2023 TOYOTA PRIUS PRIME flat tire

5227-3. Do-it-yourself maintenance
■Warning performance of the tire
pressure warning system
●When performing the tire pressure
setting using the current tire infla-
tion pressure, the warning timing
of the tire pressure warning sys-
tem will vary according to the con-
ditions under which tire pressure
setting was performed. Therefore,
a warning may be output even if
the tire inflation pressure drops
slightly or if the tire inflation pres-
sure increases above that when
the tire inflation pressure was set.
●Make sure to perform the tire
pressure setting procedure after
adjusting the tire inflation pres-
sure. Also, make su re the tires are
cold before performing the tire
pressure setting procedure or
adjusting the tire inflation pres-
sure.
■Tire inflation pressure setting
procedure
●If the power switch is turned off
while setting the tire inflation pres-
sure, the next time the power
switch is turned to ON, the setting
procedure will resume and it will
not be necessary to restart the
procedure.
●If the tire inflation pressure setting
procedure is started unnecessar-
ily, adjust the tire inflation pres-
sure to the specified level with the
tires cold and then perform setting
by selecting a specified tire infla-
tion pressure, or perform the tire
inflation pressure setting proce-
dure with the current tire inflation
pressure.
■If the tire inflation pressure can-
not be set easily
●Normally, the tire inflation pres-
sure setting procedure can be
completed in 2 or 3 minutes.
●If the tire pressure warning light
does not blink 3 times when start-
ing the tire inflation pressure set-
ting procedure, the procedure may not have started.
Perform the procedure again from
the beginning.
●If tire inflation
pressure setting
procedure cannot be completed
after performing the above proce-
dure, contact your Toyota dealer.
The tire pressure warning valve
and transmitter is equipped with
a unique ID code. When new
tire pressure warning valves and
transmitters are installed, new
ID codes must be registered in
the tire pressure warning com-
puter.
• ID codes can be registered by
yourself, but depending on
the driving conditions and
driving environment, registra-
tion may take some time to
complete.
• When using a wheel set which all of the ID codes have
already been registered, the
wheel set can be changed in
a short amount of time.
Before performing ID code reg-
istration, make sure that no
wheels with tire pressure warn-
ing valve and transmitters
installed are near the vehicle.
1 Park the vehicle in a safe
place, turn the power switch
off and wait 15 minutes or
more.
2 Start the hybrid system.

WARNING
■Replacing a flat tire
●Do not touch the disc wheels or
the area around the brakes
immediately after the vehicle
has been driven.
After the vehicle has been
driven the disc wheels and the
area around the brakes will be
extremely hot. Touching these
areas with hands, feet or other
body parts while changing a tire,
etc. may result in burns.

5307-3. Do-it-yourself maintenance
1Remove any dirt or foreign
matter from the wheel con-
tact surface.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while th e vehicle is in
motion, causing the tire to come off.
2 Install the tire and loosely
tighten each wheel nut by
hand by approximately the
same amount.
Turn the wheel nuts until the wash-
ers ( ) come into contact with the
disc wheel ( ).
WARNING
●Failure to follow these precau-
tions could cause the wheel
nuts to loosen and the tire to fall
off, resulting in death or serious
injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the
wheel nuts to be excessively
tightened, leading to bolt or disc
wheel damage. Remove any oil
or grease that has adhered
when installing the wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf
(103 N•m, 10.5 kgf•m) as soon
as possible after changing
wheels.
• After replacing a tire, check the tightening torque as soon as
possible. If you cannot confirm
the tightening torque yourself,
have the vehicle inspected at
your Toyota dealer.
• When installing a tire, only use wheel nuts that have been spe-
cifically designed for that wheel.
• If there are any cracks or defor- mations in the bolt screws, nut
threads or bolt holes of the
wheel, have the vehicle
inspected by your Toyota
dealer.
• Do not attach a heavily dam- aged wheel ornament, as it may
fly off the wheel while the vehi-
cle is moving.
■Replacing a flat tire for vehi-
cles with power back door
In cases such as when replacing
tires, make sure to cancel the
power back door system
(  P.202). Failure to do so may
cause the back door to operate
unintentionally if the power back
door switch is accidentally
touched, resulting in hands and
fingers being caught and injured.
