well as bringing awareness to any operational or vehicle limitations.

Vehicle Takeover Refer to the Quick Reference Guide section for more details.
Firmware notes
Immobilizer bypass: This firmware does not support Immobilizer bypass. One (1) programmed OEM key must be wired into the
vehicle to complete the installation of a remote starter.
RSR:
•RSR installations are not compatible with vehicles equipped with a manual transmission.
•Remote Start Ready (RSR) is a function that enables the interface module to remote start the vehicle completely on its own
Consequently, there is no need for an aftermarket or an OEM remote starter in order to start the vehicle from a distance.
SmartStart Compatible: SmartStart is equipped with D2D, which means it can be connected to an interface module and used in
Remote Start Ready (RSR) mode without the use of a remote starter. See "Module programming" for more information.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
Refer to the "Vehicle connections" following the installation diagram.
Footnotes
[1] Hood pin: The installation of an aftermarket hood pin is only required on vehicles that are not equipped with a factory
hood pin, or if not supported in data
[2] Key Wrap: Refer to the Immobilizer Interface section for more information about the Key Wrap.
