ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located 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.
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.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling. When the fuel nozzle
ªclicksº or shuts off, the fuel tank is full.
NOTE:
²Tighten 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 in the instrument cluster
will turn on. Make sure that the gas cap is tightened
each time the vehicle is refueled.
²When the fuel nozzle ªclicksº or shuts off, the fuel
tank is full.
240 STARTING AND OPERATING

Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle's
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.A loaded vehicle is shown in the illustration. Note that
neither the GVWR or the GAWR capacities have been
exceeded.
STARTING AND OPERATING 243

location.Do not raise the vehicle until you are sure the
jack is securely engaged. Never jack up the vehicle
using any suspension components.
6. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
7. Remove the wheel lug nuts, then pull the wheel off the
hub.
8. Install the spare wheel. Then install the wheel lug nuts
with the cone shaped end of the nut toward the wheel.
Lightly tighten the nuts. To avoid the risk of forcing the
vehicle off the jack, do not tighten the lug nuts fully until
the vehicle has been lowered.
9. Lower the vehicle by turning the jack screw to the left.
10. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. Correct
wheel nut tightness is 130 N´m (95 ft. lbs). If in doubt
about the correct tightness, have them checked with a
torque wrench by your dealer or at a service station.
11. Lower the jack to its fully closed position.
256 WHAT TO DO IN EMERGENCIES

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.
12. Secure the flat or spare tire as follows:
²The center cap of a cast aluminum wheel must be
removed prior to flat tire stowage. Store the center
cap inside the glove box or other storage compart-
ment.
²Turn the wheel so that the valve-stem is down. Slide
the wheel retainer through the center of the wheel
and position it properly across the wheel opening.
²For convenience in checking the spare tire inflation,
stow with the valve-stem toward the rear of the
vehicle.
²Using the jack-handle, rotate the drive nut to the
right until the wheel is drawn into place against the
underside of the vehicle.
²Continue to rotate the nut until you hear the mecha-
nism click three times. It cannot be overtightened.
Push against the tire several times to be sure it is
securely in place.
13. Stow jack and handle.
14. Check the tire pressure as soon as possible. Correct
pressure as required.
NOTE:When reinstalling the wheel center cap, insure
that the valve stem symbol on the back of the cap is
pointed toward the wheel valve stem. Install the center
cap using hand pressure only. Do not use a hammer.
WHAT TO DO IN EMERGENCIES 257

²If frequent coolant additions are required, the cooling
system should be pressure tested for leaks.
²Maintain coolant concentration at 50% ethylene glycol
antifreeze (minimum) in water for proper corrosion
protection of your engine which contains aluminum
components.
²Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
²Keep the front of the radiator and the front of the A/C
condenser clean.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.
²Increasing engine speed at idle does not reduce cool-
ant temperature! Put transmission in NEUTRAL and
let engine idle at normal engine idle speed.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
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.

Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Schedules.
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.
Brake And Power Steering Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
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.
NOTE:Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before a hose is
replaced based on leakage.
