To initialize the system, perform the fol-
lowing:
1. Park the vehicle in a safe place and
turn the ignition switch off.
2. Adjust the pressure of all the installed
tires to the specified cold tire inflation
pressure level. (See "Tires" on page
386 in Section 8.)
3. Set the ignition switch to ON.
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 ignition
switch ON, and then turn the ignition
switch off.
If you push the tire pressure reset switch
while the 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.
