temperature. Contained air temperature is dependent upon several
factors such as rate of tire rotation, tire deflection, amount of braking,
etc. In similar manner, the tire pressure will decrease if the contained air
temperature decreases. For example, if the vehicle is stationary over
night with the outside temperature significantly lower than the daytime
temperature, the tire pressure may decrease approximately 3 psi (20.7
kPa) for a drop of 30° F (16.6° C) in ambient temperature. This lower
pressure value may be detected by the TPMS as being significantly lower
than the cold pressure indicated on your vehicles tire label, and activate
the TPMS warning for low tire pressure. If the low warning light is on,
visually check each tire to verify that no tire is flat. If one or more tires
are flat, repair of fix as necessary. If all tires appear to be inflated,
carefully drive the vehicle to the nearest location where air can be added
to the tires. Turn the ignition to the “off” position. Inflate all the tires to
the recommended cold pressure.
The system uses radio-frequency to monitor the tire pressure on all tires
excluding the spare tire. The sensors transmit the tire pressure readings
to the receiver module located in the vehicle. The receiver module then
electronically transmits the status to the message center. For more tire
warning information, refer to theMessage Centerin theDriver controls
chapter.
This device complies with part 15 of the FCC rules and with RS-210 of
Industry Canada. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) This device
must accept any interference received, including interference that may
cause undesired operation.
The tire pressure monitoring system is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, seeTire
inflation pressurein this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
