■Adding engine oil
If the oil level is below or near the low
level mark, add engine oil of the same
type as that already in the engine.
1 Remove the oil filler cap by turning
it counterclockwise.
2 Add engine oil slowly, checking the
dipstick.
3 Install the oil filler cap by turning it
clockwise.
■Engine oil consumption
A certain amount of engine oil will be con-
sumed while driving. In the following situa-
tions, oil consumption may increase, and
engine oil may need to be refilled in
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, when towing, or when
driving while accelerating or decelerat-

ing 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
Press or of the meter control
switches and select .
2
Press or of the meter control
switches, select “Vehicle Settings” and
then press “OK”.
3
Press or of the meter control
switches, select “Oil Maintenance” and
then press and hold the “OK”.
4
Select “Yes” and press “OK”.
“Reset Complete” will be displayed when
the reset procedure has been completed.
The coolant level is satisfactory if it is
between the “FULL” and “LOW” lines
on the reservoir when the engine is
cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW” line,
add coolant up to the “FULL” line.
( P.386)
■Coolant selection
Only use “Toyota Super Long Life Coolant”
or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
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, ser-
vice 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.

■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.
