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
●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 or 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, see a doctor.

WARNING
■
When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system: Be sure the engine switch is
off. With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( →P. 334)
Vehicles with a smart entry & start system: Be sure the “ENGINE START
STOP” switch is off. With the “ENG INE START STOP” switch in IGNITION
ON mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the cool ant temperature is high. (→P. 334)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the 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.

WARNING
■
Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
NOTICE
■When opening the hood
●Do not lift up or operate the wipers. Doing so may cause the hood and wip-
ers to contact, scratching the hood.
● Use caution when opening the engine hood in windy weather as it may
close suddenly in strong wind.
● Do not attach any accessories other than genuine Toyota products to the
engine hood. Such additional weight on the engine hood may cause it to
be too heavy to be supported by the supporting rod when opened.
■ When closing the hood
Do not apply excessive weight or force when closing the hood as doing so
may result in damage.
