Hyundai Accent (HC) (2017 - 2022) Service Manual: Light bulbs
Consult an authorized HYUNDAI dealer to replace most vehicle light bulbs. It is difficult to replace many Hyundai Accent light bulbs because other parts of the vehicle must be removed before you can get to the bulb. This is especially true when removing the headlamp assembly to access certain bulb(s), or when LED components are integrated into the lamp housing.Hyundai Accent (HC) (2017 - 2022) Service Manual: Explanation of scheduled maintenance items
Engine Oil and Filter The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the Hyundai Accent is being driven in severe conditions, more frequent oil and filter changes are required to protect the engine from accelerated wear and sludge buildup. Drive Belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary.
