n Engine oil consumption

l The amount of engine oil consumed depends on the oil viscosity, the quality of

the oil and the way the vehicle is driven.

l More oil is consumed under driving conditions such as high speeds and fre-

quent acceleration and deceleration.

l A new engine consumes more oil.
l 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.

l Oil consumption: Max. 1.1 qt./600 miles (1.0 L/1000 km, 0.9 lmp.qt./600

miles)

l If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles

(1000 km), contact your Lexus dealer.

n After changing the engine oil (U.S.A. only)

The engine oil maintenance data should be reset. Perform the following proce­dures:

STEP 1

Switch the display to the trip meter “A” (→P. 188) when the hybrid system
is operating.

STEP 2

STEP 3

Turn the “POWER” switch off.
While pressing the trip meter reset button (→P. 188), turn the “POWER”

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.

n Used engine oil

l Used engine oil contains potentially harmful contaminants which may cause skin

disorders such as inflammation and 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.

l Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-

pose of used oil and filters in household trash, in sewers or onto the ground. Call
your Lexus dealer, service station or auto parts store for information concerning
recycling or disposal.

l Do not leave used engine oil within the reach of children.

NOTICE

n To prevent serious engine damage

Check the oil level on a regular basis.

n When replacing the engine oil

l Be careful not to spill engine oil on the vehicle components.
l Avoid overfilling, or the engine could be damaged.
l Check the oil level on the dipstick every time you refill the vehicle.
l Be sure the engine oil filler cap is properly tightened.
