■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, fre-
quent 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 the vehicle consumes 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)
The oil change system should be rese t. Perform the following steps:
Turn the “POWER” switch OFF with the trip meter A shown.
Turn the “POWER” switch ON with the MPH or km/h button 
( P. 183) held down.
Keep pressing the button until the odometer indicates “000000” and
the multi-information display indicates that the reset is complete.

PRIUS_U (OM47668U) U.S.A.
Lubrication system■ Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat-
isfy the following grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 may be used. How-
ever, it must be replaced with
SAE 0W-20 at the next oil
change.
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.
