Home Remote programming. It is also
recommended that upon the sale of the vehicle,
the programmed Universal Home Remote buttons
should be erased for security purposes. See

Storage Areas
Glove Box
Open the glove box by pulling the bottom of the
handle upward.
Cupholder(s)
Your vehicle may have cupholders located in the
front and rear of the oor console or in the fold
down armrest. The front cupholders can be
adjusted by moving the insert forward or rearward.
You may also have cupholders in the second and
third row seat armrest areas.
To access the cupholders in the rear oor console,
pull downward on the lid.
174

Center Console Storage Area
Your vehicle may have a console compartment
with cupholders between the bucket seats.
To open it, press the button and lift the console
lid open.
The rear of the console has a cupholder that
swings down for the rear seat passenger to use.
Luggage Carrier
If you have the luggage carrier, you can load
things on top of your vehicle.
The luggage carrier has siderails attached to the
roof and crossrails, if equipped, which can be
moved back and forth to help secure cargo. Tie the
load to the siderails or siderail supports.
Notice:Loading cargo on the luggage carrier
that weighs more than 200 lbs (91 kg) or
hangs over the rear or sides of the vehicle
may damage your vehicle. Load cargo so that
it rests as far forward as possible and
against the side rails, 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 Your
Vehicle on page 390.
To prevent damage or loss of cargo as you are
leaving, check now and then to make sure
the luggage and cargo are still securely fastened.
Be sure the cargo is properly loaded.
If small heavy objects are placed on the roof,
place the load in the area over the rear wheels
(behind the rear side door on extended
models). If you need to, cut a piece of 3/8 inch
plywood to t inside the crossrails and siderails
to spread the load. If plywood is used, tie it to
the siderail supports.
Tie the load to the crossrails or the siderail
supports. Use the crossrails only to keep the
load from sliding. To move the crossrails, pull
out on the latch release handle at each end.
Slide the crossrail to the desired position
balancing the force side to side. Push the
release handle back into the latched position
and slide the crossrail back and forth slightly to
be sure the latch snaps securely into place.
175

If you need to carry long items, move the
crossrails as far apart as they will go. Tie the
load to the crossrails and the siderails or
siderail supports. Also tie the load to the
bumpers. 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.
Your vehicle has a Center High-Mounted Stoplamp
(CHMSL) located above the glass or above the
rear load doors.
If items are loaded on the roof of the vehicle, care
should be taken not to block or damage the
CHMSL unit.
Rear Storage Area
Your vehicle may have a storage compartment
located in the rear cargo area of the vehicle in the
driver’s side trim panel.
To open the utility compartment, turn the knobs
and swing the compartment door open. The
compartment door can be removed.
Rear Seat Armrest
Your vehicle may be equipped with a rear seat
armrest. Pull the loop at the top of the armrest
down to access the cupholders.
