StabiliTrak, the TCS/StabiliTrak light
comes on and the system is not
operational. See Electronic Stability
Control (ESC)/Traction Control
System (TCS) Indicator/Warning
Light on page 4‑22

Limited-Slip Differential

Vehicles with a limited-slip
differential can give more traction on
snow, mud, ice, sand or gravel.
It works like a standard differential
most of the time, but when traction
is low, this feature allows the drive
wheel with the most traction to
move the vehicle.

Selective Ride Control

The vehicle may have a ride control
system called Selective Ride
Control. The system provides the
following performance benefits:

.

Reduced Impact Harshness

.

Improved Road Isolation

.

Improved High-Speed Stability

.

Improved Handling Response

.

Better Control of Body Ride
Motions

To switch from TOUR to SPORT
mode, move the shift lever to the
left while the transmission is in
D (Drive).
