Shifting from Four-Wheel Low to
Two-Wheel High or Four-Wheel High
To shift from four-wheel low to two-wheel high or
four-wheel high, your vehicle must be stopped or
moving less than 1.2 mph (2 km/h) with the transmission
in NEUTRAL (N) or the clutch pedal engaged.
The preferred method for shifting out of four-wheel low
is to have your vehicle moving 1.2 mph (2 km/h).
Press and release the four-wheel high button. You must
wait for the four-wheel high indicator light to stop
flashing and remain illuminated before shifting your
transmission into gear or releasing the clutch pedal.
If the four-wheel high button is pressed when your
vehicle is in gear and/or moving faster than 1.2 mph
(2 km/h), the four-wheel high indicator light will flash for
30 seconds but not complete the shift.
On vehicles with an automatic transmission, if your
transfer case does not shift into four-wheel high, your
transmission indicator switch may require adjustment.
With your transmission in NEUTRAL (N), press and
release the four-wheel high button. While the four-wheel
high indicator light is flashing, shift your transmission
into PARK (P). Wait until the four-wheel high indicator
light remains illuminated before shifting your
transmission into gear. Press the four-wheel high button
again to complete the shift. This will get you into
four-wheel high, but you should take your vehicle in for
service to restore normal operation.
Shifting to NEUTRAL
Use NEUTRAL when you plan to tow your vehicle.
See Recreational Vehicle Towing on page 4-50
for towing instructions. To shift the transfer case into
NEUTRAL do the following:
1. Set the parking brake.
2. Start the vehicle.
3. Shift the transmission in NEUTRAL (N), or press in
the clutch for vehicles with a manual transmission.
4. Shift the transfer case to two-wheel high.
5. Press and hold the two-wheel high and four-wheel
low buttons at the same time for 10 seconds. The
NEUTRAL (N) light will come on when the
transfer case shift to NEUTRAL (N) is complete.
6. Shift the transmission to REVERSE (R) for one
second, then shift the transmission to DRIVE (D)
for one second, or FIRST (1) for vehicles with
manual transmissions.
7. Turn the ignition to LOCK.
8. Place the transmission shift lever in PARK (P), or
FIRST (1) for vehicles equipped with a manual
transmission.
