Solution

1. Software Update

Connect the vehicle to Wi-Fi.
Navigate to the software update section in the infotainment system.
Download and install any available updates.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, air compressor
Check each tire's pressure using the gauge.
Inflate tires to the manufacturer's specified PSI (found on the door jamb).
Inspect tires for uneven wear or damage; replace if necessary.

3. Battery Health Assessment

Tools Required: Tesla service app or visit a Tesla service center
Access the battery health diagnostics through the vehicle settings.
If degradation is significant (typically over 10% loss), consider contacting Tesla for battery service or replacement.

4. Climate Control Management

Reduce reliance on climate control systems by using the seat heaters instead of cabin heating.
Set the climate control to a moderate temperature to minimize energy draw.
Utilize scheduled preconditioning when charging to maintain battery temperature without using excess energy.

5. Accessory Management

Tools Required: None
Turn off unnecessary accessories when not in use (e.g., heated seats, lights).
Limit the use of high-energy consumption features like gaming or video playback while parked.
