Solution

1. Tire Inspection and Adjustment

Sub-steps:
- Check tire pressure using a tire pressure gauge.
- Inflate tires to the recommended pressure as per the owner's manual.
- Inspect tire tread for uneven wear; replace tires if necessary.

2. Software Update

Sub-steps:
- Access the vehicle's settings and navigate to the software update section.
- Check for available updates and install them if found.
- Restart the vehicle after the update to ensure all systems are refreshed.

3. HVAC System Optimization

Sub-steps:
- Adjust climate control settings to Eco mode to reduce energy consumption.
- Limit the use of heated seats and steering wheel if not necessary.
- Precondition the vehicle while still plugged in, so the HVAC does not draw from the battery while driving.

4. Reduce Aerodynamic Drag

Sub-steps:
- Remove any unnecessary cargo or roof racks from the vehicle.
- Ensure windows are closed while driving to minimize wind resistance.

5. Battery Health Check

Sub-steps:
- Access the battery health status through the vehicle’s settings.
- If the battery shows signs of degradation, consult Tesla service for potential replacement.
