Maintenance and care
CAUTION
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  indicator  on  the  “POWER”  switch  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  auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( oP.   4 7 1 )
■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.
