equipped)
 P.257
■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically. This may also
reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the engine switch
is turned to IGNITION
ON mode .
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Turning “A/C”
on will dehumidify the air from the outlets
and defog the windshield effectively.
●If you turn “A/C” off, the windows may fog
up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.

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.
