enough force to cause serious iniury'
CAUTION:
. Always disconnsct lhe airbag conn€ctor(s) when the

NOTE:
. Do not install used SRS parts from another vehicle'
When repairing, use only new SRS parts'
o Carefully inspect the airbag before you install it Do
not insiall an airbag that shows signs oI being
dropped or improperly handled, such as dents' cracks
or deformation.
