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

electric cooling fan may automatically 
start to run if the air conditioning is on 
and/or the coolant temperature is high. 
(  P.309)
■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

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.

●If any of the following messages is shown on the multi-information display, 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”
●If any of the following messages is shown on  the multi-information display, the vehicle may 
have run out of fuel. Stop the vehicle in a safe place and, if the fuel level is low, refuel the 
vehicle. ( P.65)
• “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.369) 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.291 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.

■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

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.Outside temperature
Oil viscosity (5W-30 is explained here 
as an example):
• The 5W in 5W-30 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 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-
tion Advisory Committee (ILSAC) 
Certification Mark is added to some oil 
containers to help you select the oil you 
should use.
