Trim / Codes
Nissan's SR trim has generally served as a sport-styled variant on models such as the Sentra, Altima, and Versa, with model year changes typically limited to minor feature updates, wheel designs, or infotainment revisions. Common service considerations include routine oil changes, CVT transmission fluid inspections on models with continuously variable transmissions, and standard brake and tire maintenance. Some SR trims equipped with turbocharged engines may require premium fuel and more frequent spark plug replacement. Checking NHTSA records for recalls and technical service bulletins specific to the vehicle's model year is recommended.
