WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Always observe any lit warning lamps.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle.
Note
On the display of the Portable Navigation System (supplied by SEAT)
⇒ page 222 an engine coolant temperature gauge can be seen. 
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25 °C (-13 °F) and protects the light alloy parts of the cooling system
against corrosion. It also prevents scaling and considerably raises the boil-
ing point of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture of
distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒ 
.
WARNING
If there is not enough anti-freeze in the coolant system, the engine may
fail leading to serious damage.
● Please make sure that the percentage of additive is correct with re-
spect to the lowest expected ambient temperature in the zone in which
the vehicle is to be used.
● When the outside temperature is very low, the coolant could freeze
and the vehicle would be immobilised. In this case, the heating would
not work either and inadequately dressed passengers could die of cold.
CAUTION
The original additives should never be mixed with coolants which are not
approved by SEAT. Otherwise, you run the risk of causing severe damage to
the engine and the engine cooling system.
● If the fluid in the expansion tank is not purple but is, for example,
brown, this indicates that the G 13 additive has been mixed with an inade-
quate coolant. The coolant must be changed as soon as possible if this is
the case! This could result in serious faults and engine damage.
For the sake of the environment
Coolants and additives can contaminate the environment. If any fluids are
spilled, they should be collected and correctly disposed of, with respect to
the environment. 

Vehicle care and maintenance
In vehicles equipped with an emergency call function via the mobile tele-
phone or other appliances connected in the vehicle, it is possible to send
the vehicle position. If the control unit records an accident with airbag acti-
vation, the system may automatically send a signal. This will depend on the
network operator. Normally, transmission is only possible in areas with
good coverage.
Event Data Recorder
The vehicle is not fitted with an event data recorder.
An event data recorder temporarily stores the vehicle information. There-
fore, in the event of accident, it is possible to obtain detailed information
about how the accident occurred. For example, in vehicles with airbag sys-
tems, data relating to speed of impact, seat belt status, seat positions and
airbag activation times may be stored. The volume of data depends on the
manufacturer.
Event data recorders can only be mounted with authorisation from the vehi-
cle owner and, in some countries, they are governed by local legislation.
Reprogramming control units
On the whole, all the data required for the component management is stor-
ed in the control units. The programming of certain convenience functions,
such as the convenience indicators, individual door opening and instruc-
tions on the display can be modified using special equipment at the work-
shop. If the comfort functions are reprogrammed, the information and In-
struction Manual descriptions will not coincide with the modified functions.
Therefore, SEAT recommends that any modifications are recorded in the sec-
tion “Other workshop notes” in the Maintenance Programme.
The SEAT Official Service must have a record of any modification to the pro-
gramming.
Reading the vehicle fault memory
There is a diagnostics connector in the vehicle interior for reading the vehi-
cle fault memory. The fault memory documents errors and deviations from
the theoretical values of the electronic control units. The diagnostics connector is in the driver side footwell area, next to the lev-
er for opening the bonnet, below a cover.
The fault memory should only be read and reset by a Specialised workshop.

Using a mobile telephone in a vehicle without connection
to an exterior aerial
Mobile telephones transmit and receive radio waves also called high-fre-
quency energy, both when in use and when on stand-by. Scientific studies
state that radio waves exceeding certain values may be harmful to the hu-
man body. International committees and authorities have established limits
and directives in order to ensure electromagnetic radiation from mobile
phones remains within certain limits that do not endanger human health.
However, there is no available conclusive scientific evidence that cordless
phones are completely safe.
That is why some experts recommend moderate use of the mobile tele-
phone, and the appliance of measures to reduce radiation on the human
body.
When a mobile telephone not connected to an exterior aerial is used inside
the vehicle, the electromagnetic radiation may be greater than if the mobile
phone were connected to a built-in aerial or to another exterior aerial.
If the vehicle is fitted with a suitable hands-free device that allows the em-
ployment of numerous additional mobile telephone functions with compati-
ble Bluetooth technology ®
, it will comply with the legislation in many coun-
tries which only permits the use of mobile phones inside vehicles using a
hands-free device.
The hands-free system of the Portable Navigation System (supplied by
SEAT) has been designed for use with conventional mobile phones and
phones with Bluetooth technology ®
⇒ page 229. Mobile telephones must
be placed in a suitable telephone support or stored safely in the vehicle. If a
support is used for the telephone, it must be securely fastened to the base 

plate. The mobile will be secure on the instrument panel and always within
reach of the driver only by following these procedures. Mobile telephone
connection with an external aerial is carried out subject to the hands-free
device, via the telephone support or by the Bluetooth ®
connections present
in the mobile telephone and the vehicle.
If the mobile telephone is connected to an aerial incorporated into the vehi-
cle or an exterior aerial connected to the vehicle, this will help to reduce the
electromagnetic radiation transmitted and the risk to human health. It will
also improve the quality of the connection.
If the mobile telephone is used inside the vehicle without the hands-free
system, it will not be securely fastened and will not be connected to the ex-
terior aerial of the vehicle telephone. Nor will the telephone charge if it is
not on the support. In addition, some calls may break off and the quality of
the connection will be affected.
Mobile telephones should only be used inside the vehicle if they are con-
nected to a hands-free system. SEAT recommends using an external aerial
should you wish to use a mobile telephone inside the vehicle.

WARNING
If the mobile telephone is not securely fastened in position, it could be
sent flying around the vehicle in the event of sharp braking, sudden ma-
noeuvres or accident, causing injury.
● While driving, the mobile telephone, other equipment including tele-
phone accessories such as telephone supports, notepads and navigators
must be correctly secured, away from the airbags deployment zones, or
stored in a safe place.
WARNING
When using a mobile telephone or two-way radio without connecting an
external aerial, the maximum permitted levels of electromagnetic radia-
tion in the vehicle may be exceeded, thus putting the driver and the rest
of the vehicle occupants in danger. This is also the case if the aerial has
not been correctly installed.
● A minimum of 20 centimetres should be kept between mobile tele-
phone aerials and artificial pacemakers, as mobile telephones may affect
the working of pacemakers.
● Do not carry a mobile telephone in your breast pocket directly over
the pacemaker when the mobile telephone is switched on.
● Immediately switch off the mobile telephone if you suspect any inter-
ference with pacemakers or other types of medical equipment.
