What is wrong

On certain vehicles, a software problem could cause the rearview camera image not to appear on the central display. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear.

Why it matters

A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.

What the dealer will do

Mercedes-Benz will notify owners by mail and send a wireless over-the-air software update to each vehicle. If the update cannot be completed successfully, you will be notified to schedule an appointment to have the update performed by a dealer.
