SECURITY AND LOCKS [ADVANCED KEYLESS SYSTEM]
KEYLESS ANTENNA CONSTRUCTION/OPERATION [ADVANCED KEYLESS SYSTEM]
• Consists of the antennas for request signal output (7 locations).
• Operated by the keyless control module, the keyless antennas send request signals to produce the reception
areas inside and outside the vehicle.
• The keyless antennas built-into the front doors can output signals to both inside or outside the vehicle, and
change the level of the radiowave (output to inside or outside the vehicle) according to operation conditions.
• The keyless control module locates the card key by determining the antenna which is receiving the signal the
strongest.
