or disengage the engine brake. Refer to Chapter 13
for instructions on using the engine brake.
Engine Fan Switch
The engine cooling fan can be turned on by the en-
gine fan switch.
To turn the engine fan on, press the upper half of the
switch. The fan will continue to operate for a set
amount of time and then turn off unless the coolant
temperature is high enough to continue fan opera-
tion. To turn the fan off before the set time period
ends, press the lower half of the switch. See
Fig. 5.17.
Hill Start Aid Override Switch
Some vehicles are equipped with a Hill Start Aid
(HSA) feature to prevent the vehicle from rolling
while on steep grades and to allow for a controlled
launch. HSA is "on" by default. It can be turned off
by pressing and releasing the HSA override switch
on the dash (see
Fig. 5.18).
PTO Switch
To activate the PTO function, press the upper half of
the switch. Press the lower half of the switch to de-
activate the PTO function. See
Fig. 5.19.

To avoid injury, do not install a PTO that is not

PTO with a Detroit Transmission could result in
unintended operation which could lead to severe
personal injury.
