Driving tips Driv in
g thr
ough flooded roadsTo prevent damage to the vehicle when driv-
ing thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edg
e of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc ., the br

aking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, running gear or electrical
system.
● Whenever driving through water, the Start-
Stop sys
tem* must be switched off
››› page 191. Note
● Check the depth of

the water before enter-
ing the flooded zone. ●
Do not s t

op in the water, drive in reverse, or
stop the engine in any situation.
● Note that vehicles travelling in the opposite
direction ma
y splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). Driver assistance systems

Adjusting distance level
The distance according to speed with regard
to the vehicle in front can be controlled on
the Easy Connect system on 5 levels
›››  page 27.
In wet road conditions, you should always set
a larger distance with regard to the vehicle in
front than when driving in dry conditions.
The following distances can be preselected:
● Very short
● Short
● Media
● Long
● Very long

Adjusting the driving programme
In vehicles with driving profile selection
(SEAT Drive Profile), the profile selected can
influence acceleration behaviour
››› page 219. The following driving programmes items can
be selected:
● Norm

al
● Sport
● Eco
In vehic
les without the driving profile selec-
tion function, acceleration behaviour can be
influenced by selecting a driving programme
on the Easy Connect system using the  button and the
S
ETUP and

 page 27.
The following conditions may lead the ACC
not to react:
● If the accelerator is pressed.
● If there is no gear engaged.
● If the ESC is controlling.
● If the driver is not wearing his/her seat
belt.
● If sev

eral brake lights of the vehicle or elec-
trically
connected trailer are damaged.
● If the vehicle is reversing.
● Driving faster than 210 km/h (150 mph). WARNING
There is a danger of rear collision when the
minimum dis t

ance to the vehicle in front is
exceeded and the speed difference between
both vehicles is so great that a speed reduc- tion by the ACC will not suffice. In this case
the brak
e ped

al should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions pr
operly.
● “Stepping” on the accelerator may cause
the ACC
not to intervene in braking. Driver
braking will have priority over intervention by
the speed control or adaptive cruise control.
● Always be ready to use the brakes!
● Observe country-specific provisions gov-
erning ob
ligatory minimum distances be-
tween vehicles. Note
● The progr ammed s

peed is erased once the
ignition or the ACC are switched off.
● When the traction control system (ASR) is
deactivat
ed during acceleration or else the
ESC is activated in Sport* Mode
( ››› page 110), the ACC switches off automati-
cally.

Operation
Narrow or misaligned vehicles
The r a
d
ar sensor can only detect narrow or
misaligned vehicles when they are within
range ››› Fig. 205 B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
Vehicles with special loads and accessories
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary.
Other vehicles changing lanes
Vehicles changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors.
Consequently, the ACC will take longer to re-
act ››› Fig. 206 C. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it ›››
Fig. 206 D. In these ca ses, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles approach-
ing from the opposite direction or vehicles
crossing your path.
Metal objects
Metal objects, e.g. rails on the road or sheets
used in road works, can confuse the radar
sensor and cause the ACC to react wrongly.
Factors that may affect how the radar sensor
operates
If laser sensor operation is impaired, due to
heavy rain, spray, snow or mud, the ACC is
deactivated temporarily. The relevant text
message will appear in the dash panel dis-
play. If necessary, clean the radar sensor.
When the radar sensor begins to operate
properly again, the ACC will automatically be
available again. The message on the instru-
ment panel screen will switch off and the ACC
will be reactivated again.
ACC operation may be affected by a strong ra-
dar reverse reflection, for example in a closed
car park. Trailer mode
When driving w
ith trailer the ACC controls
less dynamically.
Overheated brakes
If the brakes overheat, for example after
abrupt braking or in long and steep slopes,
the ACC may be deactivated temporarily. The
relevant text message will appear in the dash
panel display. In this case, adaptive cruise
control cannot be activated.
Adaptive cruise control can be reactivated
once brake temperature has cooled suffi-
ciently. The message will disappear from the
instrument panel display. If the message ACC
not available remains on for quite a long
time it means that there is a fault. Contact a
specialised workshop. SEAT recommends vis-
iting a SEAT dealership. WARNING
If the message ACC ready to start ap-
pear s

on the instrument panel display and
the vehicle in front starts up, the vehicle will
start up automatically. In this case the radar
sensor may not detect obstacles on the road.
This could cause an accident and serious in-
juries.
● Before driving off, check that the road is
cle
ar. If necessary, apply the brake. 206

Operation
Depending on the infotainment system in-
s t
al
led in the vehicle, the advance warning
function may be adjusted as follows:
● Ready
● Medium
● Delayed
● Deactivated
SEAT r
ecommends driving with the function
in “Medium” mode.
Switching distance warning on and off
If the safe distance with regard to the vehicle
in front is exceeded, the relevant warning will
appear on the instrument panel display
. In this case, increase the safe dis-
tance.
The distance warning may be switched on
and off in the Easy Connect system using
the  button and the
S
ETUP and
Driv er a
s

sistance function buttons

 page 27.
The system will store the setting for the next
time the ignition is switched on.
SEAT recommends keeping the distance
warning switched on at all times. Switch Front Assist off in the following
situation

s In the following situations the Front Assist
Monitorin
g

System should be deactivated
due to the system's limitations ››› :
● When the vehicle is to be towed.
● If the vehicle is on a test bed.
● When the radar sensor is damaged.
● If the radar sensor takes a heavy knock, for
ex amp

le in a rear collision.
● If it intervenes several times unnecessarily.
● If the radar sensor is covered temporarily
with some k ind of

accessory, such as an ad-
ditional headlight or the like.
● When the vehicle is to be loaded on a lorry,
ferry
or train. WARNING
If the Front Assist is not switched off in the
sit uation

s described, serious accidents and
injuries may occur.
● Switch off the Front Assist in critical situa-
tions. System limitations
Front Assist has certain physical limitations
inher
ent in the sy

stem. Thus, in certain cir-
cumstances some of the system's reactions may be inopportune or be delayed from the
driver's s

tandpoint. So pay attention in order
to intervene if necessary.
The following conditions may cause Front As-
sist not to react or to do so too late:
● On taking tight bends.
● Pressing the accelerator all the way down.
● If the Front Assist is switched off or dam-
aged.
● If the ASR h

as been manually disconnec-
ted.
● If the E

SC is controlling.
● If several brake lights of the vehicle or elec-
trically
connected trailer are damaged.
● If the radar sensor is dirty or covered.
● If there are metal objects, e.g. rails on the
roa
d or sheets used in road works.
● If the vehicle is reversing.
● If the vehicle over-accelerates.
● In case of snow or heavy rain.
● In case of narrow vehicles, such as motor-
bike
s.
● Misaligned vehicles.
● Vehicles crossing the other's path.
● Vehicles approaching in the opposite direc-
tion.

The Fatigue detection informs the driver
when their driving behaviour 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 sys t

em does not detect the tiredness of
the driver in all circumstances. Consult the in-
formation in the section ››› page 225, 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.
● If there is a fault in the system, have it
check
ed by a specialised workshop.224

Operation
WARNING
● Alw a
ys pay attention, also when looking
straight ahead, to traffic and the vehicle
surroundings. The assistance systems are not
a replacement for driver awareness. When in-
serting or removing the vehicle from a park-
ing space, or when performing similar ma-
noeuvres the driver always assumes the re-
sponsibility.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions.
● The ultrasound sensors have blind spots in
which ob
stacles and people are not regis-
tered. Pay special attention to children and
animals.
● Always keep visual control of the vehicle
surrou
ndings: use the mirrors for additional
help. CAUTION
Parking Aid functions may be negatively af-
fect ed b

y different factors that may lead to
damage to the vehicle or its immediate sur-
rounds:
● Under certain circumstances, the system
does not
detect or display certain objects:
– Objects such as chains, trailer draw bars,
fences, posts and thin trees.
– Objects that are located above the sen-
sors, such as protrusions in a wall. –
Ob j

ects with certain surfaces or struc-
tures, such as wire mesh fences or pow-
der snow.
● Certain surfaces of objects and garments
do not refl
ect the ultrasound sensors' sig-
nals. The system cannot detect, at least cor-
rectly, these objects or people wearing such
clothes.
● Ultrasound sensor signals may be affected
by e
xternal sound sources. In certain circum-
stances this may prevent them from detect-
ing people or objects.
● Please note that low obstacles detected by
the syst
em may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. In
certain circumstances, objects such as high
kerbs that could damage the bottom of the
vehicle are not detected either.
● If the first warning from the ParkPilot is ig-
nored, the v
ehicle could suffer considerable
damage.
● The knocks or damage on the radiator
grill
e, bumper, wheel arch and vehicle under-
body can adjust the orientation of the sen-
sors. This can affect the parking aid function.
Have the function checked by a specialised
workshop. Note
● In cer t

ain situations, the system can give a
warning even though there is no obstacle in
the detected area, e.g: –
with r ough or c

obbled floors or ground
with long grass;
– with external ultrasound sources, such as
cleaning vehicles or other vehicles;
– In downpours, intense snow or dense ex-
haust gases;
– if the registration plate (front or rear) is
not properly affixed to the bumper sur-
face;
– or in locations such as the brow of a hill.
● In order to guarantee good system opera-
tion, keep the ultr
asound sensors clean, free
of snow or ice, and do not cover them with
adhesives or other objects.
● If you use high-pressure or vapour equip-
ment to c
lean the ultrasound sensors, apply
it directly only very briefly and always from a
distance of more than 10 cm.
● Retrofitting of accessories to the vehicle,
such a
s a bicycle rack, may interfere with the
operation of the Parking Aid.
● In order to familiarise yourself with the sys-
tem, it i
s advised that you practice parking in
an area or car park that is free from traffic.
There must be good weather and light condi-
tions.
● The volume and tone of the warnings can
be modified, in addition t
o the indications
››› page 230.
● In vehicles without a driv
er information
system, these parameters can be modified in
a SEAT Official Service or in a specialised
workshop. 226

Description
There are sensors integrated in the rear
bumper. When the sensors detect an obsta-
cle, you are alerted by audible warnings.
Make particularly sure that the sensors are
not covered by adhesives, residues and the
like, as this could affect the system's opera-
tion. Cleaning instructions ››› page 248.
The approximate measurement range of the
rear sensors is:

v
al
betw

een the audible warnings will be re-
duced. When you reach around 0.30 m the
warning will be constant: Do not continue to
move forward (or backward) ››› in Generalinformation on page 226,
