4HI if you have to. 4LO should only be for very bad conditions where you could be stuck. If you can get by using only 2wd then do that. The least you use the 4WD the better, but it sure is very helpful when you need it.
2 high, is 2 wheel drive which is where you should be when driving on the highway.2 high, is 2 wheel drive which is where you should be when driving on the highway.
Commonly, vehicles with four-wheel drive have two ranges: high and low. Low range is better for towing or accelerating quickly, but with limited top speed. High range is the opposite (better for highway driving, around town, etc.)
I'm guessing here you're speaking of the 4x4 button? If so, you don't want the button engaged on the freeway. You want the vehicle in 2 wheel drive high range.
A missing lug nut can be quite dangerous for anyone who is driving. This means that the wheel is not as tight as it should be and it can come off especially when one is driving at high speeds.
well if youre driving at high speed (80+) then you should look as far ahead as possible without losing focus on the road in front of you. If youre going normal driving speeds then about a quarter mile will do
If by this you mean only "hot heat" when drive at highway speeds likely thermostat bad and/or almost stuck and takes long time warm up from high engine RPM during highway driving.
The transmission should be in drive. The 4x4 shifter should be put in 4 high for highway use. If its push button 4x4 then use 4 high. 4 low is for pulling loads a real short distance only.
You should use low beams when driving in fog. It is more difficult to see driving with high beams in fog.
Yes, You can only shift it into 4 high while driving. You can not shift to 4 low while moving.
Look to the opposite corner of the road but keep your steering wheel straight, so as to not veer in the direction you're staring. If they're driving with highs on, flash your high beams to indicate they should turn them off.
Low is for getting unstuck with a top speed of 20 mph or so. High is for normal driving speeds.
If you are on the highway...or anywhere where speeds exceed 50-55 mph then you should have it on, otherwise it doesnt matter...even if it is on, it wont be used until you hit a high enough speed.
