- Restart the vehicle after installation to ensure all settings are applied.

3. Tire Maintenance

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure; refer to the owner's manual for the recommended PSI.
- Inflate tires to the correct pressure if needed.
- Inspect tires for uneven wear or damage; rotate or replace as necessary.

4. Energy Consumption Optimization

Sub-steps:
- Access the energy consumption screen on the display to monitor usage.
- Adjust driving habits to maximize range, such as reducing speed and avoiding rapid acceleration.
- Turn off unnecessary accessories (e.g., heated seats, climate control) during drives.
