WARNING
The engine compression brake or ex-
haust brake is not intended as the pri-
mary brake for the vehicle, nor is it an
emergency brake. The service brakes
must be used in an emergency. Rely-
ing solely on the engine compression
brake or exhaust brake to stop the ve-
hicle in an emergency could cause an
accident and lead to personal injury.
The engine compression brake or ex-
haust brake only helps the service
brakes by using pressure to slow the
drive train. You must use the service
brakes for quick or emergency stops.
Failure to comply may result in death,
personal injury, equipment or property
damage.
"Control speed" is the speed at which the
forces pushing a vehicle down a grade are
equal to the forces holding it back.

WARNING
DO NOT use the engine compression
brake or exhaust brake when operat-
ing on road surfaces with poor traction
(such as wet, icy, or snow covered
roads, or gravel). The engine com-
pression brake or exhaust brake can
cause the wheels to skid on a slippery
surface. You could lose control of the
vehicle and/or jackknife if the wheels
begin to skid, resulting in an accident.
Failure to comply may result in death,
personal injury, equipment or property
damage.
CAUTION
The engine ECM maintains a record of
maximum rpm. Exceeding the maxi-
mum rpm will be considered driver
abuse and will affect the engine war-
ranty. See Engine Specifications.
