2-8. Driving Tips
Hazardous Driving
When driving on ice or in water, snow, mud, sand, or similar hazards:• Be cautious and allow ex tra distance for braking.
• Avoid sudden braking and sudden maneuvering.
• Do not pump the brakes. Continue to press down on the brake pedal. Refer to Antilock Brake System (ABS) on P. 193.
• If you get stuck, select a lower g ear and accelerate slowly. Do not
spin the front wheels.
• For more traction in starting on slippery surfaces such as ice or packed snow, use sand, rock salt, chains, carpeting, or other non-
slip material under the front wheels.
Use snow chains only on the front wheels.
WARNING
■ Be extremely careful if it is n ecessary to downshift on slippery sur-
faces
Downshifting into lower gear while driving on slippery surfaces is danger-
ous. The sudden change in tire speed could cause the tires to skid. This
could lead to loss of vehicle control and an accident.

3-6. ABS/TCS/DSC
Traction Control System (TCS)
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
To turn off the TCS, press the DSC OFF switch ( →P. 197).
The Traction Control System (TCS) enhances traction and safety
by controlling engine torque and braking. When the TCS detects
driving wheel slippage, it lowers engine torque and operates the
brakes to prevent loss of traction.
This means that on a slick surface, the engine adjusts automati-
cally to provide optimum power to the drive wheels, limiting
wheel spin and loss of traction.
WARNING
■ Do not rely on the Traction Control System (TCS) as a substitute for
safe driving
The Traction Control System (TCS) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
■ Use snow tires or tire chains and drive at reduced speeds when roads
are covered with ice and/or snow
Driving without proper traction devices on snow and/or ice-covered roads is
dangerous. The Traction Control System (TCS) alone cannot provide ade-
quate traction and you could still have an accident.

4425-3. Owner Maintenance
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.

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.

Customer Information and Reporting Safety Defects
■Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
■Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
■Tread Wear, Traction and Temperature Grades
● Tread wear: The tread wear grade is a comparative rating based
on the wear rate of the tire wh en tested under controlled condi-
tions on a specified government te st course. For example, a tire
graded 150 would wear one and one-half (1 1/2) times as well on
the government course as a tire graded 100.
● Traction: The traction grades, from highest to lowest are AA, A,
B, and C. The grades represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on specified
government test surfaces of as phalt and concrete. A tire marked
C may have poor traction performance.
● Temperature: The temperature grades are A (the highest), B and
C, representing the tire’s resist ance to the generation of heat and
its ability to dissipate heat w hen tested under controlled condi-
tions on a specified indoor laboratory test wheel.
■Snow Tires
In some heavy snow areas, local governments may require true
snow tires, those with very deeply cut tread. These tires should only
be used in pairs or placed on all four wheels. Make sure you pur-
chase snow tires that are the same size and construction type as
the other tires on your vehicle.
■SAFETY WARNING
The following safety warning appears on the tire’s sidewall. SERI-
OUS INJURY MAY RESULT FROM: • EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH TIRE DIAMETER TO RIM DIAMETER;
NEVER EXCEED 40 psi (275 kPa) TO SEAT BEADS-ONLY
SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
• TIRE FAILURE DUE TO UNDE R-INFLATION/OVERLOADING/
DAMAGE-FOLLOW OWNER’S MANUAL AND PLACARD IN
VEHICLE-FREQUENTLY CHECK INFLATION PRESSURE AND
INSPECT FOR DAMAGE.
