Stability Traction Control (STC)
The STC system is designed to help reduce wheel spin by limiting power to the drive wheels if they
begin to lose traction. At speeds over 25 mph (40 km/h), the STC system monitors and compares all four
wheels. If one of the drive (front) wheels shows any tendency to slip, such as when driving on slippery
roads, the difference in speed is immediately detected. This triggers a signal to the engine management
system, which will reduce engine torque (by reducing fuel) until the differential is corrected. This torque
reduction is handled in stages, and reaction time is extremely fast. The system can be switched on or off
by pressing the button on the center console for at least half a second (see
page 27). The indicator light (
) in the instrument panel will be ON when you have switched the system off. The STC system
comes on each time you start your car.
The STC indicator light (
) will come on for approximately 2 seconds when the engine is started as
the system performs a self-diagnostic test.
This system should be switched off if you, for any reason, temporarily have to drive with tires of
different dimensions (e.g., spare tire).
The
symbol will flash when STC is actively regulating power to the drive wheels. Normal power
may be reduced at this time. This is normal as power is momentarily reduced to help keep the drive
wheels from losing traction and spinning.
If the STC system has been switched on using the button in the center console (the indicator light
will normally go off) and the indicator light remains on, there is a fault in the system. In this case:
· Stop the car in a suitable place and switch off the engine.
· Restart the engine.
· If the indicator light goes off, no further action is required.
