Solution

1. Preparation

Gather tools: OBD-II scanner (if applicable), tire pressure gauge, and access to Tesla app.
Ensure the vehicle is parked on a flat surface and is in "Park" mode.

2. Check Tire Pressure

Use the tire pressure gauge to measure the pressure in each tire.
Inflate or deflate the tires to the recommended specifications found on the driver’s side door jamb.

3. Analyze Energy Consumption

Access the energy consumption statistics through the touchscreen.
Identify any patterns of high energy use by reviewing past trips and adjust driving habits accordingly.

4. Update Software

Connect the vehicle to Wi-Fi and check for any available software updates in the settings menu.
Follow on-screen prompts to install any available updates to enhance battery efficiency.

5. Climate Control Adjustment

Limit the use of climate control features while driving. Consider pre-conditioning the vehicle while it is still plugged in.
Adjust settings for less power consumption, such as reducing seat heater levels.
