{CAUTION:
Anyone who is up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags 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 airbag
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,
seeOlder Children on page 1-26andInfants
and Young Children on page 1-28.
There is an airbag
readiness light on the
instrument panel, which
shows the airbag symbol.The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-26.Where Are the Airbags?
The driver’s airbag is in the middle of the steering wheel.

Programmable Automatic Door
Locks
Programmable automatic power door locks are intended
to provide enhanced security and convenience by
automatically locking and unlocking doors. This features
lets you program your power door locks to one of
four different modes.
Customizing the Automatic Door Locks
Mode 1:All doors automatically lock when the
transaxle is shifted out of PARK (P). The doors will
remain locked unless manually unlocked or the LOCK
button is pressed. All doors will unlock when the
transaxle is shifted into PARK (P) and the key is turned
to OFF.
Mode 2:This mode is only available with the remote
keyless entry transmitter. All doors automatically lock
when the transaxle is shifted out of PARK (P). Automatic
driver’s door only unlock when the transaxle is shifted into
PARK (P) and the key is turned to OFF.
Mode 3:All doors automatically lock when the transaxle
is shifted out of PARK (P). No automatic door unlock.Mode 4:No automatic door lock or unlock.
Before your vehicle was shipped from the factory it was
programmed in Mode 1. To determine the current
mode of the vehicle or to change to a different mode,
do the following:
1. Ensure the shift lever is in PARK (P) and all doors
are fully closed throughout this procedure. Turn the
ignition to ON.
2. Press and hold LOCK on either power door lock
switch for 10 seconds. Release the switch when
you hear the chime.
3. Count the number of chimes you hear. The number
of chimes tells you which mode your vehicle is in.
You can change the mode by pressing and
holding LOCK on the power door lock switch
(two chimes for Mode 2, three chimes for Mode 3
and four chimes for Mode 4).
4. Repeat Step 2 until you hear the number of chimes
that matches the mode you want.
The mode you selected is now set.

Rear Door Security Locks
Your vehicle has rear door security locks that help
prevent passengers from opening the rear doors of
your vehicle from the inside.
The lever for this feature
is located on the inside
of the rear door.
To use the security locks, do the following:
1. Slide the lever up.
2. Close the door.
3. Do the same thing to the other rear door.The rear doors on your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open a rear door while the security lock is on, do
the following:
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you do not cancel the security lock feature, adults or
older children who ride in the rear won’t be able to
open the rear door from the inside. You should let adults
and older children know how these security locks
work, and how to cancel the locks.

the outside.
2. Slide the lever down.
3. Do the same to the other rear door.

Lockout Protection
Lockout protection is intended to provide additional
security and convenience. While any door is open and
the key is in the ignition, the doors cannot be locked
by using the power door locks.
To override this feature, while the key is in the ignition
and any door is open, press and hold down the
power door lock switch for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If the key is not in the ignition,
or if you use the manual door lock or the remote
keyless entry transmitter, you could still lock your key
inside your vehicle. Always remember to take your
key with you.
Trunk
To unlock the trunk from the outside, insert the key
and turn the trunk lock cylinder. When closing the trunk
lid, push the truck lid in the center to ensure that the
lock fully latches.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-25.

release button, located on
the lower left side of
the instrument panel, to
release the trunk lid.
The remote trunk release will only work when either
the ignition is off, or with the ignition in ON while either
the parking brake is engaged or the vehicle speed
is less than 2 mph (3 km/h).
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 on the trunk latch. This
handle will glow following exposure to light. Pull the
release handle up to open the trunk from the inside.
