TRACTION CONTROL SYSTEM

(Two–wheel drive models)
The traction control system automatically helps prevent
the spinning of front wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to "ON", the system
automatically turns on.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power against front wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.
