When initializing the system, make sure
the low tire pressure warning light blinks
three times. If the warning light does not
blink three times, initializing will be failed
and the tire pressure warning system will
not function properly.
Do not push the reset switch without ad-
justing the tire inflation pressure to the
specified level. Otherwise, the low tire
pressure warning light may not come on
even if the tire inflation pressure is low,
or it may come on when the tire inflation
pressure is actually normal.
If you push the reset switch while the
vehicle is moving, initialization is not per-
formed.
If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Toyota dealer.
When the warning light blinks twice every
second while driving, you may be unable
to reset the system. In this case, set the
system again according to the above pro-
cedure.
