FRANKLIN, Tenn. -

The calendar may say that summer is behind us, but at Nissan, it just keeps rolling along.

Nissan has announced the launch of its Keep Summer Rolling vehicle giveaway and service sweepstakes, to promote proper vehicle maintenance.

The contest runs through Sept. 30, with online entries to be accepted through Oct. 31.

Nissan said Keep Summer Rolling is designed to help the company reconnect with current vehicle owners, and encourage them to keep their vehicle in top condition.

Through the contest, current Nissan owners are eligible to win one of three new Nissan vehicles or hundreds of service options meant to extend the life of their vehicles.

John Spoon, vice president of Nissan North America’s parts & service division, said, “With so many competing priorities during the summer families often put off servicing their vehicle, and this sweepstakes presents two great opportunities for our customers — a reminder to have Nissan-trained experts care for and prepare their vehicles for the fall and winter months ahead as well as the chance to win a 2013 Nissan Altima, Pathfinder or 370Z.”

The program encourages owners to keep their vehicles running in prime condition by using Nissan’s advanced diagnostics, factory-trained technicians and genuine parts available at their dealerships, the company said.

Existing customers receiving vehicle service at Nissan dealerships through Sept. 30 are eligible, and are entered in the sweepstakes by having their VIN and/or repair order submitted online at www.keepsummerrolling.com.

In addition to a chance to win one of three 2013 Nissan vehicle models including the Altima, Pathfinder and 370Z, customers are also eligible to win various service prizes including a one- or two-year maintenance-plus service contract, accessory vouchers and One-To-One Rewards Points, a customer loyalty program.

Nissan customers will receive promotional service incentives via mail and email regarding the Keep Summer Rolling Sweepstakes, which may include oil and filter changes, and parts and service offers for discounted tires, brake service, parts and labor or super-saver packages, the company reported.
