What is Auto Hold? How is it used?

The Auto Hold feature, found in many modern vehicles today, is an important driver assistance system that enhances both comfort and safety while driving. Therefore, it is important to understand what Auto Hold does, how it works, and in which situations it provides an advantage. Developed to give drivers a more comfortable experience, especially in heavy traffic and on steep inclines, this technology has become an indispensable part of modern driving assistance systems.

What is Auto Hold?

Auto Hold is a driving assistance system that keeps the vehicle stationary without the need to keep your foot on the brake pedal during stop-start situations.

The system engages when the vehicle comes to a complete stop and prevents the vehicle from moving backwards or forwards until you press the accelerator pedal. This is particularly useful in heavy traffic, on ramps, and during long stops. Auto Hold works in conjunction with the vehicle's electronic brake control systems and maintains constant brake pressure without driver intervention.

This feature enhances both comfort and safety. You enjoy a more relaxed driving experience as you no longer need to keep your foot on the brake pedal.

What Does Auto Hold Do?

Auto Hold prevents the vehicle from moving unintentionally and reduces the driver's burden on brake control.

The main advantages provided by the system are as follows:

  • It provides comfort in traffic. There is no need to keep the brake pedal pressed continuously in stop-and-go traffic.
  • Prevents rolling on slopes. The vehicle does not roll backwards when stopped on an uphill or downhill slope.
  • Improves traffic safety. The vehicle remains stationary, especially during sudden stops, and does not move if the pedal is accidentally released.
  • Reduces driver fatigue. Less pedal use during long journeys and in heavy traffic means less physical fatigue.

The Auto Hold system is a technology that provides great convenience, especially for new drivers, as it is designed for safe stopping.

Auto Hold is a brake management system that electronically maintains brake pressure when the vehicle is stationary.

The system's operating principle is based on the following steps:

  1. When the vehicle comes to a complete stop, the brake pressure is detected.
  2. Auto Hold engages and locks the brake pressure via the electronic control unit.
  3. The driver removes their foot from the brake pedal, and the vehicle remains stationary.
  4. When the accelerator pedal is pressed, the system automatically disengages and the vehicle begins to move.

As this process is entirely automatic, no additional action is required. Auto Hold functions as an extension of the electric parking brake, and these two systems are typically designed together.

Where is the Auto Hold Button Located?

The button that activates and deactivates the system is usually located around the gear lever, next to the electronic parking brake.

The button's location may vary depending on the vehicle model, but it is mainly found in the following places:

  • Centre console
  • Next to the electronic parking brake lever
  • Panel where the driving modes are located
  • In some vehicles, the button group under the steering wheel

The button usually has the letter ‘A’ and a brake symbol underneath it. This symbol represents the system's automatic brake hold function.

How to Use Auto Hold

To use Auto Hold, simply press the button to activate the system.

The system is used as follows:

  1. Start the vehicle and fasten your seatbelt.
  2. Press the Auto Hold button to activate the system.
  3. When you stop the vehicle, press the brake pedal as normal.
  4. When the system engages, the Auto Hold indicator appears on the instrument panel.
  5. You can remove your foot from the brake pedal; the vehicle remains stationary.
  6. To move forward, simply press the accelerator.

Due to this method of use, the system is fully compatible with automatic transmission and electronic parking brakes. It may also be available in some manual transmission vehicles, but its prevalence is lower.

The Auto Hold indicator shows that the system is active and that the brake pressure is being controlled by the device. On the instrument panel, it is usually:

  • Green: System is active and engaged.
  • White: System is active and ready to engage.
  • Yellow: There may be a warning or fault in the system.

This indicator allows you to quickly determine whether the system is engaged or disengaged, particularly during stop-start situations.

Auto Hold faults may occur due to issues with sensors connected to the braking system or the electronic control unit.

The main causes of faults are as follows:

  • Worn brake pads
  • Insufficient hydraulic brake pressure
  • ABS or ESP sensor faults
  • Electronic parking brake faults
  • Low battery voltage
  • Hall sensor problems

In such cases, an Auto Hold fault warning appears on the instrument panel. The system is disabled in this situation and the vehicle's braking function is left to the normal brake pedal.

When a fault is detected, the best course of action is to consult a service centre, as the problem is electronic in nature and requires professional inspection.

Under What Driving Conditions Does Auto Hold Offer Advantages?

This feature, which is particularly useful in stop-and-go city driving conditions, provides practical support that enhances both comfort and safety.

Auto Hold offers great convenience in many situations during daily driving. In particular:

  • In heavy traffic
  • When going uphill or downhill
  • When waiting at long traffic lights
  • On routes within the city that require frequent stop-and-go driving
  • When manoeuvring at low speeds
     

It makes the driver's job easier. By reducing pedal control in these conditions, it makes driving more controlled and effortless. Additionally, Auto Hold can reduce the risk of the vehicle rolling away, providing a safer stop-start experience, especially for new drivers.

Can Auto Hold be turned off?

Yes, Auto Hold can be turned off when desired. The driver can deactivate the system by pressing the button again. In some vehicles, the system automatically disengages when the ignition is turned off, while in some models there is a memory feature and it remembers the last setting, starting in the same state when turned back on.

Points to note when using Auto Hold

Although Auto Hold technology is practical, it is important to pay attention to certain points:

  • Do not continue to use the system if it gives a fault warning.
  • Do not overload the vehicle on very steep ramps.
  • Press the accelerator pedal gently during sudden starts.
  • The system may be more sensitive on snowy and icy surfaces.

Paying attention to these warnings is important for safety. Furthermore, it is important to remember that Auto Hold may activate differently in each vehicle. Understanding how the system works before driving ensures a smoother and safer experience, particularly in heavy traffic or when starting on inclines. This allows you to maximise the system's efficiency and prevent unexpected reactions.

Comfortable Driving Choice in Vehicles with Auto Hold

The system offers ideal driving support for all drivers seeking comfort and safety. It provides a significant advantage, particularly for drivers who spend time in city traffic, travel on hilly roads, or frequently stop and start. It reduces physical strain for you and makes controlling the vehicle safer.

Choosing the right vehicle is also important for a comfortable driving experience.
