Seat Belt System Operation Description
Seat belts are the primary means of occupant restraint. Seat
belts help to keep the occupant inside the passenger compartment and also
help to ride down the crash forces more gradually during the following events:
• | Frontal impact type crashes. |
• | Rear impact type crashes. |
• | Side impact type crashes. |
• | Roll over type crashes. |
All seat belts have emergency locks in the retractors. During normal
operation, the retractors remain unlocked to allow free movement of the occupant's
upper body under normal driving conditions. The seat belt webbing is locked
into position by a pendulum that causes a locking bar to engage a cog on
the spool of the retractor mechanism under the following conditions:
• | Rapid extraction of the seat belt webbing from the retractor. |
• | The speed of the vehicle changes abruptly. |
• | The direction of the vehicle changes abruptly. |
• | The vehicle is on a steep upgrade or a downgrade. |
In conjunction with the seat belts, this vehicle is equipped with a
Supplemental Inflatable Restraint (SIR) System. Refer to
SIR Diagnostic System Check
in SIR.
Seat Belt System Operation Police Package
Police Package Pursuit Performance Safety Belt
A driver side safety belt with a locking lap retractor is available
as a dealer option. The purpose of this safety belt is to hold the officer
more securely in the seat during maneuvers associated with high speed pursuits.
To activate the system, buckle the belt as normal and then pull out all of
the lap belt webbing. This activates a mechanism that puts the lap retractor
into an automatic locking mode. Once in this mode the belt can be tightened
by pulling the belt toward the retractor to return any slack. To deactivate
the mechanism unbuckle the safety belt and let all of the lap belt webbing
return to the retractor.
The mechanism in this optional belt is similar to that already installed
on the passenger side lap belt and in both outboard rear seat safety belts.
The feature was added to these other locations to allow a child restraint
to be properly secured in the vehicle. See the Owner's Manual for further
information.
