²There are also pinch sensors attached to the side of the
liftgate. Light pressure anywhere along these strips
will cause the liftgate to return to the open position.
²The liftgate must be in the full open position in order
to power close. If the liftgate is not fully open, press
the power button to fully open the liftgate and then
you can press the power button to close.
²If the liftgate release switch is activated while the
power liftgate is closing, the liftgate will reverse to the
full open position.
²The power liftgate switches will not operate if the
vehicle is in gear or the vehicle speed is above 0 mph
(0 km/h).
²The power liftgate will not operate in temperatures
below212ÉF(224É C) or temperatures above 143É F(62É C). Be sure to remove any build-up of snow or ice
from the liftgate before pressing any of the power
liftgate switches.
²If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and must be opened or closed manually.
WARNING!
²Driving with the liftgate open can allow poison-
ous exhaust gases into your vehicle. You and your
passengers could be injured by these fumes. Keep
the liftgate closed when you are operating the
vehicle.
²If you are required to drive with the liftgate open,
make sure that all windows are closed, and the
climate control blower switch is set at high speed.
DO NOT use the recirculation mode.

WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you have
airbags.
²Being too close to the steering wheel or instrument
panel during front airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
²If the vehicle has left and right window bags, they
also need room to inflate. Do not lean against the
door or window. Sit upright in the center of the
seat.ªThe Airbag Systemº consists of the following:

How The Airbag System Works
²
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines theproper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
²The ORC will not detect side, roll over, or rear impacts.
²The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, instrument panel and passenger knee bol-
sters. If the key is in the OFF position, in the ACC
position, or not in the ignition, the airbags are not on
and will not inflate.
²Also, the ORC turns on the AIRBAG warn-
ing light and PAD indicator light in the
center of the instrument panel for 6 to 8
seconds for a self-check when the ignition is
first turned on. After the self-check, the AIRBAG
warning light will turn off. If equipped, the PAD
indicator light will function normally. If the ORC
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

detects a malfunction in any part of the system, it turns
on the AIRBAG warning light either momentarily or
continuously. A single chime will sound if the light
comes on again after initial start up.
WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won't have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked right
away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity ofnontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be possible based
on collision severity. The steering wheel hub trim
cover and the upper right side of the instrument panel
separate and fold out of the way as the airbags inflate
to their full size. The airbags fully inflate in about
50±70 milliseconds. This is about half of the time it
takes to blink your eyes. The airbags then quickly
deflate while helping to restrain the driver and front
passenger.
The driver's and passenger's front airbag gas is vented
through the airbag material towards the instrument
panel. In this way the airbags do not interfere with
your control of the vehicle.²TheSide Airbag Inflatable Curtainsare designed to
activate only in certain side collisions. When the ORC
and the side impact sensors (with side impact option)
detects a collision requiring the window bags to
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in
about 30 milliseconds (about one quarter of the time it
takes to blink your eyes) with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the window bag
inflates. This especially applies to children. The win-
dow bag is only about 3
1¤2inches (9 cm) thick when it
is inflated.
²When the ORC and the impact sensors detect a
collision requiring theDriver Inflatable Knee Blocker
Ð If Equipped,signals the inflator unit. A quantity of
nontoxic gas is generated to inflate the Driver Inflat-
able Knee Blocker. The Driver Inflatable Knee Blocker
inflates rearward towards the driver's knees to helpprotect the knees and position you for the best inter-
action with the front airbag. The Driver Inflatable
Knee Blocker fully inflates in about 50 milliseconds,
this is only about half of the time it takes you to blink
your eyes. It then quickly deflates while helping to
protect the driver's knees.
²TheKnee Impact Bolstershelp protect the knees, and
position everyone for the best interaction with the
front airbag.
²If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with theOccupant
Classification System (OCS).The OCS system will
classify an occupant into a size category based on
sensor readings from within the seat cushion. Occu-
pants should try to remain in a normally seated
position. If the occupant's weight is transferred to

For almost all sizes of properly seated adults, the airbag
will be enabled in the event of a collision. For small
teenagers and some small adults, depending on size, the
airbag may or may not be enabled in the event of a
collision. Both drivers and passengers should always use
the PAD indicator light as an indication if the frontpassenger is properly positioned or not. If the PAD
indicator light comes on when an adult is in the passen-
ger seat, have the passenger re-position themselves in the
seat until the light goes out.
Remember, if the PAD indicator light is illuminated the
passenger front airbag will not inflate. For properly
installed child restraint systems and children properly
seated on the front passenger seat, the airbag will be
disabled. If at all possible, place children 12 years and
younger in a back seat.
²TheOccupant Classification Module (OCM) Ð If
Equippedis located beneath the front passenger seat.
The OCM classifies the occupant into one of three size
categories based on the input from the Bladder Assem-
bly and Belt Tension Sensor. The size categories in-
clude empty, child, and adult. The OCM sends the
Occupant Classification to the ORC to identify if a
Passenger Airbag Light Ð If OCS Equipped
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

front passenger airbag is allowed. If a fault is present,
the AIRBAG warning light is illuminated.
²ThePassenger Airbag Disabled (PAD) Indicator
Light Ð If Equippedindicates to the driver and
passenger when the airbag is turned OFF in the
presence of a properly seated occupant. When the PAD
indicator light is illuminated, the airbag is OFF. Also,
when the Occupant Classification System (OCS) de-
tects either an empty seat of a weight less than the
predetermined occupant threshold, the ORC will not
illuminate the PAD indicator light even though the
airbag is turned off. When the OCS detects an adult
the PAD indicator light will be off, and the airbag will
be enabled.
²TheBelt Tension Sensor (BTS) Ð If Equippedis
located at the outboard passenger lap belt anchor. The
BTS generates a signal based on outboard lap belt
tension. This signal is sent to the OCM to ensure thatthe resultant bladder pressure increase due to applied
lap belt tension does not cause a small occupant to be
classified as a larger occupant.
²TheBladder Assembly Ð If Equippedis located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the ORC and impact sensors detect a moderate-to-
severe collision, to help restrain the vehicle passengers,
and then immediately deflate.
NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
²The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. 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
immediately.
²As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer's instruc-
tions for cleaning.
²It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
