roads or in most off-road situations.
This setting also engages the front
axle to help drive your vehicle. This
is the best setting to use when
plowing snow.
You can shift from Two-Wheel Drive
High to Four-Wheel Drive High or
Four-Wheel Drive High to
Two-Wheel Drive High while the
vehicle is moving. In extremely cold
weather, it may be necessary to
stop or slow the vehicle to shift into
Four-Wheel Drive High.
When Using the Manual
Transfer Case
Shifts into or out of Four-Wheel
Drive Low or N (Neutral) should
be made using quick motions to
avoid excessive gear grinding.
Shifting slowly may make it more
difficult to shift.
You may notice that it is harder
to shift when the vehicle is cold.
After the vehicle warms up, the
shifting will return to normal.
While in Four-Wheel Drive High
or Four-Wheel Drive Low you
may experience reduced fuel
economy.
Avoid driving in four-wheel drive
on clean, dry pavement. It may
cause your tires to wear faster,
make the transfer case harder to
shift, and run noisier.
If the transfer case shift lever is
in the N (Neutral) position and
you have difficulty reaching the
selected transfer case mode,
with the engine running, shift the
transmission momentarily to
D (Drive) and then back to
N (Neutral). This will realign the
gear teeth in the transfer case
and allow you to complete the
shift.
Shifting from Two-Wheel Drive
High to Four-Wheel Drive High
Shifts between Two-Wheel Drive
High and Four-Wheel Drive High
can be made at any vehicle
speed.
Driving and Operating
Shift the transfer case shift lever
in one continuous motion into
either the Four-Wheel Drive High
or Two-Wheel Drive High
position.
Shifting from Two-Wheel Drive
High to Four-Wheel Drive High
while the vehicle is in motion
may require that moderate force
be applied to the shift lever for a
few seconds before Four-Wheel
Drive High can be engaged,
especially in cold weather.
In extremely cold weather, it may
be necessary to slow or stop the
vehicle to shift into Four-Wheel
Drive High.
While in Four-Wheel Drive High,
the vehicle can be driven at any
posted legal speed limit.
