Stability Control
These are Stability Control Off Indicator symbols. One of these lights, or one of the text versions below, tell you that the stability control system is deactivated. Your vehicle’s manufacturer may call this AdvanceTrac, Automatic Stability Control (ASC), Dynamic Stability Control (DSC), Dynamic Stability and Traction Control (DSTC), Electronic Stability / Stabilization Control (ESC) …
- And there’s still more. But first, is it truly your symbol?? If yes, continue on below.
- Otherwise return to our main Picture Symbols page and scan again!
… Electronic Stability Program (ESP), Interactive Vehicle Dynamics (IVD), Precision Control System (PCS), StabiliTrak, Vehicle Dynamic Control (VDC), Vehicle Dynamics Control Systems (VDCS), Vehicle Stability Assist (VSA), Vehicle Stability Management (VSM), Vehicle Stability Control (VSC), etc.
Regardless of the system’s name, the light means the same thing. The system is currently off. The vehicle will operate normally – that is, without the stability control enhancement – with the advanced system off. Note that the second image, with a sideways car on a wavy line with a tree next to it may illuminate in green! Every other version comes on in yellow/amber when the system is turned off.
Many More Versions
Note that BMW uses what it calls M Dynamic Mode (MDM) in their M-Series vehicles. When M Dynamic Mode is in use, the stability control system is turned off and the Stability Control Off indicator is illuminated. In most but not all of these models, a corresponding MDM indicator will appear.
The image to the left is very, very similar to an “OFF” indicator, except it is a NOT READY indicator. The indicator will most commonly be seen only on start up and should go out in a few seconds. It may stay on longer in cold conditions and will go out once the vehicle is warmed up. However, if it persists, there is clearly a problem that should be addressed as soon as possible.
Stability control is a sophisticated electronically-controlled system that uses sensors in tandem with other systems to identify when there is lateral slip in the tires during cornering and responds by adjusting the brakes, throttle, differential and/or suspension to help keep you on track. Thus, the system is automatically turned off when the Check Engine Light is activated in order to prevent inaccurate readings sending incorrect instructions to the system. The image of a skidding car is overly disconcerting.
These text symbols, or one matching one of the other acronyms, will be seen in some early model vehicles that use the system. Newer vehicles are more likely to use the picture symbol above.
Here’s a video describing when and how these lights may appear.

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.
This symbol is a Brake Trouble Indicator symbol. They could indicate a serious problem with the brakes. However, the light will also be on when the hand, or emergency, brake is engaged.
This symbol is a Parking Brake Indicator. There are a number of considerations. The symbol to the right simply indicates that the parking, or emergency brake is engaged. Be sure to disengage the parking or emergency brake before driving.
One of the first idiot lights, this warning light features an old-school oil can. It is the Oil Level or Oil Pressure warning lights or symbol. A wavy line below the oil can indicates the oil level is low. Without the wavy line, your engine is telling you that the oil pressure is low.
There are several versions of the dreaded Check Engine Light, and this one is the most common. It is one of the oldest of the symbols that you may see. The word “Check” may appear inside the image, or below, or not at all.
One of the original idiot lights, at least in red, this is the Temperature Warning light or symbol. In red, it indicates quite simply that the engine temperature is too high. If you see this light, your vehicle should be stopped and the engine turned off as quickly as possible. Turning on the heater to the highest setting will remove some of the heat as well. Contact your dealer or authorized service center as soon as possible.
This is the Master Warning Light symbol, in red. If this light is on, there will likely be text displayed as well on the instrument panel, or another warning light. Look for text in particular. It could very well point out something as serious as low oil pressure. However, despite the serious look to the symbol, it is generally associated with simple reminders such as a door ajar or that it is time to change the oil.
This is the Tire Pressure Monitoring System (TPMS) or Tire Pressure Monitor (TPM) warning light symbol. It is also used as Flat Tire Monitor (FTM), which seems redundant. The tell-tale comes on when the inflation on one of the tires is reduced about 25% or more. In most cases, that will be about eight pounds. This is easily the most misunderstood symbol you will ever see on your instrument panel.
The image of a car with squiggly or wavy lines behind it is the Slip Indicator symbol. When a vehicle detects slippery conditions, its stability or traction control system is activated. The light will flash, irregularly in some vehicles, indicating that the system is doing its work, helping to keep the vehicle in control.
This is a Reduced Engine Power Indicator. Only a handful of manufacturers use this light, which comes on automatically with a reduction in the vehicle’s performance. Given what is likely an obvious reduction in power and acceleration, the symbol itself becomes redundant. The image is the same one used for the Check Engine Light above, with the added arrow pointing down.
This combined system warning indicator covers the Electronic Stability Program (ESP) and the Brake Assist System (BAS). These systems work together, and a fault in either, or both, will cause the light to come on. If it remains on, see your dealer or authorized service center.
This is the primary Key Fob Indicator. A number of picture symbols are used to indicate the presence of an electronic key in a push button or, ironically, keyless start, or keyless ignition, vehicle. These systems will allow a vehicle to be started only when an electronic key is present in, and detected by, the vehicle.
This is an Intelligent Brake Assist (IBA) Off Indicator symbol. IBA uses lasers to identify approaching obstacles and applies the brakes accordingly. The light comes on when the IBA switch is turned off. If the light comes on while the system is on, it is either unavailable temporarily or is malfunctioning. Check that the laser sensor is clean, when it is safe to do so.
Cruise Control Indicator light in text form. This light is illuminated when the cruise control is engaged. It is perfectly straightforward, as opposed to the two image symbols below that are now often used in its place.
This is the most common Check Gas Cap Indicator symbol. It is one of the few things the average driver can do anything about. The image, which is really half of a car with an unscrewed gas cap, can look like a water pitcher with a screw or bolt next to it.
These are Park Assist Indicator symbols. The green version will be visible when the system is activated and working. The manufacturer may refer to this as Intuitive Parking Assistance, Park Distance Control (PDC), etc. It looks like a sail with lines radiating from it!
This is a Low Windshield Washer Fluid Indicator symbol. Fill the windshield washer fluid reservoir as soon as possible. The image actually resembles an open hand-held fan, which is supposed to be the windshield. The dashed lines represent two steams of water.
The acronyms AFS and AFLS in these symbols or indicators stand for Adaptive Front-lighting System or Adaptive Front Lighting System. The difference is very subtle and is the result of a manufacturer choice only.
This symbol is a Tail Light Indicator symbols. The replacement of a light bulb or two will restore order. Some manufacturers add a text message in the instrument panel noting exactly which light is out. The symbol is often described as eyelashes coming out of the back of a car!
This symbol is the High Beam On indicator. The light is active only when the high beams are active (turned on) and has been a standard in vehicles for decades. It is one of only a select few presented in a blue color.
This the Fog Lamp Indicator symbol. The indicator in green is active only when the fog lamps are activated. The wavy or squiggly line crossing straight ones is meant to indicate light passing through the fog.
These are Headlamp Out Indicator symbols. One or more of the headlamp bulbs is burned out or malfunctioning. This is another symbol that may utilize an exclamation point, which always indicates a problem, even if its in the green color. Another symbol in yellow/amber only is an alternative Lamp Out indicator.
These are all Slip Indicator and Electronic Stability Control (ESC) or Fault 
The indicators may also be in text form. Some manufacturers also include an intermittent beep while the system is active. Your dealer or authorized service center will be best equipped to address problems with the system.
But again, for the most part, these images appear 
The image with its squiggly or wavy lines behind a car, is unfortunately that of a car in a skid, which can be more than a little unnerving, particularly to drivers unfamiliar with the symbol’s meaning. It is seen whether the system is working to keep the vehicle in control and when the system is off, which the strike through line indicates. The addition of the wrench also indicates that the vehicle has detected a fault in the system. Again, the vehicle will operate normally, but without the advanced control system.
The last image to include is the triangle with an exclamation point inside. Some older vehicles that were first to offer stability control use this as a Slip Indicator or as a Fault Indicator. That is, it is seen when the system is doing its job and keeping the vehicle in control when a slip or skid is sensed, as was noted above.
