as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. Refer to “Electronic Vehicle Information Cen-
ter”.

This area will display the EVIC reconfigurable white
telltales. For further information, refer to “Electronic
vehicle Information Center (EVIC)”.14. 4 LOW
This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
15. Hill Descent Indicator — If Equipped The symbol illuminates (is armed) when the

passH,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
•Transmission Temperature Warning Light This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.

Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear for 3.6L engine, fourth
and fifth gears for 5.7L engine). The transmission will
automatically shift to Overdrive, if the following condi-
tions are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer to the “Note” under
“Torque Converter Clutch” in this section.
During cold temperature operation you may notice de-
layed upshifts, depending on engine and transmission
temperature. This feature improves the warm-up time of
the engine and transmission.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “TRANSMISSION
OVER TEMP” message may display, and the transmis-
sion may downshift out of Overdrive until the transmis-
sion cools down. After cool down, the transmission will
resume normal operation.
5
STARTING AND OPERATING 347

In high ambient temperatures with sustained high engine
speed and load, an upshift, followed shortly thereafter by a
downshift, may occur. The “TOW/HAUL Indicator Light”
will turn off. This is a normal part of the overheat protec-
tion strategy when operating in the TOW/HAUL mode.
Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the Transmission Limp Home
Mode will be engaged. In this mode, the transmission
will remain in the current gear (3.6L 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 en-
gine.
5. Move the shift lever to the desired gear range.
If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate normally. Only second gear (3.6L 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 transmission on your vehicle.
A clutch within the torque converter engages automati-
cally, at a calibrated speed, at light throttle. It engages at
higher speeds under heavier acceleration. This may re-
sult in a slightly different feeling or response during
normal operation in high gear. When the vehicle speed
5
STARTING AND OPERATING 349

drops below a calibrated speed, or during acceleration,
the clutch automatically and smoothly disengages.
NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally 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 demonstrate that the transmission
is able to shift into and out of Overdrive. For vehicles
with 5.7L engines (which have two Overdrive gears),
the transmission may not shift into the top Overdrive
gear (normal fifth gear) until the transmission fluid
and engine coolant are warm.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds after starting the
engine.
ALL-WHEEL DRIVE OPERATION
Single-Speed Operating Instructions/Precautions
(3.6L Engine) – If Equipped
This system contains a single-speed (HI range only)
transfer case, which provides convenient full-time all-
wheel drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
350 STARTING AND OPERATING

If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain forward motion
by turning the front wheels slowly. This may provide a
fresh “bite” into the surface and will usually provide
traction to complete the climb.
Traction Downhill
Shift the transmission into a low gear, and the transfer
case into LOW range. Let the vehicle go slowly down the
hill with all four wheels turning against engine compres-
sion drag. This will permit you to control the vehicle
speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it isalways 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, steering, 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 components, steering, and sus-
pension. Retighten 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.

Differential (BLD), 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 ESC system is in the “Partial Off” mode.
Refer to “Electronic Stability Control (ESC)” in this
section for more information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive thebenefit of the system, you must apply
continuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
BAS cannot prevent collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.

8. Lower the vehicle by turning the jack screw counter-
clockwise, and remove the jack and wheel blocks.
9. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. The correct
wheel nut tightness is 110 ft lbs (150 N·m). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.
10. Remove the small center cap and position the alumi-
num road wheel behind rear bumper with the “beauty
side” facing rearward.11. Insert the two long tubes on the plastic protective
plate in the lug holes of the road wheel. Push the end of
the winch’s cable, spring, steel sleeve and stamped cone
shape wheel plate though the road wheel and protective
plate.
