# Service bulletin SB72\-40

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

On Cascadia vehicles built from November 25, 2013, the drain holes at the bottom of the cab doors were enlarged to improve drainage during the e\-coat process in the manufacturing plant. The larger holes allow more cold air to flow through the doors, most noticeably in extreme cold conditions.
