STARTING AND DRIVING
405
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:
Use only unleaded gasoline.
Do not drive with an extremely low fuel level; running
out of fuel could cause the engine to misfire, creating
an excessive load on the three−way catalytic
converter.
Do not turn off the ignition while the vehicle is
moving.
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 extremely high
temperature.
If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check−up as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its three−way catalytic
converter system best.
To ensure that the three−way catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
“Owner’s Manual Supplement / Scheduled
Maintenance”.
Do not apply a coating agent such as an anti−rust
under−coating to the exhaust pipe.
