Pregnant women should always wear their
seatbelt. Position the lap belt portion of a
combination lap and shoulder belt low
across the hips below the belly and worn
as tight as comfort allows. Position the
shoulder belt to cross the middle of the
shoulder and the center of the chest.
Seatbelt Locking Modes
WARNING: If your vehicle is
involved in a crash, have the seatbelts
and associated components inspected
as soon as possible. Failure to follow this
instruction could result in personal injury
or death.
All safety restraints in the vehicle are
combination lap and shoulder belts and
have vehicle sensitive locking mode. In
addition, the front outboard passenger and
rear seat seatbelts have the automatic
locking mode.
Vehicle Sensitive Mode
This is the normal retractor mode, which
allows free shoulder belt length
adjustment to your movements and
locking in response to vehicle movement.
For example, if the driver brakes suddenly
or turns a corner sharply, or the vehicle
receives an impact of about
5 mph
(8 km/h) or more, the combination
seatbelts lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock
if you pull the webbing out too quickly. If
the seatbelt retractor locks, slowly lower
the height adjuster to allow the seatbelt
to retract. If the retractor does not unlock,
pull the seatbelt out slowly then feed a small length of webbing back toward the
stowed position. For rear seatbelts, recline
the rear seat backrest or push the seat
backrest cushion away from the seatbelt.
Feed a small length of webbing back
toward the stowed position.
Automatic Locking Mode
In this mode, the shoulder belt
automatically pre-locks. The belt still
retracts to remove any slack in the
shoulder belt. The automatic locking mode
is not available on the driver seatbelt.
When to Use the Automatic Locking
Mode
Use this mode any time a child safety seat,
except a booster, is installed in passenger
front or rear seating positions. Properly
restrain children 12 years old and under in
a rear seating position whenever possible.
See
Child Safety (page 25).
How to Disengage the Automatic
Locking Mode
Unbuckle the combination lap and
shoulder belt and allow it to retract
completely to disengage the automatic
locking mode and activate the vehicle
sensitive (emergency) locking mode.

The front passenger sensing system uses
a passenger airbag status indicator that
illuminates indicating that the front
passenger frontal airbag is either on
(enabled) or off (disabled).
The indicators are on the overhead
console.
Note:
The passenger airbag status indicator
lamps illuminate for a short period of time
when you first switch the ignition on to
confirm it is functional.
The front passenger sensing system is
designed to disable (will not inflate) the
front passenger frontal airbag when the
front passenger seat is unoccupied, or a
rear facing infant seat, a forward-facing
child restraint, or a booster seat is
detected. Even with this technology,
parents are strongly encouraged to
always properly restrain children in the rear
seat. •
When the front passenger sensing
system disables (will not inflate) the
front passenger frontal airbag, the
passenger airbag status indicator
illuminates the off lamp and stays lit
to remind you that the front passenger
frontal airbag is disabled.
• If you install the child restraint and the
passenger airbag status indicator
illuminates the on lamp, switch the
vehicle off, remove the child restraint
from the vehicle and reinstall the
restraint following the child restraint
manufacturer's instructions.
The front passenger sensing system is
designed to enable (may inflate) the front
passenger frontal airbag anytime the
system senses that a person of adult size
is sitting properly in the front passenger
seat.
• When the front passenger sensing
system enables the front passenger
frontal airbag (may inflate), the
passenger airbag status indicator
illuminates the on lamp and remains
illuminated.
If a person of adult size is sitting in the front
passenger seat, but the airbag off indicator
lamp is lit, it is possible that the person is
not sitting properly in the seat. If this
happens:
• Switch the vehicle off and ask the
person to place the seat backrest in an
upright position.
• Have the person sit upright in the seat,
centered on the seat cushion, with the
person ’s legs comfortably extended.
• Restart the vehicle and have the person
remain in this position for about two
minutes. This allows the system to
detect that person and enables (may
inflate) the passenger frontal airbag.
• If the indicator off lamp remains lit
even after this, advise the person to
ride in the rear seat.

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or adding
equipment to the front end of your
vehicle (including hood, bumper system,
frame, front end body structure, tow
hooks and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not
modify or add equipment to the front
end of your vehicle.
Your vehicle has a collection of crash and
occupant sensors which provide
information to the restraints control
module. The restraints control module
deploys (activates) the front seatbelt
pretensioners, driver airbag, passenger
airbag, knee airbag(s), seat mounted side
airbags and Safety Canopy airbags. Based
on the type of crash, the restraints control
module will deploy the appropriate safety
devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following: The readiness light will not
illuminate immediately after you
switch the ignition on. •
The readiness light either flashes or
stays lit.
• You will hear a series of five beeps. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The seatbelt pretensioners and the front
airbag supplemental restraint system are
designed to activate when the vehicle
sustains frontal deceleration sufficient to
cause the restraints control module to
deploy a safety device.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts unless the crash causes
sufficient frontal deceleration).
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal, side crashes and rollovers.
