As mentioned above the lights other than the SES typically point to the steering angle sensor. This also happens when ever you remove power from the vehicle. To correct that you can turn the wheel in park full left to the stops and then right to the stops. If that doesn't work, there is a calibration routine in ISTA. If neither one of those work, you'll need to identify the fault with a DTC and probably replace the SAS. As for the SES, you'll need a readout to see what fault is causing that as there are several possibilities.
