1. When removing the horn button assembly or handling a new horn button, it should be placed with the pad top surface facing upward. Placing it
with the pad surface facing downward may lead to a serious accident if the airbag accidentally inflates. Also, do not place the horn button on
top of one another.
2. Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous.).
3. Grease should not be applied to the horn button assembly and the pad should not be cleaned with detergents of any kinds.
4. Store the horn button assembly where the ambient temperature remains below 93 °C (200 °F), without high humidity and away from electrical
noise.
5. When using electric welding, first disconnect the airbag connector (2 yellow pins) under the steering column near the combination switch
connector before starting work.
6. When disposing of the vehicle or the horn button assembly alone, the airbag should be deployed using an SST before disposal.
Perform the operation in a safe place away from electrical noise.
d. INSTRUMENT PANEL PASSENGER AIRBAG ASSEMBLY
1. Always store a removed or new instrument panel passenger airbag assembly with the airbag inflation direction facing upward. Placing the
airbag assembly with the airbag inflation direction facing downward could cause a serious accident if the airbag inflates.
