Advanced Keyless Engine Start Function
• If a card key is with the driver when they enter the car, the engine can be started merely
by operating the start knob; without inserting a key in the ignition.
• When the start knob is pressed the keyless control module transmits an ID request
signal inside the vehicle, via the keyless antennas.
• When the card key receives the ID request signal, the indicator light on it flashes once,
and it transmits its ID to the keyless receiver, which passes the information on to the
keyless control module.
• The keyless control module verifies that the ID of the card key is valid, and unlocks the
start knob lock. At the same time, it illuminates the keyless indicator light (green) in the
instrument cluster.
NOTE: If the ID of the card cannot be identified (unregistered card key or flat card key
battery) the start knob lock will not be unlocked and the keyless indicator light will
blink red.
• The card key ID is verified a second time when the ignition is turned to the ON position
(indicator light on card key flashes once), and a permission signal is sent to the PCM to
allow the engine to be started (immobilizer function).
