Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged as long as it is securely attached
to the base. If the mast becomes slightly bent, straighten
it out by hand. If the mast is badly bent, replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand until fully seated plus one quarter turn.
XM™ Satellite Radio Antenna

Loading Your Vehicle for Off-Road
Driving
{WARNING:
•Cargo on the load floor 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 floor can be
tossed about when driving over rough terrain.
You or your passengers can be struck by
flying objects. Secure the cargo properly.
WARNING: (Continued)
WARNING: (Continued)
•
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.
There are some important things to remember about
how to load your vehicle.
•The heaviest things should be on the floor, 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 find other important information underLoading
the Vehicle on page 5-33andTires on page 6-57.
5-14

{WARNING:
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.
Using heavier suspension components to get
added durability might not change your weight
ratings. Ask your dealer/retailer to help you load
your vehicle the right way.
Notice
:Overloading the vehicle may cause
damage. Repairs would not be covered by the
vehicle warranty. Do not overload the vehicle.
If you put things inside your vehicle — like
suitcases, tools, packages, or anything
else — they will 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.
{WARNING:
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 5-13.
Remember not to exceed the Gross Axle Weight
rating (GAWR) of the front or rear axle.
5-39

Two-Tiered Loading
By positioning four 2” X 6” wooden planks across
the width of the pickup box, you can create an
upper load platform. The planks must be inserted
in the pickup box depressions. The length of
the planks must allow for at leasta2cm(3/4 inch)
bearing surface on each end of the plank.
When using this upper load platform, be sure the
load is securely tied down to prevent it from
shifting. The load’s center of gravity should be
positioned in a zone over the rear axle.
Any load that extends beyond the vehicle’s
taillamp area must be properly marked according
to local laws and regulations.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the rear axle.
Add-On Equipment
When you carry removable items, you may need
to put a limit on how many people you carry
inside your vehicle. Be sure to weigh your vehicle
before you buy and install the new equipment.
Notice
:Overloading the vehicle may cause
damage. Repairs would not be covered by the
vehicle warranty. Do not overload the vehicle.Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the rear axle.
A reinforcement kit for mounting a toolbox is
recommended. See your dealer/retailer.
Truck-Camper Loading Information
The vehicle was neither designed nor intended
to carry a slide-in type camper.
Notice
:Adding a slide-in camper or similar
equipment to the vehicle can damage it,
and the repairs would not be covered by the
vehicle warranty. Do not install a slide-in
camper or similar equipment on the vehicle.
Pickup Conversion to Chassis Cab
We are aware that some vehicle owners might consider
having the pickup box removed and a commercial or
recreational body installed. However, we recommend
that conversions of this type not be done to pickups.
Owners should be aware that, as manufactured, there
are differences between a chassis cab and a pickup with
the box removed which could affect vehicle safety.
