Main Menu Table Of Contents Keyless Access System Beeper and Message Keyless Remote Not Detected The displayed message goes away when you bring the remote back inside the vehicle. If the engine is running and you take the remote out of the vehicle, it will continue to run. Once the power mode is changed to VEHICLE OFF (LOCK), the engine will not restart until you bring back a remote into the vehicle. The engine does not start if you push the engine start/stop button when the remote is outside the vehicle. Check where the remote is. Make sure that you carry the remote with you when you operate the engine start/stop button. Even when the remote is inside the vehicle, the beeper may sound when the location of the remote is not detected due to surrounding conditions. It is not a failure. Make sure that you carry the remote with you. Instruments and Controls If you take the keyless access remote out of the vehicle and close the door with the power mode ON, the inside and outside beepers sound and a ''KEYLESS REMOTE NOT DETECTED'' message will be displayed on the multi-information display.
