Checking the brake fluid level

Use only the specified brake fluid. (Refer to More Details.)
Never mix different types of fluid.

In the event the brake system requires frequent additions of fluid, the vehicle should be inspected by an authorized Kia dealer.

When changing and adding brake fluid, handle it carefully. Do not let it come in contact with your eyes. If brake fluid should come in contact with your eyes, immediately flush them with a large quantity of fresh tap water. Have your eyes examined by a doctor as soon as possible.

Proper fluid
Only use brake fluid in the brake system. Even small amounts of improper fluids can cause damage to the brake system.

Brake fluid
Do not allow brake fluid to contact the vehicle's body paint, as paint damage will result.
The brake fluid constantly absorbs moisture from the air. This lowers the boiling point of the brake fluid. If the boiling point is too low, vapor pockets may form in the brake system when the brakes are applied hard.
Brake fluid, which has been exposed to open air for an extended time should never be used as its quality cannot be guaranteed. It should be disposed of properly.

To maintain your vehicle’s best brake and ABS/ESC performance, use Kia genuine brake fluid as in the specification. (Classification: SAE J1704 DOT-4 LV, ISO4925 CLASS-6, FMVSS116 DOT-4)

Washer fluid

Do not use radiator coolant or antifreeze in the washer fluid reservoir. Radiator coolant can severely obscure visibility when sprayed on the windshield and may cause loss of vehicle control or damage to paint and body trim. Windshield Washer fluid agents contain some amounts of alcohol and can be flammable under certain circumstances. Do not allow sparks or flame to contact the washer fluid or the washer fluid reservoir. Damage to the vehicle or occupants could occur.
