3. Move the 4x4 control to the 4x4
HIGH or 2WD position.

for more than 10 seconds, allow the
vehicle to move at a speed below
5 mph (8 km/h), then repeat steps 2
through 5 while the vehicle is rolling
before reporting any shift concerns to your authorized dealer.
Driving off-road with truck and utility vehicles
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
Your vehicle may be equipped with a long front air dam that may become
damaged (due to reduced ground clearance) when taking your vehicle
off-road. This air dam can either be removed or a shorter air dam can be
purchased from your authorized dealer. In either case, if the air dam is
to be removed (or replaced) before going off-road, refer to the
Workshop Manual for the procedure or have your authorized dealer
perform the work for you.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
