Brake Assistant System (BAS)
The BAS provides additional pressure when the brake pedal is momentarily and strongly depressed in a situation where sudden braking is required while driving.
The BAS reduces the time for ABS control to activate, and consequently reduces the braking distance, by providing additional pressure up to the point of ABS intervention.
BAS operation
-
When your Kia speed is more than 20 mph (30 km/h) and the ABS control is not activated.
-
When the brake pedal is fully depressed over a certain level.
-
When the friction of the road surface is above a certain level.
BAS operation off
-
Your Kia speed is below 6 mph (10 km/h).
-
The brake pedal is depressed over a certain road condition.
-
The friction of the road surface is below a certain level.
The system operates depending on driver's driving habit, vehicle speed, the degree to which the brake pedal is depressed and the road surface condition.
