When to use high range vs. Popular Mechanics notes high range is for higher speeds and less traction than 4WD low. Edmunds recommends using 4WD high range on dirt or paved roads that are snowy, slick or icy.
Edmunds says 4WD low range is for off-roading conditions, like deep sand, where you need serious traction. Unlike 4WD high, adds Motor Authority , the low setting turns the wheels slowly but gives you more torque on less forgiving terrain.
Do not use 4WD on flat, smooth and dry roads, as it can damage your vehicle, according to Consumer Reports. Family Handyman adds that 4WD uses up more fuel to get the gears and drive shaft going. Turn it off when you don't need it to save on gas. According to Cars. It's typically used for lighter-duty vehicles such as sedans or car-based SUVs.
An AWD engine can also regulate how much power is being sent to the front and back tires. This helps the car get the best possible traction. You also need to consider the specific type of car you have and the condition of your tires. On top of knowing how to use 4WD, make sure you have the right insurance to cover the vehicle itself. Important note: before you go off-road, set your traction control, which likely means disabling it.
The button usually has some squiggly lines on it. That's your stability-control-defeat button. Stability control will try to keep your tires from spinning. If you're on a rocky trail, that can be great—by grabbing the brakes at individual corners, stability control can sometimes mimic the benefits of locking differentials.
We proved that with the Kia Telluride. But if you're in mud, sand, or snow, stability control might get you stuck, even if you've got four-wheel drive. That's because in certain circumstances, you want wheelspin and momentum. Out on the sand, your stability control system will detect wheelspin and cut power to the spinning wheels. Which, in that context, will be all of them. Then you grind to a halt. To turn off the system, you usually hold down the button for at least five seconds.
First the, traction-control system will deactivate sometimes just with a push of a button but you want the whole thing off, so hold down the button until you see a message like "stability-control system disabled.
One more thing: the price of your 4x4 often has a direct correlation to the complexity of its drive systems. And we can't really explain all of them on a case-by-case basis, but if you purchase a machine with overt off-road pretensions, it behooves you to study up on its capabilities.
A Mercedes GLE with the optional hydropneumatic suspension can bounce itself out if it gets stuck. The Ford Raptor offers something called Baja mode, which activates an antilag system for the turbos—yee haw.
Difficult terrain could be any of the following:. This makes stalling more difficult in 4 Lo. Low-range or 4-Lo is a very powerful function of a 4WD and allows you to accomplish feats no 2WD ever could. You engage low-range to get you through soft sand , over tall sand dunes, up steep hills, and down difficult mountain tracks. Use it wisely and your 4WD will, not only take you to many amazing places but also bring you back home safely.
This allows for more controlled handling without placing all the stress on the brakes alone. As mentioned earlier, 4-Lo is used only when you require optimal traction and absolute maximum power. This is only to be engaged when the terrain is really difficult and driving conditions forces you to lower your speed and gear selection down to 1st or 2nd gear. Extreme rock crawling when you need to negotiate each obstacle slowly and precisely will call for 4-Lo.
When doing any deep river crossings you are better off engaging 4-lo to ensure you are getting optimum traction and using the power available to you sufficiently.

Each and every off-road situation or obstacle needs to be carefully calculated and assessed by you before you decide to take it on.
However, a good rule of thumb is always to judge the speed vs the difficulty you are required to succeed. Generally, if you cannot engage 4-Hi 2nd or 3rd gear to cross an obstacle or if you feel the obstacle will place too much mechanical stress on your vehicle then you are better off engaging 4-lo and rather take it slow and steady.
Always ensure you keep the risk of vehicle damage to an absolute minimum. This will mean you will at times have to exit your vehicle and walk the terrain or the obstacle first to determine the best driving line and if there is any risk of stalling or if a roll-back or even a rollover is a possibility.
