X Add the amount of oil required. Fill carefully to the maximum mark on the oil dipstick. i The difference in quantity between the MIN mark and the MAX mark on the dipstick is (depending on the engine) approximately 1.6 to 2.1 US qt. (1.5 to 2 l). ! Do not add too much oil. If the oil level is above the MAX mark on the dipstick, too much oil has been added. This can lead to damage to the engine or the catalytic converter. Have excess oil siphoned off. Further information on engine oil (Y page 361). X Replace cap : on the filler neck and tighten clockwise. Ensure that the cap locks into place securely.

Rdo not remove the pressure cap on the coolant reservoir if the coolant temperature is above 158 ‡ (70 †). Allow the engine to cool down before removing the cap. The coolant reservoir contains hot fluid and is under pressure. Rusing a rag, slowly turn the cap approximately 1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure. Rdo not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. Z Maintenance and care
