Cleaning the air intake vent

●

Dust in the air intake vent may

interfere with the cooling of the

DC/DC converter. If the cooling

DC/DC converter becomes lim-

ited, the 12-volt battery may dis-

charge. Inspect and clean the air

intake vent periodically.

●

Improper handling of the air intake

vent cover and filter may result in

damage to them. If you have any

concerns about cleaning the filter,

contact your Toyota dealer.

■

If “Maintenance required for

DCDC converter cooling parts

See Owner’s Manual” is shown

on the multi-information display

●

If this warning message is shown

on the multi-information display,

remove the air intake vent cover

and clean the filter. (



P.516)

●

After cleaning the air intake vent,

start the hybrid system and check

that the warning message is no

longer shown.

It may take approximately 20 min-

utes after the hybrid system is

started until the warning message

disappears. If the warning mes-

sage does not disappear, have

the vehicle inspected by your

Toyota dealer.

WARNING

■

When cleaning the air intake

vent

●

Before cleaning the air intake

vent, make sure to turn the

power switch off to stop the

hybrid system.

●

Do not use water or other liq-

uids to clean the air intake vent.

If water is applied to the DC/DC

converter or other components,

a malfunction or fire may occur.

NOTICE

■

When cleaning the air intake

vent

When cleaning the air intake vent,

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 vent, which may

affect the performance of the

DC/DC converter and cause a

malfunction.

■

To prevent damage to the

vehicle

●

Do not allow water or foreign

matter to enter the air intake

vent when the cover is

removed.

●

Carefully handle the removed

filter so that it will not be dam-

aged. If the filter is damaged,

have it replaced with a new filter

by your Toyota dealer.

●

Make sure to reinstall the filter

and cover to their original posi-

tions after cleaning.

●

Do not install anything to the air

intake vent other than the exclu-

sive filter for this vehicle or use

the vehicle without the filter

installed.

■

If “Maintenance required for

DCDC converter cooling parts

See Owner’s Manual” is

shown on the multi-informa-

tion display

If the vehicle is continuously

driven with the warning message

(indicating that the cooling perfor-

mance/capacity of the DC/DC

converter may become limited)

displayed, the DC/DC converter

may malfunction. If the warning

message is displayed, clean the

air intake vent immediately.
