■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 cont rolled 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
Standard No. 109.
Grades B and A represent higher le vels 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 speed-detecting automatic door lock and shift-linked automatic
door lock are both on, the door lock operates as follows:
• When shifting the shift position to any position other than P, all the doors
will be locked.
• If the vehicle is started with all the doors locked, the Speed linked door locking function would not operate.
• If the vehicle is started with any door unlocked, the Speed linked door locking function will operate.
● 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
(Emergency flashers) function settings.
■ 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.
