Programming the HomeLinkž
Transmitter
Do not use the HomeLinkžTransmitter with any garage
door opener that does not have the ªstop and reverseº
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
žTransmitter.
Read the instructions completely before attempting to
program the HomeLink
žTransmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
žprogramming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
žbuttons should be erased
for security purposes. Refer to ªErasing HomeLinkž
Buttonsº or, for assistance, contact HomeLinkžon the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
¯ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
žbuttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
ž
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
žand the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in ªGate Operator and Canadian
Programmingº later in this section.
4. The indicator light will ¯ash slowly at ®rst and then
rapidly after HomeLink
žsuccessfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
žbutton
and observe the indicator light.

Luggage Carrier
You can load things on top of your vehicle with this
feature.
The luggage carrier has slats and siderails attached to
the roof and crossrails which can be moved back
and forth to help secure cargo. Tie the load to the
siderails or siderail supports.
Notice:Loading cargo that weighs more than 200
lbs. (91 kg) on the luggage carrier may damage your
vehicle. When you carry large things, never let
them hang over the rear or the sides of your vehicle.
Load your cargo so that it rests on the slats and
does not scratch or damage the vehicle. Put
the cargo against the side rails and fasten it
securely to the luggage carrier. Put the main weight
as far forward as you can.
Don't exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see
Loading Your Vehicle on
page 4-51.
To prevent damage or loss of cargo as you're 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 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.
·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 rear glass.
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 is equipped with a rear armrest/cupholder
for the rear seat passengers.
To open it, pull up and then out on the tab, located at
the top center of the armrest, and pull the armrest down.
Cargo Cover Panels
{CAUTION:
Improperly stored cargo cover panels could be
thrown about the vehicle during a collision or
sudden maneuver. You or others could be
injured. If you remove a panel, always store it
in the proper storage location. When you put it
back, always be sure that is securely
reattached.
Notice:Each cargo cover is designed to support
250 lbs. (113 kg) on top of them. Exceeding the
weight limit can damage the cargo covers. This
damage would not be covered by your vehicle's
warranty.
Your vehicle may be equipped with a three-piece cargo
cover system. The cargo panels can be removed
and stored in the cargo area of the vehicle with the
cargo panel storage bag.
2-61

Cargo Panel Storage System
The three cargo panels can be stored on either the
driver's or passenger's side of the cargo box using the
storage bag. To store the panels, do the following:1. Secure the storage bag
in the cargo storage
area by attaching
the four clips on the
cargo bag to the
tie-down locations on
either side of the
storage area.
It is very important that you use the storage bag to
restrain the cargo panels during driving.
Before storing the cargo panels, be sure that the
latches are in the closed (locked) position. The
latches are in the closed (locked) position when they
are parallel to the front and back edge of the
panel.
2-64

6. Tighten both straps on the bag by pulling on the
free end of the straps.7. Close both top and bottom mechanisms at the
center of the bag (bag should now be tightly
secured).
2-67

7. Push the latches away from you (start with the left
latch) to lock the panel in place. You should hear a
click when each latch locks correctly.
Cargo Tie Downs
There are eight cargo tie downs in the rear cargo area.
You can use these to strap cargo in.
The tie downs are also used to secure the cargo cover
panel storage bag or the tonneau cover storage bag
if your vehicle is equipped with either. For more
information see ªCargo Cover Panelsº earlier in this
section and
Tonneau Cover on page 2-77.
2-71

Top-Box Storage
Your vehicle is equipped with top-box storage units on
both side of the vehicle. The passenger side top box
contains the tools you will need to change a ¯at tire.
Use the ignition/door key to unlock the top box lid if it is
locked. Press the key cylinder button and swing the
lid open. Turn on the cargo lamps if you need more light
inside the Top Boxes. See ªCargo Lampsº under
Exterior Lamps on page 3-13for more information on
cargo lamps. Use the ignition/door key to lock the
top boxes.
Tonneau Cover
{CAUTION:
Improperly stored tonneau cover components
could be thrown about the vehicle during a
collision or sudden maneuver. You or others
could be injured. If you remove the cover,
bows and rails, always store them properly in
the cargo area.
When you put them back, always be sure that
they are securely reattached.
2-77

5. Stow both bows and the front and rear rails in the
storage bag as shown. When all components of the
tonneau cover are secured in the bag properly,
zip the bag shut.
Reverse the procedure to reinstall the tonneau cover
using the following suggestions:
·When reinstalling the front rail, start by holding the
back edge of the rail (edge nearest you) up and
then twisting the back edge down while pushing it
into place.
·Both bows are the same size and therefore
interchangeable.
·When placing the bows in the side rails, it is easiest
to place the spring-loaded bow end in ®rst.
·When placing the bows,
locate the small notches
(arrow) in the side
rails. These notches
receive the tang on the
bow ends and help
the bows seat into
place.
·When reinstalling the tonneau cover, start at the
front, near the cab. Place the plastic lip into the
front rail, then the rear rail, and ®nish with the side
rails.
To clean the tonneau cover, use mild soap and water. If
necessary, use a soft bristle brush to remove dirt
trapped in the grain of the material.
