• Power Steering System Over Temp —
If Equipped If the “POWER STEERING SYS-
TEM OVER TEMP” message and a
icon are displayed on the EVIC
screen, it indicates that extreme
steering maneuvers may have oc-
curred, which caused an over tem-
perature condition in the power steering sys-
tem. You will lose power steering assistance
momentarily until the over temperature condi-
tion no longer exists. Once driving conditions
are safe, then pull over and let vehicle idle.
After five minutes, the system will cool and return to normal operation. Refer to “Power
Steering” in “Starting and Operating” for further
information.
NOTE:
•
Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in
steering effort, especially at very low ve-
hicle speeds and during parking maneu-
vers.
• If the condition persists, see your autho-
rized dealer for service.

starter will disengage automatically in 20 sec-
onds. The starter can be disengaged by turn-
ing the ignition switch to the OFF position, if
required.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving. This
allows oil to circulate and lubricate the turbo-
charger.
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of idling
may be harmful to your engine because com-
bustion chamber temperatures can drop so low
that the fuel may not burn completely. Incom-
plete combustion allows carbon and varnish to
form on piston rings and injector nozzles. Also,
the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the
engine.
Engine Warm Up
Avoid full throttle operation when the engine is
cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.NOTE:
High-speed, no-load running of a cold en-
gine can result in excessive white smoke
and poor engine performance. No-load en-
gine speeds should be kept under 1,200
RPM during the warm-up period, especially
in cold ambient temperature conditions.
If temperatures are below 32°F (0°C), operate
the engine at moderate speeds for five minutes
before full loads are applied.
Engine Idling – In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of idling
may be harmful to your engine because com-
bustion chamber temperatures can drop so low
that the fuel may not burn completely. Incom-
plete combustion allows carbon and varnish to
form on piston rings and injector nozzles. Also,
the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the
engine.
Stopping The Engine
Before turning off your turbo diesel engine,
always allow the engine to return to normal idle
speed and run for several seconds. This as-sures proper lubrication of the turbocharger.
This is particularly necessary after any period
of hard driving.
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe-
cially important for turbocharged, charge air
cooled engines.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•
Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.

204

Five-Speed Automatic TransmissionThe electronically-controlled transmission pro-
vides a precise shift schedule. The transmis-
sion electronics are self-calibrating; therefore,
the first few shifts on a new vehicle may be
somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few
hundred miles/kilometers.
Gear Ranges
NOTE:
After selecting any gear range, wait a mo-
ment to allow the selected gear to engage
before accelerating. This is especially im-
portant when the engine is cold. If there is a
need to restart the engine, be sure to turn
the ignition switch to the LOCK position
before restarting. Transmission gear en-
gagement may be delayed after restarting
the engine if the ignition switch is not turned
to the LOCK position first.
PARK
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never use PARK while the
vehicle is in motion. Apply the parking brakewhen leaving the vehicle in this range. Always
apply the parking brake first, then place the
shift lever into the PARK position.
WARNING!
•
Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
• It is dangerous to move the shift lever out of
PARK or NEUTRAL if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse.
You could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and
when your right foot is firmly on the brake
pedal.
REVERSE
This range is for moving the vehicle backward.
Use only after the vehicle has come to a
complete stop. NEUTRAL
This range is used when vehicle is standing for
prolonged periods with engine running. Engine
may be started in this range. Set the parking
brake if you must leave the vehicle.
NOTE:
Towing the vehicle, coasting, or driving for
any other reason with the shift lever in
NEUTRAL can result in severe transmission
damage. Refer to “Recreational Towing” in
“Starting and Operating” and “Towing a Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE
This range should be selected only when the
vehicle is at a complete stop and the brakes
are firmly applied. The transmission automati-
cally upshifts through fifth gear. The DRIVE
position provides optimum driving characteris-
tics under all normal operating conditions.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows you to move the shift lever left (-) or right
(+) when the shift lever is in the DRIVE position,
allowing you to limit the highest available gear.
206

The “TOW/HAUL Indicator Light” will illuminate
in the instrument cluster to indicate when the
switch has been activated. Pressing the switch
a second time restores normal operation. If the
TOW/HAUL mode is desired, the switch must
be pressed each time the engine is started.
In high ambient temperatures with sustained
high engine speed and load, an upshift, fol-
lowed shortly thereafter by a downshift, may
occur. The “TOW/HAUL Indicator Light” will
turn off. This is a normal part of the overheat
protection strategy when operating in the TOW/
HAUL mode.
Transmission Limp Home Mode
Transmission function is monitored for abnor-
mal conditions. If a condition is detected that
could result in transmission damage, the Trans-
mission Limp Home Mode will be engaged. In
this mode, the transmission will remain in the
current gear (3.6L and 3.0L Diesel engine) or in
direct gear (5.7L engine) until the vehicle is
brought to a stop.To reset the transmission, use the following
procedure:
1. Stop the vehicle.
2. Move the shift lever into the PARK position.
3. Turn the engine off, and be sure to turn the
ignition switch to the LOCK position.
4. Wait approximately 10 seconds, then restart
the engine.
5. Move the shift lever to the desired gear
range.
If the problem is no longer detected, the trans-
mission will return to normal operation. If the
problem persists, PARK, REVERSE, and NEU-
TRAL will continue to operate. Only second
gear (3.6L and 3.0L Diesel engine) or third gear
(5.7L engine) will be available in the DRIVE
position. Have the transmission checked at
your authorized dealer as soon as possible.
Torque Converter Clutch
A feature, designed to improve fuel economy,
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically, at a cali-brated speed, at light throttle. It engages at
higher speeds under heavier acceleration. This
may result in a slightly different feeling or
response during normal operation in high gear.
When the vehicle speed drops below a cali-
brated speed, or during acceleration, the
clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not en-
gage until the transmission fluid and en-
gine coolant are warm [usually after 1 to
3 miles (1.6 to 4.8 km) of driving]. Because
the engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting into Overdrive when cold. This is
normal. Manually shifting (using the ERS
shift control) between 4 (direct gear) and
5/D (Overdrive gear) positions will dem-
onstrate that the transmission is able to
shift into and out of Overdrive. For ve-
hicles with 5.7L engines (which have two
Overdrive gears), the transmission may
not shift into the top Overdrive gear (nor-
mal fifth gear) until the transmission fluid
and engine coolant are warm.
209

When descending mountains or hills, repeated
braking can cause brake fade with loss of
braking control. Avoid repeated heavy braking
by downshifting the transmission whenever
possible.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to
check for damage. That way you can get any
problems taken care of right away and have
your vehicle ready when you need it.
•Completely inspect the underbody of your
vehicle. Check tires, body structure, steer-
ing, suspension, and exhaust system for
damage.
• Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness,
particularly on the chassis, drivetrain com-
ponents, steering, and suspension. Re-
tighten them, if required, and torque to the
values specified in the Service Manual. •
Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the ra-
diator, fan, brake rotors, wheels, brake lin-
ings, and axle yokes inspected and cleaned
as soon as possible.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking power
when you need it to prevent a collision. If you
have been operating your vehicle in dirty
conditions, get your brakes checked and
cleaned as necessary.
• If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material. Im-
pacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct
the situation.
POWER STEERING
3.6L Engine and 3.0L Diesel Engine
Your vehicle is equipped with an electro-
hydraulic power steering system that will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will vary its assist to provide light efforts while
parking and good feel while driving. If the
electro-hydraulic power steering system expe-
riences a fault that prevents it from providing
power steering assist, then the system will
provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the
electrically driven pump to reduce or stop
power steering assistance in order to prevent
damage to the system. Normal operation will
resume once the system is allowed to cool.
If the “SERVICE POWER STEER-
ING SYSTEM” message and a
flashing icon are displayed on the
EVIC screen, it indicates that the
vehicle needs to be taken to the
220

dealer for service. It is likely the vehicle has lost
power steering assistance. Refer to “Electronic
Vehicle Information (EVIC)” in “Understanding
Your Instrument Panel” for further information.
If the “POWER STEERING SYSTEM OVER
TEMP” message and an icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing maneuvers may have occurred, which
caused an over temperature condition in the
power steering system. You will lose power
steering assistance momentarily until the over
temperature condition no longer exists. Once
driving conditions are safe, then pull over and
let vehicle idle for a few moments until the light
turns off. Refer to “Electronic Vehicle Informa-
tion (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in
steering effort, especially at very low ve-
hicle speeds and during parking maneu-
vers. •
If the condition persists, see your autho-
rized dealer for service.
5.7L EngineThe standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and
during parking maneuvers.
NOTE:
• Increased noise levels at the end of the
steering wheel travel are considered nor-
mal and do not indicate that there is a
problem with the power steering system.
• Upon initial start-up in cold weather, the
power steering pump may make noise for
a short amount of time. This is due to the
cold, thick fluid in the steering system. This noise should be considered normal,
and it does not in any way damage the
steering system.WARNING!
Continued operation with reduced power
steering assist could pose a safety risk to
yourself and others. Service should be ob-
tained as soon as possible.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will in-
crease the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.
Power Steering Fluid CheckChecking the power steering fluid level at a
defined service interval is not required. The
fluid should only be checked if a leak is sus-
pected, abnormal noises are apparent, and/or
the system is not functioning as anticipated.
Coordinate inspection efforts through an autho-
rized dealer.

ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving ma-
neuvers. It cannot prevent wheel lift due to
other factors such as road conditions, leaving
the roadway or striking objects or other ve-
hicles.
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence
the chance that wheel lift or rollover may
occur. ERM cannot prevent all wheel lift or
rollovers, especially those that involve leaving
the roadway or striking objects or other ve-
hicles. 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.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel to assist incounteracting the oversteer or understeer con-
dition. 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
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more
than appropriate for the steering wheel po-
sition.
• Understeer - when the vehicle is turning less
than appropriate for the steering wheel po-
sition.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will start
to flash as soon as the tires lose traction and
the ESC system becomes active. The “ESC
Activation/Malfunction Indicator Light” also
flashes when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” begins
to flash during acceleration, ease up on the
accelerator and apply as little throttle as pos- sible. Be sure to adapt your speed and driving
to the prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from act-
ing on the vehicle, nor can it increase the
traction afforded by prevailing road condi-
tions. ESC cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. The capabilities 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 two available operating
modes in 4WD HIGH range, and one operating
mode in 4WD LOW range.
