• Note symptoms: unusual noises, loss of power, rough idle, exhaust smell — share these details with service staff to speed diagnosis.
• Avoid repeated hard driving if the light flashes; contact our service team to schedule a quick scan and protect the catalytic converter and engine.
• For warranty protection and accuracy, let our certified technicians perform any resets or repairs rather than clearing codes at home.
