supervisory board in 2021, succeeding Manfred Bischoff. Ask Dr. Z campaign On 30 June 2006 Chrysler Group announced the Employee Pricing Plus program, which featured Dieter Zetsche as Dr. Z (Doctor Zee), the DaimlerChrysler spokesman for a series of US and Canadian television commercials, also animated in cartoon format on the company's Ask Dr. Z website, which began on 1 July. The "Ask Dr. Z" campaign included television, radio, print, online, in-dealership and customer relationship marketing media components and aggressive marketing tactics (mobile billboards, aerial banners, street teams), as well as targeting the NASCAR fan community. In the "Ask Dr. Z" ad campaign he provides answers to customers' questions and exits by saying Auf Wiedersehen (German for "goodbye" or "see you again"). The ad campaign emphasized the consumer benefits of combined American and German engineering and design. One commercial included Zetsche riding in a Jeep Liberty while crossing a pile of logs; another showed him in the trunk of a Dodge Caravan minivan, heading a soccer ball; and the last showed him at the wheel of a Chrysler Pacifica during a crash test, then emerging from the wreckage unscathed. The campaign was criticized for having the wrong guy for doing funny ads. CNW Marketing Research poll showed most people thought Dr. Z was a fictional character, did not notice the employee discount offer in the ads and radio commercial listeners had difficulty understanding his German accent. DaimlerChrysler hurriedly withdrew the Dr. Z campaign three months later, due to a significant loss in market share. However, some of the Dr. Z ads can still be seen on Canadian television. In later broadcasts, the tagline in Dr. Z TV ads was changed to "See the best in German and North American design in your Dodge and Chrysler dealer." As a response to shrinking sales, its employee pricing plus program was extended through the end of August and three new TV ads, which did not feature Dr. Z, were added to the August campaign. TUI AG In February 2018, before the announcement of his departure from Daimler, in the annual general meeting held by tourism company TUI AG, Zetsche was elected as a member of the supervisory board.
