In the windscreen: field of vision of
the Lane Assist system camera. Using the camera located in the windscreen,
the Lane Assist system detects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with
a
corrective steering movement
.
Thi s move-
ment can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.
Steering wheel vibration
The following situations cause vibration in
the steering wheel and require the driver to
take active control of driving:
● When the limits of the very nature of the
system are reached. ●
When the maximum rotational torque dur-
ing the corrective steering movement is not
enough to keep the vehicle inside the lane.
● When no lane is detected during the correc-
tive steering movement.

Advice
Engine oil General notes The engine comes with a special, multi-grade
oil that can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the
›››
page 201, Oil properties .
Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6,
this means that your vehicle has the LongLife service programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it
must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
tervals.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 201 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals › ››
page 201 (up to a maximum of 0.5 li-
tres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals
, which also appear in ››› page 201,
Oil properties . In this case, your vehicle must
be serviced after a fixed interval of 1
year/15,000 km (10,000 miles)(whatever comes first)
››› Booklet Maintenance Pro-
gramme.
● In ex

ceptional circumstances, if the engine
oil level is too low ››› page 201 and you can-
not o

btain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 201 and
you cannot obtain the oil specified for your
vehicle, you can use a small quantity of oil
(once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or
ACEA B3/ACEA B4 specification. (up to 0.5 l).

Advice
Wheels
Wheels and tyres General notes –
When driving with new tyres, be especially
car
eful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obstacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
damaged (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
placed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
possible.
– 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 stored in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
a w

ay and should therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may
v
ary, 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. Useful life of tyres Correct inflation pressures and sensible driv-
ing habits will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to any long trip.
– The tyre pressure should only be checked
when the tyres are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the vehicle.
– In vehicles with a tyre pressure indicator,
save the pressure of modified tyres
››› page 212 , ››
›
page 208.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The useful 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.
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.

Advice
WARNING
The tyres must be replaced at the latest when
the tread 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 as 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
tread 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,
otherwise there is a risk of losing control over
the vehicle. Changing wheels
Fig. 178
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
››› Fig. 178 . The useful life of all the tyres will
then be about the s
ame time.
Replacing wheels and tyres –
All four wheels must be fitted with tyres of
the same type, size (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not individually (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.
– If you wish to fit the vehicle with rims or
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of-
ficial Service before purchasing them.
The ty r

es and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
and safe handling ››› .
The sizes of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document 1)
). The vehicle documentation
varies depending on the country of resi-
dence.
Note for Italy: A SEAT Service Centre should
be c on

sulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre: 1)
COC = certificate of conformity.

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
may lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are maintained 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 tyres are cold at all times
››› page 243.
● Re
gularly check the cold inflation pressure
of the tyres. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold.
● Regularly check your tyres for damage and
wear. ●
Never exceed the maximum permitted
speed or loads specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
consumption and tyre wear. Note
● Driving for 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. Regularly 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. Tyre monitor indicator warning lamp

control of the vehicle and a serious or fatal
accident.
●
If the warning lamp  lights up, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sures 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 pressure 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 243.
● The ty r
e monitoring system can only oper-
ate correctly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can damage 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
tyres to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to more 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 tyres can overheat and burst resulting in
a loss of vehicle control. ●
Tyre 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 have 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
Observe the safety warnings ››› in Control
and warning lamps on page 71. Note
● If excessively low tyre pressure is detected
with the ignition on, an audible warning will
sound. In the event that there is a fault in the
system, an audible warning will sound.
● Driving on dirt tracks for a long period of
time or driving in a sporty style can tempora-
rily deactivate the TPMS. The control lamp
shows a fault, but disappears when road con-
ditions or the driving style change. Tyre monitoring indicator

Note
In practice, and considering all the factors
mentioned here, consumption values can dif-
fer from those calculated in the current Euro-
pean regulations. Weights
Kerb weight refers to the basic model with a
fuel tank filled to 90% capacity and without
optional extras. The figure quoted includes
75 kg to allow for the weight of the driver.
Special versions, optional equipment fittings
or retro-fitting accessories will increase the
weight of the vehicle

WARNING
● Please note that the centre of gravity may
shift when transporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Always adjust your speed and driving
style to suit road conditions and require-
ments.
● Never exceed the gross axle weight rating
or the gross vehicle weight rating. If the per-
missible axle load or the permissible total
weight is exceeded, the driving characteris-
tics of the vehicle may change, which could
lead to accidents, injuries and damage to the
vehicle. Towing a trailer
Trailer weights Trailer weight
The trailer weights and drawbar loads ap-
proved are selected in intensive trials accord-
ing to precisely defined criteria. The ap-
proved trailer weights apply to vehicles in the
EU and generally for maximum speeds of 80
km/h (100 km/h in c
er
tain circumstances).
The figures may be different in other coun-
tries. All data in the official vehicle documen-
tation takes precedence over these data at all
times ››› .
Drawbar loads
The maximum
permitted drawbar load on the
b

all joint of the towing bracket must not ex-
ceed
80 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er on the road will be poor, if the drawbar
load is too small.
If the maximum permissible drawbar load
cannot be met (e.g. with small, empty and
light-weight single axle trailers or tandem
axle trailers with a wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load. WARNING
● For safety reasons, do not exceed the 80
km/h (50 mph) limit. This is also valid in
countries where higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawbar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels
