WARNING
The engine compartment contains many
mechanisms and fluids that may move
suddenly, become hot, or become elec-
trically energized. To avoid death or seri-
ous injury, observe the following
precautions.
■When working on the engine com-
partment
●LC500h: Make sure that the “IGNI-
TION ON” on the multi-information
display and the “READY” indicator are
both off.
●Keep hands, clothi ng and tools away
from the moving fan and engine drive
belt.
ItemsParts and tools●LC500: Be careful not to touch the
engine, radiator, exhaust manifold, etc.
right after driving as they may be hot.
Oil and other fluids may also be hot.
LC500h: Be careful not to touch the
engine, power control unit, radiator,
exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may burn
easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.
■When working near the electric cool-
ing fan or radiator grille
Be sure the engine switch
With the engine switch
IGNITION ON mode
electric cooling fan may automatically
start to run if the air conditioning is on
and/or the coolant temperature is high.
( P.301)
■Safety glasses
Wear safety glasses to prevent flying or
falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine
wear due to dirt in the air.

Maintenance and care
LC500
LC500h
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, 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 (LC500h)
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.
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.
3527-2. Steps to take in an emergency
• “Access System with Elec. Key Malfunction”
• “Shift system malfunction”
• “P switch malfunction”
• “Shift system unavailable”
●If any of the following messages is shown on the multi-information di splay, it may indicate
a malfunction in a system or part. Immediatel y have the vehicle inspected by your Lexus
dealer.
• “Hybrid System Malfunction” (LC500h)
•“Check Engine”
•“Hybrid Battery System Malfunction” (LC500h)
• “Accelerator System Malfunction”
• “Hybrid system stopped” (LC500h)
• “Engine stopped”(LC500h)
●If any of the following messages is shown on the multi-information di splay, it may indicate
a malfunction. Immediately stop the vehicle and contact your Lexus dealer.
• “Braking Power Low”
• “Charging System Malfunction”
• “Oil Pressure Low”
●If “Aux Battery Low” is shown, observe the following. (LC500h)
• If the message disappears in a few minutes*
Keep the hybrid system operating for more than approximately 15 minutes to charge the
12-volt battery.
• If the message does not disappear Refer to “If the 12-volt battery is discharged” ( P.361) to start the hybrid system
*: It is displayed for approximately 6 seconds.
●If “Battery low” is shown, the 12-volt battery charge is insufficient. Recharge or replace the
12-volt battery.
●If “Maintenance Required for Traction battery Cooling Parts” is shown, the filters may be
clogged, the air intake vents may be blocked, or there may be a gap in the duct. There-
fore, perform the following correction procedure. (LC500h)
• If the air intake vents and filters of the hybrid battery (traction battery) are dirty, perform the procedure on P.283 to clean them.
• If the warning message is shown when the air intake vents and filters of the hybrid battery
(traction battery) are not dirty, have th e vehicle inspected by your Lexus dealer.
■If a message that indicates the need fo r visiting your Lexus dealer is shown
The system or part shown on the multi-information display is malfunctioning. Have the vehi-
cle inspected by your Lexus dealer immediately.
■Warning buzzer
In some cases, the buzzer may not be heard du e to being in a noisy location or audio sound.
NOTICE
■While the engine oil level warning message is displayed
Continued engine operation with low engine oil will damage the engine.

■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 and turn off the
engine, 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: ILSAC GF-5 multigrade
engine oil
Recommended viscosity: SAE 5W-30 SAE 5W-30 is the best choice for
good fuel economy and good starting
in cold weather.
If SAE 5W-30 is not available, SAE
10W-30 oil may be used. However, it
should be replaced with SAE 5W-30
at the next oil change.

Oil viscosity (5W-30 is explained here
as an example):

• The 30 in 5W-30 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:
The International Lubricant Specifica-

Certification Mark is added to some oil
containers to help you select the oil you
should use.
