Do not continue filling after disconnection. The expansion area in the fuel tank may fill with fuel, e.g. due to heating.

This may mean that the fuel overflows or the automatic ventilation process cannot work .

WARNING

Fuel may spray out and overflow if the fuel tank is overfilled. This can cause explosions, fires, and serious or fatal

injuries.

● Do not continue filling after the pump nozzle switches off for the first time.

NOTICE

If the tank content is not consumed up to the reserve quantity at regular intervals, it may not be possible to

maintain the fuel quality and system function required for driving, under certain circumstances.

● Refuel at least every six months, but only when the warning light turns on.

Fuels can contaminate the environment. Collect any leaking operating fluids and dispose of them according

to legal regulations.

Introduction

The exhaust-relevant components reduce exhaust emissions:

—AdBlue^®(→ AdBlue).

—Catalytic converter (→ Catalytic converter).

—Particulate filter (depending on the vehicle equipment)(→ Particulate filter).

WARNING

If the engine runs in enclosed spaces, poisonous gases may enter the vehicle interior. This can cause serious injuries

and death due to asphyxiation.

● Never start the engine in confined spaces.

● Do not allow the engine to run in confined spaces.

● Do not leave your vehicle unattended while the engine is running.

WARNING

The parts of the exhaust system become very hot and can ignite flammable materials, for example shrubs, leaves,

dry grass or spilled fuel. This can lead to a fire and cause accidents and serious or fatal injuries.

● Never park the vehicle in such a way so that the exhaust system components come into contact with flammable

materials under the vehicle.

● Never use additional undercoating or corrosion protection for exhaust pipes, catalytic converters, heat shields, or

particulate filters.

AdBlue®

®

The SCR catalytic converter uses AdBlue^®to convert nitrogen oxides into nitrogen and water. AdBlue is a

registered brand and also known as AUS32 or DEF (Diesel Exhaust Fluid).

Legal notes

No technical changes may be made to the emission control system that influence emission control by AdBlu^®e.

Only the use of AdBlue^®that corresponds to the ISO-22241-1 standard is approved by Volkswagen and corresponds

to the certificate of conformity issued for this vehicle type.

®

It can be a punishable offense to operate the vehicle without AdBlue that corresponds to the ISO-22241-1 standard.

If the emission control system is not operated as intended, the exhaust emissions can deteriorate.

®

Information on AdBlue

AdBlue^®consumption is dependent on driving style, operating temperature, and the ambient temperature. The

remaining range and refilling quantity can be checked in the instrument cluster display .

Since AdBlue^®freezes below -11°C(+12 °F), you may encounter restrictions when filling up at very low temperatures.

During vehicle operation, the system is heated to ensure emission control also at very low temperatures.

®

It is possible that AdBlue cannot be thawed in long, cool periods at temperatures below -11 °C(+12 °F) and in very

poor conditions, and the emission control system is not available (→ AdBlue).

®

You should top up AdBlue regardless of service events. This can be necessary more often and between service

intervals.

The AdBlue^®tank must not be empty .

Warning and prompt system at low fill level

®

Always top up AdBlue when a refilling prompt appears in the instrument cluster display.

If the white indicator light turns on, AdBlue^®is still in the standard operating range. It is possible but not necessary

to top up AdBlue^®.

®

From a remaining range of 2000 km(1200 miles), you will be prompted to refill AdBlue in the instrument cluster

display. The current remaining range is also displayed together with this prompt (→ AdBlue).

Failure to observe this prompt will cause the yellow indicator light to come on when theremaining range drops

below 1000 km (600 miles). A message stating that it will no longer be possible to restart the engine in XXX km

(XXX miles) appears in the instrument cluster display.

If the yellow indicator light is still ignored and the displayedremaining range is 0 km(0 miles), it will no longer be

possible to restart the engine. The red warning light lights up.

Warning and prompt system in the event of errors

®

If the emission control system is malfunctioning or you have filled up non-standard-compliant AdBlue as per ISO-

22241-1, the white or yellow indicator lights

Catalytic converter

To ensure that the exhaust system and the engine catalytic converter can work correctly for a long time, observe the

following:

—Only refuel with fuel permitted for the vehicle.

—Never drive until the fuel tank is completely empty (→ Fuel types and refueling).

—Never add too much engine oil (→ Engine oil).

—Do not tow-start the vehicle; use jump-start assistance instead (→ Jump-starting).

If there are engine misfires, loss of power, or poor engine operation while driving, reduce the speed immediately and

have the vehicle checked by suitably qualified professionals . Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility. Otherwise, uncombusted fuel could be present in the

exhaust system and then enter the atmosphere. The catalytic converter may also be damaged from overheating.

The exhaust may smell like sulfur when the emissions control system is running

correctly.

478

Particulate filter

Function

The particulate filter depends on the vehicle equipment and filters out soot from the exhaust gas.

Regeneration

With normal vehicle usage, the filter cleans itself. If the filter is unable to clean itself, e.g. if you only make short trips

for an extended period of time, the filter can become blocked with soot. The particulate filter needs to be cleaned

(regenerated).

Noises, light odors, and increased engine speeds may occur during the regeneration. The radiator fan may continue

to run while driving and after turning off the engine.

To assist in particulate filter regeneration, Volkswagen recommends avoiding driving short distances too frequently.

The soot in the particulate filter is burned periodically at high temperatures. The yellow indicator light

does not turn on during a periodic regeneration.

479

Troubleshooting

If the engine does not run smoothly and malfunctions

If the engine does not run smoothly or malfunctions while driving, it can indicate poor fuel quality.

1. Reduce your speed immediately.

2. Drive with a moderate RPM and low engine load to the nearest suitably qualified professional. Volkswagen

recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

3. If these symptoms occur directly after refueling, stop the engine immediately to prevent subsequent damage.

4.

Do not continue driving! Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility

for assistance.
