General Information

On behalf of the entities listed below, Daimler Truck North America LLC (DTNA), is initiating Field Service Campaign SF705
to modify the affected vehicles.

= Freightliner Trucks Division

= Wholly owned subsidiary, Western Star Truck Sales, Inc.

PROBLEM: The steel fuel tank standpipes do not meet the previous brass standpipe durability and are breaking,
causing the Espar heater not to function.

SOLUTION: A Daimler Truck North America authorized service facility will inspect and install a new nickel-plated
brass standpipe as needed.

There are approximately 37,000 vehicles involved.
Revision: An additional group (Group G) has been added and some VINs have been moved from Group D to Group G.
Additional Repairs

Dealers must complete all outstanding Recall and Field Service campaigns prior to the sale or delivery of a 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

(Form WAR261).

IMPORTANT: OWL must be viewed prior to performing the recall to ensure the vehicle is involved and the campaign has

U.S. and Canadian dealers, contact the Warranty Campaigns Department via Web inquiry at DTNAPortal.com/WSC, if you
have any questions or need additional information. Export distributors, submit a Web inquiry or contact your International
Service Manager.

U.S. and Canadian Dealers: To return excess kit inventory related to this campaign, U.S. dealers must submit a Parts
Authorization Return (PAR) to the Memphis PDC. Canadian dealers must submit a PAR to their facing PDC. All kits must
be in resalable condition. PAR requests must include the original purchase invoice number. Export Distributors: Excess
inventory is not returnable.

The letter notifying U.S. and Canadian vehicle owners is included for your reference.

Please note that the National Traffic and Motor Vehicle Safety Act, as amended (Title 49, United States Code, Chapter
301), requires the owner's vehicle(s) be corrected within a reasonable time after parts are available to you. The Act states
that failure to repair a vehicle within 60 days after tender for repair shall be prima facie evidence of an unreasonable time.
However, circumstances of a particular situation may reduce the 60-day period. Failure to repair a vehicle within a
reasonable time can result in either the obligation to (a) replace the vehicle with an identical or reasonably equivalent vehicle,
without charge, or (b) refund the purchase price in full, less a reasonable allowance for depreciation. The Act further prohibits
dealers from selling a vehicle unless all outstanding recalls are performed. Any lessor is required to send a copy of the recall
Notification to the lessee within 10 days. Any subsequent stage manufacturer is required to forward this notice to its
distributors and retail outlets within five working days.

Copy of Notice to Owners

Subject: Espar Fuel Standpipe Weld

Daimler Truck North America LLC (DTNA), on behalf of its Freightliner Trucks Division, and wholly owned subsidiary,
Western Star Truck Sales, Inc. is initiating Field Service Campaign SF705 to modify specific model years 2024-2025
Freightliner Cascadia vehicles; and Western Star 47X, 49X, and 57X vehicles manufactured February 14. 2023, through
April 3, 2024.

The steel fuel tank standpipes do not meet the previous brass standpipe durability and are breaking, causing the Espar
heater not to function.

A Daimler Truck North America authorized service facility will inspect and install a new nickel-plated brass standpipe as
needed.

Please contact an authorized DTNA dealer to arrange to have the campaign performed and to ensure that parts are available
at the dealership. The campaign will take approximately one and a half hours and will be performed free of charge. To
locate an authorized dealer, search online at Daimler-TruckNorthAmerica.com/Contact-us. Scroll down to “Locate a Dealer”
and select the appropriate brand.

This Field Service Campaign will terminate on December 31, 2025. Please make sure the campaign is completed prior to
this date. Work completed after this date will be done at the customer's expense.

caused by failure to properly maintain your vehicle. Daimler Truck North America LLC considers the work necessary under
this campaign to be proper maintenance and will, therefore, not pay for any damage to your vehicle caused by your failure
to have the repairs that are the subject of this campaign performed in a reasonable time.

SF705 — Inspection and Replacement of the Espar Fuel
Standpipe

Revision: An additional group (Group G) has been added and some VINs have been moved from Group D to Group G.

1. Check the base label (Form WAR259) for a completion sticker for SF705 (Form WAR261), indicating this work has
been done. The base label is usually located on the passenger-side door, about 12 inches (30 cm) below the door
latch. If a completion sticker is present, no work is needed. If a completion sticker is not present, go to the next step.

2. _ Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.

3. Disconnect the negative battery cables from the main and auxiliary batteries.

IMPORTANT: Vehicles in population G have two fuel tanks, and only the left-hand side fuel tank is equipped with an Espar
heater. Inspect (and replace, if required) only the left-hand side Espar heater. DO NOT replace the right-hand side heater.

4. Locate the auxiliary heater fuel metering pump and standpipe mounted on top of the fuel tank.
5. Inspect the fuel standpipe to determine the material type of the fitting threaded to the fuel tank (7/8-inch hex fitting).
0 If abrass standpipe is installed, as shown in Fig. 1, no further action is required. Go to step 16.
0 If anickel-plated steel (shiny/chrome at 7/8-inch hex) standpipe is installed, continue with step 6.

standpipe. For instructions, see Group 31 of the applicable workshop manual.

7. Remove the electrical harness connector and fuel line from the fuel metering pump. Mark the mounting location of the
pump, so it can be installed later in the same direction.

8. Clean the debris from the threads and remove the fuel metering pump from the standpipe while holding the standpipe
hex with a 7/8-inch wrench. See Fig. 2.

9. Clean the debris from the threads and remove the fuel standpipe from the fuel tank.

IMPORTANT: Some vehicle configurations require using cab airbags to raise the cab height to fully extend and
carefully remove the standpipe without bending it. The best clearance is usually achieved by moving the fuel standpipe
upward and inward towards the center rear of the cab. The upper bolts on the cab suspension shocks can also be
removed for additional clearance, allowing the cab airbags to extend fully. Before removing the fuel standpipe, use
blocks or an equivalent to secure the cab at full extension.

0 If the standpipe can be removed, go to step 11.
0 If the standpipe cannot be removed due to lack of clearance, continue with step 10.

10. Itis necessary to remove the fuel tank for vehicle configurations with insufficient space in the cab for fuel standpipe
removal and replacement.

10.1. Pump, drain, and transfer all fuel from the fuel tank containing the auxiliary heater standpipe. For instructions
to remove the fuel tank, see Group 47 of the applicable workshop manual.

10.2. Clean the area at the top of both fuel tank straps and mark the location of the fuel tank within the tank straps.
