RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.
*
3API SL/ILSAC GF-3/ACEA A3 oil can be used if the recommended oil is not available.

Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant. This is especially
important in dusty or sandy areas
and when the vehicle is used on
unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operation (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory 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 operated in before the next oil
change. Proceed to select the recom-
mended oil viscosity from the chart.

*1. For better fuel economy, it is recommended to use the engine oil of
a viscosity 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 viscosity chart.

The tires supplied on your new vehi-
cle are chosen to provide the best
performance for normal driving.
The tire label located on the driver's
side center pillar gives the tire pres-
sures recommended for your vehicle.
The engine number is stamped on
