INTRODUCTION - GENERAL RULES OF MAINTENANCE OPERATION 01-13

• Always confirm to turn off ignition switch to "LOCK" position, and don't carry out
the operation until 90s after disconnecting the battery positive and negative cable.
(The supplemental restraint system is configured with a backup power supply,
therefore if the operation is carried out within 90s after disconnecting the battery 01
positive and negative cable, it may cause the sudden expansion of air bag.
• After disconnecting the battery negative cable, the memory of electronic clock
and audio system will be cleared. All necessary data shall be recorded before
maintenance. At the end of maintenance, reset the audio system and adjust the
electronic clock. Never try to use the backup power supply outside of the vehicle,
so as to avoid the loss of data in each memory of system. The backup power
supply will supply power for the supplemental restraint system, it may cause a
sudden expansion of air bag at the time of maintenance.
• Even if the impact is very small and the air bag is not expanded, the horn
button assembly and air bag ECU shall also be checked. (Refer to "Chapter 42
Supplemental Restraint System - Driver Air Bag, Replacement", "Chapter 42
Supplemental Restraint System - Airbag Control Units, Replacement")

appear on the shell, always replace it with the new parts.
• Never make the horn button assembly to be exposed in the hot air or open fire.
• A high- impedance multimeter shall be used for the system circuit fault check.

labels, always follow the precautions on the label in the process of maintenance.
• Always check the indicator light of air bag after completing the operation of the
supplemental restraint system.
