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 at-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 ow to the engine.
Always be sure to replace the front fascia air
dam when you are nished 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.
Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary maintenance
and service work done. Check to make sure all
underbody shields, if the vehicle has them, are properly
attached. Be sure you read all the information about your
four-wheel-drive vehicle in this manual. Is there enough
fuel? Is the spare tire fully in ated? Are the uid levels up
where they should be? What are the local laws that apply
to off-roading where you will be driving? If you do not
know, you should check with law enforcement people in
the area. Will you be on someone’s private land? If so,
be sure to get the necessary permission.
