Hyundai Equus: Trunk Lid Control Button

When the trunk lid control button is ON (depressed), the power trunk can be controlled with the power trunk main control button, power trunk open, close button, and the smart key.
When this trunk lid control button is OFF (not depressed), the power trunk can be controlled using the mechanical key of the smart key only.
Even though the trunk lid control button is OFF (not depressed), the trunk will still be propelled upward by mechanical force if the trunk is manually opened more than 10 degrees beyond the fully closed position. In addition, if the trunk is manually closed to the secondary latch position, the trunk will be electrically moved to the fully latched position.
WARNING
CAUTION
Close the trunk, and keep the trunk lid control button in the OFF (not depressed) position before washing the vehicle in an automatic car wash.
Emergency Trunk Safety Release

Your vehicle is equipped with an Emergency Trunk Safety Release lever located inside the trunk. When someone is inadvertently locked in the trunk, the trunk can be opened by moving the lever in the direction of the arrow and pushing the trunk open.
