Automatic deactivation of the blind spot de-
tector (BSD)
The radar sensors of the blind spot detector
with rear cross traffic alert will be automati-
cally deactivated when, among other rea-
sons, one of the sensors is detected to be
permanently covered. This may be the case if,
for example, there is a layer of snow or ice in
front of one of the sensors.
The relevant text message will appear in the
dash panel display Trailer mode
The Blind spot det

ector and the rear cross
traffic alert will be automatically deactivated
and it will be impossible to activate them if
the tow hitch is electrically connected to a
trailer or other similar object.
As soon as the driver starts to drive with a
trailer connected electrically to the vehicle, a
message will appear on the instrument panel
display indicating that the blind spot detec-
tor and the rear cross traffic alert are deacti-
vated. Once the trailer has been unhitched
from the vehicle, if you want to use the blind
spot detector and the rear cross traffic alert,
you will have to reactivate them in the corre-
sponding menu.
If the towing hitch is not factory equipped,
then the blind spot detector and the rear
cross traffic alert will have to be deactivated
manually when driving with a trailer.
Traffic signal detection
(Sign Assi

st)*
Introduction Sign Assist can help the driver with informa-
tion on s
peed limits
or if

overtaking is pro-
hibited at that moment. The traffic signs and
additional information detected by the sys-
tem is represented in the dash panel display and in the visual presentation of the naviga-
tion syst

em map.
Applicable countries:
Sign Assist is accepted in the following coun-
tries:
Andorra, Belgium, Denmark, Germany, Fin-
land, France, Ireland, Italy, Liechtenstein,
Luxembourg, Monaco, Netherlands, Norway,
Austria, Poland, Portugal, San Marino, Swe-
den, Switzerland, Spain, Czech Republic, Uni-
ted Kingdom, Vatican City. WARNING
The traffic signs and instructions shown by
Sign Ass i

st may differ from the current traffic
situation.
● The signs and highway code rules always
take pr
ecedence over the instructions and
display of Sign Assist.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
● The system cannot always detect or cor-
rectly sho
w all the traffic signs. WARNING
The traffic sign detection is not a replacement
for driv er a

wareness.
● Adverse conditions of visibility, darkness,
snow
, rain and fog can cause the system not
to show the traffic signs or to show them er-
roneously. » 227

Display of traffic signs
Speed limits or overtaking prohibitions to-
gether with the corresponding additional
signs are shown on the instrument panel dis-
play ›››
Fig. 225. Depending on the naviga-
tion system installed in the vehicle, traffic
signs will be shown as above and also in the
navigation system's map display.
When Sign Assist is connected, the vehicle
records the traffic signs with a camera in the
base of the interior rear vision mirror. After
checking and evaluating the information
from the camera, the navigation system and
the current vehicle data, up to three valid
traffic signs are displayed in conjunction with
the corresponding additional signs. The traf-
fic sign that is currently valid for the driver is
shown first, in the left side of the screen. A
traffic sign of only limited validity,
e.g. 90 km/h (56 mph) is shown second, to-
gether with the additional sign “if the road is wet”. If the vehicle's rain sensor detects rain
during tr
av

el, the traffic sign valid at this mo-
ment will move to the first position along the
additional sign “if the road is wet”.
The permanent display on the instrument
panel screen is shown as you pass the real
traffic signs. The signs for entering and leav-
ing towns activate the display of the usual
speed limits for that country on roads in
populated areas and national highways, even
if the speed is not limited by an actual traffic
sign.
The end of a prohibition or limitation is not
displayed. If you exceed the speed limits
shown, a warning will not appear. The system
does not detect areas with little traffic. The
current legal provisions apply.

If the w arnin
g lamp  lights up, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sure
s or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pr
essure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all
of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label ››› Fig. 251.
● The tyre monitoring system can only oper-
ate corr
ectly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can dam
age them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyre
s to the correct pressure.
● If tyre pressure is too low then the tyre is
subj
ect to greater forces and it may be heated
to such an extent that the tread can rupture
and the tyre will burst.
● With an overloaded vehicle at high speed,
the tyre
s can overheat and burst resulting in
a loss of vehicle control.
● Tyre pressures which are too high or too
low reduc
e the useful life of the tyre, affect-
ing vehicle performance. ●
If a ty r

e has not been “punctured” and does
not have to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. Tyre monitoring indicator

Adaptation of the tyre monitoring indicator
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 228 button on the
tyre monitoring indicator must be kept press-
ed down, with the ignition on, until an audi-
ble warning is heard. Do the same, for exam-
ple, when the front and rear wheels are swap-
ped ››› Fig. 250.
If the wheels are subjected to an excessive
load (towing a trailer, heavy load), the tyre
pressure must be increased to the maximum
recommended pressure ››› page 284. Press

Driv in
g w
ith a trailer
Introduction Always be aware of the legal requirements for
eac
h c

ountry to drive with a trailer and to use
a tow hitch.
Your car is intended mainly for transporting
passengers however, it can also be used to
tow a trailer provided that it is fitted with the
necessary equipment. The additional load
has an effect on the useful life, fuel con-
sumption and the vehicle performance and,
in some cases, reduce the service intervals.
Driving with a trailer requires more force from
the vehicle and, thus, more concentration
from the driver.
For wintertime temperatures, fit winter tyres
to the vehicle and the trailer.
Drawbar load
The maximum permitted Drawbar load exer-
ted by the trailer drawbar on the ball joint of
the tow hitch must not exceed 100 kg (ap-
proximately 220 lbs).
Vehicles with the Start-Stop function
With a SEAT factory fitted or retrofitted tow
hitch, the Start-Stop function is automatically deactivated when a trailer is connected. For
to
w hit

ches not installed by SEAT, the Start-
Stop function must be deactivated manually
using a button located on the dash panel be-
fore driving with a trailer and it must remain
off for the entire journey ››› .
WARNING
Never transport people in a trailer: this will
endan g

er in their life and is against the law. WARNING
The incorrect use of the tow hitch can cause
acc ident

s and injury.
● Only use a tow hitch in perfect condition
and correctly
installed.
● Never change or repair a tow hitch.
● To reduce the risk of injury in case of a re-
vers
ing collision, injury to pedestrians and
cyclists when parking, always keep the ball
joint in when a trailer is not being used.
● Never fit a trailer tow hitch “that distrib-
utes
the load” or “balances the load”. Your
vehicle has not been designed for this type of
tow hitch. The tow hitch may fail and the
trailer will separate from the vehicle. WARNING
Driving with a trailer and transporting heavy
or lar g

e objects can affect vehicle handling
and even cause an accident. ●
Alw a

ys secure loads correctly with suitable
and undamaged attachment rope or straps.
● Adjust your speed and driving style to visi-
bility
, road, traffic and weather conditions.
● Trailers with a high centre of gravity can
over
turn more easily than those with a low
centre of gravity.
● Avoid brusque manoeuvres and sudden
brakin
g.
● Always take the following precautions seri-
ously
.
● Reduce your speed immediately if you ob-
serve the tr
ailer rocking from side to side.
● Never drive at more than 80 km/h (50 mph)
when tow
ing a trailer (or 100 km/h [62 mph]
in exceptional circumstances). This also ap-
plies in countries where higher speeds are
permitted. Always take the speed limits for
vehicles with and without trailers in each
country into account.
● Never try to stop the “snaking” by increas-
ing speed. WARNING
When driving with a trailer and using a tow
hitc h th

at was not installed by SEAT, the
Start-Stop function must be manually deacti-
vated. Otherwise, this could cause a braking
anomaly that could result in an accident with
serious consequences.
● Always manually deactivate the Start-Stop
function when a tr
ailer is being used on a tow
hitch that has not been installed by SEAT. 234

Towing bracket device
Note
● Alw a
ys turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 117. 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 244.
● 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 237.
Trailer rear lights
The rear lights of a trailer must fulfil the cor-
responding standards ››› page 237.
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. » 235

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

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 235.
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.238

●
Never c onnect
the trailer's electric system
to the electrical connections of the rear lights
or any other power sources. CAUTION
Do not leave the trailer connected to the vehi-
c le when p

arked; places on its support wheel
or its supports. For example, when changing
the load or a puncture, the vehicle will be
pushed up or down. The force acting on the
tow hitch and the trailer could damage the
vehicle or the trailer. Note
● In the event of

a fault in the vehicle or trail-
er electrical system or in the event of prob-
lems with the anti-theft alarm system, have
the system checked by a specialised work-
shop.
● If the trailer accessories use energy from
the power soc
ket when the engine is stop-
ped, the battery will be discharged.
● For technical reasons, trailers fitted with
rear LED light
s cannot be connected to the
anti-theft alarm system.
● If the vehicle battery is running low, the
electrica
l connection with the trailer is auto-
matically cut.
● With the engine running, the electrical
equipment on the trai
ler will be supplied with
power. Loading the trailer
Trailer weight / drawbar load
The trai
l

er weight is the load that the vehicle
can pull ››› . The drawbar load is the vertical
weight of

the tow hitch on the tow hitch ball
››› page 242.
The figures for trailer weights and drawbar
load weights given on the data plate of the
tow hitch are for values of this model only.
The correct figures for your specific vehicle,
which may be lower than these figures for the
tow hitch, are given in the vehicle documen-
tation. The instructions in the official vehicle
documents take precedence.
For the sake of road safety, SEAT recom-
mends using the maximum allowed drawbar
load. The handling of the combined vehicle
and trailer will be poor if the drawbar load is
too low.
The drawbar load increases the weight on the
rear axle, reducing the vehicle carrying ca-
pacity.
Gross combination weight
This figure refers to the combined weight of
the loaded vehicle and loaded trailer.
Loading the trailer
The combined vehicle and trailer must be
balanced. Use the maximum drawbar load authorised and do not overload the front or
the re
ar of

the trailer:
● Distribute loads in the trailer so that heavy
obj
ects are as near to the axle as possible or
above it.
● Correctly secure the trailer load.
Tyr
e pressure
Inflate the trailer tyres according to the man-
ufacturer's instructions.
Inflate the towing vehicles tyres to the maxi-
mum ››› page 284. WARNING
Exceeding the maximum authorised axle
loa d, dr

awbar load or the gross combination
weight of the towing vehicle and trailer could
cause a serious accident with severe conse-
quences.
● Never exceed the specifications.
● With the actual load on the front and rear
axle
s, the maximum axle load should never
be exceeded. The weight on the front and rear
should never exceed the gross vehicle
weight. WARNING
If the load moves, the stability and safety of
the v ehic

le and trailer combination will be se-
riously affected and this could result in a seri-
ous accident. » 239

● Always secure loads correctly with suitable
and undam
aged attachment rope or straps. Driving with a trailer
Adjusting the headlights
When to
w

ing a trailer, the front of the vehicle
may rise and so the dipped beam headlights
may blind other drivers. Use the headlight
range control to lower the cone of light. If you
do not have headlight range control, have
the headlights adjusted by a specialised
workshop. Vehicles with high-intensity dis-
charge lamps adapt automatically and do not
require adjustment.
Things to note when towing a trailer or cara-
van
● If the trailer has an overru
n brake, apply
the brakes gently at first and then, firmly.
This will prevent the jerking that can be
caused by the trailer wheels locking.
● As of the combined vehicle and trailer
mas
s, braking distances will be greater.
● Select a low gear before driving down a
steep hi
ll to use the engine braking effect to
slow down the vehicle. Otherwise, the brak-
ing system could overheat and fail.
● The vehicle centre of gravity and handling
chan
ge because of the trailer load and be- cause of the increased combined mass of the
vehicl

e and trailer.
● If the towing vehicle is empty and the trail-
er loaded then the lo
ad distribution is incor-
rect. If you must travel in these conditions,
drive carefully and reduce your speed accord-
ingly.
Hill starts with a trailer
Depending on the hill and the gross com-
bined weight, it is possible that the com-
bined vehicle and trailer move backwards
slightly when starting.
For a hill start with a trailer, proceed as fol-
lows:
● Press and hold the brake pedal.
● Press the button  once to turn off the
el ectric
p

arking brake ››› page 187.
● Press and hold the button  to hold the
