Maintenance and care
IS350/250_U
■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/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 oil change system should be reset. Perform the following procedures: Switch the display to the odometer ( →P. 151) when the engine is running.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to IGNITION ON mode (but do not start the engine
because otherwise the reset mode will be cancelled). Continue to press
and hold the button until the trip meter displays “000000”.
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 dis-
pose of used oil and filters in househol d trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
