Notice: Driving when a TPM system alert or warning condition is detected, may cause tire damage. This damage would not be covered by the vehicle warranty. Reduce vehicle speed to an appropriate safe level and proceed to a safe stopping location or facility where the tire can be inspected and serviced.

The alerts and warnings are as follows:

    • The pressure deviation alert indicates that the pressure has dropped a selected amount below the required pressure for that level of tire temperature.
    • The low pressure warning indicates that the air pressure has dropped to a selected minimum.
    • The high temperature warning indicates that the contained air temperature has exceeded the selected maximum. A tire temperature buildup can be caused by a number of factors including severe under inflation, hard sustained braking, vehicle overload and sustained high speeds

Gage Function

When power is applied to the receiver, the gage display momentarily turns on all icons, beeps, and the gage backlight blinks once. The unit then goes into standby mode waiting for data from the wheel transmitters.

Note: Until the vehicle is in motion no data will be received from any installed transmitter. The display will remain blank.

The gage display has an energy saving feature that turns lights on to full intensity or active stage only when required to display alert conditions or program the unit. The gage automatically switches to low power stage when no control activity is detected.

The respective tire icon is filled in as soon as data from its transmitter is received. The windshield/louver is shown for any towing vehicle transmitter. After data from all transmitters is received the display will be in the state shown or normal mode until an alert or warning condition is detected.

Data from a towed vehicle or trailer (if equipped with sensors) is indicated by tire icons with no windshield/louver icon.
