If you made any changes in the setup menu, be sure to scroll to “full reboot?” and
“select” it. This step is critical after changing settings, or you may nd that the dash
doesn’t shut down, which can result in a dead battery.
Vehicle Settings
This section explains how to use the Tazer JL Mini to change the
vehicle settings for feature activation.
Menu Navigation
• For all functions involving the dash
(EVIC) display, the EVIC screen rst
needs to be in a state where it’s
showing the AUDIO screen. Use the left
and up/down arrows to set the EVIC
display like this. One the display is in
this state, press and hold the steering
wheel LEFT ARROW, and tap the Cruise
“CANCEL” button to enter the settings
menu. Pressing LEFT ARROW and
CANCEL will advance through the menu
items. To change/select a setting,
press and hold LEFT ARROW and tap
the Cruise “ON/OFF” (center) button.
• Advance through the menu slowly.
• You can exit the menu quickly and
safely by holding the left arrow and
pressing the cruise RES button.
• If the text is overwritten by another
message, press the left arrow and the
display will revert back to the Audio
display.
Some settings require two sleep/wake cycles. The quickest way to do this is to turn
the ignition off, leave the car, close the driver’s door and walk away with the key. Wait
about 60 seconds AFTER the dash goes dark, then re-enter. Do this twice.
Exit the menu quickly and safely by HOLDING the LEFT ARROW and TAPPING the
Cruise “RES” button.

After unmarrying, advance to the “full
reboot?” option and select it, allowing a
full 2.5 minutes for the Tazer JL Mini to
reboot all systems – the Uconnect will
reboot twice in this time, the dash will
reset, and when it’s nished, the red
security dot on the dash will turn on and
back off. A few sleep cycles might be
required for all changes to take effect.
