You need to get the car hooked up to a diagnostic scanner to see what the fault codes are indicating. Looking at the types of faults, it seems as though one problem has caused all the warning lights to turn on. It's usually the smart city braking control system or the tyre pressure indicator system that causes this issue. The SCBS uses a foward facing camera, which can cause failure if it gets dirty. The tyre pressure warning can be caused by a failed tyre pressure monitor valve or one of your tyres has low pressure. All the warning lights are on because all of these systems affect each other if failed.
