SEAT Warning Lights

Seeing a warning-light pop-up on your SEAT dashboard can be frightening, especially if you don’t know what it means. SEAT warning lights can be split into three main categories - Red warning lights, which require urgent attention, orange warning lights that require action, and green warning lights that indicate when a system is active. 

If you see a red or orange car warning light symbol, you must bring your car in for a service as soon as possible.

Red SEAT car warning lights 

Red warning lights indicate a severe fault with your vehicle and require urgent attention. Here are some of the most common red warning lights that you may see on your vehicle dashboard. 

The red warning triangle light

The red warning light triangle will illuminate if there is an information message on your SEAT console that needs to be read urgently. Read the message and then take the appropriate action. 

The parking brake warning light

The parking brake warning light will come on to indicate that your handbrake is on. If the light remains on when your handbrake is released, then this could mean a fault within your handbrake system, and you should have your vehicle serviced, immediately, in case it fails. 

The brake system warning light

The brake system warning light will illuminate if your brake fluid level is low or there is a fault in your braking system. Stop your vehicle immediately to check your brake fluid levels. If your levels are low, then they will need to be topped up before continuing your journey. If your levels are normal, but the light is illuminated, then you need to book your car in for a service as there could be a fault in your braking system. 

The steering fault light

A red steering fault light indicates that there is a severe fault with your steering. If you see this light appear while you are driving, then you should pull over immediately and seek assistance. 

The press foot brake warning light

A red foot brake warning light will illuminate on your SEAT dashboard if your Adaptive Cruise Control has detected that there is an insufficient braking distance between you and the vehicle in front. You should apply your footbrake to increase your braking distance. 

The AdBlue light

A red AdBlue warning light will appear if your AdBlue level is too low for your engine to restart. If this light appears while you are driving, then you may be unable to re-start your car, so drive yourself to full the AdBlue tank immediately. If the red AdBlue light also appears with a spanner, then this indicates that there is a fault in your AdBlue system and you should take your vehicle in for a service as you may not be able to restart it. 

The gearbox warning light

If a red gearbox warning light appears on your SEAT dashboard, then this is an indication that there is a severe fault with your clutch or gearbox. This warning light is usually accompanied by a message which will provide you with more information about the error. 

The engine cooling light

A red engine cooling light signifies that the engine of your car is overheating. If the light remains on steadily, then this usually means that your engine coolant levels are low. If the light is flashing, then this means that there is a fault in the engine cooling system. Do not drive your vehicle if this light is on as it can permanently damage your engine. 

The oil pressure warning light

The oil pressure warning light will illuminate if our engine oil levels are low or there is a fault with your engine oil system. Pullover, as soon as it is safe to do so and check your engine oil levels. If they are reasonable, then it is likely that there is a fault with your system and so you will need to call for roadside assistance. 

The battery light

The red battery warning light will flash up momentarily when you first start your engine, but should then go off. If this red warning light remains on when you are driving, then it indicates that your alternator is not charging your battery. Without charge, you may be unable to restart your car, so you must drive to a garage immediately and have your battery serviced. 


Orange SEAT dashboard warning lights

Orange dashboard warning lights indicate that there is something that requires your attention but is not as dangerous as a red warning light. Some of the most common SEAT orange warning lights are: 


The service interval warning light 

Service intervals are predefined within your car, and so the service interval warning light will illuminate when your vehicle has reached a specific mileage and is due for a service. You must try to have your SEAT regularly serviced to keep it in optimum working order.  

The ice warning light

The ice warning light will illuminate when temperatures are less than 4°C to notify you that road conditions may be slippery. 

The orange gearbox fault light

An orange gearbox fault light usually means that you can continue to drive your vehicle, but that a fault has been detected in the system. The warning light will be accompanied by a message to help you narrow down the problem. You should bring your SEAT in for a service as soon as possible before the fault worsens. 

The orange engine oil level light 

The orange engine oil level light will illuminate continuously to let you know that your engine oil levels are low. If the light is flashing, then this is because there is a fault with the sensor. Check your SEAT engine oil levels and top them up accordingly. 

The lightbulb warning light

The lightbulb warning light will appear if one or more of your driving lights are no longer working. You should pull over when it is safe to do so and check your bulbs to see which ones have blown. Replace faulty bulbs as soon as possible. 

The airbag warning light

An orange airbag warning light will illuminate if a fault has been detected in your airbag system. You should have your car looked at as soon as possible, as otherwise you may not be protected if you crash. 

The water in the diesel water light

If you have a diesel SEAT, then the water in the diesel warning light will show if water has been detected in your diesel fuel tank. Water in your diesel can cause serious engine issues, and so it is vital to have any contaminated fuel drained and replaced. 

The tyre pressure monitoring warning light 

Newer SEAT vehicles are now fitted with tyre pressure sensors that will alert you when your tyre pressure is low. If this light illuminates, then you need to check your tyre pressures. If your tyre pressures are healthy, then this light could indicate an imbalance in your vehicle, a damaged tyre or a fault with the sensor.  

The diesel particulate filter light 

The DPF filter light will come on if your DPF filter needs cleaning. Sometimes the light will go off on its own if the vehicle is driven at a speed between 30 and 70 mph, however, if the light remains on after driving then this indicates that the filter needs to be manually cleaned or replaced. 

The EPC warning light

The Electronic Power Control light will light up if a problem has been detected with your electrics. EPC fault codes can be read by a mechanic using a VAG machine. 

The glow plugs warning light

The glow plug warning light will come on when you first start your vehicle but should then go off. It is not uncommon for the light to stay on for longer during the winter. If, however, the light is flashing, then this means that a fault has been detected and you should have your fault code read by a mechanic. 

The engine warning light

If your engine warning light is illuminated, then this means that there is a fault in the engine management and emissions control system. If the light is flashing, then this indicates that the error is more dangerous. Whether the engine light is flashing or steady, you should bring your car in for a service as soon as possible.  

The Traction Control warning light

The Traction Control (TC) warning light will flash on your dashboard when your traction control kicks in. If the light remains steady-on then this could signify a fault in the system. 

The ESC warning light

The Electronic Stability Control warning light will flash when the ESC system is active and will remain steady-on if a fault has been detected in the system. If the light remains steady on then, you should be mindful that your car may be less stable and bring your car in for a service.

The orange AdBlue light 

An orange AdBlue light indicates that your AdBlue level is low and will usually be accompanied by a mileage notification. If a spanner accompanies the AdBlue light, then this means that a fault has been detected in your AdBlue system or that unsuitable AdBlue fluid has been used. 

The orange steering fault light

An orange steering fault light usually means that your steering column is jammed or your steering has limited operation. Try restarting your car to see if the fault clears. If the fault remains then do not drive your car and seek assistance. 

The ABS warning light

If your ABS warning light comes on while you are driving, then this means that an ABS fault has been detected and your ABS may not work. You should bring your car in for a service as soon as possible as your car could be at an increased risk of skidding. 

The orange warning triangle light

The orange warning triangle light will illuminate on your dashboard to indicate that an important, but not critical, message needs to be read. Read the message, and the light should disappear. 


​​Green SEAT lights

​Green SEAT lights are indicators rather than warning lights and illuminate to show when certain systems are active. Some of the green lights that you may see include; 

The Engine Auto-Stop light

This light will illuminate if Engine Auto-Stop is switched on and the engine has been stopped. 

The cruise control light

The cruise control light will illuminate green if cruise control has been turned on.
