Top speed in 4-High

[nimby]

You can hit the lever/button at any speed, it won't engage until you reduce speed to the programmed threshold.

I knew I was going to need it for an impending emergency, I saw an oncoming pickup crossing median at me in the snow. Even though I was running 65mph in the mostly clear tracks, any maneuver to avoid the collision was going to put me in a bad situation. I expected to spin out and roll over going down the opposite shoulder trying dodge him rather than take the head on. Knowing anything more than light braking in slick conditions was only going to make things worse, I did what I could. I yanked the lever to 4Hi, let off the throttle, steered over as far as I could and started fishtailing. The 4WD icon stayed flashing until the truck was below 50mph, then went solid and became more stable while still decelerating. The oncoming truck regained control on the left shoulder of my recently vacated lane, throwing a roostertail of snow at me. I recovered the fishtailing with some gentle counter-steering and slight throttle (only enough to maintain speed). Once the adrenaline rush was over, I decided to leave it in 4WD and hold less speed, as this was only the first of 3 cars I saw spin out in the same 1mi stretch.

Crazy situation and nice recovery :clap2:

I've found recently that the electronic disconnect won't lock unless I slow down to under 30 or so. The dealership replaced it along with an ABS sensor not too long ago - I wonder if they messed something up. That said, I agree with everyone else that once it's engaged you can go as fast as you like in a straight line

You had good eyes and a quicker reaction time than most would have for sure. What mfg of cameras do you use for front and back and power sources?

The movement to the other lane was delayed because I had to check my blindspot first. Watching the footage, if he didn't regain control I'm not sure I would have avoided the collision.
The camera is a Panorama X2. The front cam is wired with an add-a-fuse, with the wire in the headliner and down the pillar. The rear camera has a cable that runs to the front one tucked above the headliner.
