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 by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the filler cap, turning it clockwise.

■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 Imp. qt./600 miles (1.0 L per
1000 km)
● If you consume more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Toyota dealer.
■ After changing the engine oil (U.S.A. only)
To reset the oil change system, follow the procedure below:
Turn off the hybrid system with the trip meter A reading shown.
(P. 150)
The “POWER” switch must be set in ON mode while holding down
the trip meter reset knob. A message “OIL MILEAGE RESET
MODE” will appear on the display.
Hold down the knob for at least 5 seconds. A message “COM-
PLETE” will appear and the message “OIL MILEAGE RESET
MODE” goes off.

Maintenance and care
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, as 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.

■ Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC multigrade engine oil
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.
The 0W portion of the oil viscosity rating indicates the characteristic of the
oil which allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.

The 20 in 0W-20 indicates the oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity may be better suited if the vehi-
cle is operated at high speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.
