Power Mode Reminder

If you open the driver’s door when the power mode is set to ACCESSORY, a warning beep sounds

Keyless Remote Reminder

Warning buzzers may sound from inside and/or outside the vehicle to remind you that the keyless access remote is out of the vehicle. If the buzzer continues even after the remote is put back inside, place it to be within its operational range.

When the power mode is in ON

If the keyless access remote is taken out of the vehicle, and all doors are closed, a warning buzzer sounds from both inside and outside the vehicle. A warning message on the multiinformation display notifies the driver inside that the remote is outside of the vehicle.

When the power mode is in ACCESSORY

If the keyless access remote is taken out of the vehicle, and all doors are closed, a warning buzzer sounds from outside the vehicle.

When the keyless remote is within the system’s operational range, and the driver’s door is closed, the warning function cancels.

If the keyless remote is taken out of the vehicle after the engine has been started, you can no longer change the ENGINE START/STOP button mode or restart the engine. Always make sure if the remote is in your vehicle when you operate the ENGINE START/STOP button.

Removing the keyless remote from the vehicle through a window does not activate the warning buzzer.

Do not put the keyless remote on the dashboard or in the glove box. It may cause the warning buzzer to go off. Under some other conditions that can prevent the vehicle from locating the remote, the warning buzzer may also go off even if the remote is within the system’s operational range.
