I've been driving a Mercedes for several years and have encountered a few embarrassing situations where it wouldn't start. The most common reason is an aging battery, especially in winter when the low temperature causes insufficient power - turning the key gets no response. Or it could be a starter motor issue, making clicking sounds but the engine won't turn over. My C-Class got stuck in a shopping mall parking lot for half an hour because of this last time. Additionally, Mercedes' smart key system is prone to problems - a dead key battery or sensor failure can render the start button useless, so it's good to keep spare batteries ready. There are also electronic system issues, like false sensor readings or software errors locking the startup program. Preventive measures are quite simple: check battery voltage monthly, take the car for a spin if it's been parked too long, and avoid prolonged inactivity. If all else fails, call roadside assistance or a professional technician - safety first.

What should you do when driving a motor vehicle on wet roads?

Maintain a longer distance from the vehicle in front. A longer following distance can reduce the impact of water spray from the front vehicle's tires on your visibility. Control the steering smoothly. In case of heavy rain, stop the vehicle immediately. After driving through a waterlogged area, perform several light brake applications to dry the brake pads.
