■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure
performance of each system. If non-Toyota parts are used in replacement or if
a repair shop other than a Toyota dealer performs repairs, confirm the war-

●Toyota technicians are well-trained specialists and are kept up to date with
the latest service information. They are well informed about the operation of
all systems on your vehicle.

been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, y our Toyota dealer will promptly take
care of it.

● Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of Califor-
nia to cause cancer and birth defects or other reproductive harm. Avoid

WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working on the engine compartment
●Make sure that the “POWER ON” on the multi-information display or the
smart key system indicator, and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioni ng is on and/or the coolant temperature
is high. ( P. 421)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■ If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
