Where is the headlight adjustment for the 2016 LaCrosse?
2 Answers
The headlight height adjustment for the Buick LaCrosse is located on the exterior light control device to the left of the steering wheel. This function allows the headlight height to be adjusted to match the vehicle load. The low beam headlights must be turned on to adjust the headlight height. Buick LaCrosse headlight adjustment method: When the ignition switch is in the "ON" position and the headlights are turned on, the headlight beam control will take effect, allowing the headlight axis to be adjusted according to driving conditions. If driving without a heavy load, luggage, or on a flat road, select the normal position "0". If the number of passengers and the load or luggage in the vehicle change, the headlight axis will be higher than the normal position. To adjust to the appropriate beam height, turn the corresponding switch. The higher the number marked on the switch, the lower the headlight axis will be. Precautions for using vehicle lights: When a motor vehicle passes through an intersection controlled by traffic signals and turns left, the turn signal should be activated, and the low beam should be turned on when driving at night. During periods when streetlights are on, or when driving in conditions of low visibility such as fog, rain, snow, dust, or hail, the headlights, position lights, and rear position lights should be turned on. When a following vehicle is driving close to the vehicle in front in the same direction, the high beam should not be used.
I remember driving a 2016 LaCrosse before, and the headlight adjustment knob was located in the lighting control area on the driver's left side. There was a rotatable knob there, and a gentle turn would adjust the beam height up or down. This position is very convenient, easily reachable without needing to consult the manual or open a screen. If the beam is too high or too low, it can affect nighttime driving safety, making it hard to see the road or blinding oncoming traffic. It's advisable to check regularly to ensure the angle is appropriate, especially after changing tires or when the vehicle's height changes due to loading, to prevent accidents. During routine maintenance, it's also crucial to quickly check if the light sockets are loose.
