Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Excess wheel spin is
controlled through engine torque reduction. This is realized via the fully
electronic spark and fuel injection systems. This process is very sensitive
to driving conditions and very fast acting. The rear wheels ªsearchº for
optimum traction several times a second and adjustments are made
accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Controlyoperation the engine will not ªrev-upº when
you push further on the accelerator. This is normal system behavior.
If you should become stuck in deep
snow or on a very slippery road
surface, try switching the Traction
Controlysystem off. This may allow
excess wheel spin to ªdigº the
vehicle out or enable a successful
ªrockingº maneuver.
TRACTION-LOK AXLE
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
If a single drive wheel should spin-up, the Traction-Lok axle will transfer
torque to the other wheel if it has traction.
Extended use of other than the manufacturer's specified size tires on a
Traction-Lok rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
To avoid injury, never run the engine with one wheel off the
ground, such as when changing a tire.
