Operation
road before ESC* can intervene then the sys-
t em c
annot
provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock system (ABS)
ABS can prevent the wheels from locking dur- ing braking until just before the vehicle stops
thus helping the driver to steer the vehicle
and maintain control. This means that, even
during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remov
e your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
brakin
g force!
● Maintain vehicle direction when braking
ful
ly.
● When the brake pedal is released or when
the brake f
orce is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
expect the ABS to reduce the braking dis-
tance under any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground. Brake assist system (BAS)
The brake a

ssist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the
ABS to be activated more quickly and effec-
tively.
¡Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control system (ASR) or Traction
Control (TC)*
In the event of wheelspin, the traction control
system ASR or TC reduces the engine torque
to match the amount of grip available. The
ASR or TC makes some situations easier, for
example, when starting, accelerating or go-
ing uphill, even in unfavourable road condi-
tions.
Electronic differential lock (EDS)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel
and directs the power to the other one. To prevent the disc brake of the braked wheel
from ov
erheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or wet
grou nd c

an result in loss of vehicle control
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
law
s 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 lo
sing 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. 1)
Depending on the version.

Operation
●
Alw a
ys adapt your driving style to suit the
flow of traffic.
● Only use the kick-down function or rapid
accel
eration if visibility, weather, road and
traffic conditions so permit.
● Never put other road users in danger by ac-
celer
ating or with your driving style. CAUTION
If you stop on a hill with a gear range engag-
ed, do not try

to prevent the vehicle from roll-
ing back by pressing on the accelerator. Oth-
erwise, the automatic gearbox may overheat
causing damage. Automatic gearbox malfunction
Back-up programme
When aut
om
atic

gearbox warning and indica-
tion lamps light up on the instrument panel,
there may be a system malfunction
››› page 142. In the event of some faults the
automatic gearbox functions using a backup
programme. When the programme is activa-
ted, it is possible to drive the vehicle, howev-
er, at low speeds and within a selected range
of gears.
With the manual gearbox, in some cases it is
not possible to drive with all the gears .
In all cases the automatic gearbox must be
checked at a specialised workshop. Automatic gearbox overheating
The automatic

gearbox can overheat with a
prolonged start up, or when stopping and
starting continuously. This overheating is dis-
played with a warning lamp  in the instru-
ment panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool
››› .
The v
ehic

le moves forward or back despite
having selected a gear range
When the vehicle does not move in the re-
quired direction, the system may not have
the gear range correctly engaged. Press the
brake pedal and engage the gear range
again. If the vehicle still does not move in the
required direction, there is a system malfunc-
tion. Seek specialist assistance and have the
system checked. CAUTION
● When the ge arbo

x is displayed as overheat-
ing for the first time, the vehicle must be
parked safely or must be driven at a speed of
more than 20 km/h (12 mph).
● When the warning lamp lights up and the
audible w
arning is heard, the vehicle must be
parked safely and the engine switched off.
Let the gearbox cool down.
● To prevent damage to the gearbox, driving
must
only be continued when the warning
lamps are no longer lit up. While the gearbox is overheated, starting up and driving, even
at a s
lo

w speed should be avoided. Recommended gear display

Operation
ahead as you drive and keep a safe distance
fr om the
v
ehicle in front, it is possible to slow
down by simply lifting your foot off the accel-
erator. This eliminates the need for constant
braking and acceleration.
Calm and steady driving
Constancy is more important than speed: The
more you drive at a constant speed, the lower
the fuel consumption.
When driving on the motorway, it is more effi-
cient to drive at a constant and more moder-
ate speed than to be continuously accelerat-
ing and braking. As a general rule, you will
reach your destination just as quickly when
you drive at a constant speed.
The cruise control function helps you to ach-
ieve a constant style of driving.
Moderate use of additional devices
It is important to travel in comfort, but con-
venience systems should be used ecological-
ly.
Some equipment, when connected, increase
fuel consumption considerably, for example:
● Air conditioning cooling system: If the air
conditioning sy
stem is required to cool to
significantly lower temperatures than the true
outside temperature, it will require a large
amount of energy from the engine. Therefore,
we recommend that the selected temperature for the vehicle is not too different to the out-
side temper

ature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with the windows
open. Then you can close the windows and
switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driv-
ing with the windows open increases fuel
consumption.
● Switch off the seat heating when the seats
have w
armed up.
● Switch off the heated rear window when it
is not
moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving
for the engine to warm up and to normalise
consumption.
The engine and catalytic converter need to
reach their proper working temperature in or-
der to minimise fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 150 shows the difference in consump-
tion for the same journey at +20°C (+68°F)
and at -10°C (+14°F).
Therefore, unnecessary short journeys
should be avoided. Try to combine trips. The vehicle uses more fuel in winter than in
summer, ev

en when other conditions are the
same.
The engine takes a long time to warm up
when it is idling. In addition, mechanical
wear and pollutant emissions are also espe-
cially high during this initial warm-up phase.
It is therefore best to drive off immediately af-
ter starting the engine. Doing this avoids run-
ning the engine at a high speed.
Adjusting type pressures.
Having the correct pressure in your tyres
helps to reduce rolling resistance and, as a
result reduces fuel consumption. Increasing
the tyre pressure slightly (+0.2
bar/+3 psi/+200 kPa) can help to save fuel.
When you buy new tyres, make sure they are
optimised for minimum rolling resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils,
known as low friction engine oil, helps to re-
duce fuel consumption. These oils reduce the
resistance caused by friction in the engine,
they flow around the engine more quickly
and efficiently, particularly in cold starts. The
effect is particularly noticeable in vehicles
frequently used for short journeys.
Always check the engine oil level and ob-
serve service intervals (engine oil change in-
tervals).

Operation
Catalytic converter The catalytic converter permits the subse-
quent tr
e
atment 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 189.
● Do not tow-start the vehicle; use the starter
cab l

es ›››
 page 43.
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
work in

g perfectly, there may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel
used. Driving tips
Driv in
g abr

oad In some countries, certain safety regulations
and requir
ements

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 f

or driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostic
s equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion countr
y?
● For petrol vehicles: Is unleaded petrol avail-
able at
the right octane rating?
● For diesel engines: is diesel fuel available
with a low s
ulphur content?
● Are a suitable engine oil ( ›››

page 189) and
other engine fluids complying with SEAT
specifications available in the destination
country?
● Are special tyres required in the destination
countr
y? CAUTION
SEAT does not accept liability for any damage
to the v

ehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving through flooded roadways
To prevent damage to the vehicle when driv-
ing thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded z

one. 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 sw it
c

h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water.
● Disconnect the Start-Stop system whenever
cro
ssing water. WARNING
When driving through water, mud, melted
sno w

, 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. 152

R emo
v

ing wax residue
Automatic car washes and certain car care
products may leave wax deposits on the win-
dows. These deposits can only be removed
with a special product or cleaning cloths. If
wax deposits are left on the windscreen and
the rear window, the blades can scratch the
glass. SEAT recommends you wipe the wax
deposits off the windscreen and the rear win-
dow with a soft cloth each time after you
have washed the vehicle.
A window cleaning detergent which helps to
dissolve the wax may be added to the wind-
screen washer fluid to prevent the wiper
blades from scratching the windscreen.
Please ensure you add the cleaning product
in the correct proportions. Products for re-
moving grease do not eliminate the wax de-
posits ››› .
S pec
i

al cleaning products or window cloths
are available at any technical service. To re-
move wax deposits, SEAT recommends the
following products:
● For the hottest time of the year: the window
cle
aner for summer use G 052 184 A1. Pro- portion 1:100 (1 part detergent, 100 parts
water) in the w

indscreen washer reservoir.
● All year round: the window clean-
er G 052 164 A2; proportion 1:2 in w
ind-
screen washer reservoir (1 part concentrate,
2 parts water) in winter, up to -18°C (-0.4°F),
or 1:4, during the rest of the year.
● Window cloths G 052 522 A1 for all win-
dows
and exterior mirrors.
Removing snow
Use a small brush to remove snow from the
windows and exterior mirrors.
Removing ice
If possible, use a de-icing spray to remove
ice. If you use an ice scraper, push it in one
direction only without swinging it. If you pull
the scraper backwards, the dirt may scratch
the window. WARNING
Dirty or misted windows reduce visibility in
al l

directions and increase the risk of acci-
dent and serious injury.
● Do not drive unless you have good visibility
through al
l windows!
● Remove ice and snow from the windows
and demist
inside and out. CAUTION
● Never mi x

our cleaning products with other
products not recommended by SEAT in the
windscreen washer reservoir. This could lead
to flocculation and may block the windscreen
washer jets.
● Do not use hot or warm water to remove ice
or snow fr
om the windows and exterior mir-
rors. The glass could crack!
● The heating element for the rear window is
located on the inner s
ide of the window. Do
not stick adhesive labels over the heating el-
ements and never clean the inside of the rear
window with corrosive or acid products or
other similar chemical cleaning products. Caring for and polishing the vehicle

The engine compartment should only be
cleaned by qualified personnel. If it is not
correctly cleaned, the anti-corrosion coating
and consequently electrical components may
be damaged. Moreover, water may filter di-
rectly into the vehicle interior through the wa-

shop for professional cleaning. SEAT recom-
mends taking your car in for technical serv-
ice.
Water box
The water box is in the engine compartment,
between the windscreen and the engine, and
beneath a perforated cover. Air is taken in
through the water box from outside to the ve-
hicle interior via the heating and air condi-
tioner.
Leaves and other loose objects should be
regularly cleaned away from the water box ei-
ther by hand or with a vacuum. WARNING
When working on the engine or in the engine
comp ar

tment, there is a risk of injury, burns,
accident or fire.
● Before starting work, please ensure you are
famili
ar with the required procedure and the
safety precautions ››› page 187.
● SEAT recommends getting a specialised
workshop t
o do these jobs. CAUTION
If water is manually poured into the water box
(e.g. u s

ing a high pressure cleaning appli-
ance), this could cause significant damage to
the vehicle. For the sake of the environment
Only wash the engine compartment in areas
al loc

ated for this purpose, to prevent dirty
water which may be contaminated by oil,
grease or fuel, from entering the drains. In
some places, even washing this compartment
outside planned areas for this purpose is
banned. 175

Advice
●
In those c ou
ntries where unleaded petrol is
not available, you may refuel with a fuel with
a low lead content. Natural gas
Natural gas can be compressed or in liquid
form, a
d

dition to others.
Liquefied natural gas (LNG) is the result of
heavy cooling of natural gas. Therefore its
volume is considerably reduced compared
with compressed natural gas (CNG). In vehi-
cles with a natural gas engine, liquefied nat-
ural gas cannot be directly refilled, as the gas
would expand excessively in the vehicle gas
tank.
Therefore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas ››› .
Nat ur
a

l gas quality and consumption
Natural gas is divided into the groups H and
L depending on its quality.
Gas type H has a superior heating power and
inferior nitrogen and carbon dioxide content
than type L. The higher the heating power of
the natural gas, the lower the consumption
will be.
However, the heating power and the propor-
tion of nitrogen and carbon dioxide can fluc-
tuate within the quality groups. Therefore, ve- hicle consumption can also vary when using
a singl

e type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need
for comprehensive draining before applying a
different quality gas.
Natural gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate
the v
ehic

le.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off
obj
ects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek

specialist assistance. Have the fault
repair
ed.
Regular checks of the natural gas system
The natural gas tanks may be damaged or
corroded by external factors. The walls of the
gas tanks are weakened by deformations,
damage or corrosion. As a result, the tanks
could burst and result in serious injuries or even death. For this reason, the vehicle own-
er must

have a specialised workshop check
(visual check) the gas system every 4 years
at least . The vehicle owner must have a spe-
cialised workshop replace the natural gas
tanks before they reach the end of their serv-
ice life. For further information about the
service life of gas tanks, go to a SEAT dealer
service or a specialised workshop WARNING
Failure to act when you can smell gas in the
vehic l

e or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. WARNING
The vehicle is not prepared to use liquefied
nat ur

al gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. WARNING
Damaged, corroded or rusted tanks can result
in serious injur

y or even death.
● Have the natural gas deposits checked at
lea
st every 4 years (visual check). 182

Checking and refilling levels
driving. Whenever the ignition is switched
on, the needl e c
h
anges first for a few sec-
onds to the petrol area in order to display the
current level of fuel. The needle then moves
to the natural gas area. After the engine is
started, the needle changes to the area corre-
sponding to the current operating mode.
Problem: if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af-
ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
su lt

in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply t
o the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack
of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the f
uel tank left to avoid running out of
fuel. CAUTION
● Alw a

ys pay attention to any lit control
lamps and to the corresponding descriptions
and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregu
lar fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

heating and keep them off during refuelling.
Refuelling
The correct petrol type for the vehicle is loca-
ted on a sticker inside the fuel tank flap
››› page 181.
● If the automatic filler nozzle is operated
correctly
, it will switch itself off as soon as
the fuel tank is full ››› .
● Do not continue to refuel if it is turned off!
Other w
i

se, this will fill the expansion cham-
ber and fuel may leak out if the ambient con-
ditions are warm.
Vehicles with a natural gas engine
Every 6 months it is necessary to run on pet-
rol until the control lamp switches off  and
then the tank must be refilled. This is neces-
sary to ensure the efficient operation of the
system and the fuel quality required for run-
ning on gas. WARNING
Do not continue refilling once the fuel nozzle
ha s

switched itself off. The fuel tank may be
filled too much. As a result, fuel may spurt
out and spill. This could lead to a fire, explo-
sion and severe injuries. » 185
