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 overfill automatic transmis-
sion fluid, or the transmission
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.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.

To ensure excellent lubrication perfor-
mance for your engine, Toyota Genuine
Motor Oil" is available, which has been
specifically tested and approved for all
Toyota engines.
Please contact your Toyota dealer for fur-
ther details about Toyota Genuine Motor
Oil".Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the F" and L" lines on the reservoir.
If the level is low, add the coolant. (For
the coolant type, see Coolant type
selection" described below.)
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the L" line, add
coolant. Bring the level up to the F" line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system.
Only use Toyota Super Long Life Coolant"
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life
hybrid organic acid technology. (Coolant
with long−life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
For the U.S.A.Toyota Super Long Life
Coolant" is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35
C
(−31 F).
For CanadaToyota Super Long Life
Coolant" is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
(−44 F).
NOTICE
Do not use plain water alone.
Checking the engine coolant
level

439
Toyota recommends Toyota Super Long
Life Coolant", which has been tested to
ensure that it will not cause corrosion nor
result in malfunction of your engine
coolant system with proper usage. Toyota
Super Long Life Coolant" is formulated
with long−life hybrid organic acid
technology and has been specifically
designed to avoid engine cooling system
malfunction on Toyota vehicles.
Please contact your Toyota dealer for
further details.If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to a Toyota dealer.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator or con-
denser when the engine is hot.
NOTICE
To prevent damage to the radiator
and condenser, do not perform the
work by yourself.
CY72025
To check the fluid level, simply look at
the see−through reservoir. The level
should be between the MAX" and
MIN" lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear or
when the fluid level in the accumulator is
high.
If the reservoir needs frequent ref
illing, it
may indicate a serious mechanical prob-
lem.
If the level is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir.
