The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SL. The
center portion of the label shows the SAE viscosity grade
such as SAE 5W±30. ªEnergy±Conservingº, shown in the

CHECKING THE ENGINE COOLANTLEVEL
SV62006

1Reservoir cap 2Upper line 3Lower line
Look at the see±through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between theªFULLº and ªLº lines on the reservoir. If the
level is low, add the coolant. (For the coolant type, see
ªCoolant type selectionº described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the ªLº line,
add coolant. Bring the level up to the ªFULLº 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, engine coolant filler cap, radiator cap and drain cock
and water pump. If you can find no leak, have your Lexus 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 engine is hot.
Coolant type selection
Use of improper coolants may damage your engine cooling
system.
Only use ªToyota Super Long Life Coolantº 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.ЪToyota Super Long Life Coolantº is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about ±35 C (±31F).
For the CanadaЪToyota Super Long Life Coolantº is a
mixture of 55% coolant and 45% deionized water. This coolant
provides protection down to about ±42 C (±44F).
NOTICE
Do not use plain water alone.

338Lexus recommends ªToyota Super Long Life Coolantº, which
has been tested to ensure that it will not cause corrosion nor
result in malfunction of your engine coolant system with proper
usage. ªToyota Super Long Life Coolantº is formulated with
long±life hybrid organic acid technology and has been
specifically designed to avoid engine cooling system
malfunction on Lexus vehicles.
Please contact your Lexus dealer for further details.
CHECKING THE RADIATOR AND
CONDENSER
If either of the above parts are extremely dirty or you are not
sure of their condition, take you vehicle to a Lexus dealer.
CAUTION
To prevent burning yourself, be careful not to touch the
radiator or condenser when the engine is hot.
NOTICE
To prevent damage to the radiator and condenser, do
not perform the work by yourself.
