4Hi Noob

Should happen pretty much right away, just make sure to engage it under the max speed limit (not sure what it is for 3rd gens, probably around 55mph). I've never had to roll more than a few feet to get it to engage/disengage on my truck.

 

Don't turn sharp corners. Go find a fairly straight road and get a mile or two in at a time. No big deal.

 

I’m the actual asshole who will read the whole Owners Manual so I’ll dig in it and find out the max speeds.

 

Always better to read it than to not

 

I haven’t had a new truck in almost 20 years. I had no idea what buttons did what. So I had to read the whole thing. Lol

 

That is just the maximum speed the computer will allow the truck to switch between 2HI and 4HI, there is no speed limit while in 4HI.

 

What just the 700 pages of the owner's manual or also the other God knows how many pages of all the other manuals for nav, entune, etc. I need to read that shit I guess.

 

Oh I read all the books. Alllll the pages. The most help I needed was with the radio and how to change the settings.

 

Ok so tell me is the parking assist supposed to beep when you're about to hit your garage door or does it only work in reverse? lol

 

Um yes there is..... it will start beeping is ass off at you above the speed.

HEY lets not forget 4low that need a little love also or the solenoids won't work when you need it..

Anyone bother pulling down the visor and read what is says ? look up ..

 

It has sensors in the rear from the book but it supposedly can detect front and rear somehow from what I’ve read. I do remember a section saying if both front and rear are detected it changes the buzzer sound. I didn’t really pay too much attention to it because I don’t have the sensors. Something I wish I would have gotten but I didn’t know it was an option.

Four-wheel drive system Summary of functions

Use the front-wheel drive control switch to select the following transfer modes:

1. 1 “2WD” (high speed position, two-wheel drive)Use this for normal driving on dry hard-surfaced roads. This position
   
   gives greater economy, quietest ride and least wear.
   
   
2. 2 “4H” (high speed position, four-wheel drive)
   
   Use this for driving only on tracks that permit the tires slide, like off-road, icy or snow-covered roads. This position provides greater traction than two-wheel drive.
   
   The four-wheel drive indicator will come on.
   
   
3. 3 “4L” (low speed position, four-wheel drive)
   
   Use this for maximum power and traction. Use “4L” for climbing or descending steep hills, off-road driving, and hard pulling in sand, mud or deep snow.
   
   The four-wheel drive and “4LO” indicator will come on.

Shifting between “2WD” and “4H”

■ Shifting from “2WD” to “4H”

1. 1 Reduce vehicle speed to less than 62 mph (100 km/h).
   
   
2. 2 Turn the front-wheel drive control switch to “4H”.
   
   The four-wheel drive indicator will come on.

■ Shifting from “4H” to “2WD”

Turn the front-wheel drive control switch to “2WD”.
This can be done at any speed. You need not depress the clutch pedal. (manual transmission only)

The four-wheel drive indicator will go off.

Shifting between “4H” and “4L”

■ Shifting from “4H” to “4L”

Automatic transmission

1. 1 Stop the vehicle completely and continue to depress the brake pedal.
   
   
2. 2 Shift the shift lever to N.
   
   
3. 3 Push and turn the front-wheel drive control switch to “4L”.
   
   The “4LO” indicator will come on.
   If the four-wheel drive indicator flashes and the buzzer sounds, try the above steps again.

Manual transmission

1. 1 Stop the vehicle or reduce your speed to less than 2 mph (3 km/h).
   
   
2. 2 Depress and hold the clutch pedal.
   
   
3. 3 Push and turn the front-wheel drive control switch to “4L”.
   
   The “4LO” indicator will come on.
   If the four-wheel drive indicator flashes and the buzzer sounds, try the above steps again.

■ If the four-wheel drive indicator light or the “4LO” indicator light blinks ●Shifting from “2WD” to “4H”

• If the four-wheel drive indicator continues to blink, drive straight ahead while accelerating or decelerating.
  
  
• If the four-wheel drive indicator continues to blink and the buzzer sounds, stop the vehicle or reduce the vehicle speed to less than 62 mph (100 km/h). Operate the switch again.
  
  ●Shifting from “4H” to “2WD”
  
  If the four-wheel drive indicator continues to blink, drive straight ahead while accelerating or decelerating, or drive forward or backward in a short distance.

●Shifting to “4H” or “4L”

Automatic transmission

If the “4LO” indicator continues to blink when you operate the front-wheel drive control switch to the “4H” or “4L” position, drive forward or backward in a short distance, then stop the vehicle completely, shift the shift lever securely to N and operate the switch again.

Manual transmission

If the “4LO” indicator continues to blink when you operate the front-wheel drive control switch to the “4H” or “4L” position, drive forward or backward in a short distance, then stop the vehicle completely, depress the clutch pedal and operate the switch again.

If the indicator light continues to blink even if doing so, contact your Toyota dealer as soon as possible. There may be a trouble in the four-wheel drive system.

■ Shifting to “4L”VSC is automatically turned off.

■ Four-wheel drive usage frequency

You should drive in four-wheel drive for at least 10 miles (16 km) each month. This will assure that the front drive components are lubricated.

WARNING

■ Caution while driving

●Never shift the front-wheel drive control switch from “2WD” to “4H” if the wheels are slipping.
Stop the slipping or spinning before shifting.

●For normal driving on dry and hard surface roads, use “2WD” position. Driving on dry and hard surface roads in “4H” or “4L” position may cause drive component oil leakage, seizure, or other problems resulting in an accident. Further, it may cause tire wear and increased fuel consumption.

●Avoid turning suddenly in “4H” or “4L” position. If you do turn suddenly, the difference in turning speeds between the front and rear wheels may have a similar effect to braking, thus making driving difficult.

●Do not shift the front-wheel drive control switch when the vehicle is turning or when its wheels are spinning freely off the ground.


Just download the PDF owner manual its very fast to look thing up..

 

It beeps if you try to switch between 2HI and 4HI, there is no speed limit or beeping if you are in 4HI above the max engagement speeds.
