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 section 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 203.
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 and trunk room—the
engine, radiator, exhaust manifold,
power steering fluid reservoir and
spark plug boots, etc.—will be hot.
So be careful not to touch them.
Oil, fluids and spark plugs may also
be hot.
If the engine is hot, do not remove
the coolant reservoir cap or air re-
lease valve 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.

precautions

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 or
trunk, check to see that you have
not forgotten 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 page 208 in Section 7−2 for de-
tails about engine oil selection.
Tools:
Rag or paper towel
Funnel (only for adding oil)
CHECKING THE ENGINE COOLANT
LEVEL
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.
Tools:
Funnel (only for adding coolant)CHECKING BRAKE FLUID
Parts (if level is low):
SAE J1703 or FMVSS No.116 DOT 3
brake fluid
Tools:
Rag or paper towel
Funnel (only for adding fluid)
CHECKING POWER STEERING FLUID
Parts (if level is low):
Toyota P.S fluid EH or equivalent
Tools:
Rag or paper towel
Funnel (only for adding fluid)
CHECKING BATTERY CONDITION
Tools:
Warm water
Baking soda
Grease
Conventional wrench (for terminal
clamp bolts)
CHECKING AND REPLACING FUSES
Parts (if replacement is necessary):
Genuine Toyota fuse or equivalent with
same amperage rating as original

2122005 MR2 from Aug. ’04Prod. (OM17527U)
If the level is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir.
Remove and replace the reservoir cap by
hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cap back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess moisture can cause a
dangerous loss of braking.
CAUTION
Take care when filling the reservoir
because brake fluid can harm your
hands or eyes. If fluid gets on your
hands or in your eyes, flush the af-
fected area with clean water immedi-
ately. If you still feel uncomfortable
with your hands or eyes, go to the
doctor.
NOTICE
If you spill some of the fluid, be sure
to wipe it off to prevent it from dam-
aging the parts or paintwork.

Check the fluid level through the reser-
voir. If necessary, add Toyota P.S fluid
EH or equivalent.
Before checking the power steering
fluid, remove the cover inside the
trunk. (See “Replacing light bulbs” on
page 228 in Section 73.)
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60C—80C or 140F—175F). You
may also check the level when the fluid
is cold (about room temperature,
10C—30C or 50F—85F) if the engine
has not been run for about five hours.
