VEHICLES WITH AUTOMATIC TRANSMISSION
OPERATING INSTRUCTIONS
In the regulator box of your Speed Control is a
safety switch which will not let the system operate
until your vehicle is moving above a pre-selected
low speed. At the factory this "low speed switch"
is set to close between 27 and 33 mph; it should,
however, be checked during the Road Test.
The Control Switch is the switch you use to operate
all features of the system described in the
following paragraphs. It is installed near the turn
signal lever.
Set Speed - On the control switch, move the slide
button to the ON position and drive at any speed
above 32 mph at which you want automatic
control. Hold that speed with your foot while you
press and release the SET/COAST button. One
second after release, take your foot off the
accelerator pedal.
You can increase speed at any time with the
accelerator pedal. When you release the pedal, you
wi II retu rn to the set speed.
Acceleration • Hold the slide button in the
RESUME/ACCELposition and your vehicle will
accelerate until you release it, then your vehicle
will slow to your set speed and again control there.
If you want to make the higher speed your new set
speed, release the slide button when you reach the
speed you want, and as you do, quickly press and
release the SET/COASTbutton. Remember, you set
speed as you release the button - Not when you
press it.
COAST· When you press and hold the SET/COAST
button, you erase the set speed from the
regulator's memory and allow the vehicle to coast.
Just before you reach the lower speed you want,
release the button and it will control there,
providing it is above the low speed setting.
DISENGAGEMENT· Depress the brake pedal about
an inch and you are again in control of the vehicle
speed. You can also disengage the Speed Control
by pushing the slide button to OFF, but this erases
the set speed from the regulator's memory.
RESUME· When you disengage the system with
the brake, you do not erase the set speed from the
regulator's memory, even if you come to a
complete stop. To return to your chosen speed,
drive to a speed above 32 mph, then move the slide
button to the RESUME/ACCEL position and release
it. The Speed Control will take you back to your set
speed and control there.
If the rate of acceleration is faster or slower than
you like, drive with the accelerator to a speed close
to the set speed, then slide the button to the
RESUME/ACCEL position and release It.
UNUSUAL CONDITIONS • When the regulator is
adjusted right, your selected speed should be held
within plus or minus 4 mph, as long as grades do
not exceed 7% (most interstate highways). Since
the Speed Control is vacuum operated, this speed
range will widen as you drive at higher altitudes.
When you are pulling an extra heavy load,
climbing a very steep hill, or bucking a severe head
wind, a much wider than normal throttle opening
is needed.
The way to handle these occasional problems is to
bring the vehicle up to speed with the accelerator
pedal - and then let the Speed Control take over
again.
There is no drain on the battery when the ignition
switch is off - even if the control switch is left on.
WARNING
Do not use your Speed Control on slippery roads,
nor in heavy traffic.
