ing. If the vehicle is ap-
proaching an obstacle, an intermittent audi-
ble warning is emitted. The shorter the dis-
tance, the shorter the intervals between tones. If the vehicle is too close to the obsta-
cle, the audib

le warning becomes constant.

The button lights up when the function is
switched on.
Things to note on the parking distance warn-
ing system
● The parking distance warning system
sometimes r
egisters water on the sensors as
an obstacle.
● If the distance does not change, the warn-
ing sign
al will sound less loudly after a few
seconds. If the continuous signal sounds, the
volume will remain constant.
● When the vehicle moves away from the ob-
stac
le, the beeping sound automatically
switches off. On approaching the obstacle
again, the beeping sound will automatically
switch back on.
● If the electronic parking brake is engaged
or the selector l
ever is set to P, no audible
warning will be emitted. ●
Your tec
hnical service centre can adjust the
volume of the warning signals. Note
If the parking distance warning system is
fau lty

, a constant audible warning will be
emitted the first time it is switched on and
the button will flash. Switch the parking dis-
tance warning system off using the button
and take the vehicle to a specialised work-
shop to have the system checked as soon as
possible. 212

Operation
● Ob
ser
ve the surrounding area and acceler-
ate carefully at a maximum of 7 km/h
(4 mph).
● The park assist system is only r
esponsible
for moving the steering wheel during the ma-
noeuvre. The driver applies the accelerator,
the clutch, the gears and the brake.
● Follow the instructions given by the park
ass
ist system until the manoeuvre is comple-
ted.
● The park assist system steers the vehicle
forw
ards and backwards until it is in a
straight position in the parking space.
● The manoeuvre is complete when the corre-
sponding indic
ation is given on the instru-
ment panel display.
Stopping the parking manoeuvre
The park assist system stops the manoeuvre
in advance in the event of one of the follow-
ing:
● Press the  button.
● Driv

ing faster than 7 km/h (4 mph).
● The driver moves the steering wheel.
● The parking manoeuvre has not been com-
plet
ed after 6 minutes since the park assist
system was activated.
● A sliding door is opened. To restart the ma-
noeuvr e, c

lose the sliding door and press the
 button again. ●
There i s

a system malfunction (system tem-
porarily unavailable).
● The ASR system is switched off or the ASR
or ESC i
s working. WARNING
The steering wheel turns quickly by itself
when park in

g using the park assist system.
Placing your hand between the steering
wheel spokes could lead to injuries. Note
● The park a

ssist system has its limitations.
For example, it is not possible to park on
tight bends using the park assist system.
● Even if the park assist system recognises
that ther
e is not enough space for parking
the vehicle, the instrument panel display will
still show this place. In this case, the parking
manoeuvre should not be requested.
● Changing gears between forward and re-
verse g
ears before indicated (that is, before
the signal from the parking sensor system)
the parking results may not be ideal.
● For parallel parking (parallel to the road), a
sound wi
ll tell the driver when they must
change from forward gears to reverse; the
signal from the parking sensor system does
not indicate changes of direction.
● The park assist can also be activated after-
ward
s, if you pass close to a parallel parking
space at a maximum of 40 km/h (25 mph) or
close to a perpendicular parking space at about 20 km/h (12 mph) and then press the
 butt
on.
● The pr

ogress bar on the screen of the in-
strument p
anel shows a display of the rela-
tive distance to be covered.
● When the Park Assist system is turning the
steerin
g wheel of the stopped vehicle the 
symbol is also displayed. Press on the brake
pedal so that the steering can turn with the
vehicle at a standstill and thus reduce the
number of manoeuvres.
● A “suitable” parking space length is at
lea
st 1.1 m greater than the length of the ve-
hicle.
● If the results of the park assist system are
not as
good after changing the wheels, the
system must memorise the perimeter of the
new wheels. This process is performed auto-
matically while the vehicle is in motion. To
help this process, turn slowly (at less than
20 km/h [12 mph]), e.g. in an empty car park. Leaving a parking space using the
P

control of the steering and when traffic condi-
tions permit, leave the parking space.
Automatic stoppage of the manoeuvre
The park assist system stops the manoeuvre
in the event of one of the following:
● Driving faster than 7 km/h (4 mph).
● The driver moves the steering wheel.
● A sliding door is opened. To restart the ma-
noeuvre, c
lose the sliding door and press the
 button again.
● There is a system malfunction (system tem-
porarily
unavailable).
● The ASR system is switched off or the ASR
or ESC i
s working. WARNING
The steering wheel turns quickly automatical-
ly when l e

aving a parking space using the
park assist system. Placing your hand be-
tween the steering wheel spokes could lead
to injuries. Park Assist brake operation
The Park Assist system helps the driver by
brak
in

g automatically. Automatic braking
does not relieve the driver of responsibility
for controlling the accelerator, brake and
clutch ››› .
Br ak
in

g to avoid damage at excess speed
It is possible that the system operates the
brakes to reduce excess speed. The parking
manoeuvre can then continue. The brakes
will intervene during each parking process.
Braking to minimise damage
When approaching an obstacle, the vehicle
may brake automatically. In certain circum-
stances (e.g. storm, detection of ultrasounds,
vehicle status, load, inclination), the Park As-
sist system may stop the vehicle completely
before an object.
● Press the foot brake ››
›
!Following the intervention of the brakes, the
P
ark
As

sist will stop. WARNING
Despite the assistance provided by the park
as s

ist system, do not run any risks when
parking. The system is not a replacement for
driver awareness.
● Always be ready to brake.
● Automatic brake intervention will end after
1.5 seconds
approximately. Following auto-
matic intervention of the brakes, stop the ve-
hicle yourself. Rear assist* (Rear View Cam-

Operation
The CCS only slows down by reducing the ac-
c el
er
ator but not by braking ››› .
T r
av
elling down hills with the CCS
When travelling down hills the CCS cannot
maintain a constant speed. Slow the vehicle
down using the brake pedal and reduce
gears if required.
Automatic off
The cruise control system (CCS) is switched
off automatically or temporarily:
● If the system detects a fault that could neg-
atively aff
ect the operation of the CCS.
● If you drive above your set speed limit for a
long time.
● When action is

taken to adjust driving dy-
namics, e.
g. by the ASR and ESC.
● If the airbag is triggered.
● If the brake pedal is pressed.
● If, in the case of the DSG ®
dual clut
ch gear-
box, the selector lever is in the R, P or N posi-
tion.
● If, in the case of a manual gearbox, 1st
gear i
s engaged.
● If the clutch pedal is pressed for a long
time. WARNING
Use of the cruise control could cause acci-
dents and sev

ere injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the dis
tance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpav
ed roads.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
contro
l system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the pr
evailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a c
onstant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Lane Assist system*
Intr oduction WARNING
The intelligent technology in the lane assist
sys t

em cannot change the limits imposed by
the laws of physics and by the system itself.
Careless or uncontrolled use of the Lane As-
sist system may cause accidents and injury.
The system is not a replacement for driver
awareness.
● Always adapt your speed and the distance
to the v
ehicles 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 y
ou can turn it at any time.
● The lane assist system does not detect all
roa
d markings. In some circumstances, the
poor state of the road, structures located on
it or certain objects may be mistakenly recog-
nised as road markings by the lane assist
system. In such situations, switch the lane
assist system off immediately.
● Pay attention to the instructions on the in-
strument p
anel display and act accordingly to
its requests.
● Always pay attention to the vehicle's sur-
roundin

Schematic representation of the rear
c r
o

ss traffic alert: zone monitored around the
vehicle exiting the parking space. The rear cross traffic alert uses the radar sen-
sor
s
on the r

ear bumper ››› Fig. 222 to moni-
tor the traffic crossing behind the vehicle as
it backs out of a perpendicular parking space
or as it is being manoeuvred, for example in
very low visibility conditions.
If the system detects that someone else on
the road is approaching the rear of the vehi-
cle ››› Fig. 225, an acoustic alarm will sound. ●
In vehic
les without ParkPilot a “gong” will
sound and a message will be displayed on
the instrument panel.
● If the vehicle is equipped ParkPilot, the
ParkPilot
acoustic alarm will sound continu-
ously.
Automatic braking to reduce damages
If the rear cross traffic alert detects that
someone else on the road is approaching the
rear of the vehicle and the driver does not
step on the brake, the system will engage the
brakes automatically.
The parking system helps the driver by auto-
matically engaging the brakes to reduce any
damage. The system will brake automatically
if the vehicle is reversing at a speed of ap-
proximately 1-12 km (1-7 mph). Once it has
detected that the vehicle has stopped, the
system will keep the vehicle stopped for ap-
prox. 2 seconds.
After automatically braking to reduce dam-
age, the system will not be able to automati-
cally brake again for approximately 10 sec-
onds.
You can interrupt the automatic braking by
stepping forcefully on the accelerator pedal
or the brake pedal in order to regain control
of the vehicle. WARNING
The smart technology incorporated into the
re ar c

ross traffic alert cannot overcome the
limits imposed by the laws of physics; it only
works within the limits of the system. Do not
let the extra convenience afforded by the rear
cross traffic alert tempt you into taking any
risks. The system is not a replacement for
driver awareness.
● The system should never be used in limited
vis
ibility conditions or complicated traffic,
e.g., in high-traffic areas or when crossing
multiple lanes.
● Be sure to always be aware of the vehicle's
surrou
ndings, since the system is not guaran-
teed to detect things such as bicycles or pe-
destrians in all situations.
● The rear cross traffic alert itself will not
brake the
vehicle to a complete stop. Using the blind spot detector (BSD)

Operation
Note
● Alw a
ys turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 119. Otherwise, the tilt sensor may
erroneously activate the alarm.
● Never use a trailer with a new engine (for
the first
1,000 km or 600 miles) ››› page 247.
● At SEAT, we recommend folding in the tow
hitch b
all when a trailer is not being used. In
case of a rear collision, the damage caused to
the vehicle with the extended tow hitch ball
could be more extensive.
● In some models, a tow hitch is necessary
for to
wing vehicles. For this reason, you
should store the tow hitch in the vehicle at all
times. Technical requirements
If the car is supplied with a
fact
or
y-fitted tow-
ing bracket it will already have the necessary
technical modifications and meet the statuto-
ry requirements for towing a trailer.
Only use an approved tow hitch for the gross
trailer weight rating. The tow hitch must be
suitable for both the vehicle and trailer and
must be securely fitted to the vehicle chassis.
Only use a tow hitch with a removable ball
joint. Always check and take into account the
tow hitch manufacturer's instructions. Never
fit a trailer tow hitch “that distributes the
load” or “balances the load”. Bumper mounted tow hitch
Never fit a t

ow hitch or its attachments to the
bumper. A tow hitch should never interfere
with the bumper performance. Do not modify
the exhaust system and brake system. Regu-
larly check the tow hitch to ensure it is firmly
fitted.
Engine cooling system
Driving with a trailer increases the load on
the engine and cooling system. The cooling
system should always have sufficient coolant
and to be able to cope with the vehicle and
trailer.
Electric trailer brake
If the trailer has its own braking system,
please note the relevant legal requirements.
The trailer braking system should never be
connected to the vehicle braking system.
Trailer cable
Always use a cable between the vehicle and
the trailer ››› page 240.
Trailer rear lights
The rear lights of a trailer must fulfil the cor-
responding standards ››› page 240.
Never connect the trailer's rear lights directly
to the vehicle electric system. In case of any
doubt about the electrical connection of the trailer, ask a specialised workshop. SEAT rec-
ommends
visiting a technical service.
Wing mirrors
When the field of vision behind the trailer
cannot be seen using the standard wing mir-
rors of the towing vehicle, additional wing
mirrors are required according to the legal re-
quirements of each country. The wing mirrors
must be fitted before driving and must pro-
vide a sufficient field of vision behind.
Trailer electricity consumption
Never exceed the specifications:
DevicesMaximum power
Side lights and rear lights50 Watts
Turn signal (each side)54 Watts
Brake lights (total)84 Watts
Reversing lights (total)42 Watts
Rear fog light42 Watts WARNING
If the tow hitch is badly fitted or unsuitable,
the trai l

er may separate from the vehicle
causing an accident with serious consequen-
ces. 238

Towing bracket device
CAUTION
● If the r e
ar lights of the trailer are not cor-
rectly connected, the vehicle electronics may
be damaged.
● If the trailer absorbs excessive electric cur-
rent, the v
ehicle electronics may be dam-
aged.
● Never connect the trailer's electric system
to the electric
al connections of the rear lights
or any other power sources. Only use suitable
connections for providing electric current to
the trailer. Note
● To w

ing a trailer places additional demands
on the vehicle. At SEAT, we recommend addi-
tional services between the normal inspec-
tion intervals if the vehicle is used frequently
for towing a trailer.
● In some countries, an additional fire extin-
guisher is
required if the trailer weight is
more than 2500 kg Electric tow hitch ball*

The
v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. With the engine
running, electrical devices on the trailer re-
ceive power from the electrical connection
(pin 9 and pin 10 on the trailer power plug).
If the system detects that a trailer has been
connected electrically, the electrical equip- ment on the trailer will receive voltage
through this

connection (pins 9 and 10). Pin
9 has a permanent live. This powers, for ex-
ample, the trailer's interior lighting. Electrical
devices such as a fridge in a caravan only re-
ceive electrical power if the engine is running
(through pin 10).
The earth wires, pin 3 and pin 13, should not
be connected to each other to avoid over-
loading the electrical system.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available.
Trailer cable
Always secure the trailer cable to the towing
vehicle correctly. Leave a little bit of slack in
the cable for turning. However, ensure that
the cable does not rub off the ground while
driving.
Trailer rear lights
Check the trailer rear lights to ensure they
work correctly and remain legal. Ensure that
the trailer does not use more than the maxi-
mum power ››› page 238.
Trailer connected to the anti-theft alarm:
● When a vehicle comes from the factory fit-
ted w ith an anti-thef

t alarm and tow hitch. ●
When the trai l

er is connected to the vehicle
using the socket.
● When the vehicle and trailer electrical sys-
tems w
ork correctly and are not damaged.
● When the vehicle is locked using the vehi-
cle k
ey and the anti-theft alarm is turned on.
When the vehicle is locked, the alarm is trig-
gered when the electrical connection be-
tween the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer.
Otherwise, the tilt sensor may erroneously
activate the alarm.
Trailer with rear LED lights
For technical reasons, trailers fitted with rear
LED lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does
not trigger if the electrical connection with
the trailer is cut if it has rear light with light-
emitting diodes. WARNING
Erroneous or unsuitable connection of elec-
tric c ab

les may supply energy to the trailer
causing an anomaly in the vehicle electronics
that could result in an accident with serious
consequences.
● All work on the electrical system must be
carried out on
ly by a specialised workshop. » 241
