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 air dam is held in place by
two bolts and 10 snaps accessible from underneath the
front fascia.
To remove the air dam:
1. Remove the two outboard air dam bolts.
2. With a at-blade tool, disengage the snaps.
3. After the bolts are removed and the snaps are
disengaged, push forward on the air dam until it
is free.
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.
After off-roading, be sure to reinstall the air dam:
1. Line up the snaps and push the air dam rearward
to engage the snaps.
2. Install the two outboard bolts.Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher than the
seatbacks can be thrown forward during a
sudden stop. You or your passengers could
be injured. Keep cargo below the top of the
seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough terrain.
You or your passengers can be struck by
ying objects. Secure the cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to roll
over. You can be seriously or fatally injured if
the vehicle rolls over. Put heavy loads inside
the cargo area, not on the roof. Keep cargo in
the cargo area as far forward and low as
possible.
5-14

There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the oor, forward
of the rear axle. Put heavier items as far forward
as you can.
Be sure the load is properly secured, so things are
not tossed around.
You will nd other important information underLoading
the Vehicle on page 5-31andTires on page 6-54.
Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. We recognize these concerns and urge every
off-roader to follow these basic rules for protecting
the environment:
Always use established trails, roads, and areas that
have been specially set aside for public off-road
recreational driving and obey all posted regulations.
Avoid any driving practice that could damage
shrubs, owers, trees, or grasses or disturb wildlife.
This includes wheel-spinning, breaking down
trees, or unnecessary driving through streams or
over soft ground.
Always carry a litter bag and make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open res (where
permitted), camp stoves, and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch re from
the heat of the vehicle’s exhaust system.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to a remote area. Know the terrain and plan your
route. Get accurate maps of trails and terrain. Check to
see if there are any blocked or closed roads.
It is also a good idea to travel with at least one other
vehicle in case something happens to one of them.
For vehicles with a winch, be sure to read the winch
instructions. In a remote area, a winch can be handy if
you get stuck but you will want to know how to use
it properly.
Getting Familiar with Off-Road Driving
It is a good idea to practice in an area that is safe
and close to home before you go into the wilderness.
Off-roading requires some new and different skills.
Tune your senses to different kinds of signals. Your eyes
need to constantly sweep the terrain for unexpected
obstacles. Your ears need to listen for unusual tire
or engine sounds. Use your arms, hands, feet, and body
to respond to vibrations and vehicle bounce.
5-15

The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR). To nd
out the actual loads on the front and rear axles,
you need to go to a weigh station and weigh
the vehicle. Your dealer/retailer can help you with
this. Be sure to spread out the load equally on
both sides of the center line.
Never exceed the GVWR for the vehicle, or the
GAWR for either the front or rear axle.
And, if you do have a heavy load, it should be
spread out.
{CAUTION:
In the case of a sudden stop or collision,
things carried in the bed of your truck could
shift forward and come into the passenger
area, injuring you and others. If you put
things in the bed of your truck, you should
make sure they are properly secured.
{CAUTION:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on
the vehicle can break, and it can change the
way your vehicle handles. These could cause
you to lose control and crash. Also,
overloading can shorten the life of the
vehicle.
The vehicle warranty does not cover parts or
components that fail because of overloading.
The label will help you decide how much cargo
and installed equipment the truck can carry.
Using heavier suspension components to get
added durability might not change your weight
ratings. Ask your dealer/retailer to help you load
the vehicle the right way.
5-35

If you put things inside the vehicle — like suitcases,
tools, packages, or anything else — they go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that some
of them are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
There is also important loading information for
off-road driving in this manual. See “Loading Your
Vehicle for Off-Road Driving” underOff-Road
Driving on page 5-12.Add-On Equipment
When you carry removable items, you may need
to put a limit on how many people you can
carry inside the vehicle. Be sure to weigh the
vehicle before you buy and install the new
equipment.
Notice
:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
The Cargo Weight Rating (CWR) is the maximum
weight of the load the vehicle can carry. It
does not include the weight of the people inside.
But you can gure about 150 lbs (68 kg) for
each seat.
The total cargo load must not be more than the
vehicle’s CWR.
Automatic Level Control
The automatic level control rear suspension
comes as a part of the Road Sensing Suspension.
SeeRoad Sensing Suspension on page 5-9.
This type of level control is fully automatic and will
provide a better leveled riding position as well
as better handling under a variety of passenger
and loading conditions. An air compressor

Driving with a Trailer
{CAUTION:
When towing a trailer, exhaust gases may collect
at the rear of the vehicle and enter if the liftgate,
trunk/hatch, or rear-most window is open.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
To maximize safety when towing a trailer:
Have the exhaust system inspected for leaks
and make necessary repairs before starting
a trip.
Never drive with the liftgate, trunk/hatch, or
rear-most window open.
Fully open the air outlets on or under the
instrument panel.
Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 2-45.Towing a trailer requires a certain amount of experience.
Get to know the rig before setting out for the open
road. Get acquainted with the feel of handling and
braking with the added weight of the trailer. And always
keep in mind that the vehicle you are driving is now
longer and not as responsive as the vehicle is by itself.
Before starting, check all trailer hitch parts and
attachments, safety chains, electrical connectors, lamps,
tires and mirror adjustments. If the trailer has electric
brakes, start the vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This checks the electrical
connection at the same time.
During the trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving the vehicle without a trailer. This
can help to avoid situations that require heavy braking
and sudden turns.
Passing
More passing distance is needed when towing a trailer.
Because the rig is longer, it is necessary to go much
farther beyond the passed vehicle before returning to
the lane.
