If your Tesla Model 3 is dead, or seems to be having troubles with the screen going out, you might just need to restart it.
The Tesla Model 3 has 3 reboot levels
Screen Reboot (GPU reboot)
If the screen is freezing, or if you are having other troubles with your Model 3, start with this reboot.
- Put the Tesla Model 3 in park
- Hold in both steering-wheel scroll buttons for a few seconds, and the screen will turn off
- Wait until the Tesla emblem shows on the screen
This procedure has helped some owners who had their Model 3 long-range RWD screen freeze
Here is a video of the screen reboot in the Model S, and the process is the same for the Model 3
Central Processor Reboot (CPU and GPU reboot)
- Put the Tesla Model 3 in park
- Push on the brake pedal and hold in both steering wheel scroll buttons until the screen turns off (takes a few seconds)
- After a while, the screen will show the Tesla emblem followed by a refreshed GPU and CPU
If you are having troubles with pairing your phone, turn if off, perform the reboot, and turn your smartphone back on while the CPU/GPU reboot is happening.
Here is a video of the Tesla Model 3 CPU reboot process
Hard Vehicle Reboot
First try the GPU, and then the CPU/GPU reboot above. If neither of those fixes your Tesla Model 3 problem, then try the hard reboot.
- Put the Tesla Model 3 in park
- Open the front hood and take the cover off of the 12-volt battery (located in front of the windshield)
- Use a 10mm wrench and unhook the cable from the visible terminal of the battery
- After a few seconds, reattach the 12-volt battery cable
The Tesla Model 3 hard reboot has fixed problems like not being able to recharge after connecting to a defective charging station.
Factory Reboot
[needed – is this the same as the hard vehicle reboot?]
