Refer to the engine manufacturer's
Engine Operation and Maintenance
Manual supplied with your vehicle for
information about draining and refilling
engine oil, engine crank case capacity,
engine oil type, and changing oil filters,
etc.
WARNING!
Hot engine oil can be dangerous.
You could be burned. Let the en-
gine oil cool down before changing
it. Failure to comply may result in
death, personal injury, equipment or
property damage.
Inspection of the Engine Oil Level
NOTE
It takes approximately 15 minutes
for all the oil to run into the sump
when the engine is ‘warm.’ If the
level is checked immediately after
switching off the engine, the dipstick
will show a low oil level.
1. Make sure that the vehicle frame
rail is standing on a flat and level
surface.
2. Make sure that the vehicle is
horizontal, both lengthwise and
crosswise. Check this carefully
on a vehicle with air suspension.
Note that the engine may be
inclined up to 4° depending on the
vehicle model and wheelbase.
3. Twist the dipstick handle to unlock
it, then pull the dipstick out of the
holder.
4. Wipe the dipstick clean with a
lint-free cloth.
5. Place the dipstick back into the
holder.
6. Pull the dipstick out again and
check the oil level. The oil level
should always be between the 2
marks on the dipstick.
