*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my 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.

3If the API service SM engine oil is not available in your country, you are able to use API service SL.

Recommended SAE viscosity
number
Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (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.Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing 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.
CAUTION
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.

*1For better fuel economy, it is recommended to use the engine oil
of a viscosity grade 5W-30 (API SM / ILSAC GF-4 / ACEA A5 or
above). However, if the engine oil is not available in your country,
select the proper engine oil using the engine oil viscosity chart.

2For 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.

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 car.The engine number is stamped on the
engine block as shown in the drawing.The refrigerant label provides infor-
mation such as refrigerant type and
amount.
The label is located on the underside
of the hood.
