Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and side wall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, water, oil, or other fluid leaks. Also, if gasoline
fumes are present, the cause should be corrected imme-
diately.

Low Tire Pressure Telltale / TPMS Malfunction
Indicator
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat andcan lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver 's responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain
continuously illuminated. This sequence will continue

between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, safely bring the vehicle
to a complete stop and turn off the engine. DO NOT
operate the vehicle until the cause is corrected.
This gauge does not indicate the amount of oil in the
engine. The engine oil level must be checked under the
hood. Check the level often during severe usage.
Oil Pressure Warning Light
The red Oil Pressure Warning Light is located in
the Oil Pressure Gauge. It will turn on to indicate
low engine oil pressure. The light should turn on briefly
as a bulb check when the engine is first started. If the
light remains on or turns on while driving, safely bring
the vehicle to a complete stop and turn off the engine. DO
NOT operate the vehicle until the cause is corrected.NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked using
the procedure shown in section 7. (See page 198 for more
information.)
Fuel Gauge
This gauge shows the amount of fuel in the gas
tank. The reaction time of the gauge has been
slowed to avoid needle fluctuation during pe-
riods of high G force cornering.
Voltage Gauge
This gauge shows the electrical system voltage.
The normal operating voltage is from 12 to 14
volts with the engine running. If the pointer
remains at either the high or low ends of the
scale, the electrical system should be serviced.

130 STARTING AND OPERATING

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Over inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed either on
the face of the driver's door or on the driver's side ªBº
pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than themaximum loaded vehicle condition. These pressure con-
ditions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to

158 STARTING AND OPERATING

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 coolant performance, poor gas
mileage, and increased emissions.
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, checking, tears, cuts, abrasions,
and excessive swelling suggest deterioration of the rub-
ber.
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 degradation that could result in failure.Fuel System
High pressure fuel system hoses have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
Use only manufacturer specified hoses or their equiva-
lent in material and specification, in any fuel system
servicing. It is mandatory to replace all clamps that have
been loosened or removed during service.
224 MAINTAINING YOUR VEHICLE

VEHICLE STORAGE
We recommend that you follow these guidelines for
storing your vehicle for extended periods.
²Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than 2 months, add an anti-oxidant fuel stabilizer to
the fuel tank.
²Change the oil to remove any corrosive combustion
related acids in the crankcase.
²Check that the radiator coolant level of protection is to
at least -20ÉF (-29ÉC).
²Make sure that all tires are inflated to the optimum
pressure. (See page 158 for more information.)
²Wash and wax the vehicle to protect the finish.
²Store the vehicle in a dry, well-ventilated location.
²Move the wiper blades away from the windshield.
²Block the wheels. Do not apply the Parking Brake.
²Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
²For long-term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
²If the vehicle will be subjected to freezing tempera-
tures, either remove the battery and store it in a dry,
well ventilated area or connect a trickle charger (1.5
Amp) with automatic shutdown / overcharge protec-
tion to the battery. However, do not leave the trickle
charger hooked up to the battery without being
plugged in to a 110 volt AC outlet, as this will result in
further drain on the vehicle's battery. If the vehicle is
not going to be driven in the next 3 weeks, perform the
battery recharge procedure in the Service Manual.
238 MAINTAINING YOUR VEHICLE

At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery, and clean and tighten the terminals
as required.
²Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering, and transmission,
and add as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
NOTE:Also, inspect the exhaust system if you notice a
change in the sound of the exhaust system, or if the
exhaust fumes can be detected inside the vehicle.
²Inspect the brake hoses.
²Inspect the suspension components.
²Lubricate door hinges and check springs.
²Check the engine coolant level, hoses, and clamps.
²Check power steering fluid level.
