Engine oil and engine oil filter
The engine oil and engine oil filter should be changed at the intervals specified in the maintenance schedule. When operating the car in difficult conditions, replacement must be done more often.
Drive belts
Check all drive belts for cuts, cracks, excessive wear and oil contamination and replace if necessary. The tension of the drive belts should be checked periodically and adjusted if necessary.
Fuel filter element
A clogged fuel filter can cause a limited speed at which the vehicle can be driven, failure of the emission control system, and poor engine starting. If an excessive amount of foreign matter accumulates in the fuel tank, the fuel filter may need to be replaced more frequently. After installing a new filter, let the engine run for a few minutes and check for leaks at the connections. The fuel filter must be installed by an authorized Hyundai dealer.
Fuel lines, flexible hoses and connections
Check fuel lines, fuel hoses and connections for leaks and damage. Contact your authorized Hyundai dealer immediately to replace any damaged or leaking hoses.
Attention. Only for vehicles with diesel engine. Do not service the fuel injection system while the engine is running or within 30 seconds of shutting it down. The high pressure pump, fuel manifold, injectors and high pressure lines are a source of high pressure even after the engine is turned off. A jet of fuel from a leak can cause serious injury if it comes into contact with a person's body. People with pacemakers should not come closer than 30 cm to the ECU or electrical wiring in the engine compartment when the engine is running, because the high currents in the common rail system generate strong magnetic fields.
Ventilation hose and fuel filler cap
The condition of the fuel tank vent hose and fuel filler cap should be checked at the intervals specified in the maintenance schedule. Check that the fuel tank vent hose or fuel filler cap has been properly replaced.
Vacuum and crankcase ventilation hoses (in the presence of)
Check the surface of flexible hoses for signs of thermal and/or mechanical damage. Signals of deterioration in their quality are the rigidity and brittleness of the rubber coating, cracks, tears, cuts, abrasive damage and excessive swelling. Particular attention should be paid to those surfaces of flexible hoses that are located near strong heat sources such as the exhaust manifold. Check flexible hoses along their entire length to make sure they are not in contact with any heat source, sharp edges, or moving parts that could cause thermal damage or mechanical wear. Check all flexible hose connections (clamps, fittings, etc.), to make sure they are securely fastened and there are no leaks. If there is any sign of wear, aging or damage, the flexible hoses must be replaced immediately.
Air filter
When replacing, it is recommended to use an original air filter supplied by Hyundai.
Spark plug (for petrol engine)
Verify that the thermal characteristics of the installed spark plugs meet the specified requirements.
Valve clearance (for petrol engine)
Check for excessive valve noise and/or engine vibration and adjust if necessary. This operation must be performed by an authorized Hyundai dealer.
Cooling system
Check engine cooling system components such as radiator, expansion tank, flexible hoses and connections for leaks and damage. Replace all damaged parts.
Coolant
The coolant must be replaced at the intervals specified in the maintenance schedule.
Manual transmission oil (in the presence of)
Check the oil level in the manual transmission according to the maintenance schedule.
Oil for automatic transmission (in the presence of)
The condition of the oil in an automatic transmission does not need to be checked if the vehicle is operated under normal conditions. However, if the vehicle is operated under severe conditions, the transmission oil must be changed by an authorized Hyundai dealer in accordance with the maintenance schedule at the beginning of this section.
Note.
- Automatic transmission oil usually has a reddish tint.
- As the vehicle is used, the oil in the automatic transmission becomes darker in appearance. This is normal, so do not worry and change the oil if it changes color.
Attention. The use of a transmission fluid that does not meet the requirements can lead to malfunctions of the transmission and its failure. Use only recommended brands of automatic transmission fluid.
Pipelines and flexible hoses of the brake system
By visual inspection, check for proper installation, no abrasions, cracks, wear and any leaks. Replace any damaged or worn parts immediately.
Brake fluid
Check the brake fluid level in the expansion tank of the brake system. The level must be between the marks «MIN» And «MAX» on the side of the tank. Use only DOT 3 or DOT 4 brake fluid.
Parking brake
Check the parking brake system, including the parking brake lever (or pedal) and drive cables.
Disc brakes, brake pads, calipers and discs
Check brake pads for excessive wear, discs for runout and wear, calipers for brake fluid leakage.
Suspension mounting bolts
Check the suspension mounts for loose bolts or damage. Tighten the screw connections to the specified tightening torque.
Crankcase, gear and steering gear boots/lower arm ball joint
Stop the vehicle, turn off the engine and check for excessive steering wheel play. Check the steering gear for deformation and damage. Check the condition of the protective boots and ball joints for wear, cracks or damage. Replace all damaged parts.
Power steering pump, belt and hoses
Check the condition of the power steering pump and hoses for leaks and damage. Replace any damaged or leaking parts immediately. Check Power Steering Belt (or drive belt) for cuts, cracks, excessive wear, oiliness and related tension. Adjust or replace it if necessary.
Wheel drive shafts and covers
Check the wheel drive shafts, boots and clamps for cracks, wear and damage. Replace any damaged parts and repack assemblies with grease if necessary.
Air Conditioning Refrigerant/ Air Conditioning Compressor (in the presence of)
Check air conditioner lines and connections for leaks and damage.
