Step 1: Visual Inspection
  • Tools Required: Clean microfiber cloth, flashlight.
  • Instructions:
    1. Inspect the front-facing cameras and sensors for dirt, grime, and obstructions.
    2. Clean the camera lenses and sensors with a microfiber cloth.
    3. Check for any physical damage to the cameras or sensors.
Step 2: Software Update Check
  • Tools Required: Tesla Mobile App or vehicle touchscreen.

Step 3: Calibration Check
  • Tools Required: None.
  • Instructions:
    1. Drive the vehicle in a well-marked lane at highway speeds for at least 15 minutes.
    2. Observe if the lane-keeping assist starts to function properly.

Step 4: Check Vehicle Alignment
  • Tools Required: Alignment tool (if available), tape measure.
  • Instructions:
    1. Find a flat, level surface.
    2. Measure the distance between the front and rear tires on both sides to ensure they are aligned.

Step 5: Tire Pressure Check
  • Tools Required: Tire pressure gauge.
  • Instructions:
    1. Check the tire pressure on all four tires.
    2. Compare the readings to the recommended tire pressure found on the driver’s side door jamb.
    3. Inflate or deflate tires as necessary.
