ONBOARD DIAGNOSTIC SYSTEM Ð 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!
²Prolonged 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.
²If 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
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A loose fuel filler cap message
will be displayed in the instrument cluster. Tighten the
gas cap until a9clicking9sound is heard. This is an
indication that the gas cap is properly tightened. Press
the odometer RESET button to turn the message off. If the

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer's specifications, should be ob-
tained immediately.To minimize the possibility of catalyst damage:²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.

CAUTION!
Do not allow a petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.
Automatic Transmission
Fluid Level Check
NOTE:If equipped with a dipstick, use the following
procedure. If your vehicle has a capped dipstick, it is
sealed and should not be tampered with. Your authorized
dealer has the proper tools to ensure that the fluid level
is set properly.
Check the fluid level while the transmission is at normal
operating temperature 180ÉF (82ÉC). This occurs after at
least 15 miles (24 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.To check the automatic transmission fluid level properly,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake
pedal.
4. Place the shift lever momentarily in each gear position
ending with the lever in PARK.
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the ªHOTº
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that solid coating of oil is seen on
both sides of the dipstick. If the fluid is low, add as
406 MAINTAINING YOUR VEHICLE

required into the dipstick tube.Do not overfill.After
adding any quantity of oil through the oil fill tube, wait
a minimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two ªCOLDº (lower) holes on the dipstick
with the fluid at approximately 70ÉF (21ÉC) (room tem-
perature). If the fluid level is correctly established at
room temperature, it should be between the ªHOTº
(upper) reference holes when the transmission reaches
180ÉF ( 82ÉC). Remember it is best to check the level at the
normal operating temperature.CAUTION!
Be aware that if the fluid temperature is below 50ÉF
(10ÉC) it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.

Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer 's recommended transmis-
sion fluid; for correct fluid type, refer to ªAutomatic
Transmissionº under ªFluids, Lubricants and Genuine
Partsº in this section. It is important that the transmission
fluid be maintained at the prescribed level using the
recommended fluid.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
CAUTION!
Using a transmission fluid other than the manufac-
turer's recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer's recommended fluid will result in
more frequent fluid and filter changes. For correct
fluid type, refer to ªAutomatic Transmissionº under
ªFluids, Lubricants and Genuine Partsº in this
section.
Transfer Case
Inspect the transfer case for fluid leaks. If a fluid leak is
evident the transfer case fluid level may be low. Have the
transfer case serviced immediately.

add as needed.
²Check all lights and other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the brake hoses and lines.

Required Maintenance Intervals
NOTE:** Vehicles built with the 4.7L engine are
equipped with 16 spark plugs; one set is located on the
top of the engine under the coils and the second set is
located on the side of the engine.
The spark plugs located under the coils are a standard
plug and must be changed every 30,000 miles (50 000
km).
The spark plugs located on the side of the engine are a
premium plug and must be changed every 102,000 miles
(170 000 km).
