Scrapping of your Scion
The SRS airbag and seat belt pretensioner devices in
your Scion contain explosive chemicals. If the vehicle is
scrapped with the airbags and seat belt pretensioners
left as they are, this may cause an accident such as a
fire. Be sure to have the systems of the SRS airbag
and seat belt pretensioner removed and disposed of by
a qualified service shop or by your Scion dealer before
you scrap your vehicle.
Leak detection pump
This pump performs fuel evaporation leakage check.
This check is done approximately five hours after the
engine is turned off. So you may hear sound coming
from underneath the luggage compartment for several
minutes. It does not indicate a malfunction.
