In the case of a dead battery, you can jump-start your Dacia Duster (2015) using jumper cables and another vehicle. Park the donor vehicle close to yours, ensuring both engines are off. Connect the red (positive) jumper cable clamp to the positive terminal of your Duster's battery and then to the donor vehicle's positive terminal. Attach the black (negative) clamp to the donor vehicle's negative terminal. Now, connect the remaining black clamp to an unpainted metal surface on your Duster, away from the battery. Start the donor vehicle and wait a few minutes, then attempt to start your Duster.
