Driving
the Start-Stop system it is worth switching off
the en gine, f
or e
xample, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. Avoid running the engine at high
speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature in
order to minimise fuel consumption and
emissions. A cold engine consumes a disproportionate
amount of
fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 272 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. At speeds of 100-120
km/h (62-75 mph), this will save 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off any unneeded electrical devices. Devices that
use a lot of
electricity includes the blower at
a high setting, the rear window heating or
the seat heating*.

Introduction WARNING
● Bec au
se of the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the ar
ea of the exhaust system: Fire
hazard! Note
While the control lamps , , or re-
m ain lit, ther
e may be engine problems, fuel
consumption may increase and the engine
may lose power. 189

Towing bracket device
●
When operatin g the l
ever, do not apply too
much pressure (for example, do not stand on
it)! Note
Remove any dirt from the detachable ball be-
f or e
you put it away with the vehicle tools. Operation and care
Put the cover on the housing cavity so that
dir
t
c
annot get in.
Before hooking up a trailer, always check the
ball coupling and apply suitable grease if
necessary.
Use the protective cover when putting the de-
tachable ball away to keep the luggage com-
partment clean.
Remove any dirt from the housing cavity sur-
faces and use a suitable cleaning product. CAUTION
The top part of the hook housing is greased.
Mak e s
ure that the grease has not been re-
moved. Trailer towing
Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c
orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 243.
Connectors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re- duced by 10% for every further 1000 m (or
par
t
thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. »

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

Tyre useful life Fig. 243
Location of the tyre pressure sticker. Correct inflation pressures and sensible driv-
in
g h
ab
its will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to an
y long trip.
– The tyre pressure should only be checked
when the tyre
s are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the
vehicle. –
In vehic
les with a tyre pressure indicator,
save the modified pressure of tyres
››› page 275.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The usef
ul life of your tyres depends on the
following factors:
Tyre pressure
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap
››› Fig. 243.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (tyre pressure ). When driving
with comfort tyre pressure fuel consumption
may increase slightly.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap. Do not forget the spare wheel when checking
the tyre pr
essures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to
a pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Offi-
cial Service.

WARNING
● Alw a
ys adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the v
ehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicators
Fig. 244
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
w
orn. The origin
al
tyres on your vehicle have
1.6 mm high “trea
d wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.
The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.) WARNING
The tyres must be replaced at the latest when
the tre a
d is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
● Especially in difficult driving conditions
such a
s wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
● The scant driving safety due to insufficient
trea
d depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
● The speed has to be adapted accordingly,
otherwi
se there is a risk of losing control over
the vehicle. Changing wheels
Fig. 245
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheel
s
shou
ld be changed round from
time to time according to the system
››› Fig. 245. The useful life of all the tyres will
then be about the same time.
New tyres or new wheels –
All four wheels must be fitted with tyres of
the s ame type, s
iz
e (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not individual
ly (i.e. both front tyres or
both rear tyres together).
– Do not use tyres whose effective size ex-
ceeds
the dimensions of the factory-ap-
proved makes of tyre. »

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

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

The pressure in one or more tyres has
clearly reduced in comparison to the
tyre pressure set by the driver or the
tyre has structural damage.
Additionally, an audible warning can be heard and a text

damaged tyres. If flashing
System malfunction
The control lamp flashes for approximately one minute
and then lights up permanently.
If tyre pressure is correct, switch the ignition off and on
again. If the control lamp remains lit up, the tyre moni-
toring indicator can be calibrated. Have the system
checked by a specialised workshop.
Several warning and control lamps light up
f

switch off after a few seconds. WARNING
When the tyres are inflated at different pres-
sur e
s or at a pressure that is too low then a
tyre may be damaged resulting in a loss of control of the vehicle and a serious or fatal
acc
ident
.
● If the warning lamp lights up
, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sure
s or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pr
essure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all
of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label
››› page 283.
● The tyre monitoring system can only oper-
ate corr
ectly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can dam
age them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyre
s to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to mor
e flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyre
s can overheat and burst resulting in
a loss of vehicle control. ●
Ty r
e pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not hav
e to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING

Winter service Winter ty
res –
Winter tyres must be fitted on al
l
four
wheels.
– Only use winter tyres that are approved for
your v
ehicle.
– Please note that the maximum permissible
speed for w
inter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fective when the
tread is worn down. –
After fittin
g the wheels you must always
check the tyre pressures. When doing so,
take into account the correct tyre pressures
listed on the rear of the front left door
frame ››› page 272.
In winter road conditions winter tyres will
considerably improve vehicle handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. This applies particularly to vehi-
cles equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's docu-
ments (e.g. EC Certificate of Conformity or
COC 1)
). The vehicle documentation varies de-
pending on the country of residence. See al-
so ››› page 273.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
Winter tyres are subject to the following max-
imum speed limits according to speed rating
