Mercedes-Benz vehicles use different parking brake systems depending on the model and production year. Identifying which system your vehicle is equipped with is essential to release the parking brake safely and correctly, especially in situations such as towing, a dead battery, or parking brake warning messages on the dashboard.
1. Electronic Parking Brake (EPB) – Most Modern Models
Common on C-Class, E-Class, S-Class, GLC, GLE, and newer AMG models.
Normal release procedure
Start the engine or switch the ignition to the ON position. Press and hold the brake pedal firmly. Pull down or press the electronic parking brake (EPB) switch, depending on the model. The red parking brake warning light on the instrument cluster should turn off, confirming successful release.
Automatic release
On many Mercedes-Benz models, the parking brake will release automatically when you shift into Drive (D) or Reverse (R) while pressing the accelerator with the seat belt fastened.
Important notes
If the battery voltage is low, the EPB may fail to disengage. Warning messages such as “Parking Brake Malfunction” or stored fault codes can also prevent release and typically require a diagnostic tool to reset or repair.
2. Foot-Operated Parking Brake – Older Mercedes Models
Common on older E-Class (W211), ML-Class, GL-Class, and some CLS models.
Normal release procedure
Locate the foot-operated parking brake pedal on the far left side of the driver’s footwell. Pull the parking brake release handle, usually located under the lower dashboard or near the left kick panel. The pedal should return to its original position, and the brake warning light should turn off.
If it does not release
The parking brake cable may be seized, worn, or stretched, particularly in cold or humid climates. In this case, manual inspection and mechanical adjustment or replacement may be required.
3. Manual Handbrake – Older or Entry-Level Models
Found on older A-Class, B-Class, and classic Mercedes-Benz models.
Release steps
Press the brake pedal for safety. Lift the handbrake lever slightly, press the release button, and then lower the lever completely to disengage the parking brake.
Releasing the Parking Brake with a Dead Battery
When the vehicle battery is fully discharged, electronic parking brakes cannot be released using normal procedures.
Recommended solutions
Jump-start the vehicle or connect an external power source to restore sufficient voltage. Use a diagnostic tool that supports Mercedes-Benz EPB service or emergency release mode. In towing or emergency situations, professional roadside assistance is strongly recommended to prevent damage to the brake system or EPB actuators.
