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. |
DEF/AdBlue Indicator
 | DEF/AdBlue Indicator The Diesel Exhaust Fluid (DEF) is low. The fluid creates a catalytic reaction that removes particles from the exhaust. |
Seat Belt Indicator
   | Seat Belt Indicator 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. |
Traction Light Off
   | Traction Off Light 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. |
Gas Light
 | Gas 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. |
ABS Light
 | ABS Light ABS (Anti-Lock Brake System) is deactivated due to a malfunction. Â 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 Indicator
   | Brake Wear Indicator The brake pads and/or rotors have reached their wear limit and need to be replaced. |
ESC or ESP Light
 | ESC or ESP Light 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. |
Coolant Light
   | Coolant 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. |
Airbag Light
   | Airbag Light 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. |
Battery Light
   | Battery 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. |
Tire Pressure Light
 | Tire Pressure 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. |
Light Bulb
   | Light Bulb A light bulb has failed. This light may be accompanied with a message on the dashboard stating which specific light is out. |
Brake Light
   |  Brake Light You are driving with the parking brake on. |
Glow Plug
   | Glow Plug 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. |
Steering Wheel
   | Steering Wheel The power steering assistance is faulty. You will need to use more force to steer the vehicle. A warning tone will also sound. |
Attention Assist
 | Attention Assist By continually monitoring a variety of driving behaviors, this Mercedes-Benz innovation can audibly and visually alert the driver if it detects signs of drowsiness on long trips. |
