hi , how do you use 4 wheel drive ? sometime i was drove long distance and go up to hill on freeway 5n , i just put the button 4 wheel drive on and off when go down , it this way is ok, or somehow , can someone teach thanks

Your GX470 is in 4WD all the time, no need to push any button. That button you push for locking all wheel with the same amount of power. You should only use that if there is alot of snow on road, otherwise, you can damage the 4WD system.
