verified. They will switch off after a few sec-
onds.
CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle. Note
While the control lamps  or
 maintain lit
up, the engine will present faults, a higher consumption of fuel and a loss of engine
power.
Catalytic converter
The catalytic converter permits the subse-
quent treatment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil
››› page 146 .
● Do not t

ow-start the vehicle; use the starter
cables ››› page 181.
If

you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur under certain conditions. This de- pends on the sulphur content of the fuel
used.
Driving abroad
In some countries, certain safety regulations
and requirements are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
●
Does the vehicle need technical modifica-
tions for driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostics equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion country?
● For petrol vehicles: Is unleaded petrol avail-
able at the right octane rating?
● For diesel engines: is diesel fuel available
with a low sulphur content?
● Are a suitable engine oil ( ››› page 146) and
other engine fluids complying with SEAT
specifications available in the destination
country?

Operation
WARNING
Use of the cruise control could cause acci-
dents and severe injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the distance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpaved roads.
● Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
control system, turn it off every time you fin-
ish using it. ●
It is dangerous to use a set speed which is
too high for the prevailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a constant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Control lampIt lights

This cruise control system maintains the
set speed of the vehicle. Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
WARNING
If the warning lamps are ignored, the vehicle
may stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps. CAUTION
Failure to heed the warning lamps when they
appear may result in faults in the vehicle. 108

ness.
●
Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● The City Safety Assist function does not re-
act to people, animals or vehicles that cross
or move in the opposite direction in the same
lane.
● If after switching on the City Safety Assist
function the vehicle begins to move, slow the
vehicle with the foot brake. CAUTION
If you suspect that the City Safety Assist ra-
dar feature is damaged, switch it off. This will
avoid additional damage.
● Any repair of the radar sensor requires spe-
cialist knowledge. SEAT recommends taking
your car in for technical service. Note
● If the City Safety Assist function activates a
brake, the brake pedal range is reduced. This
makes the brake pedal seem “harder”.
● Automatic brake intervention by the City
Safety Assist function can be cancelled by
pressing the clutch pedal, the accelerator
pedal or by a corrective intervention.
● During automatic braking by the City Safety
Assist function you may hear unusual noises. This is normal and is produced in the brake
system.

Care and maintenance
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 position, 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 exterior 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 vehicle if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
units
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 vehicle 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 vehicle 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-
c or
der.
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 »
