Opening and Closing the Window

To open:

Closing:
Pull the power window switch up to the first detent position (5). Release the switch when you want the window to stop.
Automatic Window Up/Down
Briefly press or pull up the power window switch to the second detent position (6) to fully lower or raise the window even after the switch is released. To stop the window at a desired position during operation, pull up or press down and release the switch.
Resetting the Power Windows
If the power windows do not operate normally, the automatic power window system must be reset as follows:
1. Turn the engine start/stop button to the ON position.
2. Close the window and continue pulling up the power window switch for at least one second.
If the power windows do not operate properly after resetting, have the system inspected by an authorized HYUNDAI dealer.
WARNING
The automatic reverse function is not activated when the power window system is reset. Before closing the windows, make sure body parts or other objects are clear of the window to avoid injury or vehicle damage.
Automatic Reverse

If the window detects any obstruction during automatic closing, it will stop and lower approximately 12 inches (30 cm) so that the object can be cleared.
If the window detects resistance while the power window switch is continuously pulled up, the window will stop moving up and then lower approximately 1 inch (2.5 cm).
If the power window switch is again continuously pulled up within 5 seconds after the window has lowered by the automatic reverse function, the automatic reverse function will not operate.
Information
The automatic reverse function is active only when the "Auto Up" function is used by fully pulling the switch to the second detent.
WARNING
Before closing, make sure that body parts or other objects are clear of the window to avoid injury or damage to the vehicle.
Objects less than 0.16 inch (4 mm) in diameter caught between the window glass and the upper window channel may not be detected by the automatic reverse function, and the window will not stop or reverse.
NOTICE
Do not install any accessories on the windows. The automatic reverse function may not operate.
