What is 4H mode on Ford Expedition?
The Ford Expedition is a popular full-size SUV known for its impressive off-road capabilities. One of the key features that enhances the Expedition's performance in challenging terrain is the 4H mode, which stands for "Four-High." This mode is designed to provide additional traction and control when driving on slippery or uneven surfaces, such as mud, sand, or snow.
What is 4H Mode?
The 4H mode on the Ford Expedition is a four-wheel-drive (4WD) setting that engages the vehicle's transfer case to distribute power evenly to all four wheels. This helps to improve traction and stability, especially in situations where the terrain is unpredictable or requires more control than a standard two-wheel-drive (2WD) setup can provide.
When the 4H mode is engaged, the Expedition's powertrain is configured to deliver power to all four wheels simultaneously, rather than just the rear wheels or the front wheels. This results in improved grip and better handling, which can be particularly useful when navigating through mud, snow, or other slippery conditions.
When to Use 4H Mode
The 4H mode on the Ford Expedition is typically recommended for use in the following situations:
- Driving on unpaved roads or trails with loose or uneven surfaces
- Navigating through deep snow or mud
- Climbing steep hills or inclines
- Towing heavy loads or trailers
- Traversing rocky or uneven terrain
It's important to note that the 4H mode should not be used on dry, paved roads, as it can cause excessive tire wear and decreased fuel efficiency. The Expedition's 4WD system is designed to be used primarily in off-road or low-traction situations, and engaging the 4H mode on smooth, dry surfaces can lead to premature wear and tear on the vehicle's components.
How to Engage 4H Mode
Engaging the 4H mode on the Ford Expedition is typically a straightforward process. The vehicle's transfer case will have a selector switch or dial that allows the driver to choose between 2WD, 4H, and 4L (Four-Low) modes. To activate the 4H mode, simply turn the selector to the "4H" position while the vehicle is in motion, typically at speeds below 55 mph.
It's important to note that the 4H mode should only be engaged when the vehicle is on a suitable surface, such as dirt, gravel, or snow. Attempting to engage the 4H mode on a paved road can cause damage to the vehicle's drivetrain and should be avoided.
By understanding the purpose and proper use of the 4H mode on the Ford Expedition, drivers can take full advantage of the vehicle's off-road capabilities and ensure a safe and enjoyable driving experience, even in challenging terrain.
Does 4H make you go faster?
Automakers recommend keeping 4H at 55 mph or less, but it can go faster than 4L. In rough roads, 4H provides better acceleration because more power is transferred to the wheels. When driving on paved or smooth roads, it also improves fuel efficiency.
Is 4H good for icy roads?
4H is the way to go for snowy, icy, muddy, or rocky surfaces, providing better traction and stability. It is also great for moderate off-road conditions with some obstacles or inclines. On the other hand, 4L is intended for extreme off-road conditions such as steep inclines, coarse terrain, and deep mud.
When should I shift to 4H?
For slippery conditions and light off-road driving, you may need to shift into 4-wheel high or 4H for added traction. To do that, first slow down to less than 62 miles per hour, then turn the knob to 4H.
What does 4H mean on Ford Expedition?
4H (4X4 HIGH) Provides mechanically locked four-wheel drive power to both the front and rear wheels for use in off-road or winter conditions such as deep snow, sand or mud. This mode is not for use on dry pavement. Note: 4H may engage or disengage automatically based on terrain mode selection.
What drive mode should my Expedition be in?
The drive modes include Normal for around-town driving, Sport for more spirited trips, Tow/Haul for improved towing and hauling performance, Eco, Grass/Gravel/Snow for loose terrain, Sand for low-traction situations, and Mud/Ruts for uneven surfaces.
Can you drive in 4 high all the time?
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.
What drive mode is best for gas?
Eco mode puts less strain on a car's engine, resulting in several benefits such as: Improved fuel economy: While the change in fuel economy isn't drastic, your car will use less gas and get more miles per gallon when you use eco mode correctly.
Should I use 4A or 4H in snow?
So, use 4a in rain, snow, slippery conditions on pavement. Use 4H off-road, never on pavement, in like deep snow, sand or gravel where the wheels can spin easier and not bind up on pavement.
Should I drive my Expedition in 2H or 4A?
Two-Wheel Drive High (2H): Best used for general on-road driving. Power is sent to the rear wheels only. Four-wheel drive auto (4A) (if equipped): Electronically controlled 4WD with power delivered to the front and rear wheels. Provides increased traction on varied road conditions.
Is it OK to drive in 4H?
4H provides electronically locked four-wheel drive power to front and rear wheels. The information display will display 4H when this mode is selected. This mode is not recommended for use on dry pavement. This mode is only intended for severe winter or off-road conditions, such as deep snow, ice or shallow sand.
