Advice
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registration documents are no longer valid.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. 160

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

This only applies to vehicles with the fuel gauge on the dash panel display.
Several warning and indication lamps light
up for a few seconds when the ignition is
switched on, signalling that the function is
being verified. They will switch off after a few
seconds.
In natural gas engines
The warning lamp  lights up when both fuel
types (petrol and natural gas) have reached
reserve level.
The warning lamp  lights up when the vehi-
cle is running in natural gas operating mode.
The warning lamp  switches off when the
natural gas is exhausted. The engine
changes to operate with petrol.
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-
cl
e.
● Nev

er 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
The arrow next to the fuel pump symbol on
the ins trument

panel ››› Fig. 163 indicates the
side of the vehicle on which the fuel tank flap
is located. 182

Checking and refilling levels
WARNING
The engine compartment is a dangerous area
cap ab
le of causing serious injury.
● For all type of work, always take the utmost
precaution
s, work carefully and note the gen-
eral safety standards in force. Never take per-
sonal risks.
● Never work on the engine or in the engine
compar
tment if you are not familiar with the
necessary operations. If you are not sure
about procedures then visit a specialised
workshop to carry out the necessary work.
Working incorrectly can cause serious inju-
ries.
● Never open the bonnet if you see steam or
cool
ant escaping from the engine compart-
ment. This may cause serious burns. Always
wait until you cannot see or hear the sound of
steam or coolant coming from the engine
compartment.
● Always allow the engine to cool down be-
fore openin
g the bonnet.
● Contact with hot elements of the engine
and the exhau
st system can cause burns.
● Once the engine has cooled, follow the in-
structions
below before opening the bonnet:
– Engage the handbrake and place the gear
selector lever in N or the gear stick in
neutral.
– Remove the key from the ignition.
– Keep children away from the engine com-
partment and never leave them unsuper-
vised. ●
When the engine i s

warm or hot, the cool-
ing system is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
–After cooling, carefully and slowly un-
screw the cap anticlockwise, gently
pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth.
● When refilling liquids, avoid spilling them
on part
s of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. WARNING
The high voltages of the electrical system can
give el ectric

shocks as well as causing burns
and serious injury and possibly even death!
● Never cause short circuits in the electrical
syst
em. The battery could explode.
● To minimise the risk of electric shock and
serious c
onsequences while the engine is
running or starting the engine, note the fol-
lowing:
– Never touch the electrical wiring of the
ignition system. WARNING
In the engine compartment, there are rotat-
ing p ar

ts that could cause serious injury. ●
Never p l

ace your hands directly on or near
the radiator fan. Touching the rotor blades
could seriously harm you. The ventilator
works according to the engine temperature
and could start suddenly even when the igni-
tion is turned off and the key is removed.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from rotating parts, such as the drive
belts, alternator, radiator fan, etc., as well as
from the high-voltage ignition system. Al-
ways work with the utmost caution.
– Always make sure that no parts of your
body, jewellery, ties, loose clothing and
long hair can be trapped by the rotating
parts of the engine. Before any work, re-
move ties and jewellery (necklaces, etc),
tie long hair back and tie all items of
loose clothing to your body to make sure
that they cannot be trapped by engine
components.
– Take extreme caution when operating the
accelerator and remain attentive. The ve-
hicle could move, even if the handbrake
is applied.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths and tools, in
the engine compartment. If any object is left
in the engine compartment, this could cause
malfunctions, engine faults and even a fire. » 185

Checking and refilling levels
●
Never open the c oo
lant expansion tank if
steam or coolant is coming from the engine
compartment. Wait until you cannot see or
hear any steam or coolant escaping.
● Always wait until the engine has complete-
ly coo
led before very carefully opening the
expansion tank cap. Contact with hot ele-
ments of the engine can cause skin burns.
● When the engine is warm or hot, the cool-
ing sys
tem is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
– Carefully and slowly unscrew the cap an-
ti-clockwise, gently pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth.
● When refilling liquids, avoid spilling them
on part
s of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. Under
specific circumstances, the ethylene glycol
can catch fire. WARNING
If there is not enough anti-freeze in the cool-
ant sy s

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used. ●
When the outs ide t

emperature is very low,
the coolant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
● If ther e i

s no appropriate coolant liquid
available, fill it using distilled water, and
nothing else. Any other type of water may
lead to considerable rusting in the engine
due to its chemical components. This could
consequently damage the engine. If you have
not used distilled water but another type of
water to top up the coolant, a specialised
workshop must immediately replace all of the
fluid in the engine cooling system.
● Only top up coolant to the top level of the
marked ar
ea ››› Fig. 169. Otherwise the ex-
cess coolant will be forced out of the cooling
system when the engine is hot, causing dam-
age.
● If a lot of liquid coolant has been lost, wait
for the engine t
o cool down completely before
adding coolant. Extensive coolant loss is an
indication of leaks in the engine cooling sys-
tem. Have the engine cooling system inspec-
ted immediately by a specialised workshop.
Otherwise engine damage may occur.
● When refilling service liquids, ensure that
you put
the liquids into the right tank. Mak-
ing a mistake when refilling could cause seri-
ous malfunctions and damage the engine! CAUTION
The original additives should never be mixed
with c oo

lants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
● If the fluid in the expansion tank is not pur-
ple b
ut is, for example, brown, this indicates
that the G13 additive has been mixed with an
inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. Brake fluid

In the course of time, the brake fluid absorbs
water from the ambient air. If there is too
much water in the brake fluid, the brake sys-
tem could be damaged. In addition, the boil-
ing point of the brake fluid is significantly
lowered. When the brake fluid contains too
much water and the brakes are subject to
considerable forces, bubbles of water vapour
can form in the system. These bubbles can
significantly reduce braking power, notably
increasing braking distance, and could even
result in the total failure of the brake system. »
