Solution

1. Preparation

Gather all necessary tools and components.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean Sensors

Tools Required: Soft cloth, cleaning solution
Instructions:
1. Locate the front camera and radar sensors mounted typically at the front windshield and grill.
2. Use a soft cloth and cleaning solution to gently clean the sensors to remove any dirt or debris.
3. Ensure that there are no obstructions that could interfere with sensor operation.

3. Inspect and Adjust Alignment

Tools Required: Alignment machine (if available), wrench set
Instructions:
1. Check the front wheel alignment using an alignment machine; adjust if needed to manufacturer specifications.
2. Inspect tire pressure and tread depth, replacing tires if they are worn or improperly inflated.

4. Verify System Settings

Instructions:
1. Start the vehicle and navigate to the settings menu on the infotainment system.
2. Ensure that the lane keeping assist feature is activated.
3. If necessary, reset the LKA system to factory settings and then re-enable the feature.
