If your vehicle overheats
●The high engine coolant temperature warning light ( →P. 422)
comes on or flashes, or a loss of engine power is experienced. (For
example, the vehicle sp eed does not increase.)
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled

Vehicle specifications
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If this
happens, contact your Toyota dealer for service.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.

WARNING
■
During customization
As the engine needs to be running during customization, ensure that the
vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may
collect and enter the vehicle. This may lead to death or a serious health
hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.
