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.
*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.
M/T : Manual transmission
IVT : Intelligent Variable Transmission
DCT : Dual clutch transmission

CAUTION
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 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.

Hyundai Elantra AD (2016-2020) Owners Manual: Vehicle Stability Management (VSM)
The Vehicle Stability Management (VSM) is a function of the Electronic Stability
Control (ESC) system. It helps ensure the vehicle stays stable when accelerating
or braking suddenly on wet, slippery and rough roads where traction over the four
tires can suddenly become uneven.
