6000 RPM. This serves as a visual aid to shift before
reaching the red line. This warning will turn off when the
tachometer pointer falls below 5900 RPM.
Coolant Temperature Gauge
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temperatures when driving in hot weather, up
mountain grades, or in heavy stop and go
traffic. If the red Warning Light turns on while driving,
safely bring the vehicle to a stop, and turn off the engine.
DO NOT operate the vehicle until the cause is corrected.
Engine Temperature Warning Light
The red Engine Temperature Warning Light is
located in the Coolant Temperature Gauge. It will
turn on to warn of an overheated engine condi-
tion. If this light turns on while driving, safely bring the
vehicle to a stop and turn off the engine. DO NOT
operate the vehicle until the cause is corrected.
Oil Temperature Gauge
This gauge shows the oil temperature. The
gauge pointer will likely show higher tempera-
tures when driving in hot weather, up moun-
tain grades, or in heavy stop and go traffic. If
the red Warning Light remains on after the bulb check 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.
Oil Pressure Gauge
This gauge shows engine oil pressure when the
engine is running. The pressure will vary with
engine speed, oil viscosity, and engine tem-
perature. Oil pressures will be higher as the
engine is warming up. The normal operating pressure is
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.
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.
Charge System Light
The red Charge System Light is located in the
Voltage Gauge. It will turn on when there is a
charging system malfunction or a possible accessory
drive belt failure.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.

WARNING!
TIREFIT is not a permanent flat tire repair. Have the
tire inspected and repaired or replaced after using
TIREFIT. Do not exceed 55 mph (90 km/h) until
having the tire repaired or replaced. Failure to follow
this warning can result in injuries that are serious or
fatal to you, your passengers, and others around you.
F. After Securing TIREFIT Sealant in the Tire
1. Turn the Mode Select knob 4 to the Air
Mode position.
2. Uncoil the Black Air Pump Hose 6 and connect it to the
valve stem.
3. Check the pressure in the tire by reading the Pressure
Gauge 2.
•If the pressure is less than 19 psi (1.3 bar), the tire is
too badly damaged. Do not attempt to drive the
vehicle further. Call for assistance.
•If the pressure is equal to or greater than 19 psi
(1.3 bar), but less than the level indicated on the tire
pressure label, proceed to Step 4 of this procedure.
•If the pressure is at the level indicated on the tire
pressure label on the driver-side latch pillar, proceed
to Step 5 of this procedure.
4. Inflate the tire to the pressure indicated on the tire
pressure label on the driver-side latch pillar.
5. Disconnect the TIREFIT kit from the valve stem and
then reinstall the cap on the valve stem.
6. Place the TIREFIT kit in its proper storage area in the
vehicle.
WHAT TO DO IN EMERGENCIES 189

The best time to check the oil level is approximately five
minutes after a fully warmed engine is turned off or
before starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground also
will improve the accuracy of the oil level readings. Add
oil only when the level is below the SAFE mark.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Change Engine Oil
Road conditions and your kind of driving affect the
interval at which your oil should be changed. Check the
following list to see if any apply to you.
•Day or night temperatures are below 32°F (0°C)
•Stop and go driving
•Extensive engine idling
•Driving in dusty conditions
•Short trip driving of less than 10 miles (16.2 km)
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C)
NOTE:IfANYof these apply to you, then change your
engine oil every 3,000 miles (5 000 km) or three months,
whichever comes first, and follow “Maintenance Sched-
ule B.” Refer to Section 8 of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on “Maintenance Schedule A.
Refer to Section 8 of this manual.
NOTE:Under no circumstances should oil change in-
tervals exceed 6,000 miles (10 000 km) or 6 months,
whichever comes first.
204 MAINTAINING YOUR VEHICLE

VEHICLE STORAGE
We recommend that you follow these guidelines for
storing your vehicle for extended periods.
•Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than two months, add an anti-oxidant fuel stabilizer to
the fuel tank.
•Change the oil to remove any corrosive combustion
related acids in the crankcase.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Make sure that all tires are inflated to the optimum
pressure.
•Wash and wax the vehicle to protect the finish.
•Store the vehicle in a dry, well-ventilated location.
•Move the wiper blades away from the windshield.
•Block the wheels. Do not apply the parking brake.
•Cut 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.
•For 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.
•If 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
protection 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 three weeks, perform
the battery recharge procedure in the Service Manual.
234 MAINTAINING YOUR VEHICLE

At Each Stop for Fuel
•Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery, and clean and tighten the terminals
as required.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering, and transmission,
and add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect 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.
•Inspect the brake hoses.
•Inspect the suspension components.
•Lubricate door hinges and check springs.
•Check the engine coolant level, hoses, and clamps.
•Check power steering fluid level.
