{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”There is an air bag readiness light on the instrument
panel, which shows the words AIR BAG or an air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAir Bag Readiness Light on page 3-50
for more information.United States

Section 2 Features and Controls

Programmable Automatic Door
Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have the person use the manual lever or
power door lock switch. When the door is closed again,
it will not lock automatically. Use the manual lever or
power door lock switch to lock the door.
With the vehicle in PARK (P) and the ignition in ON, the
door locks can be programmed through prompts
displayed on the Driver Information Center (DIC). These
prompts allow the driver to choose various lock and
unlock settings. For programming information, seeDIC
Vehicle Personalization on page 3-74.
Rear Door Security Locks
Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.
The rear door security
locks are located on the
edge of each rear
door. You must open the
doors to access them.
To use these locks, do the following:
1. Turn the knob located on the passenger’s side rear
door clockwise to engage the lock.
2. Close the door.
3. Turn the knob located on the driver’s side rear door
counterclockwise to engage the lock.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
2-10

When you want to open a rear door while the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the front door power lock switch or
by lifting the rear door manual lock.
2. Then open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Turn the knob on the passenger’s side of the rear
door counterclockwise all the way back to the
original position.
3. Turn the knob on the driver’s side of the rear door
clockwise all the way back to the original position.
The rear door locks will now work normally.Lockout Protection
Leaving your key in any ignition position with any door
open will disable the power door lock switches as
well as the lock button on the remote keyless entry
transmitter. If you close the doors, you can lock them
using the remote keyless entry transmitter. It is
always recommended that you remove the ignition key
when locking your vehicle.
The anti-lockout feature can be overridden by holding
the power door lock switch for three seconds or longer.
Leaving Your Vehicle
If you are leaving your vehicle, open the door, set the
locks from the inside, get out and close the door.

Trunk Lid Tie Down
{CAUTION:
Driving with the trunk lid open can allow
dangerous CO (carbon monoxide) gas to come
into your vehicle. You can not see or smell CO.
It can cause unconsciousness and even death.
If you ever need to drive with your trunk lid
open, then:
Make sure all windows, the rear seat
pass-through and sunroof are closed.
Turn the fan on your heating and cooling
system to its highest speed, with the
setting on AUTO and temperature between
65°F (18°C) and 85°F (29°C). This forces
fresh outside air into your vehicle.
Open all air ducts on the instrument panel.
Do not use the trunk lid tie down if you are
towing a trailer because of the danger of CO.Your vehicle may be equipped with a trunk-lid tie down.
This feature is used to secure the trunk lid if it will
not close completely, such as when carrying large
packages in the trunk. Use the following steps to secure
the trunk lid:
1. Attach the clip end of the tie down to the D ring on
the trunk lid (A).
2. Attach the hook end of the tie down to the striker
located at the center of the trunk sill (B).
3. Tighten the tie down by pulling the free end of the
cord until secure.
4. To remove the tie down, press the clip end release
and loosen the cord.

Emergency Trunk Release Handle
Notice:Using the emergency trunk release handle
as a tie-down or anchor point when securing
items in the trunk may damage it. Use the
emergency trunk release handle only to help you
open the trunk lid.
There is a glow-in-the-dark emergency trunk release
handle located inside the trunk near the latch. This
handle will glow following exposure to light. Pull
the release handle upward to open the trunk from the
inside.
Rear Seat Pass Through
Your vehicle may be equipped with a small door in the
rear seat. The door allows you to access the trunk
from inside the vehicle.
The rear-seat armrest must be down for the
pass-through door to open. To release the pass-through
door, move the release up with your ngers. Then
close the door so it latches from inside the vehicle.
2-14

To raise the power sunshade, press and release the
REAR SHADE switch located on the front overhead
console. To close the power sunshade, press and
release the REAR SHADE switch again.
Never store objects on the rear shelf because they may
get caught in the sunshade or be tossed about in
your vehicle.
Manual Rear Side Door Sunshade
Your vehicle may have manual rear side door
sunshades. To use the sunshades, lower the side
windows and hook the top edge of the retractable
sunshades over the edge of the windows and raise the
windows. To remove the shades, lower the windows
and the hooks will disengage automatically.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
The SECURITY light is
located on the instrument
panel cluster.
If the ignition is off and any door is open, the SECURITY
light will ash, reminding you to arm the system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the remote keyless entry
transmitter. The SECURITY light should come on
and stay on.
3. Close all the doors. The SECURITY light should go
off within approximately 30 seconds.
