🚨 2013 Mercedes-Benz SL400 R231: Emergency Neutral
The R231 SL400 uses a center console-mounted electronic selector lever (7G-TRONIC PLUS) with fully electronic shift-by-wire system and electronic parking brake.
🧰 Drafted with AI under the editorial review of Chris Hackleman & Jeff Moore — details like the exact override location may vary by trim; verify visually before prying anything.
⚠️ Chock the wheels first — neutral means the car can roll. Set the parking brake while you work, never stand downhill of the vehicle, and try a 12-volt jump before any override: power fixes most stuck-in-park problems instantly.
The procedure
- Ensure the vehicle is on a level surface (electronic parking brake may not release without power)
- If any battery power exists, turn the ignition to position 2 (ON) or press START without the brake to get accessory mode
- Locate the shift lock override: on the R231, look for a small circular or rectangular cap on the right front side of the shifter base
- Remove the cap using a small flathead screwdriver or trim tool
- Insert the emergency key or screwdriver into the override slot and press down firmly
- While holding the override, move the selector to Neutral position
- If completely dead, you must provide 12V auxiliary power to the jump-start terminal under the hood—the shift-by-wire system requires electrical power to function

With zero electrical power
The R231 has a fully electronic transmission selector and electronic parking brake (EPB). With zero 12V power, the EPB will remain engaged and cannot be released mechanically. You must provide auxiliary power via the jump-start terminal in the engine compartment. Connect a jumper pack or external battery, turn on ignition, then use the override to shift to Neutral. The electronic steering lock also requires power. Without power restoration, flatbed transport is the only option.
