Solution

1. Preparation

Tools Needed: Tesla app, tire pressure gauge, software update tools.
Ensure the vehicle is parked on a level surface and is turned off.

2. Battery Health Check

Access the Tesla app or vehicle settings.
Navigate to the battery section and review the current health status.
If health is significantly below 80%, consider battery servicing or replacement.

3. Software Update

Go to the settings menu on the touchscreen.
Check for any available software updates and install them.
Restart the vehicle if prompted, to ensure all updates take effect.

4. Tire Maintenance

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the recommended pressure as indicated on the door jamb label.
Inspect tires for uneven wear; replace or rotate if necessary.

5. Cooling System Inspection

Open the front trunk and locate the battery cooling system components.
Check for any visible blockages or debris on the cooling fins.
If any issues are found, clean the area and ensure proper airflow.

6. Charging Efficiency Test

Fully charge the vehicle and note the time taken to reach full capacity.
If the charging time is significantly longer than usual, inspect the charging station and cables for faults.
