6-1. Maintenance and care

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.

Install the filter in its original posi-
tion, and then install the grille.

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.

 Remove dirt using a water-damp-

ened soft cloth or synthetic chamois.

 Wipe the surface with a dry soft

cloth to remove any remaining
moisture.

■

Cleaning the areas with satin-finish

metal accents

The metal areas use a layer of real metal for

the surface. It is necessary to clean them

regularly. If dirty areas are left uncleaned for

long periods of time, they may be difficult to

clean.

 Remove dirt and dust using a vac-

uum cleaner.

 Wipe off any excess dirt and dust

with a soft cloth dampened with
diluted detergent.

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

(traction battery) may malfunction. If the

warning message is displayed, clean the

air intake vents immediately.

formed is under warranty coverage. If any

problem should arise while your vehicle is

under warranty, your Lexus dealer will

promptly take care of it.

General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.

Scheduled maintenance should be
performed at specified intervals

other reproductive harm. Work in a

well ventilated area.

●

Oils, fuels and fluids contained in vehi-

cles as well as waste produced by

component wear contain or emit

chemicals known to the State of Cali-

fornia to cause cancer and birth

defects or other reproductive harm.

Avoid exposure and wash any affected

area immediately.
