and engine failure.
Petrol
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Fill vehicles with a petrol engine only with unleaded petrol or petrol with a maximum ethanol
content of 10 % (E10) ⇒ .
Fuel grades differ according to the octane number. The vehicle may be filled with petrol that has a
higher octane number than the engine requires. However, this does not provide any advantage in
terms of fuel consumption or engine output.
The fuel quality affects the running properties, performance and service life of the engine. Refuel
with fuel that already contains suitable service additives ⇒ .
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards .

drive at medium engine speeds and avoid high engine loading. Avoid high engine speeds and heavy
engine loads. Refuel with petrol with the correct octane number as soon as possible.
Diesel
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Fill vehicles with a diesel engine only with diesel or diesel with a maximum RME fuel content of 7 %
⇒ .
If you use diesel with a high sulphur content, the service intervals are shorter. Information on
countries where the diesel has a high sulphur content is available from your Volkswagen dealership
or a qualified workshop.

Winter-grade diesel fuel and filter preheater system
Winter-grade diesel fuel, which can be used at temperatures below -20°C (-4°F), is available during
the cold months. In countries with different climates, diesel with a different temperature behaviour
is offered. Information is available from your Volkswagen dealership, qualified workshops and filling
stations in the respective country.
Diesel vehicles are equipped with a filter preheater system. When using winter-grade diesel fuel, the
fuel system is safe for operation at temperatures down to around -24°C (-11°F). In order to ensure
that the vehicle can also be started at low outside temperatures, Volkswagen recommends parking
the vehicle in a location that is protected from the whether, e.g. in a garage ⇒ Troubleshooting .
Misfuelling prevention device
The tank filler neck in diesel vehicles may be fitted with a misfuelling prevention device. This is
intended to help ensure that the vehicle is refuelled only using diesel filler nozzles.
If the nozzle cannot be inserted correctly into the tank filler neck, first check whether you are using a
diesel filler nozzle. When you have made sure that you are using the correct filler nozzle, move the
diesel filler nozzle to and fro slightly with light pressure. This can open the misfuelling prevention
device and make it possible to refuel the vehicle. If the misfuelling prevention device still remains
closed, go to a qualified workshop and have the system checked.
If it is necessary to refuel the vehicle using a fuel canister in the event of an emergency, the
misfuelling prevention device will not open. In order to nevertheless fill the tank with fuel, pour the
diesel into the tank extremely slowly in very small quantities.

Changing bulbs
Introduction
This chapter contains information on the followingsubjects:
⇒ Checklist  
⇒ Changing bulbs in the front headlights (halogen bulbs) 
⇒ Changing the bulbs in the headlights (lights with LED technology) 
⇒ Changing the front turn signal bulbs 
⇒ Changing bulbs in the front bumper 
⇒ Changing bulbs in the tail light clusters (LED lights) 
⇒ Changing bulbs in the number plate light (LED lights) 
⇒ Troubleshooting 
Changing the vehicle bulbs requires a certain amount of technical skill. Volkswagen therefore
recommends having bulbs replaced by a qualified workshop if you are uncertain. The work must be
performed by an expert if other vehicle parts around the affected bulbs need to be removed.
Volkswagen recommends having bulbs replaced by a Volkswagen dealership.
You should keep a box with spare light bulbs for the lights that ensure the vehicle is roadworthy in
the vehicle at all times. Spare bulbs are available from Volkswagen dealerships. In some countries it
is a legal requirement to have these spare bulbs in the vehicle.
It may be illegal to drive with defective lights of the exterior lighting.
Information on indicator and warning lamps can be found in the troubleshooting section at the end
of the chapter ⇒ Troubleshooting .
LED lights on the vehicle
The exterior lighting may feature LEDs: Owners cannot replace the LEDs themselves. If some LEDs
fail, this may be an indication that more elements are on the point of failure. In this case, have the
lights checked and replaced if necessary at a qualified workshop.

Additional bulb specifications
Some bulbs in headlights or in tail light clusters might have factory specifications that are different to
standard bulbs. The designation is inscribed on the bulb, either on the glass part or on the base.

WARNING
Accidents can occur if roads are not sufficiently illuminated and other road users have difficulty
seeing the vehicle, or cannot see it at all.

WARNING
Changing bulbs incorrectly can cause accidents and serious injuries.

Allow the orientation lighting to go out Coming Home and Leaving Home function (orientation
lighting).

Leave the defective bulbs to cool down.

Check to see if a fuse has visibly blown Changing fuses.

Follow the instructions to change the affected bulb . Always replace bulbs with identical bulbs of the
same type. The designation is inscribed on the bulb, either on the glass part or on the base.

Do not touch the glass part of the bulb with unprotected fingers. When switched on, the heat of the
bulb would cause the remaining fingerprint to evaporate and be deposited on the reflector. This will
impair the light output of the headlight.

After changing a bulb, check to ensure that the bulb is working properly. If the bulb is not working
properly, the bulb may not have been inserted properly, may have failed again, or the connector
may have been fitted incorrectly.

Any time you change a bulb at the front of the vehicle, the headlight settings should be checked by a
qualified workshop.

WARNING
Ignoring any of the items on this important safety checklist can lead to accidents and severe injuries.


NOTICE
Always take care when removing or fitting lights to prevent damage to the paintwork or to other
vehicle parts.
