eight distribution
The weight distribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum 1)
This does not apply for vehicles with bi-xenon

ather or w
ind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 109.

Care and maintenance
Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions such as closing
the windows and roof. If the vehicle has spe-
cial accessories such as spoilers or a roof
rack or two-way radio aerial, etc., it is advisa-
ble to consult the car wash tunnel operator.
It is best to use a car wash without revolving
bristles if possible.
Washing the vehicle with a high pressure
cleaner
When washing the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. This applies
particularly to the operating pressure and the
spraying distance. Do not hold the nozzle too
close to soft materials such as rubber hoses
or seals. The same applies to the parking aid
sensors*, which are located in the rear bump-
er.
Do not use a nozzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt.
Stickers attached by the factory
Follow these directions to avoid damaging
the stickers:
● Do not use high pressure cleaners.
● To remove ice or snow from the stickers do
not use w
indow scrapers or ice scrapers. ●
Do not poli
sh the stickers.
● Do not use dirty cloths or sponges.
● Preferably wash using a soft sponge and
soft neutr
al soap.
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
You should start on the roof and work down.
Special car soap should only be used for very
persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
● The v ehic

le should only be washed with the
ignition switched off. Failure to follow this in-
struction could result in an accident.
● Do not clean the underside of chassis, the
inside of
wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Other-
wise, there is a risk of sustaining cuts.
● When washing the car during the winter
season: w
ater and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not w a

sh the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
spong
es or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlight
s at regular intervals, for in-
stance when filling the fuel tank. The head-
lights should only be washed with water, do
not wipe them with a dry cloth or sponge. It
is best to use soapy water.
● Never wash tyres with a jet that sprays the
water out
in a direct stream. This could dam-
age the tyres even if the spray is kept at a
distance and only used for a very short time.
● Before washing the vehicle in an automatic
car wa
sh, please make sure to retract the ex-
terior mirrors to prevent them from being
damaged. Electrically retractable exterior
mirrors must not be folded in or out by hand,
always use the electrical power control. CAUTION
● Bef or

e washing the vehicle in an automatic
car wash, please proceed as follows to lock
the wiper arms so that they are not moved to-
wards the top of the windscreen:
–the bonnet must be closed.
– switch the ignition on and off.
– press the windscreen wiper lever forward
briefly (windscreen washer function).
This will lock the wiper arms. » 247

Please note when cleaning the wheels that
wat er
, ice and road salt can impair the effec-
tiveness of the brakes; this can cause an acci-
dent. Exhaust tail pipe
It is important to remove road salt and brake
dus
t

by washing the wheels at regular inter-
vals, otherwise the exhaust tail pipe material
could be damaged. To remove impurities, do
not use rim, paint or chrome cleaners or oth-
er abrasive products. Clean the exhaust tail
pipes with cleaning products that are suita-
ble for stainless steel.
SEAT Official Services carry stocks of cleaning
products that have been tested and ap-
proved for use on your vehicle.

ssionally available “LCD cleaner”.
Moisten the cloth with a small amount of the
cleaning fluid. The Easy Connect control panel* should first
be cle

aned with a brush so that no dirt goes
into the device or between the keys and
housing. Next, we recommend cleaning the
Easy Connect control panel* using a cloth
dampened with water and washing-up liquid. CAUTION
● To av oid s

plastic parts and leatherette should only be
treated with a special solvent-free plastic
cleaner.

leaned regularly with a vac-
uum cleaner. This will remove surface dirt
which could otherwise be rubbed into the
textile material during use. Do not use steam
cleaners, as the steam could carry the dirt
deeper into the textile material. Normal cleaning
We rec

ommend that you use a soft sponge or
a commercially available lint-free, micro-fibre
cloth for normal cleaning. Only use brushes
on floor coverings and mats, as other textile
surfaces could become damaged.
In the case of normal surface dirt you can use
a foam cleaner. Use a sponge to spread the
foam on the textile surface and to work it into
the material lightly. However, make sure that
the textile material does not become soaking
wet. Then dab off the foam with a dry and ab-
sorbent cloth (e.g. a micro-fibre cloth) and
vacuum off any residue once the surface is
completely dry.
Cleaning stains
Treat drink stains (such as coffee or fruit
juice, etc.) with a cleaning solution for deli-
cate fabrics. This solution should be applied
with a sponge. If the stains are difficult to re-
move, a washing paste can be applied direct-
ly onto the stain and worked into the fabric.
The surface will then have to be wiped with
clear water to remove any residue left by the
paste. To do so, use a damp cloth or sponge
and then dab the stain with an absorbent
cloth.
Remove chocolate or make-up stains with a
cleaning paste (for e.g., soft soap). Then re-
move the soap with water (wet sponge).

Checking and refilling levels
●
Tak e c
are not to cause short circuits in the
electrical system, especially when working
on the battery.
● 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.
● Never cover the engine with additional in-
sul
ating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap with a l
arge, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
partment
while the engine is running, the ro-
tating components (for example, poly-V belt,
alternator, radiator fan) and the high voltage
ignition system are an additional hazard.
● Observe the following additional warnings
if work
on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid is p

ut into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage. For the sake of the environment
Inspect the ground underneath your vehicle
re gu

larly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop. Note
In right-hand drive vehicles* some brake flu-
id re ser

The bonnet is released from inside the vehi-
cle.
Check that the windscreen wiper arms are
not unfolded. Otherwise the paint may be
damaged.
The bonnet can only be unlocked when the
driver door is open. WARNING
Never open the bonnet if you see steam or
drips of

coolant being released from the en-
gine compartment. Failure to comply could
result in burns. Wait until no steam or coolant
can be seen before opening the bonnet. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay before pressing it
bac k

into its support.
– Carefully close the bonnet.
– Press the bonnet down until it locks into
plac

e.
– Make sure that the bonnet catches onto its
cla

sp. Do not press down too hard ››› .
WARNING
● For s af

ety reasons the bonnet must always
be completely closed when the vehicle is
moving. Therefore, after closing the bonnet,
always check that the locking element is
properly engaged. This is the case if the bon-
net is flush with the adjacent body panels.
● Should you notice that the bonnet is not
safely
secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet. Failure to follow this instruction
could result in an accident. 263

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

acity
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer. WARNING
If the water from the windscreen washer does
not c ont

ain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contain
s enough anti-freeze.
● In cold conditions, you should not use the
winds
creen wiper system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
simi l

ar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.
● Use clean water with a window cleaner rec-
ommended by
SEAT.
● If necessary, add a suitable antifreeze to
the water in the r
eservoir.268

Wheels
●
Av oid ru
nning the vehicle on tyres that are
more than 6 years old. If you have no
alternative, you should drive slowly and with
extra care at all times.
● If wheel trims are fitted after the car is pur-
cha
sed, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the l aw

s in the country concerned. Note
● A S EA

T Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● Never mount used tyres if you are not sure
of their “pr
evious history”.
● For technical reasons, it is not generally
poss
ible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts
The wheel
bolts
ar
e m
atched to the rims.
When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and correctly shaped bolt
head

s. This ensures that wheels are fitted se-
curely and that the brake system functions
correctly.
The wheel bolts must be clean and turn easi-
ly.
A special adapter is required to turn the anti-
theft wheel bolts* ›››

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
ma y

lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are m
aintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label when the ty
res are cold at all times
››› page 283.
● Regularly check the cold inflation pressure
of the tyr
es. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re gu

larly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
c on s

umption and tyre wear. Note
● Driv ing f

or the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised by
SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Re
gularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. 275
