Solution

1. Verify Software Version

Navigate to the vehicle’s settings on the touchscreen.
Go to "Software" and confirm the current version matches the latest release.
If there’s a newer version, initiate the update process.

2. Adjust Performance Settings

Access the “Driving” settings on the touchscreen.
Ensure that the "Acceleration" mode is set to "Sport" for maximum performance.
Check the “Chill Mode” setting; if enabled, disable it for improved throttle response.

3. Battery Management

Inspect the battery charge level; it should be above 20% for optimal performance.
If the battery is low, charge the vehicle to at least 80% before testing acceleration again.

4. Reset Vehicle Systems

Perform a soft reset of the vehicle by holding down both scroll wheels on the steering wheel until the screen reboots.
After the reset, check the performance again.

5. Restore Factory Settings

Navigate to “Settings” on the touchscreen.
Select “Service” and then “Restore Factory Settings.”
Follow on-screen prompts to complete the restoration, then re-evaluate the vehicle's performance.
