Tire Monitoring System: Service and Repair




If a low tire pressure warning light is observed, inflating the tire(s) to specified pressures and pushing the "clear" button will shut the light off.

- The warning messages are cleared and removed from SID using the Clear button on the instrument panel.

- If the fault condition remains, the message will be displayed at start-up until the problem is fixed.

- With an "Alarm" message, only the message text can be deleted while the fault symbol is displayed until the fault is dealt with.
