It’s important to know what the dashboard Mercedes-Benz M-Class warning lights actually mean, though, not least because they can pre-empt a car breakdown or full-on failure, potentially saving you from an expensive repair bill and meaning you stay safer on the road.
Here are the most important Mercedes-Benz M-Class warning lights you should watch out for:
Engine Oil Level or Oil Pressure Warning Light Symbols, indicate that the oil temperature gets too high, the oil level is low or oil pressure too low. STOP driving immediately and turn the engine off. The engine can be severely damaged if oil pressure is lost. Add oil to the engine to bring the level up.
Brake Warning Light symbols, indicate a serious Brake problem, but the light will also be on when the hand, or emergency brake, is engaged. It’s best to get it checked out right away.
Temperature Warning Light Symbol, indicates that the engine temperature is too high. You should stop the vehicle and turned off the engine as quickly as possible. It could mean coolant levels are running low, so check the gauge on the side of the coolant tank under the bonnet and top up if necessary.
Battery Charge Warning Light Symbols. You should see your battery charge warning light when you first turn your car on, but if it doesn’t go out a few seconds after the engine starts, there could be a problem with your car’s electrical system. This could be to do with a faulty alternator, faulty battery, a bad connection or damaged cabling somewhere in the engine bay.
SRS Air Bag Warning Light Symbols, indicate that a problem exists with one of the many airbags in the automobile, which should be taken to the dealer or authorized service center as soon as possible.
Power Steering Warning Light Symbol, If it is an electronic system, there is a chance it can be “reset”. Pull over as soon as possible and shut down the engine and restart it. If the light does not go out you will need to take the vehicle to your dealer or authorized repair facility. When the Power Steering System fails, the steering could go heavy, meaning more effort will be needed to make the car change direction.
Engine Warning Light Symbol. when your engine warning light is illuminated, often it’ll be accompanied by some unusual symptoms – these could include a lack of power, as the car has gone into ‘safe’ mode to protect itself; an intermittent stuttering as you press the accelerator, caused by a misfire; or another fault which could alter the normal response from the engine. Sometimes this can be down to something as small as a faulty electrical sensor, although sometimes it can be a larger mechanical issue.
Tire Pressure Monitoring System/Flat Tire Monitor Symbols, indicate that the inflation on one of the tires is down 25% or more. If your are at high speed, reduce your speed.
