6-1. Maintenance and care
3
Remove 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.
4
Install 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 motor) 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 differ 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.279)
●
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 disappears. If the warn-
ing message does not disappear after
driving for appropriately 20 minutes,
have the vehicle inspected by your Lexus
dealer.
WARNING
■
When cleaning the hybrid battery
(traction battery) air 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.

NOTICE
■
When cleaning the air intake vents
When cleaning the air intake vents, make
sure to only use a vacuum to suck out
dust and clogs. If a compressed air blow
gun, etc. is used to blow out dust and
clogs, the dust or clogs may be pushed
into the air intake vents, which may affect
the performance of the hybrid battery
(traction battery) and cause a malfunc-
tion.
■
To prevent damage to the vehicle
●
Do not allow water or foreign matter to
enter the air intake vents when the
cover is removed.
●
Carefully handle the removed filters so
that it will not be damaged.
If the filters are damaged, have them
replaced with new filters by your Lexus
dealer.
●
Make sure to reinstall the filters and
cover to their original positions after
cleaning.
●
Do not install anything to the air intake
vents other than the exclusive filters for
this vehicle or use the vehicle without
the filters installed.
■
If “Maintenance required for traction
battery cooling parts See owner’s
manual” is displayed on the multi-
information display
If the vehicle is continuously driven with
the warning message (indicating that
charging/discharging of the hybrid bat-
tery [traction battery] may become lim-
ited) displayed, the hybrid battery
