Detailed description: Battery

The terminal voltage of the battery is 12V and the capacity is dependent on the engine variant. The battery delivers current to the starter motor for starting the engine and supplies other power consumers with current while the engine is not running. The positive battery terminal is connected to the starter motor and to the main fuse box in the engine bay and its negative terminal is connected to the body and the engine.

The battery is located on the left-hand side of the engine bay. On some variance, it is contained in a battery cover to reduce heating. An air duct takes in air via the car's grille. The air from the air duct passes through the battery cover and consequently cools down the battery.

The battery electrolyte cannot be topped up. The battery electrolyte level is indicated by an indicator point on the top of the battery. If the indicator is dark, the level is OK. On low level the indicator is light and the battery should be changed.
