Kenworth has improved its medium-duty models with the introduction of enhanced multiplex instrumentation, the Driver Information Center seen on its class-8 trucks, and more modern dash styling.
 
The new, "state of the art" multiplex instrumentation system can be ordered on all Kenworth T170, T270 and T370 models with 2010 engines. Its benefits: increased serviceability and reliability with wiring behind the dash color-coded and numbered for easier servicing, and critical connections maintained with positive locking connectors. The system is supported by the Kenworth Electronic Service Analyst, a computer-based diagnostics tool that simplifies troubleshooting.
 
The multiplex system is incorporated into a more modern and ergonomic dash. It sports a new speedometer and tachometer cluster with 2-in.-diameter gauges, an engine hour meter, odometer, trip odometer, and outside temperature gauge. A diesel particulate filter (DPF) status indicator lamp, high exhaust system temperature (HEST) warning lamp, and seatbelt reminder light are included. LED back-lighting is used in the face plate and pointers, and the dash rocker switches contain LED indicator lights.

The Kenworth Driver Information Center provides instant trip access information for miles per gallon, engine and idle hours, idle percentage and optimum rpm range. A “sweet spot indicator” offers visual cues when the optimum rpm is reached, while a bar graph displays current mpg against trip average mpg.
