CRUISE CONTROL SWITCHES
Introduction
The cruise control is an automatic speed control
system that allows you to maintain a constant
cruising speed above 20 m.p.h. (32 km/h) without
depressing the accelerator pedal. The four (4)
control switches are located on the L.H. side
control panel (see page 2-5, item #2).
WARNING: Do not use the cruise control system
when driving conditions do not permit maintaining
a constant speed, such as in heavy traffic or on
roads that are winding, icy, snow covered,
slippery, or with a loose driving surface.
Setting vehicle speed
To turn on the system, push down "CRUISE"
rocker switch, set the vehicle speed by
accelerating to the desired speed, momentarily
press and release the "SET" switch, and then
remove your foot from accelerator pedal. This
sets the cruising speed and stores it in memory,
thus maintaining speed automatically.
NOTE: Cruise control system will not accept
speed settings, nor will the "RESUME" switch
operate, below approximately 20 m.p.h. (32
km/h).
Increasing set speed
Vehicle speed setting may be increased by one of
the following methods:
1. Press and hold the "RESUME" switch until the
desired speed is obtained. Releasing the
"RESUME" switch will set the new higher speed.

2. Depress accelerator pedal until the desired
speed is obtained, then press and release the
"SET" switch.
NOTE: When driving with cruise control in use,
the speed may be increased for passing, etc., by
depressing the accelerator in the usual manner.
Once the foot is removed from the accelerator
pedal, the cruise control will return to the set
speed.
Decreasing set speed
Vehicle speed setting may be decreased by one
of the following methods:
1. Press and hold the "SET" switch until the
desired lower speed is obtained. Releasing the
"SET" switch will set the new speed.
2. The cruise control can be disengaged without
losing the speed memory by either of two
methods:
a) Lightly applying the brakes, or
b) momentarily depressing the "DECEL" switch
button.
After either of these disengagements, you may
return to the previously set speed by pressing and
releasing the "RESUME" switch, provided the
speed is higher than 20 m.p.h. (32 km/h).
The cruise control is completely shut off and the
speed memory is lost when turning off the
"CRUISE" rocker switch.
NOTE: Cruise control is inoperative when speed
drops below 20 m.p.h. (32 km/h), therefore the
setting instructions must be repeated if vehicle
speed drops below this mark.
When the cruise control system is cancelled,
objectionable vehicle motions are minimized by
lightly depressing accelerator, before disengaging
cruise control.
WARNING: It is important to know that toggling
the "SET" or the "RESUME" switches will result in
a decrease or increase in speed (respectively) of
1 m.p.h. (0,6 km/h) for every touch.
VIDEO SYSTEM REMOTE CONTROL
Activate all video system components by
depressing power switch located on L.H. side
control panel (see item #13 on page 2-4).
To operate system from remote control, the
control power cord must be connected to the
video cassette player via remote control jack as

damaged diagram chart or without a diagram
chart. Install a dummy plastic card (Prévost part
no. 590251) if the coach is operated without a
diagram chart.
34. Tachometer
Indicates engine speed in hundreds of revolutions
per minute (rpm) and serves as a guide for proper
gear shifting. It also helps the driver in preventing
excessive engine speeds when going down steep
grades, with engine serving as a brake.
Maximum allowable engine rpm is 2450.
35. Pyrometer gauge (Optional)
Indicates exhaust manifold temperature in
hundreds of °F. Normal reading should vary
between 500 and 1100 °F according to operating
conditions. Temperature should not exceed
1100°F.
