General Information
Daimler Trucks North America LLC (DTNA), on behalf of its wholly owned subsidiary, Freightliner Custom
Chassis, Inc. (FCCC), is initiating Field Service Campaign SF633A to modify the vehicles mentioned above.

vehicle. A Dealer will be liable for any progressive damage that results from its failure to complete campaigns
before sale or delivery of a vehicle.
Owners may be liable for any progressive damage that results from failure to complete campaigns within a
reasonable time after receiving notification.
Please contact Warranty Campaigns for consideration of additional charges prior to performing the repair.

Work Instructions
Please refer to the attached work instructions. Prior to performing the campaign, check the vehicle for a
completion sticker (Form WAR261).

If our records show your dealership has ordered any vehicle(s) involved in campaign number SF633, a list of
the customers and vehicle identification numbers will be available on DTNAConnect.

IMPORTANT: When the campaign has been completed, locate the base completion label in the appropriate location on the vehicle, and attach the gray completion sticker provided in the field service kit (Form WAR261). If
the vehicle does not have a base completion label, clean a spot on the appropriate location of the vehicle and
first attach the base completion label (Form WAR259). If a field service kit is not required or there is no completion sticker in the kit, write the campaign number on a blank sticker and attach it to the base completion label.
