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.

NOTICE

• When the engine overheats from low engine coolant, suddenly adding engine coolant may cause cracks in the engine. To prevent damage, add engine coolant slowly in small quantities.
• Do not drive with no engine coolant.
  It may cause water pump failure and engine seizure, etc.

Checking the Engine 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 F and the L marks on the side of the coolant reservoir when the engine is cool. If the coolant level is low, add enough distilled (deionized) water to bring the level to the F mark, but do not overfill. If frequent additions are required, see an authorized HYUNDAI dealer for a cooling system inspection.

WARNING

1. Check if the radiator cap label is straight In front.
2.  Make sure that the tiny protrusions inside the radiator cap should be securely interlocked.

Recommended engine coolant

• When adding coolant, use only distilled (deionized) water for your vehicle and never mix hard water in the coolant filled at the factory.
• An improper coolant mixture can result in severe malfunction or engine damage.
• The engine in your vehicle has aluminum engine parts and must be protected by an ethylene-glycol with phosphate-based 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. It is suitable to use for most temperature ranges of – 31°F and higher.

WARNING
The electric motor for the cooling fan may continue to operate or start-up when the engine is not running and can cause serious injury. Keep hands, clothing, and tools away from the rotating fan blades of the cooling fan. The electric motor for the cooling fan is controlled by engine coolant temperature, refrigerant pressure, and vehicle speed. As the engine coolant temperature decreases, the electric motor will automatically shut off. This is a normal condition.

Changing Engine Coolant
Have the coolant changed by an authorized HYUNDAI dealer according to the Maintenance Schedule at the beginning of this chapter.

WARNING
Do not use engine coolant or antifreeze in the washer fluid reservoir.
Engine coolant can severely obscure visibility when sprayed on the windshield and may cause loss of vehicle control resulting in an accident.
Engine coolant may also cause damage to the paint and body trim.

NOTICE
To prevent damage to engine parts, put a thick towel around the radiator cap before refilling the coolant to prevent the coolant from overflowing into engine parts, such as the alternator.

BRAKE/CLUTCH FLUID

Checking the Brake/Clutch Fluid Level

Check the fluid level in the reservoir periodically. The fluid level should be between MAX and 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 fluid to the MAX level. The level will fall with accumulated mileage. This is a normal condition associated with the wear of the brake linings.
If the fluid level is excessively low, have the system be checked by an authorized HYUNDAI dealer.

Information
Use only the specified brake/clutch fluid. Refer to “Recommended lubricants and capacities” in chapter 2.

Information
Before removing the brake/clutch filler cap, read the warning on the cap.

Information
Clean the filler cap before removing. Use only DOT4 brake/clutch fluid from a sealed container.

WARNING
Do not let brake fluid enter into your eyes. If brake fluid gets in your eyes, flush your eyes with clean water for at least 15 minutes and get immediate medical attention.

NOTICE

• Do not allow brake/clutch fluid to contact the vehicle’s body paint, as it will result in paint damage.
• NEVER use brake fluid that has been exposed to open air for an extended time, as its quality cannot be guaranteed. It should be disposed of properly.
• Don’t put in the wrong type of fluid.
  A few drops of mineral-based oil, such as engine oil in your brake system can damage system parts.
• To maintain the best braking performance and ABS/ESC performance, have you use genuine brake/clutch fluid that conforms to specifications?
  (Standard : SAE J1704 DOT-4 LV, ISO4925 CLASS-6 and FMVSS 116 DOT-4)

Washer Fluid

Checking the Washer Fluid Level
Check the fluid level in the washer fluid reservoir and add fluid if necessary. Plain water may be used if washer fluid is not available. However, use washer solvent with antifreeze characteristics in cold climates to prevent freezing.

WARNING
To prevent serious injury or death, take the following safety precautions when using washer fluid:

• Do not use engine coolant or antifreeze in the washer fluid reservoir.
  Engine coolant can severely obscure visibility when sprayed on the windshield and may cause loss of vehicle control resulting in an accident or damage to paint and body trim.
• Do not allow sparks or flames 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 skin. Washer fluid is harmful to humans and animals.
• Keep washer fluid away from children and animals.

PARKING BRAKE

Checking the Parking Brake

Check the stroke of the parking brake by counting the number of “clicks’’ heard while fully applying it from the released position. Also, the parking brake alone should securely hold the vehicle on a fairly steep grade. If the stroke is more or less than specified, have the system be serviced by an authorized HYUNDAI dealer.
Stroke : 5~8 “clicks’’ at a force of 44 lbs (20 kg, 196 N)
