Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather tools including a diagnostic tool if necessary, and ensure the vehicle is fully charged.

2. Update Software

Navigate to the vehicle’s settings.
Select "Software" and check for any available updates.
If an update is available, follow the prompts to install it.

3. Inspect Battery and Performance Settings

Access the "Driving" settings from the touchscreen.
Confirm that the performance mode is set to "Standard" and not "Chill".
If the battery health is degraded (indicated by a significant drop in capacity), consider a battery assessment.

4. Brake System Check

Visually inspect the brake system for any signs of binding or malfunction.
If necessary, have the brake calipers and pads inspected by a qualified technician.

5. Test Drive

After the above checks and updates, conduct a test drive to assess acceleration response.
Pay attention to any abnormal sounds or resistance during acceleration.
