XM Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United States,
and in Canada. Just as with FM, tall buildings or hills can
interfere with satellite radio signals, causing the sound to
fade in and out. In addition, traveling or standing under
heavy foliage, bridges, garages, or tunnels may cause
loss of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
causes an increased level of static while listening to
the radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Fixed Mast Antenna
The xed 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
System
The XM Satellite Radio antenna is located on the roof
of the vehicle. Keep the antenna clear of obstructions
for clear radio reception.
If the vehicle has a sunroof, the performance of the
XM system may be affected if the sunroof is open.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime level.
To change the volume level of the chime, press and hold
pushbutton 6 with the ignition on and the radio power
off. The volume level will change from the normal
level to loud, and LOUD will appear on the radio display.
To change back to the default or normal setting,
press and hold pushbutton 6 again. The volume level
will change from the loud level to normal, and NORMAL
will appear on the radio display. Each time the chime
volume is changed, three chimes will sound to indicate
the new volume selected. Removing the radio and
not replacing it with a factory radio or chime module will
disable vehicle chimes.

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.
CAUTION: (Continued)
CAUTION: (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 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 4-33andTires on page 5-54.
4-14

{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 4-12.
Remember not to exceed the Gross Axle Weight
rating (GAWR) of the front or rear axle.
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 least a 3/4 inch (2 cm)
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.
