WARNING!(Continued)
•Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.
NOTE: The HSA system may also be turned on and off if
the vehicle is equipped with the Electronic Vehicle Infor-
mation Center (EVIC). Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your Instru-
ment Panel” for further information.
HSA Off
If you wish to turn off the HSA system, follow this
procedure: 1. Start with the engine off and vehicle in PARK (auto-
matic transmission) or NEUTRAL with clutch out
(manual transmission) with wheels straight. Apply
parking brake on manual transmission vehicle.
2. Start the engine.
3. With the engine running, the brake applied, and the clutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESC OFF switch four times within twenty seconds.
5. Rotate the steering wheel 360° clockwise (180° clock- wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the “ESC Activation/Malfunction Indicator Light” will blink
several times to confirm HSA is off.
472 STARTING AND OPERATING

Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle’s speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers.
Electronic Roll Mitigation (ERM) can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors such as road conditions, leaving the road-
way or striking objects or other vehicles.NOTE:
Anytime the ESC system is in the “Full Off”
mode, ERM is disabled. Refer to Electronic Stability
Control (ESC) for a complete explanation of the available
ESC modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. Electronic Roll
Mitigation (ERM) cannot prevent all wheel lift or
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the safety
of others.

STARTING AND OPERATING 473

Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by apply-
ing the brake of the appropriate wheel to assist in
counteracting the over/under steer condition. Engine
power may also be reduced to help the vehicle maintain
the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position. The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster), starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in

WARNING!(Continued)
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user ’s safety or the safety of
others.
The ESC system has three available operating modes in
4H range. The system has one operating mode in 4L
range. Two-wheel drive vehicles and four-wheel drive
vehicles in 2H range have two operating modes.
4H Range (4WD Models)
On
This is the normal operating mode for ESC in 4H range.
Partial Off
This mode is entered by momentarily pressing the ESC
OFF switch. When in Partial Offmode, the TCS portion
of ESC (except for the limited slip feature described in the
TCS section), has been disabled and the ESC Off Indica-
tor Light will be illuminated.
5
STARTING AND OPERATING 475

This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin
than ESC would normally allow is required to gain
traction. To turn ESC on again, momentarily press the
ESC OFF switch. This will restore the normal “ESC On”
mode of operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESC OFF switch. Once the situation
requiring ESC to be switched to the “Partial Off” mode is
overcome, turn ESC back on by momentarily pressing the
ESC OFF switch. This may be done while the vehicle is in
motion.WARNING!
• When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the “ESC Off Indicator Light” will be illuminated.
When in “Partial Off” mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC sys-
tem is reduced.
• Trailer Sway Control (TSC) is disabled when the
ESC system is in the Partial Offmode.
ESC Off
This mode is entered by pressing and holding momen-
tarily pressing the ESC OFF switch for five seconds.

STARTING AND OPERATING 479

NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to the
ON/RUN position.
• Each time the ignition is cycled to the ON/RUN
position, the ESC system will be ON even if it was
cycled off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. TSC cannot stop all trailers
from swaying. Always use caution when towing a trailer
and follow the tongue weight recommendations. Refer to
“Trailer Towing” in “Starting and Operating” for further
information. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash, the
engine power may be reduced and you may feel the
brakes being applied to individual wheels to attempt to
stop the trailer from swaying. TSC is disabled when the
ESC system is in the “Partial Off” or “Full Off” modes.

STARTING AND OPERATING 481

However, the driver can override HDC operation by
applying the brake to slow the vehicle down below the
HDC control speed. If more speed is desired during HDC
control, the accelerator pedal will increase vehicle speed
in the usual manner. When either the brake or the
accelerator is released, HDC will control the vehicle at the
original set speed.
Enabling HDC
1. Shift the transfer case into 4WD LOW range. Refer to“Four-Wheel Drive Operation” in “Starting and Oper-
ating” for further information.
2. Press the “Hill Descent” button. The “Hill Descent Control Indicator Light” in the instrument cluster will
turn on solid. NOTE:
•If the transfer case is not in 4WD LOW range, the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will not be enabled.
• If the ESC senses that the brakes are overheating the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will become deactivated until
the brakes have cooled.
Disabling HDC
Press the “Hill Descent” button or shift the transfer case
out of 4WD LOW range. The “Hill Descent Control
Indicator” light in the instrument cluster will turn off.

Spare Tires — If Equipped
NOTE:For vehicles equipped with TIREFIT instead of a
spare tire, please refer to “TIREFIT KIT” in “What To Do
In Emergencies” for further information.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact, full size or limited-use temporary spare
installed. Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And
Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear axle
of your vehicle. This spare tire may be used in the tire rotation for your vehicle. If your vehicle has this option,
refer to an authorized tire dealer for the recommended
tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use only.
You can identify if your vehicle is equipped with a
compact spare by looking at the spare tire description on
the Tire and Loading Information Placard located on the
driver ’s side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the letter “T”
or “S” preceding the size designation. Example: T145/
80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and reinstalled
on your vehicle at the first opportunity.
5
STARTING AND OPERATING 501

Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare tire.
Do not install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact spares are for temporary emergency use
only. With these spares, do not drive more than
50 mph (80 km/h). Temporary use spares have limited
tread life. When the tread is worn to the tread wear
indicators, the temporary use spare tire needs to be
replaced. Be sure to follow the warnings, which
apply to your spare. Failure to do so could result in
spare tire failure and loss of vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only.
This tire may look like the originally equipped tire on thefront or rear axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the tread is worn
to the tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency
use only. This tire is identified by a label located on the
limited-use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited-use spare
tire affects vehicle handling. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
