This  information  has  been  prepared  in  accordance  with  regulations
issued  by  the  National  Highway  Traffic  Safety Administration  of  the
U.S. Department of Transportation.
It  provides  the  purchasers  and/or  prospective  purchasers  of  Toyota
vehicles with information on uniform tire quality grading.

Your Toyota  dealer  will  help  answer  any  questions  you  may  have  as

you read this information.

■

DOT quality grades

All passenger vehicle tires must conform to Federal Safety Require-
ments  in  addition  to  these  grades.  Quality  grades  can  be  found
where applicable on the tire sidewall between tread shoulder and
maximum section width.

For example: Treadwear 200 Traction AA Temperature A

■

Treadwear

The  treadwear  grade  is  a  comparative  rating  based  on  the  wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.

For example, a tire graded 150 would wear one and a half (1 - 1/2)

times as well on the government course as a tire graded 100.

The  relative  performance  of  tires  depends  upon  the  actual  condi-

tions of their use. Performance may differ significantly from the norm

due to variations in driving habits, service practices and differences

in road characteristics and climate.

■

Traction AA, A, B, C

The  traction  grades,  from  highest  to  lowest,  are AA, A,  B  and  C,
and  they  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.
Warning: The traction grade assigned to this tire is based on braking

(straight ahead) traction tests and does not include cornering (turn-

ing) traction.

Uniform Tire Quality Grading

562

8-1. Specifications

■

Temperature A, B, C

The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate  heat  when  tested  under  controlled  conditions  on  a  specified
indoor laboratory test wheel.

Sustained  high  temperature  can  cause  the  material  of  the  tire  to

degenerate and reduce tire life, and excessive temperature can lead

to sudden tire failure.
Grade C corresponds to a level of performance which all passenger

car  tires  must  meet  under  the  Federal  Motor  Vehicle  Safety  Stan-

dard No. 109.
Grades B and A represent higher levels of performance on the labo-

ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly

inflated and not overloaded.

Excessive speed, underinflation, or excessive loading, either sepa-

rately  or  in  combination,  can  cause  heat  buildup  and  possible  tire

failure.

When  the  speed-detecting  automatic  door  lock  function  and  shift  position
linked door locking function (shifting gears to a position other than P locks
all doors) are both on, the door lock operates as follows.

• When shifting the shift lever to any position other than P, all the doors will

be locked.

• If the vehicle is started with all the doors locked, the speed-detecting auto-

matic door lock function would not operate.

• If  the  vehicle  is  started  with  any  the  door  unlocked,  the  speed-detecting

automatic door lock function will operate.

●

When the doors remain closed after unlocking the doors and the automatic
door lock function (Time elapsed before the automatic door lock function is
activated if a door is not opened after being unlocked) activates, the signals
will  be  generated  in  accordance  with  operation  signal  (buzzers)  and  the

WARNING

■

During customization

As  the  engine  needs  to  be  running  during  customization,  ensure  that  the
vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may
collect and enter the vehicle. This may lead to death or serious health haz-
ard.

NOTICE

■

During customization

To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.

you, your dealer, or Toyota Motor Sales, U.S.A., Inc.
