■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 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 accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 Imp. qt./600 miles (1.0 L per 1000
km)
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
■After changing the engine oil (U.S.A. only)
The engine oil maintenance data should be reset. Perform the following proce-
dures:Switch the display to the trip meter “A” when the hybrid system is operat-
ing. (→P. 1 6 3 )
Turn the “POWER” switch off.
While pressing the trip meter reset button ( →P. 1 6 3 ) , t u r n t h e “ P O W E R ”
switch to ON mode (do not start the hybrid system because otherwise
the reset mode will be canceled). Continue to press and hold the button
until the trip meter displays “000000” and the multi-information display
indicates that the reset is complete.
