# Service bulletin CBR\-2452 202503

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.

## NHTSA's summary

If the vehicle door is open and the truck is in neutral, a popup message may appear on the Driver Information Display \(DID\) instructing the operator to shift into neutral. If this message appears while the vehicle is already in neutral, the Instrument Cluster \(IC\)requires a software update.
