IMPORTANT EMISSIONS EXTENDED WARRANTY INFORMATION
In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our
customers, Mercedes-Benz AG (“MBAG”), the manufacturer of the Mercedes-Benz vehicles is extending the warranty coverage on
the secondary air injection system combination valve in certain Model Year (“MY”) vehicles listed below from the original New
Vehicle Limited Warranty of 4 years/50,000 miles to 15 years / 150,000 miles (whichever occurs first) due to the following
condition:
•

The secondary air injection system combination valve may not close completely under certain climate conditions due to
condensation in the exhaust system. An open combination valve could lead to an activation of a Malfunction Indicator
Lamp (‘MIL’), which could cause the vehicle to fail a state smog inspection.
Model Model Years
Smart 2016 – 2017

Sales Designation
Smart fortwo coupe, Smart fortwo cabriolet
