Tires and loading on yourTo y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 446 and 523.
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 under the
floor around the driver ’s seat for several minutes. It does
not indicate a malfunction.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
Perchlorate Material
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate.
These components may include airbag, seat belt preten-
sioners, and wireless remote control batteries.
