What does 4MATIC stop running mean
2 Answers
4MATIC stop running means the four-wheel drive technology has stopped working. The following is a detailed introduction to the 4MATIC technology: 1. Working method: The 4MATIC technology utilizes the ABS braking force automatic distribution function to achieve differential limitation. When a wheel of this full-time four-wheel drive vehicle slips, the onboard computer uses ABS to brake the slipping wheel to limit idling. As a result, the differential can transfer the power delivered to the slipping wheel to other non-slipping wheels. 2. Features: The 4MATIC full four-wheel drive system is compact and lightweight, while also having optimized performance in terms of friction. Compared to other full four-wheel drive systems, its advantages are quite obvious, with outstanding performance in weight, fuel economy, comfort, and safety in passive states.
When the 4MATIC stops functioning, it means there's a failure in Mercedes' all-wheel-drive system, and it can't operate normally. While driving, I might suddenly notice the all-wheel-drive warning light on the dashboard, usually yellow or red, which can be quite alarming. The car may automatically switch to rear-wheel drive, making it feel more slippery and unstable, especially in rain, snow, or muddy conditions, increasing the risk of skidding or even losing control. The causes can vary—it might be sensors on the wheels clogged with mud, mechanical wear in the drivetrain, or a burnt-out electronic control unit. In such cases, I should immediately slow down, pull over, and avoid pushing the car further. Find a safe place to inspect it or call for a tow to a repair shop. Diagnosing the issue requires an OBD scanner to retrieve specific error codes, after which professionals can handle the repair. Regular maintenance, like cleaning undercarriage components, can help avoid these problems and ensure driving safety.
