Other vehicles changing lanes The City Safety Assist function is limited by
the l
a
w

s of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
For example, the following driving situations
require special attention:
Driving through a bend
When entering or leaving a “long” bend, the
vehicle may decelerate when the laser sensor
detects a vehicle travelling in the opposite
lane ››› Fig. 156 A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehi-
cles in front if they are in the sensor's detec-
tion zone ››› Fig. 156 B. This applies especial-
ly to narrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system ›››
Fig. 157. To inter-
rupt deceleration you can accelerate, turn the
steering wheel or press the clutch. »

Care and maintenance
consumables should be changed at a speci-
ali sed w
ork
shop. Technical services are per-
manently informed of any modifications. WARNING
The incorrect use or handling of fluids or con-
sum ab

les may result in accident, serious in-
jury, burns or intoxication.
● Therefore, fluids must always be stored
closed in their origin
al container.
● Never store fluids in empty food containers
or bottles
as other people may accidentally
drink the fluid.
● Keep all fluids and consumables out of
reac
h of children.
● Read and observe the information and
warning
s given on the fluid containers.
● Only work in the open air or in well-ventila-
ted z
ones, when using products which give
off harmful vapours.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid in the main-
tenance of the vehicle. These are toxic and
highly flammable. They could lead to fire or
explosions! CAUTION
● Only u

se appropriate fluids. Do not confuse
fluids as this can cause serious malfunctions
or engine damage.
● Accessories and other components moun-
ted in front
of the air inlet reduce the cooling effect of the coolant. If the engine is running
under gr
e

at strain in high outside tempera-
tures, it could overheat. For the sake of the environment
Leaking fluids could pollute the environment.
C o l

lect any spilt fluids in suitable containers
and dispose of them in accordance with legis-
lation and with respect for the environment. Repairs and technical changes
When performing repairs and technical mod-
ific
ation
s,

SEAT's directives must be ob-
served! ››› Unauthorised modifications to the electronic
c
omponents
or sof

tware in the vehicle may
cause malfunctions. Due to the way the elec-
tronic components are linked together in net-
works, other indirect systems may be affec-
ted by the faults. This may significantly affect
the vehicle's performance, increase compo-
nent wear and could mean that the vehicle
registration documents are no longer valid.
Your SEAT Official Service cannot be held lia-
ble for any damage caused by technical mod-
ifications or repairs performed incorrectly.
The SEAT Official Service does not accept lia-
bility for damage resulting from technical
modifications or repairs performed incorrect- ly; neither is the SEAT warranty valid in these
case

s.
SEAT recommends you have any technical
modifications or repairs performed at a SEAT
Official Service and that you use genuine
SEAT spare parts ®
.
Vehicles with special accessories and equip-
ment
The manufacturers of additional equipment
guarantee that the equipment complies with
applicable laws and regulations with respect
to the environment, in particular Directives
2000/53/CE and 2003/11/CE. The first direc-
tive governs the disposal of end-of-life vehi-
cles while the second refers to the restric-
tions on the marketing and use of certain
dangerous substances and preparations.
The vehicle owner should keep the documen-
tation for the additional equipment safely
and hand it over to the scrap yard at the end
of the vehicle's service life. This ensures that
any additional equipment mounted in end-of-
life vehicles is correctly disposed of with re-
spect for the environment. WARNING
Repairs or modifications which are not per-
formed c orr

ectly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the driver assist systems. This
could result in serious accident. » 165

Care and maintenance
The optimal reach of the equipment is only
ac hiev
ed w
ith an external aerial.
Check first with a specialised workshop that
understands the technical possibilities of in-
stallation if you wish to use a two-way radio
with a transmitting power of over 10 watts.
SEAT recommends taking your car in for tech-
nical service.
All legal requirements, together with the in-
structions for the use of two-way radios must
be observed. WARNING
If the two-way radio is not securely fastened
in pos ition, it

could be sent flying around the
vehicle in the event of sharp braking, sudden
manoeuvres or accident, causing injury.
● While driving, two-way radios must be se-
curely
fastened in position, outside the air-
bags deployment zones, or safely stowed
away. WARNING
When using a two-way radio without a con-
nection to an e xt

erior aerial, the maximum
permitted levels of electromagnetic radiation
may be exceeded. This is also the case if the
aerial has not been correctly installed.
● You should only use a two-way radio inside
the vehic
le if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
u
nit
s Your vehicle is fitted at the factory with a ser-
ies
of

electronic control units responsible for
the engine and gearbox management. In ad-
dition, the control units supervise the per-
formance of the exhaust gas system and the
airbag systems.
Therefore, while the vehicle is being driven,
these electronic control units are continuous-
ly analysing the vehicle data. In the event of
faults or deviations from the theoretical val-
ues, only this data is stored. Normally, the
warning lamps on the instrument panel light
up in the event of faults.
This data can only be read and analysed us-
ing special equipment.
The storing of the data allows specialised
workshops to detect and repair faults. Stored
data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The v ehic

le control units never record conver-
sations held by passengers in the vehicle.
In vehicles equipped with an emergency call
function via the mobile phone or other appli- ances connected in the vehicle, it is possible
to send the v

ehicle position. If the control
unit records an accident with airbag activa-
tion, the system may automatically send a
signal. This will depend on the network oper-
ator. Normally, transmission is only possible
in areas with good coverage.
Event Data Recorder
The vehicle is not fitted with an event data re-
corder.
An event data recorder temporarily stores the
vehicle information. Therefore, in the event of
an accident, it is possible to obtain detailed
information about how the accident occur-
red. Vehicles with airbag systems can store
data relating to impact speed, seat belt sta-
tus, seat positions and airbag activation
times may be stored, etc. The volume of data
depends on the manufacturer.
Event data recorders can only be mounted
with authorisation from the vehicle 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 stored in the con-
trol units. The programming of certain con-
venience functions, such as the turn signals,
individual door opening and instructions on
the display can be modified using special »

When using a mobile telephone or two-way
r a dio w

ithout connecting an external aerial,
the maximum permitted levels of electromag-
netic radiation in the vehicle may be excee-
ded, 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
