WARNING!
²Always fully apply the parking brake when leav-
ing your vehicle, or the vehicle may roll and cause
damage or injury. Also be certain to leave an
automatic transmission in Park. Failure to do so
may cause the vehicle to roll and cause damage or
injury.
²Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
failure and an accident.
²Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don't leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
BRAKE SYSTEM
In the event power assist is lost for any reason, (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be significantly increased over that
required with the power system operating.
If either the front or rear hydraulic systems lose normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning Light and the ABS Light during brake use.
Four-Wheel Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
290 STARTING AND OPERATING
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
ªPartial Offº mode. Refer to ªESP (Electronic Stability
Program)º in this Section. This brake pressure modula-
tion transfers drive torque from slipping to non-slipping
wheels to provide optimal forward traction.
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 vehicles 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.
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 roadway or striking objects or
other vehicles.
STARTING AND OPERATING 297

WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur.
²ERM cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. Only a safe,
attentive, and skillful driver can prevent accidents.
²The 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.
Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP 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, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
298 STARTING AND OPERATING
4WD/4WD LOCK or 2WD Models
ON
This is the normal operating mode for ESP in 4WD LOCK
and in 2WD vehicles. Whenever the vehicle is started or
the transfer case (if equipped) is shifted from 4WD LOW
or NEUTRAL back to 4WD LOCK, the ESP system will be
in this mode. This mode should be used for almost all
driving situations. ESP should only be turned to ªPartial
Offº for specific reasons as noted below.
This mode is entered by momentarily
depressing the ESP OFF Control
Switch. When in ªPartial Offº mode,
the engine management portion of
ESP has been desensitized, the thresh-
olds for ESP activation are raised, and
the ªESP/TCS Indicator Lightº will be
illuminated. This mode is intended to
be used if the vehicle is in deep snow,sand or gravel conditions and more wheel spin than ESP
would normally allow is required to gain traction. Trailer
Sway Control (TSC) is not available when the system is in
the9Partial Off9mode. To turn ESP on again, momen-
tarily depress the ESP OFF Control Switch. This will
restore the normal ON mode of operation. ESP always
operates under braking, even with the switch in the OFF
position.
WARNING!
In the ªPartial Offº mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.
Partial Off
300 STARTING AND OPERATING
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 ªPartial Offº
mode by pressing the ESP Control Switch. Once the
situation requiring ESP to be switched to the ªPartial Offº
mode is overcome, turn ESP on by momentarily depress-
ing the ESP Control Switch. This may be done with the
vehicle in motion.
4WD LOW Range
Partial Off
This is the normal operating mode for ESP in 4WD LOW.
Whenever the vehicle is started in 4WD LOW or the
transfer case (if equipped) is shifted from 4WD LOCK or
NEUTRAL to 4WD LOW, the ESP system will be in this
mode. In 4WD LOW, ESP function is desensitized until
the vehicle reaches a speed of 30 mph (48 km/h). At 30
mph (48 km/h) the normal ESP stability function returns
and the ESP/TCS Indicator Light turns off. When thevehicle speed drops below 25 mph (40 km/h) the ESP
system goes back to Partial Off. ESP is desensitized at low
vehicle speeds in 4WD LOW so that it will not interfere
with off road driving but ESP function returns to provide
the stability feature at speeds above 30 mph (48 km/h).
The ABS is in a special Off Road mode that allows wheels
to lock at lower speeds if gravel is detected to shorten
stopping distances.
NOTE:When the vehicle is in 4WD LOW, a feature of
the ESP system remains active whether the ESP is on or
off. This feature functions similar to a limited slip differ-
ential and controls the wheel spin across an axle. If one
wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel and
allow more engine torque to be applied to the wheel that
is not spinning.

WARNING!
In the Partial Off mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
ESP/BAS Warning Lamp and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ESP/BAS Warning Light
and the yellow ESP/TCS Indicator Light in the instru-
ment cluster both come on when the ignition switch is
turned to the ON position. They should both go out with
the engine running. If the ESP/BAS Warning Light comes
on continuously with the engine running, a malfunction
has been detected in either the ESP or BAS system, or
both. If this light remains on after several ignition cycles,and the vehicle has been driven several miles at speeds
greater than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
NOTE:
²The ESP Indicator Light and the ESP/BAS Warning
Light come on momentarily each time the ignition
switch is turned ON.
²Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
²The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize a swaying
trailer and will take the appropriate actions to attempt to
302 STARTING AND OPERATING
stop the sway. The system will reduce engine power and
apply individual brakes that will counter act the sway of
the trailer. TSC will become active automatically once the
swaying trailer is recognized. No driver action is re-
quired. TSC cannot stop all trailers from swaying. Al-
ways use caution when towing a trailer and follow the
tongue weight recommendations. For additional infor-
mation on towing a trailer with your vehicle, refer to
9Trailer Towing9in Section 5.
MULTI-DISPLACEMENT SYSTEM (MDS) Ð 5.7L
ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine's eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.

Compact Spare Tire Ð If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
WARNING!
Temporary use spare tires are for emergency use only.
With these tires, do not drive more than 50 mph (80
km/h). Temporary use spare tires 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.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.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited-Use Spare Ð If Equipped
The limited-use spare tire is for temporary emergency
use on your vehicle. This tire is identified by a limited-
