661-4. Hybrid system
There are air intake vents under the 
rear seats for the purpose of cooling 
the hybrid battery (traction battery). If 
the vents become blocked, the hybrid 
battery input and output may be 
restricted, leading to a reduction in 
hybrid battery (traction battery) out-
put.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.
NOTICE
■Hybrid battery (traction battery)
Do not carry large amounts of water 
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid battery 
(traction battery),  the battery may be 
damaged. Have the vehicle inspected by 
your Lexus dealer.
Hybrid battery (traction bat-
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.
●Filters are installed to the air intake 
vent. When the filters remain notice-
ably dirty even after cleaning the air 
intake vent, filter cleaning or replace-
ment is recommended. When clean-
ing or replacing the filters, contact 
your Lexus dealer. 
Refer to P.283 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).

2545-3. Using the air conditioning system
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing 
dirty air from entering the vehicle interior 
and helping to cool the vehicle when the 
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch de pending on the tem-
perature setting or the inside 
temperature.
■Registering air condit ioning settings to 
electronic keys
●Unlocking the vehicle using an electronic 
key and turning the engine switch 
conditioning settings.
●When the engine switch 
is turned off, the current air conditioning 
settings will automatically 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 the 
passenger 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 posi-
tion 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.255)
●Adjust the fan speed
●Turn off Eco drive mode ( P.216)
■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 fresh air intake mode to 
encourage better air circulation through-
out 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 SYSTEM OWNER’S 
MANUAL”.

2846-1. Maintenance and care
3Remove dust using a vacuum 
cleaner etc. to clean the filter.
Also, remove dust on the grille as well as on 
the filter using a vacuum cleaner.
4Install the filter in its original posi-
tion, and then install the grille.
5 Start the hybrid system and check 
that the warning message on the 
multi-information display disap-
pears.
It may take several minutes before the 
warning message disappears.
■Scheduled maintenance of the air 
intake filters is  necessary when
In some situations such as when the vehicle 
is used frequently or in  heavy traffic or dusty 
areas, the air intake filters may need to be 
cleaned more regularly.
For details, refer to  “Owner’s Manual Sup-
plement” or “Scheduled Maintenance”.
■Air intake vents maintenance
●If the vehicle is driven with the air intake 
vents clogged, charging/discharging of 
the hybrid battery (traction battery) may 
become limited and the fuel consumption 
may increase.
●Depending on the conditions under 
which the vehicle is used, the air intake 
vents may need to be cleaned more reg-
ularly.
■Cleaning the air intake vents
●Dust in the air intake  vents may interfere 
with the cooling of the hybrid battery 
(traction battery). If  charging/discharging  of the hybrid battery (traction battery) 
becomes limited, the distance that the 
vehicle can be driven using the electric 
motor (traction moto
r) may be reduced 
and the fuel economy may be reduced.
Inspect and clean the air intake vents 
periodically.
●Improper handling may result in damage 
to the air intake vent covers or filters. If 
you have any concerns about cleaning 
the filters, contact your Lexus dealer.
●The necessary cleaning interval of the air 
intake vents will diff er according to the 
vehicle usage environment.
■If “Maintenance required for Traction 
battery cooling parts See owner’s man-
ual” is displayed on the multi-informa-
tion display
●If this warning message is displayed on 
the multi-information display, remove the 
air intake vent covers and clean the filters. 
(  P.283)
●After cleaning the air intake vents, start 
the hybrid system and check that the 
warning message is no longer displayed.
After the hybrid system  is started, it may 
be necessary to drive the vehicle up to 
approximately 20 minutes before the 
warning message disapp ears. If the warn-
ing message does not disappear after 
driving for appropri ately 20 minutes, 
have the vehicle inspected by your Lexus 
dealer.
WARNING
■When cleaning the hybrid battery 
(traction battery) ai r intake vents/fil-
ters
●Do not use water or other liquids to 
clean the air intake vents/filters. If 
water is applied to  the hybrid battery 
(traction battery) or other compo-
nents, a malfunction or fire may occur.
●When the air intake vent covers (under 
the both sides of the rear seat) are to 
be removed, make sure to turn the 
power switch off to stop the hybrid sys-
tem.

or equivalent to satisfy the following 
grade and viscosity.
