Mercedes-Benz Dashboard Warning Lights

Ever wonder what is that little dashboard indicator light means?

Below are some of the dashboard indicator lights with descriptions you might see over the course of ownership of your Mercedes-Benz vehicle. The details below are informational and applicable to U.S. Mercedes-Benz models. Please contact our Service Department for assistance at 205-848-7000.

SRS/Airbag Light

SRS Airbag Indicator

There is a malfunction in the SRS (Supplemental Restraint System). This may cause an airbag not to deploy in the event of an accident and is recommended you bring the vehicle to a Mercedes-Benz repair facility as soon as possible.

Coolant Light

Engine Coolant Level Light

If the red coolant light is on you may have a faulty temperature gauge or the coolant level is too low. If the coolant temperature exceeds 248 degrees Fahrenheit (120 degrees Celsius), DO NOT DRIVE the vehicle. The engine could otherwise be damaged.

Light Bulb

Light Bulb Indicator Light

A light bulb has failed. This light may be accompanied with a message on the dashboard stating which specific light is out.

Seat Belt Light

The seat belt warning lamp reminds the driver and front passenger to fasten their seat belts. In addition, if you are driving faster than 15 mph, an audible warning alert will sound.

Oil Light

Engine Oil Indicator

The oil level is low. DO NOT DRIVE the vehicle. The engine could otherwise be damaged.

Parking Brake Light

Parking Brake Light Warning

You are driving with the Parking Brake engaged.

Battery Light

Battery Indicator Warning Light

The battery is not being charged. Possible causes are a faulty alternator, a torn poly-V-belt, or a malfunction in the vehicle electronics.

ABS Light

ABS Warning Indicator

ABS (Anti-Lock Brake System) is deactivated due to a malfunction. ESP (Electronic Stability Program), BAS (Brake Assist), EBD (Electronic Brake force Distribution) and hill start are also deactivated. The brake system continues to function normally, but without the functions listed above.

Brake Wear Light

Brake Wear Indicator

The brake pads and/or rotors have reached their wear limit and need to be replaced.

Tire Pressure Light

Tire Pressure Warning Light

The pressure in one or more of your tires is insufficient or has dropped significantly. Pull over to a safe spot and check all tires.

ESP Off

ESP/ESC Off Indicator

The ESC (or ESP) system has been deactivated. Esc will not stabilize the vehicle if it starts to skid or if a wheel starts to spin. Some vehicles are equipped with an ESP on/off button. Try to reactivate the system or bring to a dealership.

ESP or ESC Light

ESP/ESC Engaged Indicator

Electronic Stability Control (previously known as ESP, Electronic Stability Program) is deactivated. ESC will not stabilize the vehicle if it starts to skid or if a wheel starts to spin. Most vehicles have an ESC on/off button. If this icon should appear inside a yellow triangle, then ESC or traction control has intervened because there is a risk of skidding or at least one wheel has started to spin. Cruise control, if engaged, will be deactivated.

Check Engine Light

Check Engine Light

There may be a malfunction in the engine management system, the fuel injection system, the exhaust system, the ignition system, or the fuel system. The emission values may have been exceeded and the engine may be breaking into emergency mode.

Power Steering Light

Power Steering Light

The power steering assistance is faulty. You will need to use more force to steer the vehicle. A warning tone will also sound.

Fuel Light

Low Fuel Light

Your fuel level could be low or the fuel system pressure is too low. The fuel filler cap is not closed correctly or the fuel system is leaking.

DEF/AdBlue Light

Ad Blue/DEF Warning Light

The Diesel Exhaust Fluid (DEF) is low. The fluid creates a catalytic reaction that removes particles from the exhaust.

Glow Plug Light

Glow Plug Indicator Light

Diesel engines require heat in the cylinders to operate, which is supplied by glow plugs when the engine is cold. This light will be illuminated when the ignition is turned on until the plugs are heated sufficiently to start the engine. The image will look like a coil or loops in amber or yellow.
