Maintenance and care
between oil maintenance intervals.
●When the engine is new, for example
directly after purchasing the vehicle or
after replacing the engine
●If low quality oil or oil of an inappropriate
viscosity is used
●When driving at high engine speeds or
with a heavy load, or when driving while
accelerating or decelerating frequently
●When leaving the engine idling for a long
time, or when driving frequently through
heavy traffic
■After changing the engine oil
The engine oil maintenance data should be
reset. Perform the following procedures:
1
While the vehicle is stopped, press
of the meter control switches.
2
Press or of the meter control
switches, and select .
3
Press or of the meter control
switches, select “Veh icle Settings”, and
then press “OK”.
4
Press or of the meter control
switches, select “Oil Maintenance”, and
then press “OK”.
5
Select “Yes” and then press “OK”.
A message will be displayed on the multi-
information display.
The coolant level is satisfactory if it is
between the “F”/“FULL” and
“L”/“LOW” lines on the reservoir when
the hybrid system is cold.

WARNING
■Used engine oil
●Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as inflamma-
tion and skin cancer, so care should be
taken to avoid prolonged and
repeated contact. To remove used
engine oil from your skin, wash thor-
oughly with soap and water.
●Dispose of used oil and filters only in a
safe and acceptable manner. Do not
dispose of used oil and filters in house-
hold trash, in sewers or onto the
ground.
Call your Lexus dealer, service station
or auto parts store for information
concerning recycling or disposal.
●Do not leave used engine oil within the
reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the
vehicle components.
●Avoid overfilling, or the engine could
be damaged.
●Check the oil level on the dipstick
every time you refill the vehicle.
●Be sure the engine o il filler cap is prop-
erly tightened.

■Oil capacity (Drain and refill [Ref-
erence
*])
*: The engine oil capacity is a reference quantity to be used when changing the
engine oil. Warm up the engine and turn
off the hybrid system, wait more than 5
minutes, and check the oil level on the
dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil”
or equivalent to satisfy the following
grade and viscosity.
Oil grade: API SN/RC multigrade
engine oil
Recommended viscosity: SAE 0W-16 SAE 0W-16 is the best choice for good
fuel economy and good
starting in cold
weather.
If SAE 0W-16 is not available, SAE
0W-20 oil may be used. However, it
must be replaced with SAE 0W-16 at
the next oil change.
Outside temperature
Oil viscosity (0W-16 is explained here
as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which allows

cold startability. Oils with a lower
value before the W allow for easier
starting of the engine in cold
weather.
• The 16 in 0W-16 indicates the vis- cosity characteristic of the oil when
the oil is at high temperature. An oil
with a higher viscosity (one with a
higher value) may be better suited if
the vehicle is operated at high
speeds, or under extreme load con-
ditions. How to read oil container label:
API registered marks is added to some
oil containers to help you select the oil
you should use.
*: The fluid capacity is a reference quantity.
If replacement is necessary, contact your Lexus dealer.
