Mercedes-Benz Dashboard Warning Symbols and Meanings Explained

Gauge cluster inside 2020 GLE SUV

An illuminated warning light is never a welcome sight on your dashboard, but not all warning lights are cause for panic. While some warning lights aren’t dire, others symbols like the ABS or check engine light require more immediate attention by Laguna Beach drivers. What’s more, there are other Mercedes-Benz dashboard symbols that refer to brand-exclusive features like ATTENTION ASSIST®.

Common Mercedes-Benz Dashboard Symbols & Meanings

ABS Light

Icon: Circle with “ABS” in the center and one curved line on either side

Meaning: The Anti-Lock Brake System is deactivated. Once this system is off, ESP®, BAS®, Electronic Brake Force Distribution, and Hill-Start Assist will deactivate as well. You’ll be able to slow and stop on the Corona Del Mar and Huntington Beach roads, but you won’t get the response of emergency braking or traction control.

ATTENTION ASSIST® Light

Icon: Steaming cup on a saucer

Meaning: Often accompanied by a warning tone, the ATTENTION ASSIST® monitors your driving behaviors for signs of sleepiness. This alert means it may no longer be safe for you to drive your vehicle on the streets of Costa Mesa.

Brake Wear Light

Icon: Circle with a dotted line on either side

Meaning: If this symbol is present, it’s time to replace the brake pads and/or brake rotors. You’ll want to schedule service immediately to avoid vehicle damage and safety hazards.

Battery Light

Icon: Battery with a plus and minus sign

Meaning: This means the battery isn’t charging properly. This could be caused by a problem with the electrical system or a malfunctioning alternator or poly-v belt.

Check Engine Light

Icon: Engine

Meaning: The check engine light can signify a variety of issues, including problems with the engine, fuel or fuel injection systems, ignition, or exhaust. The engine can also enter into emergency mode due to high emissions.

Coolant Light

Icon: Red coolant light

Meaning: The coolant level may be too low, or you may have a faulty temperature gauge.

ESC or ESP Light

Icon: Tilting car with wavy lines behind it

Meaning: Electronic Stability Control (previously known as ESP®, Electronic Stability Program) has been deactivated. If you’re driving and this appears inside a yellow triangle, that means traction control has intervened due to wheels spinning or a skid risk.

Glow Plug Light

Icon: Yellow coil

Meaning: Glow plugs heat the cylinders inside a diesel engine. When this light is on, the glow plugs are in the process of heating the cylinders.

Light Bulb

Icon: Light bulb

Meaning: A lightbulb has failed.

Steering Wheel Light

Icon: Steering wheel with an exclamation point next to it

Meaning: The power steering isn’t working. You’ll need to be forceful in operating the steering wheel until it can be repaired.
