691-4. Hybrid system
LS500h_OM_(U)_1809

For safety and security
There are air intake vents on each side
of the rear seatback with the purpose
of cooling the hybrid battery (traction
battery). If the vents become blocked,
hybrid battery output may be reduced. When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact your Lexus dealer.
A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.
■If a warning light comes on, a warning
message is displayed, or the 12-volt bat-
tery is disconnected
The hybrid system may not start. In this
case, try to start the system again. If the
“READY” indicator does not come on, con-

tery) air intake vents
NOTICE
■Hybrid battery (traction battery) air
intake vents
●Make sure not to block the air intake
vent with anything, such as a seat
cover, plastic cover, or luggage. If the
vents become blocked, the hybrid bat-
tery (traction battery) input and output
may be restricted, leading to a reduc-
tion in hybrid battery (traction battery)
output and a malfunction.
●When dust etc. has accumulated in the
air intake vent, periodically clean it
with a vacuum cleaner to prevent the
vent from clogging.
●A filter is installed to the air intake vent.
When the filter remains noticeably
dirty even after cleaning the air intake
vent, filter cleaning or replacement is
recommended. When cleaning or
replacing the filter, contact your Lexus
dealer.
Refer to P.372 for details on how to
clean the filters.
●Do not get water or foreign materials
in the air intake vent s as this may cause
a short circuit and damage the hybrid
battery (traction battery).

Interior features
●When the power switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.
●The doors that can recall the air condi-
tioning setting* when unlocked using the
smart access system with push-button
start can be changed. For details, contact
your Lexus dealer.
*: The doors that can recall the driving
position memory are changed at the
same time.
■Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency:
●Engine speed and compressor operation
controlled to restri ct heating/cooling
capacity
●Fan speed restricted when automatic
mode is selected
To improve air condit ioning performance,
perform the following operations:
●Turn off eco air conditioning mode
( P.326)
●Adjust the fan speed
●Turn off Eco drive mode ( P.297)
■When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when “A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur- ring:
• It is recommended that the air condition- ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short pe riod of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on.
●When parking, the system automatically
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle.
■Using the voice command system
Air conditioning system can be operated
using voice commands. For details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Air conditioning filter
P.408
■Customization
Some functions can be customized.
( P.479)
WARNING
■To prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
■When the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.

Maintenance and care
■Cleaning the air in take vent filters
1 Remove the grille.
2 Remove the filter.
3 Remove any dust and clogs from
the filter using a vacuum cleaner,
etc.
Make sure to also remove dust and clogs
from the inner side of the air intake vent
grille.
If the filter is damaged, have it replaced by
your Lexus dealer.
4Install the filter in its original posi-
tion, and then install the grille. 5
Start the hybrid system and check
that “Maintenance Required for
Traction Battery Cooling Parts See
Owner’s Manual” is no longer dis-
played on the multi-information dis-
play.
It may take approximately 20 minutes after
the hybrid system is started until the warn-
ing message disappea rs. If the warning
message does not disappear, have the
vehicle inspected by your Lexus dealer.
■Scheduled maintenance of the air
intake vent is necessary when
In some situations such as when the vehicle
is used frequently or in heavy traffic or dusty
areas, the air intake vent may need to be
cleaned more regularly.
For details, refer to “Owner’s Manual Sup-
plement” or “Scheduled Maintenance”.
■Cleaning the air intake vents
●If the vehicle is driven with the air intake
vents and filters are clogged, the hybrid
battery (traction battery) may not be
cooled sufficiently, possibly causing an
increase in the fuel consumption and
damage to the hybrid battery (traction
battery).
●Improper handling of the air intake vent
grilles and filters may result in damage to
them. If you have any concerns about
cleaning the filter, contact your Lexus
dealer.
■If “Maintenance Required for Traction
Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-infor-
mation display
●It is possible the air intake vents or filters
are clogged due to accumulated dust.
Clean the air intake vents and filters,
referring to the cleaning method.
●If the vehicle is driven continuously with
this message displayed, the hybrid bat-
tery (traction battery) may not be cooled
sufficiently, which may lead to the driving
distance by the electric motor becoming
shorter and damage to the hybrid battery
(traction battery). Clean the air intake
