Service bulletin A901340 2029781-

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.

The driver information system (DIS) display screen is completely blank or appears to be all white The condition is intermittent and the DIS can function normally when the key is cycled off and back on.
