Mercedes-Benz Dashboard Warning Lights
What do the Mercedes-Benz warning lights mean? Take a look at the most common Mercedes dashboard lights and what they mean.
Check Engine Light This is the engine malfunction warning light. This light comes on when the On-Board Diagnostic (OBD) system indicates a problem with how the engine runs. It could be something as simple as a loose gas cap or even a transmission problem. Use an OBD-II scanner to read the fault codes via the OBD-II port located under the dashboard on the driver’s side. Don’t ignore the check engine light, or your vehicle may go into limp mode. |
Airbag Warning Light |
Tire Pressure Monitoring System. Check the tire pressure and add air if one or more tires have low tire pressure. Find a space place to park and check that you don’t have a flat tire. Check tire pressure and add air to any tires that may become low. The recommended tire pressure is found on a black sticker on the driver’s door frame or behind the fuel gas cap door. If the light remains on, the system has malfunctioned, or one of the sensors in your rim has failed. |
Battery Warning Light |
This light is reminding you that you or your passengers need to use the seat belt. |
This warning light means that you are low on Diesel Exhaust Fluid or also known as DEF. Add DEF fluid as soon as possible. The AdBlue indicator is found in 2010 and newer Mercedes-Benz models with BlueTec technology. The main purpose of the AdBlue fluid is to remove the harmful particles from the exhaust. |
The distance warning lamp will light up if you are getting too close to the vehicle in front of you. Distance warning may come to stay if there is a problem with the autonomous braking function COLLISION PREVENTION ASSIST PLUS. |
This is the warning light for the electronic stability control. Try restarting the car, turning the steering wheel all the way to the left and then all the way to the right. In some cases, this procedure will reset the ESP warning. This warning may come on if you recently replaced the battery. It can also come on if you have a bad wheel speed sensor. If the light says ESP Off or ESP Off, it could be because you have pressed the ESP button on the dashboard. |
The light bulb symbol means that one or more of the light bulbs is burned out. You should see a warning message in the center of the instrument cluster. If all your lights work, but you are still getting this warning, it could be due to one of the bulbs having been replaced with a bulb that has the wrong wattage. |
It means that you are running out of fuel. Stop at the closest gas station and add fuel. |
Brake Light |
This warning light means the Anti Lock Brake System is not working. This doesn’t mean your brakes are not functioning. It means the vehicle may skid or take longer to bring to a complete stop. If the ABS fails, ESP (Electronic Stability Program), BAS (Brake Assist), and EBD (Electronic Brake-force Distribution) will most likely be deactivated as well. All these systems depend on the ABS to function. Common problems that trigger Mercedes-Benz ABS light are brake light switch, ABS wheel speed sensor, and defective clock spring. Use a multi-system OBD-II scanner to read fault codes from the ABS module. |
The spiral symbol that looks like a spring is the glow plug light. When you first turn on the ignition on diesel models, you need to wait a few seconds for the glow plug to turn off. Once the glow plug light turns off, you are good to start the engine. The glow plugs are installed to warm up the cylinders so that you can easily start the engine. |
Power Steering |
Engine Overheating |
Attention Assist |
