Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground . After turning off the hybrid
system, wait more than five mi nutes for the oil to drain back
into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.

■Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil. Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Install the filler cap, turning it clockwise.
The approximate quantity of oil needed to raise the level from low to full on
the dipstick is indicated as follows:
1.6 qt. (1.5 L, 1.3 lmp. qt.)
■ Recommended viscosity
SAE 5W-20 or 0W-20
SAE 5W-20 or 0W-20 engine oil
may be used. However, SAE 0W-
20 is the best choice for good fuel
economy, and good starting in
cold weather.

How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.
OIL identification mark
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) Certifica-
tion Mark is displayed on the
front of the container.
■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
● A new engine consumes more oil.
● When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
● Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per
1000 km)
● If your vehicle consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600
miles (1000 km), contact your Toyota dealer.
■ Changing the engine oil (U.S.A. only)
To reset the oil change system, follow the procedure below:
Set the “POWER” switch OFF with the trip meter A reading shown.
(→P. 189)
While pressing the trip meter reset button, set the “POWER” switch
in ON mode.
Continue to press and hold the button until “COMPLETE” appears
on the multi-information display.

CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
● Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call your Toyota dealer, service station or auto parts store for
information concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you refill the vehicle.
● Be sure the engine oil filler cap is properly tightened.

Maintenance and care
Coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the hybrid system is cold.
Engine coolant reservoir Reservoir cap
“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.

“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, coolant reservoir cap, drain cock and
water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
■ Coolant selection
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.
U.S.A.: Toyota Super Long Life Coolant is a mixture of 50% coolant and 50% deionized water. (Enabled: -31 °F [-35 °C])
Canada: Toyota Super Long Life Coolant is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 °F [-42 °C])
For more details about coolant, contact your Toyota dealer.
