Answer Back System
The answer back system is a device to find
the location of your vehicle and to inform
you that the immobilizer function of the
Honda SMART Key system is activated.
When you press the answer back/alarm
button on the Honda SMART Key with the
ignition switch is in the
position and the anti-theft alarm system is
set, the turn signals light, the ignition switch
ring lights, and the buzzer rings, informing
you of your vehicle's location and activation
of the immobilizer function.
The ignition switch ring will light for about 1
minute.
The answer back system uses low-intensity
radio waves. It may affect medical equipment
such as a cardiac pacemaker.
