Fuel System Cautions
CAUTION!Follow these guidelines to maintain your vehicle's
performance:
² The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system, and could result
in loss of warranty coverage.
² An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance. ² The use of fuel additives which are now being sold as
octane enhancers are not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer and may not be
covered under the New Vehicle Warranty.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning: STARTING AND OPERATING 269
5

² Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
² Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
² Keep the liftgate closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle. ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door on the left side
of the vehicle. If the gas cap is lost or damaged, be sure
the replacement cap is for use with this vehicle.270 STARTING AND OPERATING

CAUTION!Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
NOTE: The driver's side sliding door cannot be opened
while the fuel door is open. This feature operates only
when the sliding door is fully closed prior to opening the
fuel door.
The fuel tank filler tube, on vehicles equipped with a
catalytic converter, has a restricting door about 50 mm (2
inches) inside the opening. If using a portable fuel
container, it should have a flexible nozzle long enough to
force open the restricting door. CAUTION!To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
NOTE:
² Tighten the gas cap until you hear a ªclickingº sound.
This is an indication that the gas cap is properly
tightened. If the gas cap is not secured properly the
Malfunction Indicator Light will turn on. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
² When the fuel nozzle ªclicksº or shuts off, the fuel
tank is full. STARTING AND OPERATING 271
5

WARNING!² Remove the fuel tank filler tube cap (gas cap) slowly
to prevent fuel spray from the filler neck which may
cause injury.
² The volatility of some gasolines may cause a buildup
of pressure in the fuel tank that may increase while
you drive. This pressure can result in a spray of
gasoline and/or vapors when the cap is removed
from a hot vehicle. Removing the cap slowly allows
the pressure to vent and prevents fuel spray.
² Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank
filled.
² Never add fuel to the vehicle when the engine is
running.
² A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling. VEHICLE LOADING
The load carrying capacity of your vehicle is shown in the
charts that follow. This information should be used for
passenger and luggage loading as indicated.
If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a certification label attached to the
driver's door pillar.
The label contains the following information:
² Name of manufacturer
² Month and year of manufacture
² Gross Vehicle Weight Rating (GVWR)
² Gross Axle Weight Rating (GAWR) front
² Gross Axle Weight Rating (GAWR) rear272 STARTING AND OPERATING

JUMP-STARTING PROCEDURES IF BATTERY IS
LOW
WARNING!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. WARNING!² Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the en-
gine 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.
² 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.
² 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.288 WHAT TO DO IN EMERGENCIES

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 emis-
sion 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.300 MAINTAINING YOUR VEHICLE
