Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
1. Park the vehicle on a level surface with the
engine warm, i.e. after an uninterrupted
drive of at least 6 miles/10 km.
2. Switch off the engine.
3. After approx. 5 minutes, pull the dipstick 3
out and wipe it off with a clean lint-free
cloth, paper towel, or similar material.
4. Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two
marks on the dipstick.
The oil quantity between the centers of the two
marks on the dipstick, refer to arrows, is approx.
1.6 US quarts/1.5 liters.
Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine. <
