Compression Brake
With the
compression brake switch
ON, the brake automatically creates its
braking effect when you remove your
foot from the accelerator pedal.
The brake
switch is located on the
accessory dash panel. It controls
whether the brake is ON (ready to slow
the vehicle down) or OFF (no braking
action).
• Do not use the engine
compression brake to slow
the vehicle down when you are
bobtailing or pulling an empty
trailer.
• Make sure the brake is OFF before
starting the engine.
• After the engine is started, warmed
up, and you are ready to get under
way, turn the engine compression
brake switch ON for added braking
effect.
