The engine brake is NOT intended as the primary brake for
the vehicle, nor is it an emergency brake. The engine brake
only helps the service brakes by using pressure to slow the
drivetrain. Use the service brakes for quick stops.
WARNING! Do not drive with frequent or contin-
uous use of the service brakes. This can over-
heat the brakes and result in excessive lining
wear, increased stopping distances, possibly an
accident and may lead to personal injury. Before
descending a steep grade, shift to a lower gear,
keep the vehicle speed low, and avoid continu-
ous application to the brakes.
NOTE: The longer or steeper the hill, the more
important it is to use your engine brakes. Make max-
imum use of your engine brakes by gearing down
and letting the engine brakes do the work.
