Driver assistance systems
If the vehicle is equipped with automatic
g e
arbo
x, the ACC can brake the vehicle until
it stops completely if a vehicle in front of it
stops.
Driver intervention prompt
During driving, the ACC is subject to certain
limitations inherent in the system. In other
words, in certain circumstances the driver will
have to adjust speed him or herself, as well
as the distance from other vehicles.
In this case, the instrument panel screen will
warn you to intervene by applying the brake
and a warning tone will be heard
››› page 198. WARNING
The intelligent technology in the ACC cannot
ov er

come the system's inherent limitations
or change the laws of physics. If used negli-
gently or involuntarily, it may cause serious
accidents and injuries. The system is not a re-
placement for driver awareness.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● Do not use the ACC when visibility is bad,
on steep r
oads, with several bends or in slip-
pery circumstances such as snow, ice, rain or
loose gravel, or on flooded roads.
● Never use the ACC when driving off-road or
on unpav
ed roads. The ACC has been de-
signed for use on paved roads only. ●
The AC C

does not react on approaching a
fixed obstacle, such as the tail of a traffic
jam, a damaged vehicle or a vehicle stopped
at the traffic lights.
● The ACC only reacts to people if a pedes-
trian monitorin
g system is available. In addi-
tion, the system does not react to animals or
vehicles crossing your path or approaching
head-on down the same lane.
● If the ACC does not reduce speed sufficient-
ly, brak
e the vehicle immediately by applying
the pedal.
● If you are driving using the spare wheel,
the ACC
system could automatically switch
off during the journey. Switch off the system
when starting off.
● If the vehicle continues to move involuntar-
ily af
ter a driver intervention prompt, brake
the vehicle by applying the pedal.
● If the dash panel displays a driv
er interven-
tion prompt, adjust the distance yourself.
● The driver should be ready to accelerate or
brake b
y him/herself at all times. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged, disconnect the ACC. This will
avoid possible damage. If this occurs have it
adjusted.
● Repairs to the radar sensor require special-
ist
knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. Note
● If the A C

C system does not work as descri-
bed in this chapter, do not use it until it has
been checked by a specialised workshop.
SEAT recommends visiting a SEAT dealership
for this purpose.
● Maximum speed with the ACC activated is
limited to 210 km/h (150 mph).
● When the A

CC is switched on, strange
noises
may be heard during automatic brak-
ing cause by the braking system. 197

Driver assistance systems
Front Assist system including
C ity
emer
gency braking and
pedestrian monitoring*
Introduction 

›› ›

table on page 2
The Front Assist system including City emer-
gency braking and pedestrian monitoring can
help avoid collisions.
The Front Assist system may warn the driver,
within the constraints of the system, of im-
pending collisions, prepare the vehicle for
emergency braking in case of danger, provide
support during braking and apply automatic
braking.
The City emergency braking and pedestrian
monitoring functions are an integral part of
the Front Assist system.
The Front Assist is not a replacement for
driver awareness.
Distance warning
If the system detects that safety is endan-
gered by the proximity of the vehicle in front,
it may warn the driver by means of a message
on the instrument panel when driving at a
speed of between approximately 60 km/h
(37 mph) and 250 km/h (156 mph)
››› Fig. 207. The warning moment varies depending on
the traffic
s

ituation and driver behaviour.
Advance warning
If the system detects a possible collision with
the vehicle in front, it may warn the driver by
means of an audible warning and an indica-
tion on the instrument panel when driving at
a speed of between approximately 30 km/h
(18 mph) and 250 km/h (156 mph)
››› Fig. 207.
The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking ››› .
C ritic
a

l warning
If the driver fails to react to the advance
warning, the system may actively intervene in
the brakes when driving at a speed of be-
tween approximately 30 km/h (18 mph) and
250 km/h (156 mph), generating a brief jolt
to warn of the imminent collision.
Automatic braking
If the driver also fails to react to the advance
warning, the system may brake the vehicle
automatically, by progressively increasing
braking effect driving at a speed of between
approximately 4 km/h (2.5 mph) and
250 km/h (156 mph). By reducing speed in
case of a possible collision, the system may contribute to reducing the consequences of
an accident

.
Front assist
If the Front Assist notices that the driver is
not braking sufficiently in case of a collision
hazard, the system can increase braking ef-
fect and thus avert the collision when driving
at a speed of between approximately 4 km/h
(2.5 mph) and 250 km/h (156 mph). Front
assist only acts while the brake pedal is
pressed down hard. WARNING
The intelligent technology in the Front Assist
cannot c

hange the laws of physics. The driver
is always responsible for braking in time. If
the Front Assist issues a warning, then, de-
pending on the traffic circumstances, you
must brake immediately or dodge the obsta-
cle.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● The Front Assist alone cannot avoid acci-
dents and seriou
s injuries.
● In complex driving situations, the Front As-
sis
t may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.
● If the operation of the Front Assist is im-
paired, f
or example, by dirt or because the ra-
dar sensor has lost its settings, the system » 207

If the system detects a possible collision with
a vehicle in front of it, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er f

ails to react to a possible colli-
sion, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.

Operation
If the driver continues to do nothing, the sys-
t em aut
om
atically takes over the accelerator,
brakes and steering in order to brake the ve-
hicle and keep it in its lane ››› . If the re-
m ainin
g br

aking distance is sufficient, if nec-
essary the system slows down the vehicle un-
til it stops completely and automatically
switches on the electronic parking brake
››› page 172.
When the Emergency Assist is actively adjust-
ing, the hazard warning lights come on
››› page 135 and the vehicle makes slight zig-
zag movements in the lane in order to warn
other drivers.
Switching the Emergency Assist on and off
The Emergency Assist is switched on auto-
matically when the Lane Assist is switched on

Introduction 

›› ›

table on page 2
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 func-
tions, providing different driving experiences.
In the FR and X-PERIENCE models equipped
with dynamic chassis control, the Comfort
profile is also available.
In the Leon Cupra model the four profiles are Comfort , Sport, Cupra and Individual .
The Individual profile can be configured
according to personal preferences. The other
profiles are fixed. Description Depending on the equipment fitted in the ve-
hicl
e,

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 Eco 1)
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)

››› table on page 2 DCC continuously adapts the shock absorb-
ers

o 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 .

Care and maintenance
Plastic parts Plastic parts are cleaned with a power wash-
er. If
thi
s is not sufficient, plastic parts
should only be treated with a special solvent-
free plastic cleaning agent . Do not use paint-
work cleaners, polishes or wax on plastic
parts.
Carbon parts The carbon parts on your vehicle have a pain-
t
ed s
ur

face. They do not need any special
care and are cleaned just like any other pain-
ted part ›››
page 246.
Paint damage Minor damage to the paint, such as scratches
or s
t
one c

hips, should be touched up without
delay before the metal starts to corrode. Suit-
able 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 281.
If corrosion is already visible it must be thor-
oughly removed by a specialised workshop. Windows Clear vision is an essential safety factor.
The wind
s

creen 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 removed 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
wind s

creen. 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
● Remo v

e snow and ice from windows and ex-
terior mirrors with a plastic scraper only. To avoid scratches caused by dirt on the glass,
the sc
r

aper 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 s
ide 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 ic
e from windows and mirrors. This
could cause the glass to crack! Wheels
The wheels require regular attention to pre-
ser
v
e their ap

pearance. 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. »

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
