If it cannot be turned off or turns off while driving, please go to the settings menu and select the vehicle model.* Standard/Rev (oil-only mode, auto power on/off)* Vehicles with automatic start-stop and hybrid power systems (primarily fuel-powered, battery-assisted, non-plug-in, and motor-driven)* Plug-in hybrid vehicle (primarily battery-powered with oil as a backup, featuring a rechargeable large battery)* If the vehicle is old or voltage control fails to shut down, set the sleep voltage to 13.2V. The vehicle will automatically shut down when it’s voltage drops below 13.2V.(u.s. cars can be used after 2008 and most other cars after 2008.)Package Included:1 x Head Up DisplayTime calibrationAfter connecting to the satellite, the device will automatically calibrate the time. The initial satellite search takes 3-5 minutes. Drive the vehicle to an open, unobstructed area. If colock still not correct, can set the clock in the menu.Please read carefully before placing an order:- After the product is powered on, it displays "No OBD2 signal detected."- Situation A, After the vehicle is powered on, the screen does not enter the normal operation interface, only displays voltage information, and automatically turns off after about 30 seconds.- Press the "OK" button to wake up the device and display it normally. Then press and hold the "OK" button for 2 seconds to enter the settings and select the vehicle type:①HEV/PHEV (primarily battery-powered with fuel as a supplement; the battery is relatively large and primarily charged)②HYB/COM (automatic start-stop and hybrid, primarily fuel-powered with battery as a supplement; cannot be charged, only powered by the electric motor)③STD/RPM(standard/rev, suitable for pure petrol vehicles; starts and stops with the engine)
