The fuel tank with a capacity of about 54 liters is located on the bottom in front of the rear axle. The current fuel level is indicated to the driver by an indicator device on the instrument panel. The fuel tank is ventilated by an exhaust ventilation system.
Harmful to the environment gasoline vapors, removed from the tank by ventilation, are captured by the adsorber and from there sent to the engine for subsequent combustion.
Fuel economy
Driving style largely determines fuel consumption.

Cleanliness and safety rules when working with the fuel system
When working with the fuel supply system, the following rules of cleanliness and safety precautions must be carefully followed:
- No open flames or sparks near the workplace!
- No smoking! The workplace must be equipped with a fire extinguisher!
- Ensure good ventilation of the work area. Fuel fumes are toxic.
- The fuel system is under pressure. Opening the system may cause fuel to escape. Collect any leaking fuel with a rag. Wear safety glasses when performing work.
- Before disconnecting pipelines, thoroughly clean the connecting joints and nearby surfaces.
- Place the removed parts on a clean lining and cover them with polyethylene film or paper. Do not use rags with lint for this!
- Carefully cover or seal any exposed or dismantled parts or components unless further work is to be carried out immediately.
- Remove spare parts from packaging immediately before installation. Install only clean parts.
- If possible, do not work with compressed air when the fuel system is open. If possible, do not move the vehicle.
- Do not use silicone-based sealant. Silicone particles are sucked in by the engine, but are not burned, and can damage the lambda probe.
