as possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
See

warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then

may be an early indicator that the tire
pressures are getting low and the tires
need to be inflated to the proper
pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
