Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is turned off.

Remove the negative and positive terminals from the battery.
Clean the battery terminals and cable connectors using a wire brush to remove corrosion.
Reconnect the battery terminals, starting with the positive terminal, followed by the negative.

Open the hood and inspect all fluid reservoirs (brake fluid, coolant, windshield washer fluid).
Top off any low fluids with the appropriate type as specified in the owner's manual.

5. Inspect Parking Brake

Verify that the parking brake is fully released.
If the parking brake is malfunctioning, inspect the cable and actuator for any issues.
