hand seat.
Adjusting the seat forwards and backwards
– Pull up the grip and move the seat forwards or backwards.
– Then release the grip and move the seat further until the catch engages.
Adjusting the seat height*
– Pull the lever up or push down (several times if necessary) from its home position. This adjust s the seat height in stages. Adjusting the backrest angle
– Take your weight off the backrest and turn the hand wheel.
Adjusting the lumbar support*
– Take your weight off the backrest and turn the hand wheel to adjust the lumbar support.
The backrest curvature of the cushioned area is determined by the settings
made in the lumbar region. This supports the natural curvature of the spine
very effectively.
WARNING
•Never adjust the driver or front passenger seat while the vehicle is in
motion. While adjusting your seat, you will assume an incorrect sitting
position. Risk of fatal accidents. Adjust the driver or front passenger seat
only when the vehicle is stationary.•To reduce the risk of injury to the driver and front passenger in case of
a sudden braking or an accident, never drive with the backrest tilted
towards the rear. The maximum protection of the seat belt can be achieved
only when the backrests are in an upright position and the driver and front
passenger have properly adjusted their seat belts. The further the back-
rests are tilted to the rear, the greater the risk of injury due to improper
positioning of the belt web!•Exercise caution when securing the seat height into forwards/back-
wards position. Injuries can be caused if the seat height is adjusted
without due care and attention.

Driving
172Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the foot brake to stop the vehicle.
– Apply the handbrake.
– The first gear should also be selected.
– Switch the engine off and remove the key from the ignition lock.
Turn the steering wheel slightly to engage the steering lock.
– Always take you car keys with you when you leave the vehicle ⇒ .Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.•If the vehicle is parked facing downhill, turn the front wheels so that they
point towards the kerb .•If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .•Secure the vehicle as normal by applying the handbrake firmly and
engaging first gear.WARNING
•Take measures to reduce the risk of injury when you leave your vehicle
unattended.
•Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.•Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to occupants.•Never leave children alone in the vehicle. They could set the vehicle in
motion, for example, by releasing the handbrake or the gear lever /
selector lever.•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Hill-start aid*
This function is only included in vehicles fitted with ESP.This device helps when starting uphill.
These are the basic operation conditions: doors closed, brake pedal pressed
down and vehicle in neutral. The system gets activated on engaging gear.
This system also works when reversing uphill.
After removing your foot from the brake pedal, the braking force is maintained
for a few seconds to prevent the vehicle from moving backward when put into
gear. This short space of time is enough to start the vehicle with ease.
This system also works when reversing uphill.

Trailer towing193
Safety First
Controls and equipment
Practical tips
Technical Data
Trailer towingInstructions to followYour vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. For the after-market fitting of a trailer towing bracket see
⇒ page 195.
Connectors
Your vehicle is fitted with a 12-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. This is
available in any SEAT dealer.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to
the maximum permitted trailer weight, you can then climb correspondingly
steeper slopes.
The maximum trailer weights listed are only applicable for altitudes up to
1,000 m above sea level. With increasing altitude the engine power and
therefore the vehicle's 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 reduced by 10% for
every further 1,000 m (or part 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 maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit. The figures for
trailer weights and draw bar weights 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 figures
for the towing bracket, are given in the registration documents ⇒Section
“Technical 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 permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure 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 mirrors. If this is not the case, you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
•Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.

Trailer towing
194•Find out whether special regulations apply to towing a trailer in your
country.Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•By law, the ball coupling must be re moved if a trailer is not being towed
and it obscures the number plate.Driving tipsDriving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution. Speed
The stability of the vehicle and trailer is reduced 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 especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of
snaking . Never try to stop the “snaking” by increasing 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 the trailer wheels locking. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Reheating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always monitor the temperature indicator for the
coolant ⇒page 53.
Electronic Stabilisation Program*
The ESP* system makes it easier to stabilise the trailer in case it skids or
swings.

Trailer towing
196If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle and
including the maximum resting weight.
Elevation values for securing the towing bracket:
65 mm (minimum)
350 mm to 420 mm (fully laden vehicle)
357 mm
569 mm
875 mm
1,040 mm
Fitting a towing bracket•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•Submit to the legal requirements in your country (e.g. the fitting of a sepa-
rate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and an electrical socket must be connected to the vehicle's
electrical system. The above-mentioned require specialized knowledge and
tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.WARNING
Towing brackets should be fitted by specialists.
•If the towing bracket is incorrectly installed, there is serious danger of
accident.•For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•If the electrical socket is incorrectly installed, this could cause damage to
the vehicle's electrical system.Note
For the sports model (FR, Cupra...), fitting of a trailer bracket is not recom-
mended due to the design of the bumpers.

refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.•Switch off the engine and remove the key from the ignition.•Apply the handbrake and move the gear stick to neutral or selector
lever to position P.•Keep children away from the vehicle.•Never touch hot engine parts. There is a risk of burns.•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 264. The battery could
explode.•Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!•Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.•Al wa ys m ake s u re yo u ha ve n o t l e f t a ny o bj e c t s , s u ch as cl e an i n g cl o t h s
and tools, in the engine compartment.•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!
