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.

If a warning message was displayed
on the multi-information display
before cleaning the filters, start the

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
