Vehicles with a tire inflation pressure display function
●In the following situations, initialization may take longer than usual to be
completed or may not be possible. (Usually, the vehicle will need to be
driven for approximately 10 to 30 mi nutes to complete initialization.)
If initialization is not complete af ter driving approximately 30 minutes,
continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to com-
plete initialization.
• If the vehicle is backed up while performing initialization, data col-
lected during initialization will be cleared and it will take longer than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other vehicles are driven close by, it may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your vehicle
over those of other vehicles.
If initialization is not complete after driving for approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
drive the vehicle again.
●In the following situations, initialization will not be started or was not
completed properly and the system w ill not operate properly. Perform
the initialization procedure again.
• If, when attempting to start initializ ation, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven for about 20 minutes after per-
forming initialization, th e tire pressure warning light blinks for approxi-
mately 1 minute and then illuminates.
●If initialization cannot be complet ed after performing the above proce-
dure, contact your Toyota dealer.
■When registering ID codes (vehicles with a tire inflation pressure dis-
play function)
●Before performing ID code registrati on, make sure that no wheels with
tire pressure warning valve and transmitters installed are near the vehi-
cle.
●Make sure to initialize the tire pressure warning system after registering
the ID codes. If the system is initia lized before registering the ID codes,
the initialized va lues will be invalid.
●As the tires will be warm when regist ration is completed, make sure to
allow the tires to cool befo re performing initialization.

Maintenance and care
■Canceling ID code registration (vehicles with a tire inflation pressure
display function)
●To cancel ID code registration afte r it has been started, turn the power
switch off before driving the vehicle.
If the vehicle is driven after ID code registration is started, to cancel reg-
istration, perform the ID code regist ration start procedure again and turn
the power switch off before driving.
●If ID code registration has been canceled, the tire pressure warning light
will blink for approximately 1 minute when the power switch is turned to
ON mode and then illuminate. The tire pressure warning system will be
operational when the tire pressure warning light turns off.
●If the warning light does not turn off even after several minutes have
elapsed, ID code registration may not have been cancelled correctly. To
cancel registration, perform the ID code registration start procedure
again and then turn the power switch off before driving.
■If ID codes are not registered properly (vehicles with a tire inflation
pressure display function)
●In the following situations, ID code registration may take longer than
usual to be completed or may not be possible. (Usually, the vehicle will
need to be driven for approximately 10 to 30 minutes to complete ID
code registration.)
If ID code registration is not complete after driving for approximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer than normal to comple te registration.
• If the vehicle is backed up while performing registration, data col- lected during registration will be cleared, and it will take longer than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other vehicles are driven close by, it may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your vehicle
over those of other vehicles.
• If a wheel with a tire pressure wa rning valve and transmitter installed
is inside or near the vehicle, registration of the ID codes for the
installed wheels may not be possible.
If ID registration is not complete after driving for approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
perform the ID code registration procedure again.

4506-3. Do-it-yourself maintenance
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. Attempt-
ing to blow out dust and clogs
using an airgun, etc. may push it
into the air intake vent. (→P. 454)
If dust and clogs cannot be comple tely removed with the air intake
vent cover installed, remove the cover and clean the filter.
Turn the power switch off.
Using a Phillips screwdriver,
remove the clip.
Cleaning the hybrid battery (traction bat-
tery) air intake vent and filter
To prevent an increase in fuel consumption, visually inspect the
hybrid battery (traction battery) air intake vent periodically for
dust and clogs. If it is dusty or clogged or if “Maintenance
Required for Traction Battery Cooling Parts See Owner’s Man-
ual” is displayed on the multi-in formation display, clean the air
intake vent using the following procedures:

Maintenance and care
■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 regu\
-
larly. For details, refer to “Schedule 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 the hybrid battery (traction battery) overheats, the dis-
tance that the vehicle can be driven using the electric motor (traction motor)
may be reduced and the fuel consumption may increase.
Inspect and clean the air intake vent periodically.
● Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.
■ If “Maintenance Required for Tracti on Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-information display
● If this warning message is displayed on the multi-information display,
remove the air intake vent cover and clean the filter. (→P. 450)
● 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 befor e the warning message disappears. If
the warning message does not disappear after driving for appropriately 20
minutes, have the vehicle inspected by your Toyota dealer.
WARNING
■When cleaning the air intake vent
Do not use water or other liquids to clean the air intake vent. If water is
applied to the hybrid battery (traction battery) or other components, a mal-
function or fire may occur.
■
When removing the air intake vent cover
Do not touch the service plug located near the air intake vent. ( →P. 80)

NOTICE
■When cleaning the air intake vent
■ 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 damaged.
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 positions after
cleaning.
● Do not install anything to the air intake vent other than the exclusive 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-information display
If the vehicle is continuously driven with the warning message displayed,
the hybrid battery (traction battery) may overheat, possibly causing a mal-
function. If the warning message is displayed, clean the air intake vent
immediately.
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 malfunc-
tion.
