gear (Overdrive). The transmission will automatically
shift from Drive to Overdrive, if the following conditions
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 temperatures,
the transmission may not shift into Overdrive and will automatically select the most desirable gear for opera-
tion at this temperature. Normal operation will re-
sume when the transmission fluid temperature has
risen to a suitable level. Refer to “Torque Converter
Clutch” in this section.
•If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
“Transmission Temperature Warning Light” may illu-
minate and the transmission may downshift out of
Overdrive until the transmission cools down. After
cool down, the transmission will resume normal
operation.
The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).

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.
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 differ-
ent 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 (usu-
ally after 1-3 miles [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 transmis-
sion is not shifting into Overdrive when cold. This is
normal. Pressing the TOW/HAUL switch, when the
transmission is sufficiently warm, will demonstrate
that the transmission is able to shift into, and out of
Overdrive.
•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 of shifting from
PARK into any other gear position.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, 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. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.

NOTE:Check the automatic transmission fluid level
before towing.
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.
Electronic Speed Control – If Equipped
Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can resume cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOWPLOW
Snow plows, winches, and other aftermarket equipment
should notbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
324 STARTING AND OPERATING
Page 326 of 450

WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Two-Wheel Drive Models
Recreational towing of two-wheel drive models is not
allowable. Towing the vehicle with the transmission in
NEUTRAL can cause severe transmission damage. Re-
moval of the driveshaft for towing is not recommended,
since this would allow fluid to drain from the
transmission.
Four-Wheel Drive Models
CAUTION!
•Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
•The transfer case must be shifted into NEUTRAL
for recreational towing. The NEUTRAL button is
located on the lower left hand corner of the trans-
fer case switch. Shifts into and out of transfer case
NEUTRAL can take place with the transfer case
switch in any mode position.
•Automatic transmissions must be placed in PARK
position for recreational towing.
•Failure to follow these procedures can cause se-
vere transmission and/or transfer case damage.
