not been met.
• If the vehicle is equipped with Quadra-Lift
air suspension, the engine should be
started and left running for a minimum of
60 seconds (with all the doors closed) at
least once every 24 hours. This process
allows the air suspension to adjust the
vehicle’s ride height to compensate for
temperature effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your
vehicle for normal usage.
1. Bring the vehicle to a complete stop,

4. Turn the ignition to the LOCK/OFF mode.
5. Start the engine.
6. Press and hold the brake pedal.
7. Shift the transmission into NEUTRAL.8. Using a ballpoint pen or similar object,
push and hold the recessed transfer case
NEUTRAL (N) button (located by the se-

been released, the transfer case will shift
to the position indicated by the selector
switch.
10. Shift the transmission into PARK. Turn
the engine OFF.
11. Release the brake pedal.
12. Disconnect vehicle from the tow vehicle.
13. Start the engine.14. Press and hold the brake pedal.
15. Release the parking brake.
16. Shift the transmission into DRIVE, re-
lease the brake pedal, and check that
the vehicle operates normally.
NOTE:
• Steps 1 through 5 are requirements that
must be met before pushing 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
pushing 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 must be in the ON/RUN mode
for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indicator
lights will be on or flashing.

At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of the coolant reser-
voir, and brake master cylinder; add fluid as
needed.
• Check all lights and other electrical items
for correct operation.At Each Oil Change
• 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.
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.
