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 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, authorized Directed 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 VEHICLE.
ALL DOORS LEADING FROM ADJACENT LIVING AREAS 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 is responsible for having the
neutral safety feature 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 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.
OPERATION OF THE REMOTE START MODULE IF THE VEHICLE STARTS IN GEAR IS CONTRARY TO ITS INTENDED MODE OF
OPERATION. OPERATING THE REMOTE START SYSTEM UNDER THESE CONDITIONS MAY RESULT IN PROPERTY DAMAGE
OR PERSONAL INJURY. IMMEDIATELY CEASE THE USE OF THE UNIT AND REPAIR OR DISCONNECT THE INSTALLED REMOTE
START MODULE. DIRECTED WILL NOT BE HELD RESPONSIBLE OR PAY FOR INSTALLATION OR REINSTALLATION COSTS.
Remote starters for manual transmission pose significant risks if not properly installed and operated. When testing to ensure the
installation is working properly, only remote start the vehicle in neutral gear, on a flat surface and with a functional, fully engaged
parking brake. Do not allow anyone to stand in front of or behind the vehicle.
This product should not be installed in any convertible vehicles, soft or hard top with a manual transmission. Installation in such
vehicles may pose certain risk.

Introduction
The TL10 firmware for DS4+ is compatible with specific TOYOTA and LEXUS vehicles. It is a complete solution
for remote start, security (when security features are enabled), bypass, and features built in Bluetooth 4.0
allowing you to configure and control your system. This guide provides information on the installation of the
module as an analog unit, however a digital solution could be available for your vehicle. Please refer to the
DirectLink application or www.directechs.com for more information about which configuration is best for your
application.
Warning! This module is designed to be configured using the DirectLink application for mobile devices, however it can also
be configured using the web tool located at www.directechs.com. To download the DirectLink mobile application, please visit the
Google Play or Apple store.
