NOTICE
A large amount of unburned gases
flowing into the three!way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
z Use only unleaded gasoline.
z Do not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three!
way catalytic converter.
z Do not turn off the ignition while
the vehicle is moving.
z Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high temperature.
z If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check!up as soon
as possible. Remember, your Toyota
dealer knows your vehicle and its
three!way catalytic converter sys-
tem best.
