inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt. Air Bag Warning Light
The light should come on and remain on for
four to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light is
not lit during starting, see your authorized
dealer. If the light stays on, flickers, or comes on while
driving, have the system checked by an authorized
dealer.

Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel. Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or

CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty-cycle based, which
means the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN position.
To turn off the message temporarily, press and release the
Trip Odometer button on the instrument cluster. To reset
the oil change indicator system (after performing the
scheduled maintenance), refer to the following procedure:
Turn the ignition switch to the ON/RUN position (do not
start the engine). Fully depress the accelerator pedal slowly three times
within 10 seconds.
Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
25. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is a part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the ignition
is in the ON position before engine start. If the bulb does
not come on when turning the key from OFF to ON/
RUN, have the condition checked promptly.

CAUTION! (Continued)• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure. Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding 1 U.S. Quart (0.95L) of oil when the
reading is at the bottom of the SAFE zone will result in a
reading at the top of the safe zone on these engines.566 MAINTAINING YOUR VEHICLE

4. Place the shift lever momentarily into each gear posi-
tion (allowing time for the transmission to fully en-
gage in each position), ending with the shift 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 reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
The fluid level should be between the HOT (upper)
reference holes on the dipstick at normal operating
temperature. 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 a minimum of two minutes for the
oil to fully drain into the transmission before recheck-
ing the fluid level. NOTE:
• The holes in the dipstick will be full of fluid if the
actual level is at or above the hole.
• 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.
CAUTION!Be aware that if the fluid temperature is below 50° F
(10° C), it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.

Adding Fluid
Fluid should be added only at filler hole until fluid
begins to run out of the hole.
Drain
First remove the fill plug (B), then the drain plug (C). The
recommended tightening torque for the drain and fill
plugs is 15 to 25 ft lbs (20 to 34 N·m).
CAUTION!When replacing the plugs, do not overtighten them.
You could damage them and cause them to leak.
Selection Of Lubricant
Use only manufacturer’s recommended fluid. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information. Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
Fluid Level Check
Lubricant should be at the bottom edge of the oil fill hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.590 MAINTAINING YOUR VEHICLE
