DESCRIPTION AND OPERATION

GARAGE DOOR OPENER DESCRIPTION AND OPERATION

The garage door opener is located in the overhead console. The valet switch provides battery voltage to the
garage door opener. If battery voltage is lost due to a condition such as a dead battery, the garage door opener
unit relies on the non-servicable internal power backup supply. The unit is programmed using the customer's
hand-held transmitters for the garage doors, electric entrance gates, or lighting and security systems.

The garage door opener is rolling code capable. Rolling code is a system that allows the code that the customers
receiver receives from the garage door opener to change every time the garage door opener is used within
operating range of the receiver. When the receiver and the garage door opener are initially programmed
together, a code is established, a new code is created for every new transmission. The software in the receiver
recognizes the garage door opener and accepts the new code.

The garage door opener is compatible with most, but not all types and brands of transmitters. If a problem
should occur with a compatibility conflict with a transmitter, call HomeLink(tm) at 1-800-355-3515.

The garage door opener is a transmitter operating between 288-399 MHz. The power and range of the
transmitter is limited to comply with laws governing the generation of radio frequency interference (RFI). The

separate transmitter. Operation consists of simply pressing a button to activate the corresponding transmitter.

Battery voltage is provided to the garage door opener from the IGN SEN fuse in the IP fuse block. The garage
