Oil identification mark
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is added to some oil con-
tainers to help you select the oil you
should use.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”.
CAUTION
The coolant heat storage tank reaches
high temperature inside. It is danger-
ous if hot coolant is discharged when
replacing. For replacement of the
coolant, contact your Toyota dealer.
Look at the seethrough coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the “FULL” and “LOW” lines
on the reservoir. If the level is low, add
the coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with hybrid system temperature. However,
if the level is on or below the “LOW” line,
add coolant. Bring the level up to the
“FULL” 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.
Checking the coolant level

403
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 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 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 coolant sys-
tem with proper usage. “Toyota Super
Long Life Coolant” is formulated with
long −life hybrid organic acid technology
and has been specifically designed to
avoid cooling system malfunction on
Toyota vehicles.
Please contact your Toyota dealer for fur-
ther details.

404
If either of the above parts is 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.
Checking brake fluid
82p002b
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 or
when the fluid level in the accumulator is
high.If the level is low, take your vehicle to
a Toyota dealer as soon as possible. Do
not drive if the red brake system warn-
ing light is on. Call a Toyota dealer for
assistance.
If the fluid level goes down soon after your
vehicle is serviced, it may indicate a seri-
ous mechanical problem.
CAUTION
Brake fluid can harm your hands or
eyes. If fluid gets on your hands or
in your eyes, flush the affected area
with clean water immediately. 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.
