What's wrong, in plain English

In certain Mercedes-Benz vehicles with the Audio 20 head unit and automatic child seat recognition, the passenger air bag status may not display correctly on the dashboard. If the display incorrectly shows the passenger air bag as 'on' when it is actually off, a front seat passenger may not realize the air bag will not inflate in a crash. Not knowing this increases their risk of injury if a crash happens.

1. Check your VIN at nhtsa.gov/recalls. 2. Contact Mercedes-Benz USA customer service at 1-800-367-6372 to schedule a dealer visit. 3. Dealers will update the audio head unit software for free.

Where do I find my VIN, and what do I tell the dealer?
