Kia Optima: Power Brakes
Your vehicle has power-assisted brakes that adjust automatically through normal usage.
In the event that the power-assisted brakes lose power because of a stalled engine or some other reason, you can still stop your vehicle by applying greater force to the brake pedal than you normally would. The stopping distance, however, will be longer. Refer to the scheduled maintenance guide for scheduled maintenance intervals.
When the engine is not running, the reserve brake power is partially depleted each time the brake pedal is applied. Do not pump the brake pedal when the power assist has been interrupted. Pump the brake pedal only when necessary to maintain steering control on slippery surfaces.
