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 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.
