SAFETY
The safest and most advanced
truck we've ever built.
Detroit Assurance Suite of Safety Systems
Internally mounted protection from the elements. Greater durability to prevent sagging -- a common problem with piano hinges.
Introducing Detroit Assurance
Technology gets tough in the 49X, the first Western Star to feature the most advanced suite of active safety systems ever offered to the vocational market - Detroit Assurance. But it not only helps keep people safe, it helps you reduce the repair and operational costs of having a truck out of service by avoiding collisions - which can mean game-changing productivity to you.
Active Brake Assist 5 detects distance and speed to moving and stationary objects in its path and determines if warning or braking is necessary. It's the only system on the market that works down to 5 MPH*, making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck's path, alerting the operator while partially braking, followed by full braking if the operator does not react.
* with DT12 Transmission
A game changer for safety in and around busy jobsites, Side Guard Assist detects objects on the passenger side of the truck and alerts the operator.
Detroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control to 0 MPH* and Tailgate Warning to ease driving in stop and go traffic, as well as help reduce collisions as operators travel from one jobsite to the next.
