cannot be expected to function as a tire pressure gauge.
There can be a delay between the instant you adjust the
air pressure in a tire and when the system updates the
display. The TPMS is not intended to provide you with
notification of rapid air loss.
The TPMS will cause the Telltale lamp in the instrument
cluster to illuminate whenever the pressure in one tire
falls 25% below the recommended pressure shown on the
tire label.
NOTE:
A TPMS does not replace normal tire mainte-
nance.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable operation or sensor damage
may result when using replacement equipment that
is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use
aftermarket tire sealant or balance beads as damage
to the sensors may result. The standard TIREFIT
system (see Tirefit Tire Repair and Jacking Instruc-
tions in the What To Do In Emergencies section) is
specifically designed to operate in conjunction with
the TPMS, and will not damage the sensors.
NOTE:
The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPMS setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPMS Telltale lamp on the following day if
