IMPORTANT EMISSION 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 Mercedes-Benz vehicles is extending the warranty coverage on the
ignition coil 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:

e The ignition coil might not operate and meet specifications as intended due to a fault in the winding process of the ignition
coil. This may cause reduction in the coil’s performance, and lead to combustion misfires on the affected cylinder. This may
also cause an increase in exhaust emissions and result in the illumination of the check engine Malfunction Indicator Lamp
(‘MIL’).
