Shifting Out of 4LO

To shift from 4LO to 4HI, AUTO 4WD or 2HI your
vehicle must be stopped or moving less than 3 mph 
(4.8 km/h) with the transmission in NEUTRAL (N) and
the engine running. The preferred method for shifting
out of 4LO is to have your vehicle moving 1 to 2 mph
(1.6 to 3.2 km/h). Press and release the 4HI, AUTO
4WD or 2HI switch. You must wait for the 4HI, AUTO
4WD or 2HI indicator light to stop flashing and remain
illuminated before shifting your transmission into gear.

If the 4HI, AUTO 4WD or 2HI switch is pressed when
your vehicle is in gear and/or moving, the 4HI, AUTO
4WD or 2HI indicator light will flash for 30 seconds but
will not complete the shift unless your vehicle is moving
less than 3 mph (4.8 km/h) and the transmission is in
NEUTRAL (N).

Shifting to Neutral

To shift the transfer case to neutral, first make sure the
vehicle is parked so that it will not roll:

1. Set the parking brake.

2. Start the vehicle.

3. Connect the vehicle to the towing vehicle.

4. Put the transmission in NEUTRAL (N).

5. Shift the transfer case to 2HI.

6. Simultaneously press and hold the 2HI and 4LO

buttons for 10 seconds. The NEUTRAL light will
come on when the transfer case shift to neutral 
is complete.

7. Shift the transmission to REVERSE (R) for one

second, then shift the transmission to AUTOMATIC
OVERDRIVE 

B for one second.

8. Turn the ignition to OFF.

9. Place the transmission shift lever in PARK (P).

10. Release the parking brake prior to towing.

Shifting Out of Neutral

To shift out of neutral:

1. Set the parking brake and apply the regular brake pedal.

2. Start the vehicle with the transmission in PARK (P).

3. Press the button for the desired transfer case shift

position (2HI, 4HI, AUTO 4WD or 4LO).

4. Put the transmission in NEUTRAL (N).

5. Shift the transmission lever to the desired position.

After the transfer case has shifted out of NEUTRAL,
the light will go out.
