# Service bulletin PS472R1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10109781
- Published by NHTSA: 2017\-08\-02
- Manufacturer's number: PS472R1
- Manufacturer's date: 2016\-11\-15
- NHTSA component: EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM

## NHTSA's summary

PITSTOP: HVAC VENTILATION LOGIC OPERATION \- Starting with 14MY Soul \(PS\) \(with the exception of PSEV\) and complete new models such as K900 \(KH\), Sedona \(YP\), Sorento \(UMa\), Optima \(JFa\), Sportage \(QL\), and 17MY Forte \(YD, YDm\), etc., equipped with a sunroof, a ventilation logic has been applied in order to prevent exhaust gases flowing into the vehicle due to the pressure difference \(inside vs outside\) that is generated when driving with the sunroof open. This logic allows the system to automatically switch from RECIRCULATION to FRESH mode when the sunroof is open.
