setting is used for driving in most
street and highway situations.
The front axle is not engaged in
Two-Wheel Drive. This setting also
provides the best fuel economy.

the Four-Wheel Drive High position
when extra traction is needed, such
as on snowy or icy roads or in most
off-road situations. This setting also
engages the front axle to help drive
the vehicle. This is the best setting
to use when plowing snow.

setting also engages the front axle
and delivers extra torque. You may
never need this setting. It sends

Drive Low while driving off-road in
deep sand, deep mud, deep snow,
and while climbing or descending
steep hills.
