781-4. Hybrid system
When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates, your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. (
P.474)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
this case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Do not place objects that will
block the air intake vents. The
hybrid battery (traction battery)
may become limited and be
damaged.
●Clean the air intake vents regu-
larly to prevent the hybrid bat-
tery (traction battery) to be
limited.
●Do not allow liquid or foreign
material to enter the air intake
vent as this may cause a short
circuit and damage the hybrid
battery (traction battery).
●A filter is inst alled to the air
intake vent. When the filter
remains noticeably dirty even
after cleaning the air intake
vent, filter cleaning or replace-
ment is recommended. Refer to
P.439for details on how to clean
the filters.

perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■When the outside rear view
mirror defoggers are operat-
ing
Do not touch the rear view mirror
surfaces when the outside rear
view mirror def oggers are on.

Maintenance and care
Remove the dust from the air
intake vent with a vacuum
cleaner, etc.
Make sure to only use a vacuum to
suck out dust and clogs. Attempting
to blow out dust and clogs using an
airgun, etc. may push it into the air
intake vent. (P.441)
If dust and clogs cannot be com-
pletely removed with the air
intake vent cover installed,
remove the cover and clean the
filter.

remove it.
3 Remove the air intake vent
filter.
Disengage the claw to remove the
filter from the rear scuff plate.
Cleaning the hybrid
batter y (traction bat-
ter y) air intake vents
and filter
To prevent the fuel economy
from being affected, visually
inspect the hybrid battery
(traction battery) air intake
vents periodically for dust
and clogs. If it is dusty or
clogged or if “Maintenance
Required for Traction Bat-
tery Cooling Parts See
Owner’s Manual” is shown
on the multi-information
display, clean the air intake
vent using the following
procedures:

■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 d etails, refer to
“Scheduled Maintenance Guide”.
■Cleaning the air intake vent
●Dust in the air intake vent may
interfere with the cooling of the
hybrid battery (trac tion 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 periodi-
cally.
●Improper handling of the air intake
vent cover and filt er 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 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.439)
●After cleaning the air intake vent,
start the hybrid system and check

Maintenance and care
that the warning message is no
longer shown. It may take approxi-
mately 20 minutes after the hybrid
system is started until the warning
message disappears. If the warn-
ing message does not disappear,
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
vents, make sure to turn the
power switch off to stop the
hybrid system.
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 (tr action battery)
and cause a malfunction.
■To prevent damage to the
vehicle
●Do not allow wa ter or foreign
matter to enter the air intake
vent when the cover is
removed.
●Carefully handle the removed
filter so that i t 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 witho ut the filter
installed.
■If “Maintenance Required for
Traction Battery 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 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.
