CAUTION
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.
■ When working near the cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the cooling fan may automatically start to run if
the air conditioning is on and/or the coolant temperature is high.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Maintenance and care
NOTICE
■
If 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.
■ 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 pro\
blem.

Maintenance and care
Engine oil
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 gro und. After turning off the engine,
wait more than 5 minutes for the oil to drain back into the bot-
tom of the engine.
Hold a rag under the end and pull the dipstick out.

Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check
the oil level.

■ Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as already in
the engine.

Maintenance and care
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap, turning it counterclockwise.
Add engine oil slowly.
Checking the dipstick.
Reinstall the filler cap, turning it clockwise.
The approximate quantity of oil needed to raise the level between low and
full on the dipstick is indicated as follows:
1.6 qt. (1.5 L, 1.3 lmp. qt.)
■ Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy, and good
starting in cold weather.
*: If SAE 5W-30 oil is not avail-able, SAE 10W-30 oil may be
used. However, it should be
replaced with SAE 5W-30 at
the next oil change.
■How to read oil container labels
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to
help you select the oil you should use.

■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
● A new engine consumes more oil.
● When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
● Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per
1000 km)
● If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles
(1000 km), contact your Toyota dealer.
■ After changing the engine oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures:
Turn the engine switch to the ACC or LOCK position with the odom-
eter reading shown.( P. 148)
Turn the engine switch to the ON position while holding down the
trip meter reset button.
Hold down the button until the light goes off. Before the light goes
off, it illuminates for 3 seconds, flashes for 2 seconds and illumi-
nates for 1 second.
If the system fails to reset, the light will remain flashing.

Maintenance and care
CAUTION
■
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.
● Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on regular basis.
■ When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, as 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.
