Engine Maintenance
• Refer to the engine manufacturer's Engine Operation
and Maintenance Manual supplied with your vehicle for
information about draining and refilling engine oil, engine
crankcase capacity, engine oil type, and changing oil filters,
etc.
WARNING! Hot engine oil can be dangerous. You
could be seriously burned. Let the engine oil
cool down before changing it.
• Drain the oil into a container designed for this purpose.
• When draining the oil, remove the plug with the proper
size wrench and keep as far away as possible. Always
keep your forearm parallel to the ground to help prevent
hot oil from running down your arm.
• The oil filler cap must be secured to avoid oil spill causing
a potential fire hazard.
Oil Level Check
• To check the engine oil level, park the vehicle on level
ground and wait 5 minutes after shutting the engine OFF.
This allows time for the oil to drain to the oil pan.
• Remove the dipstick and wipe it off with a clean, lint-free
rag.
