"Secret" Features Revealed – Are They in Your Car?

Do you know everything your car can do? The chances are slim. But now a review from Carwow reveals a number of its 'secret' features.

New cars often have a number of hidden features, and many drivers are not even aware that they exist.

These features can vary significantly between car makes and models, and knowledge of them can in some cases make car ownership easier or more informative.

Motoring journalist Mat Watson has taken a closer look at the subject. In a new video, he takes a closer look at 31 of these 'lesser known' features.

– Most new cars come with secret features that many car owners don't know about.

In the clip, he demonstrates various examples of these functions, of which we look at a selection here.

Many drivers are completely unaware of their cars' functions.

One of the most common functions, which is also among the most overlooked, is hidden in the car's instrument cluster.

Here, a small arrow next to the fuel icon indicates which side of the car the fuel cap is located on. Maybe not the world's greatest technical breakthrough. But it's useful for the forgetful or on a day when things just need to go extra fast.

A more specific feature is available in certain Volvo models, including older V70s, which are equipped with a car key with an information button.

These keys may have a built-in sensor. The feature allows the car key to emit a signal indicating the presence of a person inside the car, based on heartbeat. Mat Watson explains the purpose.

– It can detect if someone is hiding in the car.

Another feature is seen in some Nissan models, such as older versions of the Nissan Qashqai.

When you fill the tires, the car beeps when the correct air pressure is reached. This means the driver does not need to use a separate pressure gauge during filling.

Of that feature, Watson says, "This is something I've never seen before."

Tesla's cars also have several features, some of which are more well-known than others.

A lesser-known feature is the so-called 'Joe Mode.' When activated, this mode significantly reduces the sound level of all non-critical warning sounds in the car.

"This means that the children don't need to be woken up on long journeys," explains Mat Watson about the feature.

Finally, there is an interactive detail in the voice assistant systems of both Mercedes and BMW. The systems can sometimes be perceived as communicative.

If you ask the system a question about its perception of a competitor brand, you can get a specifically programmed answer back. Watson comments: "Even though the system is German, it actually has a bit of humor."

Mat Watson's walkthrough covers a total of 31 different features. Those interested can find more details and see all the examples in the video, which we also link to in this article.
