When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate to
severe frontal or near-frontal crashes. But they are
designed to inate only if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds take into account a variety of desired
deployment and non-deployment events and are
used to predict how severe a crash is likely to be in
time for the airbags to inate and help restrain the
occupants. Whether your frontal airbags will or
should deploy is not based on how fast your vehicle
is traveling. It depends largely on what you hit, the
direction of the impact, and how quickly your
vehicle slows down.
Your vehicle has a “dual stage” driver airbag,
which adjusts the restraint according to crash
severity using electronic frontal sensor(s) which
help the sensing system distinguish between
a moderate frontal impact and a more severe
frontal impact. The “dual stage” driver airbag
inates to a level less than full deployment for
moderate frontal impacts and to a full deployment
for more severe frontal impacts.Your vehicle has a “dual depth” passenger airbag
that adjusts the restraint according to crash
severity, seat location, and safety belt status using
electronic frontal sensor(s) and other special
sensors which enable the sensing system
to monitor the status of the front passenger safety
belt and the position of the front passenger
seat. The passenger airbag inates to a reduced
depth when the passenger seat is in a forward
position. For more rearward front seating positions,
the passenger airbag may inate to an increased
depth (a full deployment), based on safety
belt status and the crash severity measured early
in the event. Always wear your safety belt,
even with frontal airbags.
If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold
level for the reduced deployment is about 12 to
16 mph (19 to 26 km/h), and the threshold level for
a full deployment is about 17 to 23 mph (27 to
37 km/h) if the other sensors do not over-ride this.
The threshold level can vary, however, with
specic vehicle design, so that it can be somewhat
above or below this range.

Frontal airbags may inate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could inate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash
speed than if the vehicle hits an object that
does not deform.
If the vehicle hits a narrow object (like a pole),
the airbags could inate at a different crash
speed than if the vehicle hits a wide object
(like a wall).
If the vehicle goes into an object at an angle,
the airbags could inate at a different crash
speed than if the vehicle goes straight into the
object.
Frontal airbags (driver and right front passenger)
are not intended to inate during vehicle rollovers,
rear impacts, or in many side impacts.Your vehicle has sensors which enable the
sensing system to monitor the position of the right
front passenger’s seat, whether the occupant is
buckled or unbuckled. The passenger seat position
sensor and passenger safety belt buckle switch
provide information which is used to determine if
the airbags should deploy at a reduced level or full
deployment.
Side impact airbags are intended to inate in
moderate to severe side crashes. A side impact
airbag will inate if the crash severity is above the
system’s designed “threshold level.” The threshold
level can vary with specic vehicle design. Side
impact airbags are not intended to inate in many
frontal or near-frontal impacts, rollovers, or rear
impacts. Both roof-mounted side impact airbags will
deploy when either side of the vehicle is struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair
costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle of
the impact, and how quickly the vehicle slows
down. For side impact airbags, ination is
determined by the location and severity of the
impact.

The passenger sensing system will turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver’s airbags are not part of the
passenger sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger’s seat and
safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger’s frontal
airbag and seat-mounted side impact airbag should
be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal and
seat-mounted side impact airbag if the
system detects a rear-facing child
restraint, no system is fail-safe, and no
one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We
recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbags are off.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 482.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, overhead console, ceiling
headliner, ceiling and pillar garnish trim,
roof-mounted airbag modules, or airbag wiring
can affect the operation of the airbag
system. If you have questions, call Customer
Assistance. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 482.

Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades
become worn or damaged, replace with new
blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps.
After the windshield wipers have completed eight
wipe cycles within four minutes, the headlamps
automatically turn on. SeeWiper Activated
Headlamps on page 197for more information.Rainsense™ II Wipers
If your vehicle has this feature, the moisture
sensor is mounted on the interior side of the
windshield behind the rearview mirror. It is used
to automatically operate the wipers by monitoring
the amount of moisture build-up on the windshield.
Wipes occur as needed to clear the windshield
depending on driving conditions and the sensitivity
setting. In light rain or snow, fewer wipes will occur.
In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ II wipers operate in
a delay mode as well as a continuous low or high
speed as needed. If the system is left on for long
periods of time, occasional wipes may occur
without any moisture on the windshield. This is
normal and indicates that the Rainsense™ II
system is activated.
173

The Rainsense™ II system can be activated by
turning the wiper band to one of the ve sensitivity
levels indicated on the wiper stalk. The position
closest to off is the lowest sensitivity setting, level
one. This allows more rain or snow to collect on the
windshield between wipes. Turning the wiper band
away from you to higher sensitivity levels increases
the sensitivity of the system and frequency of
wipes. The highest sensitivity setting, level ve is
closest to low. A single wipe will occur each time
you turn the wiper stalk to a higher sensitivity level
to indicate that the sensitivity level has been
increased.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.The mist and wash cycles operate as normal and
are not affected by the Rainsense™ II function.
The Rainsense™ II system can be overridden at
any time by manually turning the wiper band to low
or high speed.
When Rainsense™ II is active, the headlamps
will turn on automatically. The headlamps will
turn off again once the wipers turn off if it is light
enough outside. If it is dark, they will remain
on. SeeWiper Activated Headlamps on page 197
for more information.
Notice:Do not place stickers or other items
on the exterior glass surface directly in front of
the moisture sensor. Doing this could cause
the moisture sensor to malfunction.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has this feature, be sure to read
this entire section before using it.
IntelliBeam™ is an enhancement to your vehicle’s
headlamp system. Using a digital light sensor
on your rearview mirror, this system turns
the vehicle’s high-beam headlamps on and
off according to surrounding traffic conditions.
The IntelliBeam™ system turns the high-beam
headlamps on when it is dark enough, there is no
other traffic present, and the IntelliBeam system
is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam™ button on
the inside rear view mirror. The IntelliBeam™
indicator on the mirror turns on to indicate
the system is on. Once the system has been
turned on, it remains on each time the vehicle
is started, but the IntelliBeam system must
be enabled.To enable the IntelliBeam™ system, turn the
exterior lamp control to AUTO, with the turn
signal/multifunction lever in its neutral position.
The High-Beam On Light appears on the
instrument panel cluster when the high-beams
are on. SeeHighbeam On Light on page 238.
Driving with IntelliBeam™
IntelliBeam™ only activates the high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps remain on, under the
automatic control of IntelliBeam™, until any of
the following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s
taillamps.
The outside light is bright enough that
high-beam headlamps are not required.
The vehicle’s speed drops below
15 mph (24 km/h).
194

The headlamp stalk is moved forward to the
high-beam position or the ash-to-pass feature
is used. SeeHeadlamp High/Low-Beam
Changer on page 167andFlash-to-Pass
on page 172.
When either of these conditions occur, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off until
the high-beam stalk is returned to the neutral
position.
If IntelliBeam™ was using low-beams prior
to this action, the IntelliBeam™ feature is
temporarily disabled until the stalk is returned
to the neutral position.
The exterior lamp control is turned to any
setting except AUTO.
When this occurs, IntelliBeam™ is disabled
until the control is turned back to the AUTO
position.
The IntelliBeam™ system is turned off at the
inside rearview mirror.IntelliBeam™ might not turn off the high-beams if
the system cannot detect other vehicle’s lamps
because of any of the following:
The other vehicle’s lamp(s) are missing,
damaged, obstructed from view, or otherwise
undetected.
The other vehicle’s lamp(s) are covered with
dirt, snow, and/or road spray.
The other vehicle’s lamp(s) cannot be detected
due to dense exhaust, smoke, fog, snow, road
spray, mist, or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view
of the IntelliBeam™ light sensor.
Your vehicle’s windshield is covered with ice,
dirt, haze, or other obstructions.
Your vehicle is loaded such that the front
end of the vehicle points upward, causing the
IntelliBeam™ sensor to aim high and not detect
headlamps and taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
