Brakes
Exhaust Brake (Pickup
Models only)
The heavy duty diesel pickups have
an exhaust brake to enhance the
vehicle brake system, and reduce
brake lining wear. A switch is used
to activate the system, and is
located below the climate controls in
the center of the vehicle instrument
panel. The switch must be pressed
at each vehicle start for the system
to be active. A light in the switch will
come on when the Exhaust Brake is
activated.
