When it comes to driving in snowy conditions, having a 4-wheel drive (4WD) vehicle can make all the difference. But when should you use 4WD high or 4WD low? Many drivers are unsure of which setting to use, and the decision can impact their safety on the road. In this article, we will explore the differences between 4WD high and 4WD low and give you some tips on when to use each setting.
What is 4WD High?
4WD high is a setting that is designed for driving on slippery or uneven surfaces. It is ideal for driving in snow, mud, or sand, as it provides better traction and stability. 4WD high distributes power evenly to all four wheels, which means that the wheels can spin at different speeds without losing control. This setting is also useful for driving on steep hills or rocky terrain, as it provides more torque and power to the wheels.
However, it is important to note that 4WD high is not designed for driving at high speeds on dry roads. Using this setting on dry roads can cause unnecessary wear and tear on your vehicle's drivetrain and decrease fuel efficiency.
What is 4WD Low?
4WD low is a setting that provides maximum torque and power to your vehicle's wheels. It is designed for driving at low speeds on extremely slippery or uneven surfaces, such as deep snow, mud, or sand. 4WD low gives you the ability to crawl over obstacles and steep inclines without slipping or losing traction. This setting is also useful for towing heavy loads, as it provides more pulling power.
However, 4WD low is not designed for driving at high speeds. Using this setting on dry roads can cause your vehicle to overheat and damage your drivetrain. It is important to only use 4WD low when necessary and switch back to 4WD high or 2WD when driving on dry roads.
When to Use 4WD High or Low?
So, when should you use 4WD high or low when driving in snowy conditions? The answer depends on the severity of the snow and the type of terrain you are driving on.
4WD High
If the snow is less than six inches deep and the roads are plowed, you can use 4WD high. This setting is also ideal for driving on flat or slightly inclined surfaces. However, if the snow is deeper than six inches or the road is steep, switch to 4WD low to avoid getting stuck or losing traction.
4WD Low
If the snow is deeper than six inches or the road is steep, use 4WD low. This setting provides maximum traction and power to your wheels, which is essential for driving in deep snow or on steep inclines. However, it is important to remember to switch back to 4WD high or 2WD when driving on dry roads or when the snow has been cleared.
Tips for Driving in Snowy Conditions
Regardless of whether you are using 4WD high or low, there are some tips you should keep in mind when driving in snowy conditions:
1. Reduce Your Speed
Driving in snow requires you to reduce your speed and give yourself more time to stop. This is especially important when driving down hills or around curves.
2. Increase Following Distance
Leave more space between you and the vehicle in front of you to allow for more stopping distance in case of an emergency.
3. Avoid Sudden Movements
Avoid sudden movements, such as hard braking or sharp turns, as this can cause your vehicle to slide or lose control.
4. Use Winter Tires
Winter tires provide better traction on snowy or icy roads and can improve your vehicle's handling in winter conditions.
Conclusion
When driving in snowy conditions, it's important to know when to use 4WD high or low. 4WD high is ideal for driving on flat or slightly inclined surfaces, while 4WD low is designed for driving in deep snow or on steep inclines. Remember to switch back to 4WD high or 2WD when driving on dry roads or when the snow has been cleared. By following these tips and using the appropriate 4WD setting, you can stay safe on the road during winter conditions.
