Programming without a Recognized Transmitter (Keyless Access Vehicles Only)

If there are no currently recognized transmitters available, follow this
procedure to program up to eight transmitters. This feature is not
available in Canada. This procedure will take approximately 30 minutes
to complete. The vehicle must be off and all of the transmitters you wish
to program must be with you.

1. Remove the key lock cylinder cap. See Door Locks on
page 2-10. Then insert the vehicle key into the key lock
cylinder on the driver door handle and turn the key,
counterclockwise, to the unlock position five times within
10 seconds.
The Driver Information Center (DIC) displays REMOTE LEARN
PENDING, PLEASE WAIT.
2. Wait for 10 minutes until the DIC displays PRESS ENGINE
START BUTTON TO LEARN and then press the ENGINE
START/STOP button. The DIC displays will again show REMOTE LEARN
PENDING, PLEASE WAIT.
3. Repeat Step 2 two additional times. After the third time, all
previously known transmitters will no longer work with the
vehicle. Remaining transmitters can be relearned during the next
steps.The DIC display should now show READY FOR REMOTE # 1.
4. Place the new transmitter into the transmitter pocket. The
transmitter pocket is inside the center console storage area.
5. Press the ENGINE START/ STOP button. When the
transmitter is learned the DIC will show that it is ready to
program the next transmitter.
6. Remove the transmitter from the transmitter pocket and press K.
To program additional transmitters, repeat Steps 4–6.
When all additional transmitters are programmed, press and hold
the ENGINE START/STOP button for 12 seconds to exit
programming mode.
