152 SAFETY
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible.
Here are some simple steps you can take to
mi

nimize the risk of harm from a deploying air bag:

1. Children 12 years old and under should a
lways ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the
v
ehicle seat belt properly must be secured in
the appropriate child restraint or
belt-positioning booster seat in a rear seating
position
Ú page 166.
3. I f a child from 2 to 12 years old (not in a
r
ear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint
Ú page 166.
4. N ever allow children to slide the shoulder belt
b
ehind them or under their arm.
5. You should read the instructions provided with y
our child restraint to make sure that you are
using it properly.
6. A ll occupants should always wear their lap and
s
houlder belts properly. 7. T
he driver and front passenger seats should
b
e moved back as far as practical to allow the
front air bags room to inflate.
8. D o not lean against the door or window. If your
v
ehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between occupants and the
door and occupants could be injured.
9. I f the air bag system in this vehicle needs to be
m
odified to accommodate a disabled person,
see
Ú page 251 for customer service contact
information.
SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver,
even on short trips. Someone on the road may be
a poor driver and could cause a collision that
includes you. This can happen far away from home
or on your own street.
Research has shown that seat belts save lives, and
t h

ey can reduce the seriousness of injuries in a
collision. Some of the worst injuries happen when
people are thrown from the vehicle. Seat belts
reduce the possibility of ejection and the risk of
injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at all
times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver and Passenger BeltAlert (if equipped)
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
e q

uipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The BeltAlert
feature is active whenever the ignition switch is in
the START or ON/RUN position.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.

SAFETY 157
Seat Belts And Pregnant Women

Seat Belts and Pregnant Women

Seat belts must be worn by all occupants including
pr
egnant women: the risk of injury in the event of
an accident is reduced for the mother and the
unborn child if they are wearing a seat belt.
Position the lap belt snug and low below the
ab
domen and across the strong bones of the hips.
Place the shoulder belt across the chest and away
from the neck. Never place the shoulder belt
behind the back or under the arm.
Seat Belt Pretensioner
The front outboard seat belt system is equipped
with pretensioning devices that are designed to
remove slack from the seat belt in the event of a
collision. These devices may improve the
performance of the seat belt by removing slack from the seat belt early in a collision. Pretensioners
work for all size occupants, including those in child
restraints.
NOTE:
These devices are not a substitute for proper seat
b e
lt placement by the occupant. The seat belt still
must be worn snugly and positioned properly.
The pretensioners are triggered by the Occupant
R e

straint Controller (ORC). Like the air bags, the
pretensioners are single use items. A deployed
pretensioner or a deployed air bag must be
replaced immediately.
Energy Management Feature
The front outboard seat belt system is equipped
with an Energy Management feature that may help
further reduce the risk of injury in the event of a
collision. The seat belt system has a retractor
assembly that is designed to release webbing in a
controlled manner.
Switchable Automatic Locking Retractors
(ALR)
The seat belts in the passenger seating positions
are equipped with a Switchable Automatic Locking
Retractor (ALR) which is used to secure a child
restraint system
Ú page 173.
The figure below illustrates the locking feature for
e a

ch seating position.
ALR — Switchable Automatic Locking Retractor
If the passenger seating position is equipped with an
A L

R and is being used for normal usage, only pull the
seat belt webbing out far enough to comfortably
wrap around the occupant’s mid-section so as to not
activate the ALR. If the ALR is activated, you will hear
a clicking sound as the seat belt retracts. Allow the
webbing to retract completely in this case and then
carefully pull out only the amount of webbing
necessary to comfortably wrap around the
occupant’s mid-section. Slide the latch plate into the
buckle until you hear a "click."

In Automatic Locking Mode, the shoulder belt is
a u

tomatically pre-locked. The seat belt will still
retract to remove any slack in the shoulder belt.
Use the Automatic Locking Mode anytime a child
restraint is installed in a seating position that has
a seat belt with this feature. Children 12 years old
and under should always be properly restrained in
the rear seat of a vehicle with a rear seat.

158 SAFETY
How To Engage The Automatic Locking Mode

1. B uckle the combination lap and shoulder
b
elt.

2. Grab the shoulder portion and pull downward u
ntil the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt r
etracts, you will hear a clicking sound. This
indicates the seat belt is now in the Automatic
Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and
a l

low it to retract completely to disengage the
Automatic Locking Mode and activate the vehicle
sensitive (emergency) locking mode.
SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others. If
you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you in
a

collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the electrical Air Bag System Components. Your
vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
p
a
rts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the ignition switch is in the OFF position
or in the ACC position, the air bag system is not on
and the air bags will not inflate.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR)
feature or any other seat belt function is not
working properly when checked according to
the procedures in the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system
provides output appropriate to the severity and
type of collision as determined by the Occupant
Restraint Controller (ORC), which may receive
information from the front impact sensors (if
equipped) or other system components.The first stage inflator is triggered immediately
d
u

ring an impact that requires air bag deployment.
A low energy output is used in less severe
collisions. A higher energy output is used for more
severe collisions.

This vehicle may be equipped with a driver and/or
f r

ont passenger seat belt buckle switch that detects
whether the driver or front passenger seat belt is
buckled. The seat belt buckle switch may adjust the
inflation rate of the Advanced Front Air Bags.

This vehicle may be equipped with driver and/or
f r

ont passenger seat track position sensors that
may adjust the inflation rate of the Advanced Front
Air Bags based upon seat position.Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.
On the other hand, depending on the type and
l oc

ation of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
de
celeration over time, vehicle speed and damage
by themselves are not good indicators of whether
or not an air bag should have deployed.
WARNING!
Being too close to the steering wheel or instru -
ment panel during front air bag deployment
c ou
ld cause serious injury, including death. Air
bags need room to inflate. Sit back, comfort -
ably extending your arms to reach the steering
w h

eel or instrument panel.
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!
No objects should be placed over or near the
air bag on the instrument panel or steering
wheel because any such objects could cause
harm if the vehicle is in a collision severe
enough to cause the air bag to inflate.
Do not put anything on or around the air bag
covers or attempt to open them manually. You
may damage the air bags and you could be
injured because the air bags may no longer be
functional. The protective covers for the air
bag cushions are designed to open only when
the air bags are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.
WARNING!

SAFETY 161
Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
de

tects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.
The steering wheel hub trim cover and the upper
p a

ssenger side of the instrument panel separate
and fold out of the way as the air bags inflate to
their full size. The front air bags fully inflate in less
time than it takes to blink your eyes. The front air
bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column. The
Supplemental Driver Knee Air Bag provides
enhanced protection during a frontal impact by
working together with the seat belts,
pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental
S e

at-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs)
ar
e located in the outboard side of the front seats.
The SABs are marked with “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on the
outboard side of the seats.
The SABs may help to reduce the risk of occupant
i n

jury during certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.
Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the
ou t

board side of the seatback’s trim cover. The
inflating SAB deploys through the seat seam into
the space between the occupant and the door. The
SAB moves at a very high speed and with such a
high force that it could injure occupants if they are
not seated properly, or if items are positioned in
the area where the SAB inflates. Children are at an
even greater risk of injury from a deploying air bag.
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights, stereos,
citizen band radios, etc.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags; the
performance could be adversely affected and/or
objects could be pushed into you, causing
serious injury.

162 SAFETY
Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental Side
Ai

r Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains
(S
ABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”

Supplemental Side Air Bag Inflatable Curtain (SABIC) La

bel Location

SABICs may help reduce the risk of head and other
in
juries to front and rear seat outboard occupants
in certain side impacts, in addition to the injury
reduction potential provided by the seat belts and
body structure. The SABIC deploys downward, covering the side
w
i

ndows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers the
window. The SABICs inflate with enough force to
injure occupants if they are not belted and seated
properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag.
The SABICs may help reduce the risk of partial or
c om

plete ejection of vehicle occupants through
side windows in certain side impact events. Side Impacts
The Side Air Bags are designed to activate in
c
e

rtain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid
the ORC in determining the appropriate response
to impact events. The system is calibrated to
deploy the Side Air Bags on the impact side of the
vehicle during impacts that require Side Air Bag
occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact
deploys the left Side Air Bags only and a right-side
impact deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of whether
or not Side Air Bags should have deployed.
The Side Air Bags will not deploy in all side
c ol

lisions, including some collisions at certain
angles, or some side collisions that do not impact
the area of the passenger compartment. The Side
Air Bags may deploy during angled or offset frontal
collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt
r e

straint system. Side Air Bags deploy in less time
than it takes to blink your eyes.
WARNING!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended, do
not install any accessory items in your vehicle
which could alter the roof. Do not add an after -
market sunroof to your vehicle. Do not add
r oo

f racks that require permanent attach -
ments (bolts or screws) for installation on the
v e

hicle roof. Do not drill into the roof of the
vehicle for any reason.

SAFETY 163
(Continued)
NOTE:
Air bag covers may not be obvious in the interior
t r
im, but they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
d e

signed to activate in certain rollover events. The
Occupant Restraint Controller (ORC) determines
whether deployment in a particular rollover event
is appropriate, based on the severity and type of
collision. Vehicle damage by itself is not a good
indicator of whether or not Side Air Bags and seat
belt pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners will
n ot

deploy in all rollover events. The rollover
sensing system determines if a rollover event may
be in progress and whether deployment is
appropriate. In the event the vehicle experiences a
rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy
the Side Air Bags and seat belt pretensioners on
both sides of the vehicle. The SABICs may help reduce the risk of partial or
c
om

plete ejection of vehicle occupants through
side windows in certain rollover or side impact
events.

seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or area
where the side air bags inflate, even if they are
in an infant or child restraint.
Seat belts (and child restraints where appro -
priate) are necessary for your protection in all
c ol
lisions. They also help keep you in position,
away from an inflating Side Air Bag. To get the
best protection from the Side Air Bags, occu -
pants must wear their seat belts properly and
s i

t upright with their backs against the seats.
Children must be properly restrained in a child
restraint or booster seat that is appropriate for
the size of the child.
WARNING!
Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the
center of the seat.
Being too close to the Side Air Bags during
deployment could cause you to be severely
injured or killed.
Relying on the Side Air Bags alone could lead
to more severe injuries in a collision. The Side
Air Bags work with your seat belt to restrain
you properly. In some collisions, Side Air Bags
won’t deploy at all. Always wear your seat belt
even though you have Side Air Bags.
