Fuel and emissions control system

Safety precautions for handling fuel

WARNING

Handling fuel incorrectly can cause explosions, ﬁres, severe burns, and other injuries.

Before refueling, switch off the engine, the ignition and your cell phone, as well as other radio equipment.

To reduce the risk of discharging static electricity, do not enter the vehicle while refueling.

Make sure that the fuel tank cap is sealed correctly and no fuel is leaking out.

Note the applicable safety precautions and local regulations for handling fuel.

WARNING

Refueling incorrectly can cause ﬁres, serious injuries, and vehicle damage.

Only use fuel that is approved for your vehicle.

Do not use any fuels containing metal and only use service additives approved by Volkswagen in the respective proportion.

Immediately remove any fuel that has spilled on vehicle components.

CAUTION

Fuel may leak out of reserve canisters. This can cause ﬁres and injuries.

Do transport any reserve canisters in the vehicle.

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

The fuel filler flap does not have an emergency release. If necessary, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for

assistance.

Fuel types and refueling

Introduction

The fuel ﬁller ﬂap is located on the right rear side of the vehicle.

Designation of fuels and fuel standards

Refer to ⇒

and

Safety precautions for handling fuel.

Fig. 168 On the inside of the fuel filler flap: fuel label (general example)

Fuel label

The type of fuel to use depends on the vehicle engine. When your vehicle leaves the factory there is a fuel information sticker inside the tank ﬂap with notes about

the minimum required fuel type for your vehicle ﬁg. 168.

The name speciﬁes which fuels are suitable for the vehicle. This is a minimum requirement

⇒

279

Fuel standards

The fuel used must meet one of the following standards. The vehicle must not be refueled with other fuels

⇒

If fuel with the speciﬁed standards is not available, contact suitably qualiﬁed professionals for information about which fuels are suitable for the vehicle. Volkswagen

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

Gasoline

Gasoline and methanol mixture

AKI 87 or higher.

Maximum 3% methanol.

Gasoline and ethanol mixture

AKI 87 or higher.

Maximum 15% ethanol.

Gasoline and MTBE mixture

AKI 87 or higher.

Maximum 15% MTBE.

NOTICE

Refueling with non-standard and non-approved fuels can cause reduced performance and considerable damage to the engine and the fuel system.

Before refueling, check if the fuel speciﬁcation at the fuel pump meets the vehicle speciﬁcations.

Only refuel using fuels that conform to the speciﬁed standards and name to reduce the risk of damage to the fuel system and engine malfunctions.

Gasoline

Refer to ⇒

and

Safety precautions for handling fuel.

Gasoline types

The gasoline types differ in terms of their AKI (Anti-Knock Index) speciﬁcation, which is given from the formula (RON +MON)/2, or the Research Octane Number

(RON) speciﬁcation. The vehicle may also be fueled with gasoline that has a higher AKI or RON than what is required by the engine. However, this will not improve

fuel consumption or engine power.

Arteon, Atlas 2.0 and Jetta GLI: Volkswagen recommends using premium-grade fuel with AKI 91 or ROZ 95 in order to achieve the speciﬁed power and torque.

The fuel information label may have multiple gasoline types, for example AKI 93 min. 91. The highlighted gasoline type, AKI 93 in this example, is the preferred

gasoline type for which the vehicle is designed and optimized. The listed alternative gasoline type, AKI 91 in this example, should only be used if the preferred type,

AKI 93 in this example, is not available.

If your vehicle has a gasoline engine, fuel it only with gasoline that does not contain any metal (no lead, manganese or iron)

⇒

The most frequently purchased gasoline types in the USA and Canada have the following octane values, which are normally listed on the fuel pump:

Regular (normal gasoline): AKI 87 to 90 or ROZ 91.

Premium (super gasoline): AKI 91 to 93 or ROZ 95.

Volkswagen recommends using “TOP TIER Detergent Gasoline”, which is available in some regions, for example North America, Central America and South

America. For more information on “TOP TIER Detergent Gasoline”, visit the ofﬁcial website at:

NOTICE

Using gasoline that does not meet the minimum octane number requirements may reduce engine performance, while the use of poor-quality gasoline or

gasoline with an AKI of below 87 or a ROZ of under 91 could also result in engine damage.

Refueling

and

Safety precautions for handling fuel.

Refueling procedure

1. To unlock the fuel ﬁller ﬂap, unlock the vehicle with the

button on the remote control vehicle key ⇒ Vehicle key functions.

Or: to unlock the fuel ﬁller ﬂap, unlock the vehicle with the

button in the driver door ⇒ Central locking button.

On vehicles with Keyless Access, the fuel ﬁller ﬂap is automatically unlocked when the vehicle is unlocked.

2. Open the fuel ﬁller ﬂap.

3. Remove the fuel tank cap and insert it into the opening at the fuel ﬁller ﬂap provided for this ﬁg. 169.

4. Hold the fuel pump nozzle handle down to ensure optimum refueling.

The fuel tank is full once the fuel pump nozzle turns off for the ﬁrst time

5. Screw the fuel tank cap onto the fuel ﬁller neck.

6. Close the fuel ﬁller ﬂap.

⇒

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 ⇒ Troubleshooting.

WARNING

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

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

NOTICE

Every six months, if possible, run the fuel tank empty until the indicator light comes on and refuel it. This is required to maintain the system functions and fuel

quality necessary for operation.

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

Exhaust system

Introduction

The exhaust-relevant components reduce exhaust emissions:

Catalytic converter ⇒ Catalytic converter.

Particulate ﬁlter (depending on the vehicle equipment) ⇒ Particulate ﬁlter.

WARNING

Engine exhaust contains carbon monoxide, which can cause loss of consciousness and death.

Do not allow the engine to run in conﬁned spaces.

Never start the engine in conﬁned spaces.

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