ONBOARD DIAGNOSTIC SYSTEM — 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 Malfunction Indicator Light (MIL). 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 authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the
MAINTAINING YOUR VEHICLE 297

Trip Odometer button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of this vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if the vehicle was recentlyserviced, recently had a dead battery, or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, the vehicle may fail the test.
This vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if this vehicle’s OBD II system is ready, you must
do the following:
1. Insert the ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn the ignition key to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.

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.
•Inspect the brake hoses whenever the brake system is
serviced and at every engine oil change. Inspect hy-
draulic brake hoses for surface cracking, scuffing, or
worn spots. If there is any evidence of cracking,
scuffing, or worn spots, the hose should be replaced
immediately. Eventual deterioration of the hose can
take place resulting in a possibility of a burst failure.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the brake
pads wear. However, low fluid level may be caused by a
leak and a checkup may be needed.
MAINTAINING YOUR VEHICLE 321

•Change your engine oil more often if you drive your
vehicle for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 mi (10 000 km) or six months, whichever
comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If this
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Oil Change
Required” under “Electronic Vehicle Information Center
(EVIC)” in Section 4.
At Each Stop for Fuel
•Check the engine oil level. Refer to “Engine Oil” under
“Maintenance Procedures” in Section 7.
•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 coolant reservoir and brake
master cylinder, and add as needed.
•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
