g while you are driving, the signal
with the additional rain sign will be
shown first, on the left, as it is the one
that is applicable at the time.
A sign valid only with restrictions, e.g.
No overtaking at certain times, will be
displayed third ››› Fig. 211 C.
Town or city entrance and exit signs activate
the display of current speed limits in the
country's cities or roads. If there is an addi-
tional speed limit sign next to the town or
city entrance and exit signs, this sign will al-
so be displayed.
Signs indicating the end of a speed limit or
the end of an overtaking prohibition are not
displayed.
No warning will be given if the speed limit
sign displayed is exceeded. The correspond-
ing legal provisions are applicable.

table on page 2
The Tiredness detection informs the driver
when their driving behaviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Tired-
nes s

detection system tempt you into taking
any risks when driving. Take regular breaks,
sufficient in length when making long jour-
neys.
● The driver always assumes the responsibil-
ity of driv
ing to their full capacity. ●
Never driv e 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 211, 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
● Tiredne s

s detection has 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.210

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 rear vision 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 Park Pilot 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 carrier, 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 216.
● In vehicles without a driv
er information
system, these parameters can be modified in
a SEAT Official Service or in a specialised
workshop. 212

Towing bracket device
Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 228.
Connectors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re- duced by 10% for every further 1000 m (or
par
t

thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving.
Tyre pressure
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. 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.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 226.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 226. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 225

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading 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

Operation
Anti-theft alarm system When the vehicle is locked, the alarm is trig-
ger
ed when the el
ectrical connection be-
tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 121.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al

arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated.CAUTION
For technical reasons, trailers fitted with rear
LED lights ar

e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra
c
ar e. W

eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 108. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.
