FORD 2013 Flex v.1 - Manual (Page 68)

Remote Starting the Engine
Note: Each button press must be done within three seconds of each
other. The vehicle will not remote start if this sequence is not followed
and the horn will not chirp.
The label on your transmitter details
the starting procedure. To remote
start the engine:
1. Press the lock button to lock all the doors.
2. Press the remote start button twice. The exterior lamps will flash
twice.
The horn will chirp if the system fails to start (unless quiet start is on).
Quiet start will run the blower fan at a slower speed to reduce noise. It
can be switched on or off. Refer to the Information Displays chapter.
Note: If the vehicle has been remote started and is equipped with an
integrated keyhead transmitter, you must turn the ignition on before
driving the vehicle. If equipped with an intelligent access transmitter, you
must press the START/STOP button on the instrument panel once while
applying the brake pedal before driving the vehicle.
The power windows will be inhibited during the remote start and the
radio will not turn on automatically.
The parking lamps will remain on and the engine will run for 5, 10, or
15 minutes, depending on the setting. Refer to the Information Displays
chapter to select the duration of the remote start system.
Extending the Engine Run Time
Repeat Steps 1 and 2 with the engine still running to extend the run
time for another remote start duration. If you programmed the duration
to last 10 minutes, the second 10 minutes will begin after what is left of
the first activation time. For example, if the vehicle had been running
from the first remote start for five minutes, the engine will continue to
run now for a total of 15 minutes. You can only extend the remote start
once.
Wait at least five seconds before remote starting after an engine
shutdown. Only two remote starts are allowed.
