SECTION 2

215
For detailed information on oil level check,
see “Checking the engine oil level” on
page 296.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drivabil-
ity.
Brake system
BRAKE SYSTEM
This brake system has two independent
hydraulic circuits. If either circuit should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power−assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sound continuously.
In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er.

If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do−it−yourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Section 6,
there are still a number of items that must
be done by a qualified technician with
special tools.
For information on tools and parts for do −
it −yourself maintenance, see “Parts and
tools” on page 293.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve: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
compartment—the 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.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fan or radiator grille. With the igni-
tion on, the electric cooling fan will
automatically start to run if 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.
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.
Doityourself service
precautions

293
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.
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 nonsilicate,
nonamine, nonnitrite and nonbo-
rate coolant with longlife 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 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 iridiumtipped spark
plugs by cleaning or regapping.
 Do not overfill automatic transmis-
sion fluid, transfer oil and power
steering fluid, or the transmission,
transfer and power steering could
be damaged.
 Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
 Be careful not to scratch the glass
surface with the wiper frame.
 When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.
Parts and tools
Here is a list of parts and tools you will
need to perform do −it−yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
CHECKING THE ENGINE OIL LEVEL
Parts (if level is low):
“Toyota Genuine Motor Oil” or equiva-
lent. See “Checking the engine oil lev-
el” on page 296 for instructions.
Tools:
Rag or paper towel
Funnel (only for adding oil)
CHECKING THE ENGINE COOLANT LEV-
EL
Parts (if level is low):
“Toyota Super Long Life Coolant” or
similar high quality ethylene glycol
based non −silicate, non −amine, non− ni-
trite, and non −borate coolant with long −
life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deion-
ized water.
