■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.291)
●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.
