Maintenance
(Continued)
Do not modify or tamper with
any part of the engine or
emission control system. Allinspections and adjustments
must be made by an author-
ized HYUNDAI dealer.
Avoid driving with an extreme-
ly low fuel level. Running out of fuel could
cause the engine to misfire,
damaging the catalytic con-
verter.

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.

Refer to “Fuel requirements” in the Introduction chapter.
*1
: Refer to the recommended SAE viscosity numbers on the next page.
* 2
: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy 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.
* 3
: If the ACEA A5/B5 engine oil is not available in your country, you are able to use ACEA A3/B3, A3/B4.

Specifications & Consumer information
Recommended SAE viscosity
number
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
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy 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
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.
