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.

Maintenance and care
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.
Remove the sand and dust from around the dipstick.
Holding a rag under the end,
pull the dipstick out.
Wipe the dipstick clean.
Make sure that the inlet of the oil level gauge guide and O-ring of the
dipstick are free from sand and dust.
If the O-ring is damaged, replace it with a new one.
Reinsert the dipstick fully.
Holding a rag under the end,
pull the dipstick out and
check the oil level.
Low
Normal
Excessive
The shape of the dipstick may
differ depending on the type
of vehicle or engine.
Wipe the dipstick and reinsert it fully.

■Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as that
already in the engine.
Make sure to check the oil type and prepare the items needed
before adding oil.
Remove the sand and dust from around the oil filler cap.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
■ Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following
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, when towing
(models for model code destination W*), or when driving while accelerating
or decelerating frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
*: See “Checking your vehicle’s model” if you are not sure of which model
your vehicle is. ( P. 11 )

Maintenance and care
■After changing the engine oil (models for model code destination W*)
The engine oil maintenance data should be reset. Perform the following pro-
cedures:
Switch the display to the trip meter A ( P. 134) when the engine switch is
in the “ON” position (vehicles without smart entry & start system) or IGNI-
TION ON mode (vehicles with smart entry & start system).
Turn the engine switch to the “LOCK” position (vehicles without smart entry
& start system) or off (vehicles with smart entry & start system).
While pressing the odometer/trip meter display change button ( P. 134),
turn the engine switch to the “ON” position (vehicles without smart entry &
start system) or IGNITION ON mode (vehicles with smart entry & start sys-
tem). (Do not start the engine because reset mode will be canceled.) Con-
tinue to press and hold the button for more than one second after the trip
meter displays “000000”.
*: See “Checking your vehicle’s model” if you are not sure of which model
your vehicle is. ( P. 1 1 )
WARNING
■Used engine oil
● Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation and 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 any authorized Toyota reta iler or Toyota authorized repairer,
or any reliable repairer, service station or auto parts store for information
concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
● Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you refill the vehicle.
● Be sure the engine oil filler cap is properly tightened.
