alid for vehicles: Without Auto Hold function
The hi
ll driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● driver door closed,
● vehicle completely stationary, ●
engine ru nnin

g and foot on the brake,
● besides having a gear engaged or being in
neutral f
or manual gear change and with the
selector lever at position S, D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If y

ou do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or u
se the hand brake immediately.
● When following a line of traffic uphill, if you
want t
o prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. Note

or the engine is switched off (for instance
when being towed), the car can still be
steered. However, more effort than normal
will be required to turn the steering wheel.

Operation
Economical and environmentally-
friendly driv
in
gFuel consumption, environmental pollution
and we
ar t

o the engine, brakes and tyres de-
pends largely on driving style. Fuel consump-
tion can be reduced by 10-15% with an eco-
nomical driving style and proper anticipation
of traffic conditions. The following section
gives you some tips on lessening the impact
on the environment and reducing your oper-
ating costs at the same time.
Active cylinder management (ACT ®
)*
Depending on vehicle equipment, the active
cylinder management (ACT ®
) may automati-
cally deactivate some of the engine cylinders
if the driving situation does not require too
much power. When it is switched off, no fuel
is injected into these cylinders, hence total
fuel consumption may be reduced. The num-
ber of active cylinders can be seen on the in-
strument panel display ›››
 page 37.
Foresight when driving
Acceleration causes the vehicle to consume
more fuel. If you think ahead when driving,
you will need to brake less and thus acceler-
ate less. Wherever possible, let the car roll
slowly to a stop, with a gear engaged (for in-
stance when you can see that the next traffic
lights are red). This takes advantage of the
engine braking effect, reducing wear on the brakes and tyres. Emissions and fuel con-
sumption w
i

ll drop to zero due to the overrun
fuel cut-off.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear. Running the engine at
high rpm in the lower gears uses an unneces-
sary amount of fuel.
Manual gearbox : shift up from first to second
gear as soon as possible. In any case, we rec-
ommend that you change to a higher gear
upon reaching 2,000 rpm. Choosing the right
gear enables fuel savings. Select the highest
possible gear appropriate for the driving sit-
uation (the engine should continue function-
ing with cyclical regularity).
Automatic gearbox : accelerate gradually and
without reaching the “kick-down” position.
Avoid driving at high speed
Avoid travelling at top speed, whenever pos-
sible. Fuel consumption, emission of harmful
gases and noise pollution multiply dispropor-
tionately as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling
is automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, at level crossings and at traffic lights that remain red for long
periods of
time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. Avoid running the engine at high
speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature in
order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres

Operation
●
The knock s
or damage on the radiator
grille, bumper, wheel arch and vehicle under-
body can adjust the orientation of the sen-
sors. This can affect the parking aid function.
Have the function checked by a specialised
workshop. Note
● In c ert

ain situations, the system can give a
warning even though there is no obstacle in
the detected area, e.g:
–with rough or cobbled floors or ground
with long grass;
– with external ultrasound sources, such as
cleaning vehicles or other vehicles;
– In downpours, intense snow or dense ex-
haust gases;
– if the registration plate (front or rear) is
not properly affixed to the bumper sur-
face;
– or in locations such as the brow of a hill.
● In order to guarantee good system opera-
tion, keep the ultr
asound sensors clean, free
of snow or ice, and do not cover them with
adhesives or other objects.
● If you use high-pressure or vapour equip-
ment to c
lean the ultrasound sensors, apply
it directly only very briefly and always from a
distance of more than 10 cm.
● Retrofitting of accessories to the vehicle,
such a
s a bicycle rack, may interfere with the
operation of the Parking Aid. ●
In order t o f

amiliarise yourself with the sys-
tem, it is advised that you practice parking in
an area or car park that is free from traffic.
There must be good weather and light condi-
tions.
● The volume and tone of the warnings can
be modified, in addition t
o the indications
››› page 241.
● In vehicles without a driv
er information
system, these parameters can be modified in
a SEAT Official Service or in a specialised
workshop.
● Please observe information on towing a
trail
er ››› page 242.
● The display on the Easy Connect screen
shows
a slight time delay. Rear parking aid*
The rear Parking Aid assists the driver in
p
ark

g by means of audible warning
sounds.
Description
There are sensors integrated in the rear
bumper. When the sensors detect an obsta-
cle, you are alerted by audible warnings.
Make particularly sure that the sensors are
not covered by adhesives, residues and the
like, as this could affect the system's opera-
tion. Cleaning instructions ››› page 259. The approximate measurement range of the
rear sen

sors is:
side area0.60 m
central area1.60 m As you approach the obstacle, the time inter-
val
betw

een the audible warnings will be re-
duced. When you reach around 0.30 m the
warning will be constant: Do not continue to
move forward (or backward) ››› in General
inform ation on p

age 237, ››› in General in-
form ation on p
age 237 !
If you maintain separation from the obstacle,
the volume of the warning begins to reduce
after four seconds (does not affect the tone
of the constant warning).
Activating/Deactivating
When engaging reverse gear, the parking aid
is automatically switched on. This is con-
firmed with a short warning.
On disengaging reverse gear, the Parking Aid
system is disconnected immediately.

Towing bracket device
Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 254.
Connectors
Your vehicle is fitted with a 13-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. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly 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 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 re- duced by 10% for every further 1000 m (or
par
t

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 maxi-
mum 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 towing bracket figures for
your specific model, which may be lower than
these figures, are given in the vehicle docu-
mentation or on ››› page 289, Technical
specifications.
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
The maximum permissible tyre pressure val-
ues are shown on the sticker on the back of
the left front door frame. Set the tyre pres-
sure 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 rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 252.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 252. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 251

●
Driving with a trailer involves an extra effort
f or the
v

ehicle. Therefore, before fitting a
towing bracket, please contact a Technical
Service to check whether your cooling system
needs modification. ●
The leg
al requirements in your country
must be observed (e.g. the fitting of a sepa-
rate control lamp).
● Certain vehicle components, e.g. the rear
bumper, mu
st be removed and reinstalled.
The towing bracket securing bolts must be
tightened using a torque wrench, and a pow-
er socket must be connected to the vehicle
electrical system. This requires specialised
knowledge and tools.
● Figures in the illustration show the eleva-
tion value and the att
achment points which
must be considered if you are retrofitting a
towing bracket. WARNING
The towing brackets should be fitted at a spe-
ci a

lised workshop.
● If the towing bracket is incorrectly instal-
led, there i
s a serious danger of accident.
● For your own safety, please observe the tow
brack
et manufacturer's instructions. CAUTION
● If the po w

er socket is incorrectly installed,
this could cause damage to the vehicle elec-
trical system. Note
● SEA T r

ecommends that the towing hooks
be fitted at a specialised workshop. Consult your SEAT dealer in case additional modifica-
tions
t

o your vehicle are necessary.
● Due to the specific design of the exhaust,
the fitting of a c
onventional towing hook is
not recommended for some sportier versions.
