This manual provides information needed to operate and understand the vehicle and its components. More detailed information is contained in the Owner’s Warranty Information for North America booklet and in the vehicle’s workshop and maintenance manuals.
Custom-built Western Star vehicles are equipped with various chassis and cab components. Not all of the information contained in this manual applies to every vehicle. For details about components in your vehicle, refer to the chassis specification pages included in all new vehicles and to the vehicle specification decal located inside the vehicle.
This vehicle must be regularly inspected and maintained as indicated in the Western Star Maintenance Manual, and in the Pre- and Post-Trip Inspections and Maintenance chapter in this manual, in order to continue satisfactory performance and ensure coverage of the vehicle under the manufacturer’s warranty.
Many maintenance procedures ensure that the vehicle and engine continue to comply with applicable emissions standards. Maintenance procedures, using components engineered to comply with greenhouse gas emissions and fuel efficiency regulations, may be performed by an authorized Daimler Trucks North America dealer, an independent outlet, or the vehicle owner or operator.
The vehicle owner is responsible for determining the suitability of replacement components to maintain compliance with federal and local jurisdictional regulations. Components including, but not limited to, tires, cab/sleeper side extenders, chassis fairings, bumper, hood, vehicle speed limiters, and idle reduction timers are specifically designed and manufactured to exacting standards for regulatory fuel efficiency and greenhouse gas emissions compliance. It is important that these components are always replaced with components that meet or exceed the performance of the originally installed components.
Reporting Safety Defects
If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Western Star Trucks. If the NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or Western Star Trucks.
