Insert the cigarette lighter back into the socket.

WARNING
Improper use of the cigarette lighter can cause fires, burns and other serious injuries.
Always use the cigarette lighter properly, and only use it to light tobacco products.
Never leave children unsupervised in the vehicle. The cigarette lighter can be used when the ignition
is switched on.

The cigarette lighter socket can also be used as a 12-volt socket ⇒ Electrical sockets .
Electrical sockets
Introduction
This chapter contains information on the followingsubjects:
⇒ Electrical sockets in the vehicle 
Electrical equipment can be connected to the sockets in the vehicle.
The electrical devices must be in good condition. Do not use faulty devices.
The 12-volt socket will work only when the ignition is switched on.

WARNING
Improper use of the sockets and electrical accessories can cause fires and severe injuries.
Never leave children unsupervised in the vehicle. Sockets and the devices connected to them can be
used when the ignition is switched on.
If the electrical device gets too hot, switch off the device immediately and disconnect it from the
socket.

NOTICE
In order to prevent damage to the electrical system, never connect equipment that supplies electric
power, such as solar panels or battery chargers for charging the 12-volt battery, to the 12-volt
socket.
Use only electrical devices that have been approved in accordance with current guidelines
concerning electromagnetic compatibility.
In order to avoid damage due to voltage fluctuations, always switch off any electrical devices before
switching the ignition on or off and before starting the engine. When the start/stop system

automatically switches off and restarts the engine, it is not necessary to switch off any connected
electrical consumers.
Never connect electrical devices requiring more than the rated power to a 12-volt socket. The
vehicle's electrical system can be damaged if the maximum power consumption is exceeded.
Observe the operating instructions of the electrical devices!

Using electrical consumers with the engine switched off and the ignition switched on will drain the
12-volt battery.

Unshielded devices can cause interference in the Infotainment system and vehicle electronics.
Electrical sockets in the vehicle

Maximum power rating
Electrical socket Maximum power rating
12 volts 120 watts
The maximum power rating of the individual sockets must never be exceeded. The power rating of
each device is stated on its type plate.
If there are several sockets in the vehicle and two or more devices are connected at the same time,
the overall power consumption of all connected electrical devices must never exceed 190 W ⇒ .

Before using the Volkswagen Car-Net services for the first time, please read and observe the
information in the relevant service description. This will quickly help you to become familiar with the
services and make you aware of potential risks to yourself and others, and how to avoid them.

WARNING
Accidents and injuries can occur if the driver is distracted.
Always drive carefully and responsibly.

WARNING
Failure to observe the information in the service description can lead to your vehicle breaking down
in traffic, and can cause accidents and serious injuries.
Always use the most up-to-date edition of the relevant service descriptions which is available on the
Volkswagen website.

WARNING
The following conditions can make it impossible to make a telephone call, run a Volkswagen Car-Net
service or transfer data:
If your current location is in an area with no or insufficient mobile communications and GPS
reception. This can also include tunnels, streets with tall buildings, garages, multi-storey car parks,
underpasses, mountains and valleys.
If you are in an area with sufficient mobile communications and GPS reception but the
telecommunications provider's mobile network is overloaded, out of order or unavailable.
If the components in the vehicle required for the services and data transmission are damaged, not
working or do not have sufficient electrical power.
The battery for the mobile device is empty, does not have a sufficient charge level or has no more
call credit.

WARNING
Using computers and mobile devices in public or non-secured LAN and WLAN networks can lead to a
loss of control over your Volkswagen Car-Net services.
In addition to the usual precautionary measures to be taken when using the Internet, you should
protect your computer and mobile device with suitable anti-virus software and regularly update its
signatures.

If you park the trailer using the support wheel or other trailer supports, the trailer must be
unhitched from the vehicle. The vehicle could move up and down if the load changes or if there is
damage to the tyres, for example. If this happens, a great deal of force will be exerted on the towing
bracket and trailer, which could lead to damage to the vehicle and trailer.

If there is a fault in the vehicle or trailer electrical systems or in the anti-theft alarm, have the vehicle
checked by a qualified workshop.

If the 12-volt vehicle battery charge level is low, the electrical connection to the trailer will be
interrupted automatically.
Loading the trailer
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Trailer weight and drawbar load
The trailer weight is the weight that the vehicle can pull ⇒ .
The drawbar load is the load that is exerted vertically from above onto the ball head of the towing
bracket.
The figures for trailer weights and drawbar weights that are given on the data plate of the towing
bracket are for certification purposes only. The correct values for your specific model, which may be
lower than these figures, are given in the vehicle registration documents. All data in the official
vehicle documents take precedence over these data.
The maximum permitted drawbar load exerted by the trailer drawbar on the ball head of the towing
bracket must not exceed 80 kg.
In the interest of driving safety, Volkswagen recommends that you always use the maximum
drawbar load. The handling of the vehicle combination will be impaired if the drawbar load is too
low.
The drawbar load increases the weight on the rear axle and reduces the maximum payload of the
vehicle as a result.
Gross combination weight
The gross combination weight is made up of the actual weight of the loaded vehicle and of the
loaded trailer.
In some countries, trailers are divided into different classes. Volkswagen recommends that you
contact a qualified workshop to find out about suitable trailers.
Loading the trailer
The weight of the load should be distributed evenly. The maximum permitted drawbar load should
be utilised. Do not place the load only at the front or the rear of the trailer:

Introduction

⇒ Jump lead connection point (earth connection) 
⇒ Jump starting the vehicle 
If the engine fails to start because the 12-volt vehicle battery is flat, the discharged battery can be
connected to the 12-volt battery of another vehicle to start the engine.
Suitable jump leads are needed for jump starting.

The discharged 12-volt vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are
connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about a minute.
If the engine still does not start, seek expert assistance.
Attaching the jump leads
The jump leads should be connected only in the order A – B – C – D⇒ Fig. 177 .
The black jump lead should never be connected to the negative terminal (–) on the 12-volt vehicle
battery. Connecting the lead to the negative terminal can cause incorrect condition evaluation of the
12-volt vehicle battery in the vehicle electronics.

NOTICE
When filling or changing service fluids, please ensure that the correct service fluids are filled through
the correct openings. The use of incorrect service fluids could result in serious malfunctions and
engine damage.

Service fluids that leak from the vehicle are harmful to the environment. For this reason, you should
regularly check the ground underneath your vehicle. If there are spots of oil or other fluids on the
ground, the vehicle should be inspected by a qualified workshop. Any spilt service fluids must be
disposed of properly.
