Oil Warning Light

Oil warning midOne 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.

Either way, check your oil! Right away! And for more information and more versions of the symbol, click here.

Check Engine Light

Check engine midThere 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.

The image is that of an older style engine seen from the side. It includes a fan blade on its front and an air cleaner mounted on the top. This engine arrangement is rarely seen in modern automobiles and hasn’t been seen in decades and is thus unfamiliar to younger drivers.

The possible reasons for it coming on number in the hundreds and only your dealer or authorized service center can properly address them. However, remember that a loose or missing gas cap will cause the light to come on. This is the only solution available to the average driver, so do check that the gas cap is installed and properly tightened (make sure it clicks at least once).

Important! If other symbols are also active, note that the Check Engine is your first concern. In some cases, other systems in the car may be shut down until the reason the Check Engine light is active is addressed, and the symbols associated with those symbols may be activated. Be sure to check our Multiple Symbols page for more information.

Temperature Indicator

Temperature warning midOne 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.

Master Warning Light

Master warning midThis 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.

Tire Pressure Monitoring System Indicator

TPMS Indicator midThis 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.

So, first, check your tire pressures! But to truly understand this warning light, click here! There is so much more to know.

Slip or Stability Control Indicator Symbol

Slip warning midThe 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.

Again, it will flash when its doing its job, despite the look of a skidding car! So, to fully understand this warning light and related lights that may indicate a system fault, click here.

Reduced Engine Power Indicator

Reduced power midThis 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.

The fault is likely in an electronic system, and one vehicle maker suggests stopping the vehicle and restarting it after 10 seconds. This may reset the system and thus resolve the issue. If this does not work, see your dealer or authorized service center as soon as possible.

ESP/BAS

ESP BAS indicator midThis 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.

Primarily, the light indicates a problem with one or both systems, so click here to learn more.

Key Fob Indicator

Key fob midThis 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.

A flashing red Electronic Key symbol shown indicates that the key is not detected. If the Key is in the vehicle, its internal battery is likely dead and needs to be replaced. The same Electronic Key symbol shown in green indicates that the key is found and the vehicle can be started.

There are many, many more versions of this warning light and many more warning lights that use the image of a key. So please click here to learn more.

Intelligent Brake Assist Off Indicator

IBA off midThis 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.

Loose Gas Cap

Check gas cap mid 2This 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.

Park Assist Symbol

Park assist midThese 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!

Washer fluid

Low washer fluid midThis 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.

AFS Off

AFS off midThe 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.
