Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9 12. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low
tire pressure warning light may
appear when the vehicle is
first started and then turn off.
