2026 Genesis G90 Alarm System / Security User Guide
This guide delves into the advanced 2026 Genesis G90 alarm system and security features intended to improve protection. Understand how sophisticated sensors, smart key technology, and anti-theft features provide peace of mind.
Theft Alarm System
This system helps protect your vehicle and valuables. The horn sounds and the hazard warning lights blinks continuously if any of the following occur:
- A door is opened without using the smart key.
- The liftgate is opened without using the smart key.
- The engine hood is opened.
The alarm continues for 30 seconds, then the system resets. To turn off the alarm, unlock the doors with the smart key. The Theft Alarm System automatically sets 30 seconds after you lock the doors and the liftgate. For the system to activate, you must lock the doors and the liftgate from outside the vehicle with the smart key or by touching the touch sensor on the outside of the door handle with the smart key in your possession. The hazard warning lights blink and the chime sounds once to indicate the system is armed. Once the security system is set, opening any door, liftgate, or hood without using the smart key causes the alarm to activate. The Theft Alarm System is not set if the hood, liftgate, or door is not fully closed. If the system is not set, check the hood, liftgate, or doors are fully closed. Do not attempt to modify this system or add other devices to it.
Information
- Do not lock the doors until all passengers have left the vehicle. If a door is opened after the system is armed, the alarm is activated.
- If the vehicle is not disarmed with the smart key, open the doors by using the mechanical key and start the engine by directly pressing the Engine Start/Stop button with the smart key.
- If the system is disarmed by unlocking the vehicle, but a door or liftgate is not opened within 30 seconds, the doors are relocked and the system is rearmed automatically.
- It is not recommended to install any secondary aftermarket theft-alarm systems into the vehicle factory electrical system.
Information
Vehicles equipped with a theft alarm system have a label attached to the vehicle with the following words:
- WARNING
- SECURITY SYSTEM
REAR OCCUPANT ALERT (ROA) (IF EQUIPPED)
Rear Occupant Alert is provided to help prevent the driver from leaving the vehicle with the rear passenger left in the vehicle.
System Setting
To use Advanced Rear Occupant Alert, enable it from the Settings menu in the infotainment system. Select:
- Setup > Vehicle > Convenience > Rear Occupant Alert
Information
The infotainment system may change after software updates. For more information, refer to the manual provided in the infotainment system and the quick reference guide.
System Operation
When you turn off the engine and open the driver’s door after opening and closing the rear door, the “Check rear seats for passengers and belongings” warning message appears on the cluster display.
Information
To turn the warning message off, press the OK button.
WARNING
Always check the rear seats before you leave the vehicle.
The Rear Occupant Alert system does not actually detect the presence of objects or occupants in the rear seat but just informs you to check the rear seat by using the record of the rear door opening and closing.
Information
The record of the rear door opening and closing resets only when the driver turns the vehicle off and locks the vehicle door. Even if the rear door has not been reopened, an alert may occur if the door record is not reset. For example, if the driver opens the door and exits the vehicle again without locking the door after the Rear Occupant Alert operates, the alert may occur again.
ADVANCED REAR OCCUPANT ALERT (ROA) (IF EQUIPPED)
Advanced Rear Occupant Alert is provided to help prevent the driver from leaving the vehicle with the rear passenger left in the vehicle.
The system is designed to help detect an infant and child’s presence.
System Setting
To use Advanced Rear Occupant Alert, enable it from the Settings menu in the infotainment system. Select:
- Setup > Vehicle > Convenience > Rear Occupant Alert
Information
The infotainment system may change after software updates. For more information, refer to the manual provided in the infotainment system and the quick reference guide.
System Operation
- First alert
When you turn off the vehicle and open the driver’s door after opening and closing the rear door, the
‘Check rear seat for passengers and belongings’ warning message appears on the cluster. - Second alert
After the first alert, the second alert operates when it detects an infant or child’s presence after the driver’s door is closed and all the doors are locked. The horn will sound for about 25 seconds. Also, a text message is sent to members of Genesis Connected Services (if equipped). If the system continues to detect a movement, the alert operates up to 8 times.
Unlock the doors with the smart key to stop the alert. - The system detects movement in the vehicle for 10 minutes after the door is locked.
Information
- The second alert is available for vehicles equipped with the ROA sensor.
- The second alert is activated only after the prior activation of the first alert.
- If you do not want to use Advanced Rear Occupant Alert, press the OK button on the steering wheel when the first alert is displayed on the cluster. Doing so deactivates the second alert one time.
- Cluster
- Steering wheel
- If the vehicle is started remotely (if equipped with Remote Start), inside movement detection stops.
Advanced Rear Occupant Alert Precautions
- Make sure that all the windows are closed. If the window is open, the alert may operate by the sensor detecting an unintended movement (for example, wind or bugs).
- The system is intended to detect the movement of infants sitting in the rear seats. But a movement detected in the driver or passenger seats may cause a false alert.
- If the rear door is opened, and an infant or child is in the rear seat, then the alert may operate after the vehicle is locked.
- An alert can occur if there is an impactor strong movement on the vehicle.
- If boxes or objects are stacked in the vehicle, the system may not detect passengers.
- The alert may operate if the vehicle is pushed, shaken, being washed, or in an environment with noise/vibration after the vehicle is locked.
- The alert may operate when there are metallic or liquid objects in the vehicle.
WARNING
Even if your vehicle is equipped with Advanced Rear Occupant Alert, always check the rear seats before you leave the vehicle.
Advanced Rear Occupant Alert may not operate when:
- Movement does not continue for a certain period of time.
- A child is not seated in a child restraint system.
- The detection may be weak if the signal is obstructed by the vehicle seat or Child Restraining System (for example, child is restrained in the forward facing position).
- The rear passenger is a child over 6 years.
- The rear passenger is covered with a fabric containing metallic substance such as a blanket.
- An object in the vehicle blocks the sensor.
- The sensor is contaminated by foreign material.
