■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 co nditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, 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 lmp.qt./600 miles (1.0 L per 1000
km). If the vehicle consumes more than this amount, contact your Lexus dealer.

nect the ground cable.
●Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the battery.

dure.)

close any door, then attempt to start the hybrid system.
If the system will not start even after mult iple attempts at both methods, contact
