KIA Niro: Explanation of scheduled maintenance items (Kia NIRO Hybrid)
Engine oil and filter
The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the vehicle is being driven in severe conditions, more frequent oil and filter changes are required.
Hybrid Starter & Generator (HSG) belt
Inspect all hybrid starter & generator belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Hybrid starter & generator belts should be checked periodically for proper tension and adjusted as necessary.
When you are inspecting the belt, place the ignition switch in the LOCK/OFF or ACC position.
Kia gasoline vehicles are equipped a lifetime fuel filter that integrated with the fuel tank. Regular maintenance or replacement is not needed but depends on fuel quality. If there are some important safety matters like fuel flow restriction, surging, loss of power, hard starting problem etc, fuel filter inspection or replace is needed.
Have the fuel filter inspected or replaced by a professional workshop. Kia recommends to visit an authorized Kia dealer/ service partner.
Fuel lines, fuel hoses and connections
Check the fuel lines, fuel hoses and connections for leakage and damage. Have the fuel lines, fuel hoses and connections replaced by a professional workshop.

Make sure to install new spark plugs of the correct heat range.
When assembling parts, be sure to wipe the inside and outside of the boot bottom of the ignition coil and the insulator of the spark plug with a soft cloth to prevent contamination of the spark plug insulator.
Do not disconnect and inspect spark plugs when the engine is hot. You may burn yourself.
Check the cooling system components, such as the radiator, coolant reservoir, hoses and connections for leakage and damage. Replace any damaged parts.
The coolant should be changed at the intervals specified in the maintenance schedule.
Dual clutch transmission (DCT) fluid
Inspect the dual clutch transmission fluid according to the maintenance schedule.
Brake hoses and lines
Visually check for proper installation, chafing, cracks, deterioration and any leakage. Replace any deteriorated or damaged parts immediately.
Check the brake fluid level in the brake fluid reservoir. The level should be between "MIN" and "MAX" marks on the side of the reservoir. Use only hydraulic brake fluid conforming to DOT 4 specification.
Brake discs, pads and calipers
Check the pads for excessive wear, discs for run out and wear, and calipers for fluid leakage.
For more information on checking the pads or lining wear limit, we recommend to refer to the Kia web site.
Suspension mounting bolts
Check the suspension connections for looseness or damage. Retighten to the specified torque.
Steering gear box, linkage & boots/lower arm ball joint
With the vehicle stopped and engine off, check for excessive free-play in the steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for deterioration, cracks, or damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and clamps for cracks, deterioration, or damage.
Replace any damaged parts and, if necessary, repack the grease
Air conditioning refrigerant
Check the air conditioning lines and connections for leakage and damage.
Checking fluid levels
When checking engine oil, engine coolant, brake fluid, and washer fluid, always be sure to clean the area around any filler plug, drain plug, or dipstick before checking or draining any lubricant or fluid. 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.
