Dealers will inspect the batteries, including fluid levels. Some batteries may be replaced if necessary, on a case by case basis. In addition to the battery inspection, the addition of labels in the vehicle owner's manual and engine compartment will be included to conspicuously remind owners as well as dealer and service personnel of the need to perform battery maintenance. Owner notification began February 20, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Mercedes-Benz at 1-800-367-6372.
