NOTICE●
In order to prevent clutch slippage
(since the engine oil also lubricates
the clutch), do not mix any chemical
additives with oil. Do not use oils with
a diesel specification of “CD” or oils
of a higher quality than specified. In
addition, do not use oils labeled “EN-
ERGY CONSERVING II” or higher.
●
Make sure that no foreign material en-
ters the crankcase.
12. Start the engine, and then let it idle for several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
13. Turn the engine off, wait at least 10 min- utes, and then check the oil level and cor-
rect it if necessary.
14. Install the right rear panel by installing the bolts and the quick fastener screws. 15. Lower the cargo bed.1XP7C_EE.book Page 14 Monday, June 9, 2014 5:17 PM

2. Check the coolant level in the coolant
reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture. TIPThe coolant should be between the minimum
and maximum level marks.
