Airbag System
Your vehicle has a frontal airbag for the driver and
a frontal airbag for the right front passenger.
Your vehicle may also have side impact airbags.
Side impact airbags are available for the driver, the
right front passenger and the second row
captain’s chairs (if equipped).
If your vehicle has a side impact airbag, the word
AIRBAG will appear on the airbag covering on
the side of the seatback closest to the door.
Frontal airbags are designed to help reduce the
risk of injury from the force of an inating
frontal airbag. But these airbags must inate very
quickly to do their job and comply with federal
regulations.Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a
crash if you are not wearing your safety
belt — even if you have airbags. Wearing
your safety belt during a crash helps
reduce your chance of hitting things
inside the vehicle or being ejected from it.
Airbags are “supplemental restraints” to
the safety belts. All airbags are designed
to work with safety belts but do not
replace them.
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear crashes, or in many side
CAUTION: (Continued)

CAUTION: (Continued)
crashes. And, for some unrestrained
occupants, frontal airbags may provide
less protection in frontal crashes than
more forceful airbags have provided
in the past.
Side impact airbags are designed to
inate in moderate to severe crashes
where something hits the side of your
vehicle. They are not designed to inate in
frontal, in rollover, or in rear crashes.
Everyone in your vehicle should wear a
safety belt properly — whether or not
there is an airbag for that person.
{CAUTION:
Both frontal and side impact airbags
inate with great force, faster than the
blink of an eye. If you are too close to an
inating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag ination before and
during a crash. Always wear your safety
belt even with frontal airbags. The driver
should sit as far back as possible while
still maintaining control of the vehicle.
Occupants should not lean on or sleep
against the door.
77

{CAUTION:
If something is between an occupant and
an airbag, the airbag might not inate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inating airbag must
be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering. Do not let seat
covers block the ination path of a side
impact airbag.
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.
81

In addition, your vehicle has “dual stage” frontal
airbags, which adjust the restraint according
to crash severity. For moderate frontal impacts,
these airbags inate at a level less than full
deployment. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. For more severe frontal
impacts, full deployment occurs. 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 18 mph
(19 to 29 km/h), and the threshold level for
a full deployment is about 18 to 25 mph
(29 to 40.2 km/h). 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.
The frontal airbags (driver and right front
passenger) are not intended to inate during
vehicle rollovers, rear impacts, or in many side
impacts.
82

How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact the
steering wheel or the instrument panel. In
moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.
Airbags supplement the protection provided
by safety belts. Airbags distribute the force of the
impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But
the frontal airbags would not help you in many
types of collisions, including rollovers, rear
impacts, and many side impacts, primarily because
an occupant’s motion is not toward the airbag.
Side impact airbags would not help you in many
types of collisions, including many frontal or
near frontal collisions, rollovers, and rear impacts.
Airbags should never be regarded as anything
more than a supplement to safety belts, and then
only in moderate to severe frontal or near-frontal
collisions for the driver’s and right front
passenger’s frontal airbags, and only in moderate
to severe side collisions for vehicles with side
impact airbags.
What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so
quickly that some people may not even realize the
airbag inated. Some components of the airbag
module — the steering wheel hub for the driver’s
frontal airbag, the instrument panel for the
right front passenger’s frontal airbag, and for
seating positions with side impact airbags, the side
of the seatback closest to the door — may be
hot for a short time. The parts of the airbag that
come into contact with you may be warm, but
not too hot to touch. There may be some smoke
and dust coming from the vents in the deated
airbags. Airbag ination does not prevent the driver
from seeing out of the windshield or being able
to steer the vehicle, nor does it prevent people
from leaving the vehicle.
84

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety belt
system parts. If you see anything that might keep a
safety belt system from doing its job, have it
repaired. SeeCare of Safety Belts on page 490.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a
belt is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers,
and have them repaired or replaced. The airbag
system does not need regular maintenance.Notice:If you damage the covering for the
driver’s or the right front passenger’s frontal
airbag, or an airbag covering (if equipped) on a
seatback, the airbag may not work properly.
You may have to replace the airbag module in
the steering wheel, both the airbag module and
the instrument panel for the right front
passenger’s frontal airbag, or both the airbag
module and the seatback for seating positions
with a side impact airbag (if equipped.) Do not
open or break the airbag coverings.

Remote Power Sliding Door Operation
+
(Power Sliding Door):If your vehicle
has one power sliding door, the remote keyless
entry transmitter will have a button with a van
symbol on it. Press and hold this button to open or
close the power sliding door. SeePower Sliding
Door (PSD) on page 112.
*+(Dual Power Sliding Doors):If your
vehicle has dual power sliding doors, your remote
keyless entry transmitter will have two buttons
that have a van symbol on them. The van symbol
on the left is for the driver’s side sliding door
and the van symbol on the right is for the
passenger’s side sliding door. Press and hold the
passenger’s or driver’s side button, with the
van symbol on it, to open or close the selected
power sliding door. SeePower Sliding Door (PSD)
on page 112.You can operate the power sliding door(s) with the
remote keyless entry transmitter even if the
power sliding door override switch(es), on the
overhead console, are active or inactive.
SeePower Sliding Door (PSD) on page 112for
additional information.
If the sliding door is closed and the power sliding
door button on the transmitter is pressed and
held, the vehicle’s doors will be unlocked and then
the power sliding door will open. If the power
sliding door has been locked using the manual
door lock lever, you will need to unlock the power
sliding door before it can be opened with the
remote keyless entry transmitter sliding door
button.
If your vehicle’s fuel ller door is opened, the
driver’s side power sliding door will not open
completely. Do not try to force the door. Once the
fuel ller door is closed, the driver’s side sliding
door can be opened normally.
101

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out of
amoving vehicle. When a door
islocked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
CAUTION: (Continued)

Young children who get into unlocked
vehicles may be unable to get out. A
child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke.
Always lock your vehicle whenever
you leave it.
Outsiders can easily enter through an
unlocked door when you slow down
or stop your vehicle. Locking your
doors can help prevent this from
happening.
There are several ways to lock and unlock your
vehicle.
From the outside, use your key or the remote
keyless entry transmitter.
To unlock the driver’s door from the outside with
the key, insert the key and turn it toward the
front of the vehicle. To lock the driver’s door from
the outside with your key, insert the key and
turn it toward the rear of the vehicle.
106

Delayed Locking
This feature allows the locking of the vehicle to be
delayed until all doors have been closed for
approximately ve seconds.
To activate the delayed locking feature, do one of
the following:
Press the driver’s door power lock switch one
time while the driver’s door is open.
Press the passenger’s door power lock switch
one time while the passenger’s door is open.
Press the lock button on the remote keyless
entry transmitter one time while any door
is open.
Two chimes will sound to signal that delayed
locking is active.
The doors may be locked immediately by repeating
any of the above actions more than one time.If a door remains open, without any other door
being opened or closed, the vehicle will lock after
approximately 45 seconds.
If the key is in the ignition, this feature will not lock
the doors.
To turn the delayed locking feature off or on, see
DIC Vehicle Personalization (Uplevel Only) on
page 249.
Sliding Door Delayed Locking
If either sliding door is open when you use the
power door locks to lock the vehicle, the sliding
door that is open will not lock. Normally the
delayed locking feature will be used to lock the
sliding door after it has been closed.
The sliding door delayed locking feature will lock
your sliding door(s) in situations where the delayed
locking feature does not apply or was overridden
or programmed to be off. See “Delayed Locking”
earlier in this section. Shortly after the last
sliding door is closed, all the doors will lock.
