Warning! Safety first
The following safety warnings must be observed at all times:
Due to the complexity of this system, installation of this product must only be•
performed by an authorized Directed Electronics dealer.
When properly installed, this system can start the vehicle via a command•
signal from the remote control. Therefore, never operate the system in an
area that does not have adequate ventilation.
The following precautions are the sole responsibility of the user; however, autho-
rized Directed Electronics dealers should:
Never use a test light or logic probe when installing this•
unit. Always use a multimeter.
Never operate the system in an enclosed or partially enclosed area without•
ventilation (such as a garage).
When parking in an enclosed or partially enclosed area or when having•
the vehicle serviced, the remote start system must be disabled using the
installed toggle switch. It is the user’s sole responsibility to properly handle
and keep out of reach from children all remote controls to assure that the
system does not unintentionally remote start the vehicle.
USER MUST INSTALL A CARBON MONOXIDE DETECTOR
IN OR ABOUT THE LIVING AREA ADJACENT TO THE VE-
HICLE. ALL DOORS LEADING FROM ADJACENT LIVING AR-
EAS TO THE ENCLOSED OR PARTIALLY ENCLOSED VEHICLE
STORAGE AREA MUST REMAIN CLOSED AT ALL TIMES.
Use of this product in a manner contrary to its intended mode of operation may
result in property damage, personal injury, or death. Except when performing
the Safety Check outlined in this installation guide, (1) Never remotely start the
vehicle with the vehicle in gear, and (2) Never remotely start the vehicle with the
keys in the ignition. The user will be responsible for having the neutral safety fea-
ture of the vehicle periodically checked, wherein the vehicle must not remotely
start while the car is in gear. This testing should be performed by an authorized
Directed Electronics dealer in accordance with the Safety Check outlined in
this product installation guide. If the vehicle starts in gear, cease remote start
operation immediately and consult with the user to fix the problem immediately.

After the remote start module has been installed, test the remote start module
in accordance with the Safety Check outlined in this installation guide. If the
vehicle starts when performing the Neutral Safety Shutdown Circuit test, the
remote start unit has not been properly installed. The remote start module must
be removed or properly reinstalled so that the vehicle does not start in gear. All
installations must be performed by an authorized Directed Electronics dealer.
OPERATION OF THE REMOTE START MODULE IF THE VEHICLE STARTS IN
GEAR IS CONTRARY TO ITS INTENDED MODE OF OPERATION. OPERAT-
ING THE REMOTE START SYSTEM UNDER THESE CONDITIONS MAY RE-
SULT IN PROPERTY DAMAGE OR PERSONAL INJURY. IMMEDIATELY CEASE
THE USE OF THE UNIT AND REPAIR OR DISCONNECT THE INSTALLED RE-
MOTE START MODULE. DIRECTED ELECTRONICS, INC. WILL NOT BE HELD
RESPONSIBLE OR PAY FOR INSTALLATION OR REINSTALLATION COSTS.

Installation points to remember
This product is designed for fuel-injected, automatic transmission vehicles only.
Installing it in a standard transmission vehicle is dangerous and is contrary to
its intended use.
➤ Virtual tach
Virtual Tach is a new feature for Directed this year. It is the default RPM-sensing
method for the new Responder LE hybrid keyless entry /remote start systems.
Virtual Tach gives the installer the performance of a hard wired tach wire, with
the convenience of voltage sensing. It is far superior to any voltage-sense feature
you’ve tried before.
Virtual Tach monitors the cranking voltage of the vehicle using a very fast micro
controller and an analog-to-digital converter. The microprocessor “saves” the
base voltage as a reference. When Virtual Tach “sees” the slightest uptick in
voltage, indicating that the alternator is charging the battery, the starter motor
shuts off instantly.
➤ D2D
The system has the ability to interface with an XK module through the D2D port.
The advantage to using a D2D interface is that there is less wiring involved in
the installation. Check the XK module installation guide to determine which wires
are not needed, and which options are available.

➤ Before beginning the installation
Please read this entire installation guide before beginning the installation.•
The installation of this remote start system requires interfacing with many of
the vehicle’s systems. Many new vehicles use low-voltage or multiplexed
systems that can be damaged by low resistance testing devices, such as
test lights and logic probes (computer safe test lights). Test all circuits with a
high quality digital multi-meter before making connections.
Do not disconnect the battery if the vehicle has an anti-theft-coded radio.•
If equipped with an air bag, avoid disconnecting the battery if possible.
Many airbag systems display a diagnostic code through the warning lights
after the lights lose power. Disconnecting the battery causes the anti-theft
code to be erased, which can then require a trip to the dealer.
If using an external LED or Valet Switch, check with the customer about•
where to locate the switch.
To avoid accidental battery drainage; turn off the interior lights or remove•
the dome light fuse.
Roll down a window to avoid being locked out of the car.•
➤ After the installation
Test all functions. The Using Your System section of the Owner’s Guide is•
very helpful when testing.
When testing, don’t forget that this system is equipped with Nuisance•
Prevention® Circuitry (NPC). NPC can bypass trigger zones, making
them appear to stop working. See the Nuisance Prevention® Circuitry
section of the Owner's Guide.
Review and complete the Safety Check section of this guide prior to the•
vehicle reassembly.

Component locations and finding wires
For detailed information on where to locate components, and how to find the
wires you need, please refer to the Direct Tech web site at www.directechs.
com.
➤Valet/program switch
IMPORTANT! When the vehicle is delivered, please show the user where this
switch is located and how to disarm the system with it.
Ensure that the location you pick for the switch has sufficient clearance to the
rear. The switch should be well hidden. It should be placed so passengers or
stored items (such as in a glove box or center console) cannot accidentally hit it.
The switch fits into a 9/32-inch hole.
This system has Remote Valet. The user can enter and exit Valet Mode without
having to reach the Valet/Program switch. This feature was introduced so that
switch location was less critical in day-to-day use. As long as the Valet/Program
switch can be reached to disarm without a transmitter, easy access is not im-
portant.

➤Status LED
Things to remember when positioning the Status LED:
It should be visible from both sides and the rear of the vehicle, if pos-•
sible.
It needs at least 1/2-inch clearance to the rear.•
It is easiest to remove a small panel, such as a switch blank or a dash•
bezel, before drilling a 9/32-inch hole.
Use quick-disconnects near the LED wires if the panel is removable. This lets•
mechanics or other installers remove the panel without cutting the wires.
