In the interests of maintaining clean air
Environmental pollution has become a big problem that cannot but worry each of us. We are urgently requested to pay attention to maintaining clean air by monitoring the level of pollution of exhaust gases emitted by the car.
You can make a significant contribution to maintaining clean air around you. To do this, you need to:
- Use only unleaded petrol.
- Do not allow your vehicle to idle unnecessarily.
- Strictly follow the recommended maintenance schedule for your vehicle.
- Do not remove or modify the exhaust emission control system.
- Take all necessary precautions listed below to avoid damaging your vehicle's emission control system.
Volkswagen guarantees the correct operation of the exhaust gas control system of the vehicle, provided that all operating requirements are met. The Volkswagen Jetta is equipped with an exhaust gas control system, which consists of the following components:
Catalytic converter of exhaust gases
A catalytic converter is an effective cleaning device installed inside the exhaust system of a car. The catalytic converter burns off unwanted toxic components of the exhaust gas before it is released into the atmosphere.
Using only unleaded fuel is extremely important for the catalytic converter to extend its service life and ensure normal engine operation:
The catalytic converter will be continually exposed to negative influences when:
- Exceeding the maximum permissible engine oil level.
- Starting your car with a tow.
- Engine misfire.
- Switching off the ignition when the vehicle is moving or under other undesirable operating conditions.
Under these conditions, stop using the vehicle, otherwise fuel may enter the catalytic converter, which in turn will lead to its overheating and the need to replace the converter.
Oxygen sensor (OS)
The oxygen sensor, installed in the exhaust manifold, continuously measures the oxygen content in the exhaust gases and transmits this information to the electronic control unit.

Carbon filter
The car is equipped with a carbon filter that prevents fuel vapors from entering the atmosphere.
Fuel vapors enter the carbon canister where they are trapped when the engine is off. When the engine is running, a valve allows air to enter the carbon canister and the fuel vapors enter the engine where they are burned. The system is maintenance-free.
To ensure efficient operation of the exhaust gas control system:
- Perform regular maintenance on your vehicle according to the recommended schedule, otherwise it may adversely affect the performance of the emission control system and may cause damage to it.
- Do not modify or remove any emission control system components unless approved by the manufacturer.
- Do not modify or cement any devices such as heat shields, switches, ignition wires, valves, which are designed to protect the emission control system.
Note: Do not leave your car running in idle mode after starting the engine. Pay attention to the warning lights that light up, indicating the presence of one or another malfunction in the engine. Long-term operation of the engine in idle mode leads to overheating of the car or other damage.
Caution: Parking Do not park or operate the vehicle where the hot exhaust system may come into contact with dry grass, spilled fuel or other materials that may ignite and cause a fire.
Primer. Do not apply additional primer or anti-corrosion coatings on or near the exhaust manifold, downpipes, catalytic converter, or heat shields. When the vehicle is driven, the material used in these types of coatings may overheat and cause a fire.
