| For safety reasons, fuse No. 28 must be removed from the fuse holder before opening the fuel system. Otherwise, the fuel pump could be activated by the driver's door contact switch. |
WARNING | Fuel system is under pressure! Wear eye protection and gloves to avoid injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection. |

| t
| Before beginning work, place an extraction hose close to sender opening in fuel tank to extract escaping fuel fumes and switch on exhaust extraction system. If no exhaust gas extraction system is available, a radial fan with a displacement greater than 15 m3/h can be used providing that motor is not in air flow. |
