I have a 2003 M1078A1 the button labeled warmup/off/retard.
I’ve just realized hope wonderful that switch is when switched to retard. That is how you activate the exhaust brake. I’ve never driven a vehicle with this feature and love how well it works and will save my brake shoes from excessive wearing especially on down hill descents. But my true question is does anyone know if when it is turned on and after I take my foot of the throttle the exhaust brake activates and the light in the dash comes on that says “EXHAUST BRAKE” when this is occurring does it also illuminate the brake lights? I just don’t want to get rear ended. Also note that as soon as I press the brake or accelerator the light goes off and everything resumes normal operation.
