• Avoid harsh braking: Sudden braking can sometimes trigger the inertia switch. Try to brake smoothly and avoid abrupt stops.
• Be cautious on rough roads: Driving on bumpy roads or roads with potholes can also trigger the inertia switch. Drive slowly and carefully in these conditions.
• Regularly inspect the switch: Check the inertia switch periodically to make sure it’s clean and free of debris.
