WARNING
The engine compartment contains many mechanisms and fluids that may 
move suddenly, become hot, or become el ectrically 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. 
● 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 experience discomfort, consult a doctor. 
■ 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.  
■ If the fluid level is low or high 
It is normal for the brake 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 refilling,  it may indicate a serious problem.
