If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this part.
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 Part 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 ºParts and
toolsº.
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:

Do not drive with the air cleaner
filter removed, or excessive enginewear could result. Also backfiring could cause a fire in the engine
compartment.
Be careful not to scratch the glasssurface 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 on performing do- it- yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.

Parts (if level is low):
Engine oil API grade SJ,
ºEnergy- Conservingº or ILSAC
multigrade having viscosity proper for
your climate
Tools: Rag or paper towel

Checking the engine coolant level
Parts (if level is low): ºToyota Long Life Coolantº or equiva-
lent
See Chapter 7- 2 for details about cool-
ant type selection.
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)
Checking power steering fluid

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.

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 (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure allaccessories are turned off.

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 ºFuse locationsº 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 using
the pull- out tool. The location of the pull-
out tool is shown in the illustration.
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 ºPWR
OUTLETº or ºA.Cº 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.
