Park information is a parking helper that steers your car into a space
Park information is a feature in some vehicles that automatically steers the car into a parking space while you control the brake and accelerator. The system uses sensors around the car to detect empty spaces, measure them, and guide the steering wheel — you stay in control of speed and braking. It is not a fully self-parking car; it is a steering aid that handles the wheel angle while you handle the pedals.
Different car manufacturers call this feature by different names. BMW calls it Active Parking Assistant, Mercedes calls it Parktronic, and Volkswagen calls it Park information. The basic idea is the same across brands: sensors find the space, the system calculates whether the car fits, and if it does, the steering moves on its own while you manage speed.
Park information is most useful for parallel parking — fitting your car between two others along a street — because that is where steering angle matters most. Some systems also handle perpendicular parking, where you back into a space at a right angle to the curb. Straight-in parking from a lot aisle usually does not need the feature because the space is wide and the angle is straightforward.
Key Takeaways
- Park information steers the wheel automatically while you control the brake and gas pedal, making it a steering aid rather than a fully self-parking system.
- The system uses ultrasonic or radar sensors around the car to detect empty spaces and measure whether your car will fit.
- Park information works best for parallel parking and is most common in luxury and mid-range vehicles, not in budget cars.
- You must stay alert and ready to take over steering at any time, because the system does not replace your attention or responsibility.
How the sensors find and measure a parking space
Park information relies on ultrasonic sensors or radar sensors mounted around the bumpers and sides of the car. As you drive slowly past parked cars, these sensors send out sound waves or radio waves and measure how long it takes for them to bounce back. That timing tells the system how far away the parked cars are and how much empty space sits between them.
The system needs a space that is roughly 1.5 times the length of your car to work safely — so if your car is 15 feet long, the empty space should be at least 22 to 23 feet. If the gap is too small, the system will not attempt to park. Once it finds a suitable space, it calculates the steering angles needed to fit your car in without hitting the cars on either side.
The sensors keep working while the system steers. If an obstacle moves into the space — another car, a person, a shopping cart — the sensors detect it and the system stops steering and alerts you. This is why you must stay ready to brake or take over the wheel at any moment.
What you do while Park information steers
When you set up Park information and the system finds a suitable space, you shift into Reverse (for parallel parking) or Drive (for some perpendicular systems). The steering wheel begins to move on its own — you will see it turn without you touching it. Your job is to keep your foot ready on the brake and watch the screen or mirrors to make sure nothing unexpected happens.
You control the speed by using the accelerator and brake pedal. Most systems ask you to move slowly — usually 2 to 5 miles per hour — so the steering has time to work and you have time to react if something goes wrong. Some newer systems will also control the speed for you, but you still need to be ready to brake.
The process usually takes 10 to 30 seconds depending on the space size and the car's length. Once the car is centered in the space, the steering stops and the system tells you it is done. You then take full control and make any small adjustments you want.
Which cars have Park information and what it costs
Park information is most common in luxury brands like BMW, Mercedes-Benz, Audi, and Lexus, where it is often included as standard or as part of a technology package. Mid-range brands like Volkswagen, Volvo, and Kia also offer it, usually as an optional add-on that costs between $500 and $1,500 depending on the brand and model year.
Budget car brands rarely include Park information because the sensors and steering software add cost and complexity. If you are shopping for a used car and want this feature, check the window sticker or owner's manual to see whether it came with the package. Some dealers can retrofit it, but that is expensive and not always possible on older models.
Newer vehicles sometimes offer 360-degree camera systems or surround-view displays instead of or alongside Park information. These show you a bird's-eye view of the car and the space around it, which helps you park manually without the steering automation. Both features make parking easier, but they work in different ways.
When Park information does not work or may fail
Park information will not set up if the space is too small, if the sensors are dirty or blocked, or if the car's battery is low. Rain, snow, and mud can cover the sensors and prevent them from detecting spaces accurately. If you have just washed the car or driven through a car wash, wipe the sensor areas clean before using the feature.
The system also struggles in tight urban spaces where cars are parked very close together or at unusual angles. Angled parking, diagonal spaces, or spaces on steep hills may confuse the sensors. In these situations, the system may not detect the space at all, or it may detect it but refuse to attempt parking because the geometry does not match what it expects.
Park information can also fail if the steering system itself has a problem — a fault in the power steering motor, a broken sensor wire, or a software error. If the system stops working, you will see a warning light on the dashboard. Have a mechanic check it, because it usually means a sensor or electrical connection needs repair.
Park information versus other parking technologies
Park information is one of several tools that make parking easier. A backup camera shows you what is behind the car when you reverse, which helps you see obstacles and judge distance. A 360-degree camera system displays a top-down view of the car and everything around it, so you can see the space and the curb clearly. A parking sensor system beeps or displays distance warnings as you get close to obstacles.
These features work together. You might use the 360-degree camera to find and judge the space, then use Park information to steer into it, while the parking sensors alert you if you get too close to a bumper. None of them replace your attention or your responsibility to drive safely. They are all aids that give you more information or automate part of the task.
Some very new vehicles offer fully automated parking, where the car parks itself with minimal input from you — you may only need to press a button. This is different from Park information because the car controls speed, steering, and braking all at once. Fully automated parking is still rare and expensive, and it is not yet standard on most vehicles.
Safety and responsibility when using Park information
Park information is a convenience feature, not a safety system. You remain responsible for the car at all times. The system can malfunction, the sensors can be fooled, and unexpected obstacles can appear. You must stay alert, keep your hands near the wheel, and be ready to take over steering or braking when ready if something goes wrong.
Never use Park information in a space where you cannot see clearly — for example, at night without good street lighting, or in heavy rain or snow. Do not rely on the system to detect small obstacles like children, pets, or shopping carts. Always look around the car before activating the feature, and keep watching while it steers.
If the system behaves strangely — if the steering jerks, if it tries to park in an unsafe way, or if it does not respond to your brake input — take control when ready by turning the steering wheel or pressing the brake. Do not assume the system knows what it is doing. Your judgment and attention are always more important than the automation.
Frequently Asked Questions
Can Park information park in a space that is only slightly bigger than my car?
Most systems need a space that is at least 1.5 times your car's length. If the gap is smaller, the system will not attempt to park because it cannot fit safely. Some newer luxury vehicles claim to work in tighter spaces, but you should always verify this in your owner's manual for your specific car.
What happens if Park information starts steering and then detects an obstacle?
The system stops steering when ready and alerts you with a beep or warning message. You take control of the wheel and pedals. The system does not brake for you in most models, so you must be ready to stop if something unexpected appears.
Do I need to do anything to maintain Park information?
Keep the sensors clean and free of mud, snow, and debris. Check your owner's manual for the sensor locations — they are usually around the bumpers and sides. If the system stops working, have a mechanic scan the car for sensor faults or electrical problems.
Is Park information the same as self-driving or autonomous parking?
No. Park information steers the wheel while you control speed and braking. Fully autonomous parking systems control all three — steering, speed, and braking — with minimal input from you. Park information is much more common and much less expensive, but it requires more active involvement from the driver.
Will Park information work if my car is very long or very short?
Park information is calibrated for your specific car model, so it accounts for length and width. Very long vehicles like trucks or SUVs may need larger spaces, and very short cars may fit in tighter spaces. The system adjusts its calculations based on your car's dimensions, which are programmed into the software.
