Storage Areas
Glove Box
Open the glove box by pulling the bottom of the
handle upward.
Center Overhead Console
Your vehicle is equipped with either a short or long
overhead console.
To open a door on the console, push on the rear edge
of the door and let it swing open. Push the door up
until it latches to close the door.
The overhead consoles also includes reading lamps, the
Universal Home Remote System buttons and the
sunroof switch (if equipped).
Center Console Storage Area
Your vehicle has a console compartment between the
bucket seats.
To open it, press the button on the side of the console
and swing the console lid open.
Luggage Carrier
If your vehicle has this feature, you can load cargo on
your 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 securing
various cargo sizes.
Notice:Loading cargo on the luggage carrier that
weighs more than 300 lbs. (136 kg) or hangs
over the rear or sides of the vehicle may damage
your 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.
Your vehicle may be equipped with a light bar, do not
load cargo on it. SeeOff-Road Lamps on page 3-17for
more information.
Do not exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading Your Vehicle on
page 4-55.
2-54

Adjusting the Crossrails
Adjust the crossrails to t your load by doing the
following:
1. Loosen the lock knobs on the crossrail supports by
turning the knobs counterclockwise. Only loosen
them enough to allow the crossrails to slide easily.
2. Slide the crossrails to the desired position, being
sure to align the lines in the side rails with the
arrows on the crossrail supports.3. Tighten the lock knobs and then try to move the
crossrails back and forth to be sure that they do
not move.
4. Once you load the cargo onto the crossrails, secure
it by tying it down to the crossrail support cargo
tie-down loops. Do not load cargo directly on
the roof of your vehicle.
Be sure you do not cover the roof marker lamps or
the Center-High-Mounted Stoplamp (CHMSL) (If
equipped) with cargo.
To prevent damage or loss of cargo check now and
then to make sure the luggage and cargo are still
securely fastened and the crossrails are tight.
Stop Tabs
If your vehicle has a sunroof, it will have a crossrail stop
tab placed in the siderail in the location labeled
SUNROOF STOP. This tab prevents you from moving
the crossrails past the opening of the sunroof and
loading cargo too far forward.
2-55

If your vehicle has the OnStar and navigation system, it
will have a crossrail stop tab placed in the siderail in
the location labeled OnSTAR STOP. This tab prevents
you from moving the crossrails and cargo too close
to the OnStar antenna, which could cause the system to
function improperly or not at all.
Vehicles with the off-road lamps will have additional
stop tabs placed in the siderails to prevent you
from moving the lamps too far rearward, causing them
to shine into the optional sunroof opening.
Crossrail Channels
Notice:If you drive your vehicle through an
automatic car wash that does not have enough
clearance for any roof-mounted accessories (such
as off-road lamps or a roof basket) on your vehicle,
you can damage your vehicle. To avoid damaging
your vehicle in a car wash, remove any
roof-mounted accessories if you can, and do not
use an automatic car wash while roof-mounted
accessories are on your vehicle. SeeWashing Your
Vehicle on page 5-109for more information.
The crossrails have built in channels to allow you to
attach other items designed for this system, such
as basket luggage carriers, bike racks, ski racks, etc.
2-56

Removal and Cleaning
To ensure that the water management system performs
properly, be sure that the midgate, tailgate and cover
system are fully closed and that each element of
the water management system is clean and not blocked
with debris. Follow the instruction given next in this
section for the proper procedures on cleaning each item
of the water management system.
Side Rail Channels
The side rail channels are located on top of both sides
of the roof and the cargo area. You may want to
ush them out with clean water if you notice any debris
collecting inside of them.
When loading cargo into the cargo area, be careful not
to damage the rails.
For more information on this feature seeLuggage
Carrier on page 2-54.
Cargo Area Floor Drains
Your vehicle also has four cargo-area oor drains (A)
located under the cargo mat, if equipped, near the sides
of the cargo area. These drains should be cleaned
periodically to allow water to exit the cargo area.
The cargo mat has cutouts for the drains. You can ush
the drains through the cutouts, but if the cargo area
is extremely dirty you can lift up the edges of the cargo
oor mat or take the whole mat out and ush the
drains with water. The drain grates can be removed by
using a at-head screwdriver to clear any debris that
has accumulated in the drain.
2-59

You will be able to open the cover by turning the cover
release latch in a clockwise direction, which will allow
you to lift the cover with the assistance of the struts.
Sunroof
The vehicle may have a
power sliding sunroof. The
ignition must be on or in
the accessory position,
or Retained Accessory
Power (RAP) must
be active.
SeeRetained Accessory Power (RAP) on page 2-25.
The switch used to operate the sunroof is located in the
overhead console.
2-61

Express-Open/Close Sunroof
The sunroof has a feature which allows the sunroof
panel to be opened or closed without continuously
pressing the switch. The express-open can be stopped
at any time by pushing the front of the switch a
second time.
The sunroof has four positions:
Comfort open stop:To open the sunroof and
sunshade, press the rear of the switch quickly and
release. The glass panel will open to an interim
position that reduces wind noise. For information on
using the sunshade, see “Sunshade Operation” later.
Full open stop:To open the sunroof further, press
the rear of the switch quickly once more.
Express close:To close the sunroof, press the front
of the switch quickly and release.
Vent:The vent position allows the rear of the sunroof
to be opened and tilted upward. With the sunroof in
the fully closed position, press and hold the front of
the switch until the sunroof reaches the desired vent
position or until it stops moving. To close the sunroof
from the vent position, press and hold the rear of the
switch until the sunroof is fully closed.
Do not leave the sunroof open for long periods of time
as debris may collect in the tracks.
Anti-Pinch Protection Feature
If something gets caught between the glass panel and
roof frame while the sunroof is closing, the glass
panel will stop and open half way, and the deector will
raise fully.
If something gets caught between the glass panel and
the roof frame during the tilt down operation, the
glass panel will stop and open fully.
If the sunroof panel receives a strong impact, the
anti-pinch protection feature may work even if nothing
gets caught between the glass panel and roof frame.
Do not to leave the sunroof open for long periods of time
as debris may collect in the tracks.
Sunshade Operation
The sunshade will open automatically when opening
the sunroof.
However, it can manually be pulled shut after the
sunroof is closed. To adjust the sunshade, push it
backward or pull it forward to the desired position. The
sunshade cannot be adjusted further than the current
closed position of the sunroof.
Notice:If you force the sunshade forward of the
sliding glass panel, damage will occur and the
sunroof may not open or close properly. Always
close the glass panel before closing the sunshade.

;(Parking Lamps):Turn the control to this position to
turn on the parking lamps, together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Roof Marker Lamps
Instrument Panel Lights
2(Headlamps):Turn the control to this position to
turn on the headlamps, together with the previously
listed lamps and lights.
When the vehicle is turned off and the headlamps are in
AUTO, the headlamps may automatically remain on
for a set time. You can change this delay time using the
DIC. SeeDriver Information Center (DIC) on page 3-45.
You can switch your headlamps from low to high-beam
by pushing the turn signal/multifunction lever toward
the instrument panel.
Headlamps on Reminder
If a door is open, a reminder chime will sound when your
headlamps or parking lamps are manually turned on and
your key is out of the ignition. To turn off the chime, turn
the headlamp switch to off or AUTO and then back on. In
the AUTO mode, the headlamps turn off once the ignition
is in LOCK or may remain on until the headlamp delay
ends (if enabled in the DIC).
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on,
the exterior lamps control is in AUTO, if enabled,
the transmission is not in PARK (P), and
the light sensor determines it is daytime.
3-15

When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp system will
turn on your headlamps at the normal brightness
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. Turning off the automatic headlamp system
with the headlamp switch is not available for vehicles
rst sold in Canada. For vehicles rst sold in Canada,
you can turn off the automatic headlamp system
when parked at night by applying the parking brake
before starting your vehicle. The headlamps will remain
off once the vehicle is started for as long as you are
parked. If you release the parking brake, the lights willturn on. If the parking brake is not released before you
begin to drive, the exterior lamps will turn on above
2 mph (3.2 km/h).
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. 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 will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-17.
