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 transfer case/rear differential is submerged, visit an authorized HYUNDAI genuine products to replace the
differential oil.
*4 To maintain the best braking performance and ABS/ESC performance, use genuine brake fluid that conform to
specifications.
*5 Requires <API SN PLUS (or above) Full synthetic> grade engine oil. If a lower grade engine oil (mineral oil
including semi-synthetic) is used, then the engine oil and engine oil filter must be replaced as indicated severe
maintenance condition.
Recommended SAE viscosity number
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 operating
(engine start and engine oil flow ability). Typically, 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. For these engines, only
use 0W-20 weight engine oil.
Never add any additives to the engine oil. Engine oil additives can change the properties
of engine oil and may cause serious engine failure.
WL_OilAPIMark
An engine oil displaying this American Petroleum Institute (API) Certification Mark
conforms to the International Lubricant Specification Advisory Committee (ILSAC). It is
recommended to only use engine oils that uphold this API Certification Mark.
