7-3. Do-it-yourself maintenance
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:
●Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, 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 or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Be sure the engine switch is in the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system). With the engine
switch in the “ON” position (vehicles without a smart key system) or IGNI-
TION ON mode (vehicles with a smart key system), the electric cooling fans
may automatically start to run if the air conditioning is on and/or the coolant
temperature is high. ( P. 491)
■ 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.
