NOTE:
•The transfer case cannot be shifted into NEUTRAL
from the 4WD AUTO (if equipped) position.
•Steps 1 through 5 are requirements that must be met
prior to depressing the transfer case NEUTRAL button
and must continue to be met until one second elapses
and the shift has been completed. If any of these
requirements (with the exception of step 3 - key ON)
are not met prior to pressing the NEUTRAL button, or
are no longer met during the one second time, then all
of the mode position indicator lights will flash con-
tinuously until all requirements are met or until the
NEUTRAL button is released.
•The ignition key must be ON for a transfer case shift to
take place and for the position indicator lights to be
operable. If the key is not ON, the shift will not take
place and no position indicator lights will be on or
flashing.
•The flashing NEUTRAL position indicator light indi-
cates that shift requirements have not been met.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.

4. Place the shift lever momentarily into each gear posi-
tion 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 “HOT”
(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
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 transmission below
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at approximately 70°F (21°C) (room tem-
perature). If the fluid level is correctly established at room temperature, 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.
7. Check for leaks. Release the 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.
