PLEASE READ THE COMPLETE MANUAL CAREFULLY BEFORE USING THIS PRODUCT.

We explicitly point out that all functions of this control unit should be used only while exercising caution and responsibility. We can NOT be held liable for any damage or injury caused by installing or using this product. Operation must be supervised and paid attention to in order to ensure that there are no objects or persons in range of moving parts due to the fact that top mechanics do not have pinch protection. Please study and be aware of the procedures to interrupt an ongoing operation in an emergency.

Important Information. READ BEFORE USING!

	This module comes with our USB Field Upgrade and Configuration Port! We recommend connecting it to a computer BEFORE YOU INSTALL and using our support app "m4cconnect" to do a quick firmware update check. M4cconnect as well as all other information regarding USB update and configuration can be found at www.mods4cars.com/usb. You can even configure and activate your favorite module functions and settings on screen before the module is installed in the car! It is a good idea to permanently install the USB cable with the module in the car, leaving the computer plug in an easily accessible spot for later use with a Wifi/3G/4G connected laptop.

Detailed function description (Factory setting underlined)

Function 1 - MODULE MODE + MASTER SWITCH ( 0=OFF / 1=ON / 2=EXT / 3=EXP )
The module can quickly and easily be enabled and disabled using this function. It acts like a master switch. When disabled, the module becomes completely inactive and behaves as if it was not installed while keeping all other function settings intact for when it is re-enabled later. • Setting 1 is the regular operation mode with emphasis on safety. Turning the ignition on or off as well as hitting any button on the remote at any time during remote operation immediately stops an ongoing top operation. • Setting 2 is the extended operation mode with emphasis on convenience. Starting or stopping the engine will not stop a top operation and it is possible to lock or unlock the doors one time from the remote while the top is moving. • Setting 3 is the operation mode designed for responsible experts. It allows the doors to be locked and unlocked more than once. This can come in handy if after getting out and locking the doors something was forgotten in the car and needs to be retrieved while the top is still running. Settings 2 and 3 require extra responsibility and caution to avoid injury by moving top parts to passengers not expecting the top to continue running after the engine is turned off and due to the fact that the first key press on the remote to lock or unlock the doors (or continued toggling of the door locks) will not stop the top! To abort the operation, press unlock while the doors are unlocked or lock while they are locked. EXTREMELY IMPORTANT: In order to avoid problems with diagnostic tools and to avoid confusion or risk of injury by unexpected top movement, we urge you to ALWAYS DISABLE the module before taking the car in for routine maintenance or lending it to a third person! In case of any top malfunction NEVER take the car with the module still installed to an unsuspecting dealer! In such cases ALWAYS contact Mods4Cars for support first at www.mods4cars.com or completely uninstall the module before a dealer visit.

Programming
	This module offers several different functions, each with several settings. All functions and settings are described in detail above and a quick reference table (matrix) can be found at the end of this manual. We recommend printing the matrix and storing it in the glove box! To activate the programming mode, turn the ignition fully ON (no need to start the engine), then hold down the convertible top switch (1) in the direction the top is already in (open when the top is open, close when the top is closed) until both blinker arrows in the cluster light up. Now let go. The module shows the current function via the left arrow (2) and that function's setting via right arrow (3). As an example, the left arrow blinks 1x and the right arrow blinks 2x: Function 1 is currently set to setting 2. To select the function, tap the top switch briefly. To change the setting of the selected function, hold the switch for about 1 sec. A brief tap on the top open switch advances to the next function, a brief tap on the top close switch returns to the last one. After reading the current function and setting via the blinker signals, a long tap on the top open switch increases the setting while a long tap on the top close switch decreases it. To end programming mode, either turn the ignition off or hold down the top switch in either direction for a longer time (about 5 sec) until both arrows light up. Programming mode also terminates automatically after 60 sec. of inactivity. • Shortcut to toggle Main Switch: With the ignition on as above, hold and keep the top switch pressed in the direction the top is already in (ignoring the first blinker signal) for a full 10 seconds, until the left arrow blinks once by itself. The right arrow will then indicate the Function 1 (Main Switch) setting (no blinks=OFF, 1x=ON, 2x=EXT, 3x=EXP). • Shortcut to toggle Valet Mode: With the ignition on as above and the top closed, tap the top-close switch quickly 10 times in a row, until the left arrow blinks twice by itself. The right arrow will then indicate the Function 2 (One Touch) setting (no blinks=OFF, 1x=ON, 2x=VALET).
	Programming steps on the Camaro are identical to those on the Corvette.
