Low tire pressure warninglight
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors the
tire pressure of all tires except the spare.
The low tire pressure warning light warns of
low tire pressure or indicates that the TPMS
is not functioning properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1 sec-
ond and turns off.
Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
“Tire Pressure Low - Add Air” warning also
appears in the vehicle information display. When the low tire pressure warning light il-
luminates, you should stop and adjust the
tire pressure of all four tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located in
the driver’s door opening. The low tire pres-
sure warning light does not automatically
turn off when the tire pressure is adjusted.
After the tire is inflated to the recommended
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 pressure.
The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains illumi-
nated.
