Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
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.
Take care when filling the brake and
clutch fluid reservoirs because
brake fluid can harm your hands or
eyes. If fluid gets on your hands or
in your eyes, flush the affected area
with clean water immediately. If you
still feel uncomfortable with your
hands or eyes, go to the doctor.
When racing the engine, make sure
that the gear position is in the “N”
position. In case the accelerator is
operated with the gear in any other
positions, the vehicle may move, re-
sulting in an unexpected accident.
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.
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.
Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not reuse iridium tipped spark
plugs by cleaning or regapping.

Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring

Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood or
trunk, check to see that you have
not forgotten any tools, rags, etc.
