Overview

The headlight leveling system in a 2019 Mercedes-Benz C-Class ensures that the headlights are correctly aligned to provide optimal illumination of the road ahead, while also preventing the headlights from dazzling other road users. Adjusting the headlight leveling system typically involves checking and adjusting the headlight alignment, either manually or through the vehicle's settings. Below are the detailed steps to adjust the headlight leveling system on this car model.

Preparation

• Ensure that the vehicle is parked on a level surface.
• Turn off the engine and make sure the headlights are off.
• Check that the tire pressure is correct and the vehicle is not heavily loaded in the trunk or back seats as this can affect headlight alignment.

Manual Adjustment

If your 2019 Mercedes-Benz C-Class model has manual headlight adjustment knobs, follow these steps:

• Open the hood of the vehicle.
• Locate the headlight adjustment screws. These are typically found on the headlight assembly.
• Use an appropriate tool (usually a Phillips screwdriver or a dedicated adjustment tool) to adjust the screws. There is usually one screw for vertical adjustment and another for horizontal adjustment.
• Turn on the headlights and adjust the screws until the light beams align correctly. The top of the beam should be at the same height as the headlight center when projected on a wall or garage door from about 25 feet away.

Automatic or Electronic Adjustment

The 2019 Mercedes-Benz C-Class may also feature an automatic or electronic headlight leveling system, which can be adjusted through the vehicle’s onboard settings:

• Start the vehicle and turn on the headlights.
• Access the vehicle’s settings menu through the central infotainment system or control panel.
• Navigate to the lighting settings or headlight adjustment section.
• Follow the on-screen instructions to adjust the headlight level. This may involve setting the car to a specific mode and manually adjusting the beams via the system interface.
• Test the settings by driving and checking the headlight alignment. Readjust if necessary through the system interface.

Professional Assistance

• If you are unsure about adjusting the headlight leveling system yourself, it is recommended to seek professional assistance.
• Visit a certified Mercedes-Benz service center where trained technicians can use specialized equipment to ensure that your headlights are properly aligned and functioning correctly.

By following these steps, you can ensure that your 2019 Mercedes-Benz C-Class headlights are correctly adjusted, providing enhanced visibility and safety during night driving.
