2. Connect the vehicle to Wi-Fi and check for available updates.
3. If updates are available, initiate the update process and allow the vehicle to complete it.

3. Driving Habits Adjustment

Sub-steps:
1. Review driving statistics on the touchscreen to identify aggressive acceleration or high-speed driving.
2. Encourage smoother acceleration and deceleration.
3. Limit heavy use of regenerative braking settings to find a balance that optimizes energy consumption.

4. Climate Control Management

Sub-steps:
1. Check the climate control settings; consider using scheduled pre-conditioning while plugged in.
2. Adjust settings to reduce high energy-consuming features such as heated seats and steering wheel unless necessary.
3. Utilize the "ECO" mode for climate control to improve efficiency.
