Any water-amplifier pump shall make sound at work. These sounds are increasing until the rudder is at the helm. The operation of Kia Cerato 2 does not recommend that the rudder be held for at least 5 seconds. It is also prohibited to increase engine speed if the rudder is in the extreme position. This is related to the increase in pressure to the system, which may result in damage to the patrons and pump.
The hissing and low hum at the steering wheel, which are ampliated in the extreme positions, usually do not indicate a malfunction and are the result of the peculiarities of the steering system of the steering wheel in Kea Serato 2.
