Traction Control
Traction Control ELECTRONIC TRACTION CONTROL*
The purpose of electronic traction control is to aid traction,
thereby helping the driver to maintain control of the car in
situations where one or both of the driving wheels are spinning
(for example, if one wheel is on ice and the other on tarmac).
The traction control system monitors the driving speed of each
wheel individually. If spin is detected on one wheel, the system
automatically brakes that wheel, transferring torque to the
opposite, non-spinning, wheel. If both wheels are spinning, the
system will reduce engine speed in order to regulate wheel rotation
until traction is regained.
NOTE: The individual wheel braking feature of the traction control
system will not operate at road speeds above 100 km/h. The engine torque
reduction feature continues to function up to the car’s maximum speed.
Warning light
On cars equipped with the standard instrument panel
(no message centre), the light flashes while the traction
control system is operating (cars equipped with a message centre
feature a traction control message, which appears for a minimum
of 4 seconds).
The light also illuminates as a bulb check (for approximately 3
seconds) when the starter switch is turned on and illuminates
continuously whenever traction control is manually disabled. If
there is a fault with the system, the warning light will fail to
extinguish and remains illuminated even when the car is stationary.
In this case you should seek qualified assistance at the earliest
opportunity.
Manual override
Traction control is entirely automatic in operation. However, the
system can be manually overridden by pressing the traction control
disable switch (see illustration). The system will then remain
disabled until the switch is pressed a second time, or until the
starter switch is turned off.
NOTE: When driving with snow chains fitted, it is recommended that
traction control be disabled.
