MDM Mode
This is the MDM Mode Indicator (M Dynamic Mode) text symbol. Quite simply, it refers to a drive mode available in one model, the M, from one Manufacturer, BMW. M Dynamic Mode makes it possible to “drive on a dry roadway with high longitudinal and transverse acceleration but with limited driving stability”. This is automotive tech speak for transferring near full control to the driver.

M Dynamic Mode is activated by pressing the stability control off button. This results in the illumination of both the MDM and the stability control OFF symbols. The use of MDM actually shuts off the stability control system. According to BMW, stability control will only be activated when the absolute limit of stability is reached. This is pretty much impossible to define.

BMW Symbols
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.
Some BMW and Mini models already require that the key fob be inserted into the dashboard next to the Start/Stop button. If the key fob battery is dead, the vehicle will recognize the fob when inserted. In “Comfort Access” models, the slot is only needed if the fob’s battery dies, or if electrical interference interrupts the fob’s signal. Insert the fob into the slot and use the Start/Stop button as normal.
For other BMW or Mini models, hold the remote control against the marked area on the steering column and press the Start/Stop button within 10 seconds while depressing the brake.
The smart phone recharge pads also act as new start points. A properly connected key card or a smart phone holding the proper BMW app touched to the pads will allow the car to start. The pad is found in front of the cup holders in the i4 (first image) and on the lower level of the iX console (second image).
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.
The car features a wireless cell phone charging station inside the center console. There is also a bulge into which the Display Key can be slipped, with the lock button up and out. The Key is charged with a micro USB cable, a micro USB port on the Key (see the arrow on the Display Key) and the USB port at the back of the console.
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.
In this case, you might try using a device like a carabiner or snap hook. It can be hooked to a strap 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.
An Actual Death Trap

inside. I immediately pointed out that there IS a way out — just not where you would expect to look. The unlock button is placed in the middle of the dashboard, and the entire group was clearly unfamiliar with this quirk in a BMW. And it belongs exclusively to BMW.
Back to technology and design, Tesla’s vehicles all feature electronic latches. As to getting out, the rear doors in the Model S require pulling a cable located under each rear seat. The front doors are released mechanically from the inside.
The latest Lincoln Continental also has electronic door latches. A back up release is just below the armrest but still on the door, and only the driver’s door. However, Lincoln says that the doors will not remain latched if the power goes out.
Can Your Car Windows Open on Their Own??
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.
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.
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.
