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 "POWER ON" on the meter 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 or the battery. Fuel and battery fumes are flammable.

When working near the electric cooling fan or radiator grille

Be sure the power switch is OFF.

With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is high

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.
