Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cautions
and Warnings before doing so.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stopping
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.
CAUTION!
• Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to

STARTING AND OPERATING 215

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 emission 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 Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check fuel cap” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
328 MAINTAINING YOUR VEHICLE

“Electronic Vehicle Information Center (EVIC)” in ”Un-
derstanding Your Instrument Panel” for further informa-
tion. Tighten the gas cap until aclickingsound is heard.
This is an indication that the gas cap is properly tight-
ened.
Push the odometer reset button to turn the message off. If
the problem persists, the message will appear the next
time the vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the system
will turn on the MIL. Resolving the problem will turn the
MIL light off.EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your 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 may notbe ready if your vehicle was recently
serviced, 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, your vehicle may fail the test.

MAINTAINING YOUR VEHICLE 329

Your vehicle has a simple ignition actuated test, which
you can use prior to going to the test station. To check if
your vehicle’s OBD II system is ready, you must do the
following:
1. Cycle the ignition switch to the ON position, but donot crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction Indicator Light
(MIL) symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF the ignition or start the engine. This means that your
vehicle’s OBD II system is
not readyand you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off
position or start the engine. This means that your
vehicle’s OBD II system is readyand you can proceed
to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
330 MAINTAINING YOUR VEHICLE

•Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns
on.
• Check the fluid levels of the coolant reservoir and
brake master cylinder, fill as needed.
• Check function of all interior and exterior lights.
Required Maintenance Intervals
Refer to the maintenance schedules on the following
page for the required maintenance intervals.At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter
• Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required
• Inspect brake pads, shoes, rotors, drums, hoses,
lines and park brake
• Inspect engine cooling system protection and
hoses
• Inspect exhaust system
• Inspect engine air cleaner if using in dusty or
off-road conditions 8
