Many car buyers love vehicles with all-wheel drive (AWD) or 4-wheel drive (4WD). This is because they know the car will give them better control and improved performance, especially when driving in muddy or snowy conditions. However, many vehicles have an optional 4WD system, meaning the driver decides when to switch on this feature.
The vehicle usually drives on the front wheels or the rear wheels, but the driver can activate or deactivate the 4WD. Therefore, drivers need to understand when to use the 4WD to avoid making mistakes that increase gas consumption or amplify the accident risks on the road. This article will help drivers learn when to switch to the four-wheel drive.
How Does the Four-Wheel System Work?
Many modern SUVs come with AWD or 4WD features. If a car has an optional 4WD, the driver can engage this system when navigating tough or slippery terrains to improve traction and safety. However, they should disengage the 4WD once the driving conditions are favorable.
When the 4WD system is active, each wheel spins with the same force and at the same rate as the other wheels, giving the vehicle the needed boost to get out of the mud and avoid sliding or slipping. The top karl malone toyota dealers understand that some car buyers do not know how the four-wheel system works. Therefore, they have technicians and a competent sales team to guide inexperienced buyers and ensure they use this feature safely.
When to Use Four-Wheel Drive
The 4WD equips the vehicle with the stability and traction required on rugged trails and dirt roads. This is because the system distributes the power from the engine to all the wheels, increasing the chances of getting out of rocky and uneven terrain.
The four-wheel drive can be handy when driving on mud or sand, which usually makes the vehicle sink. If the 4WD is not engaged, the powered wheels will rotate faster and sink the car into the sand or mud. However, the four-wheel system distributes power and makes it easy for the vehicle to keep moving without sinking.
When using the 4WD, the front and rear axles spin at the same rate, which means that the driver should engage it on a rough road or a slippery surface for effective coordination of the front and rear wheels.
Steep slopes increase the chances of a vehicle slipping or sliding. Therefore, drivers should consider using the 4WD option when ascending or descending steep slopes. Unlike the front or rear-wheel drives, which may struggle to pull or push the weight of the entire vehicle, the four-wheel drive distributes the power and increases the grip. This feature is more important when a car is transporting heavy roads or when there is poor visibility.
In winter, roads in some states are covered with ice, which reduces the grip on time and makes the vehicle slip or slide. However, the 4WD can mitigate the risk by increasing traction and distributing power equally to all the wheels. When the wheels rotate simultaneously, the driver enjoys more control and stability.
How to Switch to Four-Wheel Drive
Some drivers have no idea how to turn on the 4WD system. Others think they know how to do it correctly but they have limited knowledge about it. This could cause an accident, especially if the driver thinks the vehicle is in 4-wheel mode while it is not.
Since the 4WD knob or lever varies from one car model to another, it is advisable to consult a mechanic or read the user manual. However, the knob or lever should rest on the section labeled 4WD in most models. The dashboard display will also show that the car is in the four-wheel drive mode.
Should the driver stop to engage the 4WD? The answer usually depends on the vehicle model and make. Old car models usually need manual engagement when the car is not moving. However, newer cars will likely have an electronic system for engaging the 4WD, which means activating the system is as easy as pressing a button.
In this case, the driver can push the button or turn the knob without stopping the car. To avoid confusion, drivers should check the user manual or consult experienced mechanics to learn how to activate and deactivate the 4WD.
When to Avoid Using the 4-Wheel Drive System
Car manufacturers design four-wheel drive systems for use in rough or slippery conditions. So using it on even and dry surfaces causes unnecessary wear and puts the driver and other road users at risk. Activating the 4WD on roads with sufficient traction could stress the drivetrain and make the vehicle lose stability, especially when negotiating corners. Additionally, using the 4WD reduces fuel efficiency and could increase transport costs.
Some drivers tend to accelerate even when the 4WD is activated. The improved traction could cause the driver to lose control when turning because the front and rear wheels move at the same speed.
Besides, using the low 4WD at high speeds could overheat the transmission system and the differential, causing damage. Even if the high 4WD supports high speeds in some cars, it is not always advisable to use it regularly on standard dry tarmac roads.
It is crucial to note that 4WD does not improve handling or braking. Therefore, drivers should maintain a uniform speed and start breaking earlier when the road is slippery or covered with ice. Overlooking this important tip could lead to a collision. This is because the 4WD system can entice the driver to drive faster thinking that the car will respond as quickly when they apply the brakes.
As explained, the 4WD increases traction and prevents slipping and sliding while driving on challenging terrains. Drivers who understand how the system works can use it appropriately to improve performance and safety on the road. Therefore, beginners should use these tips to use the four-wheel drive appropriately and avoid making mistakes that put them or other road users at risk.
