The control elements in ⇒ fig. 90 are mirrored for the front right-
hand seat.
1
Adjusting the seat forwards and backwards
– Pull up the grip and move the seat forwards or backwards.
– Then release the grip 1
and move the seat further until the
catch engages.
2
Adjusting the seat height*
– Pull the lever up or push down (several times if necessary) from
its home position. This adjusts the seat height in stages. 3
Adjusting the backrest angle
– Take your weight off the backrest and turn the hand wheel.
4
Adjusting the lumbar support*
– Take your weight off the backrest and turn the hand wheel to
adjust the lumbar support.
As you make the adjustments, the curvature of the cushioned area of the
lumbar region becomes more or less acute. In this way, it adapts to the nat-
ural curvature of the spine.
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 to-
wards 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
backrests are tilted to the rear, the greater the risk of injury due to im-
proper 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 with-
out due care and attention.

tions in ⇒ page 208. 
Luggage compartment
Storing objects
All luggage must be securely stowed. Please observe the following points to ensure the vehicle handles
well at all times:
– Distribute the load as evenly as possible.
– Place heavy objects as far forward in the luggage compartment
as possible. –
Secure luggage in the luggage compartment with suitable
straps on the fastening rings.
WARNING
● Loose luggage and other loose items in the vehicle can cause serious
injuries.
● Loose objects in the luggage compartment can suddenly move and
change the way the vehicle handles.
● During sudden manoeuvres or accidents, loose objects in the passen-
ger compartment can be flung forward, injuring vehicle occupants.
● Always store objects in the luggage compartment and secure with
suitable straps. This is especially important for heavy objects.
● When you transport heavy objects, always take in account that a
change in the centre of gravity can also cause changes in vehicle han-
dling.
● Please observe information on safe driving ⇒  page 7, Safe driving.
CAUTION
Hard objects on the shelf could chafe against the wires of the heating ele-
ment in the rear window and cause damage.
Note
The ventilation slots in front of the rear side windows must not be covered
as this would prevent stale air being extracted from the vehicle. 

174Driving
–Select first gear.
– Switch the engine off and remove the key from the ignition. 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 se-
lecting first gear.
WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle 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.
● 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 with ESC (ESP).
This device helps when starting uphill.
These are the basic operation conditions: doors closed, brake pedal press-
ed 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 main-
tained for a few seconds to prevent the vehicle from moving backward when
putting into gear. This short space of time is enough to start the vehicle
with ease.
This system also works when reversing uphill.
WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the hand brake immediately.
● If the engine stalls, depress the brake pedal or use the hand brake
immediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off.
Note
The Official Service or a specialist workshop can tell you if your vehicle is
equipped with this system. 

Trailer towing
Trailer towing Instructions to follow
Your 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. If you wish to retrofit a towing bracket, consult
⇒ page 196.
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 / drawbar load
Never exceed the authorised trailer weight. If you do not load the trailer up
to the maximum permitted trailer weight, you can then climb correspond-
ingly 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'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 1000 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 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 figures for
the towing bracket, are given in the vehicle documents 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 mov-
ing.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the stick-
er 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 brack-
ets. 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 ve-
hicle is used frequently for towing a trailer.
● Find out whether special regulations apply to towing a trailer in your
country. 

196Trailer towing
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 caus-
ing injury.
Note
● By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate. 
Driving tips
Driving 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 slight-
est 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 be-
fore going down a steep downhill. This enables you to use the engine brak-
ing to slow down the vehicle.
Reheating
At very high temperatures and during prolonged slopes, driving in a low
gear and high engine speed, always monitor the coolant temperature gauge
⇒ page 55.
Electronic Stability Control*
The ESC (ESP)* system helps to stabilise the trailer in case of skidding or
rocking. 
Fitting a towing bracket*
It is possible to fit a towing bracket to the rear of the vehicle. 

569 mm
875 mm
1040 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.
● The legal requirements in your country must be observed (e.g. the fitting
of a separate 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 a power socket must be connected to the vehicle's elec-
trical system. This requires specialised 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. 

Refuelling
The fuel cap cover opens automatically with the central lock-
ing system. The tank holds approximately 55 litres.
Fig. 138 Tank flap open
Unscrewing the tank cap
– Lift the lid.
– Unscrew the cap, turning it anti-clockwise.
Closing the tank cap
– Screw the tank cap to the right, until the point of feeling a
“click”.
– Close the drawer. Make sure you hear it click into place. The
tank cap is secured with an anti-loss attachment The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are
warm.
The correct fuel grade for your vehicle is given on a sticker on the inside of
the fuel tank flap. Here you will find further information on fuel.
Releasing the fuel tank flap manually
If the central locking system fails, the fuel tank flap can be opened manually
as follows:
●
Open the tailgate
● Remove the cover from the right side trim in the luggage compartment.
● Insert a hand and pull the locking device back
● Open the cap and take out the plug. 

WARNING (Continued)
● 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.
● Always make sure you have not left any objects, such as cleaning
cloths 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 trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, 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.WARNING (Continued)
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop. 
