Driving Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation Each tire, including the spare (i f provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire infl ation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tire s is significantly under-inflated.
Accordingly, when the low tire pr essure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-in flated tire caus es the tire to
overheat and can lead to tire fail ure. Under-inflat ion also reduces
fuel efficiency and tire tread li fe, and may affect the vehicle’s
handling and stopping ability. 19 CLARITY PHEV-31TRW6100.book 430 ページ 2018年10月25日 木曜日 午後2時29分
