Changes or modications to this system by other

®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you transition the key
to RUN, ACCESSORY or START from the
OFF position.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents
the vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
If the engine does not start and the security light
on the instrument panel comes on when trying
to start the vehicle, the key may have a damaged
transponder. Turn the ignition off and try again.
134

If the engine still does not start, and the key
appears to be undamaged, try another ignition key.
At this time, you may also want to check the fuse,
seeFuses and Circuit Breakers on page 540.Ifthe
engine still does not start with the other key, your
vehicle needs service. If your vehicle does start, the
rst key may be faulty. See your dealer who can
service the PASS-Key
®III+ to have a new key
made. In an emergency, contact Roadside
Assistance.
It is possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or
replacement key. Up to nine additional keys may
be programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or
do not operate, you must see your dealer or
a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the
system.To program the new additional key do the
following:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed and turn
it to the RUN position within ve seconds of
removing the original key.
5. The security light will turn off once the key
has been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.
If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer.
If you lose or damage your PASS-Key
®III+ key,
see your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.

other vehicles as well as for future Universal
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.
