If you see illuminated Mercedes-Benz dashboard warning lights during your Cook County commute, your initial reaction might be one of concern, yet these symbols aren’t always an indication that your vehicle is in need of repair. Sometimes, they can indicate your Mercedes-Benz diesel engine is warming up, or you may be getting an alert from your ATTENTION ASSIST® driver attention monitor that it’s time to take a break from driving. In other cases, it may be a simple fix, such as topping off your gas tank or correcting your tire pressure. Learn more about some of the most common Mercedes-Benz dashboard warning lights and whether or not they require a visit to the Mercedes-Benz of Chicago service center today!
Mercedes-Benz Dashboard Warning Lights Explained
ABS Light
Icon: Circle with “ABS” in the center and one curved line on either side
Meaning: If you see this symbol, the Anti-Lock Brake System, as well as ESP®, BAS®, Electronic Brake Force Distribution, and Hill-Start Assist, have been deactivated. While the system won’t correct vehicle instability or help with emergency braking, you will be able to slow and stop your Mercedes-Benz.
Airbag Light
Icon: Person with airbag deployed in front of them
Meaning: There is a malfunction in the SRS (Supplemental Restraint System). The airbag may not deploy in the event of an accident. To protect yourself and your passengers, you’ll want to seek service immediately.
ATTENTION ASSIST® Light
Icon: Steaming cup on a saucer
Meaning: The ATTENTION ASSIST® driver attention monitor lets you know when you’re losing focus while driving on the streets of Chicago. When this symbol illuminates, it’s time to pull over and take a break.
Battery Light
Icon: Battery with a plus and minus sign
Meaning: For some reason, your vehicle’s battery isn’t charging correctly. This could be due to a malfunctioning alternator, poly-v belt, or a problem with the electrical system.
Brake Wear Light
Icon: Circle with a dotted line on either side
Meaning: Your brake pads and/or brake rotors are nearing the end of their life and are due for a replacement. Schedule a brake replacement ASAP to avoid brake failure or vehicle damage.
Check Engine Light
Icon: Engine
Meaning: The check engine light can signify an issue with the engine itself, fuel or fuel injection systems, ignition, or exhaust. High emissions could have also caused the engine to enter emergency mode.
Coolant Light
Icon: Red temperature gauge over fluid lines
Meaning: The coolant level may be too low, or the temperature gauge may be faulty. Monitor the temperature, and pull over immediately if the coolant exceeds 248 degrees Fahrenheit. If you continue to drive your vehicle while it’s running at such high temps, you could damage the engine.
DEF/AdBlue® Indicator
Icon: Two rows of vertical dots on top of a horizontal funnel
Meaning: The Diesel Exhaust Fluid (DEF) volume is running low. This fluid is critical for your emissions system as it’s used to cause a catalytic reaction to remove particles from the exhaust.
ESC or ESP® Light
Icon: Car with two skid marks
Meaning: Electronic Stability Control (previously known as ESP®, Electronic Stability Program) has been deactivated. If your vehicle goes into a skid, this feature will not intervene.
Glow Plug Light
Icon: Yellow coil
Meaning: Diesel engines, such as the one available in the Sprinter, use glow plugs to heat the cylinders inside. When this light is on, the glow plugs are in the process of heating the cylinders.
Seat Belt Light
Icon: Person with seat belt
Meaning: Either the driver or front passenger (or both), have not yet fastened their seat belt. Once the vehicle exceeds 15 MPH, the warning light will be paired with an audio cue.
Steering Wheel Light
Icon: Steering wheel with an exclamation point next to it
Meaning: The power steering isn’t working, so you’ll need to be more forceful when turning the wheel.
Tire Pressure Light
Icon: Flat tire
Meaning: Your tire pressure has dropped in your tires (either one or several), and they don’t have a sufficient amount of air in them. Pullover to a safe place, and top off the air in the tires.
