The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully depressed at
vehicle speeds above approximately 35 mph (56 km/h).
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, 5th gear (if equipped) is
disabled and 2-3 and 3-4 shift patterns are modified.
Shifts into OVERDRIVE (4th gear) are allowed during
steady cruise (for improved fuel economy) and automatic
closed-throttle downshifts to 3rd gear (for improved
braking) will occur during steady braking.
The TOW/HAUL light will illuminate in the instrument
cluster to indicate when the switch has been activated.
Pressing the switch a second time restores normal opera-
tion. If the TOW/HAUL mode is desired, the button
must be pressed each time the engine is started.

Torque Converter Clutch
A feature designed to improve fuel economy is included
in all automatic transmissions. A clutch within the torque
converter engages automatically at a calibrated 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 calibrated speed, or
during acceleration, the clutch automatically and
smoothly disengages. The feature is operational in
OVERDRIVE and in DRIVE.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
(usually after 1-3 mi [1.6 - 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. Press-
ing the TOW/HAUL button, when the transmission is
sufficiently warm, will demonstrate that the transmissionis able to shift into, and out of, Overdrive. For vehicles
with 4.7L or 5.7L engines (which have two Overdrive
gears), the transmission may not shift into 5th gear until
the transmission fluid and engine coolant are warm.
NOTE:If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission 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 converter
will refill within five seconds of shifting from PARK into
any other gear position.

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

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
²When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
PARK. With a manual transmission, shift the transmis-
sion into REVERSE. And with 4-wheel drive vehicles,
make sure the transfer case is not in NEUTRAL.
Always, block or9chock9the trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer so that the following four
ratings are not exceeded:

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.If using a manual transmission vehicle for trailer towing,
all starts must be in 1stT gear to avoid excessive clutch
slippage.
Towing Tips Ð Automatic Transmission
The ªDº range can be selected when towing. However, if
frequent shifting occurs while in this range, the TOW/
HAUL feature should be selected.
NOTE:Using the TOW/HAUL feature while operating
the vehicle under heavy operating conditions will im-
prove performance and extend transmission life by re-
ducing excessive shifting and heat build up. This action
will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. For transmission
fluid change intervals, refer to ªMaintenance Scheduleº
in section 8.

NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips Ð Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the TOW/HAUL feature ON when driving in
hilly areas or shift the transmission to Drive position 2 on
more severe grades.
Towing Tips Ð Electronic Speed Control (If
Equipped)
þ
Don't use in hilly terrain or with heavy loads.
þWhen using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can resume cruising speed.
þUse speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
þCity Driving
When stopped for short periods of time, put transmission
in NEUTRAL and increase engine idle speed.
þHighway Driving
Reduce speed.
þAir Conditioning
Turn off temporarily.
þrefer to ªCooling System Operatingº under ªMainte-
nance Proceduresº in section 8.

Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the shift
lever in PARK (automatic transmission). On 4-wheel
drive vehicles, shift the transfer case to the ª4Lº position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
²Turn on the hazard warning flasher.
²Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
²Passengers should not remain in the vehicle when the
vehicle is being jacked.
