4.2 CHECKING THE ENGINE
OIL LEVEL
For oil capacities, see the Specifications section. For engine oil
recommendations, see the Engine Oil Recommendations section.
To check the engine oil level, proceed as follows (Figures 4.2, 4.3
and 4.4):
1. Move the AUTO/OFF/ MANUAL switch to the OFF position.
2. Remove the dipstick and wipe it dry with a clean cloth.
3. Completely insert the dipstick; then, remove it again. The oil
level should be at the dipstick "Full" mark. If necessary, add
oil to the "Full" mark only. DO NOT FILL ABOVE THE "FULL"
MARK.
Never operate the engine with the oil level
below the "Add" mark on the dipstick. Doing
this could damage the engine.
4. Install the dipstick.
5. Reset the AUTO/OFF/MANUAL switch to its original position.
