Starting and driving
StabiliTrak
®
3
Anti-skid system
StabiliTrak uses functions from the Anti-lock
Braking System (ABS) and Traction Control
System (TCS) to help the driver stabilise the
car in unexpected driving situations that
would otherwise be difficult to manoeuvre.
How the StabiliTrak
®
system
works
StabiliTrak
®
can help to prevent the car from
skidding by braking one or more wheels
regardless of whether the driver is
depressing the brake pedal. Engine output
is also choked to reduce any drive wheel
spin. The car has sensors that measure
wheel speed, yaw angle rate, lateral accel-
eration, steering wheel angle and brake
pressure. Signals from these sensors are
used to calculate the course of the vehicle,
the driver’s intentions and whether the
StabiliTrak
®
system should be deployed.
The course of the vehicle is compared to the
course selected by the driver via the
steering wheel. If these values do not
match, the StabiliTrak
®
function comes into
action.
StabiliTrak
®
gives the driver a greater
chance of maintaining control of the car in a
critical situation.

indicator light
When the remote control is turned to posi-
tion 3, the lamp is lit for about 4 seconds
while the system performs self-diagnosis.
in the main instrument panel illumi-
nates for a brief period when the
StabiliTrak
®
system regulates.
If the StabiliTrak
®
system comes into action,
The friction limit for the tyre/road surface
has been exceeded. Take extra care as you
continue to drive.
WARNING
When driving normally, the StabiliTrak
®
system improves the car’s stability. This
must not, however, be regarded as a
reason to maintain higher speeds. Main-
tain the same precautions as normal to
ensure safe cornering and safe driving on
slippery roads.
The illustration shows how the system
brakes one or more wheels (and with var-
ying braking force for each wheel) in order
to increase the car’s chances of following
the direction in which the driver wants to
drive.
