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

tric cooling fans or radiator 

grille

Be sure the power switch is off.

With the power switch in ON, the 

electric cooling fans may auto-

matically start to run if the air con-

ditioning is on and/or the coolant 

temperature is high. (
