m
4 (Four-Wheel-Drive High): Use this setting
when you need extra traction, such as on snowy or
icy 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
•
Shifting should be made using quick motions.
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 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, and make the transfer case harder to
shift and run noisier.
•
If the transfer case shifter is in the NEUTRAL
position and you have difficulty reaching the
selected transfer case mode, with the engine
running, shift the transmission momentarily to
drive and then back to 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.
•
Shift the transfer case lever in one continuous
motion into either the Four-Wheel-Drive High
or Two-Wheel-Drive High position.
•
In extremely cold weather, it may be
necessary to slow or stop the vehicle to
shift into Four-wheel-Drive High until your
vehicle has warmed up.
•
While in Four-Wheel-Drive High, your vehicle
can be driven at any posted legal speed limit.
