■

Scheduled maintenance of the

air intake vent is necessary

when

In some situations such as when the

vehicle is used frequently or in

heavy traffic or dusty areas, the air

intake vent may need to be cleaned

more regularly. For details, refer to

“Scheduled Maintenance Guide” or

“Owner’s Manual Supplement”.

■

Cleaning the air intake vent

●

Dust in the air intake vent 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 vehi-

cle 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

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

Traction Battery Cooling Parts

See Owner’s Manual” is dis-

played on the multi-information

display

●

If this warning message is dis-

played on the multi-information

display, remove the air intake vent

cover and clean the filter.

(



P.440)

●

After cleaning the air intake vent,

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 mes-

sage disappears. If the warning

message does not disappear after

driving for appropriately 20 min-

utes, have the vehicle inspected

by your Toyota dealer.

WARNING

■

When cleaning the air intake

vent

●

Do not use water or other liq-

uids to clean the air intake vent.

If water is applied to the hybrid

battery (traction battery) or

other components, a malfunc-

tion or fire may occur.

●

Before cleaning the air intake

vent, make sure to turn the

power switch off to stop the

hybrid system.

■

When removing the air intake

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

hybrid battery (traction battery)

and cause a malfunction.

■

To prevent damage to the

vehicle

●

Do not allow liquid or foreign

material 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

Traction Battery Cooling

Parts See Owner’s Manual” is

displayed on the multi-infor-

mation display

If the vehicle is continuously

driven with the warning message

(indicating that charging/discharg-

ing of the hybrid battery [traction

battery] may become limited) dis-

played, the hybrid battery (traction

battery) may malfunction. If the

warning message is displayed,

clean the air intake vent immedi-

ately.

Battery precautions

Observe the following precau-

tions. Failure to do so may result

in death or serious injury.

●

Do not swallow the battery.

Doing so may cause chemical

burns.

●

A coin battery or button battery

is used in the electronic key. If a

battery is swallowed, it may

cause severe chemical burns in

as little as 2 hours and may

result in death or serious injury.

●

Keep away new and removed

batteries from children.

●

If the cover cannot be firmly

closed, stop using the electronic

key and stow the key in the

place where children cannot

reach, and then contact your

Toyota dealer.

●

If you accidentally swallow a

battery or put a battery into a

part of your body, get emer-

gency medical attention imme-

diately.

■

To prevent battery explosion

or leakage of flammable liq-

uid or gas

●

Replace the battery with a new

battery of the same type. If a

wrong type of battery is used, it

may explode.

●

Do not expose batteries to

extremely low pressure due to

high altitude or extremely high

temperatures.

●

Do not burn, break or cut a bat-

tery.

NOTICE

■

When replacing the battery

Use a flathead screwdriver of

appropriate size. Applying exces-

sive force may deform or damage

the cover.

■

For normal operation after

replacing the battery

Observe the following precautions

to prevent accidents:

●

Always work with dry hands.

Moisture may cause the battery

to rust.

●

Do not touch or move any other

component inside the remote

■

When replacing light bulbs

Toyota recommends that you use

genuine Toyota products designed

for this vehicle.

Because certain bulbs are con-

nected to circuits designed to pre-

vent overload, non-genuine parts or

parts not designed for this vehicle

may be unusable.

WARNING

■

To prevent system break-

downs and vehicle fire

Observe the following precau-

tions.

Failure to do so may cause dam-

age to the vehicle, and possibly a

fire or injury.

●

Never use a fuse of a higher

amperage rating than that indi-

cated, or use any other object in

place of a fuse.

●

Always use a genuine Toyota

fuse or equivalent.

Never replace a fuse with a

wire, even as a temporary fix.

●

Do not modify the fuses or fuse

boxes.

NOTICE

■

Before replacing fuses

Have the cause of electrical over-

load determined and repaired by

your Toyota dealer as soon as

possible.

Light bulbs

You may replace the follow-
ing bulbs yourself. The diffi-
culty level of replacement
varies depending on the
bulb. If necessary bulb
replacement seems difficult
to perform, contact your
Toyota dealer.

LED light bulbs

The lights other than the front side

If any of the LEDs burn out, take

your vehicle to your Toyota dealer to

have the light replaced.

■

Condensation build-up on the

inside of the lens

In certain situations, such as when

driving in the rain or when washing

the vehicle, condensation may form

on the inner side of the headlight

lens and other lights. As each light

has a ventilation hole, moist air may

enter. If the ambient temperature is

low, condensation may form tempo-

rarily, but it will dissipate as the

inside of the light is warmed up. As

the condensation is due to a phe-

nomenon similar to windows fogging

in the rain, it does not indicate a

malfunction.
Contact your Toyota dealer for more

information in the following situa-

tions:

●

Large drops of water have built up

on the inside of the lens.

●

Water has built up inside the

headlight.
