HIGHLANDER_U (OM48A12U)
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.

HIGHLANDER_U (OM48A12U)■
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.

■Vehicle customization
●When the smart key system is off, the entry unlock function cannot be cus-
tomized.
● When the doors remain closed after unlocking the doors and the timer acti-
vated automatic door lock function activates, signals will be generated in
accordance with the operation buzzer volume and operational signal (Emer-
gency flashers) function settings.
■ Changing of the power back door opening angle (if equipped)
The opening angle setting can be changed through operation of either the
power back door switch or the audio system screen.
However, if the engine switch is on and the power back door switch is used to
change the opening angle setting, the changed opening angle will not be
reflected on the audio system screen until the engine switch is turned off and
then on again.
■ When customizing on the audio system screen
Stop the vehicle in a safe place, apply the parking brake, and shift the shift
lever to P. Also, to prevent battery discharge, leave the engine running while
customizing the features.
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 a serious health
hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.
