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.
Q When working on the engine compartment
O Make sure that the “Accessory”, “Ignition ON” or mileage display (P. 2 1 3 )
on the main display and the “READY” indicator are both off.
O Keep hands, clothing and tools away from the moving fan.
O 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.
O Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
O Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
O Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
O Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately. If you still experi ence discom-
fort, consult a doctor.
Q 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 conditioning is on and/or the coo lant temperature
is high. ( P. 593)
