Section 2 Features and Controls
2-1

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
HomeLink transmitter 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
top of your vehicle.
The luggage carrier consists of siderails attached to the
roof and crossrails which can be moved back and
forth to accommodate 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.
Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading Your Vehicle on
page 4-67.
2-46

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
2-47

If your vehicle has a sunroof, it will have a crossrail stop
tab placed in the siderail in the spot labeled SUN—ROOF
STOP. This tab prevents you from moving the crossrails
past the opening of the sunroof and loading cargo too far
forward.
Your vehicle will also have a stop tab in the crossrail in
the spot labeled ON STAR STOP. This tab prevents
loading cargo too close to the OnStar antenna which will
cause the OnStar and navigation system (if equipped)
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. SeeCleaning the
Outside of Your Vehicle on page 5-95for 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.
To use the crossrail channels, do the following:
1. Use the included key to unlock the crossrail end
cap by turning it counterclockwise. If you ever
loose a key, your dealer will be able to help you
obtain a replacement.
2-48

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To operate your sunroof, the ignition needs to
be on or RAP needs to be active. See “Retained
Accessory Power” underIgnition Positions on page 2-19.
The switch used to operate the sunroof is located in
the overhead console.The sunroof is equipped with ve positions:
First open stop:To open the sunroof and
sunshade, press and hold the rear side of the switch
until the sunroof reaches the desired position or
until it reaches the rst open stop. For more
information on using the sunshade, see “Sunshade
Operation” later in this section.
Second open stop:To open it further, press and
hold the rear side of the switch until the sunroof
reaches the desired position or until it reaches the
second open stop.
Fully open:To open the sunroof completely, press
and hold the rear side of the switch until the
sunroof opens completely.
Closed:To close the sunroof, press and hold the
front of the switch until the sunroof reaches the
desired position or until it is fully closed and stops
on its own. The sunroof will not be fully seated
unless the switch is held until the sunroof stops
moving.
2-50

Vent:The vent position allows you to open the rear
of the sunroof by tilting it upward. To use the vent
position, start with the sunroof in the fully closed
position, then press and hold the front side 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 side of the switch until the sunroof is fully
closed.
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.
To adjust the sunshade, pull it backward or forward to
the desired position. The sunshade can not be
closed further than the current closed position of the
sunroof.
Although the sunshade opens automatically when
opening the sunroof, it must be manually pulled closed
after closing the sunroof.
Vehicle Personalization
Memory Seat
If your vehicle has this
feature, the controls for the
memory function are
located on the driver’s door.
These buttons are used to program and recall memory
settings for the driver’s seat, both the driver’s and
passenger’s outside mirror, the radio station presets,
and the previously used climate control system settings.
The settings for these features can be personalized
for both driver 1 and driver 2. Driver 1 or driver 2
corresponds to the memory buttons labeled 1 and 2 on
the driver’s door and the numbers on the back of
the remote keyless entry transmitters.
