son, make sure that people and
objects are clear of the garage door
or other devices to prevent injury or
other potential harm.
 It is recommended that a new bat-
tery be placed in the remote control
transmitter for more accurate pro-
gramming.
 Garage door opener motors manu-
factured after 1995 may be
equipped with rolling code protec-
tion. If this is the case, you may need
a stepladder or other sturdy, safe
device to reach the “Learn” or
“Smart” button on the garage door
opener motor. ■

cle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is much higher
than the specified level.
• If wheels not equipped with tire pressure
warning valves and transmitter are used.
• If the ID code on the tire pressure warn-
