Engine Oil and Filter
The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the vehicle is driven in severe conditions, more frequent oil and filter changes are required.
Drive Belts
Inspect all drive belts for evidence of cuts, cracks, excessive wear, or oil saturation. Replace them if necessary.
Check the drive belts periodically for proper tension and adjusted as necessary.
WARNING
Always turn off the engine before inspecting the drive belts.
Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses, and connections for leakage and damage. Have an authorized HYUNDAI dealer replace any damaged or leaking parts immediately.
Fuel Filter
The fuel filter is considered to be maintenance free but periodic inspection is recommended depending on the fuel quality. If there is fuel flow restriction, surging, loss of power, or hard starting, contact an authorized HYUNDAI dealer to have the fuel filter replaced immediately.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be inspected at intervals specified in the maintenance schedule. Your HYUNDAI dealer helps determine if replacement is needed.

The air cleaner filter should be replaced by an authorized HYUNDAI dealer.
Spark Plugs
Be sure to install new spark plugs with the correct heat range.
When installing new spark plugs, make sure the ignition coils are clean and free of any oil or debris. Clean and wipe off the bottom portion of the ignition coil to prevent any contamination with the spark plug during installation.
WARNING
Do not remove spark plugs from the vehicle when the engine is hot. You may damage the engine and may also risk burn injury.

Check the cooling system components such as radiator, coolant reservoir, hoses, and connections for leakage and damage. Replace any damaged parts.
Engine Coolant
The coolant should be changed at intervals specified in the maintenance schedule.
Automatic Transmission Fluid
The automatic transmission fluid level does not need to be checked under normal usage conditions.
If driven in severe operating conditions, have the automatic transmission fluid changed by an authorized HYUNDAI dealer according to the maintenance schedule under severe conditions.
Information
The color of a new automatic transmission fluid is red. As the vehicle is driven, the automatic transmission fluid begins to look darker.
This is normal and the automatic transmission fluid does not need to be replaced based on the color change.
NOTICE
Only use the automatic transmission fluid specified in the “Recommended Lubricants and Capacities” section in Chapter 10 to prevent transmission damage.
Brake Hoses and Lines
Visually check for proper installation, chafing, cracks, deterioration, and any leakage. Replace any deteriorated or damaged parts immediately.

Parking Brake
Inspect the parking brake system including the cables.
Brake Discs, Pads, Calipers, and Rotors
Check the pads, the disc, and the rotor for any excessive wear-out. Inspect calipers for any fluid leakage.
