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.
