Checking the engine coolant  
level  
Oil identification marks  
Look at the see−through coolant reser-  
voir when the engine is cold. The cool-  
ant level is satisfactory if it is between  
the “FULL” and “LOW” lines on the  
reservoir. If the level is low, add ethyl-

ene−glycol type coolant for  
a
proper  
corrosion protection of aluminum com-  
ponents.  
The top portion of the label shows the oil  
quality by API (American Petroleum Insti-  
tute) designations such as SL. The center  
portion of the label shows the SAE viscos-  
ity grade such as SAE 5W−30. “Energy−  
Conserving” shown in the lower portion,  
indicates that the oil has fuel−saving ca-  
pabilities.  
The coolant level in the reservoir will vary  
with engine temperature. However, if the  
level is on or below the “LOW” line, add  
coolant. Bring the level up to the “FULL”  
line.  
Always use ethylene−glycol type coolant  
for a proper corrosion protection of alumi-  
num components. See information in the  
next column.  
To ensure the best possible lubrication  
performance for your engine, the “Toyota  
Genuine Motor Oil” range is available,  
which has been specifically tested and ap-  
proved for all Toyota engines.  
The ILSAC (International Lubricant Stan-  
dardization and Approval Committee) Certi-  
fication Mark is displayed on the front of  
the container.  
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.  
Please contact your Toyota dealer for fur-  
ther details of the “Toyota Genuine Motor  
Oil” range.  
If you can find no leak, have your Toyota  
dealer test the cap pressure and check  
for leaks in the cooling system.

CAUTION  
on freeze protection. Follow the manufac-  
turer’s directions for how much to mix  
with plain water (preferably demineralized  
water or distilled water). The total capacity  
of the cooling system is given in Section  
8.  
To prevent burning yourself, do not  
remove the radiator cap when the en-  
gine is hot.  
Coolant type selection  
We recommend to use 50% solution for  
your Toyota, to provide protection down to  
about −35_C (−31_F). When it is extreme-  
ly cold, to provide protection down to  
about −50_C (−58_F), 60% solution is rec-  
ommended. Do not use more than 70%  
solution for better coolant performance.  
Use of improper coolants may damage  
your engine cooling system. Your coolant  
must contain ethylene−glycol type coolant  
for a proper corrosion protection of your  
engine that

The engine cooling system is integral to  
maximizing performance of your Toyota  
vehicle. In line with this, it is strongly  
recommended that you use “Toyota  
Genuine Long Life Coolant” for protecting  
the system, as it is an ethylene−glycol  
based premium antifreeze coolant with  
excellent corrosion protection properties  
that has been specifically formulated for  
use in Toyota vehicles.  
We have used “Toyota Genuine Long Life  
Coolant” in your Toyota vehicle. In order  
to avoid technical problems, we strongly  
recommend using “Toyota Genuine Long  
Life Coolant” or equivalent.  
NOTICE  
Do not use alcohol type antifreeze or  
plain water alone.  
In addition to preventing freezing and  
subsequent damage to the engine, this  
type of coolant will also prevent corrosion.  
Further supplemental inhibitors or additives  
are neither needed nor recommended.  
Please contact your Toyota dealer for fur-  
ther details of the “Toyota Genuine Long  
Life Coolant” range.
