Maintenance of the tires

Each tire, including the spare (if 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 (tire and load information label).

(If your vehicle has tires of a different size than the size indicated on the vehicle

placard or tire inflation pressure label [tire and load information label], you should

determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure

monitoring system (TPMS-tire pressure warning system) that illuminates a low tire

pressure telltale (tire pressure warning light) when one or more of your tires is sig-

nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-

sure warning light) illuminates, you should stop and check your tires as soon as

possible, and inflate them to the proper pressure. Driving on a significantly under-

inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation

also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling

and stopping ability.

Please note that the TPMS (tire pressure warning system) is not a substitute for

proper tire maintenance, and it is the driver’s responsibility to maintain correct tire

pressure, even if under-inflation has not reached the level to trigger illumination of

the TPMS low tire pressure telltale (tire pressure warning light).
