CAUTION
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartmentthe engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
 Add only Toyota Super Long Life
Coolant" or similar high quality eth-
ylene glycol based non−silicate,
non−amine, non−nitrite, and non−bo-
rate coolant with long−life hybrid
organic acid technology to fill the
radiator. Toyota Super Long Life
Coolant" is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).
 If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
 Do not allow dirt or anything else
to fall through the spark plug holes.
 Do not pry the outer electrode of a
spark plug against the center elec-
trode.

ENGINE OIL SELECTION
Toyota Genuine Motor Oil" is used in
your Toyota vehicle. Use Toyota approved
Toyota Genuine Motor Oil" or equivalent
to satisfy the following grade and
viscosity.
Oil grade:ILSAC multigrade engine oil
Recommended viscosity: SAE 5W−30
OIL008
Outside temperature
SAE 5W−30 is the best choice for good
fuel economy, and good starting in cold
weather. If SAE 5W−30 oil is not available, SAE
10W−30 oil may be used. However, it
should be replaced with SAE 5W−30 at
the next oil change.
Oil identification mark
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is added to some oil con-
tainers to help you select the oil you
should use.

443
Incorrect tire inflation pressure may
waste fuel, reduce the comfort of driv-
ing, reduce tire life and make your ve-
hicle less safe to drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure (underinfla-
tion)

Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an
overheated tire
 Poor sealing of the tire bead
Wheel deformation and/or tire
separation
 A greater possibility of tire
damage from road hazards
High tire pressure (overinfla-
tion)
 Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire
damage from road hazards
CY72126
Treadwear indicator
CHECKING YOUR TIRES
Check the tire’s tread for treadwear
indicators. If the indicators show,
replace the tires. The location of
treadwear indicators is shown by
the TWI" or 
Δ" marks, etc.,
molded on the sidewall of each
tire.
