Tire pressure warning reset switch
25p122
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.

When rotating the tires on vehicles dif-
fering with front and rear tire inflation
pressures.

When changing the tire size.
To initialize the system, perform the fol-
lowing:
1. Park the vehicle in a safe place and
the hybrid system is off.
2. Adjust the pressure of all the installed
tires to the specified cold tire inflation
pressure level.(See “Tires” on page
429.)
3. Turn the “POWER” switch is selected
in “IG − ON” mode.
4. Push and hold the tire pressure warn-
ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for a few minutes with the “POW-
ER” switch is selected in “IG − ON”
mode, and then turn the hybrid system
is off.
If you push the tire pressure reset switch
while vehicle is moving, initialization is not
performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.

If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Toyota dealer.
