.
Switching off
You can switch the TCS off and on again as you wish by pressing the button fig. 135 .
The TCS warning light lights up in the instru ment cluster when the system is switched
off page 31.
The TCS should normally always be switched on. It may be good practice in certain
exceptional cases, such as when you wish to have wheel slip, to switch off the system. Examples:

when driving with snow chains

when driving in deep snow or on a loose surface

when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road
surface and the traffic situation. The increased safety offered must not tempt
you to take greater risks than otherwise - risk of an accident!
Note

All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the TCS. Differing rolling circumferences of the tyres can lead to an unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the TCS page 166, “Accesso-
ries, changes and replacement of parts”.
BrakesWhat has a negative effect on braking efficiency?Wear-and-tear
Wear-and-tear to the brake pa ds is greatly dependent on the operating conditions of
the vehicle and your style of driving. Particularly if you drive a great deal in towns and
over short distances or if you adopt a sporty style of driving, it may be necessary to
have the thickness of the brake pads insp ected at a specialist garage between the
service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect un der certain conditions
such as when driving through water, during heavy rain showers or after the vehicle has
been washed in an automatic vehicle wash , since the brake discs and brake pads may
