Components relevant to emission control
Introduction
This chapter contains information on the followingsubjects:
⇒ Emission control with AdBlue 
⇒ Refilling AdBlue 
⇒ Catalytic converter 
⇒ Particulate filter 
⇒ Troubleshooting 
⇒ Emission control with AdBlue® 
⇒ Catalytic converter 
⇒ Particulate filter 
Information on warning and indicator lamps that light up can be found in the section
Troubleshooting ⇒ Troubleshooting .

WARNING
Engine emissions contain carbon monoxide which can cause people to lose consciousness. It can also
cause death.




WARNING
The components of the exhaust system become very hot. This can cause fires.
inflammable material underneath the vehicle, e.g. dry grass.
-corrosion coatings to the exhaust pipes, catalytic
converters, particulate filter or the heat shields.
Emission control with AdBlue®
First read and observe the introductoryinformation and safety warnings⇒Introduction 
The SCR catalytic converter uses AdBlue® urea solution to convert nitrogen oxides into nitrogen and
water.

First read and observe the introductoryinformation and safety warnings⇒Introduction 
⇒ Petrol .
⇒ Refuelling .
⇒ Checking the engine oil level and refilling the engine oil .
⇒ Jump starting the vehicle .
If you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and
have the vehicle checked by a qualified workshop ⇒ Troubleshooting . Otherwise unburnt fuel can
enter the exhaust system and escape into the atmosphere. The catalytic converter can also be
damaged by overheating.

The emissions may have a sulphur-like smell even when the exhaust purification system is working
properly.
Particulate filter
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Function
⇒ Fuel standards .
⇒ Refuelling .
⇒ Engine oil standards .
⇒ Jump starting the vehicle .
Periodic regeneration
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.
To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making
only short journeys.
Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan
may run on while the vehicle is moving or when the engine has been switched off.

During the periodic regeneration process, the yellow indicator lamp does not light up.

If these symptoms occur directly after refuelling, switch off the engine immediately to avoid any
subsequent damage.

Vehicle toolkit
Introduction
This chapter contains information on the followingsubjects:
⇒ Stowage 
⇒ Vehicle toolkit contents 
Observe any country-specific legislation when securing your vehicle in the event of a breakdown.
Vehicle toolkit in the vehicle
In vehicles that are factory-fitted with a spare wheel, emergency spare wheel or winter wheels,
additional vehicle tools may be located in the luggage compartment.

WARNING
In the event of a sudden driving or braking manoeuvre or accident, a loose vehicle toolkit,
breakdown set and spare wheel or temporary spare wheel could be flung though the vehicle and
cause severe injuries.
always secured in the luggage compartment.

WARNING
Unsuitable or damaged tools in the vehicle toolkit can lead to accidents and injuries.

Stowage

The content of the vehicle toolkit varies according to the vehicle equipment level ⇒ Fig. 162 . The
following describes the maximum scope.
Key to ⇒ Fig. 162 :
Screwdriver with hexagon socket in the handle for unscrewing or tightening slackened wheel
bolts. The screwdriver blade is reversible. The screwdriver may be stowed under the box spanner.
Adapter for the anti-theft wheel bolt. Volkswagen recommends that you carry the wheel bolt
adapter in the vehicle toolkit at all times. The code number of the anti-theft wheel bolt is engraved
on the front of the adapter. You will need this number to replace the adapter if lost. Make a note of
the code number for the anti-theft wheel bolt and keep it in a safe place – but not inside the vehicle.
Removable towing eye.
Wire hook for pulling off the centre wheel trims, wheel covers and the wheel bolt caps.
Vehicle jack. Before you repack the jack, you must fully wind in the claw.

Vehicle jack: maintenance
There are no maintenance cycles for the vehicle jack. Grease it with universal lubricant when
necessary.

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.
⇒ In the
engine compartment . The engine compartment of any motor vehicle is a dangerous area. Serious
injuries can be sustained here.


change a bulb unless you are familiar with the procedure. If you are uncertain of what to
do, the work should be carried out by a qualified workshop.
heat will cause fingerprints to evaporate on the bulb, which in turn will cause the reflector to go
blind.
-edged parts in the headlight housing in the engine compartment and on the tail
light cluster housing. Protect your hands when changing bulbs.

NOTICE
Damage to the electrical system can be caused by water entering the system if the rubber cover or
plastic covers on the headlight housing are not properly mounted after a bulb has been changed.
Checklist Information on changing bulbs

First read and observe the introductoryinformation and safety warnings⇒Introduction 
Checklist
Always carry out the following actions for changing a bulb in the given order ⇒ :

Park the vehicle on a firm and level surface at a safe distance from the flow of traffic.

Switch on the electronic parking brake Electronic parking brake.

Turn the light switch to position 0 Switching lights on and off.

Move the turn signal and main beam lever to neutral position Switching turn signals on and off.

Automatic gearbox: move the selector lever to position P DSG® dual clutch gearbox.

Stop the engine and remove the vehicle key from the ignition Starting the engine.

Manual gearbox: select a gear Manual gearbox: selecting a gear.

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.

Open the bonnet ⇒ In the engine compartment .

Pull off the rubber cover on the rear side of the headlight. Depending on the version, a hard plastic
cover may be fitted here. Turn the cover anti-clockwise and remove it.

Dipped beam ① Turn the bulb holder anticlockwise as far as it will go and carefully pull it out to the
rear along with the bulb.
Main beam ② Press on the bulb from below, as shown by the arrow, until it engages. Lift the bulb
back and out.

Replace the defective bulb with a new bulb of the same type.

Dipped beam ① Insert the bulb holder into the headlight and turn it clockwise as far as it will go.
Main beam ② Insert the bulb into the opening in the headlight with the connector at the top and
push down. The lug of the bulb must be located in the headlight recess (small arrow).
