Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
third, and fourth gears, direct fifth gear and overdrive
sixth gear. The DRIVE position provides optimum driv-
ing characteristics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick® shift
control (refer to “AutoStick® (Six-Speed Automatic
Transmission)” in this section for further information) to
select a lower gear. Under these conditions, using a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will modify the
transmission shift schedule and expand the range of
torque converter clutch engagement. This is done to
prevent transmission damage due to overheating. If the
transmission becomes extremely hot, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmis-
sion cools down.

STARTING AND OPERATING 329

If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (sixth gear). The transmission will
automatically shift into Overdrive if the following con-
ditions are present:
•The shift lever is in the DRIVE position.
•The transmission fluid has reached an adequate tem-
perature.
•The engine coolant has reached an adequate tempera-
ture.
•The vehicle speed is sufficiently high.
•The driver is not heavily pressing the accelerator.
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 calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE:Engagement of the torque converter clutch is
inhibited at very cold temperatures. 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. The torque
converter clutch will function normally once the trans-
mission is sufficiently warm.

FOUR-WHEEL DRIVE OPERATION —
IF EQUIPPED
This feature provides full time, on-demand, four–wheel
drive (4WD).
Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose
traction surfaces, activate the “4WD LOCK” switch by
pulling up once and releasing. This locks the center
coupling allowing more torque to be sent to the rear
wheels. The “4WD Indicator Light” will come on in the
cluster. This can be done on the fly, at any vehicle speed.
To deactivate, simply pull on the switch one more time.
The “4WD Indicator Light” will then go out.
NOTE:Refer to “Electronic Brake Control System/
Electronic Stability Control (ESC)” in “Starting and Op-
erating” for further information.

CAUTION!
Muddy waters can reduce the cooling system effec-
tiveness by depositing debris onto the radiator.
After Driving Off-Road
Off-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, 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.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, 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

WARNING!
The Anti-Lock Brake System (ABS) contains sophis-
ticated electronic equipment that may be susceptible
to interference caused by improperly installed or
high output radio transmitting equipment. This in-
terference can cause possible loss of Anti-Lock brak-
ing capability. Installation of such equipment should
be performed by qualified professionals.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
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 ESC are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Control (ESC)” in this section of this
manual.
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 the

seconds when the vehicle is stopped and the engine is
running. After five seconds, the#ESC OFF Indicator
Light#will illuminate and the “ESC OFF” message will
appear in the odometer. Press and release the Trip
Odometer button located on the instrument cluster to
clear this message.
In this mode, ESC and TCS, except for the “limited slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 35 mph (56 km/h). At
35 mph (56 km/h) the system returns to “Partial Off”
mode, as described above. TCS remains off. When the
vehicle speed drops below 30 mph (48 km/h) the ESC
system shuts off. ESC is deactivated at low vehicle speeds
so that it will not interfere with off-road driving however,
ESC function returns to provide the stability feature at
speeds above 35 mph (56 km/h). The#ESC OFF Indicator
Light#will always be illuminated when ESC is off.
To turn ESC on again, momentarily press the “ESC Off”
switch. This will restore the “ESC On” mode of operation.
NOTE:The “ESC OFF” message will display and an
audible chime will sound when the shift lever is placed
into the PARK position from any other position, and then
moved out of the PARK position. This will occur even if
the message was previously cleared.
WARNING!
With the ESC in the%Full Off%mode, the engine
torque reduction and stability features are disabled.
In an emergency evasive maneuver, the ESC system
will not engage to assist in maintaining stability.
“ESC Off” mode is intended for off-highway or
off-road use only.

CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the pointer rises to the H (red) mark, the
instrument cluster will sound a chime. When safe,
pull over and stop the vehicle with the engine at idle.
Turn off the air conditioning and wait until the pointer
drops back into the normal range. If the pointer
remains on the H (red) mark for more than a minute,
turn the engine off immediately and call for service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.
