Information The values for the Tire Pressure Monitoring (TPM) system may be lost during re-coding of the instrument cluster. If the Tire Pressure Monitoring (TPM) system is reset, the wheel electronics must be re-taught and adapted to the system. Preconditions and procedure for teaching the wheel electronics units: • Vehicle is stationary for at least 5 minutes. • Select the type of tires fitted (type and size) in the TPM menu in the PCM. The message "No monitoring. System is learning from 15 mph (25 km/h)" then appears in the multi-function display. • Drive at a speed of more than 15 mph (25 km/h) - ideally without stopping - until the tire pressure values are displayed (learning time: less than 2 minutes). The system learns the wheel electronics only while driving. Intermediate stops and deviations from the described teaching procedure can result in a much longer learning time. Teaching can be performed during the test drive or later while the customer is driving. Please inform your customer about this if necessary. 16 Replace Cayenne Owner’s Manual with an updated Cayenne Owner’s Manual with order number WKD9Y004xx19 (xx = language code, e.g. 10, 20, 30, etc.).

This also covers all required preliminary work and subsequent work. The working time includes the following activities during control unit programming: • All required steps for starting or finishing programming • Required interaction during a programming sequence • Waiting times until programming starts • Occasionally checking the programming status (twice per programming block) If no further interaction by the service technician is required once control unit programming has started because programming is performed automatically, there is no need for the service technician to remain at the vehicle for the entire programming time. These waiting times are not included in the working time if the total programming time is more than 15 minutes. If programming takes up to 15 minutes, the full waiting time is included in the working time.
