Using Keyless Entry System

  1. Turn ignition switch to ON position, with engine off. Apply parking brake.
    NOTE: If learn mode cannot be enabled, TPM system is not enabled in DIM. See appropriate manufacturer service information.
  2. Using keyless entry transmitter, lock and unlock vehicle doors 3 times in order to synchronize transmitter with the receiver.
  3. Simultaneously press the keyless entry transmitter's lock and unlock buttons until a horn chirp sounds, indicating the learn mode has been enabled.
    WARNING: Overinflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure, DO NOT exceed the maximum inflation pressure as noted on the tire sidewall.
    NOTE: If a horn chirp does not sound after 35 seconds for any of the 4 sensors, turn switch to OFF position to exit the learn mode. Repeat the procedure from step  1.
  4. Starting with left front tire, increase or decrease the pressure for 5-8 seconds, or until a horn chirp sounds. The horn chirp may occur before the 5-8 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 5-8 second pressure increase/decrease time period has been reached.
  5. After horn chirp has sounded, repeat procedure for the next 3 sensors in the following order: Right Front, Right Rear, Left Rear.
  6. After left rear sensor has been learned, a double horn chirp will sound, indicating all 4 sensor IDs have been learned. Turn ignition switch to OFF position. Adjust all tire pressures to specification.
