The turn signals on a Mercedes-Benz are located in two positions: inside the front headlights and on the exterior of the rearview mirrors. The turn signal is an important indicator light that is activated when the vehicle is turning to alert surrounding vehicles and pedestrians. The turn signal bulbs use xenon tubes and are controlled by a microcontroller circuit, flashing alternately left and right without interruption. The left-hand stalk switch on the steering wheel controls the vehicle's left and right turn signals. Direction: Pushing the stalk up activates the right turn signal (clockwise direction, turning the steering wheel to the right); pulling the stalk down activates the left turn signal (counterclockwise direction, turning the steering wheel to the left). Turn signal usage scenarios: When overtaking, first activate the left turn signal, then the right turn signal after overtaking. When entering a highway, use the left turn signal. When exiting a highway, always turn right. No signal is needed when entering a roundabout, but the right turn signal should be used when exiting. Use the right turn signal when pulling over to park. When leaving the roadside, always turn left, so use the left turn signal. U-turns generally involve turning left, so use the left turn signal. Use the left turn signal when changing lanes to the left, and the right turn signal when changing lanes to the right. When preparing to turn, activate the turn signal in advance to give following drivers time to react.
