Maintenance and care
between oil maintenance intervals.
OWhen the engine is new, for example
directly after purchasing the vehicle or
after replacing the engine
OIf low quality oil or oil of an inappropriate
viscosity is used
OWhen driving at high engine speeds or
with a heavy load, or when driving while
accelerating or decelerating frequently
OWhen leaving the engine idling for a long
time, or when driving frequently through
heavy traffic
QAfter 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 “Vehicle Settings”, and
then press “OK”.
4 Press or of the meter control
switches, select “O il Maintenance”, and
then press “OK”.
5 Select “Yes” and then press “OK”.
A message will be displayed on the multi-
information display when the reset proce-
dure has been completed.
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
QUsed engine oil
OUsed 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.
ODispose of used oil an d 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.
ODo not leave used engine oil within the
reach of children.
NOTICE
QTo prevent serious engine damage
Check the oil level on a regular basis.
QWhen replacing the engine oil
OBe careful not to spill engine oil on the
vehicle components.
OAvoid overfilling, or the engine could
be damaged.
OCheck the oil level on the dipstick
every time you refill the vehicle.
OBe sure the engine oil filler cap is prop-
erly tightened.

QOil 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.
QEngine oil selection
“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor
Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC GF-6B 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.

Vehicle specifications
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 mark 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.

Coolant type
Use either of the following:
 “Toyota Super Long Life Coolant”
 Similar high-quality ethylene glycol-
based non-silicate, non-amine, non-
nitrite, and non-borate coolant with long-
life hybrid organic acid technology
Do not use plain water alone.
