Operation
The function is intended to prevent collisions
w ith p
ark
ed vehicles or vehicles in the same
lane travelling in the same direction. It may
fail to activate in other danger situations.
The Front Assist function is active within a
range of speeds between 4 km/h (2.5 mph)
and 250 km/h (156 mph). Depending on
speed, traffic conditions and driver behav-
iour, some of the sub-functions described be-
low are omitted in order to optimise the sys-
tem’s general behaviour.
The Front Assist is a driving assistance func-
tion that can never replace the driver’s atten-
tion.
Safety distance warning
If the system detects a situation of danger
because the vehicle is too close to the vehi-
cle ahead, it will warn the driver by means of
an indication on the instrument panel display
.
The timing of the warning varies depending
on driver behaviour and the traffic situation.
Advance warning
If the system detects a possible collision with
the vehicle in front, it may alert the driver by
means of an audible warning and an indica-
tion on the instrument panel display
››› Fig. 189. The warning moment varies depending on
the traffic s
ituation 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 pre-warning
(advance warning), the system may actively
intervene in the brakes and generate a brief
jolt to warn the driver of the imminent danger
of a collision.
Automatic braking
If the driver also fails to react to the critical
warning, the system may initiate independ-
ent emergency braking by progressively in-
creasing the braking effect in accordance
with how critical the situation is.
Driver emergency brake assist system
Faced with an imminent collision, the system
may detect that the driver is not braking hard
enough to avoid the collision. In this case, it
will automatically increase the braking effect.
Due to certain driving circumstances and the
limitations of its operation, there are some
cases in which the system cannot prevent a
collision, although it can significantly mini-
mise the consequences by reducing the
speed and the force of the impact. WARNING
Observe the safety warnings ›››
in Control
and warnin g l
amps on page 101. WARNING
The Front Assist system cannot change the
la w

s of physics or replace the driver in terms
of keeping control of the vehicle and reacting
to a possible emergency situation. WARNING
Following a Front Assist emergency warning,
pa y

immediate attention to the situation and
try to avoid the collision by braking or by
dodging the obstacle, as applicable.
● If the Front Assist does not work as descri-
bed in this c
hapter (e.g. it repeatedly inter-
venes unnecessarily), switch it off.
● 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, occasionally
the Front As
sist may issue warnings and in-
tervene in braking unnecessarily, for example
at 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
may issue unnecessary warnings and inter-
vene inopportunely in the braking. 180

Driver assistance systems
●
The Front As
sist does not react to animals
or vehicles crossing your path or approaching
head-on down the same lane.
● The Front Assist does not react to pedes-
trians
walking in the same direction or ap-
proaching head-on down the same lane.
● The driver must always be ready to take
over the c
ontrol of the vehicle.
● When the Front Assist causes a braking,
the brake ped
al is “harder”.
● Automatic interventions by the Front Assist
on the brake
s may be interrupted by pressing
the clutch, accelerator or moving the wheel. Note
● When the Front As

sist is connected, the in-
dications on the instrument panel screen may
be concealed by warnings from other func-
tions, such as an incoming call.
● When the Front Assist causes a braking,
the brake ped
al is “harder”.
● Automatic interventions by the Front Assist
on the brake
s may be interrupted by pressing
the clutch, accelerator or moving the wheel.
● The Front Assist may brake the vehicle until
it st
ops completely. However, the brake sys-
tem does not halt the vehicle permanently.
Use the foot brake!
● If the Front Assist does not work as descri-
bed in this c
hapter (e.g. in intervenes several
times unnecessarily), switch it off. Have the
system checked by a specialised workshop.

affic situation
››› Fig. 190 1 .
The r a
d

ar 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 does not work. The instrument
panel displays the following message:
Front Assist: No sensor vision! If
necessary clean the radar sensor ››› .
When the r a
d

ar 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 the front of the vehicle is not properly re-
paired or structural modifications are made
to it, for example if the suspension is low-
ered, Front Assist operation may be affected.
SEAT recommends visiting a SEAT dealership
for this purpose. CAUTION
If you have the sensation that the radar sen-
sor is d

amaged or has lost its settings, dis-
connect the Front Assist. This will avoid pos-
sible dangerous situations caused by a sys-
tem malfunction. If this occurs have it adjus-
ted.
● The sensor may become damaged or lose
its settin
gs 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.
● A registration plate or plate holder on the
front th
at is larger than the space for the reg-
istration plate, or a registration plate that is
curved or warped can cause the radar to mal-
function.
● Clean away the snow with a brush and the
ice pref
erably with a solvent-free de-icer
spray. 181

System limitations The Front Assist has certain physical limita-
tions
inher

ent to the system. Thus, in certain
circumstances, some of the system's reac-
tions may be inopportune from the driver's
standpoint. So pay attention in order to inter-
vene if necessary.
The following conditions may cause the Front
Assist not to react or to do so too late:
● In the first few instants of driving after
swit c

hing on the ignition, due to the system’s
initial auto-calibration.
● On taking tight bends or complex paths.
● Pressing the accelerator all the way down.
● If the Front Assist is switched off or dam-
aged.
● If the ASR h

as been disconnected or the

Intr oduction The Fatigue detection informs the driver
when their driv
in
g beh

aviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Fatigue
detection sy s

tem tempt you into taking any
risks when driving. Take regular breaks, suffi-
cient in length when making long journeys.
● The driver always assumes the responsibil-
ity of driv
ing to their full capacity.
● Never drive if you are tired.
● The system does not detect the tiredness of
the driver in al
l circumstances. Consult the in-
formation in the section ››› page 186, System
limitations.
● In some situations, the system may incor-
rectly int
erpret an intended driving manoeu-
vre as driver tiredness.
● No warning is given in the event of the ef-
fect c
alled microsleep!
● Please observe the indications on the in-
strument p
anel and act as is necessary. Note
● Fatigue det ection h

as been developed for
driving on motorways and well paved roads
only.

System limitations
The Fatigue detection has certain limitations
inherent to the system. The following condi-
tions can limit the Fatigue detection or pre-
vent it from functioning.
● At speeds below 65 km/h (40 mph)
● At speeds above 200 km/h (125 mph)
● When cornering
● On roads in poor condition
● In unfavourable weather conditions
● When a sporty driving style is employed
● In the event of a serious distraction to the
driver Fatigue det

ection will be restored when the
vehicl
e is stopped for more than 15 minutes,
when the ignition is switched off or when the
driver has unbuckled their seat belt and
opened the door.
In the event of slow driving during a long pe-
riod of time (below 65 km/h, 40 mph) the
system automatically re-establishes the tired-
ness calculation. When driving at a faster
speed the driving behaviour will be recalcula-
ted. Towing bracket device
Driv in
g w
ith a trailer
Technical requirements If your vehicle has a factory-fitted towing
brac
k

et or is equipped with a selection of
SEAT Original Accessories, it meets all the rel-
evant technical and legal requirements.
In vehicles with a towing bracket it is possi-
ble to remove the ball joint, situated (togeth-
er with the special assembly instructions) in
the housing for the spare wheel in the vehi-
cle luggage compartment ›››
page 76, Vehicle
tool kit*.
Your vehicle is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the trailer you
are going to use has a 7-pin connector, the
corresponding adaptor, acquired from the
SEAT Original Accessories Catalogue, can be
used.
If a towing bracket is to be retro-fitted to the
car, it must be done according to the instruc-
tions of the towing bracket manufacturer. Note
Any queries that may arise can be directed to
an authorised S EA

T dealer.186

Towing bracket device
Trailer weight Trailer weight
The comb
ined
vehicle and trailer must be
balanced. To do so use the maximum permit-
ted towing bracket load. An insufficient
weight exerted by the trailer drawbar on the
ball joint of the towing bracket will have a
negative impact upon the response of the ve-
hicle-trailer assembly on the road.
Weight distribution
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Ensure that the objects do not move.
If the towing vehicle is empty and the trailer
loaded then the load distribution is incorrect.
However, if these conditions cannot be avoi-
ded, drive very slowly.
Tyre pressure values
Correct the tyre pressure in your vehicle to
“total load” ›››
page 218, Service life of
tyres.
Trailer weight
Never exceed the authorised trailer weight
under any circumstances ›››
page 223, Tech-
nical specifications .
The trailer weights listed are only applicable
for altitudes up to 1000 m above sea level.
Due to lower air density, engine power de- creases depending on the increase in alti-
tude, thi
s

also reduces climbing ability,
which requires a reduction of the weight of
the vehicle with a trailer by 10% for every
1000 m increase in altitude. The weight of
the assembly is calculated by adding the ve-
hicle weight (loaded) to the trailer weight
(loaded). Always drive with special care when
towing a trailer.
The towed load and support load information
that is displayed on the towing bracket man-
ufacturers label are only values for the verifi-
cation of the device. The correct figures for
your specific vehicle, which are usually lower
than these figures, are given in the documen-
tation of your vehicle. WARNING
● Exc eedin

g the maximum established load
per axle and the maximum towing bracket
load in addition to the maximum permitted
load or the load of the vehicle + trailer as-
sembly can cause accidents and serious inju-
ries.
● A sliding load can considerably affect the
stab
ility and safety of the vehicle + trailer as-
sembly, resulting in accidents and serious in-
juries. Driving with a trailer
Exterior mirrors
Check
whether

you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Observe the relevant statutory requirements
of the country you are in.
Headlights
Before starting a journey, also check the
headlight beam settings with the trailer
hitched up. Adjust the headlight range set-
tings if necessary ›››
page 122, Headlight
range control.
Driving speed
For your own safety do not drive faster than
the maximum permitted speed indicated on
the trailer.
At all times, immediately reduce speed if you
detect the slightest swaying movement of the
trailer. Never try to “return the trailer to a
straight position” by accelerating.
Brakes
Brake in due course! If the trailer has an over-
run brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that
can be caused by locking of trailer wheels.

Water in the fuel filter 1)
If
y
our vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. Engine compartment

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.
