Introduction to the Mercedes-Benz Active Service System (ASSYST, ASSYST PLUS, ASSYST at fixed intervals) Service indicator lights
Since 1997, most Mercedes-Benz vehicles have been equipped with an electronic computer system linked to the dashboard that tells drivers when the engine needs service. A wrench symbol will appear on the instrument panel, including the message "Service A", "Service B" and, in the case of an ASSYST PLUS system, up to "Service H". These messages indicate which service package is required, with "Service A" being a simpler and less labor intensive service package than "Service B", and so on. An odometer will be shown below the message showing how many miles are left until service. If the driver neglects the service light, they risk damaging the engine or, worse, being stranded on the side of the road or having an accident.
For these reasons, performing all scheduled and recommended maintenance on your vehicle is essential to keep it running properly so you can avoid the many untimely, inconvenient, and possibly costly repairs that result from negligence. Luckily, the days of racking your brains and running diagnostics to find the service light trigger are over. The Mercedes-Benz ASSYST Service Reminder System is an on-board computer system that alerts owners when service is required so they can resolve the issue quickly and without hassle.
At its most basic level, the system actively monitors wear and tear on the engine and other vehicle components using special sensors and algorithms that help determine how many miles to drive between service intervals. It depends on many factors, including driving habits and environmental factors. As soon as the ASSYST service reminder system is triggered, the driver knows to schedule an appointment to take the vehicle to service.
How the Mercedes-Benz ASSYST Service Reminder System Works and What to Expect
The sole function of the Mercedes-Benz ASSYST service reminder system is to remind the driver to change the oil and other scheduled maintenance as specified in the standard maintenance schedule. The computer system uses sensors and algorithms to monitor certain vehicle components such as oil life, brake pads, brake fluid, spark plugs, and other critical engine components. The car will display the number of miles to or the date a certain service is due on the dashboard when the car is turned on.
The system is set to trigger at 9,000 to 15,500 miles, 12 to 24 months, or whichever comes first. Once the system has been triggered and the mileage and/or time countdown has completed, a message is displayed telling the driver to "DO SERVICE", informing the driver that it is time to make an appointment for immediate vehicle service. . If your Mercedes-Benz service indicator tells you "GET SERVICED" or the vehicle hasn't been serviced in one to two years as recommended depending on the year and model, you need to get your vehicle in for service as soon as possible. as much as possible.
In addition, the Mercedes-Benz ASSYST service reminder system is algorithm-driven and takes into account the difference between light and extreme driving conditions, cargo weight, towing or weather conditions - important variables that affect oil life. Even though the car controls the engine itself, it is still very important to know the driving conditions throughout the year and, if necessary, to consult a professional to determine the need for servicing your car depending on your specific, most frequent driving conditions.
Below is a helpful chart that can give you an idea of how often you may need to change the oil in a modern car (older cars often require more frequent oil changes):
