WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, when
removing a deployed airbag, rubber gloves, eye
protection, and a long-sleeved shirt should be
worn. There may be deposits on the airbag unit and
other interior surfaces. In large doses, these depos-
its may cause irritation to the skin and eyes.
WARNING: To avoid personal injury or death, use
extreme care to prevent any foreign material from
entering the side curtain airbag, or becoming
entrapped between the side curtain airbag cushion
and the roof rail garnish molding. Failure to
observe this warning could result in occupant inju-
ries upon airbag deployment.
