234Driving and the environment
●Never run the tank completely dry.
● Do not top up with too much engine oil ⇒ page 283.
● Do not tow-start the vehicle; use the starter cables ⇒ page 341.
In order to reduce blocking of the diesel particulate filter, some vehicles
with an automatic gearbox may increase the engine speed slightly to auto-
matically start cleaning the diesel particulate filter. The warning lamp will
not light up in this case .
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. 

Trailer towing
Trailer towing Introduction
Always be aware of the legal requirements for each country to drive with a
trailer and to use a trailer bracket.
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 equip-
ment. The additional load has an effect on the useful life, fuel consumption
and the vehicle performance and, in some cases, reduce the service inter-
vals.
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 exerted by the trailer drawbar on the
ball joint of the tow hitch must not exceed 100 kg (approximately 220 lbs).
Vehicles with the Start-Stop function
With a SEAT factory fitted or retrofitted trailer bracket, the Start-Stop func-
tion is automatically deactivated when a trailer is connected. For trailer
brackets not installed by SEAT, the Start-Stop function must be deactivated
manually using a button located on the dashboard before driving with a
trailer and it must remain off for the entire journey ⇒ 
.

WARNING
Never transport people in a trailer: this will endanger in their life and is
against the law.
WARNING
The incorrect use of the tow hitch can cause accidents and injury.
● Only use a tow hitch in good condition and correctly installed.
● Never change or repair a tow hitch.
● To reduce the risk of injury in case of a reversing 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 distributes 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 large objects can affect
vehicle handling and even cause an accident.
● Always secure loads correctly with suitable and undamaged attach-
ment rope or straps.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions. 
Safety FirstOperating instructionsPractical tipsTechnical Specifications

236Trailer towing
WARNING (Continued)
● Trailers with a high centre of gravity can overturn more easily than
trailers 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 to side.
● Never drive at more than 80 km an hour when towing a trailer (or 100
km an hour in exceptional 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 trailer hitch that has not been installed by SEAT.
Note
● Always turn off the anti-theft alarm system before connecting or discon-
necting a trailer ⇒ 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)
⇒ page 261. ●
At SEAT, we recommend folding in the trailer hitch ball when a trailer is
not being 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
reason, you should store the tow hitch in the vehicle at all times. 

Trailer towing
Driving with a trailer Technical requirements
If the car is supplied with a factory-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 239.Trailer rear lights
The rear lights of a trailer must fulfil the corresponding standards
⇒ page 239.
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-
cialised 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 consumerMaximum powerPosition lights and rear lights50 WattsIndicator (each side)54 WattsBrake lights (total)84 WattsReversing lights (total)42 WattsRear fog light42 Watts
WARNING
If the tow hitch is badly fitted or unsuitable, the trailer may separate from
the vehicle causing an accident with serious consequences. 

238Trailer towing
CAUTION
● If the rear lights of the trailer are not correctly connected, the vehicle
electronics 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 rear 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
recommend 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
weight is more than 2500 kg 

WARNING
The incorrect use of the tow hitch can cause accidents and injury.
● Ensure that no person, animal or object gets in the way of the tow
ball.
● Never push the button when there is a trailer hitched or when any
kind of carrier or accessory is fitted to the tow hitch ball.
● While the ball is moving, do not interfere with any tool.
● Do not drive with a trailer if the indicator does not light.
● If there is a fault in the electric system or the trailer tow hitch, visit a
specialised workshop to have it checked.
● If the diameter of the tow hitch is less than 49 mm, never use this for
a trailer.
CAUTION
● If anything is attached to the tow hitch ball, do not, under any circum-
stances press the button.
● Never direct a high-pressure or steam cleaning system directly at the
tow hitch ball or trailer power socket. This could cause damage to seals or
remove lubricating grease.
Note
In extremely low temperatures, it is possible that the tow hitch is not re-
leased. In this case, place the vehicle in a warmer location (for example, a
garage). Installing a bicycle carrier to the tow hitch
The maximum load permitted for a bicycle carrier on the tow hitch ball is
75 kg, with a maximum distance of 300 mm from the support. The distance
between supports is the distance between the bicycle carrier centre of gravi-
ty (with the bicycles) and the centre of point of the tow hitch ball.
WARNING
The incorrect use of the tow hitch with a bicycle carrier installed can
cause accidents and injury.
● Never exceed the load and distances between supports indicated.
● Never fit the bicycle carrier to the tow hitch ball neck, underneath the
tow hitch given that the bicycle carrier may be incorrectly fitted due to
the shape of the tow hitch and the model of bicycle carrier.
● Always read and take the manufacturer assembly instructions into ac-
count.
CAUTION
Exceeding the maximum load and distance between supports indicated can
cause considerable damage to the vehicle.
● Never exceed the specifications. 
Hitching and connecting the trailer
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. 
Safety FirstOperating instructionsPractical tipsTechnical Specifications

240Trailer towing
Trailer electric socket
The electric connection 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 237.
Trailer connected to the anti-theft alarm:
● When a vehicle comes from the factory fitted with an anti-theft alarm
and tow hitch.
● When the trailer is connected to the vehicle using the socket.
● When the vehicle and trailer electrical systems work correctly and are
not damaged.
● When the vehicle is locked using the vehicle key and the anti-theft alarm
is turned 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 trailer 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 speci-
alised 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
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 case of a fault in the vehicle or trailer electrical system or in case of
problems with the anti-theft alarm system, have the system checked by a
specialised workshop.
● If the trailer accessories use energy from the socket when the engine is
stopped, the battery will be discharged.
● For technical reasons, trailers fitted with rear LED lights cannot be con-
nected to the anti-theft alarm system.
● If the vehicle battery is running low, the electrical connection with the
trailer is automatically cut.
● With the engine running, the electrical equipment on the trailer will con-
sume power. 
Loading the trailer
Trailer weight / drawbar load
The trailer weight is the load that the vehicle can pull ⇒ . The drawbar
load is the vertical weight of the trailer hitch on the tow hitch ball
⇒  page 244.
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. 

241
Trailer towing
For the sake of road safety, SEAT recommends 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 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 as possible or even above it.
● Correctly secure the trailer load.
Tyre pressure
Inflate the trailer tyres according to the manufacturer's instructions.
Inflate the towing vehicles tyres to the maximum ⇒ page 297.
WARNING
Exceeding the maximum authorised axle load, drawbar load or the gross
combination 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 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 vehicle and trailer com-
bination will 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 straps.

Driving with a trailer
Adjusting the headlights
When towing 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 overrun 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
greater.
● Select a low gear before driving down a steep hill to use the engine
braking effect to slow down the vehicle. Otherwise, the braking system
could overheat and fail. 
Safety FirstOperating instructionsPractical tipsTechnical Specifications

242Trailer towing
●The vehicle centre of gravity and handling change because of the trailer
load 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
⇒ page 185.
● Press and hold the button 
to hold the vehicle and trailer combination
using the parking brake.
● With a manual gearbox: press the clutch pedal to the floor.
● Engage first gear or the gear range D ⇒ page 176, Changing gear.
● Release the brake pedal.
● Move off slowly. To do this, gently release the clutch pedal (for manual
gearbox).
● Release the button 
only when the engine provides sufficient power
to move the vehicle and trailer combination.
WARNING
Jerking the trailer in an unsuitable manner could cause loss of vehicle
control with the subsequent serious consequences.
● Driving with a trailer and transporting heavy or a large objects will
change the vehicle handling and braking distances.
WARNING (Continued)
● Anticipate traffic and be extremely cautious. Brake early.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions. Reduce your speed, especially on steep hills.
● Accelerate gently and carefully. Avoid brusque manoeuvres and sud-
den braking.
● 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 country into account.

Stabilising the vehicle and trailer combination
Stabilisation of the vehicle and trailer combination is an extension of the
electronic stability control (ESC) and helps, with the assistance of the trajec-
tory control, to reduce trailer “snaking”.
Stabilisation of the vehicle and trailer combination is active when the ESC 
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 retrofitted.
● The ECS is switched 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. 

243
Trailer towing
● The trailer must have a fixed drawbar.
● Trailers with brakes must be equipped with a mechanical inertia brake.
WARNING
Do not let the extra safety afforded by the stabilisation system tempt you
into taking any risks when driving.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
● If the road surface is slippery, take care when accelerating.
● When a system is operating, lift your foot off the accelerator.
WARNING
It is possible that the combination stabilisation system does not correct-
ly recognised all driving situations.
● It is possible that the stabilisation system does not detect snaking of
a light trailer and thus does not intervene.
● When driving on slippery ground, the trailer could jack-knife despite
the stabilisation system.
● Trailers with a high centre of gravity may even tip over before they
start to rock sideways.
● If a trailer is not used at the trailer socket is connected (for example,
installation of a bicycle carrier with lights), repeated automatic braking
may occur in extreme driving conditions.
 Retrofitting a tow hitch
Fig. 159 Measurements and attachments to retrofit a tow hitch.
SEAT recommends visiting a specialised workshop to retrofit a tow hitch. For
example, it may be necessary to adjust the cooling system or to include
thermal plates. SEAT recommends visiting a Technical Service.
In any case, the separation distances must be observed when fitting a tow
hitch. The distance between the centre of the tow hitch ball and the road
surface ⇒ fig. 159 D
must never be lower than that indicated. This also ap-
plies when the vehicle is fully laden, including maximum drawbar load.
