Driving and the environment
Avoid carrying unnecessary loads
The lighter the v
ehicle, the more economical and ecological the driving
style. For example, an additional weight of 100 kg will increase fuel con-
sumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads from the vehicle.
Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Option-
al equipment and accessories (such as roof racks or bike carriers) reduce
the aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds. 

the ignition is
sw

itched. This signals that the lamp is working properly. They
will switch off after a few seconds. WARNING
Observe traffic regulations when cleaning the diesel particulate filter
whil e driv

ing.
● Only carry on driving if visibility, weather, road and traffic conditions
so permit.
● Never end

anger your safety or that of other road users. CAUTION
Always pay attention to any lit lamps and to the corresponding descriptions
and ins truction

s to avoid damage to the vehicle. Note
While the control lamps ,  or  r
emain lit, there may be engine prob-
lems, fuel consumption may be greater and the engine may lose power. Catalytic converter The catalytic converter permits the subsequent treatment of the exhaust
ga
se

s thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
● Always use unleaded petrol.
● Never run the tank completely dry.
● Do not top up with too much engine oil ⇒ page 279.
● Do not

tow-start the vehicle; use the starter cables ⇒ page 337.
If

you should notice misfiring, uneven running or loss of power when the car
is moving, reduce speed immediately. Have the car inspected by a Technical
Service. If this happens, unburnt fuel can enter the exhaust system and es-
cape into the atmosphere. The catalytic converter can also be damaged by
overheating. For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of

sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel being used. 
Diesel particulate filter The diesel particulate filter removes soot particulates from the exhaust gas.
The filt
er r

etains these particulates and burns them. To assist the combus-
tion process, SEAT recommends you avoid frequent short trips.
● Always use diesel with a low sulphur content ⇒ page 267.
● Nev

er use petrol or fuel oil.
● Never use biodiesel. However, a blend prepared by the diesel manufac-
turer c
ontaining biodiesel within the limits established by the EN 590
standard may be used ⇒ page 267. Safety First Operating instructions Practical tips Technical Data

Trailer towing WARNING (Continued)
● Trailers with a high centre of gravity can overturn more easily than
tr ai
lers with a low centre of gravity.
● Avoid brusque manoeuvres and sudden braking.
● Always take the following precautions seriously.
● Reduce your speed immediately if you observe the trailer rocking
from side t
o side.
● Never drive at more than 80 km an hour when towing a trailer (or 100
km an hour in exc
eptional circumstances). This also applies in countries
where higher speeds are permitted. Always take the speed limits for ve-
hicles with and without trailers in each country into account.
● Never try to stop the “snaking” by increasing speed. WARNING
When driving with a trailer and using a trailer hitch that was not installed
by

SEAT, the Start-Stop function must be manually deactivated. Other-
wise, this could cause a braking anomaly that could result in an accident
with serious consequences.
● Always manually deactivate the Start-Stop function when a trailer is
being used on a tr
ailer hitch that has not been installed by SEAT. Note
● Always turn off the anti-theft alarm system before connecting or discon-
nectin g a tr

ailer ⇒ page 78. Otherwise, the tilt sensor may erroneously acti-
vate the alarm.
● Never use a trailer with a new engine (for the first 1000 km or 600 miles)
⇒ p
age 257. ●
At SEAT, we recommend folding in the trailer hitch ball when a trailer is
not bein
g used. In case of a rear collision, the damage caused to the vehicle
with the extended trailer hitch ball could be more extensive.
● In some models, a trailer hitch is necessary for towing vehicles. For this
rea

son, you should store the tow hitch in the vehicle at all times. 

233
Trailer towing
Driving with a trailer Tec hnic
al requirements If the car is supplied with a
factor
y-fitted tow hitch it will already have the
necessary technical modifications and meet the statutory requirements for
towing a trailer.
Only use an approved trailer 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 in-
structions. Never fit a trailer tow hitch “that distributes the load” or “balan-
ces the load”.
Bumper mounted tow hitch
Never fit a tow 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. Regularly 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 re-
quirements. The trailer braking system should never be connected to the ve-
hicle braking system.
Trailer cable
Always use a cable between the vehicle and the trailer ⇒ page 235.Trailer rear lights
The rear lights

of a trailer must fulfil the corresponding standards
⇒ page 235.
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 spe-
cialist workshop. SEAT recommends visiting a Technical Service.
Wing mirrors
When the field of vision behind the trailer cannot be seen using the stand-
ard wing mirrors of the towing vehicle, additional wing mirrors are required
according to the legal requirements of each country. The wing mirrors must
be fitted before driving and must provide a sufficient field of vision behind.
Trailer electricity consumption
Never exceed the specifications: Electrical consumer Maximum power
Position lights and rear lights 50 Watts
Indicator (each side) 54 Watts
Brake lights (total) 84 Watts
Reversing lights (total) 42 Watts
Rear fog light 42 Watts
WARNING
If the tow hitch is badly fitted or unsuitable, the trailer may separate from
the v ehic

le causing an accident with serious consequences. Safety First Operating instructions Practical tips Technical Data

Trailer towing CAUTION
● If the rear lights of the trailer are not correctly connected, the vehicle
el ectr
onics may be damaged.
● If the trailer absorbs excessive electric current, the vehicle electronics
may
be damaged.
● Never connect the trailer's electric system to the electrical connections
of the re
ar lights or any other power sources. Only use suitable connections
for providing electric current to the trailer. Note
● Towing a trailer places additional demands on the vehicle. At SEAT, we
r ec

ommend additional services between the normal inspection intervals if
the vehicle is used frequently for towing a trailer.
● In some countries, an additional fire extinguisher is required if the trailer

Trailer towing
Trailer electric socket
The electric c
onnection between vehicle and trailer is a 13-pin socket. If the
trailer plug has seven pins, an adapter cable must be used.
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 maximum power
⇒ page 233.
Trailer connected to the antitheft alarm:
● When a vehicle comes from the factory fitted with an antitheft alarm and
tow hit
ch.
● When the trailer is connected to the vehicle using the socket.
● When the vehicle and trailer electrical systems work correctly and are
not dam
aged.
● When the vehicle is locked using the vehicle key and the antitheft alarm
is t

urned on.
When the vehicle is locked, the alarm is triggered when the electrical con-
nection between the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system before connecting or disconnect-
ing a trailer. Otherwise, the tilt sensor may erroneously activate the alarm. WARNING
Erroneous or unsuitable connection of electric cables may supply energy
to the tr ai

ler causing an anomaly in the vehicle electronics that could re-
sult in an accident with serious consequences.
● All work on the electrical system must be carried out only by a spe-
cia

list workshop.
● Never connect the trailer's electric system to the electrical connec-
tions of
the rear lights or any other power sources. CAUTION
Do not leave the trailer connected to the vehicle when parked; places on its
sup por

t 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 case of a fault in the vehicle or trailer electrical system or in case of
pr o

blems with the antitheft alarm system, have the system checked by a
specialist workshop.
● If the trailer accessories use energy from the socket when the engine is
stop
ped, the battery will be discharged.
● For technical reasons, trailers fitted with rear LED lights cannot be con-
nected to the antithef
t alarm system.
● If the vehicle battery is running low, the electrical connection with the
trail
er is automatically cut.
● With the engine running, the electrical equipment on the trailer will con-
sume pow
er. 
Loading the trailer Trailer weight / drawbar load
The trai
l

er weight is the load that the vehicle can pull ⇒  . The drawbar
loa d i

s the vertical weight of the trailer hitch on the tow hitch ball
⇒  page 240.
The figures for trailer weights and draw bar weights given on the data plate
of the towing bracket 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 registration documents. The instructions in the offi-
cial vehicle documents take precedence. 

237
Trailer towing
For the sake of road safety, SEAT recommends using the maximum allowed
dra wb
ar 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 capacity.
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 rear of the
trailer:
● Distribute loads in the trailer so that heavy objects are as near to the
axle a
s possible or even above it.
● Correctly secure the trailer load.
Tyr

e pressure
Inflate the trailer tyres according to the manufacturer's instructions.
Inflate the towing vehicles tyres to the maximum ⇒ page 293.WARNING
Exceeding the maximum authorised axle load, drawbar load or the gross
comb in

ation weight of the towing vehicle and trailer could cause a seri-
ous accident with severe consequences.
● Never exceed the specifications.
● With the actual load on the front and rear axles, the maximum axle
load shou
ld 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 vehicle and trailer com-
bin ation w

ill be seriously affected and this could result in a serious acci-
dent.
● Always correctly load the trailer.
● Always secure loads correctly with suitable and undamaged attach-
ment rope or s
traps. 
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 qualified dealership. Vehicles with high-intensity
discharge lamps adapt automatically and do not require adjustment.
Details of driving with a trailer
● 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 mass, braking distances will be
great
er.
● Select a low gear before driving down a steep hill to use the engine
brakin
g effect to slow down the vehicle. Otherwise, the braking system
could overheat and fail. Safety First Operating instructions Practical tips Technical Data

238
Trailer towing
●The vehicle centre of gravity and handling change because of the trailer
lo a
d and because of the increased combined mass of the vehicle and trail-
er.
● If the towing vehicle is empty and the trailer loaded then the load distri-
bution is
incorrect. If you must travel in these conditions, drive carefully and
reduce your speed accordingly.
Hill starts with a trailer
Depending on the hill and the gross combined weight, it is possible that the
combined vehicle and trailer move backwards slightly when starting.
For a hill start with a trailer, proceed as follows:
● Press and hold the brake pedal.
● Press the button  once to turn off the electric parking brake
⇒ p ag

e 183.
● Press and hold the button  to hold the vehicle and trailer combination
us in

g the parking brake.
● With a manual gearbox: press the clutch pedal to the floor.
● Engage first gear or the gear range D ⇒ page 174, Ch
anging gear.
● Release the brake pedal.
● Move off slowly. To do this, gently release the clutch pedal (for manual
gearbo
x).
● Release the button  only when the engine provides sufficient power
to mo v

e the vehicle and trailer combination. WARNING
Jerking the trailer in an unsuitable manner could cause loss of vehicle
contr o

l with the subsequent serious consequences.
● Driving with a trailer and transporting heavy or a large objects will
chan
ge the vehicle handling and braking distances. WARNING (Continued)
● Antic ipate traffic and be extremely cautious. Brake early.
● Adju
s

t your speed and driving style to visibility, road, traffic and
weather c
onditions. Reduce your speed, especially on steep hills.
● Accelerate gently and carefully. Avoid brusque manoeuvres and sud-
den brakin
g.
● Always take the following precautions seriously. Reduce your speed
immediately
if you observe the trailer rocking from side to side.
● Never try to stop the “snaking” by increasing speed.
● Always take the speed limits for vehicles with and without trailers in
each c
ountry into account. 
Stabilising the vehicle and trailer combination Stabilisation of the vehicle and trailer combination is an extension of the
electr
onic

stability control ESC (ESP) and helps, with the assistance of the
trajectory control, to reduce trailer “snaking”.
Stabilisation of the vehicle and trailer combination is active when the ESC
(ESP)  indicator on the dashboard remains lit for about two seconds more
than the ABS indicator.
Requirements for stabilising the vehicle/trailer combination
● An original tow hitch is fitted by the manufacturer or a compatible model
is r

etrofitted.
● The ESC (ESP) is on. The warning indicator in the control panel  is not
lit

.
● The trailer is connected to the vehicle using the socket.
● The vehicle is driven faster than 60 km/h.
● The maximum drawbar load is used. 
