🚨 1997 Mercedes-Benz S350 Turbodiesel W140: Emergency Neutral

The W140 uses a traditional column-mounted automatic transmission shifter with mechanical linkage and an electronic shift interlock.

🧰 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

  1. Apply parking brake firmly and chock wheels.
  2. Turn ignition key to position II (ignition on) if battery has any charge remaining.
  3. Depress brake pedal fully.
  4. If shifter releases, move to neutral; if not, proceed to override.
  5. Locate the shift lock override slot on the lower left side of the steering column shroud, near where the shifter stalk enters the column.
  6. Remove the small rectangular cover cap (approximately 15mm x 10mm) by prying gently with a flat-blade screwdriver.
  7. Insert a small flat-blade screwdriver or the key blade into the override slot and press firmly.
  8. While holding the override pressed, move the shifter to neutral position.
  9. Remove screwdriver and replace cover cap.

With zero electrical power
With completely dead battery and ignition off, the mechanical override must be used. The shift lock is spring-loaded and the override mechanically releases it without electrical power. Ensure you maintain firm pressure on the override while shifting.
