SAFETY 269 driven for up to 10minutes above 15mph (24km/h) in order for the TTPMS to receive the trailer tire pressure information. NOTE: The vehicle may not be driven until the pairing process is complete. Tire Fill Alert — If Equipped NOTE: It is not required to have the engine running to enter Tire Fill Alert mode. The hazard lamps will come on to confirm the vehicle is in Tire Fill Alert mode. A “Trailer Tire Pressure System Not Configured” message will be displayed in the instrument cluster on the TTPMS instrument cluster graphic when a trailer number is selected that has not had trailer tire pressure sensors paired Ъ page189.
Trailer Tire Pressure System Not Configured This feature notifies the user when the placard tire pressure is attained while inflating or deflating the tire. If the hazard lamps do not come on while inflating the tire, the TPMS sensor may be in a null spot preventing the TPMS sensor signal from being received. In this case, the vehicle may need to be moved either forward or backward slightly to exit the null spot. The customer may choose to disable or enable the Tire Fill Alert feature through use of the customer settings in the radio.
Trailer Sensors Detected Do Not Match Active Trailer The “Trailer Sensors Detected Do Not Match Active Trailer” message will be displayed in the instrument cluster when the trailer sensors being received by the TTPMS module do not match the trailer sensors paired to the current trailer number selected. This message will be displayed when the sensors being received completely match the sensors paired to another trailer number configured in the TTPMS module. NOTE: The Tire Fill Alert feature disables every time the ignition is placed in the OFF position. The feature must be re-enabled through the radio each time the ignition is placed back in the ON/RUN position Ъ page189.
When Tire Fill Alert mode is entered, the tire pressure display screen will be displayed in the instrument cluster. Operation: 6 The horn will chirp once to let the user know when to stop filling the tire, when it reaches recommended pressure. NOTE: Only one tire can be filled at a time when using the Tire Fill Alert system. To correct this condition, the correct trailer number must be selected in the radio Ъ page189. The Tire Fill Alert feature cannot be entered if an existing TPMS fault is set to “active” or if the system is in deactivation mode (if equipped).
The horn will chirp three times if the tire is over filled and will continue to chirp every five seconds if the user continues to inflate the tire. The horn will chirp once again when enough air is let out to reach proper inflation level. The TTPMS may have difficulty transmitting through steel-walled tires or on trailers longer than 30ft. It is recommended to use standard tires and trailers less than 30ft long to avoid dropouts or difficulty when pairing. System Limitations The system will be activated when the TPMS receiver module detects a change in tire pressure. The ignition must be in the RUN mode, with the transmission in PARK (P).
The horn will also chirp three times if the tire is then underinflated and will continue to chirp every five seconds if the user continues to deflate the tire.
