■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.
