You Can Honk Your Tesla Horn To Save Dashcam Clips – Here’s How

First, a formatted USB drive must be inserted into one of the vehicle’s USB ports. Tesla recommends using the USB port located inside the glovebox, if available, to keep the flash drive hidden and unobtrusive. Teslas manufactured in 2020 or later actually come with a pre-formatted USB drive. But for owners that need to format their own flash drives, the vehicle can format the drive for you by pressing Controls, then Safety, then Format USB Drive. Of course, the flash drive can also be formatted the old-fashioned way — on a computer.

Next, the dashcam must be enabled by pressing Controls, then Safety, then Dashcam. Under Dashcam, you will press a button labeled On Honk and that’s it. Note that On Honk can be enabled independently or in conjunction with other Dashcam modes like Auto and Manual. 

Now when the horn is pressed, the previous 10 minutes of dash cam footage is saved to your flash drive. The recorded footage can be viewed either on the Tesla’s touchscreen when the vehicle is in park or the flash drive can be removed from the vehicle and the footage can be viewed on a computer. Hopefully, you’ll never have an incident that necessitates Save on Honk, but it’s nice to know it’s there just in case.
