Luggage Carrier
If the vehicle has this feature, cargo
can be loaded on top of the vehicle.
The luggage carrier consists of
siderails attached to the roof.
The crossrails attach into the
siderails and can be moved back
and forth to accommodate various
cargo sizes.
Notice:Loading cargo on the
luggage carrier that weighs more
than 250 lbs. (113 kg) or hangs
over the rear or sides of the
vehicle may damage the vehicle.
Load cargo only on top of the
crossrails and tie the cargo down
to the crossrail support cargo
tie-down loops, making sure
to fasten it securely
Do not exceed the maximum vehicle
capacity when loading your vehicle.
For more information on vehicle
capacity and loading, seeLoading
the Vehicle on page 4-35.Adjusting the Crossrails

1. Turn the crossrail key
counterclockwise to unlock the
crossrail end cap.
2. Remove the end cap.
3. Pull the lever labeled “PULL”
from left to right to loosen the
crossrail.
4. Repeat Steps 1 through 3 to the

This tab prevents the crossrail from
being moved past the opening of
the sunroof and cargo from
being loaded too far forward.
The vehicle may have cargo tie
downs. Once the cargo is loaded
onto the crossrails, use the cargo tie
downs to secure it. Do not load

Features and Controls 2-51

Automatic Headlamp
System
When it is dark enough outside,
the automatic headlamp system
will turn on after the transmission
has been shifted from P (Park) to
D (Drive). The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on.
The system can turn on the
headlamps when driving in a parking
garage, through a tunnel or when
there is 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 system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it will take about 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.
SeeInstrument Panel Brightness on
page 3-15.
Off-Road Lamps
The off-road lamps, if the vehicle
has them, provide auxiliary lighting
when the vehicle is used off
road. These lamps are not intended
to be used in place of existing
vehicle lighting. The lamps are not
to be used on any public street
or highway and are to be covered
when not in use. Check your
state and local laws before installing
or using any auxiliary lighting. In
some states it may be necessary to
remove the roof lamps when
operating the vehicle on the
highway.
3-14 Instrument Panel

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.

oor can be tossed about
when driving over rough
terrain. You or your
passengers can be struck by
ying objects. Secure the

(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.
