Driver And Passenger
BeltAlert (If Equipped)
Seat Belt Warning Systems
The LED on dashboard trim turns on if
the driver or passenger's seat is
occupied and the seat belt is not
fastened with the ignition switched ON.
If the driver or passenger's seat belt is
unfastened (only when the passenger
seat is occupied) and the vehicle is
driven at a speed faster than about
12 MPH (20 km/h), the
LED flashes.
After a short time, the LED stops
flashing, but remains illuminated.
If a seat belt remains unfastened, the
LED flashes again for a given period of
time. In this case, fasten the seat belt.
Seat Belt Pretensioner
For optimum protection, the driver and
passenger seat belts are equipped with
pretensioner and load limiting systems.
For both these systems to work properly
you must wear the seat belt properly.
The seat belt pretensioners are
designed to deploy in moderate or
severe frontal, near frontal collisions. In
addition, during a side collision, the
pretensioner operates on the side in
which the collision occurs. The
pretensioners operate differently
depending on what types of air bags
are equipped. For details on the seat
belt pretensioner operation, refer to the
“SRS Air Bag Deployment Criteria”
paragraph in this chapter.
When a collision is detected, the
pretensioners deploy simultaneously
with the air bags. For deployment
details, refer to the “SRS Air Bag
Deployment Criteria” paragraph in this
chapter.
The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have fired they must be
replaced.
With Passenger Occupant
Classification System
In addition, the pretensioner system for
the passenger, like the front and side
passenger Air Bag, is designed to only
deploy when the passenger occupant
classification sensor detects a
passenger sitting on the passenger's
seat.
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 Restraint Controller
(ORC). Like the air bags, the
pretensioners are single use items. A
deployed pretensioner or a deployed
air bag must be replaced immediately.
Load Limiter
The load limiting system releases belt
webbing in a controlled manner to
reduce belt force on the occupant's
chest.
While the most severe load on a seat
belt occurs in frontal collisions, the load
limiter has an automatic mechanical
function and can activate in any
accident mode with sufficient occupant
movement.
Even if the pretensioners have not fired,
the load limiting function must be
checked by an authorized dealer.
