*1 : Refer to the recommended SAE viscosity numbers on the next page.
*
2 : Requires grade engine oil. If a lower grade engine oil (mineral oil
including Semi-synthetic other than API SN plus) is used, then the engine oil and engine oil
filter must be replaced as indicated severe maintenance condition.
*
3 : Use only specified genuine Intelligent Variable Transmission fluid. The use of non-specified
fluid (even marked as compatible with genuine) could result in shift quality deterioration and
vibrations, eventually, the transmission failure.
*
4 :We recommend that you use the engine oils approved by HYUNDAI Motor India Ltd. We
recommend that you consult an authorized HYUNDAI dealer for details.
