transfer case NEUTRAL (N) button until the NEU-
TRAL (N) indicator light turns off. After the NEU-
TRAL (N) indicator light turns off, release the NEU-
TRAL (N) button. After the NEUTRAL (N) button
has been released, the transfer case will shift to the
position indicated by the selector switch.
NOTE: When shifting the transfer case out of NEUTRAL
(N), the engine should remain OFF to avoid gear clash.

• Steps 3 through 5 are requirements that must be met
before pressing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met before push-
ing the NEUTRAL (N) button or are no longer met
during the shift, the NEUTRAL (N) indicator light will
flash continuously until all requirements are met or
until the NEUTRAL (N) button is released.
• The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.

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 not be 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.
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 do
not 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

CAUTION!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. Run the engine at idle, in PARK, to
warm the fluid.
9. Reinsert the dipstick. Check for leaks. Release the
parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure 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. Fluid And Filter Changes — Six Speed
Transmission
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter(s) if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and chemicals that are sprayed
on trees and road surfaces during other seasons, are
highly corrosive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne contami-
nants, road surfaces on which the vehicle is operated,600 MAINTAINING YOUR VEHICLE

Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic trans-
mission and fill as needed.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following
pages for required maintenance. 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 automatic transmission fluid if equipped
with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses
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.
• Lube the front drive shaft fitting. 8MAINTENANCE SCHEDULES 633
