Mercedes Benz Symbols
So, what is that light on your dashboard? What follows is easily the most complete list available of symbols and warnings that may appear in and on your car’s dashboard or instrument cluster.
The following are warning lights and indicators found in vehicles built by Mercedes Benz. Click the link to the right of each one to learn more.
How They Are Presented
They are roughly ordered by importance, which tends to be by color (red, amber, yellow, orange, green, blue, black, white), but there are over 70 of them so be patient!
Note also that the company makes extensive use of the information display, so a great many of these are simply black and white.
Models examined include A, AMG, B, C, CLA, CLS, E, G, GL, GLA, GLC, GLE, GLK, GLS, GT, M, S, SL, SLC and SLS Class and Series vehicles.

Remember that only proper service and repair procedures will ensure the safe and reliable operation of your car. In addition, proper safety procedures and precautions, such as the use of safety goggles, the right tools and the equipment should be followed at all times to eliminate the possibility of personal injury or improper service which could damage the vehicle or compromise its safety.

Technology is always changing and what is current and accurate today may be literally out-of-date and inaccurate tomorrow.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.

The dozens of images on this page are all Drive Mode Indicators 
Drive modes are chosen by the driver and either enhance power and performance, enhance fuel economy or maintain a balance between them. If you see one of these, just know that the drive mode can be changed with the press of a button or tap of a screen. The last three are Track Mode Indicators and should only be used on a closed track.
Similarly, these are Race Mode Indicators. They are part of a Performance Traction Management (PTM) system that offers Competitive Drive Modes. When activated, the Electronic Stability Control OFF light will also be seen as the system will be turned off. As above, these modes should only be used on a closed track.
This is an N Launch Control indicator. The symbol is seen when N Launch is chosen. N Launch provides maximum acceleration when the vehicle is at a complete stop, which truthfully sounds like what any vehicle has when the accelerator is floored. However, N Launch is a special case from Hyundai in their Ionic 5 and 6 model EVs. When N Launch is selected, in use the brake and accelerator pedals are fully depressed. The car is “launched” when the brake pedal is released. N Launch is cancelled when the accelerator is released.,
Electric vehicles have their own set of mode choices, in nearly the number of variations as vehicles powered by internal combustion engines. Again, its all about the driver’s choice!
Toyota’s hydrogen powered Mirai has this Br – or Brake – Mode option, which is found on the shifter. It is intended for driving in conditions that require strong deceleration force, such as down-hill driving, etc. The indicator will be seen when the mode is selected, which draws braking power from the traction battery.
Another mode is Valet. This one leaves only the door locks and ignition active or available for use by a valet to park an owner’s vehicle. Forgetting to disengage this mode will lock out the trunk and glove box, and may be temporarily confusing.
These are all Sport Mode Indicators. plain ‘S’ is used both as a Sport Mode Indicator and a SynchroRev Match Mode (S-MODE) indicator. The SynchroRev Match mode is found only in a vehicle equipped with a manual transmission. It automatically adjusts the engine speed to match the selecting gear ratio while changing gears. Similarly, the two Sport Mode Indicators that follow will downshift an automatic transmission when engaged and enables performance shift features when spirited driving is detected, maintaining lower transmission gears to increase available engine braking and improve acceleration response.
One manufacturer uses multiple mode options that can be set by the vehicle’s driver. The first uses a distorted letter V to indicate that V-MODE is chosen. The option exists only as part of a V-Series vehicle. Z MODE offers exactly the same options, but in another model. It indicates that a specific driving mode has been chosen as set by a specific driver. The image of a head and shoulders alone or alongside a steering wheel are MY MODE indicators from the same manufacturer. Again, drive options are chosen by the driver.
Yet another manufacturer uses the symbol on the left to indicate N mode, which is seen as a stylized letter N. It actually controls the vehicle’s SPORT modes, and thus makes little sense. There is no explanation for what the N actually stands for and it is activated by pressing a flag button on the steering wheel. N mode manages the driving dynamics by automatically adjusting the steering effort, and the engine and transmission control logic for enhanced driver performance.
These are Tour or Normal Mode Indicators. It is used for normal city and highway driving to provide a smooth, soft ride in a high-performance vehicle. 
It provides a balanced setting between comfort and handling and is the standard mode. Be sure not to confuse it with the image to the right, which is essentially the same image but seen in yellow/amber. It is a Lane Keeping Indicator. 
These are all Weather Mode Indicators: two forms of Rain and Snow Mode, Wet Mode and Dry Mode. Other than Dry Mode, the modes help to keep the wheels from spinning in slippery conditions.
These are (Electric Vehicle) 
These variations also leave out the word mode. The first indicates that the vehicle is being driven as an electric vehicle only, as above. But the second symbol adds what is intended to be a clock in the corner. It means that EV mode and the high voltage battery is being saved for a more useful and economical time. It does not and can not indicate a specific time. The last one, with the line through the E and an arrowed circle, indicates that high voltage battery does not have enough juice to operate the vehicle without the help of the gas engine.
These symbols come by way of Jeep and their new hybrid models, and are Hybrid Drive Mode Indicators. They are seen in white in the information screen. In Electric (EV) Mode, the car runs exclusively on the high-voltage battery until its charge is used up. In Hybrid Mode, the vehicle operates on whatever on all the internal combustion engine and battery power available. In e-Save mode, the battery is reserved for later use.
This is a Green Zone Indicator. It depends on navigation information to tell a hybrid model to extend the use of EV mode in urban areas to protect the local atmosphere. These areas may be parks, hospitals, schools, and the like. Green zone operation can be expanded by the vehicle depending on driver history.
Recall GM Coupes Before Someone Else Dies!
Yet another cringe worthy headline showed up on Twitter recently (September 2018). A man trapped in his car because the battery was dead. And for 14 hours. He was very, very lucky that the car wasn’t outside in the sun, or the outcome would have been very, very different.
This one hits home for us because of another incident several years ago that prompted this article on this site, but in this case, a man lost his life. So, all this needs a more thorough examination.
The problem is finding oneself locked in a car that has lost its power. It is a direct result of the move to all
electronic everything, right down to the door latches. It is also the result of very, very poor design.
Both of the incidents involve GM Coupes: a Chevrolet Corvette and a Cadillac XLR. They feature these flush door handles with a electronic button inside this opening that unlocks and opens the door if the key fob is present. If the power is lost when inside the car, the electronic button on the armrest no longer works, and while there is a back
up option, it is not remotely obvious and effectively not intuitive.
Where’s the Release?
The back up option is a mechanical release handle on the floor below the door, not on the door where any typical human would think to look. In the most recent episode, the owners manual was missing from the 12 year old XLR, which is all too common in older vehicles. And he didn’t have a cell phone with him, or he surely would have
been out of his car much sooner.
In the previous incident, the gentleman had gone to the car to check on his dog, leaving his cell phone behind. Relatives reported that there was evidence that the man was looking through the manual for help when he succumbed to the heat. He and dog passed away.
It is far too easy to blame the victim here. It is true that they were not familiar with the feature. Both cars were bought used, so expecting the seller to go over more obscure features is wishful thinking.
Age Again?
It is also way too easy to blame age — the men were 75 and 72, respectively. This is when I point to an incident relayed by 20 year olds. Their friend had bought a new BMW. He then let them in the car to check it out and locked the car from the outside.
The joke was that there was no way to unlock the doors from the
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.
Age is NOT the issue. Expectation and intuition is. Where did these 20-somethings look for an unlock button?
The Model X front doors are all mechanically released from the inside. Perfect.
The Model 3 has a mechanical handle exactly where you would hope. On the armrest pretty much where a hand would actually be while using the armrest. It was tempting to simply open the door with it each time. A superior design.
The last two examples are far better thought out. And before anyone else finds themselves trapped in a GM Coupe, irrespective of age, we think a new way to open the doors from the inside must be devised and the cars recalled.
In our last show, we talked about changing the behavior of the one vs the behavior of the millions. And this is yet another example.
Changing the one, the manufacturer, eliminates the need for millions drivers to read, and frankly memorize, crucial new features or the entire owner’s manual. It also eliminates the need for millions of salespeople to somehow suddenly become effective teachers. Someone else’s dad, mom, brother, sister, son, daughter, husband or wife should not have to die or nearly die over poorly thought out designs.
