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 trans-
mission control systems. When these systems are operatingproperly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions 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

WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Master Cylinder — Brake Fluid Level Check
Check the fluid level in the master cylinder immediately if
the “Brake Warning Light” indicates system failure.
Check the fluid level in the master cylinder when perform-
ing underhood services.
Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to bring the fluid level up to
the requirements described on the brake fluid reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Fluid level can be expected to fall as the brake pads wear.
Brake fluid level should be checked when pads are re-
placed. However, low fluid level may be caused by a leak
and a checkup may be needed.Use only manufacturer’s recommended brake fluid. Refer
to “Fluids, Lubricants, And Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.

450 MAINTAINING YOUR VEHICLE
WARNING!(Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid. Refer
to “Fluids, Lubricants, And Genuine Parts” in this section
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid. No chemical flushes should be used in any
transmission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, And Genu-
ine Parts” in this section for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission.
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid additives
to the transmission. The only exception to this policy is the
use of special dyes for diagnosing fluid leaks. Avoid using
transmission sealers as they may adversely affect seals.7
MAINTAINING YOUR VEHICLE 451
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check — Four-Speed Automatic
Transmission
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Run the engine at normal idle speed for at least 60seconds, and leave the engine running for the rest of this
procedure.
3. Fully apply the parking brake, and press the brake pedal.
4. Place the gear selector momentarily into each gear position (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
5. Wipe the area around the dipstick clean to prevent dirt from entering the transmission. 6. Remove the dipstick and determine if the fluid is hot or
cold. You can also read the transmission fluid tempera-
ture using the instrument cluster. Refer to Instrument
Cluster Display inUnderstanding Your Instrument
Panel for further information. Hot fluid is approxi-
mately 180°F (82°C), which is the normal operating
temperature after the vehicle is driven at least 15 miles
(24 km). Hot fluid cannot be held comfortably between
the fingertips. Cold fluid is at a temperature of approxi-
mately 80°F (27°C).
7. Wipe the dipstick clean and reinsert it until seated. Then, remove the dipstick and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole.
• If the fluid is hot, the fluid level should be in the
crosshatched area marked “HOT” (between the upper
two holes in the dipstick).
• If the fluid is cold, the fluid level should be between
the lower two holes in the area marked “COLD”.
If the fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill. After adding
any quantity of oil through the dipstick tube, wait at least
452 MAINTAINING YOUR VEHICLE
two minutes for the oil to fully drain into the transmission
before rechecking the fluid level.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick with the
fluid at approximately 80°F (27°C). If the fluid level is
correctly established at 80°F (27°C), it should be between
the HOT (upper) reference holes when the transmission
reaches 180°F (82°C). Remember it is best to check the level
at the normal operating temperature.
8. Check for leaks. Release the parking brake.
CAUTION!
•Using a transmission fluid other than the manufactur-
er’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter shud-
der, and will require more frequent fluid and filter
changes. Refer to “Fluids, Lubricants, And Genuine
Parts” in this section for fluid specifications.
• Dirt and water in the transmission can cause serious
damage. To prevent dirt and water from entering the
transmission after checking or replenishing fluid,
make sure that the dipstick cap is re-seated properly.
Fluid Level Check — Six-Speed Automatic
Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis-
sion filler tube is capped and no dipstick is provided. Your
authorized dealer can check your transmission fluid level
using a special service dipstick. If you notice fluid leakage
or transmission malfunction, visit your authorized dealer
immediately to have the transmission fluid level checked.
Operating the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit your autho-
rized dealer immediately. Severe transmission damage
may occur. Your authorized dealer has the proper tools
to adjust the fluid level accurately.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E-85 fuel usage will influence
when the “Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment or is
operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• 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, brake
master cylinder, power steering, and transmission (4-
speed only) and fill as needed.
• Check function of all interior and exterior lights.
