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. »

ssive steering can adapt steering hard-
ness to the current driving situation. The
power steering only works when the engine
is running.
In city traffic you do not need to turn so much
on parking, manoeuvring or in very tight
turns.
On the road or on the motorway, progressive
steering transmits, for example, in bends, a sportier, more direct and noticeably more dy-
namic driv

ing sensation.
Four-wheel drive 3 Valid for vehicles: with four-wheel drive


› ›

› table on page 2
On four-wheel drive models, the engine pow-
er is distributed to all four wheels
General notes
On four-wheel drive vehicles, the engine
power is distributed to all four wheels. The
distribution of power is controlled automati-
cally according to your driving style and the
road conditions. Also see ›››
page 176, Brak-
ing and stability systems .
The four-wheel drive is specially designed to
complement the superior engine power. This
combination gives the vehicle exceptional
handling and performance capabilities, both
on normal roads and in more difficult condi-
tions, such as snow and ice. Even so (or per-
haps especially for this reason), it is impor-
tant to observe certain safety points ››› .
W int
er ty

res
Thanks to four-wheel drive, your vehicle will
have plenty of traction in winter conditions,
even with the standard tyres. Nevertheless,
we still recommend that winter tyres or all- season tyres be fitted on all
four wheels t
o
give even better braking response.
Snow chains
On roads where snow chains are mandatory,
this also applies to cars with four-wheel drive
›››  page 60.
Changing tyres
On vehicles with four-wheel drive, all four
tyres must have the same rolling circumfer-
ence. Also avoid using tyres with varying
tread depths ››› page 273.
Off-roader?
Your SEAT is not an off-road vehicle: it does
not have enough ground clearance to be
used as such. It is therefore best to avoid
rough tracks and uneven terrain as much as
possible. WARNING
● Ev en w

ith four-wheel drive, you should al-
ways adjust your speed to suit the condi-
tions. Do not let the extra safety features
tempt you into taking any risks when driving.
Risk of accident!
● The braking capability of your vehicle is
limited by
the tyres' grip. It is therefore no
different from a car without four-wheel drive.
So do not be tempted to drive too fast on firm
or slippery roads just because the vehicle 254

n
leaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Super unleaded 98 octane or super 95 oc-
tane unleaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Petrol additives
The quality of the fuel 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 ››› .
S EA
T r

ecommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef

uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system. ●
Jus t

filling one full tank of leaded fuel or
fuel containing other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of

ation
s

(amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy ›››
page 255.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.

Wheel s
and ty

res
General notes –
When driving with new tyr e
s, be especially
careful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obs

tacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
dam ag

ed (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
plac

ed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
poss

ible.
– Mark the wheels before taking them off so
that they

rotate in the same direction when
put back.
– When removed, the wheels or tyres should
be stor

ed in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
away and should therefore be “run in” by driving carefully and at moderate speeds for
about the firs

t 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate that
one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.

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
