Automatic Transmission

Electronic Range Select mode that

a lower or higher driving gear using the
+ / – button on the side of the shift lever.
The display on the instrument panel clus-
ter will show the current gear selection.
The transmission will be limited to the
gear selected and lower gears. Gears
higher than the gear selected will not be

If current vehicle speed is too high or
too low for the requested gear, the shift
will not occur.

StabiliTrak ®

– Stability Control

System

StabiliTrak is an advanced computer-
controlled vehicle stability and traction
enhancement system that assists with
directional control of the vehicle in
difficult driving conditions. It turns on
automatically every time you start your
vehicle.
To limit wheelspin and help maintain
directional control, you should always
leave the system on. However, if your
vehicle becomes stuck and rocking the
vehicle is required,
the system should be
turned off.
To turn off the traction
control part of the
system, press the
(Traction Control) button located on the
center console in front of the shift lever.
When the system is turned off, the
Traction Control light will illuminate.
See Section 4 of your Owner Manual.

The Tow/Haul mode (if equipped) assists
when pulling a heavy trailer by reducing
the frequency of transmission shifts and
improves the control of vehicle speed.
To turn on this feature,
press the (Tow/
Haul) button located on
the center console in
front of the shift lever.
Press it again to turn off the feature.
