Determining if the Personal Safety Systemா is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning lights and chimes section in the Instrument Cluster
chapter. Routine maintenance of the Personal Safety System is not
required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. In addition, the RCM also monitors the restraints
warning light in the instrument cluster. A difficulty with the system is
indicated by one or more of the following:
• The warning light will either flash or stay lit.
• The warning light will not illuminate immediately after the ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety restraints precautions
WARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING: To reduce the risk of injury, make sure children sit
in a rear seating position where they can be properly restrained.
WARNING: Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the
child from injury in a collision.
