Overheat
One of the original idiot lights, at least in red, this is the Temperature Warning lights or symbols. The text symbol Hot Coolant Temp (temperature) spells it out plainly. 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.
- But first, is one of these truly your symbol?? If yes, then read on below!
- Otherwise return to our main Picture Symbols page and scan again!
Contact your dealer or authorized service center as soon as possible. But, what’s the deal with the second one below? Blue?
In blue, the symbol, which resembles a thermometer placed in water, indicates that the coolant temperature is below what is needed for optimum performance. If the light blinks red then blue, an electrical malfunction in the cooling system is indicated.
Again, contact your dealer or authorized repair center soon.
Finally, shown in yellow/amber, the symbol of the thermometer alone speaks to fuel having entered the engine oil. Run the engine until warm to allow the fuel to evaporate. Also, avoid running at a high rpm as well.
Note that this unlit symbol may appear inside the temperature gauge and have no function other than to describe the gauge it is sitting in.

And then there are these, which feature a lower case letter “i” in a square. It too is meant to alert the driver to look for a message in the information center, but the message will not involve a serious drivability issue. The manufacturer uses the red triangles for this. It may be seen in

This is the Tire Pressure Monitoring System (
This text version simply says Flat Tire. While this may seem like it would be obvious to a driver, in truth the pressure in a tire can be very, very low and not result in a large change in the handling of some vehicles.
Many manufacturers now add a symbol or information display image that will highlight the tire or tires that are low on air, like the image to the left. Regardless of the symbol seen, the upshot is this: If your are at high speed, reduce your speed. If the tires do not seem to be visually low, it is likely safe to proceed to the nearest service station. The TPMS system will tell you when a tire is low, yes, but one of them leaking quickly, i.e. a single highlighted tire, is a greater danger.
This version features two arrows pointing at a ball in the center. It is most commonly found on a reset button on the dash, if one exists. It can, however, show up on the instrument panel of older vehicles and likely means that the system needs to be reset or could mean that a tire is low as well. Regardless, the tire pressures must be checked for the sake of safety.
This light holds the system’s primary acronym, TPMS. It is a Malfunction Indicator only. If your vehicle is equipped with this additional tell tale and it remains lit, the Tire Pressure Monitoring System is not operating and needs to be checked by a qualified repair facility.
Last but not least, this bit of silliness offers a different twist. It is the Tire Pressure Monitoring System Light Load indicator. It illuminates to confirm that the load setting is selected. It appears in black and white as the same slice of a tire, but with a feather inside. The setting essentially tells the TPMS system to expect lower tire pressures, as there is little loading inside the vehicle.

If any of these lights come on during normal driving, the system is likely malfunctioning and the vehicle should be brought to your dealer or authorized service center as soon as possible. Some manufacturers combine the 
The symbol to the left is a European version of the ABS warning indicator. A skidding vehicle is shown inside the circle and brackets traditionally used to denote ‘brake components’, also seen in the symbol above with the ABS acronym inside.
This version includes the 4×4 designation beneath the more routing ABS indicator in the circle and brackets. This may indicate a problem with the 4- or All-wheel Drive system as well as the ABS System. If this is the case, one or more additional indicators will be present. Have the vehicle checked as soon as possible by a competent shop.
Finally, one manufacturer has opted to have this warning light, ABS ACTIVE, come on when the ABS system is simply doing its job . It does not indicate a fault.
Note that if any of the ABS warning lights are seen with either of these warning lights (right), they indicate a problem with the Brake Force Distribution System.

This is the Brake Trouble Indicator symbol in Canada, and other areas, but has an additional use elsewhere (below). The look of this symbol as well as others involving brakes are supposed to resemble the physical appearance of brakes. They do, but primarily only to people who have had the opportunity to take them apart. The word ‘brake’ may appear at the top of the image.
Finally, the image is used by some manufacturers to indicate a problem with the Regenerative Brake System in electric vehicles (EVs). It may appear in 
And of course someone had to combine the two and then a third as a traditional trouble light, I suppose just to add yet more symbols. The word BRAKE is place below the circle and exclamation point. And above the same indicator plus that with a “P” inside, for parking brake.
This version that includes a thermometer inside the circle is meant to indicate that the brake disk and therefore brake pads are overheated. The car should be pulled over as soon as possible to allow them to cool. If they stay hot, the brake fluid will get hot and boil, at which point brake pressure will be non existent.
