3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-halfturn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
WARNING!
•If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resum-
ing acceleration, manually activate the trailer brake
or apply more vehicle brake pressure prior to releas-
ing the brake pedal.
• HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle. Also,
be certain to leave the transmission in PARK.
• Failure to follow these warnings can result in a
collision or serious personal injury.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel

7. When the NEUTRAL (N) indicator light turns off,release the NEUTRAL (N) button.
8. After the NEUTRAL (N) button has been released, the transfer case will shift to the position indicated by the
selector switch.
Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features two torque
transfer couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the Quadra-
Trac II transfer case. The optional ELSD axle is fully
automatic and requires no driver input to operate. Under normal driving conditions, the unit functions as a standard
axle, balancing torque evenly between left and right
wheels. With a traction difference between left and right
wheels, the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque will
automatically transfer from the wheel that has less traction,
to the wheel that has traction. While the transfer case and
axle coupling differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shifting informa-
tion, preceding this section, for shifting this system.
QUADRA-LIFT — IF EQUIPPED
Description
The Quadra-Lift air suspension system provides full time
load leveling capability along with the benefit of vehicle
height adjustment by the push of a button. The vehicle will
automatically raise and lower the ride height to adapt to
the appropriate driving conditions. At higher speeds, the
vehicle will lower to an aerodynamic ride height and when
operating in off-road modes, the vehicle will raise the ride
height accordingly. The buttons near the terrain switch in
the center console area can be used to set preferred ride
height to match the appropriate conditions.
NEUTRAL (N) Switch
288 STARTING AND OPERATING

The Selec-Terrain switch will automatically change the
vehicle to the optimized height based on the Selec-Terrain
switch position. The vehicle height can be changed from
the default height for each Selec-Terrain mode by normal
use of the air suspension switches. Refer to “Four Wheel
Drive Operation” in “Starting And Operating” for further
information.
When To Use 4WD LOW Range — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme situations
such as deep snow, mud, or sand where additional low
speed pulling power is needed. Vehicle speeds in excess of
25 mph (40 km/h) should be avoided when in 4WD LOW
range.
WARNING!
Do not drive in 4WD-LOW Range on dry pavement;
driveline damage may result. 4WD-LOW Range locks
front and rear drivelines together and does not allow
for differential action between the front to rear drive-
shafts. Driving in 4WD-LOW on pavement will cause
driveline binding; use only on wet or slippery surfaces.
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be considered
before entering the water.
NOTE:Your vehicle is capable of water fording in up to 20
inches (51 cm) of water, while crossing small rivers or
streams. To maintain optimal performance of your vehi-
cle’s heating and ventilation system it is recommended to
switch the system into recirculation mode during water
fording.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering, as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle. If you must drive through water, try
to determine the depth and the bottom condition (and
location of any obstacles) prior to entering. Proceed with
