Solution

1. Preparation

Ensure the vehicle is parked in a safe area.
Disconnect any charging cables.
Gather necessary tools including a tire pressure gauge and a laptop with Tesla diagnostic software.

2. Battery Health Assessment

Access the vehicle's settings via the Tesla app or onboard display.
Navigate to "Battery" settings and check for the current capacity and health status.
If the battery health is below 80%, consider contacting Tesla for a battery replacement.

3. Tire Inspection and Maintenance

Use a tire pressure gauge to check the pressure in all tires.
Inflate tires to the manufacturer’s recommended psi (found on the driver’s side door jamb).
Inspect tires for uneven wear or damage; replace if necessary.

4. Software Update

Connect the vehicle to Wi-Fi and check for available software updates.
If an update is available, follow on-screen instructions to install the update, which may improve battery management.

5. Driving Behavior Adjustment

Review energy consumption statistics and adjust driving habits to reduce aggressive acceleration and high-speed driving, both of which can impact range.
Monitor climate control usage, as heating and cooling can significantly affect battery life.
