Universal Remote System
Vehicles with the Universal Remote
System will have these buttons
located in the headliner.
This system provides a way to
replace up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to have
another person assist with
programming the transmitter.
See Universal Remote System on
page 5 53.
