Maintenance and care
IS250/220d/200d_EE
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
accurately.
Oil consumption: Max. 1.0 L per 1,000 km (1.1 qt./600 miles, 0.9 Imp.
qt./600 miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every
1000 km (600 miles), contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
After changing the engine oil (IS220d and IS200d)
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer (P. 171) 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). Con-
tinue to press and hold the button until the trip meter displays
“000000”.
