WARNING
■
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a
tire bursts or if sudden air leakage occurs.
■ When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
●Make sure to install 4 tires that are of the specified size, and that all 4 tires
are the same size, same maker, same brand and tread pattern.
● Do not use tire sizes other than those recommended by Toyota.
● Only use radial tires.
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■ When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the 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.

*: Driver's and front passenger’s seat belt buzzer:
The driver’s and front passenger’s seat belt buzzer sounds to alert the driver
and front passenger that his or her s eat belt is not fastened. The buzzer
sounds for 30 seconds after the vehicle has reached a speed of at least 20
km/h (12 mph). Then, if the seat belt is still unfastened, the buzzer will sound
in a different tone for 90 more seconds.
■ Front passenger detection sensor and passenger seat belt reminder
and warning buzzer
●If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and warning
buzzer to sound, even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing
the tire pressure warning reset switch will not turn off the tire pressure warn-
ing light.
■ The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as
natural air leaks or tire inflation pressure changes caused by temperature. In
this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
