Traction Control (TC)

TC counteracts the spinning of the driven wheels

when moving off and accelerating.

Driving stability and traction are improved over the

entire speed range.

Warning!

The increased control that is provided should

not induce you to take greater risks with your

safety. The limits dictated by the laws of

physics cannot be overcome, even with TC.

The risk of accidents due to inappropriate

speed cannot be reduced, even by the TC.

The driver bears the responsibility for all

driving maneuvers.
f Adapt your driving style to the prevailing road

and weather conditions.

f Obey all traffic laws.

Readiness for operation

TC is switched on automatically every time you

start the engine.

Function

Engine torque control
When the wheel rotation speed of the front and

rear axles differs by more than a specified value

(spinning), this is detected by TC system and

engine output is automatically reduced.

Brake control
In addition to reducing engine power, TC brakes

the spinning drive wheels.

Simultaneous spinning of both drive wheels does

not result in brake intervention.

This means: driving stability is not moni-

tored.
The events below inform the driver of TC control

operations and warn him to adapt his driving style

to the road conditions:
– The information light in the instrument panel

lights up

– Hydraulic noises can be heard
– Reduced engine power

Switching off Traction Control

f Press the “TC OFF” logo of the A button.

TC is switched off after a short delay.

With TC switched off, the TC OFF warning light

on the instrument panel lights up.

Note on operation
TC cannot be switched off during a controlled

braking process (information light on).
