Off-Road Driving
This off-road guide is for vehicles that have
four-wheel drive. Also, see
Braking on page 360 . If
your vehicle does not have four-wheel drive,
you should not drive off-road unless you are on a
level, solid surface.
Off-road driving can be great fun. But it does have
some definite hazards. The greatest of these is
the terrain itself.
“Off-roading” means you have left the great North
American road system behind. Traffic lanes
are not marked. Curves are not banked. There are
no road signs. Surfaces can be slippery, rough,
uphill, or downhill. In short, you have gone
right back to nature.
Off-road driving involves some new skills. And that
is why it is very important that you read this
guide. You will find many driving tips and
suggestions. These will help make your off-road
driving safer and more enjoyable.
If you think you will need some more ground
clearance at the front of your vehicle, you
can remove the front fascia lower air dam.
The front fascia lower air dam is held in place by
two bolts and 10 snap features. The bolts and
snap features are accessible from underneath the
front fascia.
The following steps must be performed on the
bolts and snap features to remove the air dam:
1. Remove the two outboard air dam bolts.
2. With a flat-blade screwdriver, push down on
the snap features and disengage the snaps.
3. After the bolts are removed and the snaps are
disengaged, push forward on the air dam until
it is free.
When you are back on roads, though, be sure to
replace the air dam.
Notice: Operating your vehicle for extended
periods without the front fascia lower air
dam installed can cause improper air flow to
the engine. Always be sure to replace the front
fascia air dam when you are finished off-road
driving.
To reinstall the lower air dam do the following:
1. Line up the snap features and push the
air dam rearward to engage the snaps.
2. Install the two outboard bolts.
