illuminates, you should stop and adjust
the tire pressure of all four tires to the
recommended COLD tire pressure shown
on the Tire and Loading Information la-
bel located in the driver’s door opening.
The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. Af ter the tire is inflated to the recom-
mended pressure, the vehicle must be
driven at speeds above 16 mph (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire
pressure gauge to check the tire pres-
sure.
The low tire pressure warning light remains
illuminated until the tires are inflated to the
