Safety General information
Assorted assistance systems – which vary
depending on the equipment
fitt

ed in the car
– will help you when parking or manoeu-
vring.
The rear parking aid is an audible assistant
that warns about obstacles located behind
the vehicle ››› page 238.
During parking, Parking System Plus assists
the driver by visually and audibly warning
them about obstacles detected in front and
behind the vehicle ››› page 239. WARNING
● Alw a

ys pay attention, also when looking
straight ahead, to traffic and the vehicle sur-
roundings. The assistance systems are not a
replacement for driver awareness. When in-
serting or removing the vehicle from a park-
ing space, or when performing similar ma-
noeuvres the driver always assumes the re-
sponsibility.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions.
● The ultrasound sensors have blind spots in
which ob
stacles and people are not regis-
tered. Pay special attention to children and
animals.
● Always keep visual control of the vehicle
surrou
ndings: use the mirrors for additional
help. CAUTION
Parking Aid functions may be negatively af-
fect ed b

y different factors that may lead to
damage to the vehicle or its immediate sur-
rounds:
● Under certain circumstances, the system
does not
detect or display certain objects:
– Objects such as chains, trailer draw bars,
fences, posts and thin trees.
– Objects that are located above the sen-
sors, such as protrusions in a wall.
– Objects with certain surfaces or struc-
tures, such as wire mesh fences or pow-
der snow.
● Certain surfaces of objects and garments
do not refl
ect the ultrasound sensors' sig-
nals. The system cannot detect, at least cor-
rectly, these objects or people wearing such
clothes.
● Ultrasound sensor signals may be affected
by e
xternal sound sources. In certain circum-
stances this may prevent them from detect-
ing people or objects.
● Please note that low obstacles detected by
the syst
em may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. In
certain circumstances, objects such as high
kerbs that could damage the bottom of the
vehicle are not detected either.
● If the first warning from the ParkPilot is ig-
nored, the v
ehicle could suffer considerable
damage. » 237

Care and maintenance
A SEAT Official Service and specialised work-
shop w i
l
l be able to inform you about options
for installing and operating radio transmitters
with a higher transmitting power.
Mobile radio transmitters
Commercial mobile telephones or radio
equipment might interfere with the electron-
ics of your vehicle and cause malfunctions.
This may be due to:
● No external aerial.
● External aerial incorrectly installed.
● Transmitting power more than 10 W.
You mus
t, therefore, do not operate portable
mobile telephones or radio equipment inside
the vehicle without a properly installed exter-
nal aerial ››› .
Pl e
a

se note also that the maximum range of
the equipment can only be achieved with an
external aerial.
Business equipment
Retrofit installation of business or private
equipment in the vehicle is permitted, provi-
ded the equipment cannot interfere with the
driver's immediate control of the vehicle and
that any such equipment carries the  mark.
Any retrofit equipment that could influence
the driver's control of the vehicle must have a
type approval for your vehicle and must carry
the e mark. WARNING
Mobile telephones or radio equipment which
is oper

ated inside the vehicle without a prop-
erly installed external aerial can create exces-
sive magnetic fields that could cause a health
hazard. Note
● The pos t

erior fitting of electric and elec-
tronic equipment in this vehicle affects its li-
cence and could lead to the withdrawal of the
vehicle registration document under certain
circumstances.
● Please use the mobile telephone/radio op-
erating in
structions. Care and cleaning
Gener a

the
value of the vehicle. This may also be one
of the requirements for upholding any war-
ranty claims in the event of corrosion or paint
defects.
SEAT Official Services and specialist retailers
carry stocks of suitable car care materials.
Please follow the instructions for use on the
packaging. WARNING
● Cle

aning products and other materials used
for car care can be damaging to your health if
misused.
● Always keep care products in a safe place,
out of the r
each of children. Failure to comply
could result in poisoning. For the sake of the environment
● If po s

sible, use environmentally friendly
products.
● The remains of car care products should not

se, oil, lipstick or ball point pen. Then
dab the dissolved grease or colour particles
off with an absorbent cloth or similar. You
may also have to treat the stain once more
using washing paste and water.
If the covers or textile trim panels are badly
soiled we recommend that you have them
cleaned by a professional cleaning company
with a shampoo and spray. Note
Open Velcro fasteners on clothes can damage

lstery. Make sure they are
closed. Natural leather
General information
Our r
an
g

e of leathers is large. The main type
used is particularly nappa in various forms,
that is, leather with a smooth surface in dif-
ferent colours.
The amount of dye used determines the ap-
pearance and properties of leather. If the
leather is left in a more natural state, it re-
tains its typical natural napped appearance
and confers excellent all-weather properties
to the seats. Fine veins, healed scars, insect
bites, wrinkles and a subtle variation in shad- ing remain visible; these are the characteris-
tic fe

atures of genuine natural leather.
Natural napped leather does not have a pro-
tective surface coating of dye. It is therefore
somewhat more prone to damage. This
should be borne in mind if children or pets
often travel in the car, or if there are other
factors that could lead to damage.
Types of leather with a coloured surface coat-
ing are likely to be more resistant to damage.
This has a great advantage for day-to-day
use. However, this means that the typical
natural characteristics of the surface are less
apparent, though this does not affect quality.
Cleaning and care
Due to the natural properties of the specially
selected hides employed, the finished leath-
er has a certain sensitivity to grease and dirt,
etc. so a degree of care is required in every-
day use and when looking after the leather.
Dark clothing (especially if damp or incorrect-
ly dyed) may stain leather upholstery on the
seats. Dust and grit in the pores and seams
can scratch and damage the surface. There-
fore leather should be cleaned at regular in-
tervals, depending on the actual amount of
use. When they have been in use for a certain
time, your car seats will acquire a typical and
unmistakable patina. This is characteristic for
leather as a natural product and is a sign of
genuine quality. To maintain the value of natural leather you
should not
e the following points: CAUTION
● Av oid e

xposing leather to direct sunlight
for long periods, otherwise it may tend to
lose some of its colour. If the car is left for a
prolonged period in the bright sun, it is best
to cover the leather.
● Sharp-edged objects on clothing, such as
belts, z
ip fasteners, rivets or similar, can also
leave permanent scratches and rough marks
on the surface of the leather. Note
● Use a s uit

able impregnating cream with ul-
tra-violet protection at regular intervals and
after cleaning. The cream nourishes and
moisturises the leather, keeps it supple and
able to breathe. A protective film will also
form.
● Clean the leather every 2 to 3 months and
remov
e fresh dirt as soon as possible.
● Remove stains from fresh ball-pen and oth-
er inks, lips
tick, shoe cream and similar
stains as soon as possible.
● Preserve the colour of the leather. A special
colour
ed cream will renew the colour of the
leather when required and will eliminate dif-
ferences in colour. 262

Checking and refilling levels
could d amage the engine. If there is no
c oo
lant in the expansion tank, do not con-
tinue driving. You should obtain professio-
nal assistance ››› .
– If there is still some coolant in the expan-
sion t
ank, t

op up to the upper mark.
– Top up with coolant until the level becomes
stab

le.
– Screw the cap back on correctly.
Any lo
ss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coo lin

g system is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health h
azard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● If working inside the engine compartment,
remember that, ev
en when the ignition is
switched off, the radiator fan may start up au- tomatically, and therefore there is a risk of in-
jury
. WARNING
If there is not enough anti-freeze in the cool-
ant sys

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 outside temperature is very low,
the cool
ant 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
Do not top up the expansion tank with cool-
ant fluid if it

is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. 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
ina
dequat

e coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
en vir

onment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Brake fluid

Changing brake fluid
The regular intervals at which the brake fluid
should be replaced are listed in the Mainte-
nance Programme. We recommend you have
it replaced at a SEAT Official Service, during
an Inspection Service. WARNING
● Brak e fluid shou

ld be stored in the closed
original container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the br
akes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid should not come into contact with
the v ehic
