^ THE BELT AND BUCKLE ASSEMBLY PRETENSIONER IS A PYROTECHNIC DEVICE. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING AN AIR BAG-EQUIPPED VEHICLE AND WHEN HANDLING A BELT AND BUCKLE ASSEMBLY PRETENSIONER. THIS WILL REDUCE THE RISK OF INJURY IN THE EVENT OF AN ACCIDENTAL DEPLOYMENT.
^ THE BELT AND BUCKLE ASSEMBLY PRETENSIONER IS A PYROTECHNIC DEVICE. NEVER PROBE THE CONNECTORS ON A PYROTECHNIC DEVICE. DOING SO COULD RESULT IN BELT AND BUCKLE ASSEMBLY PRETENSIONER OR AIR BAG DEPLOYMENT AND COULD RESULT IN PERSONAL INJURY.
^ TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY FRONT OR SIDE AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS AND BEFORE SERVICING, REPLACING, ADJUSTING OR STRIKING COMPONENTS NEAR THE FRONT OR SIDE AIR BAG SENSORS, SUCH AS DOORS, INSTRUMENT PANEL, CONSOLE, DOOR LATCHES, STRIKERS, SEATS AND HOOD LATCHES.
PLEASE REFER TO THE APPROPRIATE COMPONENT OR SYSTEM TO DETERMINE LOCATION OF THE FRONT AIR BAG SENSORS.
THE SIDE AIR BAG SENSORS ARE LOCATED AT OR NEAR THE BASE OF THE B-PILLAR.
TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT AT LEAST ONE MINUTE. BE SURE TO DISCONNECT AUXILIARY BATTERIES AND POWER SUPPLIES (IF EQUIPPED).
^ THE RESTRAINT SYSTEM DIAGNOSTIC TOOL IS FOR RESTRAINT SYSTEM SERVICE ONLY. REMOVE FROM VEHICLE PRIOR TO ROAD USE. FAILURE TO REMOVE COULD RESULT IN INJURY AND POSSIBLE VIOLATION OF VEHICLE SAFETY STANDARDS.
NOTE:
^ If a seat equipped with a seat mounted side airbag and/or a safety belt pretensioner (if equipped) system is being serviced the airbag system must be deactivated.
^ Restraint system diagnostic tools MUST be installed under the seats in the side airbag and safety belt pretensioner (if equipped) to floor connectors.
^ Diagnostics or repairs are not to be performed on a side airbag system and/or a safety belt pretensioner (if equipped) system with the seats in the vehicle. Prior to attempting to diagnose/repair the side airbag system and/or a safety belt pretensioner (if equipped) system the seats must be removed from the vehicle and the restraint system diagnostic tools must be installed in the side airbag and the safety belt pretensioner (if equipped) connectors at the floor connectors. The restraint system diagnostic tools must be removed prior to operating the vehicle over the road.
^ Diagnostics may be performed on seat systems other than the side airbag or the safety belt pretensioner (if equipped) system (lumbar, climate controlled, heated, power seat track) with the seat installed in the vehicle as long as the restraint system diagnostic tools are installed under the seats in the side airbag and safety belt pretensioner to floor connectors.
^ After diagnosing/repairing a seat system the restraint system diagnostic tools must be removed before operating the vehicle over the road.
^ Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.
1. Disconnect the battery ground cable and wait at least one minute.
