Car and Driver notes that 4WD is not meant to be used all the time. It's only for certain road types, including rugged terrain and off-roading, as well as slippery conditions, like snow or mud. Otherwise, 4WD vehicles should be driven in two-wheel drive, according to Car and Driver.
When should I use 4x4 auto?
Because the front and rear axles need to spin at different speeds on the road, you should activate 4WD only when your tires leave the pavement. That might be turning onto a dirt road or entering consistently snowy conditions, where the road surface is completely covered.Jun 19, 2018
What is 4x4 auto?
A 4x4 car or truck, additionally called 4x4 (4WD) or 4-by-4, means a system in which a vehicle's engine powers all 4 wheels evenly. Typically speaking, when it concerns cars and trucks, there are only four options: four-wheel drive, all-wheel drive, front-wheel drive, rear-wheel drive.
What happens if you drive fast in 4 high?
As mentioned above, driving in high-speed with 4WD on means your wheels on both sides of the truck or car always turn at the same speed. That's fine if you're driving straight ahead, but any turn of the wheel to the sides at high speeds could be extremely dangerous.May 19, 2018

Yes. 4wd high when there is no dry spots, like a snow storm or heavy heavy rain. 4wd auto can be used daily no matter the conditions. 4wd low only when you are offroad, or need maximum pulling power, but not much turning.Aug 7, 2019
Should you drive your truck in Auto?
While every truck maker acknowledges using 2Hi is the best setting for fuel economy, the peace of mind of having the truck always in 4WD Auto is a big win for a lot of truck owners. In fact, quite often, owners tell us they always drive around with 4WD Auto since you never know when you might need the extra traction.Nov 5, 2021
What is the difference between 4x4 Auto and 4x4 high?
Without an Auto setting, 4WD High is what you'd use in any situation that's low-traction but relatively high-speed—a dirt road or snowy paved road. 4WD Low is strictly for slow off-roading or places where torque multiplication would really help you out (like deep sand).Nov 16, 2021
FAQs
On dry pavement or tarmac, you shouldn’t tow your trailer in 4WD. 2WD is enough for relatively flat surfaces. It would be best if you changed to 4-wheel drive only under extreme conditions like muddy or snow-covered roads where extra traction is needed.
Final Thoughts
Speed is of paramount importance when driving in 4WD. The maximum speed you should use in 4-High is 55mph and 10mph in 4-Low. However, these maximum speed values are dependent on the type of vehicle and model too.
How fast can you drive in 4WD?

What happens when you drive a 4WD high?
When your vehicle is in 4WD-High, the engine power is sent to both front and rear axles. This is, in turn, split 50/50 between each wheel on that axle, which means each wheel receives 25% of the engines total power.
What does it mean when a 4WD is low?
If you are driving fast on a low traction surface the handling of a 4WD or any vehicle is drastically reduced. The steering is no longer crisp and direct. If you feel the vehicle not responding well while turning, In most cases it means traction is low, hence the understeering effect. A 4WD can easily drift in a corner when surface traction is low, ...
What are the elements that affect 4WD?
Elements like cornering, braking and acceleration are all negatively affected and we need to be aware and prepared for that. When cornering in 4WD on a slippery surface we want to avoid sudden braking and aggressive cornering. The vehicle can easily lose traction and veer off the road, resulting in an accident.
How much does stopping distance increase on a low traction surface?
The stopping distance on a low traction surface can increase by as much as double (2x) that of regular braking distances, such as on a tarmac surface. The 3 key elements that make up the braking distance are the following: Traction. Reaction time. Stopping time.
When you engage 4WD Hi, should you always be on a low traction surface?
With that being said, a low traction surface could be a dirt road, a muddy track or a slippery snow highway.
What are the challenges of 4WD?
When in 4-Lo mode the 4WD can more easily drive on challenging terrain without placing strain on the gearbox, clutch, and engine. Challenging terrain could be: 1 Loose deep beach sand 2 Thick mud 3 Rock crawling 4 Steep uneven low-traction Inclines 5 Long technical declines 6 Deep River crossings.
How fast can you drive in 4H?
A general rule of thumb is, no faster than 60mph when in 4H.
When to leave 4WD on Ram?
Most Ram owners leave their trucks in 4WD Auto during the winter months when there is constant snow and ice on the roads . The 4WD Auto function will calculate when traction is low and send power to the inside wheels when cornering, thus offering greater stability.
What happens when traction is lost on the rear wheels?
However, when traction is lost on the rear wheels, the front axle is immediately engaged for improved traction and stability and the drivetrain automatically engages 4H. Once the vehicle senses traction has been regained in the rear wheels, it disengages the front and the truck reverts back to 2H mode.
What is 4H on a car?
4H is when the center diff is locked and the engine power is split between the front and rear axles. In 4H the front wheels will pull the vehicle forward while the rear wheels propels the vehicle simultaneously. 4H is only means to be used on slippery low traction surfaces such as sand, dirt roads, mud and snow.
Is 4WD auto more sophisticated?

Does anyone do this all the time? I noticed the truck is a little quicker to respond to the throttle. Anyone else notice this or do this?
MNDaveC
No, I put mine to 2wd only , but I'll probably use auto in the winter.
dodgehemi0
It's auto only goes into 4x4 when the truck thinks you need it. It turns just like it did in 2wd. No binding it should not be in 4x4 going down the road.

I was under the impression that 4auto locks the front axle, but leaves the tcase in 2wheel. There is a clutch in the tcase that can engage in an instant if the wheel speed sensors detect slip. This saves the delay required to engage the front axle.
fondupot
Good to know. I figured something had to be different with the information given on here. Completely different transfer cases I assume?
Can you go as fast as you want?
In general, as fast as you want. However, your local laws have a word in that as well. Not only the posted speed limit will need to be observed - depending on the weather conditions the law might might keep you from even getting to the speed limit.
Should I use 4WD on slippery roads?
Owners of part time 4WD systems (the ones that let you chose between 2WD and 4WD) should be very cautious when using 4WD on slippery roads, because their handling is not as precise as full time 4WD and AWD. For one, they should always shift back to 2WD when approaching dry surfaces (and back to 4WD on slippery stuff) because part time 4WD should ...
Is 4WD better than AWD?
4WD and AWD makes driving on lower traction surfaces more stable and a bit safer. But neither 4WD nor AWD plus their added stability features, like traction control and stability control, can defy the laws of physics. If you are too fast - you are too fast.
Should I shift to 2WD or 4WD?
For one, they should always shift back to 2WD when approaching dry surfaces (and back to 4WD on slippery stuff) because part time 4WD should never be used on dry surfaces. If you do, you can cause severe mechanical damage. Also, when in part time 4WD neither ABS, traction control or stability control will work.
What does 4WD auto do?
4wd auto kinda acts like a awd vehicle when auto is selected , the vehicle remains in 2wd now when the truck senses wheel slip "spinning" the front axle automatically engages . i found Auto to work well in snow or wet grass ect... it does not hurt the vehicle to drive it around town in auto#N#4wd Hi means the vehicle is locked into 4wd all 4 wheels will spin . this is best used for light mud or sand ect when you need it and IMO should not be drivin around all the time in this selection only when needed
Can you use 4LO on pavement?
4LO is ONLY to be used off of pavement...there MUST be some slippage of the wheels (gravel, wet areas, etc) or you will trash the diff when you turn (outside wheel tries to move faster than inside wheel, but diff is locked). 4HI is like 4auto but is full time, again, not to be used on dry pavement.
Is Denali 4 wheel drive?
1. Denali is full time all wheel drive and controls the 4 wheels independantly. There is no procedure shifting into or out of 4HI and can be done at any speed. If you had a 2-speed transfer case (with 4lo) that needs to be done at 3mph or less with the transmission in neutral. Sep 24, 2012.
