●Make sure that “IGNITION ON” on the multi-information display and
the “READY” indicat or 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

●Do not leave anyt hing that may burn easily, such as paper and
rags, in the engi ne compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel or the
12-volt battery. Fu el and 12-volt battery fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and dam -
age painted surfac es. If fluid gets
on your hands or in your eyes, flush the affected area with clean water
immediately. If you still experience
discomfort, consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the power switch is off.
With the power swi tch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on
and/or the coolant temperature is
high. ( →P.504)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.
NOTICE
■If you remove th e air cleaner fil-
ter
Driving with the air cleaner filter removed may cause excessive
engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the br ake fluid level to
go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill -
ing, it may indicate a serious problem.
