150 Starting and driving<br />

StabiliTrak ® 3<br />

Anti-skid system<br />

WARNING<br />

When driving normally, the StabiliTrak ®<br />

system improves the car’s stability. This<br />

must not, however, be regarded as a<br />

reason to maintain higher speeds. Maintain<br />

the same precautions as normal to<br />

ensure safe cornering and safe driving on<br />

slippery roads.<br />

StabiliTrak uses functions from the Anti-lock<br />

Braking System (ABS) and Traction Control<br />

System (TCS) to help the driver stabilise the<br />

car in unexpected driving situations that<br />

would otherwise be difficult to manoeuvre.<br />

The illustration shows how the system<br />

brakes one or more wheels (and with varying<br />

braking force for each wheel) in order<br />

to increase the car’s chances of following<br />

the direction in which the driver wants to<br />

drive.<br />

How the StabiliTrak ® system<br />

works<br />

StabiliTrak ® can help to prevent the car from<br />

skidding by braking one or more wheels<br />

regardless of whether the driver is<br />

depressing the brake pedal. Engine output<br />

is also choked to reduce any drive wheel<br />

spin. The car has sensors that measure<br />

wheel speed, yaw angle rate, lateral acceleration,<br />

steering wheel angle and brake<br />

pressure. Signals from these sensors are<br />

used to calculate the course of the vehicle,<br />

the driver’s intentions and whether the<br />

StabiliTrak ® system should be deployed.<br />

The course of the vehicle is compared to the<br />

course selected by the driver via the<br />

steering wheel. If these values do not<br />

match, the StabiliTrak ® function comes into<br />

action.<br />

StabiliTrak ® gives the driver a greater<br />

chance of maintaining control of the car in a<br />

critical situation.<br />

StabiliTrak ® indicator light<br />

When the remote control is turned to position<br />

3, the lamp is lit for about 4 seconds<br />

while the system performs self-diagnosis.<br />

in the main instrument panel illuminates<br />

for a brief period when the<br />

StabiliTrak ® system regulates.<br />

If the StabiliTrak ® system comes into action,<br />

The friction limit for the tyre/road surface<br />

has been exceeded. Take extra care as you<br />

continue to drive.
