Parts and tools
Here is a list of parts and tools you will
need on performing 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):
Engine oil API grade SH, ”Energy-Con-
serving II” or SJ, “Energy −Conserving”
multigrade or ILSAC multigrade having
viscosity proper for your climate
Tools: Rag or paper towel
Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low): Ethylene-glycol antifreeze
Demineralized or distilled 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)

II or III
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)

CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas. Do not cause a spark from the bat-
tery with tools.
Do not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid. Avoid contact with eyes, skin or
clothes.
Never ingest electrolyte.
Wear protective safety glasses when
working near the battery.
Keep children away from the bat-
tery.
EMERGENCY MEASURES If electrolyte gets in your eyes,
flush your eyes with clean water
immediately and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi-
cal office.
If electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
If electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immediate-
ly take off the exposed clothing and
follow the procedure above, if nec-
essary.
If you happen to swallow electro-
lyte, drink a large quantity of water
or milk. Follow with milk of magne-
sia, beaten raw egg or vegetable
oil. Then go immediately for emer-
gency help.

—Precautions

T100(U)191
Battery recharging precautions
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
Checking and replacing fuses

T100(U)
192
If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See ”Fuse locations” in Chapter 7 −1 for
locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull a suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
Part 8 of this manual for the functions
controlled by each circuit.
Type A fuses can be pulled out by the
pull-out tool. If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the ”CIG.”,
”RADIO”, ”DOME” or ”A/C” fuse, which
may be dispensable for normal driving,
and use it if its amperage rating is the
same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
as possible to, the rating. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies.
If the new fuse immediately blows out,
there is a problem with the electrical sys-
tem. Have your Toyota dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.
