Changing Engine Oil and Filter

CAUTION: Touching hot surfaces can burn skin. The engine, components, and fluids will be hot if the engine has been running. Allow the engine to cool before servicing or working near the engine and components.

IMPORTANT: Change the oil more often if the vehicle is used in extreme conditions:

• Extremely dusty conditions.
• Frequent slow or low-speed operation.
• Frequent short trips.
