Operation
in braking, such as in work areas or if there
are metal rails.
●
If the operation of the City Emergency brak-
ing function is impaired, for example, by dirt
or because the radar sensor has lost its set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.
● During driving, the City Emergency braking
function does not react to people or animals
or vehicles crossing your path or which ap-
proach you head-on in the same lane. Note
● When the City Emergency braking function
causes a braking, the brake pedal is “hard-
er”.
● Automatic interventions on the brakes by
the City Emergency braking function may be
interrupted by pressing the clutch, accelera-
tor or moving the wheel.
● The City Emergency braking function can
brake the vehicle until it stops completely.
However, the brake system does not halt the
vehicle permanently. Use the foot brake!
● If several inopportune intervenes occur,
switch off the Front Assist and with it the City
Emergency braking function. Take it to a spe-
cialised workshop, SEAT recommends visiting
a SEAT dealership.
● If numerous unnecessary interventions oc-
cur, the City Emergency braking function may
switch off automatically. Lane Assist system*
Introduction WARNING
The intelligent technology in the Lane Assist
system cannot change the limits imposed by
the laws of physics and by the very nature of
the system. Careless or uncontrolled use of
the Lane Assist system may cause accidents
and injury. The system is not a replacement
for driver awareness.
● Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● Always keep your hands on the steering
wheel so it can be turned at any time.
● The Lane Assist system does not detect all
road markings. The road surfaces, road struc-
tures or objects in poor condition can be in-
correctly detected as road markings under
certain circumstances by the Lane Assist sys-
tem. In such situations, switch the Lane As-
sist system off immediately.
● Please observe the indications on the in-
strument panel and act as is necessary.
● Always pay attention to the vehicle's sur-
roundings.
● When the area of vision of the camera be-
comes dirty, covered or is damaged, the Lane
Assist system function can be affected. CAUTION
In order to avoid influencing the operation of
the system, the following points must be tak-
en into account:
● Regularly clean the area of vision of the
camera and keep it in a clean state, without
snow or ice.
● Do not cover the area of vision of the cam-
era.
● Check that the area of vision of the wind-
screen camera is not damaged. Note
● The Lane Assist system has been exclusive-
ly developed for driving on paved roads only.
● If the Lane Assist system does not work as
described in this chapter, do not use it and
contact a specialised workshop.
● If there is a fault in the system, have it
checked by a specialised workshop. 166

Driver assistance systems
Switching off the Lane Assist system
in the following situations Due to the limits of the Lane Assist system,
switch it off in the following situations:
● When more attention is required of the
driver
● When driving in a sporty style
● In unfavourable weather conditions
● On roads in poor condition
● In areas of road works Note
The Lane Assist system deactivates when
driving below 60 km/h (40 mph). SEAT driving modes (SEAT Drive
Profile)*
Introduction SEAT Drive Profile enables the driver to
choose between four profiles or modes,
Nor-
mal , Sport
, Eco
and Individual
, that modify the
behaviour of various vehicle functions, pro-
viding different driving experiences. In the FR and X-PERIENCE models equipped
with dynamic chassis control and Navi Sys-
tem Plus, the
Comfort profile is also availa-
b l
e.
In the Leon Cupra model the four profiles are Comfort, Sport, Cupra and Individual.
The Individual profile can be configured ac-
cor

ding to personal preferences. The other
profiles are fixed.
Description Depending on the equipment fitted in the ve-
hicle, SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when
Eco
mode is selec-
ted, the Start-stop function is automatically
activated.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco1)
mode activates the In- ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles,
Eco1)
mode cau-
ses the gear change recommendation indica-
tions that appear on the instrument panel to
vary, facilitating more efficient driving.
Dynamic chassis control (DCC)
DCC continuously adapts the shock absorb-
ers to the condition of the road and current
driving conditions, according to the pre-set
programme.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: damping setting.
Address
Power steering becomes more robust in Sport
mode to enable a sportier driving style. In the
Leon Cupra the power steering becomes
more robust in Cupra mode.
Air conditioning
In vehicles with Climatronic, this can operate
in eco 1)
mode, especially restricting fuel con-
sumption. »1)
In the Leon Cupra model, Eco mode is selected
through the Individual profile.

P aint
damage Minor damage to the paint, such as scratches
or stone chips, should be touched up without
delay
before the metal starts to corrode. Suit-
ab l

e touch-up brushes or sprays for your car
can be obtained from a SEAT Official Service.
The number of the original paint finish on the
vehicle is given on the data sticker
››› page 241
.
If corrosion is already visible it must be thor-
oughly removed by a specialised workshop.
Windows Clear vision is an essential safety factor.
The windscreen must not be cleaned with in-
sect remover or wax, otherwise the wind-
screen wipers will not function properly (jud-
dering).
Traces of rubber, oil, grease or silicone can
be removed with a
window cleaning solution
or a silicone remover. Wax residue can only be remo
ved with a special cleaner. Your SEAT
Official Service will be able to provide you
with more detailed information.
The windows should also be cleaned on the
inside at regular intervals.
Use a separate cloth or chamois to dry the
windows. Cloths used for waxing and polish-
ing contain residues that will cause smears
on the glass. WARNING
Do not use water-repellent coatings on the
windscreen. In bad visibility conditions (e.g.
in the rain, dark or with a low sun), these
coatings may cause dazzle: risk of accident!
Such coatings can also cause the windscreen
wiper blades to make noise. CAUTION
● Remove snow and ice from windows and ex-
terior mirrors with a plastic scraper only. To
avoid scratches caused by dirt on the glass,
the scraper should only be pushed in one di-
rection and not moved to and fro.
● The heating element for the rear window is
located on the inner side of the window. To
avoid damaging them, do not apply stickers
to these heating elements.
● Never use warm or hot water to remove
snow and ice from windows and mirrors. This
could cause the glass to crack! Wheels
The wheels require regular attention to pre-
serve their appearance. It is important to re-
move road salt and brake dust by washing
the wheels at regular intervals, otherwise the
finish will be impaired.
After washing, the wheels should only be
cleaned with an "acid-free" cleaning agent
for alloy wheels. This is available from SEAT
Official Services and specialist retailers. Nev-
er leave the cleaning agent on the rims for
any longer than specified in the instructions
before rinsing it off. If the wheel cleaner fluid
contains acid it can attack the surfaces of the
wheel bolts.
Car polish or other abrasive agents should
not be used for maintaining the rims. If the
protective coating is damaged, e.g. by flying
stones, the damaged area should be re-
paired immediately.
WARNING
Please note when cleaning the wheels that
water, ice and road salt can impair the effec-
tiveness of the brakes; this can cause an acci-
dent. Exhaust tail pipe

Checking and refilling levels
Check the water level in the windscreen
washer reservoir regularly and top up as re-
quired.
The container for the windscreen washer con-
tains the cleaning fluid for the windscreen,
the rear window and the headlight washer
system*.
● Open the bonnet  ››› page 198.
● The windscreen washer reservoir is marked
with the symbol  on the cap.
● Chec k
there is enough windscreen water in
the reservoir.
Recommended windscreen wipers
● For the hottest seasons we recommend
summer G 052 184 A1 for clear glass. Propor-
tions of the mixture in the washer fluid tank:
1:100 (1 part concentrate per 100 parts wa-
ter).
● All year round, G 052 164 A2 for clear
glass. Approximate proportion of the winter
mixture, up to -18°C (0°F): 1:2 (1 part con-
centrate per 2 parts water); otherwise, a 1:4
proportion of mixture in the washer fluid
tank.
Top-up quantities
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 contain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contains enough anti-freeze.
● In cold conditions, you should not use the
windscreen washer 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
similar 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 reservoir. CAUTION
● Do not mix cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely certain that you fill the fluids into the
correct reservoirs. Using the wrong fluids could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
visibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery
General information The battery is located in the engine compart-
ment and is almost
maintenance-free. It is
checked as part of the Inspection Service.
Nevertheless, check the terminals are clean
and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in
exceptional cases. When the battery is dis-
connected, some of the vehicle's functions
are “lost” ( ››› table on page 206). These
functions will require resetting after the bat-
tery is reconnected.
Deactivate the anti-theft alarm* before you
disconnect the battery Otherwise the alarm
will be triggered. »

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.)

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.
