PROGRAMMING TRANSMITTERS
To use the transmitter with your alarm/starter
system, you must first have the system learnthe transmitter's code. The system can
learn a total of 4 transmitters. If more than 4
transmitters are programmed, the oldest codes
will be replaced.
(The same transmitter can be coded 4 times to
lock out all other transmitters.)
The AS-4563/4564/4565 systems feature
Multi-car operation.
This allows the owner of two Autostart
systems in two of his/her vehicles to control
both systems with one transmitter. (Both
vehicles must be equipped with an AS4563/4564/4565.
The remote transmitter of the primary
vehicle can control the starter disable
system, the door locks and the remote car
starter operation of the second vehicle.
The remote transmitter of the second vehicle
can also operate the primary vehicle
REMOTE STARTER & ALARM VALET
MODES
The alarm/starter unit can be placed in
Remote Starter Valet Mode to disable the
capability of starting the engine by the
unit while maintaining the alarm and door
locking/unlocking functions. This is
recommended if the vehicle is to be parked
in a garage or if the vehicle needs to be
serviced.
NOTE: In order to program a new transmitter
code, Alarm Valet Mode must be disabled.
Also, when programming the transmitter, make
sure that no other transmitter is in use or the
alarm/starter unit may learn it.
1.Make sure that the Alarm Valet Mode is
disabled.
2. Turn the ignition switch to ON
3.Open the hood
4.Turn the Valet switch ON, OFF, ON
5.The parking lights will come ON. You
have up to 5 seconds to press Button Ion the transmitter to be added to the
unit, if the operation is successful, the
alarm/starter unit will flash the parking
lights 5 times quickly.
Note that the Alarm Valet Mode is enabled at
the end of this procedure. You should disable
it to return to normal operation. If the code
could not be read by the unit, repeat the
operation from step 1. If you cannot program
the unit after several tries, there may be a
problem with the transmitter or remote starter
unit.
The alarm/starter unit can also be switched
to Alarm Valet Mode to stop an alarm
condition or to disable the alarm functions
and the anti-theft starter kill feature. While
in the Alarm Valet Mode, the remote starting
capability, the panic mode and door
locking/unlocking functions are still
operational.
NOTE: Enabling Alarm Valet Mode is
required if you want to stop the initialalarm condition that occurs when
powering-up the system.
Using one of the next options will permit the
user to place the alarm/starter in any one of
the following combinations using the
single valet switch:
•Normal operation
•Alarm valet mode only
•Starter valet mode only
•Alarm and starter valet modes

TRANSMITTER FUNCTION
Once programmed, the transmitter will be
operational. (Hood must be closed)
The transmitter is depended on the module
type.
*The STOP Button on AS-4565 has NO
function.
NOTE: Pressing any button with the vehicle
running, parking brake engaged and the doors
closed, will put the unit into Ready Mode.
TACH ADJUSTMENTS
Autostart systems have two methods of fine
tuning the tach signal that is generated from
the vehicle, the first method is manual tach
search and setting, and the second is
automatic tach search and setting. Either
method can be used, however an automatic
search is recommended. Tach adjustment
procedures should be done every time a
new unit is installed. This is because the
tach signal from some ignition systems can
sometimes be too high or too low, thus
causing failed starts under different
temperatures.
The procedures for tach adjustment are as
follows:
1. Hold hood switch down for 6 seconds
2. Release pinswitch (parking lights should
come on)
3. With parking lights on, immediately push
and release pinswitch again.
NOTE: A manual adjustment should only
be done if the auto setting is not
completing the crank cycle properly in
cold weather.
MANUAL TACH SEARCH AND
SETTING
1. Hold hood switch down for 6 seconds
2. Release pinswitch (parking lights should
come on)
3. With parking lights on, immediately push
and release pinswitch again.
4. Parking lights will stay on for 20 sec. (if
not repeat from step 1)
5. Press Channel 3 (Trunk) of remote
transmitter at the same time (lights will
flash 1 to 7 times)
6. Now you can increase or decrease the
tach setting, depending on your needs.
7. Channel 1(LOCK) will decrease the
setting, and channel 2 (START) will
increase the setting.
8. After proper setting has been reached,
push Channel 3 (Trunk) to save setting.
(parking lights should flash once long)
CUSTOM PROGRAMMING OPTIONS
Autostart systems are equipped with 2
custom programming menus that allow the
user to custom fit the system according to
the installation requirements.
These options are designed to help make
interfacing with all vehicles possible.
To get into custom programming mode
you must do the following:
1. Hold pin-switch down for 6 sec.
2. Release pins-witch (parking lights will
come on)
3. Immediately push and release
pins-witch once again. (parking lights
will stay on for 20 sec.)
4
4. Press and hold brakes, and press 1 or 2
on remote transmitter. (Button 1 for
mode one, and Button 2 for mode two)
(lights will flash once for mode 1 and twice
for mode 2)
After you have entered into one of the two
programming menus you can release the
brake pedal. The unit will stay in programming
mode until the hood pins-witch is pressed or
the valet switch has been turned off. (so take
your time to make the proper selection)
The menu will automatically start you at
function one, once you choose from one of the
three Options, you will automatically jump to
the next function.
To select one of the three options press the
appropriate transmitter button. (see below)
1. Channel 1 (LOCK) = Option 1
2. Channel 2 (START) = Option 2
3. Channel 3 (TRUNK) = Option 3
Once an option has been selected the parking
lights will flash 1,2 or 3 times. (Depending on
option selected)

TACH WATCH LOCKOUT
Tach Watch lockout is a safety feature built
into the remote starter to protect the
vehicle’s starter motor. If, during remote
start, the vehicle’s engine ever cranks the
entire programmed crank time without
detecting any tach pulses during the first
crank cycle, the unit will go into tach watch
lockout. The diagnostics for this is 3 quick
parking light flashes when trying to remote
start the vehicle.
If your module is in Tach Watch Lockout it is
indicating that a problem exists with the tach
signal it is receiving. Verify that the tach
wire from the remote starter is properly
connected to a good tach signal in the
vehicle.
To remove the unit from Tach Watch
Lockout you must do the following:
5
1. Close the hood
2. Disable starter kill (if installed)
3. Start the engine using the key.
4. Let it run for at least 25 seconds, then shut
it off.
5. The module should now be out of Tach
Watch Lockout.
NOTE: If module is still in Tach Watch Lockout
move tach wire to a better tach source and
perform an Automatic Tach Setting. Repeat
steps 1 to 5.
DIESEL ENGINES
All systems are equipped with a dedicated
“GLOW PLUG” input (pin #14).
This input must be wired to the “Wait to Start”
light in the vehicle and must receive 12 volts
for as long as the light is on. When this input
is used a protection diode must be installed on
the brake input.
Note: Diesel mode must be programmed for
this to work.
*NOTE: The unit will notify the user that it
has exited Ready Mode by giving three
slow flashes of the vehicles parking
lights.
CLUTCH BYPASSING
Most manual transmission vehicles will
require the clutch to be pressed in order
for the vehicle to crank. This being true
under remote start as well, so a clutch
bypass must be performed.
A simple thing to look for when performing a
bypass, is the make of vehicle you are
working on, typically most domestic vehicles
have a direct feed wire at the clutch switch,
this means that the starter wire in the vehicle
becomes continuous with +12volts when the
clutch is pressed.
While import cars typically have a relay that is
controlled with the clutch pedal. This means
that when the clutch is pressed it will send a
signal to a relay, allowing the vehicle to start.
PARKING BRAKE WIRE
SETTING THE UNIT INTO READY MODE
The unit does not come with channel 2
operational from the box.
What this means is that to remote start the
vehicle you must first get the unit into Ready
Mode.
To get into ready you must do the following:
1. Close all doors.
2. Make sure shifter is in neutral.
3. Start vehicle with the key.
4. Apply the Parking brake
5. Within 20sec. Push any button on
transmitter (Lights will flash 3 times
quickly, and stay on)
6. Remove the key vehicle will stay running.
7. Exit the vehicle and close the door.
8. Press and hold any button until the vehicle
shuts down.
The vehicle will now be in ready mode, to start
press button 2 on the transmitter.
REMAINING IN READY MODE
Once the vehicle is in Ready Mode you can
start and stop the vehicle at will.
However, should any of the following occur the
vehicle would come out of Ready Mode thus
eliminating the remote start option until Ready
Mode is restored.
1. Doors opened.
2. Hood opened.
3. Brakes pressed.
4. Parking brake disengaged.
5. Key turned to the on position.
Should any of the above occur, ready mode
will be cancelled.
The system has a parking brake input;
this input is used as part of the Ready
Mode sequence and must be connected.
This input is supposed to be a ground.
All vehicles are equipped with a parking
brake, and all use a negative signal.
The easiest location to find this wire is at the
parking brake housing, there will usually only
be one wire coming of the housing thus
eliminating the chance of error.
PROGRAMMABLE 5th RELAY
The 4500 series car starters are equipped
with a high current, programmable 5th relay
onboard that can be used to power a second
ignition, accessory, or crank wire.
The programming is very simple, the unit
uses a series of 3 jumpers, each jumper
represents a function, in order to activate
any one of the three possible 2nd outputs,
you must place the jumper(supplied) on one
of the three pins and simply connect the
14awg wire to the vehicles second
ign/acc/crank wire.
NOTE: ONLY ONE OF THE THREE
JUMPERS CAN BE USED AT ONE TIME.
6
TURBO MODE
OEM recommends that any turbo equipped
vehicle should idle down for a min. period of
60 sec after hard driving, to avoid the risk of
turbo damage.
Most people today don’t have the time to sit in
their cars for 60 sec. To wait for their turbo’s to
cool, so the result in most cases is that the
turbo vehicles are not let to idle.
Autostart has addressed this problem with the
addition of Turbo Idle Down Mode.
This great feature will allow the user to place
their manual vehicle into ready mode, exit the
vehicle, hold the transmitter button for 4 sec.,
and walk away, it’s that simple.
The system will automatically lock and arm the
vehicle, but the engine will continue to run for
60 sec.
To enable Turbo Mode, do the following:
(1) See Setting up ready mode page.6
(2) Replace step 8, by holding the transmitter
button for 4sec. Or until the parking light
come back ON.
8. Press transmitter button within 5
seconds to program transmitter.
•See Custom Programming options for
default settings.
SOME COMMON QUESTIONS AND
ANSWERS
The following are some commonly asked
questions about our product, followed by
possible answers.
Q: Does the parking brake wire have to be
connected?
A: Yes the parking brake wire must
absolutely be connected.
Q: Do both door trigger wires on have to be
connected?
A: No, only one of the 2 trigger wires must
be connected, or the unit will not enter ready
mode.
(refer to wire guide for proper polarity)
Q: Unit gives me one long flash when
getting into ready mode instead of three,
and shuts off when key is removed.
A: The long flash indicates that there is a
problem with the tach signal you are using.
Locate another tach wire or perform an
automatic tach learn.
Q: Can the vehicle start in gear?
A: No. Because the unit see the vehicle shut
down by remote once the user has exited
the vehicle. Knowing that the vehicle was
running when it was exited indicates that the
vehicle is in neutral.
