sulfur to determine if the problem is fuel related prior to
returning your vehicle to an authorized dealer for ser-
vice.
CAUTION!
If the Check Engine or Service Engine Soon light is
flashing, immediate service is required; see onboard
diagnostics system section.
Materials Added To Fuel
All gasolines sold in the United States are required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door. If the gas cap is
lost or damaged, be sure the replacement cap is for use
with this vehicle.
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.
186 STARTING AND OPERATING

WARNING!
²Remove the fuel tank filler tube cap (gas cap)
slowly to prevent fuel spray from the filler neck
which may cause injury.
²The 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.
²Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
²Never add fuel to the vehicle when the engine is
running.
Fuel Tank Filler Tube
NOTE:
On some models, the fuel tank filler tube has a
restricting door about 2 inches (50 mm) down from the
opening. If fuel is poured from a portable container, the
container 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:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
NOTE:Tighten the gas cap until you hear a ªclickingº
sound. This is an indication that the gas cap is properly
tightened.
The Check Engine light will come on if the gas cap is
not properly secured. Make sure that the gas cap is
tightened each time the vehicle is refueled.

WARNING!
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.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The 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.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor orsome light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²When pulling a heavy load or driving a fully loaded
vehicle when the humidity is low and the temperature
is high, use a premium unleaded fuel to help prevent
spark knock. If spark knock persists, lighten the load,
or engine piston damage may result.
²The use of fuel additives which are now being sold as
octane enhancers is 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 is 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.
188 STARTING AND OPERATING

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
²Do 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.
²Guard 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.
²Keep the liftgate closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.
CATALYTIC CONVERTER
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
converter as an emission control device. Under normal
operating conditions, the catalytic converter will not
require maintenance. However, you must keep the en-
gine maintained to assure proper operation and prevent
possible damage.
NOTE:Intentional tampering with emissions control
systems result in civil penalties being assessed against
you.
STARTING AND OPERATING 189

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
As with any vehicle do not park or operate this vehicle in
areas where combustible materials such as grass or leaves
can contact a hot exhaust system.
A scorching odor may appear if you continue to run a
malfunctioning engine. The odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Service, including a tune-up to
manufacturer's specifications should be obtained imme-
diately.To minimize the possibility of catalytic converter dam-
age:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing.
²Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
²Do not allow vehicle to run out of fuel.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
190 STARTING AND OPERATING

Wheel9style trailer, this range of loading on the9King
Pin9should be between 15% and 25%.) Loads balanced
over the wheels or biased toward9heavier in the rear9
can cause the trailer to sway severely side to side
which will cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
²Donotinterconnect the hydraulic brake system of
your vehicle with that of the trailer. This could cause
inadequate braking and possible personal injury.
²Trailer brakes are recommended for trailers over 1,000
lbs. (454 kg) and required for trailers in excess of 2,000
lbs. (907 kg).
²Use an approved trailer harness and connector. If a
hitch is ordered, the proper wiring will be provided.
²When 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.
²Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
cannot be fully secured, dynamic load shifts can occur
that may be difficult for the driver to control.
²All trailer hitches should be professionally installed on
your vehicle.
²Safety chains must always be used between your
vehicle and trailer.
²Connect trailer lighting and brakes using factory har-
nesses only. Do not cut or splice any wiring to the
brake circuits.
Trailer and Tongue Weight
Gross Trailer Weight (GTW) means the weight of the
trailer plus the weight of all cargo and equipment loaded
on the trailer when in actual underway towing condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight
of the trailer must be supported by the scale.
Tongue Weight is the weight placed on the vehicle's
trailer hitch by the trailer. Always load a trailer with 60%

as a percentage of total trailer weight.)
4.GAWR ratings
NOTE:
Towing a trailer equipped with more than the
standard lighting (turn, tail, stop and backup lights) may
cause an abnormally high electrical current draw through
the headlight switch, causing the switch to fail. To
prevent a recurring switch failure install a trailer tow
wiring harness overlay kit with relay to bypass headlight
switch (available from your dealer).

Cooling System TipsÐTrailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions:
²City DrivingÐWhen stopped for short periods of
time, put transmission in neutral and increase engine
idle speed.
²Highway DrivingÐReduce your speed.
²Air ConditioningÐTurn off temporarily.
See Cooling System Operating information in the Main-
tenance section of this manual for more information.
To reduce potential for automatic transmission overheat-
ing, turn the Overdrive OFF when driving in hilly areas
or shift the transmission to Drive position 2 on more
severe grades. Move the shift lever to the next lower
position to eliminate excessive transmission shifting. This
action will also reduce the possibility of transmission
overheating and provide better engine braking.
NOTE:If your vehicle has an automatic transmission
and you tow a trailer frequently follow Maintenance
Schedule ªBº.
