To slide the crossrails to where you want them, pull up
on the lever on each side of the crossrail. This will
release the crossrail and allow you to slide it. When the

NOTICE:
Loading cargo that weighs more than 220 lbs.
(100 kg) on the luggage carrier may damage
your vehicle.
When you carry cargo on the luggage carrier of
a proper size and weight, put it on the slats, and
distribute the weight evenly. Then slide the
crossrail up against the rear of the load, to help
keep it from moving. You can then tie it down.
Cargo containers must be loaded on the
crossrails only.
Don't exceed the maximum vehicle capacity when loading
your vehicle. For more information on vehicle capacity
and loading, see ªLoading Your Vehicleº in the Index.To prevent damage or loss of cargo as you're driving,
check now and then to make sure the luggage carrier is
locked and cargo is still securely fastened.
When the luggage carrier is not in use, place the cross
rails at the following positions for wind noise reduction.
Place one cross rail at the rear most point of the vehicle
and the other above the opening of the rear door.
Ashtrays and Cigarette Lighter
The front ashtray is removable and fits into the
front cupholder.
NOTICE:
Don't put papers and other things that burn into
your ashtray. If you do, cigarettes or other smoking
materials could set them on fire, causing damage.
To remove the front ashtray, pull the covered bin out of
the cupholder.
To use the lighter, press it in all the way, and let go.
When it's ready, it will pop back out by itself.

2-63
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overload, damaging the
lighter and the heating element.
Sun Visors
To block out glare, you can pull the visor down. You can
also swing the visor from side
-to-side.
Illuminated Visor Vanity Mirror
Pull the sun visor down and lift the mirror cover to turn
on the lamps.
Accessory Inflator (If Equipped)
Your vehicle may be equipped with an air inflator
system. You can inflate things like basketballs and
bicycle tires. Also, you can use it to bring your tire
pressure up to the proper pressure. It is not designed to
inflate large objects which will require more than five
minutes to inflate, such as an air mattress.
The air inflator is located
in the rear compartment
on the passenger's side
of the vehicle behind an
access cover.
To remove the cover, pull the two tabs on the cover and
pull it off.

2-64
The air inflator kit is located in the glove compartment.
The kit includes a 22
-foot (6.7 m) hose with three
nozzle adapters.
To use the air inflator attach the appropriate nozzle
adapter to the end of the hose if required. Then attach
that end of the hose to the object you wish to inflate.
Attach the other end of the hose to the outlet.
Press and release the switch to turn the air inflator
on. The indicator light will remain on when the inflator
is running.
The system has an internal clock to prevent overheating.
The system will allow about five minutes of running
time, then the compressor will stop. The indicator light
will then begin to flash. When the indicator is off, the
inflator can be started again by pressing the switch. If
the compressor is still hot, it may only run for a short
time before shutting off again.Press and release the switch to turn the inflator off.
Place the inflator kit tools in the pouch and store it
properly. Remove the inflator hose from the outlet
during loading and unloading. Load leveling will not
function with the inflator hose attached to the inflator
outlet. See ªElectronically Controlled Air Suspension
Systemº in the Index.
To reinstall the cover, line up the tabs at the back of the
cover, put it in place and latch the tabs.
A continuous flashing indicator light may also indicate a
malfunction in the air suspension system. See
ªElectronically Controlled Air Suspension Systemº in
the Index.
CAUTION:
Inflating something too much can make it
explode, and you or others could be injured. Be
sure to read the inflator instructions, and inflate
any object only to its recommended pressure.

rear of the center console, and the third one is located in
the rear of the vehicle near the liftgate.
Remove the cover from the outlet to use the outlet.
Be sure to put the cover back on when not using the
accessory power outlet.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result in
blown vehicle or adaptor fuses. If you experience a
problem, see your dealer for additional information
on the accessory power outlets.NOTICE:

slowly (this may take up to 30 seconds), hold the
hand
-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the

-held
transmitter is not weak. If you still cannot program it,
move the hand
-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to ªTraining a Garage Door Opener with
Rolling Codesº later in this section or contact the
manufacturer of HomeLink at 1

Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to HomeLink, see ªProgramming the
HomeLink Transmitterº listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the ªLearnº or ªSmartº button on the garage
door opener motor head unit. The exact location and
color will vary by garage door opener brand. If you
have difficulty finding the ªLearnº or ªSmartº
button, refer to your garage door opener owner's
manual or contact the manufacturer of HomeLink at
1
-800-355-3515, or on the internet at
www.homelink.com. Because of the steps involved,
it may be helpful to have another person assist in
programming the transmitter.
2. Press the ªLearnº or ªSmartº button on the garage
door opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.

manufacturer of HomeLink at 1
-800-355-3515, or on
the internet at www.homelink.com.
