Seats: Description and Operation
OPERATIONVoltage is present at the power lumbar switches at all times from circuit breaker 12.
Each lumbar seat has its own switch to change the cushion shape by operating an air pump. Operating the switch in one direction runs the pump to inflate the bladder; operating the switch in the opposite direction opens a bleeder valve and deflates the bladder.
Each power lumbar motor is protected by a self-resetting circuit breaker.
