Solution

1. Preparation

Gather necessary tools: OBD-II scanner (if needed), vehicle manual.
Ensure the vehicle is in a well-ventilated area and that the ignition is off.

2. Reset the Infotainment System

Turn the ignition to the 'ON' position without starting the engine.
Wait for the infotainment system to boot up.
Press and hold the 'Home' button and the 'Volume' knob simultaneously for about 10 seconds until the system reboots.

3. Reset the Time and Date

Start the engine.
Access the settings menu on the infotainment display.
Navigate to 'Settings' > 'Time and Date'.
Adjust the settings to reflect the correct time and date.

4. Clear Error Codes (if applicable)

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition (do not start the engine).
Follow the scanner prompts to read and clear any DTCs (Diagnostic Trouble Codes).
Disconnect the scanner once completed.

5. Recalibrate the Electronic Systems

Drive the vehicle at various speeds and conditions to allow the engine control unit (ECU) to relearn parameters.
If equipped, recalibrate the electronic throttle control by performing a full throttle and then releasing it.
