Service bulletin 09-37

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.

See Table 1. • For certain 114SD vehicles, replace the metal safety screen with a pleated safety element. See Table 2. • For 108SD, 114SD, M2 106, and M2 112 vehicles with air ducts specified in Table 3, install an additional seal. These modifications will improve the sealing quality of the air cleaner and help prevent dust from entering the engine. Detailed information is provided below.
