230, 115 or 100 V150 W (300 W peak poweryf
If two or more devices are connected at the same time, the overall power consumption of all
connected electrical devices must never exceed 190 watts ⇒.
The maximum power rating of the individual sockets should never be exceeded. The power rating
of each device is stated on its type plate.
230-volt socket, 115-volt socket, 100-volt socket
The socket is activated automatically as soon as a plug is connected when the engine is running. If
there is sufficient energy in the system, the socket can also be used when the engine is off ⇒.
Connecting an electrical device: fold open the cover and insert the plug all the way into the socket
to unlock the integrated child lock. Electricity will not flow until the child lock has been unlocked.
LEDs on the socket
Constant green light:The child lock is disengaged. The socket is ready for use.
Flashing green light:
The ignition is switched off but there is sufficient energy available
to continue to supply the socket with power for up to 10 minutes.
If the plug is removed during this time, the socket switches off
and cannot be re-used until the ignition is switched on again.
Flashing red light:A fault has occurred, for example cut-off due to excess current or
temperature.
Temperature switch-off
If a specific temperature is exceeded, the inverter of the 230-, 115- or 100-volt socket switches itself
off automatically. The switch-off function prevents the connected device from overheating when the
power consumption is too high or if the ambient temperature is too high. The 230-, 115- or 100-volt
socket can be used again only after a cool-down phase.
The plug on the connected device must first be removed and then reinserted before using the 230-,
115- or 100-volt socket again after the cool-down phase. This prevents the electrical devices being
switched on again unintentionally.

•If necessary, fold back the rear seat backrest and allow it to engage securely.
•If necessary, adjust the headlight range ⇒ Headlights.

Objects that are not secured, or are secured incorrectly, can cause serious injuries in the
event of a sudden driving or braking manoeuvre or accident. This applies particularly if
objects are struck by the airbag when activated and then flung through the vehicle
interior. To reduce the risk of accidents, please observe the following guidelines:
•Always stow all objects in the vehicle securely.
•Small and light objects should also be secured.
•Objects should be stowed in the vehicle interior in such a way that they can never
enter the airbag deployment zones while the vehicle is in motion.
•Always keep stowage compartments closed while the vehicle is in motion.
•Stowed objects must never cause passengers to assume an incorrect sitting position.
•If an item is being stowed on a seat, this seat must not be used by any passengers.
•Do not stow any hard, heavy or sharp objects loose in any of the vehicle's open
stowage areas, on the surface behind the rear seat backrest or on the dash panel.
•Remove any hard, heavy or sharp objects from items of clothing and bags inside the
vehicle and stow them securely.
WARNING
Transporting heavy objects changes the vehicle's handling and increases the braking
distance. Heavy loads that are not properly stowed or secured in the vehicle can lead to a
loss of vehicle control and can cause serious injury.
•Never exceed the vehicle's maximum payload. Both the payload and the distribution of
the load in the vehicle will have an effect on the driving response and braking distance
of the vehicle.
•Transporting heavy objects changes the vehicle's handling and the centre of gravity.
•The payload should be distributed as evenly as possible in the vehicle.
•Always secure heavy objects in the luggage compartment as far in front of the rear axle
as possible.
•Loose objects in the luggage compartment can suddenly slide and change the way the
vehicle handles.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•Accelerate carefully and gently.
•Avoid sudden braking and driving manoeuvres.
•Brake earlier than in normal driving.
WARNING
Objects rubbing against the rear windows may damage or destroy the heating wires or,
depending on the vehicle equipment, also the aerial.
NOTICE

Trailer towing
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Headlight adjustment
Towing a trailer can raise the front end of the vehicle enough for the dipped beam to blind other
road users. Use the headlight range control to lower the light cone as required. Vehicles with
automatic headlight range adjustment are adjusted automatically.
Things to note when driving with a trailer
•If the trailer has an overrun brake, apply the brakes gently at first and then firmly. This will
prevent the jerking that can be caused by the trailer wheels locking.
•The combination weight causes the braking distance to increase.
•Engage a lower gear prior to inclines (manual gearbox or Tiptronic mode of the automatic
gearboxyfWRDGGLWLRQDOO\PDNHXVHRIHQJLQHEUDNLQJ7KHEUDNHV\VWHPFRXOGRWKHUZLVH
overheat and fail.
•The vehicle's centre of gravity and, in turn, the vehicle's handling, will change because of the
trailer load and the increased combined towing weight of the vehicle and trailer.
•The weight distribution of a loaded trailer with an unladen towing vehicle is very unfavourable.
When driving in this situation, drive particularly carefully and slowly.
Pulling off on slopes when towing a trailer
A vehicle towing a trailer is liable to roll back a short distance when moving off on a slope,
depending on the angle of the slope and the total weight of the trailer and vehicle.
When towing a trailer, pull off on slopes as follows:
•Depress and hold the brake pedal.
•Press button once to switch off the electronic parking brake ⇒ Electronic parking 
brake.
•Manual gearbox: depress the clutch fully.
•Select first gear ⇒ Manual gearbox: selecting a gear or selector lever position D/S⇒ DSG dual 
clutch gearbox.
•Pull on the button and hold it in this position to hold the vehicle and trailer with the
electronic parking brake.
•Release the brake pedal.
•Pull away slowly. To do this, slowly release the clutch pedal for a manual gearbox.
•Only let go of the button when the engine has sufficient power to move off.
Trailer stabilisation
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The trailer stabilisation function can detect if an attached trailer is starting to lurch from side to side
and can provide countersteer.
Trailer stabilisation is a subsidiary function of the Electronic Stability Control (ESCyf.
®
Incorrect trailer towing can cause loss of vehicle control and serious personal injury.
•Towing a trailer and transporting heavy or bulky items can change the way the vehicle
handles and increase the braking distance.
•Always drive carefully and think ahead. Brake earlier than in normal driving.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions. Reduce your speed, particularly when going downhill.
•Accelerate carefully and gently. Avoid abrupt and sudden driving and braking
manoeuvres.
•Take special care when overtaking. Reduce your speed immediately if the trailer shows
even the slightest sign of snaking.
•Never try to stop a trailer from snaking by increasing your speed.
•Keep to speed limits which may be lower for vehicles with trailers than for vehicles
without trailers.
WARNING

Volkswagen recommends having the towing bracket retrofitted by a qualified workshop. The cooling
system may need to be modified or heat shields may need to be fitted. Volkswagen recommends
using a Volkswagen dealership for this purpose.

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.
