Fasten Safety Belt Indicator
The IPC illuminates the fasten safety belt indicator when the following
occurs:
| • | The inflatable restraint sensing and diagnostic module (SDM) detects
that the driver's seat belt is unbuckled. The IPC receives a class 2
message from the SDM requesting illumination. The IPC illuminates the
indicator for 20 seconds and then flashes the indicator for 55 seconds.
The IPC also sends a class 2 message to the radio in order to activate
the audible warning. |
| • | If the seat belt is unfastened and the indicator times out due
to shifting the vehicle into gear, then the indicator will be on for 20 seconds
and then the indicator will flash for 55 seconds. |
| • | If the driver unfastens the driver seat belt anytime during the
ignition cycle the telltale turns on for 20 seconds and followed by the indicator
flashing for 55 seconds. |
Restraint System
Seat belts are the primary means of occupant restraint. Seat belts help
to keep the occupant(s) inside the passenger compartment and to gradually
reduce the impact forces during the following events:
| • | Frontal impact type crashes |
| • | Rear impact type crashes |
| • | Side impact type crashes |
All seat belt retractors have emergency locks. The retractors remain
unlocked during normal operation and under normal driving conditions. The
retractors remain unlocked during normal conditions in order to allow
free movement of the upper body of each occupant. A pendulum locks the
seat belt webbing into position. The pendulum causes a locking bar to
engage a cog on the spool of the retractor mechanism when the following
conditions occur:
| • | A rapid extraction of the seat belt webbing from the retractor |
| • | An abrupt change in the vehicle speed |
| • | An abrupt change in the vehicle direction |
| • | Operation of the vehicle on a steep upgrade |
| • | Operation of the vehicle on a steep downgrade |
By pulling the shoulder belt the lap belt will tighten and hold until
unbuckled. This vehicle is also equipped with a supplemental inflatable
restraint (SIR) system. Refer to
SIR System Description and Operation
in SIR.
