**Programming with Recognized Transmitters (Keyless Access Vehicles Only):**
1. Remove the key from a recognized transmitter.
2. Place the recognized transmitters in the cup holder or passenger seat.

4. Place the new transmitter in the transmitter pocket/insert.
5. Press the ENGINE START/STOP button. When the transmitter is learned, the DIC display will indicate readiness to program the next transmitter.
6. Remove the transmitter from the pocket and press unlock or lock. Repeat Steps 4–6 for additional transmitters. Press and hold the ENGINE START/STOP button for approximately 12 seconds to exit programming mode.
7. Return the key to the transmitter.

**Programming without a Recognized Transmitter (Keyless Access Vehicles Only):**

5. Place the new transmitter in the transmitter pocket/insert.
6. Press the ENGINE START/STOP button. When the transmitter is learned, the DIC will indicate readiness to program the next transmitter.
