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 mode (if equipped), or a lower gear range,
should be selected.
NOTE:Using the TOW/HAUL mode (if equipped) or
selecting a lower gear range (using the Electronic Range
Select (ERS) feature) while operating the vehicle under
heavy operating conditions, will improve performance
and extend transmission life by reducing excessive shift-
ing and heat buildup. This action will also provide better
engine braking. The transmission fluid and filter should be changed if
you REGULARLY tow a trailer for more than 45 minutes
of continuous operation. Refer to “Maintenance Sched-
ule” for the proper maintenance intervals.
NOTE:
Check the transmission fluid level before towing
(5.7L engine).
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 get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

STARTING AND OPERATING 337

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.
SNOW PLOW
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.
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.)
Towing – Two-Wheel Drive Models
Recreational towing is allowed ONLY if the driveshaft
is removed. Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
338 STARTING AND OPERATING

WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.
The parking brake must be firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remain engaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange
orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.
Towing — Quadra-Trac I (Single-Speed Transfer
Case) Four-Wheel Drive Models
Recreational towing is not allowed. This model does not
have a NEUTRAL position in the transfer case.
Towing — Quadra–Trac II /Quadra–DriveII
Four-Wheel Drive Models
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
NOTE: The transfer case must be in the NEUTRAL
position, and the transmission must be in the PARK
position for recreational towing.5
STARTING AND OPERATING 339

WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
Shifting Into NEUTRAL
Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL before recre-
ational towing to prevent damage to internal parts.
1. Press the brake pedal.
2. Turn the ignition switch to the ON position, engine off.
3. Shift the transmission into NEUTRAL.
4. Shift the transfer case into NEUTRAL.
Hold down the NEUTRAL “pin” switch (with a pen, etc.)
for four seconds until the LED lamp by the switch starts
to blink, indicating shift in progress. The lamp will stop
blinking (stay on solid) when the NEUTRAL shift is
complete. A “4WD SYSTEM IN NEUTRAL” message will
display on the EVIC (Electronic Vehicle Information
340 STARTING AND OPERATING

Center). Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information.5. Start the engine.
6. Shift the transmission into DRIVE.
7. Release the brake pedal and ensure that there is no
vehicle movement.
8. Turn the engine off.
9. Shift the transmission into PARK.
10. Turn the ignition switch to the OFF position, and
remove key fob.
11. Apply the parking brake.
12. Attach the vehicle to the tow vehicle with tow bar.
13. Release the parking brake.

STARTING AND OPERATING 341

CAUTION!
Transmission damage may occur if the transmission
is shifted into PARK with the transfer case in NEU-
TRAL and the engine running. With the transfer case
in NEUTRAL ensure that the engine is OFF prior to
shifting the transmission into PARK (refer to steps 7
and 8 above).
Shifting Out Of NEUTRAL
Use the following procedure to prepare your vehicle for
normal usage.
1. Press the brake pedal.
2. Turn the ignition switch to the ON position, engine off.
3. Shift the transmission into NEUTRAL.
4. Shift the transfer case out of NEUTRAL.Hold down the NEUTRAL “pin” switch (with a pen, etc.)
for four seconds until the LED lamp by the switch starts
to blink, indicating shift in progress. The lamp will stop
blinking (go out) when shift is complete. The “4WD
SYSTEM IN NEUTRAL” message will no longer be
displayed on the EVIC (Electronic Vehicle Information
Center). Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information.
