Why Are My Windows Open?
If you’ve ever walked out to your car and found all the windows open, this is our subject. We’re going to discuss a feature found in cars from a number of manufacturers that catches people with their pants down. Or their windows down. This is not about a fault or a system failure or a warning light, but about something working exactly as it is supposed to, but doing it seemingly at random on its own.
Vehicles made by BMW and Mini, Honda and Acura, Ford and Lincoln, Maserati, Mercedes, Toyota and Lexus and Volkswagen Group, include what is called a convenience feature, which opens all the windows for ventilation when the unlock button is pressed and held. The sunroof will be open as well and the car unlocked.
From what we’ve discovered only Mercedes and some vehicles made by the Volkswagen Group offers the option to close everything again using the lock button. The Honda we have here does not.
Its An Accident!
So, what is causing the surprise window openings can be explained by accidental button pushes. Whether carried in a bag or in a pocket, something pressing on the unlock button for an extended period can and will activate the feature, if the key fob is within 50 feet or so. Remember that while the key fob’s keyless access can only operate within 18 to 24 inches of the vehicle, the buttons on the fob will work from a much greater distance.
For a fob carried in a pocket, preventing this may be a simple as turning the fob over on the key ring. The buttons will face the other way, if like me, your keys rest in the pocket the same way each time.
If it is carried in a bag, the nature of keyless open and start can easily lead to the fob migrating to the bottom of the bag. In this case, you might try using a device like this carabiner or snap hook. It can be hooked to a strap like on this computer bag and still actually be closed into the bag. But it won’t work its way to the bottom. The devices come in many different sizes and colors so you can be a stylish as you’d like and they can be found online or at most hardware stores.
To finish off the functions of the actual convenience feature, the windows will stop short if the button is released, and will continue down if it is pressed and held yet again. Some vehicles require the unlock button to be pressed and released once before the convenience feature will work. In Honda and Acura vehicles, the feature will work by holding the mechanical key turned to the right in the key cylinder, but this will not happen accidently. Also, turning and holding the key back to the left will close the windows and sunroof.
The feature can be disabled in Ford Motor Co and Toyota and Lexus vehicles, but you’ll need your dealer. In fact, the feature in a Toyota and Lexus must have first been activated in this way.
So, if ever you find your windows wide open one day, don’t panic — find a new way to carry your key fob.

Technology is always changing and what is current and accurate today may be literally out-of-date and inaccurate tomorrow. And when it comes to the current state of flux in the auto industry, nothing is more true.

So lets set some parameters. Our first thought is to look for Troubleshooting chapter. So, result #1 is that not a single one of these 25 manufacturers have a chapter with this title. Only 3, Mazda (right), Toyota and Lexus, even use the word Trouble. Emergency, Roadside or Breakdown are most likely to be found, and this is a pretty short hurdle. VW raises the hurdle, with a Do It Yourself chapter that includes flat tires and dead batteries, etc. that tend to be found in the Breakdown chapters from other manufacturers.
So, back to the our troubleshooting-like chapters. Once inside, only Honda/Acura, Toyota/Lexus and Subaru got this right! Setting aside for a moment the fact that the owner’s manual is most likely inside the car and the driver locked outside, at least if the driver manages to get the car open, he or she will be able to get started.
Subaru (right), Lexus and Toyota chapters point directly to pages with solutions to issues with the electronic keys. Again, it may not be obvious to the driver that the key fob is the problem, but these manufacturers come the closest to nailing the problem. Titling the sections using something like what to do if the car does not respond to the electronic key would come closest to replicating exactly what the driver is experiencing.
There are several methods for starting a Honda or Acura vehicle. To start a Honda and the newest Acura models lacking a slot, touch the “H” in the Honda logo or the “A” in the Acura logo on the remote control to the Start / Stop button until the small indicator light in the button begins to flash. For the next 30 seconds, the vehicle can be started using the Start / Stop button normally. You can also simply press the Start / Stop button with the remote control itself, while stepping on the brake of course.
exactly the same.
In earlier Acura models (newest models are above), there is a slot for the remote control (key fob) to the left and below the Start / Stop button. Insert the remote and use the Start / Stop button to start the vehicle as normal.
In the oldest keyless start Acura models, there is a cover on the ignition switch that must be removed. This will allow the use of the mechanical key built into the key fob. To remove the ignition switch cover, slip the built-in key into the parallel slot underneath the cover. Push the key in while pull it towards you at the same time and the cover will come off. Once the cover is removed, the mechanical key can be inserted and turned to start the vehicle.
Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.
If you’ve ever walked out to your car and found all the windows open, this is the subject. Keyless start vehicles made by BMW and Mini, Honda and Acura, Ford and Lincoln, Maserati, Mercedes, Toyota and Lexus and Volkswagen Group, include what is called a convenience feature, which opens all the windows for ventilation when the unlock button is pressed and held. The sunroof will be open as well if there is one and the car unlocked.

New Honda and Acura EVs Require New Dashboard Symbols for a Very Surprising Reason
The introduction of the Honda Prologue and Acura ZDX electric vehicles in 2024 required us to add several new dashboard symbols to the manufacturer’s respective pages. Well, actually, new old symbols.
This is because we already had the symbols in play — on pages for General Motors
(GM) models!
What’s happened is that Honda and GM jointly developed the EVs, a collaboration that began in 2013, which was focused on hydrogen fuel. That shifted as EVs rose to prominence and in essence, GM‘s drivetrain and control systems won out. And the proof is in the owner’s manuals!
The cover pages of the Honda and Acura models are properly identified. Then comes page one…
Tables of Contents
Below in order are the table of contents for a Chevrolet Malibu (left) and the Honda Pilot (right). And then below left is the TOC for the Honda Prologue.
The majority of the additions are of course related to the fact that the vehicles are fully electric. So all of the resulting indicators and warnings related to the high voltage system are found.
Remember that auto manufacturers are given great leeway in the way they present warning symbols and indicators. Only a few are identical from one manufacturer to another. Most of the time symbols end up looking similar but differ enough for us to address here on this site. Hence the fact that we host over 1,000 of them here!
