heater, and electric or diesel-fired engine-coolant pre-
heaters can be operated in the off position (regard-
less of whether the key is inserted).
In the ACCESSORY position, the key is turned coun-
terclockwise. The auxiliary (bunk) fan, windshield
fan(s), radio or stereo system, mirror heat, ether start
system, air dryer, backup lights, and all of the electri-
cal systems that are operable in the off position are
operable in the accessory position.
In the ON position, the key is turned clockwise and
all electrical systems are operable. The low air pres-
sure and low oil pressure warning lights (or mes-
sages) and buzzer operate until the engine is started
and pressure is built up.
Cruise Control
IMPORTANT: On vehicles with Eaton VORAD
Collision Warning System (CWS) with Smart-
Cruise, see the "Collision Warning System"
headings in this chapter before operating cruise
control.
The cruise control is activated by the SPD CNTL (on/
off) and RSM/ACC–SET/CST switches on the dash
(Fig. 2.19),
or
by optional PAUSE, RESUME, and
SET buttons on the transmission shift knob
(Fig. 2.20). The minimum speed at which cruise con-
trol can be used is 30 mph (48 km/h). The minimum
and maximum speed cruise control set limits can be
programmed, by authorized personnel, into the en-
gine electronics.
WARNING
Do not use the cruise control system when driv-
ing conditions do not permit maintaining a con-
stant speed, such as in heavy traffic or on roads
that are winding, icy, snow-covered, slippery, or
roads with a loose driving surface. Failure to fol-
low this precaution could cause a collision or
loss of vehicle control, possibly resulting in per-
sonal injury or property damage.
CAUTION
Do not attempt to shift gears without using the
clutch pedal when the cruise control is engaged.
Failure to follow this precaution will result in a
temporarily uncontrolled increase in engine
speed; transmission damage and gear stripping
could result.
