Additional information:
- Always refer to your vehicle's owner's manual for specific instructions and precautions regarding battery replacement.
- When disconnecting or reconnecting battery terminals, ensure you touch only the terminals themselves and avoid contact with any other metallic surfaces to prevent sparks or short circuits.
- Some Mercedes ML350 models may have a battery sensor or a cable attached to the battery that should be reconnected after battery replacement. Consult your vehicle's manual for specific instructions.
- It's recommended to replace the negative battery terminal first and the positive terminal last when disconnecting the battery and reconnect the positive terminal first and negative terminal last when reconnecting to minimize the risk of sparks and short circuits.
