Note
Always read the assembly instructions that
come w ith the c
rossbars and the roof carrier
system carefully and keep them in the vehi-
cle. Loading the roof carrier system
The load can only be secured if the crossbars
and the roof
c

arrier system are properly in-
stalled ››› .
Max imum authori

sed roof load
The maximum permissible roof load is 75 kg.
This figure comes from the combined weight
of the roof carrier, the cross bars and the load
itself on the roof ››› .
A lw
a

ys check the weight of the roof carrier
system, the cross bars and the weight of the
load to be transported and weigh them if
necessary. Never exceed the maximum au-
thorised roof load.
If you are using cross bars and a roof carrier
with a lower weight rating, you will not be
able to carry the maximum authorised roof
load. In this case, do not exceed the maxi-
mum weight limit for the roof carrier which is
listed in the fitting instructions. Distributing a load
Distrib

ute loads uniformly and secure them
correctly ››› .
Chec k
att

achments
Once the cross bars and roof carrier system
have been installed, check the bolted con-
nections and attachments after a short jour-
ney and subsequently with a certain frequen-
cy. WARNING
Exceeding the maximum authorised roof load
can r e

sult in accidents and considerable vehi-
cle damage.
● Never exceed the maximum authorised
load on the r
oof and on the axles or the vehi-
cle's maximum authorised weight.
● Never exceed the load capacity of the cross
bars
and the roof carrier system, even if the
maximum authorised roof load has not been
reached.
● Secure heavy items as far forward as possi-
ble and di
stribute the vehicle load uniformly. WARNING
If the load is loose or not secured, it could fall
from the r oof

carrier system or cause acci-
dents and injuries.
● Always use belts or retaining straps that
are suit
able and in a good condition.
● Secure the load properly. Air conditioning

Viewing Climatronic information
On the screen of Climatronic control unit and
on the screen of the factory-fitted Easy Con-
nect system, the theoretical values of the
temperature zones are shown.
The unit of temperature measurement can be
changed in the Easy Connect system.
Dust and pollen filter
The dust and pollen filter with its activated
charcoal cartridge serves as a barrier against
impurities in the air taken into the vehicle in-
terior.
The dust and pollen filter must be changed
regularly so that air conditioner performance
is not adversely affected.
If the filter loses efficiency prematurely due
to use in areas with very high levels of air
pollution, the filter must be changed more
frequently than stated in the Service Sched-
ule. »

Operation
WARNING
Reduced visibility through the windows in-
cr e
ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● The maximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Swit c

h the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. SEAT rec-
ommends visiting a SEAT Official Service. Note
● When the coo lin

g system is turned off, air
coming from the outside will not be dried. To
prevent fogging of the windows, SEAT recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the button  . The button lamp should light up.
● The maximum heat output required to de-
fro s

t windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over. Adjust using the Easy Connect sys-

The interior cooling system only works when
the engine i
s

running and fan is switched on.
The air conditioner operates most effectively
with the windows and the panoramic sliding
sunroof closed. However, if the vehicle has
heated up after standing in the sun for some
time, the air inside can be cooled more quick-
ly by opening the windows and the panoram-
ic sliding sunroof briefly.

The cooling system cannot be activated
If the air conditioning system cannot be
switched on, this may be caused by the fol-
lowing: ● The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than ap-
pro x

imately +3°C (+38°F). »

temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special Characteristics
If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air c onditioner c

ould mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air outlets


Manual recirculation
Air recirculation mode prevents the ambient
air from ent
erin

g the interior.
When the outside temperature is very high,
selecting manual air recirculation mode for a
short period refreshes the vehicle interior
more quickly.
For safety reasons, air recirculation mode is
switched off when the button  is press-
ed or the air distributor turned to .
Switching the manual air recirculation mode

To switch system on: press the  button un-
til the warning lamp lights up.
To switch system off: press the  button un-
til the warning lamp goes off.
Functioning mode of automatic air recircula-
tion (air conditioning menu)
With the automatic air recirculation mode ac-
tivated, the entry of fresh air into the cabin
interior is enabled. If the system detects a
high concentration of hazardous substances
in the ambient air, air recirculation mode is
switched on automatically. When the level of impurities drops to within a normal range, re-
cir
c

ulation mode is switched off.
The system is unable to detect unpleasant
smells.
The air recirculation will not connect auto-
matically in versions without humidity sensor
and in the following external conditions:
● The outside temperature is lower than +3°C
(+38°F).
● The cooling system is switched off and the
outside temper
ature is below +10°C (+50°F).
● The cooling system is switched off, the out-
side temper
ature is below +15°C (+59°F) and
the windscreen wipers are switched on.
Activation/deactivation of automatic air recir-
culation is done in the air conditioner menu,
under Configuration. WARNING
Observe the safety warnings ›››
in Intro-
duction on pag e 160

WARNING
You should switch on the ESC Sport mode on-
ly if the tr

affic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
● With ESC in Sport mode, the stabilising
function w
ill be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could “skid”. ●
If the E SC/ASR i

s deactivated, the vehicle
stabilisation function is not available. Note
If the ASR is disconnected or the ESC’s Sport
mode i s sel

ected, cruise control* will be
switched off. Brakes
New brake pads
F
or the fir
s

t 400 km (250 miles), new brake
pads have not yet reached their maximum
braking capacity, and need to be “run in”
first. However, you can compensate for the
slightly reduced braking effect by applying
more pressure on the brake pedal. Avoid
overloading the brakes while running them
in.
Wear
The rate of wear on the brake pads depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is
a particular problem in urban traffic and
short stretches, or with very sporty driving.
Depending on the speed, the braking force
and the environmental conditions (for exam-
ple, the temperature, air humidity, etc.)
noises may be produced on braking. Wet roads or road salt
In cert

ain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac-
tion could be delayed if the discs and pads
are damp, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
At high speed and with the windscreen wip-
ers activated, the brake pads will briefly
touch the brake discs. This takes place, al-
though unnoticeable to the driver, at regular
intervals to improve the response time of the
brakes when they are wet.
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. The layer of salt that accumulates on the
discs and pads can be removed by gently ap-
plying the brakes a few times.
Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if
rust has formed on the disks, it is advisable
to clean off the pads and disks by braking
firmly a few times at a moderately high speed

Operation
Fault in the brake system
If the br
ak
e pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately
to the nearest specialised workshop and
have the fault repaired. Drive there slowly
and remember that you will have to apply
more pressure on the brake pedal and allow
for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● App ly

the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the en
gine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. CAUTION
● Never l et

the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is
advisable to reduce speed and select a
lower gear. This makes use of engine braking
and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the br ak

e servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories s
uch as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Hill driving assistant*
This function is only included in vehicles with
E
SC.
The hi l

l 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-
prox

imately 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,
● doors closed,
● vehicle completely stationary,
● engine running 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.182

Operation
If the selector lever is placed in position R
durin g the s
t
opping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R. Note
● You c an c

ontrol whether the engine should
switch off or not by reducing or increasing the
brake force applied. While the vehicle re-
mains stopped, the engine will not stop if the
brake pedal is slightly pressed, in traffic jams
with frequent stopping and starting for exam-
ple. As soon as strong pressure is applied to
the brake pedal, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes

fr
equently
f

or different reasons. The engine does not switch off
Befor

e the stopping phase, the system veri-
fies whether certain conditions are met. The
engine does not switch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required t
emperature for the Start-Stop
mode.
● The interior temperature selected for the air
conditioner ha
s not yet been reached.
● The interior temperature is very high/low.

● The steering wheel is overly turned or is be-
ing turned.
● If

there is a danger of misting.
● After engaging reverse gear.
● In case of a very steep gradient.
● In the CUPRA version with automatic gear-
box, when it i

formation system* shows, . The engine starts by itself
During a s

topping phase the normal Start-
Stop mode can be interrupted in the follow-
ing situations: The engine restarts by itself
without involvement from the driver.
● The interior temperature differs from the

In vehicles with an automatic gearbox, if the
select or l

ever is placed in position D, N or S
after engaging reverse gear, the vehicle must
be driven at a speed faster than 10 km/h (5
mph) for the system to return to conditions in
which the engine can be stopped. 184
