How to adjust the headlight height of XTS?
3 Answers
Methods to adjust the headlight height of XTS: 1. There is a headlight height adjustment button in the lighting control area on the left side of the driver's steering wheel. The driver can adjust it using this scroll wheel button; 2. The scroll wheel is marked with numerical gears, where higher numbers indicate higher headlight positions. The higher the number, the higher the headlight will be raised. Functions of headlights: 1. Turn signals activated when the vehicle needs to turn; 2. High beams and low beams used for illumination; 3. Tail lights that illuminate when braking; 4. Hazard lights used in emergencies such as temporary parking due to vehicle malfunction or in poor visibility conditions during severe weather.
When I was driving the XTS before, I also wondered how to adjust the headlight height. This car's headlights come with automatic adjustment, so you usually don't need to worry about it. However, if you're carrying heavy loads or have replaced the shock absorbers and feel the lights are too low, you can manually adjust them in the central control settings. Start the car, press the settings button on the control panel to enter the lighting menu, and select the headlight height adjustment to see the numerical options. Setting 1 is the brightest but has the shortest range, while setting 3 projects the light the farthest but with lower brightness. I remember last time when I helped a friend move and the trunk was fully loaded, setting 2 was the most suitable. If you feel the adjustment isn't right no matter what you do, it might be a sensor issue. In that case, it's best to take it to a 4S shop for inspection—don't try to adjust the screws on the assembly yourself.
My XTS has been running for over five years, and adjusting the headlight height is actually quite simple. There's a scroll wheel knob on the lower left side of the steering wheel, marked with four positions from 0 to 3. Position 0 is the default setting, and if you want the beams to reach further when driving on the highway at night, just turn it to position 3. However, it's important to note that this manual adjustment is an overlay on top of the automatic adjustment—the system first sets the base height automatically based on the pitch angle of the car's front end. I remember one time when the fog was particularly thick, turning the knob to position 1 along with the fog lights made visibility much clearer. If you find that adjusting the knob has no effect, it's likely due to a faulty relay or poor wiring contact. Although Cadillac's design is convenient, it's still safer to develop the habit of checking the lighting condition every month.
