Seat Belt Pretensioners
The seat belts for both front seating positions are
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 assuring that the belt is tight about the occupant
early in a collision. Pretensioners work for all size occu-
pants, including those in child restraints.
NOTE: These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC). Like the air bags, the preten-
sioners are single use items. A deployed pretensioner or
a deployed air bag must be replaced immediately.
Enhanced Seat Belt Use Reminder System
(BeltAlert®)
BeltAlert® is a feature intended to remind the driver and
front passenger (if equipped with front passenger
BeltAlert®) to fasten their seat belts. The feature is active
whenever the ignition is on. If the driver or front seat
passenger is unbelted, the Seat Belt Reminder Light will
turn on and remain on until both front seat belts are
fastened.
The BeltAlert® warning sequence begins after the vehicle
speed is over 5 mph (8 km/h), by blinking the Seat Belt
Reminder Light and sounding an intermittent chime.
Once the sequence starts, it will continue for the entire
duration or until the respective seatbelts are fastened.
After the sequence completes, the Seat Belt Reminder
Light remains illuminated until the respective seat belts
are fastened. The driver should instruct all other occu-
pants to fasten their seat belts. If a front seat belt is
