J Replacing lost transmitters
If you lose a transmitter or want to purchase addi-
tional transmitters (up to four can be programmed),
you should re-program all of your transmitters for
security reasons. It is recommended that you have
your dealer program all of your transmitters into your
system.
B Programming the transmitters
The keyless entry system is equipped with a special
code learning feature that allows you to program
new transmitter codes into the system or to delete
old ones. The system can learn up to four unique
transmitter codes. The four transmitter codes may
be the same or different.
To enter the programming mode:
1. Press “UNLOCK/DISARM” button to disarm the
security system. (If your vehicle is equipped with the
optional security system.)
