²Name of manufacturer
²Month and year of manufacture
²Gross Vehicle Weight Rating (GVWR)
²Gross Axle Weight Rating (GAWR) front
²Gross Axle Weight Rating (GAWR) rear
²Vehicle Identification Number (VIN)
²Type of Vehicle
²Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the
Vehicle Identification Number (VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.

correct tightness of each lug nut is 100 ft/lb. (135 N. m).
If in doubt about the correct tightness, have them
checked with a torque wrench by your dealer or at a
service station.
7. For vehicles equipped with center caps, install the
center cap by hand. Do not use a hammer or excessive
force to install the center cap.
8. Stow the jack, tools, and spare tire. Make sure the base
of the jack faces the rear of the vehicle before tightening
down the fastener.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
JUMP-STARTING PROCEDURES
WARNING!
²Take 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.
²Do 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 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.
²Battery 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.
²A battery generates hydrogen gas, which is flammable and explo-
sive. Keep flame or spark away from the vent holes.
²Do not use a booster battery or any other booster source with an
output that exceeds 12 volts.
²The 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).

ONBOARD DIAGNOSTIC SYSTEM Ð 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 ªMalfunction Indicator Light.º 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 dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emission
control system. It could also affect fuel economy and
driveability. The vehicle must be serviced before any
emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur. Im-
mediate 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
ªCheck Gascapº message will display in the Electronic
Vehicle Information Center (EVIC) Ð if equipped. If this
occurs, tighten the fuel filler cap properly and press the

odometer reset button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Light)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
388 MAINTAINING YOUR VEHICLE

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
Fuel System
The Electronic Fuel Injection high-pressure fuel system's
hoses and quick connect fittings have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
You are urged to use only the manufacture specified
hoses with quick connect fittings, or their equivalent in
material and specification, in any fuel system servicing. It
is mandatory to replace any damaged hoses or quick
connect fittings that have been removed during service.Care should be taken in installing quick connect fittings
to insure they are properly installed and fully connected.
See your authorized dealer for service.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the ªMainte-
nance Scheduleº in Section 8 of this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
