TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor (TPM) system uses wireless
technology to monitor tire pressure levels. Sensors
mounted to each wheel as part of the valve stem transmit
tire pressure readings to a receiver located inside the
vehicle.
NOTE:
The TPM system can inform you about a low
tire pressure condition, but it does not replace normal tire
maintenance. The TPM system is not intended to provide
you with notification of rapid tire pressure loss.
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure gauge.
After adjusting the air pressure in a tire, there will be
a delay before the system updates the display.
The TPM system will cause the indicator lamp in the
instrument cluster to illuminate whenever the pressure in
one tire falls 25% below the recommended pressure
shown on the vehicle’s tire label.
NOTE:
The pressure in your tires changes with temperature.
A significant decrease in temperature could
reduce cold inflation pressure below the TPM setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPM indicator lamp on the following day
if the temperature is very cold. ALWAYS check the
pressure in your tires if the TPM lamp is illuminated.
CAUTION!
The TPM system has been optimized for the original
equipment tires and wheels. TPM system 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.
Aftermarket wheels can cause sensor damage. Do
not use aftermarket tire sealant or balance beads, as
damage to the sensors may result.
NOTE:
The standard TIREFIT system (refer to What To
Do In Emergencies for more information) is specifically
designed to operate in conjunction with the TPM system,
and will not damage the sensors.
If your tire pressure is low, you should correct your tire
inflation pressure as soon as possible and inspect all of
your tires. Low tire pressure will cause the tire pressure
light to illuminate and the alert will sound. They will
remain on for the rest of the driving cycle, or until the tire
pressure is corrected.
In addition to monitoring tire pressures, the TPM system
also monitors faults within the system. If the TPM light
and alarm continue after the tire pressure has been
corrected, see your authorized dealer.
