■
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.
(
●
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

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.

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

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

When replacing light bulbs
Toyota recommends that you use

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.

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.

If the door can not be opened,
open the window using the
power window switch and
ensure an escape route.
If the window can be opened,
exit the vehicle through the

If the door and window cannot
be opened due to the rising
water, remain calm, wait until
the water level inside the
vehicle rises to the point that
the water pressure inside of
the vehicle equals the water
pressure outside of the vehi-
cle and then open the door
after waiting for the rising
water to enter the vehicle, and
exit the vehicle. When the
outside water level exceeds
half the height of the door, the
door cannot be opened from
the inside due to water pres-
sure.
■
Water level exceeds the floor
When the water level exceeds the
floor and time has passed, the elec-
trical equipment will get damaged,
the power windows will not operate,
the engine and motor stop, and the
vehicle may not be able to get mov-
ing.
