DS 3 2016-2026 Owners Manual

If the vehicle's battery is flat, the engine can be started using a backup battery (either external or from another vehicle) and jump leads or using a battery booster.

Never start the engine by connecting a battery charger.

Never use a 24 V or higher battery booster.

Check beforehand that the backup battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery. The two vehicles must not be in contact with each other.

Switch off all electricity-consuming equipment on both vehicles (audio system, wipers, lighting, etc.).
