Locks and Security
If all the closures (doors, trunk, hood) are closed, the park lamps will
flash once and the horn will chirp once when the on the remote entry
transmitter is pressed a second time within five seconds.
If any closure is not properly closed, the park lamps will not flash and
the horn will chirp twice.
The system will wait 20 seconds after one of the actions is performed
before allowing an alarm to go off. After the 20–second pre-arm phase,
the interior trim remote trunk release control and the power door unlock
control are disabled, in order to further protect your vehicle.

• Unlock the doors by using the remote entry transmitter.
