Maintenance Procedures
Engine Oil Level
How to check engine oil level
To check engine oil level, park vehicle on
level ground and wait 15 minutes after
shutting off engine. After the engine is shut
off it will take at least 15 minutes for all the
engine oil to return to the sump.
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.
Make sure that the vehicle suspension is
sitting flat, both lengthwise and crosswise.
Check this carefully on a vehicle with air
suspension.
Engine coolant should be at or above the
operating temperature of 180°F (82°C).
This procedure should be followed as part
of routine maintenance checks.
1. Twist the dipstick handle to unlock it,
then pull the dipstick out of the
holder.
2. Wipe the dipstick clean with a lint-
free cloth.
3. Reinsert the dipstick into the holder.
4. Remove the dipstick from the holder
and check the oil level. The oil level
should always be between the two
marks on the dipstick.
5. Reinstall the dipstick and twist to lock
it in place.
