Shifting Into Four-Wheel Drive Low
When Four-Wheel Low is engaged, vehicle
speed should be kept below 45 mph. Extended
high-speed operation in 4L may damage or
shorten the life of the drivetrain.
To shift to the Four-Wheel Drive Low position, the
ignition must be in RUN and the vehicle must
be stopped or moving less than 3 mph (5 km/h)
with the transmission in NEUTRAL (N). The
preferred method for shifting into Four-Wheel Drive
Low is to have your vehicle moving 1 to 2 mph
(1.6 to 3.2 km/h). Turn the knob to the Four-Wheel
Drive Low position. You must wait for the
Four-Wheel Drive Low indicator light to stop
ashing and remain on before shifting your
transmission in gear.Notice:Shifting the transmission into gear
before the Four-Wheel Drive Low indicator light
has stopped ashing could damage the
transfer case. To help avoid damaging your
vehicle, always wait for the Four-Wheel
Drive Low indicator light to stop ashing
before shifting the transmission into gear.
The vehicle may have signi cant engagement noise
and bump when shifting between Four-Wheel Drive
Low and Four-Wheel Drive High ranges or from
NEUTRAL while the engine is running.
If the knob is turned to the Four-Wheel Drive Low
position when your vehicle is in gear and/or
moving, the Four-Wheel Drive Low indicator light
will ash for 30 seconds and not complete the
shift unless your vehicle is moving less than 3 mph
(5 km/h) and the transmission is in NEUTRAL (N).
After 30 seconds the transfer case will shift to
Four-Wheel Drive High mode.

Shifting Out of Four-Wheel Drive Low
To shift from Four-Wheel Drive Low to Four-Wheel
Drive High, AUTO, or Two-Wheel Drive High, your
vehicle must be stopped or moving less than 3 mph
(5 km/h) with the transmission in NEUTRAL (N) and
the ignition in RUN. The preferred method for
shifting out of Four-Wheel Drive Low is to have your
vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Turn
the knob to the Four-Wheel Drive High, AUTO, or
Two-Wheel Drive High position. You must wait for
the Four-Wheel Drive High, AUTO, or Two-Wheel
Drive High indicator light to stop ashing and
remain on before shifting your transmission
into gear.
Notice:Shifting the transmission into gear
before the Four-Wheel Drive Low indicator light
has stopped ashing could damage the
transfer case. To help avoid damaging your
vehicle, always wait for the Four-Wheel
Drive Low indicator light to stop ashing
before shifting the transmission into gear.
The vehicle may have signi cant engagement noise
and bump when shifting between Four-Wheel Drive
Low and Four-Wheel Drive High ranges or from
NEUTRAL while the engine is running.If the knob is turned to the Four-Wheel Drive High,
AUTO, or Two-Wheel Drive High switch position
when your vehicle is in gear and/or moving,
the Four-Wheel Drive High, AUTO or Two-Wheel
Drive High indicator light will ash for 30 seconds
but will not complete the shift unless your
vehicle is moving less than 3 mph (5 km/h) and
the transmission is in NEUTRAL (N).
Shifting into NEUTRAL
To shift the transfer case to NEUTRAL do the
following:
1. Make sure the vehicle is parked so that it will
not roll.
2. Set the parking brake and apply the regular
brake pedal. SeeParking Brake on page 138
for more information.
3. Start the vehicle or turn the ignition to RUN.
4. Put the transmission in NEUTRAL (N).
5. Shift the transfer case to Two-Wheel
Drive High.
136
6. Turn the transfer case dial clockwise to
NEUTRAL till it stops and hold it for
10 seconds. Then slowly release the dial to
the four low position. The NEUTRAL light will
come on when the transfer case shift to
NEUTRAL is complete.
7. If the engine is running, verify that the
transmission is in NEUTRAL (N) by shifting
the transmission to REVERSE (R) for
one second, then shift the transmission to
DRIVE (D) for one second.
8. Turn the ignition to ACCESSORY, which will
turn the engine off.
9. Place the transmission shift lever in PARK (P).
10. Release the parking brake prior to moving
the vehicle.
11. Turn the ignition to LOCK.
Shifting Out of NEUTRAL
To shift out of NEUTRAL do the following:
1. Set the parking brake and apply the regular
brake pedal.
2. Shift the transmission to NEUTRAL (N) and
turn the ignition to RUN with the engine off.3. Turn the transfer case dial to the desired
transfer case shift position (Two-Wheel
Drive High, Four-Wheel Drive High, AUTO).
After the transfer case has shifted out of
NEUTRAL the NEUTRAL light will go out.
4. Release the parking brake prior to moving
the vehicle.
Notice:Shifting the transmission into gear
before the Four-Wheel Drive Low indicator
light has stopped ashing could damage the
transfer case. To help avoid damaging
your vehicle, always wait for the Four-Wheel
Drive Low indicator light to stop ashing
before shifting the transmission into gear.
5. Start the engine and shift the transmission to
the desired position.
Excessively shifting the transfer case into or out
of the different modes may cause the transfer
case to enter the shift protection mode. This will
protect the transfer case from possible damage
and will only allow the transfer case to respond
to one shift per 10 seconds. The transfer case
may stay in this mode for up to three minutes.
137
If the ignition is on when the parking brake is
released, the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 414.
