Engine oil 
Checking oil level 
1.Park the vehicle on a level surface 
2.Switch the engine off after it has 
reached normal operating temperature 
3.After approx. 5 minutes, pull the dip-
stick 4 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 
5.The oil should extend to between the 
two marks on the dipstick. 
As is the case with fuel economy, the rate 
at which the engine uses oil is strongly 
influenced by driving style and operating 
conditions.
The oil quantity between the two marks on 
the dipstick 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.
