Why do we need a button in a car on which the car is drawn next to a hook or on a slope

New anti-theft systems are installed in expensive cars in several pieces. It is important not only to know about their presence, but also to be able to use them correctly, as well as turn them off if necessary.

What does the label on the button look like?

Drivers of older Mercedes Benz or Volkswagen run into a problem when their dashboard displays a car downhill with a tow hook in the top right corner. Usually this icon is accompanied by the inscription "tow away alarm off".

Such a symbol with an inscription (sometimes without it) can be found on a separate button. Most often, it is located under the ceiling, near the hatch or rear-view mirror. It may have a light indication that notifies that this function is enabled or inactive.

From a simple click in the car, you are unlikely to understand what she is responsible for. To do this, get out of the car and wait for the right moment.

What does the button control

Literally, "tow away" translates as "to tow". It becomes clear that the right moment is the arrival of a tow truck. Level and lift sensors in the car are configured so that the brains of the car understand that it is in limbo.

The alarm is triggered, the ignition lock is blocked. The owner can receive an audio alert.

The "tow away alarm off" button is responsible for forcibly disabling this function. It ceases to be active if the diode on its surface ceases to burn.

When to Use the Alarm Sensor Disable Button

It would seem that the alert function while lifting the car is a useful thing. However, this is not quite true. The sensor does not always work correctly, it can give false positives. Each time such a notification will get on your nerves and not only you. Here are some typical situations where it can be turned off:

1. On a sloped parking lot. Some sensors may work when the car is uphill, nose down. Especially if a car drove nearby at high speed, and your car swayed a little from the oncoming air flow.
2. When transporting a car by ferry. This type of crossing assumes that the car will be subject to pitching. At these times, false alarms may occur.
3. In the event of a sensor failure. Over time, the alarm may begin to act up. She starts to read a lot of false signals. In some cases, you may even get on the road, because the sensor will misinterpret the traffic situation.

Of course, in these cases, we are talking more about older models of cars, where this option was still quite raw. Today, such systems are able to better determine the situation, so they give fewer false positives.

Which button is usually next

The alarm disable sensor is often combined with another security device. Namely, with a volume sensor. This instrument cluster is designed to protect the car during the absence of the driver.

There is a separate button for the volume sensor. It depicts a car with "waves" inside. This security system will work if intruders try to sneak into the salon. It also works on broken glass.

However, various unpleasant situations can also happen to him. For example, he can pick up the movement of a fly in the cabin. Because of this, the car will honk endlessly. This is not very convenient. Because of this, many drivers turn it off.
