Inspection of the Engine Oil<br />
Level<br />
NOTE: It takes approximately<br />
15 minutes for all the oil to run<br />
into the sump when the engine<br />
is ‘warm.’ If the level is checked<br />
immediately after switching off<br />
the engine, the dipstick will<br />
show a low oil level.<br />
1. Make sure that the vehicle frame<br />
rail is standing on a flat and level<br />
surface.<br />
2. Make sure that the vehicle is<br />
horizontal, both lengthwise and<br />
crosswise. Check this carefully<br />
on a vehicle with air suspension.<br />
Note that the engine may be<br />
inclined up to 4° depending on the<br />
vehicle model and wheelbase.<br />
3. Twist the dipstick handle to unlock<br />
it, then pull the dipstick out of the<br />
holder.<br />
4. Wipe the dipstick clean with a<br />
lint-free cloth.<br />
5. Place the dipstick back into the<br />
holder.<br />
6. Pull the dipstick out again and<br />
check the oil level. The oil level<br />
should always be between the 2<br />
marks on the dipstick.<br />
7. Reinstall the dipstick and twist to<br />
lock it in place.
