2: Driver's and front passenger’s seat belt warning buzzers The driver’s and front passenger’s seat belt warning buzzers sound to alert
the driver and front passenger that his or her seat belt is not fastened. The
buzzer sounds intermittently for 10 seconds after the vehicle has reached a
speed of 12 mph (20 km/h). Then, if the seat belt is still unfastened, the
buzzer will sound at a different tone for 20 more seconds.
Tire pressure warning
light
When the light comes on:
Low tire inflation pressure
such as
• Natural causes ( P. 422)
• Flat tire ( P. 447) Adjust the tire inflation
pressure (including the
spare tire) to the speci-
fied level.
The light will turn off
after a few minutes. In
case the light does
not turn off even if the
tire inflation pressure
is adjusted, have the
system checked by
your Toyota dealer.
When the light comes on
after blinking for 1 minute:
Malfunction in the tire
pressure warning system
( P. 423) Have the system
checked by your
Toyota dealer.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency (for electric vehicles, traction
battery efficiency) and tire tread lif e, and may affect the vehicle's han-
dling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low ti re pressure telltale (tire
pressure warning light).
