Traction Control (Tc) - Porsche CARRERA GT-2004 Manual

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).
