Shifting from Four-Wheel High to
Two-Wheel High
Press and release the Two-Wheel High button.
This can be done at any speed, and the front
axle will unlock automatically.
It is normal to hear and feel your vehicle's transfer
case shift into Four-Wheel High. If you shift with
the vehicle stopped, the indicator light may
still flash slowly. It may be necessary to shift the
transmission momentarily into REVERSE (R)
and DRIVE (D), for an automatic transmission,
or REVERSE (R) and FIRST (1) for a manual
transmission to have the light stop flashing.
Shifting from Two-Wheel High or
Four-Wheel High to Four-Wheel Low

to Four-Wheel Low, the vehicle must be stopped
or moving less than 3 mph (5 km/h) with the
transmission in NEUTRAL (N) for an automatic
transmission or the clutch pedal pressed for
a manual transmission. The preferred method for
shifting into Four-Wheel Low is to have your
vehicle moving 1 to 2 mph (1.6 to 3.2 km/h).
Press and release the Four-Wheel Low button.
You must wait for the Four-Wheel Low indicator
light to stop flashing and stay on before shifting
the transmission into gear or releasing the
clutch pedal.
If the Four-Wheel Low button is pressed when
your vehicle is in gear and/or moving faster
than 3 mph (5 km/h), the four-wheel low indicator
light will flash for 30 seconds and not complete
the shift.
