You can jumpstart a 2017 Mercedes CLA battery safely by following these steps: gather your equipment, connect the cables correctly, start the donor vehicle, and then start your CLA.
-
Gather your equipment: You will need a set of jumper cables and another vehicle with a fully charged battery. Ensure both vehicles are turned off during this process.
-
Connect the cables correctly:
– Attach one end of the red (positive) cable to the positive terminal of the dead battery.
– Connect the other end of the red cable to the positive terminal of the donor battery.
– Attach one end of the black (negative) cable to the negative terminal of the donor battery.
– Finally, connect the other end of the black cable to a metal ground point on the car with the dead battery. This reduces the risk of sparks near the battery. -
Start the donor vehicle: Turn on the donor vehicle’s engine. Allow it to run for a few minutes. This will send charge to the dead battery.
-
Start your CLA: After a few minutes, attempt to start your 2017 Mercedes CLA. If it does not start, wait another minute and try again.
-
Disconnect the cables in reverse order: After your CLA starts, carefully remove the cables in the reverse order of how you connected them. Start with the black cable from the ground point, then the black cable from the donor battery, followed by the red cable from the donor battery, and finally the red cable from your CLA.
-
Let the engine run: After jumpstarting, keep your CLA’s engine running for at least 20 minutes. This helps to recharge the battery.
Following these instructions can help prevent battery damage and ensure a safe jumpstart for your vehicle. Always consult your owner’s manual for specific instructions related to your car model.
