•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. Max loading as defined on the “Tire and Loading
Information” placard.
2. GTW3. 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
“Tires–General Information” in this section for infor-
mation on tire pressures and for proper tire inflation
procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing up the trailer in an area located away from
heavy traffic.
Towing Tips — Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, 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.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the automatic
transmission fluid and filter according to the interval
specified for “police, taxi, fleet, or frequent trailer tow-
ing” in the Maintenance Schedule.
Towing Tips — 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.
Towing Tips — Autostick(If Equipped)
By using the Autostickmodes and selecting a specific
gear range, frequent shifting can be avoided. The
highest gear range should be selected that allows for
adequate performance. For example, choose “4” if the
desired speed can be maintained. Choose “3” or “2” if
needed to maintain the desired speed.

6. Block the front and rear of the
wheel diagonally opposite of the jack-
ing position. For example, if changing
the right front tire, block the left rear
wheel.
NOTE:Passengers should not remain in the vehicle
when the vehicle is being jacked.
Jacking and Changing a Tire
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
(Continued)
WARNING! (Continued)
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
•Never start or run the engine with the vehicle on a
jack.
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.

JUMP-STARTING PROCEDURES
WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be hurt by the fan.
•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 converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged 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.
(Continued)
WARNING! (Continued)
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin, or cloth-
ing. 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 contami-
nated 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.
•The battery in this vehicle has a vent hose that
should not be disconnected and should only be
replaced with a battery of the same type (vented).

Towing This Vehicle Behind Another Vehicle (Flat
Towing With All Four Wheels On The Ground)
Flat towing of vehicles equipped with an automatic
transmission, is only permitted within the following
limitations.
With The Ignition Key
Your vehicle may be towed under the following condi-
tions: The shift lever must be in NEUTRAL, the distance
to be traveled must not exceed 30 miles (48 km), and the
towing speed must not exceed 30 mph (48 km/h).
Exceeding these towing limits may cause a transmission
gear failure. If the transmission is not operative or if the
vehicle is to be towed more than 30 miles (48 km), the
vehicle must be transported using a flatbed truck.
CAUTION!
•Do not attempt to tow this vehicle from the front
with sling type towing equipment. Damage to the
front fascia will result.
•If the transmission is not operative or if the
vehicle is to be towed more than 30 miles (48 km),
then the only approved method of towing is with
a flatbed truck. Damage to the transmission may
result.
•Do not tow the vehicle from the rear. Damage to
the rear sheet metal and fascia will occur.
•Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
mission may result.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the

WARNING!
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
•Use of a brake fluid that may have a lower initial
boiling point, or is unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
CAUTION!
Do not allow petroleum-based fluid to contaminate
the brake fluid. Seal damage may result.
Automatic Transmission
Fluid Level Check
Regular automatic transmission fluid level checks are not
required. For this reason, the dipstick is omitted.
If you notice fluid loss or gear shift malfunction, have
your authorized dealer check the transmission fluid level.
CAUTION!
•Using a transmission fluid other than the manu-
facturer’s recommended fluid may cause deterio-
ration in transmission shift quality and/or torque
converter shudder. Using a transmission fluid
other than that recommended by the manufacturer
will result in more frequent fluid and filter
changes. Refer to “Fluids, Lubricants, and Genu-
ine Parts” in this section for the correct fluid type.
