COLUMBUS, Ind. (August 26, 2002) - Cummins Inc. today introduced an Uptime Guarantee program for its heavy-duty on-highway truck engines subject to the tough new October emissions requirements. The program provides assurance to the trucking industry that the new engines will meet and exceed customer performance and reliability needs.

Under the guarantee, if any part on a customer's ISX or ISM engine fails and can't be repaired within a 24-hour period, Cummins not only will pay for the repairs, but also will provide a rental vehicle at no cost.

"The ISX engine is proven, tested and reliable. We certified this engine early, we've tested it thoroughly, and now we're pleased to offer our customers an Uptime Guarantee on the ISX, as well as the ISM which will be certified later this fall," said Tom Kieffer, Cummins executive director - marketing. "The cooled EGR subsystem, based on the already proven performance of the ISX and ISM engines, has undergone more real-world testing than any new product launch in our history," added Kieffer. "As a result, we are announcing this program to the industry to eliminate any concern customers may have in purchasing our new products."

The Uptime Guarantee applies to Cummins ISX and ISM engines purchased between Oct. 1, 2002, and March 31, 2003, with coverage from the date of purchase through Dec. 31, 2003.

Separately, today Cummins announced three new extended warranty options for its heavy-duty engines. All the new components are fully covered in Cummins base warranty. The new extended warranty offerings further strengthen confidence in Cummins new products.

"We are ready for October 2002," said Christine Vujovich , vice president - environmental policy and product strategy. "Cummins has never wavered from its commitment to our customers to have the most reliable product available to meet the EPA deadline."

The EPA certified the first Cummins engine in April of this year, the second in August, and Cummins submitted its third engine for certification on August 23 to complete a lineup of engines compliant to the strict new standard.
