GENERAL INFORMATION

WARNING

Brake fluid must never come into contact with fluids containing mineral oils (oil, gas, cleaning solutions). Mineral oils damage brake system seals. Brake fluid is poisonous and must not be extracted by mouth using a hose under any circumstances. In addition, it must not come into contact with paint due to is corrosive effects. Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore always be stored in air-tight containers. Observe waste disposal regulations!

Note. If the air filter insert is heavily soiled or soaked, dirt particles or moisture can reach the mass airflow sensor -G70- and cause an incorrect airflow reading. This causes lack of performance because a lower injection amount is calculated. Always use an original air filter insert. Use a lubricant (silicone-free) when installing intake hose. Check drain hose in bottom side of air filter or dirt and adhesion (clean, if necessary). Secure all hose connections with hose clamps that match current standard production. Clean air filter housing (upper and lower parts) of salt residue, dirt or leaves (clean with vacuum, if necessary). Check mass airflow sensor and intake hose (clean air side) for salt residue, dirt and leaves. Check the intake canal up to the filter insert for dirt. When installing air filter insert, ensure it is centered in mount on bottom of air filter. Carefully and gently place upper part of air filter on lower part. When doing so, ensure upper part of air filter is not crooked on air filter insert. Pay attention to the seal lip on the air filter insert (air leak). Finally, screw upper part of air filter onto lower part.

WARNING

Oil extraction not permitted with various engine types! See maintenance table.

Note. Perform oil change at operating temperature.
