Shifting Into Four-Wheel Drive High or
AUTO (Automatic Four-Wheel Drive)

This can be done at any speed, except when shifting from
Four-Wheel Drive Low. The indicator light will flash while
shifting. It will remain on when the shift is completed.
Shifting Into Two-Wheel Drive High
Turn the knob to the Two-Wheel High position. This can
be done at any speed, except when shifting from

See shifting out of Four-Wheel Drive Low later in this

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 ON/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 flashing 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
flashing could damage the transfer case. To help
avoid damaging your vehicle, always wait for the
Four-Wheel Drive Low indicator light to stop flashing
before shifting the transmission into gear.
The vehicle may have significant 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 flash 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.
