When a tire is replaced with a spare tire (vehicles with compact spare
tire)
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat,
the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
 P. 4 9 7
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned to the “ON” position (vehicles
without a smart key system) or IGNI TION ON mode (vehicles with a
smart key system), have it checked by your Toyota dealer.
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 630) However, Toyota recommends that the seat
belt reminder buzzer be operational to alert the driver and front passenger
when seat belts are not fastened.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
