SySTEM PARk (FIguRE 2)
With both buttons in for normal run modes, the parking 
brakes on both the tractor and trailer may be actuated 
by pulling the yellow (parking brake) button out—which 
exhausts the air from the tractor spring brakes and 
simultaneously causes the red (trailer supply) button to 
pop out, applying the trailer brakes. This complies with 
Federal Regulations that one control must apply all the 
parking brakes on the vehicle.
