the underside or rear of the vehicle is damaged , have a competent
mech anic inspect the complete exhaust system and adj acen t body
areas fo r bro ke n , damaged , de terio rated, or mispositioned parts.
Open seams or loose connections could permit exha ust fum es to
seep in to the trunk or passenger compartment. In addition , in-
spect the exhaust system each time the vehicle is raised for lub ri-
cation or oil change. Replace as required .
