For a dirty radar sensor on a Mercedes, simply wipe the probe. Here are the relevant details: Probe: When the driver sees this alert, they can use a tissue or towel to wipe all the probes. It might be mud, water, or plastic stuck to the probe, and cleaning it will resolve the issue. Main Function: The vehicle's radar sensor should be cleaned promptly. This sensor primarily functions by emitting and receiving ultrasonic signals, which are then input into the main unit and displayed on the screen. If there is dirt on the probe, it can cause detection abnormalities or even incorrect signals, potentially affecting the driver's judgment and leading to accidents.

Having driven Mercedes for so many years, I've learned to be extra careful when cleaning the radar sensors. They're usually located on the front and rear bumpers - those small circular or square black modules. I always check them during car washes. If I notice mud splatters or bird droppings covering them, I gently wipe with a soft sponge dipped in lukewarm water. Never use a high-pressure washer or scrub with rough cloths - these components are quite delicate. By the way, the small side sensors are particularly prone to dirt buildup and need attention too, otherwise the lane change assist might give false alarms, which can be quite startling on highways. If you're unsure about their locations, your owner's manual is the perfect reference - it clearly marks all sensor positions.

Can the snow mode be left on all the time?

snow mode should not be left on for extended periods. Definition of snow mode: Snow mode is a vehicle's winter driving function. When activated, it provides more stable driving performance on icy or snowy roads. Snow mode mechanism: Snow mode is managed by traditional mechanical systems, with computer-controlled programming that allows the transmission to start in second or third gear. This ensures smoother vehicle operation with lower torque output, reducing the likelihood of tire slippage on slippery snow surfaces. Typically achieved through electronic throttle control and transmission settings, activating snow mode reduces engine power output compared to normal conditions, making wheel slippage less likely.

What is the standard lane width?

Standard lane width: For a four-lane bidirectional road, it is 2*7.5 meters; for a six-lane bidirectional road, it is 2*11.25 meters; for an eight-lane bidirectional road, it is 2*15 meters. The country has standards for the width of each motor vehicle lane on highways. For multi-lane highways above grade three, the width of each motor vehicle lane is 3.5~3.75 meters. There is no unified standard for the central median, which is determined according to local conditions. A simple cement central median is one meter wide. If it is a central green median, there is no unified standard for the width. Some 'image projects' can have medians as wide as several tens of meters.
