Open the Tesla app or use the vehicle's interface to access the battery health section.
Review the battery's current capacity and compare it with the original specifications.
If capacity is significantly reduced, consider contacting Tesla service for further evaluation.

4. Optimize Settings

Check the climate control settings; adjust to minimize battery drain.
Turn off any unnecessary features such as seat heaters or cabin pre-conditioning.
Review driving modes and adjust to "Chill" mode to enhance efficiency.

5. Inspect Tire Pressure and Condition

Use a tire pressure gauge to check the pressure of all four tires.
Inflate tires to the recommended PSI as specified in the owner's manual.
Visually inspect tires for wear or damage; replace if necessary.
