CAUTION
Always be sure to clean the areaaround any filler plug, drain plug, ordipstick before checking or drain-ing any lubricant. This is especiallyimportant in dusty or sandy areasand when the vehicle is used onunpaved roads. Cleaning the plugand dipstick areas will prevent dirt and grit from entering the engineand other mechanisms that couldbe damaged.

*1For better fuel economy, it is recommended to use the engine oil of a viscosi-
ty grade SAE 5W-20 (API SM / ILSAC GF-4). However, if the engine oil is not
available in your country, select the proper engine oil using the engine oil vis-
cosity chart.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather oper-
ating (starting and oil flow). Lower viscosity engine oils can provide better fuel econ-
omy and cold weather performance, however, higher viscosity engine oils are
required for satisfactory lubrication in hot weather. Using oils of any viscosity other
than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operat-
ed in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.
