1) Turn the ignition key “On”, then “Off”.
2) Within 7 seconds press the Valet Switch 5 times.
The Status Lights will flash twice, and if the horn is connected, it chirps twice.
The parking lights turn on, and stay on while in programming mode.
3) Select the feature to be changed by pressing the Valet Switch the same number of times
as the feature number (example: feature
#
3 = 3 presses).
The Status Lights will flash the same number as the Valet Switch presses just
entered. If the horn is connected, it also chirps the same number.
Count the number of flashes or chirps to confirm that the desired feature has been
chosen (if needed, reenter the Valet Switch presses).
4) Once the feature has been confirmed, press the transmitter buttons as follows:
“LOCK” = Feature’s Default 1st setting (
1 Status Light flash & 1 horn chirp)
“UNLOCK” = Feature’s optional 2nd setting (
2 Status Light flashes & 2 horn chirps)
•
Most of the programmable features offer more than one optional choice:
“START” = Feature’s 3rd setting (
3 Status Light flashes & 3 horn chirps)
“TRUNK” = Feature’s 4th setting (
4 Status Light flashes & 4 horn chirps)
Once the Status Lights flash a response, and the horn chirps the response
(if connected), the feature is set.

How to program the features:
cess. Consider both methods before selecting one to use, and then connect the
Black/Yellow wire accordingly. Either connection method must be performed at
the completion of the installation, after all other wiring connections are made.
Smart Start sensing is more commonly used, for its ease of installation. The unit as
received has Smart Start selected. Smart Start “reads” the vehicle’s battery voltage level
via the Black/Yellow wire to determine engine running status. To use Smart Start:
1) Connect the Black/Yellow wire to constant “Battery” 12 volts. This may done at the
ignition switch harness, or at the battery itself for better sensitivity.
2) Switch the selector slide switch on the MARS control module to the left toward the
module corner (see page 21 and the markings on the control module).
3) Adjust Smart Start by starting the engine and turning the left adjustment screw on the
control module slowly clockwise until the indicator LED starts flashing. Turn the adjust-
ment until the LED is flashing in a consistent and regular manner.
4) Test the operation by remote starting and checking that the indicator LED shows the
same consistent flashing (good voltage signal learned), and that the starter engage-
ment is long enough for the engine to start, but without grinding. Turn clockwise for
more crank time and counterclockwise for less crank time.
Tach Wire sensing is generally more reliable, and preferable in cases were the engine
normally starts inconsistently, or is hard to start . With this method the Black/Yellow wire
reads the engine speed (tach) information directly from a wire in the vehicle. To use the
Tach Wire method:
1) Connect the Black/Yellow wire to the vehicle's tach wire, which is found in the engine
compartment, although in many cases it may also be located inside the vehicle. To use
a multimeter to verify the correct tach wire, set it for AC Volts scale. The correct wire will
