Operation
ACC operation may be affected by a strong ra-
dar reverse reflection. This may occur, for ex-
ample, in a closed car park or due to the
presence of metallic objects (e.g. rails on the
road or sheets used in road works).
The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect ACC operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, ACC op-
eration may be affected. So structural modifi-
cations should only be made by specialised
workshops. SEAT recommends visiting a SEAT
dealership for this purpose.
If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and ACC operation may
be affected. So repair work should only be
made by specialised workshops. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. CAUTION
If you have the sensation that the radar sen-
sor is damaged or has lost its settings, dis-
connect the ACC. This will avoid possible
damage. If this occurs have it adjusted. ● The sensor may become damaged or lose
its settings when knocked, for example, dur- ing a parking manoeuvre. This may compro-
mise the system's efficacy or disconnect it.
●
Repairs to the radar sensor require special-
ist knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose.

Radar sensor Fig. 159
On the front bumper: radar sensor. A radar sensor is installed on the front bump-
er to determine the traffic situation
››› Fig. 159 1 . This sensor can detect vehi-
cles in front up to a distance of approximately
120 m.
The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
Front Assist monitoring system does not
work. The instrument panel displays the fol-
lowing message: Front Assist: No sensor vi- sion! If necessary clean the radar sensor ››› .
When the radar sensor begins to operate
properly again, the Front Assist will automati-
cally be available again. The message will
disappear from the instrument panel display.
Front Assist operation may be affected by a
strong radar reverse reflection. This may oc-
cur, for example, in a closed car park or due to the presence of metallic objects (e.g. rails
on the road or sheets used in road works).
The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect Front Assist operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, Front As-
sist operation may be affected. So structural
modifications should only be made by speci-
alised workshops. SEAT recommends visiting
a SEAT dealership for this purpose.
If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged

Accessories and modifications to the vehicle
Accessories, replacement parts and
repairs Always ask your dealer or specialist retailer
for advice before purchasing accessories and
replacement parts.
Your vehicle is designed to offer a high
standard of active and passive safety. For this
reason, we recommend that you ask a SEAT
Official Service for advice before fitting ac-
cessories or replacement parts. Your SEAT Of-
ficial Service has the latest information from
the manufacturer and can recommend acces-
sories and replacement parts which are suita-
ble for your requirements. They can also an-
swer any questions you might have regarding
official regulations.
We recommend you to use only
SEAT acces-
sories and
Genuine SEAT parts ®
. SEAT has
tested these parts and accessories for suita-
bility, reliability and safety. SEAT Official
Services have the necessary experience and
facilities to ensure that the parts are installed
correctly and professionally. Any
retro-fitted equipment which has a direct
effect on the vehicle and/or the way it is driv-
en, such as a cruise control system or elec-
tronically-controlled suspension, must be
approved for use in your vehicle and bear the
e mark (the European Union's authorisation
symbol).
If
any additional electrical devices are fitted
which do not serve to control the vehicle it-
self (for instance a refrigerator box, laptop or
ventilator fan, etc.), they must bear the
sign (manufacturer conformity declaration in
the European Union). WARNING
Accessories, for example telephone holders
or cup holders, should never be fitted on the
covers, or within the working range of the air-
bags. Otherwise, there is a danger of injury if
the airbag is triggered in an accident. Technical modifications
Modifications must always be carried out ac-
cording to our specifications.
Unauthorised modifications to the electronic
components, software, wiring or data transfer
in the vehicle may cause malfunctioning. Due
to the way the electronic components are
linked together in networks, other indirect
systems may be affected by the faults. This
can seriously impair safety, lead to excessivewear of components, and also invalidate your
vehicle registration documents.
You will appreciate that your SEAT dealership
cannot be held liable for any damage caused
by modifications and/or work performed in-
correctly.
We therefore recommend that all work should
be performed by a SEAT Official Service using
genuine SEAT parts

. WARNING
Incorrectly performed modifications or other
work on your vehicle can lead to malfunctions
and cause accidents. Two-way radios and office equipment
Radio transmitters (fixed installation)
Any retrofit installations of radio transmitters
in the vehicle require prior approval. SEAT
generally authorises in-vehicle installations
of approved types of radio transmitters provi-
ded that:
●
The aerial is installed correctly.
● The aerial is installed on the exterior of the
vehicle (and shielded cables are used togeth-
er with non-reflective aerial trimming).
● The effective transmitting power does not
exceed 10 Watts at the aerial base.

Wheels
Depending on the vehicle, tyre pressure can
be adjusted (“comfort” tyre pressure) to in-
crease driving comfort. 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 pressures: 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 wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If you notice excessive tyre wear, you should
check wheel alignment at a SEAT Official
Service.
WARNING
● Always adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the vehicle 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. 177
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
worn.
The original tyres on your vehicle have
1.6 mm high “tread 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.)

it means, for example, that the tyre was man-
ufactured in the 22nd week of 2012.
But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the tyres rub against the bodywork, in certain
circumstances the tyres , suspension or
bodywork and pipes may be damaged, and
vehicle safety could be severely impaired
››› .
If you use tyres that are approved by SEAT
you can be sure that the actual tyre dimen-
sions will be correct for your vehicle. If you
decide to fit a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.
Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.
It is best to have all servicing of wheels and
tyres performed by a specialised workshop.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres respecting the envi-
ronment. WARNING
● It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads.
●
Avoid running the vehicle on tyres that are
more than 6 years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● If wheel trims are fitted after the car is pur-
chased, 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 laws in the country concerned. Note
● Never mount used tyres if you are not sure
of their “previous history”.
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts

When installing different wheels (for instance
