Important safety notes G
WARNING
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide (CO),
and inhaling it can cause unconsciousness
and possible death. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and possible death.
You can use the HomeLink ®
garage door
opener integrated into the rear-view mirror to
operate up to three different gate/garage
door opener systems. 274
