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.
■ When working near the electric c ooling fans or radiator grille
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 temperature is high. ( →P. 263)
■ 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.

254 4-3. Do-it-yourself maintenance
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.

256 4-3. Do-it-yourself maintenance
WARNING
■When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
●When using a floor jack, follow the instructions of the manual provided with
the jack.
● Do not use the jack that was supplied with your vehicle.
● Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
● Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
● Do not start the engine while the vehicle is supported by the floor jack.
● Stop the vehicle on level, firm ground, firmly set the parking brake and shift
the shift lever to P (vehicles with an automatic transmission) or R (vehicles
with a manual transmission).
● 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.
● Do not raise the vehicle while someone is in the vehicle.
● When raising the vehicle, do not place any object on top of or underneath
the floor jack.
● When raising the vehicle, ensure that there is sufficient surrounding space.
The vehicle’s position may change slightly when lowered.
●Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine
● If low quality oil or oil of an inappropriate viscosity is used
● When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
WARNING
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
● Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call your Toyota dealer, service station or auto parts store for information
concerning recycling or disposal.
