Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle, for
all loading conditions.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier suspension compo-
nents do not necessarily increase the vehicle’s GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight. Store heavier items down low and be sure you
distribute their weight as evenly as possible. Stow all
loose items securely before driving. Improper weight
distribution can have an adverse effect on the way your
vehicle steers and handles, and the way the brakes
operate.

Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the vehicle. These kind of
hitches are the most popular on the market today and
they’re commonly used to tow small- and medium-sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age through spring (load) bars. They are typically used
for heavier loads, to distribute trailer tongue weight to
the tow vehicle’s front axle and the trailer axle(s). When
used in accordance with the manufacturers’ directions, it
provides for a more level ride, offering more consistent
steering and brake control, thereby enhancing towing
safety. The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight distributing (loadequalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on Vehicle
and Trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
Trailer Hitch Classification
Your vehicle may be factory equipped for safe towing of
trailers weighing over 2,000 lbs (907 kg) with the optional
Trailer Tow Prep Package. See your authorized dealer for
package content.
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class can
tow and should be used to assist you in selecting the
correct trailer hitch for your intended towing condition.
Refer to the Trailer Towing Weights (Maximum Trailer
Weight Ratings) chart for the maximum GTW towable for
your given drivetrain.
318 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
PARK. Always block orchockthe 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).
322 STARTING AND OPERATING

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
“Tires – General Information” in this section for proper
tire inflation procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires–General Information” in
this section for the proper inspection procedure.
When replacing tires, refer to “Tires–General Informa-
tion” in this section for proper tire replacement proce-
dures. Replacing tires with a higher load carrying
capacity will not increase the vehicle’s GVWR and
GAWR limits.
Towing Requirements — Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
STARTING AND OPERATING 323

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a 4- and 7-pin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

rized dealer to correct this condition.
1. When boosting from a battery in another vehicle, park
that vehicle within booster cable reach but without
letting the vehicles touch. Set the parking brake, place the
automatic transmission in PARK (the manual transmis-
sion in NEUTRAL) and turn the ignition to OFF for both
vehicles.
2. Turn off the heater, radio and all unnecessary electrical
loads.
3. Using the two finger screws on the cover, remove the
air intake duct covering the battery.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the jumper cable to the positive terminal of the dis-
charged battery.WARNING!
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don’t lean over the battery when attaching the
clamps or allow the clamps to touch each other. If
acid splashes in your eyes or on your skin, flush
the contaminated area immediately with large
quantities of water.
•A battery generates hydrogen gas which is flam-
mable 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.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the negative terminal of
the discharged battery. Make sure you have a good
contact.

All Transaxles
If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACC position. Make certain the trans-
mission remains in NEUTRAL.
CAUTION!
•If the vehicle being towed requires steering, the
ignition switch must be in the ACC position, not
in the LOCK position.
•Do not attempt to use sling type equipment when
towing. When securing the vehicle to a flat bed
truck, do not attach to front or rear suspension
components. Damage to your vehicle may result
from improper towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. A dolly should be
used under the front wheels if the rear wheels are raised.
Proper towing equipment is necessary to prevent dam-
age to the vehicle.
Battery power is required to release the brake/
transmission interlock system. There is a removable plug
in the right side of the shift lever housing that allows you
to insert your finger to override the system. The ignition
key must be in the ON position to use the override lever.
