The campaign, from agency Ogilvy & Mather, Chicago, is tagged "What's under your hood?" It replaces the previous "Tried and true" tag that ran for more than two years.
The campaign, with spending estimated at $10 million, includes one 30-second spot and three :15s. In the :30, community workers try to hold back floodwater in a storm that also caused power outages; the workers use their car headlights to continue working through the night and in the morning are still able to start their cars.
In another spot, a car's lights are used to help a couple put together a swing set to surprise a child for her birthday.
