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.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 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.

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 ve nts, 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 reinst all 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

Maintenance and care
Tires cannot be rotated.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)
A run-flat tire has a mark on
the sidewall.
Make sure to replace the flat tire before the
vehicle has been driven for near 100 miles
(160 km). Also, do not use a repaired tire.
■Run-flat tires
●The run-flat tires are for only this vehicle.
Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon-
strate the performance of run-flat tires.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.340)

WARNING
●Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those
recommended by Lexus.
●Do not mix differently constructed
tires (radial, bias-b elted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
■Low profile tires (21-inch tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
●Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■If tire inflation pres sure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
