Four-Wheel Drive
If the vehicle has Four-Wheel Drive,
you can send the engine's driving
power to all four wheels for extra
traction.
Electronic Transfer Case
The transfer case knob is located
next to the steering column.
You can choose among four driving
settings:
2 (Two-Wheel Drive High): This
setting is used for driving in most
street and highway situations.
In Brief
4 (Four-Wheel Drive High): Use
the Four-Wheel Drive High position
when extra traction is needed, such
as on snowy or icy roads or in most
off-road situations.
4 (Four-Wheel Drive Low): This
setting sends maximum power to all
four wheels. You might choose
Four-Wheel Drive Low while driving
off-road in deep sand, deep mud,
deep snow, and while climbing or
descending steep hills.
N (Neutral): Shift the vehicle's
transfer case to N (Neutral) only
when towing the vehicle. See
Recreational Vehicle Towing on
page 10 87 or Towing the Vehicle on
page 10 87 for more information.
