Solution

1. Preparation

Gather necessary tools and equipment, including a multimeter, OBD-II scanner (if applicable), and a tire pressure gauge.
Ensure the vehicle is parked in a safe location with sufficient space to work.

2. Battery Health Assessment

Use the Tesla app to check the current battery capacity and health status.
If the battery capacity is significantly lower than expected, consider scheduling a service appointment through the Tesla app for a professional evaluation.

3. Tire Inspection and Maintenance

Check tire pressure using a tire pressure gauge; ensure they are inflated to the manufacturer's recommended PSI.
Inspect tires for uneven wear, damage, or low tread depth; replace tires if necessary.

4. Energy Consumption Analysis

Access the energy consumption settings in the vehicle to review which features or driving habits may be consuming excess energy.
Consider adjusting settings for climate control, seat heaters, and other high-energy features.

5. Software Update

Check for and install any available software updates through the vehicle's settings menu to ensure optimal performance of the battery management system.
