MAP LIGHTS (if so equipped)
To turn the map lights on, press the lenses.
To turn them off, press the lenses of the
lights again.
CAUTION
Do not use for extended periods of time
with the engine stopped. This could re-
sult in a discharged battery.The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:
∙ Will operate most Radio Frequency de- vices such as garage doors, gates,
home and office lighting, entry door
locks and security systems.
∙ Is powered by your vehicle’s battery. No separate batteries are required. If the
vehicle’s battery is discharged or is dis-
connected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, refer to “Programming
HomeLink®” in this section.
WARNING
∙ Do not use the HomeLink® Universal Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse does not meet cur-
rent federal safety standards. Using a
garage door opener without these
features increases the risk of serious
injury or death.
∙ During the programming procedure your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage door,
gate, etc., that you are programming.
∙ Your vehicle’s engine should be turned off while programming the
HomeLink® Universal Transceiver.
