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, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to the Tire–
Safety Information Section in this manual.
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
374 STARTING AND OPERATING

•When 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.
•Safety 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.
•Vehicles 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
P for Park. Always, block or chockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
STARTING AND OPERATING 377

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “3” range
should be selected.
NOTE: Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive 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. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals.
NOTE: Check the automatic transmission fluid level
before towing.

Towing Tips — Electronic Speed Control (If
Equipped)

Don’t 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.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE (Flat towing with all four wheels on the
ground)
Recreational towing for this vehicle is not recommended.
NOTE: If the vehicle requires towing make sure all four
wheels are off the ground.
382 STARTING AND OPERATING

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in
neutral, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “H”, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, turn the engine off immediately, and call for
service.

•For convenience in checking the spare tire inflation,
stow with the valve stem toward the rear of the
vehicle.
•Using the jack handle, rotate the drive nut to the
right until the wheel is drawn into place against the
underside of the vehicle.
•Continue to rotate the nut until you hear the mecha-
nism click three times. It cannot be overtightened.
Push against the tire several times to be sure it is
securely in place.
13. Stow the jack and jack handle.
14. Check the tire pressure as soon as possible. Correct
pressure as required.
JUMP-STARTING PROCEDURE
WARNING!
•Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission cannot be
started this way. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from another
vehicle. This type of start can be dangerous if done improperly,
so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow battery
fluid to contact eyes, skin or clothing. Don’t lean over battery
when attaching clamps or allow the clamps to touch each other.
If acid splashes in eyes or on skin, flush contaminated area
immediately with large quantities of water.
•A battery generates hydrogen gas which is flammable and
explosive. Keep flame or spark away from the vent holes. Do
not use a booster battery or any other booster source with an
output that exceeds 12 volts.
•Take care to avoid the radiator cooling fan whenever the hood
is raised. It can start anytime the ignition switch is on. You can
be hurt by the fan.

Check the Battery Test Indicator (if equipped). If a light or
bright colored dot is visible in the indicator (if equipped),
DO NOT jump-start the battery.
If the indicator (if equipped) is dark or shows a green dot,
proceed as follows:
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach and
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in PARK and turn the
ignition switch to the OFF position for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads. 4. Connect one end of a jumper cable to the positive
terminal of the discharged battery. Connect the other end
of the same cable to the positive terminal of the booster
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
5. Connect the other cable, first to the negative terminal
of the booster battery and
then to the engine of the
vehicle with the discharged battery. Make sure you have
a good contact on the engine.
406 WHAT TO DO IN EMERGENCIES

WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 35 mph (55 km/h) when you are stuck. And
don’t let anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 35 mph (55 km/h).
TOWING A DISABLED VEHICLE
With Ignition Key
Your vehicle may be towed under the following condi-
tions: The gear selector must be in NEUTRAL, the
distance to be traveled must not exceed 100 miles (160
km), and the towing speed must not exceed 44 mph (72
km/h). Exceeding these towing limits may cause a trans-
mission geartrain failure. If the transmission is not op-
erative, or if the vehicle is to be towed more than 100
miles (160 km), the vehicle must be towed with the front
wheels off the ground.
