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.
nWhen working on the engine compartment
lKeep hands, clothing, and tools away from the moving fan and engine
drive belt.
l 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.
l Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
l Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
l Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.

Maintenance and care
CAUTION
n
When working on the engine compartment
lTake 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, see a doctor.
n When working near the electric cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the electric cooling fan may automatically start to
run if the air conditioning is on and/or the coolant temperature is high.
n Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
nIf you remove the air cleaner
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.
n If the brake 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 pro\
blem.

244 4-3. Do-it-yourself maintenance
CAUTION
nWhen raising your vehicle
Make sure to observe the following to reduce the possibility of death or\
seri-
ous injury.
lDo not use the jack that was supplied with your vehicle.
l Do not put any part of your body or get underneath the vehicle supported
only by the floor jack.
Always use automotive jack stands on a solid, level surface.
l Do not start the engine while the vehicle is supported by the floor jack.
l Stop the vehicle on level firm ground, firmly set the parking brake and put
the shift lever in P (automatic transmission) or R (manual transmission).
l Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
l Do not raise the vehicle while someone is in the vehicle.
l When raising the vehicle, do not place any objects on top of or underneath
the floor jack.
