4 n (Four-Wheel Low): This setting
also engages the front axle to give
you extra traction. It sends the
maximum power to all four wheels.
You might choose four-wheel low if
you were driving off-road in sand,
mud, or deep snow and while
climbing or descending steep hills.
Shifting into Four‐Wheel Low will
turn Traction Control and
StabiliTrak
® off. See Traction
Control System (TCS) on page 9‑43
and StabiliTrak
® System on
page 9‑44 for more information.
Indicator lights in the buttons show
you which setting you are in. The
indicator lights will come on briefly
when you turn on the ignition and
one will stay on the selected setting.
If the lights do not come on, you
should take the vehicle in for
service. An indicator light will flash
while shifting. It will stay on when
the shift is completed.
If the transfer case does not shift, it
will return to the last chosen setting.
Shifting from Two-Wheel High to
Four-Wheel High
Press and release the Four-Wheel
High button. This can be done at
any speed, and the front axle will
lock automatically.
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 the
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 R (Reverse) and
D (Drive), for an automatic
transmission, or R (Reverse) and
1 (First) for a manual transmission
to have the light stop flashing.
Shifting from Two-Wheel High or
Four-Wheel High to
Four-Wheel Low
To shift from Two-Wheel High or
Four-Wheel High to Four-Wheel
Low, the vehicle must be stopped or
moving less than 5 km/h (3 mph)
with the transmission in N (Neutral)
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
1.6 to 3.2 km/h (1 to 2 mph).
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 the vehicle is in gear
and/or moving faster than 5 km/h
(3 mph), the Four-Wheel Low
indicator light will flash for
30 seconds and not complete the
shift.
