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 ⇒:
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 the bulb incorrectly can cause accidents and serious injuries.
•When working in the engine compartment, always read and observe the safety
warnings ⇒ In the engine compartment. The engine compartment of any motor vehicle
is a dangerous area. Serious injuries can be sustained here.
•H7/H15 bulbs are pressurised and could explode when they are being changed.
•Only change the defective bulb once it has had time to cool down completely.
•Never 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.
•Do not touch the glass part of the bulb with unprotected fingers. When the light is
switched on, heat will cause fingerprints to evaporate on the bulb, which in turn will
cause the reflector to dim.
•There are sharp-edged parts in the headlight housing in the engine compartment and
on the tail light cluster housing. Protect your hands when changing bulbs.
WARNING
Damage to the electrical system can be caused by water entering the system if the rubber
covers or plastic caps on the headlight housing are not properly mounted after a bulb has
been changed.
NOTICE

Check to see if a fuse has blown Changing fuses.
Follow the instructions to change the affected bulb . Always use identical bulbs with the
same designation. 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. The heat of the bulb would
cause the fingerprint to evaporate and condense on the reflector. This will impair the
brightness of the headlight.
After changing the 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 or may have failed again,
or the connector may have been inserted incorrectly.
Any time you change a bulb in the front of the vehicle, the headlight settings should be
checked by a qualified workshop.

Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Lighting
Vehicle lighting not working partially or completely. A separate display appears in the
instrument cluster if there is a cornering light fault.A trailer turn signal or all trailer lights have
stopped working.
Check the exterior lighting and change the appropriate bulb as required ⇒ Changing bulbs. If all
bulbs are OK or there is a fault in the dynamic cornering light, go to a qualified workshop.
Monitoring the lights on a connected trailer
For vehicles with a factory-fitted towing bracket, the vehicle will also monitor certain bulbs on a
trailer which has been connected properly via the trailer socket.
If a trailer turn signal or all the trailer lights fail, the indicator lamp in the instrument cluster will
go out.
Changing fuses
Introduction
This chapter contains information on the followingsubjects:
⇒ Fuses in the dash panel
⇒ Fuses in the engine compartment
⇒ Fuse table for fuses in the dash panel
⇒ Fuse tables for fuses in the engine compartment
⇒ Changing a blown fuse
At the time of print we are unable to provide an complete overview of the locations of the fuses for
the electrical consumers. This is because the vehicle is under constant development, because
fuses are assigned differently depending on the vehicle equipment level and because several
consumers may use a single fuse. You can get more information about the fuse layout from a
Volkswagen dealership.
Several electrical consumers could share a single fuse. Conversely, a single consumer could have
more than one fuse.
Therefore fuses should only be replaced when the cause of the fault has been rectified. If a new
fuse blows shortly after insertion, have the electrical system checked by a qualified workshop as
soon as possible.

Tow-starting or towing
Introduction
This chapter contains information on the followingsubjects:
⇒ Notes on tow-starting and towing
⇒ Fitting the rear towing eye
⇒ Fitting the front towing eye
⇒ Fitting the front towing eye (R-Lineyf
⇒ Driving notes when towing
Tow-starting is where a vehicle is started from it being set in motion by a vehicle that is hitched up
to it.
Towing is where a vehicle that cannot be driven is pulled away with the aid of another vehicle.
Observe any legal requirements when towing or tow-starting.
For technical reasons, vehicles with a discharged 12-volt battery must not be towed.⇒ Jump 
starting
Vehicles with Keyless Access must only be towed with the ignition switched on.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the 12-
volt vehicle battery. Depending on the charge level of the 12-volt vehicle battery, the drop in voltage
can be large enough after just a few minutes that electrical consumers in the vehicle will no longer
function, e.g. the hazard warning lights.
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode,
which can lead to serious injuries. Please observe the following in order to reduce the risk
of the 12-volt vehicle battery exploding:
•All work on the 12-volt vehicle battery and the electrical system can cause serious
chemical burns, fire or electric shocks. Always read the warnings and safety
information before carrying out any kind of work on the 12-volt vehicle battery ⇒ 12-
volt vehicle battery.
•Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle
battery.
•Attach the connector cables in the correct order – the positive cable first, followed by
the negative.
•Never connect the negative cable to parts of the fuel system or to the brake lines.
•The non-insulated parts of the battery clamps must not be allowed to touch. The jump
lead attached to the positive terminal on the 12-volt vehicle battery must not touch
electrically conductive parts of the vehicle.
•m/k/a995MK Vehicles with battery in the engine compartment: check the battery
window on the 12-volt vehicle battery. Use a torch for this if necessary. If the display is
light yellow or colourless, do not jump start the vehicle. Seek expert assistance.
•Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The explosive
gas emitted from the 12-volt vehicle battery could be ignited by sparks.
•Do not carry out jump starting if the 12-volt vehicle battery is damaged or if it is or has
ever been frozen.
WARNING
Once the vehicle has been successfully jump-started, go to a qualified workshop and have
the 12-volt vehicle battery checked.
NOTICE

Fig. 222 Front bumper, right-hand side: screwing in the towing eye.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The towing eye is screwed into a threaded hole behind a cover on the right of the front bumper
⇒ Fig. 221.
The towing eye must always be kept in the vehicle.
Observe the notes on towing ⇒ Notes on tow-starting and towing.
Fitting the towing eye at front
•Remove the towing eye from the vehicle tool kit in the luggage compartment.
•Push the area of the cover pointing towards the vehicle ⇒ Fig. 221 in the direction of the arrow
to release the cover fastener.
•Remove the cover and leave it hanging from the vehicle.
•Turn the towing eye anti-clockwise into the threaded hole and tighten as far as possible
⇒ Fig. 222⇒. Use a suitable object to screw the towing eye fully and securely into the
mounting.
•After you have finished towing, remove the towing eye by unscrewing it with a suitable object
clockwise.
•Insert the lug on the cover on the opening pointing towards the vehicle side in the bumper and
push on the opposite area of the cover until the lug engages in the bumper.
•If necessary clean the towing eye and place them back in the vehicle tool kit in the luggage
compartment.
Driving notes when towing
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Towing requires some experience, especially when using a tow rope. Both drivers should be
familiar with the technique required for towing. Inexperienced drivers should not attempt to tow.
When driving, remember not to pull too hard on the towing vehicle and take care to avoid jerking
movements. When towing on an unpaved road, there is always a risk of overloading and damaging
the anchorage points.
It is still possible to activate the turn signals in a vehicle that is being towed, even if the hazard
warning lights are switched on. To do this, operate the turn signal lever in the required direction
while the ignition is switched on. The hazard warning lights will not flash while the turn signal is
being used. The hazard warning lights will start flashing automatically as soon as the turn signal
lever is moved back to the neutral position.
Notes for the driver of the towed vehicle:
•Leave the ignition of the vehicle being towed switched on to prevent the steering wheel from
locking, to enable the electronic parking brake to be switched off, and to ensure that the turn
signals, wipers and washer system can be used.
•As the power assisted steering does not work if the engine is not running, you will need more
strength to steer than you normally would.
•You will need to depress the brake pedal more vigorously than normal as the brake servo is not
working. Do not drive too close to the towing vehicle.
•Read and comply with the information and notes in the owner's manual of the towing vehicle.
Notes for the driver of the towing vehicle:
•Accelerate carefully and gently. Avoid any sudden driving manoeuvres.
•Brake earlier than normal by pressing lightly on the brake pedal.
•Read and comply with any information and notes in the owner's manual of the towed vehicle.
Checking and refilling
In the engine compartment
The towing eye must always be screwed firmly into the mounting. Otherwise, the towing
eye can be ripped out of the mounting when the vehicle is being tow-started or towed.
NOTICE

Park the vehicle on a level and stable surface.
Depress and hold the brake pedal until you have switched off the ignition.
Switch on the electronic parking brake Electronic parking brake.
Select the neutral position Manual gearbox: selecting a gear or move the selector lever to
position P DSG® dual clutch gearbox.
Switch off the ignition and remove the vehicle key from the ignition lock Starting and
stopping the engine.
Service fluids leaks are harmful to the environment. So you should regularly check the
ground underneath your vehicle. If there are spots of oil or other service fluids on the ground, the
vehicle should be inspected by a qualified workshop. Any spilt service fluids must be disposed of
properly.
Preparing the vehicle for working in the engine compartment
Checklist
The following steps should always be carried out in the specified order before working in
the engine compartment ⇒:
There are rotating components in the engine compartment that can cause serious injury.
•Never place your hand near these components or in the radiator fan. Touching the
rotary blades can result in serious injuries. The fan is temperature-controlled and can
start automatically, even if the ignition has been switched off and the vehicle key has
been removed from the ignition lock.
•If any work has to be performed when the engine is started or with the engine running,
there is an additional, potentially fatal, safety risk from the rotating parts, such as the
poly V-belts, alternator, radiator fan etc., and from the high-voltage ignition system.
Always be particularly careful.
- Always ensure that no body parts, jewellery, ties, loose items of clothing or long
hair can be caught up in rotating engine components. Before starting work,
remove any jewellery and ties, tie up long hair and pull clothes in tightly to avoid
them getting caught in the engine compartment.
- Always take due care and attention when depressing the accelerator. The vehicle
could move, even if the electronic parking brake is applied.
•Always ensure you have not left any objects, such as cleaning cloths and tools, in the
engine compartment. Any forgotten items can cause malfunctions, engine damage and
fires.
WARNING
Additional insulating materials such as covers in the engine compartment could disrupt
the operation of the engine, start fires and lead to severe injuries.
•Never cover the engine with any insulating materials.
WARNING
Service fluids and some materials in the engine compartment are highly flammable and
can cause fires and serious injuries!
•Never smoke in the vicinity of the engine compartment.
•Never work near naked flames or sparks.
•Never spill fluids onto the engine. They could ignite on hot engine components and
hence cause injuries.
•Please note the following when carrying out any work on the fuel system or the
electrical system:
- Always disconnect the 12-volt vehicle battery. Ensure that the vehicle is
unlocked when the 12-volt vehicle battery is disconnected as otherwise the anti-
theft alarm will be activated.
- Never work in the direct proximity of heating systems, water heaters or any other
open flames.
•Always have a fully functional and tested fire extinguisher to hand.
WARNING
When topping up or changing service fluids, ensure that you pour the correct service
fluids into the correct openings. The use of incorrect service fluids could result in serious
malfunctions and engine damage.
NOTICE

Allow the engine to cool sufficiently.
Children and other people should be kept well away from the engine compartment.
Ensure that the vehicle cannot roll away unexpectedly.

•Always follow the instructions in the checklist and observe the general safety
procedures.
WARNING

Display
Fig. 225 On the instrument cluster display: the bonnet is open or not closed properly (illustrationyf.
A symbol in the instrument cluster display ⇒ Fig. 225 indicates if the bonnet is open or is not
closed properly.
Do not drive on! If necessary, lift the bonnet and then close it again.
This symbol is also visible when the ignition is switched off and will go out a few seconds after the
vehicle has been locked when all doors are closed.
The symbol can differ depending on the version of the instrument cluster.
Service fluids and consumables
All service fluids and consumables, e.g. tyres, engine coolant and vehicle batteries, are being
constantly developed. The same applies to toothed belts, engine oils and spark plugs for
combustion engines. For this reason, service fluids and consumables should be replaced at a
qualified workshop. Volkswagen dealerships are kept up to date on all innovations.
If the bonnet is not closed properly, it can open suddenly while you are driving and
completely obscure your view of the road. This can lead to accidents and serious injuries.
•After closing the bonnet, always check that it is properly secured. The bonnet must be
flush with the surrounding body panels.
•If you notice that the bonnet is not closed properly while the vehicle is in motion, stop
the vehicle as soon as possible and close the bonnet.
•Therefore the bonnet should only be opened or closed when you are sure that nobody
is in its path.
WARNING
•The bonnet should only be opened when the wiper arms are flush to the windscreen
and when they are switched off in order to avoid damage to the bonnet and the wiper
arms.
•Always return the wiper arms to the windscreen before starting your journey.
NOTICE
Failure to observe the warning displays could lead to your vehicle breaking down in
traffic, and to accidents and serious injuries.
•Never ignore any warning displays.
•Stop the vehicle as soon as it is possible and safe to do so.
