Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, seeVehicle
Load Limits on page 9‑24.
.If small heavy objects are
placed on the roof, cut a piece of
3/8 inch plywood to fit inside the
crossrails and siderails to spread
the load. Tie the plywood to the
siderail supports.
.Tie the load and secure it
to the crossrails or the siderail
supports. Use the crossrails only
to keep the load from sliding.
To move a crossrail, lift the
release lever up, on both sides
of the rail. Then slide the
crossrail to the desired position
balancing the force side to side.
Press the release lever down on
both sides of the rail, down to
tighten it. Try to slide the
crossrail back and forth slightly
to make sure it is tight.
.To carry long items, move the
crossrails as far apart as
possible. Tie the load to the
crossrails and the siderails or
siderail supports. Also tie the
load to the bumpers, but do not
tie the load so tightly that the
crossrails or siderails are
damaged.
.After moving a crossrail, be
sure it is securely locked into
the siderail.
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass.
Make sure items loaded on the roof
of the vehicle do not block or
damage the CHMSL.

4. Press the trip/fuel button untilthe vehicle heading, for
example, N for North, is
displayed in the DIC. Or, if the
vehicle does not have DIC
buttons, press and hold the
trip odometer reset stem for
two seconds to select the next
available variance zone. Repeat
this step until the appropriate
variance zone is displayed.
5. If calibration is necessary, calibrate the compass.
See “Compass Calibration
Procedure” following. Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an
open parking lot, where driving the
vehicle in circles is not a danger.
It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB or
cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle, move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone
is set to the variance zone in
which the vehicle is located.
See “Compass Variance (Zone)
Procedure” earlier in this
section.
Do not operate any switches
such as window, sunroof,
climate controls, or seats during
the calibration procedure.
2. Press the vehicle information button until PRESS
VTO
CALIBRATE COMPASS
displays. Or, if the vehicle does
not have DIC buttons, press the
trip odometer reset stem until
CALIBRATE COMPASS
displays.

6-4 Lighting
Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps along with
other lamps such as the taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover this sensor or
the system will come on whenever
the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage, a tunnel, or while
driving in heavy overcast weather.
This is normal.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp systems so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system is only affected
when the light sensor sees a
change in lighting lasting longer
than the delay.If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately one minute
for the automatic headlamp system
to change to DRL if it is light
outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6‑6.

Infotainment System 7-13
Static can also occur when things
like storms and power lines interfere
with radio reception. When this
happens, try reducing the treble on
the radio.
FM Stereo
FM signals only reach about
16 to 65 km (10 to 40 miles).
Although the radio has a built-in
electronic circuit that automatically
works to reduce interference, some
static can occur, especially around
tall buildings or hills, causing the
sound to fade in and out.
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 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.
Satellite Radio Antenna
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
(if equipped) may be affected if the
sunroof is open.

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 under
Vehicle Load
Limits on page 9‑24 andTires on
page 10‑49.
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, flowers,
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
fires (where permitted), camp
stoves, and lanterns.
.Never park your vehicle over
dry grass or other combustible
materials that could catch fire
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.
