What is the emission standard for cars manufactured in 2009?

[ClaireDella]

2009 cars are either China III or China IV emission standard. Vehicles produced between July 2007 and September 2009 comply with China III standard, while those manufactured after September 2009 generally meet China IV standard. Here are methods to check your vehicle's emission standard: 1. Environmental label: Check the back of the car's environmental compliance label to easily identify the emission standard. 2. Vehicle certificate: The first page of the vehicle qualification certificate contains emission standard information, though not directly stated as "China X" but rather in coded characters. 3. Manufacturing date: You can roughly estimate the emission standard based on the vehicle's production year. 4. DMV: Bring your vehicle registration certificate (original or copy) to the local Department of Motor Vehicles for verification.
