Refer to local laws for maximum trailer towing speeds.
NOTE: The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo (ie.
the GVWR), and the GVWR should never exceed the
weight referenced on the Tire and Loading Information
placard. Refer to “Tire Safety Information” in “Starting
and Operating” for further information.
Trailer And Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to sway severelyside to side
which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer collisions.
532 STARTING AND OPERATING

CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
WARNING!
Improper towing can lead to a collision. 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 a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to the brakes, axle, engine, transmission, steer-
ing, suspension, chassis structure or tires.

534 STARTING AND OPERATING

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustration.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 first gear to avoid excessive clutch
slippage.
Automatic Transmission – If Equipped
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, use
the Electronic Range Select (ERS) shift control to select a
lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy loading conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
Four-Pin Connector
1 — Female Pins 4 — Park
2 — Male Pin 5 — Left Stop/Turn
3 — Ground 6 — Right Stop/Turn
538 STARTING AND OPERATING

If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified forpolice, taxi, fleet,
or frequent trailer towing. Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
NOTE: Check the automatic transmission fluid level
before towing.
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.
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.

STARTING AND OPERATING 539

Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive-
shafts 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.
CAUTION!
It is necessary to follow these steps to be certain that the
transfer case is fully in NEUTRAL (N) before recre-
ational towing to prevent damage to internal parts.
1. Bring the vehicle to a complete stop.
2. Press and hold the brake pedal.
3. Shift the automatic transmission into NEUTRAL ordepress the clutch pedal on a manual transmission.
4. Turn the engine OFF.
5. Shift the transfer case lever into NEUTRAL (N).
6. Start the engine.
7. Shift the transmission into REVERSE.
542 STARTING AND OPERATING

8. Release the brake pedal (and clutch pedal on manualtransmissions) for five seconds and ensure that there is
no vehicle movement.
9. Repeat Steps 7 and 8 with automatic transmission in DRIVE or manual transmission in first gear.
10. Turn the engine OFF.
11. Firmly apply the parking brake.
12. Shift the transmission into PARK or place manual transmission in gear (NOT in Neutral).CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL (N) and the engine running. With the
transfer case in NEUTRAL (N) ensure that the engine
is OFF before shifting the transmission into PARK.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.

STARTING AND OPERATING 543

Shifting Out of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Turn the ignition switch to the LOCK/OFF position.
4. Turn the ignition switch to the ON/RUN position, but do not start the engine.
5. Press and hold the brake pedal.
6. Shift the transmission into NEUTRAL.
7. Shift the transfer case lever to the desired position. NOTE:
When shifting the transfer case out of NEUTRAL
(N), turning the engine OFF may be required to avoid
gear clash.
8. Shift the automatic transmission into PARK, or place manual transmission in Neutral.
9. Release the brake pedal.
10. Disconnect vehicle from the tow vehicle.
11. Start the engine.
12. Press and hold the brake pedal.
13. Release the parking brake.
14. Shift the transmission into gear, release the brake pedal (and clutch pedal on manual transmissions),
and check that the vehicle operates normally.
