Hyundai Genesis Sunroof Motor Initialization & Emergency Handle Procedure
Service procedure page describing sunroof motor initialization and emergency handle operation with adjustment figures.
This service procedure page covers sunroof adjustment and emergency operation. The first section, 'How To Initialize,' explains the sunroof motor initialization: verify the glass is installed and height adjustment is finished, then push and hold the up switch until the slide moves forward 5.0 mm (approximately 15 seconds), release, turn OFF, then push and hold the UP switch continuously — if initialization is successful, the sunroof should fully slide open and close once. Two illustrations show the slide before and after movement (reference SBHBD8201L). The second section lists when to initialize the motor: after first operation following manufacture, when the initial value is erased or damaged due to a short power electric discharge, or after using the manual handle. The third section, 'Operating The Sunroof Emergency Handle,' describes manually closing or opening the sunroof if it cannot be closed electronically due to motor or controller malfunction: remove the overhead console, push the emergency handle into the hexagonal drive (A) of the sunroof motor firmly enough to disengage the motor clutch, turn clockwise to close, and wiggle the handle when removing to re-engage the clutch. A 5mm hex socket with a 'Speeder'-type handle may substitute. A caution warns against using power tools to operate the sunroof, as component damage may occur.

Frequently asked questions
- How do I initialize the sunroof motor?
- Check that the glass is installed and height adjustment is finished. Push and hold the up switch until the slide moves forward 5.0 mm (about 15 seconds), then release. Turn OFF the switch, then push and hold the UP switch continuously — if initialization is successful, the sunroof should fully slide open and close once. When it is closed completely, turn OFF the UP switch to complete initialization.
- When does the sunroof motor need to be initialized?
- 1) On first operation of the vehicle after manufacture, 2) when the initial value is erased or damaged because of a short power electric discharge during operation, and 3) after using the manual handle.
- How do I close the sunroof manually if the motor fails?
- Remove the overhead console, push the emergency handle up into the hexagonal drive (A) of the sunroof motor hard enough to disengage the motor clutch, then carefully turn the handle clockwise to close the sunroof. After closing, wiggle the handle back and forth as you remove it so the motor clutch reengages.
- Can I use a tool other than the emergency handle to operate the sunroof manually?
- Yes — a 5mm hex socket may be used in place of the emergency handle, with a 'Speeder' type handle. However, the document cautions: do not use power tools to operate the sunroof, as damage to the components may occur.
