Ride Control Systems
The vehicle has a Traction Control System (TCS) and StabiliTrak/ Electronic Stability Control (ESC), an electronic stability control system. These systems help limit wheel spin and assist the driver in maintaining control, especially on slippery road conditions.
TCS activates if it senses any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin.
StabiliTrak/ESC activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling.
StabiliTrak/ESC selectively applies braking pressure to any one of the vehicle wheel brakes to assist the
driver in keeping the vehicle on the intended path. Trailer Sway Control (TSC) is also on automatically when the vehicle is started. See Trailer Sway Control (TSC) 0 316.
If cruise control is being used and traction control or StabiliTrak/ESC begins to limit wheel spin, cruise control will disengage. Cruise control may be turned back on when road conditions allow.
Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle.
It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow.
See If the Vehicle Is Stuck 0 237 and “Turning the Systems Off and On” later in this section.
When the transfer case (if equipped) is in Four-Wheel Drive Low, the stability system is automatically disabled, 
comes on, and the appropriate message will appear on the DIC. Both traction control and StabiliTrak/ESC are automatically
disabled in this condition.
The indicator light for both systems is in the instrument cluster. This light will:
If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and
d comes on and stays on to
indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.
If d comes on and stays on:
Drive the vehicle. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer.
The button for TCS and StabiliTrak/ ESC is on the center stack.
To turn off only TCS, press and release 
. The traction off light i displays in the instrument cluster.
The appropriate message will display in the DIC. To turn TCS on again, press and release 
. The traction off light i displayed in the
instrument cluster will turn off.
If TCS is limiting wheel spin when 
is pressed, the system will not turn off until the wheels stop spinning.
To turn off both TCS and StabiliTrak/ ESC, press and hold 
until the traction off light i and the
StabiliTrak/ESC OFF light 
come on and stay on in the instrument cluster, then release. The
appropriate message will display in the DIC.
To turn TCS and StabiliTrak/ESC on again, press and release 
. The traction off light i and the
StabiliTrak/ESC OFF light 
in the instrument cluster turn off.
StabiliTrak/ESC will automatically turn on if the vehicle exceeds
56 km/h (35 mph). Traction control will remain off.
The vehicle has a Trailer Sway Control (TSC) feature and a Hill Start Assist (HSA) feature.
See Trailer Sway Control (TSC) 0 316 or Hill Start Assist (HSA) 0 272.
Adding accessories can affect the vehicle performance. See Accessories and Modifications
0 326.
If equipped, Hill Descent Control (HDC) sets and maintains vehicle speed while driving down steep
grades in a forward or reverse gear. The HDC switch is on the center stack, below the climate controls.
Press 5 to enable or disable HDC. Vehicle speed must be below
50 km/h (31 mph).
When enabled, the HDC light displays on the instrument cluster.
A blinking HDC light indicates the system is actively applying the brakes to maintain vehicle speed. HDC can maintain vehicle speeds between 1 and 30 km/h (1 and
19 mph) on grades greater than or equal to 10%.
If HDC is to be used for more than three minutes or on grades steeper than 25%, the transfer case should be put into Four-Wheel Drive Low (4 n) to reduce the possibility of
brake overheating.
Noise from the hydraulic brake control module is normal when HDC is active.
When HDC is activated, the initial HDC speed is set to the current driving speed. It can be increased or decreased by pressing +RES or SET- on the steering wheel, or by applying the accelerator or brake pedal. This adjusted speed becomes the new set speed.
HDC will remain enabled between 30 and 60 km/h (19 and 37 mph); however, vehicle speed cannot be set or maintained in this range. HDC will automatically disable if the vehicle speed is above 80 km/h
(50 mph) or above 60 km/h
(37 mph) for at least 30 seconds.
5 must be pressed again to
re-enable HDC. HDC may disable after an extended period of use.
If this happens, HDC will require time to cool down. The length of time HDC remains active depends on road conditions, grade, set speed, vehicle loading, and outside temperature.
When enabled, if the vehicle speed is above 30 km/h (19 mph) and below 60 km/h (37 mph), a DIC message will display.
Vehicles with a locking rear axle can give more traction on snow, mud, ice, sand, or gravel. It works like a standard axle most of the time, but when traction is low, this feature will allow the rear wheel with the most traction to move the vehicle.
