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 seethrough 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 the Canada—“Toyota 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.

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.
To check the fluid level, simply look at
the seethrough 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. So
be sure to keep the reservoir filled.
If the reservoir needs frequent refi
lling, it
may indicate a serious mechanical prob-
lem.
