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.
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?

Driver assistance systems
● Will the navigation system fitted at the fac-
tory operate correctly in the destination coun-
try with the available navigation data?
● Are special tyres required in the destination
country? CAUTION
SEAT does not accept liability for any damage
to the vehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving along flooded roadways
To prevent damage to the vehicle when driv-
ing through water, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded zone. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or switch off the engine.
● Oncoming traffic will cause waves which
raise the level of the water, making it difficult
to cross the water.
● Disconnect the Start-Stop system whenever
crossing water. WARNING
When driving through water, mud, melted
snow, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “Dry the brakes and remove ice” by braking
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeuvres. CAUTION
● Driving through flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses corrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. Driver assistance systems
Braking and stability systems Brake assist systems The assisted braking systems ESC*, ABS,
EBV, BAS, ASR, TC and EDL only operate when
the ignition is switched on. They contribute
significantly to increasing active safety.
Electronic stability control (ESC)*
ESC* reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions.
ESC* detects critical handling situations,
such as understeer, oversteer and wheelspin
on the driven wheels. The system stabilises
the vehicle by braking individual wheels or
by reducing the engine torque.
The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sudden-
ly then ESC* will not be useful in all cases. If
the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC* will
not provide assistance in the same way as on
dry ground. If the vehicle loses its grip on the
ground and moves on a film of water (“aqua-
planing”), the ESC* will not be able to help

and serious injury to the driver and passen-
gers.
●
Adjust your speed and driving style to visi-
bility, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC* provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
laws of physics. Even with ESC* and other
systems, slippery and wet roads will always
be dangerous.
● Driving to quickly on wet ground can result
in the wheels losing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely effective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for example on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. WARNING
The effectiveness of the ESC* can be consid-
erably reduced if other components and sys-
tems affecting driving dynamics are not main-
tained or are not functioning correctly. This
includes, among others, brakes, tyres and
other systems already mentioned.
● Remember that changing and fitting other
components to the vehicle can affect opera-
tion of the ABS, BAS, ASR TC, EDL and ESC*.
● Changes to the vehicle suspension or using
unapproved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASR, TC, EDL
and ESC* and their effectiveness.
● Likewise, the effectiveness of ESC* de-
pends on the use of suitable tyres
››› page 158. Note
● To ensure that the ESC*, ASR and TC work
properly, all four wheels must be fitted with
identical tyres. Any differences in the rolling
radius of the tyres can cause the system to
reduce engine power when this is not de-
sired.
● If a malfunction should occur in the ABS,
the ESC*, ASR, TC and EDL will also be affec-
ted.
● Noises may be heard while any of the
above systems are operating. Parking sensor system*
Introduction The parking sensor system assists the driver
when parking. If the rear of the vehicle is ap-
proaching an obstacle, an intermittent audi-
ble warning is emitted. The shorter the dis-
tance, the shorter the intervals between
tones. If the vehicle is too close to the obsta-
cle, the audible warning becomes constant.
If you continue to approach an obstacle when
the sound is continuous, this means the sys-
tem can no longer measure the distance.
Sensors situated on the rear bumper transmit
and receive ultrasound. Using the ultrasound
signal (transmission, reflection from the ob-
stacles and reception), this system continu-
ously calculates the distance between the
bumper and the obstacle.
WARNING
The parking distance warning system cannot
replace the driver's assessment of the situa-
tion.
● The sensors have blind spots in which ob-
stacles and people are not registered.
● Always observe the area around the vehi-
cle, as the sensors do not always detect
small children, animals or objects. » 105Technical specifications

manently informed of any modifications. WARNING
The incorrect use or handling of fluids or con-
sumables may result in accident, serious in-
jury, burns or intoxication.
● Therefore, fluids must always be stored
closed in their original 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
reach of children.
● Read and observe the information and
warnings given on the fluid containers.
● Only work in the open air or in well-ventila-
ted zones, 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 use 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 great strain in high outside tempera-
tures, it could overheat.
