UVs. or utility vehicles. are commonly oversized automobiles intended for diverse tasks. These may range from carrying hefty loads and shuttling numerous individuals to navigating challenging landscapes. Included in the category of UVs are SUVs. pickups. trucks. and lorries.

Yes, the auto engine off feature, often referred to as "start-stop" technology, does save gas by automatically shutting off the engine when a vehicle is at a standstill, like at traffic lights or in heavy traffic, and restarting it when the driver presses the accelerator. This prevents fuel from being wasted while the car is idle. It's particularly effective in urban settings where stop-and-go driving is common. Studies have shown that this technology can improve fuel efficiency by about 3-10%, depending on driving conditions. However, the actual savings depend on the specific vehicle and driving patterns. While some drivers find the start-stop function unnoticeable, others may find it intrusive. Nevertheless, in terms of reducing fuel consumption and emissions, start-stop technology is a beneficial feature.
The Check Engine Light (CEL) on a Mercedes, like in most modern vehicles, is designed to illuminate when the onboard diagnostics system (OBD-II) detects a malfunction or irregularity in the engine or emissions system. While minor issues might cause the light to turn off once the problem is resolved (for example, a loose gas cap), most of the time, the CEL will not reset itself immediately after a fault is corrected. It usually requires either a certain number of driving cycles without the fault recurring for the system to automatically turn off the light or the use of an OBD-II scanner to manually reset the system. If the light came on due to a serious issue, simply correcting the fault will not reset the light; diagnostic equipment will likely be needed to clear the fault codes from the system. It is important to address CEL warnings promptly to avoid potential damage to your vehicle. If the light remains on, it's advisable to have a professional diagnose and rectify the issue.
