• Do not use the airbag system and pretensioners
on other vehicles. When replacing parts, be sure to
replace them with new parts.
• When checking the airbag system, be sure to
use a digital circuit tester. Use of an analog circuit
tester may cause the airbag to activate erroneously
due to a minimal current inside tester.
