WARNING

Running-in
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Please follow the regulations concerning running-in new parts.
Running in a new engine
Any new engine has to be run in during the first 1,500 kilometres. During its first few hours of
running, the internal friction in the engine is greater than later on when all the moving parts have
bedded down.
The style of driving during the first 1,500 kilometres will also affect the engine quality. Even after
this time – and especially with a cold engine – drive the vehicle at moderate speeds in order to
reduce engine wear and to increase the mileage that the engine can cover. Do not drive at engine
speeds that are too low. Always shift down gear if the engine is not running smoothly. The
following applies up to 1,000 kilometres:
•Do not depress the accelerator fully.
•Do not drive the vehicle at more than 2/3 of the top engine speed.
From 1,000 to 1,500 kilometres, gradually increase driving performance to top speed and highest
engine speed.
Running in new tyres and brake pads
•New wheels and tyres ⇒ Wheels and tyres
•Information on the brakes ⇒ Braking, stopping and parking
If the engine is run in gently, the life of the engine will be increased and its oil consumption
reduced.

NOTICE
®

You will need an external aerial to use a two-way radio in the vehicle.
Any retrofit installation of electrical or electronic equipment in the vehicle will affect its vehicle type
approval. Under certain circumstances, this can negate the type approval for the vehicle.
Volkswagen has approved the vehicle for use with two-way radios subject to the following
conditions:
•Correct installation of external aerial.
•A maximum transmitting power of 10 watts.
An external aerial is needed to give the equipment its optimal range.
Check first with a qualified workshop if you wish to use a two-way radio with a transmitting power of
over 10 watts. A qualified workshop is familiar with the technical options for retrofitting. Volkswagen
recommends using a Volkswagen dealership for this purpose.
Please observe legislation and the instructions and information given in the operating manuals for
radio equipment.
Information stored in the control units
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Your vehicle is factory fitted with electronic control units which are responsible for engine and
gearbox management. The control units also monitor the function of the exhaust system and the
airbags.
These electronic control units continuously evaluate data relevant to the vehicle while the vehicle is
being driven. Only these data will be stored if there are any faults recorded or any deviations from
the specified values. This is generally displayed by the indicator lamps on the instrument cluster.
Special units are required to read and evaluate data stored in the control units.
These data are stored so that specialist workshops can diagnose and solve problems. The
following data may have been stored:
•Engine and gearbox-relevant data.
•Speed.
•Direction of travel.
•Braking power.
•Seat belt monitor.
The control units never record conversations that take place in the vehicle. It is neither possible nor
permitted to use the stored data to create movement profiles.
When the vehicle is being used, situations may arise in which the stored data (alone or in
conjunction with other information such as accident reports, vehicle damage, witness statements
etc.) can become assignable to a particular person, in which case it may be necessary to consult an
expert and use the expert's information.
In vehicles with an emergency call function via a mobile telephone or other units, the current
location can be transmitted. In the event of an accident in which the control units register that an
airbag has been triggered, the system can automatically send out a signal. This depends on your
service provider. Transmission is possible only in areas with a sufficiently strong mobile telephone
signal.
Additional functions that are contractually agreed with the customer, e.g. vehicle positioning in an
emergency, allow certain vehicle data to be transmitted from the vehicle.
If radio equipment is not secured or not properly secured in the vehicle, it could be flung
though the interior during a sudden driving or braking manoeuvre, or in the event of an
accident. This can cause injuries.
•While the vehicle is in motion, always secure two-way radios properly outside the airbag
deployment zones or stow them away safely.
WARNING
If two-way radios that are not connected to an external aerial are used, electromagnetic
radiation in the vehicle could exceed limit values and thus be a health hazard for drivers and
other vehicle occupants. This also applies to external aerials that have not been correctly
installed.
•Two-way radios should only be used in the vehicle if an external aerial is properly
connected.
CAUTION

Event data recorder
The vehicle is not fitted with an event data recorder.
Event data recorders temporarily store vehicle information. This provides precise information in the
event of an accident. In vehicles with an airbag system, data that might be relevant in the event of
an accident can be stored, e.g. impact speed, belt buckle status, seat positions and trigger speed.
The scope of the data is manufacturer-specific.
An event data recorder may only be fitted if the owner has approved the procedure. This is covered
by legislation in some countries.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions,
such as lane change flash, single door unlocking and displays, can be reprogrammed using special
workshop equipment. If this is the case, the descriptions in your vehicle wallet will no longer
correspond with the original functions. Volkswagen recommends that you have any reprogramming
confirmed in the service schedule under Workshop comments.
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Reading the vehicle's event memory
A diagnostic interface for reading the event memories is located in the vehicle interior ⇒. Data
relating to the function and status of the electronic control units are stored in the event memory.
Additional information on the stored data is available from qualified workshops.
The diagnosis interface is located behind near the fuse box in the footwell on the driver side.
The event memory should only be read and reset by a qualified workshop.
After a fault has been rectified, the information in the memory pertaining to the fault is deleted.
Other memory content is overwritten on an on-going basis.
Using a mobile telephone in the vehicle without a connection to the
external aerial
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Both during telephone calls and in standby mode, mobile telephones transmit and receive radio
waves, which may also be termed "high-frequency energy". Current scientific literature warns us
that radio waves can be harmful to human beings if they exceed certain limits. Government bodies
and international committees have introduced threshold values and guidelines to ensure that
electromagnetic radiation produced by mobile telephones does not pose a hazard to health.
However, there is no proven scientific evidence that demonstrates that cordless telephones are
absolutely safe.
For this reason, some experts are calling for more precautions to be taken in the use of mobile
telephones, by taking steps to reduce the level of personal exposure to electromagnetic radiation.
If a mobile telephone that is not connected to the vehicle's external aerial is used inside the vehicle,
the level of electromagnetic radiation could be higher than when the mobile telephone is connected
to an integrated aerial or any other external aerial.
If the vehicle is fitted with a suitable hands-free unit which enables the use of innumerable
additional functions of Bluetooth compatible mobile telephones, this will satisfy the legal
requirements in many countries which permit the use of a mobile telephone in a vehicle only if a
hands-free unit is used.
The hands-free system of the portable navigation device (delivered by Volkswagen) in your vehicle
has been developed for mobile telephones that are compatible with Bluetooth⇒ Portable
navigation device. Mobile telephones must be located in a suitable telephone holder or be stored
securely in the vehicle. If a telephone holder is used it must be securely attached to the base plate.
This is the only way to ensure that the mobile telephone is securely attached to the dash panel and
always within reach of the driver. Depending on the hands-free system, the connection between the
mobile telephone and the external aerial is established either via the telephone holder or via an
existing Bluetooth connection between the mobile telephone and the vehicle.
Connecting the mobile telephone is to a telephone aerial integrated in the vehicle or to an external
telephone aerial reduces the electromagnetic radiation generated by the telephone which could
affect the human body. Using an aerial also improves the quality of the signal.
Incorrect use of the diagnostic interface can cause faults, which can result in accidents and
serious injuries.
•Never read the event memory using the diagnostic interface yourself.
•The diagnostic interface should only be read by a qualified workshop.
WARNING
®
®
®

If a mobile telephone is used in the vehicle interior without this hands-free system, it is not safely
secured in the vehicle and also not connected to the vehicle's external telephone aerial.
Furthermore, the mobile telephone is not being charged in the telephone holder. It is also likely that
the telephone connection will be disrupted and the signal strength will be poor.
A mobile telephone should only be used in the vehicle if it is connected to a hands-free unit.
Volkswagen recommends the use of an external aerial when using a mobile telephone in the
vehicle.
