If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean something
is wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes causeabrasions and/or skin reddening to the
occupants as the air bags deploy and un-
fold. The abrasions are similar to friction
rope burns or those you might get sliding
along a carpet or gymnasium floor. They
are not caused by contact with chemicals.
They are not permanent and normally heal
quickly. However, if you haven’t healed
significantly within a few days, or if you
have any blistering, see your doctor imme-
diately.
• As the air bags deflate, you may see some smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may ir- ritate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irrita-
tion, move to fresh air. If the irritation
continues, see your doctor. If these par-
ticles settle on your clothing, follow the
garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well. NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be taken to an authorized dealer
immediately.
Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the batteryhas power or until the hazard light button
is pressed. The hazard lights can be deac-
tivated by pressing the hazard light but-
ton.
• Turn on the interior lights, which remain on as long as the battery has power.
• Unlock the power door locks.

tions below. See the section “Installing Child
Restraints Using the Vehicle Seat Belt” to
check what type of seat belt each seating
position has.
1. Loosen the adjusters on the lower strapsand on the tether strap of the child seat so
that you can more easily attach the hooks
or connectors to the vehicle anchorages.
2. Place the child seat between the lower anchorages for that seating position. For
some second row seats, you may need to
recline the seat and / or raise the head
restraint to get a better fit. If the rear seat
can be moved forward and rearward in the
vehicle, you may wish to move it to its
rear-most position to make room for the
child seat. You may also move the front
seat forward to allow more room for the
child seat.
3. Attach the lower hooks or connectors of the child restraint to the lower anchorages
in the selected seating position.
4. If the child restraint has a tether strap, connect it to the top tether anchorage. See the section “Installing Child Re-
straints Using the Top Tether Anchorage”
for directions to attach a tether anchor.
5. Tighten all of the straps as you push the child restraint rearward and downward
into the seat. Remove slack in the straps
according to the child restraint manufac-
turer’s instructions.
6. Test that the child restraint is installed tightly by pulling back and forth on the
child seat at the belt path. It should not
move more than 1 inch (25.4 mm) in any
direction.
How To Stow An Unused Switchable-ALR
(ALR) Seat Belt
When using the LATCH attaching system to
install a child restraint, stow all ALR seat
belts that are not being used by other occu-
pants or being used to secure child restraints.
An unused belt could injure a child if they
play with it and accidentally lock the seat belt
retractor. Before installing a child restraint
using the LATCH system, buckle the seat belt
behind the child restraint and out of the
child’s reach. If the buckled seat belt inter-
feres with the child restraint installation, instead of buckling it behind the child re-
straint, route the seat belt through the child
restraint belt path and then buckle it. Do not
lock the seat belt. Remind all children in the
vehicle that the seat belts are not toys and
that they should not play with them.
WARNING!
• Improper installation of a child restraint
to the LATCH anchorages can lead to
failure of the restraint. The child could
be badly injured or killed. Follow the
child restraint manufacturer’s directions
exactly when installing an infant or child
restraint.
• Child restraint anchorages are designed
to withstand only those loads imposed
by correctly-fitted child restraints. Un-
der no circumstances are they to be
used for adult seat belts, harnesses, or
for attaching other items or equipment
to the vehicle.
SAFETY

Installing Child Restraints Using The Ve-
hicle Seat Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
• Follow the child restraint manufacturer’s
directions exactly when installing an in-
fant or child restraint. The seat belts in the passenger seating posi-
tions are equipped with a Switchable Auto-
matic Locking Retractor (ALR) that is de-
signed to keep the lap portion of the seat belt
tight around the child restraint so that it is
not necessary to use a locking clip. The ALR
retractor can be “switched” into a locked
mode by pulling all of the webbing out of the
retractor and then letting the webbing retract
back into the retractor. If it is locked, the ALR
will make a clicking noise while the webbing
is pulled back into the retractor. Refer to the
“Automatic Locking Mode” description un-
der “Occupant Restraints” for additional in-
formation on ALR.

Installing A Child Restraint With A Switch-
able Automatic Locking Retractor (ALR)
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the
lap belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
• Follow the child restraint manufactur-
er’s directions exactly when installing an
infant or child restraint. 1. Place the child seat in the center of the
seating position.
2. Pull enough of the seat belt webbing from the retractor to pass it through the belt
path of the child restraint. Do not twist the
belt webbing in the belt path.
3. Slide the latch plate into the buckle until you hear a “click.”
4. Pull on the webbing to make the lap portion tight against the child seat.
5. To lock the seat belt, pull down on the shoulder part of the belt until you have
pulled all the seat belt webbing out of the
retractor. Then, allow the webbing to re-
tract back into the retractor. As the web-
bing retracts, you will hear a clicking
sound. This means the seat belt is now in
the Automatic Locking mode. 6. Try to pull the webbing out of the retractor.
If it is locked, you should not be able to
pull out any webbing. If the retractor is
not locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child
restraint while you push the child restraint
rearward and downward into the vehicle
seat.
8. If the child restraint has a top tether strap and the seating position has a top tether
anchorage, connect the tether strap to the
anchorage and tighten the tether strap.
