4x4 PSA: Use it or lose it monthly reminder

I just got my 07 sr5 4Runner and I'm not sure how to engage the 4lo it beeps and flashes on the dash. Can someone explain the steps going from 2 wheel to 4h and 4 lo

Turn the knob from 2hi to 4 hi in drive any speed up to 60mph.

From dead stop, go into neutral, 4hi to 4 low, wait for it to engage, then go into drive.

If it beeps at you for any operation, then it failed. Restart. If it keeps beeping no matter what, then you probably got a busted transfer case actuator. Expensive fix.

Got my 4 Runner 2.5 months ago and I've gone ~30 miles offroad in hi/lo with the diff locked. It's getting exercised :)

Subbed for the reminders :D
 
Just exercised my 4Hi and 4Low around the parking lot at the train station.

I put the monthly reminder in my phone and since doing this once a month, shifting from 2H to 4H has been very quick (~ 5 seconds) and even faster into 4low.

If you haven't changed out your fluid, I would do that. After changing my fluid out in my diffs, the shifting was much faster, which got quicker the more I exercised it using this reminder.

Thanks again for the great thread!

Stupid paper

I'd be out giving it a chance to stretch it's little stock legs out, but I'm stuck writing a 1000 word paper...

Maybe next week?

I suppose it's just as well to run the actuator on pavement as long as I don't lock the center diff...
 
Great reminder. Didn't check the 4LO on the SR5 when I bought recently, but it went into H4 easily enough. Couldn't get 4LO to engage at all, kept flashing, so as I drove around I kept engaging and disengaging H4, driving for 10 miles, etc. tonight I drove home in H4 and when I tried to engage 4LO it worked just fine. I'll keep it exercised thanks to this reminder.

You can lock it on pavement if you are going in a straight line. Even if you have to turn some it's no big deal. I usually just switch it on and then off when there's a straight stretch of road, and I don't worry about driving any specific number of miles with it locked.
 
Question. Trying to get into 4LO, per the manual:

If the “4LO” (low speed four- wheel drive)
indicator light continues to blink when you
operate the four- wheel drive control
switch knob to the “H4” or “L4” position,
drive forward or backward in a short distance,
then stop the vehicle completely,
shift the automatic transmission selector
lever securely into “N” and operate the
switch knob again.

I assume this means "drive forward or backward in a short distance" while leaving the knob in the L4 position, without first switching it back to H4. This results in an audible signal which continues to sound until switching the knob back into H4 and starting the process again. Is this correct?
 
One Winter I could get mine into 4Hi, but not 4Lo, it took the warmer months to finally work. (as if you really need it in summer).

I take it to mean that if in H4, and it won't engage in 4LO, (flashing and beeping), switch back to H4, drive forward or backward a bit, depress brake pedal to a stop, shift to N and try to engage 4LO again.
