The best part of it all is, you can switch 4WD modes between 2H and 4H and while driving without any risks of speeds below 60mph/100km/h. You could drive it in 2H with only the rear wheels propelling the vehicle forward or when traction gets a bit “iffy” you just pop it into 4H – no problem at all.
What is the difference between 4X4 auto and 4X4 high?
4×4 High works by the power supplied to the front and rear wheels at the same time whereas 4×4 auto automatically navigates power to all four wheels while varying the ratio between front and back axles to what’s needed. 4X4 auto can be left on at all times while 4×4 high should not be left on.
Can you switch from 4WD to 2WD while driving?

4WD can be dangerous
If you drive faster than conditions allow, you’re far more likely to flip and roll because of your higher center of gravity. 4WD doesn’t help you brake better or give you more stability in turns while braking. So slow down when you’re turning and brake sooner.
Should you use 4 wheel drive ice?
4 wheel drive should be engaged as soon as you start losing traction on the road surface. 4 wheel drive systems send power to all 4 wheels aiding in maintaining traction while driving on slippery surfaces such as ice. … Winter tires with chains on a 4 wheel drive will offer improved traction on icy roads.
Does Auto 4WD use more gas?
A 4-wheel drive will use more gas since it has more drivetrain components and weight compared to a 2WD of the same make and model. 4 wheel drives have additional components such as an extra differential, transfer case, and an extra driveshaft.
