Your vehicle has plenty of unique features that help you navigate through different terrain, but sometimes it’s hard to understand what each component does. So what is the difference between “hill hold” and “hill assist”?
Hill assist is an automatic driver-assistance feature that prevents your vehicle from rolling backward on an incline or decline, like a hilly road, by maintaining brake pressure after you’ve taken your foot off of the brake and releasing it when you raise the clutch pedal. Hill hold, or auto-hold, automatically holds the brake pressure you applied, no matter the angle your vehicle is on, and disengages when you accelerate.
We’ll break down how these two safety features, give you the subtle difference between them and show you how to use them effectively.

What Is The Function Of “Hill Hold” And “Hill Assist”?
“Hill Hold” and “Hill Assist” are two features found in modern cars that can be incredibly useful when navigating steep inclines and declines. While they are similar in function, they are slightly different and can be used in different ways.
Hill hold is a feature that helps prevent a car from rolling backward when it is stopped on a steep incline. This feature uses the car’s brakes to hold the car in place until the driver releases the brake. Hill hold is usually activated when the driver takes their foot off the brake while stopped on a steep incline.
Hill assist, on the other hand, works in a slightly different way. Instead of using the brakes to hold the car in place, hill assist uses the car’s engine to help prevent the car from rolling backward.
It works by automatically engaging the accelerator for a brief moment to prevent the car from rolling back. This feature is especially useful when starting from a complete stop on an incline.
Both of these features are incredibly useful when navigating hilly terrain. Hill hold is best used when the car is stopped on a hill and the driver needs to take their foot off the brake for a moment.
Hill assist is great for starting from a complete stop on a hill. It helps prevent the car from rolling backward and keeps the car in place until the driver can get it moving.
Overall, hill hold and hill assist are two features that can help make driving on hilly terrain much easier. They can provide an extra level of safety and control when navigating steep inclines and declines.
What’s The Difference Between “Hill Hold” and “Hill Assist”?
Comparing “Hill Hold” and “Hill Assist”
“Hill Hold” and “Hill Assist” are two features in modern cars that aim to make driving on an incline easier. Although they serve similar purposes, they operate differently and have distinct characteristics.
The primary difference between “Hill Hold” and “Hill Assist” lies in their activation: Hill Hold requires manual engagement, while Hill Assist activates automatically when the car’s sensors detect an incline.
Activation Process
In terms of their activation process, Hill Hold is a manually activated feature. It necessitates the driver’s involvement to engage it when the vehicle is stopped on a hill.
Conversely, Hill Assist is an automatic function that kicks in whenever the car’s sensors detect that the vehicle is on an incline.
Brake Engagement Duration
Another key difference between Hill Hold and Hill Assist is the duration for which the brakes remain engaged. In the case of Hill Hold, the brakes will stay engaged indefinitely until the driver applies the accelerator.
In contrast, Hill Assist will maintain the brakes for a few seconds, giving the driver enough time to switch from the brake pedal to the accelerator.
Technological Complexity
Hill Assist generally incorporates more advanced technology than Hill Hold. It uses sensors and vehicle dynamics control systems to detect when the vehicle is on an incline and applies the brakes accordingly.
On the other hand, Hill Hold systems are typically simpler and may lack the precise incline detection capabilities that Hill Assist systems offer.
This makes Hill Assist a more sophisticated, but also more complex, system compared to Hill Hold.
User Convenience
While both systems are designed to prevent the vehicle from rolling back on an incline, their level of user convenience varies.
Some drivers might prefer the control that comes with Hill Hold, as it allows them to decide when to engage and disengage the system.
However, others may find Hill Assist more convenient, as it requires no manual intervention and activates only when needed. In other words, Hill Hold offers more control, while Hill Assist provides ease of use.
Impact on Vehicle Wear and Tear
Both Hill Hold and Hill Assist can reduce wear and tear on the vehicle’s transmission, particularly in manual cars.
By preventing the car from rolling back, they lessen the strain on the clutch as the driver switches between the brake and accelerator pedals.
But the difference lies in their activation — the automatic nature of Hill Assist ensures this protection is always in place when driving on inclines, whereas Hill Hold’s effectiveness depends on the driver remembering to engage it.
Therefore, Hill Assist might provide better overall protection against wear and tear.
How Does “Hill Assist” Work?
Hill Assist is a feature found in many modern cars that helps drivers navigate steep inclines. It is designed to make it easier to start from a stop on an incline and prevent the car from rolling backward when shifting gears.
Hill Assist works by using the car’s brakes to hold the car steady on an incline. When the driver releases the brake pedal, the car’s computer automatically applies gentle pressure to the brakes to keep the car from moving backward.
When the driver is ready to move, they can either press the accelerator pedal or shift the car into drive. If the driver presses the accelerator, the computer releases the brake pressure and allows the car to move forward without rolling back. In manual cars, the feature assists with smoother shifts from reverse to drive.
Hill Assist is especially beneficial for drivers in hilly areas. It makes it easier to start on steep inclines without worrying about the car rolling backward. Additionally, it helps new manual car drivers make smoother shifts on inclines.
Clutch detection (on manual vehicles only).
The first system detects when you push in the clutch to engage the hill assist. When your clutch is engaged, there is no braking power coming from the engine. Your vehicle can roll freely, either through acceleration from gas or from rolling on an incline. The system activates hill assist when you engage the clutch.
Incline detection.
Another sensor in the hill assist function measures the incline your vehicle is resting. If the angle is beyond a certain degree, the sensor sends a signal activating the hill assist to engage your brake.
Engine torque detection.
Another sensor monitors your vehicle’s torque, the force your engine gives out. Once your engine produces the torque required to move your vehicle forward, the hill control system will disengage. The amount of torque will change depending on the angle of your vehicle.
Brake detection.
The brakes also have a sensor that measures when the brakes are engaged and how much brake force you are applying. If there’s not enough braking power, the hill assist will turn on.
Backward / forward roll detection.
The hill assist system also detects when your vehicle is rolling backward or forward. The system will then engage the braking system so you can smoothly accelerate through hills or inclines.
The hill assist function will only hold the brakes for a few seconds after you begin releasing the brakes yourself. You’ll have to accelerate at a gradual level to make sure you’re moving your vehicle forward in time.
How To Use”Hill Assist”?
In most vehicles, the hill assist system is automatically on, so you don’t have to do anything to activate it. However, there are some vehicles that have a button on the dashboard to toggle the system on or off.
With a manual transmission, here is the process you can go through to take advantage of hill assist.
- Press the brake pedal and push in the clutch at the same time.
- Shift into 1st gear if you’re in the “Neutral” position.
- Lift your foot off the brake pedal, and slowly release the clutch while giving a little gas.
- The car will eventually disengage the brakes until you have enough power to propel it forward.
With an automatic transmission, we’ll lay out the steps of starting your vehicle on a hill or incline:
- Press the brake pedal and turn the ignition.
- Shift into the “Drive” position.
- Release the brake and step on the accelerator.
- The car should hold the brakes for a few seconds until you get the vehicle going.
How Does The “Hill Hold” Function Work?
Introduction to Hill Hold Function:
The “Hill Hold” function is an important safety feature that is now included in many modern cars. It is designed to help drivers safely navigate steep hills and prevent vehicles from rolling backward when transitioning from a stop to a start.
Comparison of Hill Hold and Hill Assist:
Hill hold, or auto hold, serves a similar function to hill assist, to automatically engage your brakes. It is a part of the ESC unit that works with the Antilock Breaking System to stop your car from rolling away accidentally. This function is much simpler than the hill assist, however.
How does the Hill Hold feature work?
The Hill Hold feature works by automatically detecting when the car is stopped on an incline. When the driver takes their foot off the brake and transitions to the accelerator, the Hill Hold feature will engage and apply a slight amount of resistance to the wheels.
This resistance prevents the car from rolling backward before the driver can build up enough torque to move forward.
Auto Hold System:
When you press the brake of your vehicle at a standstill position, the auto hold system keeps that braking pressure. In fact, you can remove your foot from the brake entirely, and the braking system will continue to work.
The auto-hold system may also increase the braking power if the ESC system detects any rolling movement. When you press the gas pedal or release the clutch in a manual vehicle, the auto hold will reduce the braking pressure for a smooth start.
Differences between Hill Hold and Hill Assist:
The auto hold function will continue to break for an unlimited time, which is a primary difference when comparing it to hill assist. Your car will remain at a standstill until you press the acceleration pedal or turn off your vehicle.
Activation and Deactivation of Hill Hold Feature:
The Hill Hold feature is typically activated automatically when the vehicle is stopped on a hill, but some cars may require the driver to press a button to activate the feature. Additionally, the driver can also deactivate the Hill Hold feature if they prefer.
Limitations of Hill Hold Feature:
It is important to note that the Hill Hold feature is not designed for use on slippery surfaces or when the car is stopped on an icy hill. In these cases, the Hill Hold feature will not engage and the driver will have to use manual techniques to prevent the car from rolling backward.
How Do You Use “Auto Hold”?
Auto Hold” is a feature that is available on many modern vehicles. It can be used to keep the car in the same position on an incline or decline, without the need for the driver to keep their foot on the brake pedal. This allows for a more relaxed driving experience, as the driver does not need to continually press the brake to keep the vehicle in place.
To use “Auto Hold”, the driver should first press the “Auto Hold” button, which is usually located on the center console. Once the button is pressed, the car will automatically engage the parking brake and hold the car in place. This feature can be disengaged by pressing the Auto Hold button again or by pressing the accelerator.
“Auto Hold” is a function that isn’t automatically on. It’s a great feature to use when in stop-start traffic, on hilly roads, or when you’re driving in general. In newer vehicles, the “AUTO HOLD” icon will illuminate your vehicle’s dashboard. Usually, enabling auto hold is an easy process:
- Press the “Auto Hold” button on the console or instrument cluster near your dashboard. It can be turned on at any time, even if your vehicle is already moving.
- Press your brake until your vehicle is completely stopped.
- Remove your foot after you’re stopped. The system will keep your car stationary until you press the gas pedal.
“Auto Hold” can be utilized when parking on inclines or declines to prevent the car from rolling back or forward. When the car is on an incline, “Auto Hold” keeps it from rolling back, while on a decline, it prevents rolling forward.
When using “Auto Hold,” it is crucial to disengage the feature before driving away. Failure to do so can result in the car continuing to brake, even when the accelerator is pressed, leading to unexpected lurching forward, which can be dangerous.
This feature is highly beneficial for driving in hilly areas as it enhances convenience and safety. Before utilizing “Auto Hold,” take the time to understand its functionality and ensure that it is disengaged before driving away.
