Once you have successfully parked your car in a designated spot, the next step is to properly position it for optimal safety and functionality. This may seem like a simple task, but it requires precision and attention to detail to ensure that your car is in the best position for driving and maneuvering.

In this step, we will discuss the key aspects of positioning your car, including the correct placement within the parking spot, adjusting the mirrors, and checking for any blind spots.

1. Centering the car in the parking spot

The first and most important aspect of positioning your car is to ensure that it is centered within the parking spot. Start by aligning your car with the curb or other cars parked nearby. Use your mirrors and judge the distance between your car and the surrounding objects to make sure it is centered.

If your car has a back-up camera, use it to help align the car in the center. Keep in mind that it is always better to be slightly further from the curb or other cars than too close, to avoid any potential scrapes or damages.

2. Adjusting the mirrors

Before driving, it is important to make sure that all of your mirrors are properly adjusted to maximize your visibility. Your side mirrors should be positioned so that you can see the sides of your car in the outermost edges, while also giving you a clear view of the road behind you.

Your rearview mirror should be adjusted so that you have a clear view of the road behind you as well as your backseat. This is important for maintaining situational awareness while driving.

3. Checking for blind spots

Blind spots are areas around your car that are not visible in your mirrors, and can potentially cause accidents if not checked properly. To avoid this, always take a moment to physically turn your head and check your blind spots before changing lanes or making a turn.

This step is especially important when driving larger vehicles, such as trucks or SUVs, as they have bigger blind spots. Utilize your side mirrors to help you check for blind spots, but always physically turn your head to ensure complete visibility.

Find the Headlight Axis

Step 3: Find the Headlight Axis

After understanding the basic components of a headlight and performing initial checks, the next step in headlight maintenance is to find the headlight axis. The headlight axis determines the direction in which the light beam is projected and plays a crucial role in ensuring proper illumination while driving.

To find the headlight axis, follow these steps:

  • Park the vehicle on a level surface: It is important to have the car parked on a level surface to get an accurate measurement of the headlight axis. This will ensure that the light beam is projected in a straight line and not at an angle.
  • Measure the distance between the headlight and the ground: Using a tape measure, measure the distance between the center of the headlight and the ground. Note down this measurement as it will be used later in the process.
  • Locate the position of the center of the headlight: With the help of your car’s manual, locate the exact position of the center of the headlight. This may vary depending on the make and model of your car. Use a marker or tape to mark this position on the ground.
  • Mark the headlight axis: Using the measurement taken in step 2, make a mark on the wall or garage door at the same height as the headlight’s center. This will serve as a reference point to determine the headlight axis.
  • Turn on the headlights: Turn on the headlights to their low beam setting. The light beam should project straight ahead onto the wall or garage door.
  • Adjust the headlight axis: Using the adjustment screws on the headlight assembly, adjust the headlight until the light beam is aligned with the previously marked point on the wall or garage door. This will ensure that the headlight axis is aligned with the center of the headlight.
  • Repeat the process for the other headlight: Once the headlight axis is determined for one headlight, repeat the same process for the other headlight. It is essential to have both headlights aligned properly for optimal visibility while driving.
