Reset Procedure
TPM Tire Pressure Monitor
The Concept
TPM controls the tire inflation pressure in the four mounted wheels. The system notifies you if the tire inflation pressure has fallen significantly in one or more tires.
Functional Requirement
To ensure the reliable signaling of a flat tire, the system must be reset at the correct tire inflation pressure.
Always use wheels equipped with TPM electronics, including a metal valve; otherwise, there is no guarantee that the system will function properly.
NOTE: The system must be reset after every correction of tire inflation pressure and after every tire or wheel change.
System Limits
CAUTION! TPM cannot warn you of sudden, serious tire damage due to external factors.
The system does not function properly if it has not been reset, e.g. it may identify a tire as flat in spite of the fact that the tire is filled to the correct inflation pressure.
The system is deactivated and is unable to detect flat tires if a wheel not equipped with TPM electronics has been mounted, e.g. a compact wheel, or if TPM is experiencing temporary interference from other systems or devices that use the same frequency.
Resetting System
NOTE: The system must be reset after every correction of tire inflation pressure and after every tire or wheel change.
1. Start engine, but do not begin to drive.
2. Press the button until the yellow warning lamp in the instrument cluster lights up for a few seconds.
3. Begin driving.
After a few minutes of driving, the tire inflation pressures in the tires are adopted as the desired values to be monitored. The resetting is completed during driving and can be interrupted at any time without requiring any input from you. The resetting automatically continues when driving resumes.
Low Tire Pressure Message
The warning lamp lights up yellow. In addition, a signal sounds. You have a flat tire or a significant loss of tire pressure in one or more tires.
1. Reduce speed and stop the vehicle carefully. Avoid sudden braking and steering maneuvers.
2. Identify the damaged wheel or wheels.
3. Replace the damaged wheel.
4. Check tire inflation pressure and correct as needed.
The compact wheel is not equipped with the required TPM electronics and is not monitored when mounted.
When driving with the compact wheel, the system indicates a malfunction. Have the damaged tire replaced.
Malfunction
The yellow warning lamp flashes and then lights up continuously. Flat tires cannot be detected.
Such a message is displayed in the following
situations:
- When a malfunction is occurring:
Have the system checked
- When a wheel without TPM electronics is mounted, e.g. a compact wheel
- When TPM is experiencing temporary interference from other systems or devices that use the same frequency
