In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
•Air bags are designed to inflate only once. After an
air bag inflates, you’ll need some new parts for your
air bag system. If you don’t get them, the air bag
system won’t be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
•Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. Your vehicle is also equipped with a crash
sensing and diagnostic module, which records
information about the frontal air bag system. The
module records information about the readiness of
the system and when the system commands are bag
inflation. It records the status of the driver’s safety
belt usage in a crash in which the air bag deploys or
a crash in which the air bag nearly deploys. The
module also records speed, engine RPM, brake and
throttle data.
•Let only qualified technicians work on your air bag
systems. Improper service can mean that an air bag
system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air bag
covering on the driver’s and right front passenger’s
seatback, the bag may not work properly. You may
have to replace the air bag module in the steering
wheel, both the air bag module and the instrument
panel for the right front passenger’s air bag, or both
the air bag module and seatback for the driver’s and
right front passenger’s side impact air bag. Do not
open or break the air bag coverings.
