Enlarge Shoji 30 Prius Early Model This product has multiple functions, such as automatic door mirror retraction. I installed it about a year ago, but I have removed it. Please see the photos for details. Installation was a simple coupler-on process, taking about 5 minutes. 1. Automatic Door Lock (Timing of door lock can be changed) The doors automatically lock when the shift lever is put into "D" or when the vehicle speed reaches approximately 15 km/h. ※ No re-lock function 2. Door Unlock (Timing of door unlock can be changed) The doors automatically unlock when the shift lever is put into "P" or when the engine is turned off! 3. Hazard lights flash when shifting into reverse (Function can be turned ON/OFF) 4. Hazard lights flash when the door is opened (Function can be turned ON/OFF) The hazard lights flash when the door is opened. 5. Emergency Door Unlock Activates during sudden deceleration of approximately 40 km/h or more. (e.g., from 60 km/h to below 20 km/h) Unlocks the doors to prepare for emergencies and avoid being trapped during an emergency escape. ※ Please note that it may not work during sudden braking. ※ This function cannot be turned OFF. 6. Power Window Function (Function can be turned ON/OFF) When the power window function is ON, you can close all open windows using the smart key lock button or the door handle lock button. Depending on your vehicle's package, the confirmation hazard lights may not flash. After changing the power window settings, the mirror retraction function will not work only once. In that case, open the door once and press the LOCK key again, and it will work normally afterwards. 7. Door Mirror Retraction Settings (Function can be turned ON/OFF and the timing of mirror return can be set) The mirrors automatically retract when you press the smart key lock button or the door handle lock button.
