The essentials
Multifunction display (MFI) The multifunction display (MFI) has two auto-
matic
memorie
s: 1 - Partial memory and 2 -
Total memory . The selected memory will be
shown in the lower right-hand corner of the
display.
With the ignition switched on, and memory 1 or
2 displayed, briefly press OK to change from
one memory to another.
1
Trip memo-
ry (for a
single jour-
ney).
The memory stores the values for the
journey and the consumption from
the moment the ignition is switched
on until it is switched off again.
If the journey is broken for more than
2 hours, the memory is automatically
erased. If the journey is continued in
less than 2 hours after the ignition is
switched off, the new data is added to
the data already stored in the memo-
ry.
2Total mem-
ory (for all
journeys).
The memory stores the values of any
number of journeys, until it counts a
total of 19 hours and 59 minutes of
driving, or 1999.9 km or miles of driv-
ing, depending on the type of instru-
ment panel fitted. On reaching either
of these limits, the memory is auto-
matically erased and starts to count
from 0 again. Possible displays

Operation
for the vehicle is not too different to the out-
s ide t
emper
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. 147 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). When purchasing engine oil, always observe
leg
al requirements and ensure that the oil is
approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical
and ecological the driving style. For example,
an additional weight of 100 kg will increase
fuel consumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads
from the vehicle.
Remove optional equipment and unnecessa-
ry accessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and racks,
especially if you intend to drive at high
speeds.
Other factors which increase fuel consump-
tion (examples):
● Fault in engine management.
● Driving on hills.

Care and maintenance
also be one of the requirements for acknowl-
edgin g w
arr
anty claims in the event of body-
work corrosion or paint defects.
Products suitable for the care of your vehicle
are available at any technical service. WARNING
Car-care products may be toxic and hazard-
ous. If c

ar care products are not suitable or
are used inappropriately, this could result in
accident, serious injury, burns or intoxica-
tion.
● Car care products must always be stored in
the original
container which should be kept
closed.
● Observe information provided by the manu-
factur
er.
● To prevent confusion, never store car care
products
in empty food cans, bottles or other
containers.
● Keep all care products out of reach of chil-
dren.
● Harmfu

l vapours may be produced when us-
ing car c
are products. Therefore, care prod-
ucts should only be used in well-ventilated
spaces or in the open air.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid to wash,
clean or care for the vehicle. These are toxic
and highly flammable. WARNING
Inappropriate care and cleaning of vehicle
component s

may effect the vehicle safety
equipment, increasing the risk of severe in-
jury.
● Vehicle components should only be
cle
aned and maintained in accordance with
the manufacturer's instructions.
● Only use approved or recommended care
products. CAUTION
Cleaning products which contain solvents will
dam ag

e the material. For the sake of the environment
Only wash the vehicle in areas allocated for
this p

urpose, to prevent dirty water which
may be contaminated by oil, grease or fuel,
from entering the drains. In some places,
even washing it outside the planned areas is
banned. For the sake of the environment
Where possible, always use products which
re s

pect the environment. For the sake of the environment
The remains of car care products should not
be dis po

sed of with ordinary household waste. Observe information provided by the
manuf
act

urer. Washing the vehicle
The longer substances such as insects, bird
drop
pin

gs, resinous tree sap, road dirt, in-
dustrial deposits, tar, soot or road salt and
other aggressive materials remain on the ve-
hicle, the more damage they do to the paint-
work. High temperatures (for instance due to
strong sunlight) further intensify the corro-
sive effect. The vehicle undercarriage should
also be thoroughly washed at regular inter-
vals.
Automatic car washes
Always observe the instructions provided at
the automatic car wash. The standard pre-
cautionary measures prior to entering the car
wash should be taken to avoid damage to
the vehicle (close all windows, fold in exterior
mirrors). If the vehicle is fitted with additional
components (spoiler, roof-rack, aerial, etc.),
check with the car wash supervisor whether
these can enter the car wash ››› .
The v
ehic

le paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, wear and damage to the paintwork
will depend on the type of car wash used. »

Using your vehicle in other countries
and continents The vehicle is manufactured at the factory for
u
se in a p
ar

ticular country in accordance with
the national legislation in force at the time of
manufacture.
If the vehicle is sold in another country or
used in another country for an extended peri-
od of time, the applicable legislation of that
country should be observed. It may be necessary to fit or remove certain
pieces

of equipment or to deactivate certain
functions. Service work may also be affected.
This is particularly true if the vehicle is used
in a different climate for an extended period
of time.
As there are different types of frequency
bands around the world, you may find that
the radio system or the Portable Navigation
System (supplied by SEAT) supplied at the
factory does not work in another country. CAUTION
● SEA T doe

s not accept liability for any dam-
age to the vehicle due to the use of a lower
quality fuel, an inadequate service or the
non-availability of genuine spare parts.

P etr
o

l types are categorised according to
their octane number (e.g. 91, 95, 98 or 99
RON (RON = “Research Octane Number”).
You may use petrol with a high octane num-
ber than the one recommended for your en-
gine. However, this has no advantage in
terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sul-
phur content or sulphur-free petrol to reduce
fuel consumption for petrol engines. Petrol additives
The quality of the f

uel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al
l

petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .

metal additives. Using them may damage the
engine!
● On ly
use fuel with an octane rating that is
in line with the norm EN 228, otherw
ise sig-
nificant damage could be caused to the en-
gine and fuel system. Furthermore, it could
lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could
seriously
damage the engine and the catalyt-
ic converter.
● If, in exceptional circumstances, petrol with
a lower oct
ane rating to that recommended is
used, only use moderate engine speeds and a
light throttle. Avoid using full throttle and
overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suita-
ble octane rating as soon as possible.
● Just filling one full tank of leaded fuel or
with other meta
l additives would seriously
impair the efficiency of the catalytic convert-
er and could damage it. Natural gas
Natural gas, in addition to others, can be in
li
quid f
orm.
Li

quefied 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.
Theref

ore, 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
one 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. ●
Sw it
c

h the ignition off.
● Open the doors to appropriately ventilate
the vehic
le.
● Immediately extinguish cigarettes.
● 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. 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. Note
The natural gas system must be subject to
re gu

lar inspections at a specialised work-
shop in accordance with the Maintenance
Programme. 179

Refuelling or handling fuel carelessly can
cau se an e

xplosion or fire resulting in serious
burns and injuries.
● Always make sure that you correctly close
the fuel c
ap to avoid evaporation and fuel
spillage.
● Fuels are highly explosive and inflammable
subs
tances that can cause serious burns and
injuries.
● Fuel could leak out or be spilt if the engine
is not
switched off or if the filler fuel nozzle is
not fully inserted into the tank filler neck
when refuelling. This could lead to a fire, ex-
plosion and severe injuries.
● When refuelling, turn off the engine and
turn off the ignition f
or safety reasons.
● Always turn off mobile telephones, radio
appar
atus and other radio wave emitting
equipment before refuelling. Electromagnetic
waves could cause sparks and lead to a fire.
● Never enter the vehicle while refuelling. If it
is ab
solutely necessary to enter, close the
door and touch a metal surface before touch- ing the filler nozzle again. This will prevent
the gener
ation of

static electricity. Sparks
could cause a fire when refuelling.
● Never handle fuel close to flames, sparks or
obj
ects with slow combustion (e.g. ciga-
rettes).
● Avoid static electricity and electro-magnet-
ic ra
diation when refuelling.
● Observe the safety regulations of the serv-
ice st
ation.
● Never spill fuel on the vehicle or in the lug-
gage c
ompartment. WARNING
For safety reasons, SEAT does not recommend
carr y

ing a spare fuel canister in the vehicle.
Fuel could be spilled and catch fire, above all
in case of an accident and this applies to a
full container as well as empty containers.
This could lead to explosions, fires and inju-
ries.
● Observe the following if you exceptionally
have t
o carry fuel in a canister:
– Never place a fuel container, to fill it, in-
side the vehicle or on the vehicle, for ex-
ample, in the luggage compartment. Fill-
ing in these circumstances could create
an electrostatic charge and spark that
could ignite fuel fumes.
– Always place the canister on the ground
to fill it. –
Inser t

the fuel nozzle into the neck of the
canister as far as possible.
– If you are using a metal fuel canister, the
nozzle must always touch the canister
while it is being filled to avoid static elec-
tricity.
– Follow the legal requirements for the use,
storage and transport of spare fuel canis- ters.
– Insure that the fuel container complies
with manufacturing standards, for exam-
ple, ANSI or ASTM F852-86. CAUTION
● Alw a

ys remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can
cause seriou
s engine and fuel system dam-
age; the resulting malfunctions are not cov-
ered by the SEAT warranty. If you refuel with
the wrong type of fuel, never start the engine.
This applies to even the smallest amount of
the wrong fuel. Seek specialist assistance.
With the engine running, the composition of
the wrong fuel could significantly damage the
fuel system and the engine itself. For the sake of the environment
Fuels can contaminate the environment. Col-
