Engine Oil Guide
Checking the engine oil level
Engine oil is used for lubricating, cooling, and operating various hydraulic components in the engine. Engine oil consumption while driving is normal, and it is necessary to check and refill the engine oil regularly. Also, check and refill the oil level within the recommended maintenance schedule to prevent deterioration of oil performance.
Check the engine oil following the below procedure.
- Follow all of the oil manufacturer’s precautions.
- Make sure the vehicle is on the level ground in P (Park) with the parking brake applied.
- Turn on the engine and warm the engine up until the coolant temperature reaches a constant normal temperature.
- Turn off the engine, remove the oil filler cap and pull the dipstick out. Wait for 15 minutes for the oil to return to the oil pan.
- Wipe the dipstick clean and re-insert it fully.
- Pull the dipstick out again and check the level. The level should be between F (Full) and L (Low).
- If the oil level is below L, add enough oil to bring the level to F.
Use only the specified engine oil (Refer to the “Recommended Lubricants and Capacities” section in Chapter 10).
NOTICE
To prevent damage to your engine:
- Do not spill engine oil when adding or changing engine oil. Wipe off spilled oil immediately.
- The engine oil consumption may increase while you break in a new vehicle, and it should stabilize after driving 4,000 miles (6,000 km).
- The engine oil consumption can be affected by driving habits, climate conditions, traffic conditions, oil quality, etc. Therefore, it is recommended that you inspect the engine oil level regularly and refill it if necessary.
Checking the engine oil and filter
- The lubrication, rust prevention, cooling, and cleaning effect of the engine oil will gradually degrade during its use. Have the engine oil and filter be changed by an authorized HYUNDAI dealer according to the Oil Life Management System function or the Maintenance Schedule at the beginning of this chapter.
- To keep the engine in optimal condition, use the recommended engine oil and filter. If the recommended engine oil and filter are not used, replace it according to the maintenance schedule under severe usage conditions.
- The purpose of the maintenance schedule for engine oil replacement is to prevent oil deterioration and it is irrelevant to oil consumption. Check and refill engine oil regularly.
Information
When the oil pressure is low due to insufficient engine oil, the Engine Oil Pressure
warning light illuminates. In addition, the enhanced engine protection system, which limits the engine’s power is activated and the Malfunction Indicator Lamp
illuminates. After sufficient engine oil is added, the Engine Oil Pressure warning light turns off and the engine power is no longer limited.
However, for gasoline 2.5 GDI engine, when the engine oil pressure is restored, the warning light and the enhanced engine protection system turns off after the engine is restarted.
WARNING
Allow the engine to cool before replacing the oil.
NOTICE
Never add any additives to the engine oil. Engine oil additives can change the properties of engine oil and may cause serious engine failure.
Engine Coolant
The high-pressure cooling system has a reservoir filled with year-round antifreeze coolant.
The reservoir is filled at the factory. Check the antifreeze protection and coolant level at least once a year, at the beginning of the winter season and before traveling to a colder climate.
Checking the coolant level
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen or deteriorated hoses.
The coolant level should be filled between the MAX and the MIN marks on the side of the coolant reservoir when the engine is cool.
If the coolant level is low, add enough distilled (deionized) water mixed with antifreeze to bring the level to the MAX mark. If frequent additions are required, contact an authorized HYUNDAI dealer.
WARNING
Never remove the radiator cap or the drain plug while the engine and radiator are hot. Hot coolant and steam may blow out under pressure, causing serious injury.
Turn the engine off and wait until the engine cools down. Use extreme care when removing the radiator cap. Wrap a thick towel around it, and turn it counterclockwise slowly to the first stop. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, press down on the cap, using a thick towel, and continue turning counterclockwise to remove it.
Information
The coolant level is influenced by the engine temperature. Before checking or refilling the coolant, turn off the engine and allow the engine to cool.
WARNING
Keep hands, clothing, and tools away from the rotating fan blades of the cooling fan.
Always turn off the vehicle unless the vehicle has to be inspected with the engine on. The cooling fan may operate automatically if the negative (-) battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly closed after refilling the coolant. Otherwise, the engine could be overheated while driving.
- Check if the coolant cap label is straight in front.
- Make sure that the tiny protrusions inside the coolant cap is securely interlocked.
Recommended coolant
- When adding coolant, use only deionized water, distilled water or soft water for your vehicle and never mix hard water in the coolant filled at the factory.
- An incorrect coolant mixture can result in severe malfunction or engine damage.
- The engine in your vehicle has aluminium engine parts and must be protected by a phosphate-based ethylene glycol coolant to prevent corrosion and freezing.
- Do not use alcohol or methanol coolant or mix them with the specified coolant.
- Do not use a solution that contains more than 60 % antifreeze or less than 35 % antifreeze, which would reduce the effectiveness of the solution.
For mixing percentage, refer to the following table:
| Ambient Temperature | Mixture Percentage (volume) | |
| Antifreeze | Water | |
| 5 °F (-15 °C) | 35 | 65 |
| -13 °F (-25 °C) | 40 | 60 |
| -31 °F (-35 °C) | 50 | 50 |
| -49 °F (-45 °C) | 60 | 40 |
Information If in doubt about the mix ratio, a 50 % water and 50 % antifreeze mix is the easiest to mix together as it will be the same quantity of each.
Changing coolant
Have the coolant changed by an authorized HYUNDAI dealer according to the Maintenance Schedule.
NOTICE
To prevent damage to engine parts, put a thick towel around the engine coolant cap before refilling the coolant to prevent the coolant from overflowing into engine parts, such as the alternator.
BRAKE FLUID
Checking the Brake Fluid Level
Check the fluid level in the reservoir periodically. The fluid level must be between the MAX and the MIN marks on the side of the reservoir.
Before removing the reservoir cap and adding brake fluid, clean the area around the reservoir cap thoroughly to prevent brake fluid contamination.
If the level is low, add the specified brake fluid to the MAX level. If the fluid level is excessively low or frequent additions are required, have the brake system inspected by an authorized HYUNDAI dealer.
WARNING
If brake fluid comes in contact with your eyes, flush your eyes with clean water for at least 15 minutes and get immediate medical attention.
NOTICE
- Do not allow brake fluid to contact the vehicle’s body paint, because paint damage may occur.
- Never use brake fluid that has been exposed to open air for an extended time and dispose of it properly.
- Do not use the wrong type of brake fluid. A few drops of mineral based oil such as engine oil in your brake system may damage the brake system parts.
Information
Use only the brake fluid specified in the “Recommended Lubricants and Capacities” section in Chapter 10.
WASHER FLUID
Checking the Washer Fluid Level
Check the fluid level in the washer fluid reservoir and add fluid if necessary. Plain water can be used during summer months if washer fluid is not available. However, use washer fluid with antifreeze in cold climates to prevent freezing.
WARNING
To prevent serious injury or death:
- Do not use engine coolant or antifreeze in the washer fluid reservoir. Engine coolant can severely limit your visibility when sprayed on the windshield and may cause loss of vehicle control resulting in a collision.
- Do not allow sparks or flame to contact the washer fluid or the washer fluid reservoir. Washer fluid may contain alcohol and can be flammable.
- Do not drink washer fluid and avoid contact with the skin.
