    A traction battery at 80% means nothing if the 12V bus is dead. Here is how EV-safe towing actually works on scene.

    Electric vehicle prepared for flatbed transport
    Manufacturers differ on tow mode—tell dispatch your make, model year, and drivetrain layout.

    At a Glance

    • Best For

      EVs that will not power on, shift to neutral, or release electronic parking brakes after 12V failure.

    • Response

      Confirm immobilizer state → look up tow mode if possible → request flatbed if AWD → document.

    • Safety Note

      High voltage is usually isolated—still treat unknowns with respect and follow manufacturer guidance.

    • Tell Dispatch

      Make, model year, AWD/RWD/FWD, error messages, charge level if visible.

    Light-duty towing

    Dead 12V systems immobilize shifters and parking brakes—even when the main pack looks fine. Read our broad EV towing guide next, then return here for dispatch phrasing.

    Why the 12V Bus Still Runs the Show

    Contactors, computers, and parking brakes lean on the small battery. If you drive a Tesla, also bookmark Tesla-specific Bay Area towing for tow mode sequencing.

    If the touchscreen is black, assume tow mode cannot be enabled remotely—say that clearly.

    Flatbed Rationale for Modern EVs

    Many EVs are dual-motor AWD. When neutral cannot be verified, flatbed vs wheel-lift decisions tilt flatbed fast.

    For confirmed AWD without neutral, our AWD flatbed primer explains driveline stakes in plain language.

    Tow mode availability should be stated up front.

    Dispatch Script That Saves Time

    Say: make, year, AWD yes/no, wheels roll, steering unlocks, parking brake status. If you need pricing context, pair with insurance towing coverage.

    Peninsula fleet EV operators should pair this with our flatbed EV towing San Mateo checklist for pre-trip tow-mode verification.

    Send a photo of the dash if any warnings remain lit—operators plan around fault codes.

    Shop Handoff and High-Voltage Shops

    Not every shop accepts immobilized EVs—confirm destination before hook to avoid second tows.

    Keep charging fobs or phone keys available if the car suddenly wakes after a 12V swap attempt.

    Do This

    • Share complete vehicle details
    • Ask for itemized billing
    • Confirm destination before loading

    Avoid This

    • Accepting unclear pricing
    • Skipping method confirmation
    • Leaving without records
