■“Oil Level” (engine oil level)
The amount of oil remaining in the ta nk can be calculated and is shown
on a scale of one to ten . If the engine oil level cannot be measured, the
reason will be shown on the screen.
Conditions for measurement
● The engine oil temperature is between 203 F and 230F (95C and
110 C).
● The engine is idling.
● The vehicle is stopped on level ground.
Select “Oil Level” and press right
on the control pad.
The amount of engine oil remain-
ing is measured automatically.
The amount of time needed to
complete the measurement is
counted down on the screen.

Measurement resultOnce measurement is complete,
the result will be displayed.
The oil amount between the maxi-
mum and minimum markings is
approximately 2.1 qt. (2.0 L, 1.8
Imp. qt.).
As the engine oil level in the oil
tank varies depending on the driv-
ing condition of the vehicle imme-
diately before measurement, the
results may vary even if the overall
oil amount is constant.
Perform the following actions as necessary according to the measure-
ment results:
● If the oil level is low, add engine oil as needed. ( P. 257)
Even if the measurement result shows th at the engine oil is below the maxi-
mum level, be careful not to add more oil than necessary. If unsure of how
much oil to add, contact your Lexus dealer.
● If “Engine oil level low Check oil le vel” is displayed on the meter, avoid
high load driving and add oil immediately.
Do not let the oil level reach or fall below the minimum marking, as doing so
may cause engine damage.

tions have been met, have the vehicle inspected by your Lexus dealer.
