Can’t start your Mercedes-Benz GLA-Class due to a dead battery? Learn how to fix the problem by jump-starting your Mercedes-Benz dead battery. This guide provides instructions on jump-starting a Mercedes-Benz GLA-Class with a dead battery.
What you will need
- 12V Jump Starter
- Jumper Cables – Requires a running car
- Remove the metal blade/key from your Mercedes-Benz key fob. A release button in the key fob will pop out the metal key. Use the metal key to unlock the driver’s door.
- Open the hood by pulling the hood release lever under the dashboard.
- Press the yellow release under the hood towards the passenger side and raise the hood.
- Locate the terminals in the engine bay designed to jump-start your Mercedes-Benz. Pull/open the RED plastic cover with the + symbol to locate the positive port. The terminals are on the driver’s side.
- Connect the red (positive) jumper cable to the positive terminal.
- Connect the black (negative) jumper cable to the ground terminal on the vehicle frame.
- Make sure that the red cable (positive) is connected to the positive terminal and the black cable (negative) is connected to the negative terminal if another vehicle is used to jump-start the vehicle.
- Get inside the car and start the engine. If the car does not start away, let the battery charge for at least ten to fifteen minutes and then start it again.
Once the engine starts, drive or let it idle for at least twenty minutes to charge the battery. If the battery is completely discharged or has a bad cell, the battery may not have enough power to restart the engine.
When you start the engine, the ABS and other lights may be on. As long as there are no other issues, these reset automatically after driving for a few minutes. If the ABS, airbag, or traction control light doesn’t reset, follow this guide to read Mercedes-Benz fault codes.
