How to Operate the Lights in an Automatic Transmission Car?

[LeAlessandra]

Turn the light switch to the right twice to turn on the headlights. The original car's high and low beams cannot be turned on simultaneously, meaning you can switch between high and low beams. The toggle lever is located on the lower left side of the steering wheel; move it up and down to switch between high and low beams. Pull the light switch up one notch to turn on the front fog lights. Pull the light switch up two notches to turn on the rear fog lights.

When I first started driving an automatic, I was also confused about the light controls. It's actually the stalk on the left side of the steering wheel. Push it forward for high beams, pull it back to flash your lights at oncoming traffic. The rotary knob's leftmost position turns lights off, one click turns on parking lights, and another click activates low beams. Fog lights usually have a separate button near the instrument panel - remember to turn on low beams first to enable them. When entering tunnels at night, turn on your lights 2-3 seconds in advance. I always keep my left hand ready on the stalk. Oh, and remember to turn off auto headlights after shutting off the engine to avoid draining the battery. Developing a habit of checking indicator lights on the dashboard before exiting is the most reliable approach.

For girls driving automatic cars, just remember these tips: After starting the car, turn the light knob to AUTO mode to free your hands – the headlights will automatically turn on when it gets dark. If you need to manually turn on the fog lights, there's a button with a fog droplet symbol on the left side of the dashboard; press it and the red light will illuminate in rainy weather. To alert the car in front, gently lift the stalk to flash the lights – super handy! For temporary parking by the roadside, turn on the hazard lights; the triangular red button is in the most prominent position on the center console. The key point is to turn off the fog lights immediately after use, otherwise the car will alarm the next time you start it – don't ask me how I know...

Operating lights focuses on safety control. When driving at night, first turn the knob to the low beam position, and switch to low beam 150 meters before meeting another vehicle. On highways, using high beams should correspond with speed; when exceeding 110 km/h, increase the illumination distance. In rainy or foggy conditions, turning on front and rear fog lights is more conspicuous than hazard lights, and it's mandatory by regulations when visibility is less than 100 meters. Pay special attention to the automatic high beam function in new models, as it may misjudge oncoming motorcycle lights on rural roads—I usually manually override it for better safety.

From an electrical principle perspective, the automatic transmission vehicle lights are managed by the BCM (Body Control Module). The rotary switch sends signals to the control unit, which then triggers the corresponding lights through relays. For example, turning on the fog lights requires the headlights to be powered first, which is a circuit interlock design. Automatic headlights rely on a photoresistor sensor located at the base of the rearview mirror on the windshield, activating in places like underground garages or on cloudy days. Modern smart vehicle models can even combine GPS tunnel positioning to turn on the lights in advance. However, mechanical switches remain the most reliable backup solution.
