New cars are becoming safer and safer with every new release. This comes in the form of physical safety features, with better crumple zones and sensors, to software features such as the Warn and Brake system fitted to the Porsche Taycan brakes.

This feature is designed to warn you of impending head-on collisions, initiate the appropriate braking maneuvers, or provide steering assistance. In this article, we will look at what Warn and Brake is, how to turn it on and off, and what the system’s limitations are.

It is worth noting that Porsche’s Warn and Brake feature is a safety assist and should not be a substitute for driving with due care and responsibility. While it is an aid that has, and will, save many lives, it is simply that: an aid.

Porsche’s Warn and Brake Assist, more commonly known as Autonomous Emergency Breaking (AEB), is a safety feature that first appeared in the late 2000s on high-end vehicles. However, more recently, it’s become a standard safety feature on new cars.

The feature uses sensors on the car to detect and prevent potential accidents. When noting a potentially critical situation, the AEB system will first try to warn the driver that action is needed. If no driver action is taken and a collision is expected, braking and steering will be applied automatically.

The degree of brakes and steering will always depend on the situation. However, the system aims to reduce the speed of the collision or avoid the impact altogether.

Porsche Taycan brakes are fitted with an AEB system, which Porsche has trademarked as ‘Warn and Brake’. This feature is automatically switched on when you turn on the ignition and the car has established operation readiness.

However, there are situations when you should switch it off, such as during removal, when driving off public roads, or during transport, (e.g., on a car transporter, train, or ship).

Learn how to do this in the owner’s manual. I’ve summarized the instructions below.

  • In the car’s settings, go to Assistance.
  • Choose Basic assistance.
  • Select Warn and Brake Assist.

From here, you can change all the Warn and Brake features, including turning the feature on or off. As mentioned above, this feature will turn on whenever the ignition is switched on. Please, be aware of this if you are in any of the above-mentioned circumstances.

System Limits

The Warn and Brake Assist system has its limitations. Not all road users and dangerous situations can be recognized correctly and in time. For example, the sides of the vehicle and the rear area are not monitored.

In some complex driving situations, the system can issue undesired warnings and perform undesired brake interventions. Understanding the system’s limitations and how this could affect your driving is essential.

You’ll find more information about the Warn and Brake system limits in the owner’s manual. Consult it before operating this assist.

System Availability

As previously mentioned, Porsche’s Warn and Brake assist is turned on automatically when the ignition starts, and the car is ready to go.

The system is then available above walking speed and can react to pedestrians or cyclists up to 85 km/h (53 mph). It can also respond to vehicles up to a speed of 250 km/h (156 mph).

However, the system does not respond to animals, crossing vehicles, oncoming vehicles, and objects such as bars, fences, and rail vehicles. AEB systems are designed to be a safety feature in emergencies, not a self-driving system!

System Restrictions

There are several situations where the Warn and Brake system may become unavailable. Please see the list below:

  • Up to 10 seconds after establishing readiness for operation
  • If the seat belts are not fastened
  • In sharp bends
  • In the presence of reflective objects such as guardrails or when entering a tunnel
  • In heavy rain, snow, fog, and ice

I love Electric Vehicles! Been always fascinated how a remote toy car can be used in real life scenarios. I've been an electrical engineer at Energi Elite as well and just decided to write & share about what I've learned here.
