Interior Features
■Temperature control dial
When the mode is set to or with the fan control dial in a position
other than 0 and the temperature control dial in the maximum cold position,
the air intake selector switches to the recirculated air position and the A/C
turns on automatically. If A/C is not desired, press the A/C switch to turn it off.
■ Mode selector dial
●The mode selector dial can be set at the intermediate positions ( )
between each mode. Set the dial to an intermediate position if you want to
split the airflow between the two modes.
● For example, when the mode selector dial is at the position between
the and positions, airflow from the floor vent is less than that of
the position.
■ A/C switch
The air conditioner may not function when the outside temperature
approaches 32 °F (0 °C).
WARNING
■Do not use the recirculated air position in cold or rainy weather
Using the recirculated air position in cold or rainy weather is dangerous as it
will cause the windows to fog up. Your vision will be hampered, which could
lead to a serious accident.

NOTICE
If the air conditioner is used while driving up long hills or in heavy traffic,
monitor the engine coolant temperature warning light to see if it is illumi-
nated or flashing ( →P. 148).
The air conditioner may cause engine overheating. If the warning light is
illuminated or flashing, turn the air-conditioning off ( →P. 496).

WARNING
■Do not defog the windshield using the position with the tempera-
ture control set to the cold position
Using the position with the temperature control set to the cold posi-
tion is dangerous as it will cause the outside of the windshield to fog up.
Your vision will be hampered, which could lead to a serious accident. Set
the temperature control to the hot or warm position when using the
position.

windshield and side windows.Set the mode selector dial to the desired position.
Set the air intake selector to the outside air position.

Turn on the air conditioner by pressing the A/C switch.
One of the functions of the air conditioner is dehumidifying the air and, to use
this function, the temperature does not have to be set to cold. Therefore, set
the temperature control dial to the desired position (hot or cold) and turn on
the air conditioner when you want to dehumidify the cabin air.

YARIS iA_OM_OM99N89z_(U)
If a tire wears evenly, a wear indicator will appear as a solid band
across the tread.
Replace the tire when this happens.New tread
Worn tread
Tread wear indicator
You should replace the tire before the band crosses the entire tread.
With tire pressure monitoring system:
After adjusting the tire pressure, init ialization of the tire pressure mon-
itoring system is necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
Tires degrade over time, even when they are not being used on the road.
It is recommended that tires generally be replaced when they are 6 years
or older. Heat caused by hot climates or frequent high loading conditions
can accelerate the aging process. You should replace the spare tire when
you replace the other road tires due to the aging of the spare tire. The
period in which the tire was manufactured (both week and year) is indi-
cated by a 4-digit number.
Refer to Tire Labeling on P. 530.

WARNING
■Always use tires that are in good condition
Driving with worn tires is dangerous. Reduced braking, steering, and
traction could result in an accident.
■Replace all four tires at the same time
Replacing just one tire is dangerous. It could cause poor handling and
poor braking resulting in loss of vehicle control. Toyota strongly recom-
mends that you replace all four tires at the same time. If you replace
only two tires, the new tires should be installed on the rear of the vehi-
cle.

Customer Information and Reporting Safety Defects
Uniform Tire Quality Grading System
(UTQGS)
This information relates to the tire grading system developed by the
U.S. National Highway Traffic Safety Administration for grading tires
by tread wear, traction, and temperature performance.
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one-and-a-half times as
well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may d epart significantly from the norm
because of variations in driving habits, service practices and differ-
ences in road characteristics and climate.
The traction grades, from highest to lowest, are AA, A, B, and C.
These grades represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete . A tire marked C may have poor
traction performance.
Tread Wear
Traction-AA, A, B, C
WARNING
The traction grade assigned to this tire is based on braking (straight
ahead) traction tests and does not include acceleration cornering (turn-
ing), hydroplaning, or peak traction characteristics.
