Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turned off.
Gather necessary tools: OBD-II scanner, laptop or mobile device for software updates, and a torque wrench if needed.

2. Update Software

Connect the vehicle to a stable Wi-Fi network.
Access the software update section from the vehicle's touchscreen.
Download and install any available updates, following on-screen prompts.

3. Inspect Battery and Power Settings

Check the state of charge through the vehicle’s display.
Adjust driving modes in the settings menu if the vehicle is in a mode that limits acceleration (switch to Standard or Sport mode).
If the battery is low, charge the vehicle to at least 50% to ensure optimal performance.

4. Clear Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostics port.
Retrieve and document any fault codes.
Clear any non-critical fault codes that may affect performance.

5. Test Drive

After performing the above steps, conduct a test drive to evaluate acceleration.
Monitor for any changes in the response during acceleration.
