One of the following systems can be installed
in the vehicle:
● Heating and fresh air system
● Manual air conditioning
● Climatronic
The heatin g and fr

esh air system heats and
ventilates the interior. The heating and fresh
air system cannot cool.
The manual air conditioning and the Clima-
tronic cool and dehumidify the air. They oper-
ate most effectively with the windows and
the sunroof closed. If a great deal of heat ac-
cumulates in the interior, ventilating it can
accelerate the cooling process.

Operation
In the case of the Climatronic, the control
p anel
s
creen shows the functions that are
currently activated. WARNING
When visibility through the window display is
poor, the ri sk

of collisions and accidents
which may cause serious injury increases.
● To guarantee good visibility, keep all win-
dows
free of ice and snow and properly dem-
isted.
● Adjust the heating, air conditioning and the
heated r
ear window so that the windows do
not mist up.
● Drive off only when you have good visibility
through the windo
ws.
● Do not use the air recirculation for long pe-
riods of
time. When the cooling is switched
off and the air recirculation is on, the win-
dows can mist over very quickly and seriously
impair visibility.
● Switch the air recirculation off when you do
not need it. WARNING
Used air can quickly cause driver tiredness
and reduc e their att

ention span, which could
lead to collisions, accidents and serious in-
jury.
● Never switch off the fan for a long time or
leav
e the air recirculation on for too long, since no exterior air enters the interior during
that
time. CAUTION
If the air conditioning is not working, switch
it off immedi

ately, together with the de-
frost/demist function (in the case of manual
air conditioning) and have a specialised
workshop check it out. This may help to avoid
other possible damage. CAUTION
To avoid damaging the heated rear window,
nev er affi x

adhesives to the electric filaments
on the inside of it. Air recirculation
In air recirculation mode, no fresh air enters
the
v
ehic

le interior.
To switch on the air recirculation, turn the ad-
juster to the right  or press the  button.
To switch off the air recirculation, turn the ad-
juster to the left  or press the  button

.
● Nev

er use the air recirculation for too long,
since no e
xterior air enters the interior during
that time.
● When the cooling is switched off and the
air recir
culation is on, the windows can mist
over very quickly and seriously impair visibil-
ity.
● Switch the air recirculation off when you do
not need it. CAUTION
In vehicles with an air conditioner, do not
smoke when air r ec

irculation is switched on.
The smoke taken in could impregnate the
cooling vaporiser and the activated charcoal
cartridge of the dust and pollen filter, leading
to permanent unpleasant odours. Note
● Climatr onic:

When reverse gear is engaged,
the air recirculation switches on briefly to
prevent exhaust gas from entering the interi-
or.
● When the outside temperature is very high,
it is
recommendable to switch the air recircu-
lation on briefly to cool down the interior
faster. 130

Air vents Fig. 143
On the dash panel: air vents To achieve sufficient heating power, cooling
and
v
enti
lation in the interior, the vents
should be left open.
Key to the Fig. 143:
Adjustable air vents: the vent slats can
be used to open and close the vents and
to adjust air direction. For the air to reach
1 the windows as best as possible, open
the c
orr
e
sponding vent and turn it to the
defrost/demist position, where it will en-
gage.
Non-adjustable air vents
There are more vents in the footwell areas
and at the back of the interior. 2 CAUTION
Never place food, medicines or other temper-
atur e-

sensitive objects close to the air vents.
Food, medicines and other objects sensitive
to heat or cold may be damaged or made un-
suitable for use by the air coming from the
vents. 131

Tips and instructions for use Fig. 144
At the top of the centre console: Clima-
tronic c
ontrols The following tips and instructions for use
w
i
l

l help you to use the systems properly.
Reasons why the cooling switches off auto-
matically or will not switch on
● The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than ap-
prox
imately +3°C (+38°F).
● The cooling system compressor has been
temporari
ly 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. How to optimise visibility
●
To improve heating or cooling performance
and to prev
ent the windows from misting
over, keep the air intake slots in front of the
windscreen free of snow, ice and leaves.
● To allow the air to move freely through the
interior from the fr
ont to the rear, keep the
ventilation slits located at the back of the
luggage compartment free.
● The highest possible heating power will on-
ly be re
ached and ice removed from the win-
dows as quickly as possible when the coolant
is at its operating temperature.
Recommended settings for the heating and
fresh air system and the manual air condi-
tioning
● Switch off the air recirculation. ●
Set fan s
peed  or .
● Turn the temperature control to the inter-
mediate po
sition.
● Open and direct all the air outlets in the
dash p
anel.
● Turn the air distribution control to the re-
quired pos
ition.
● Manual air conditioning: pres
s the  but-
ton in the control panel to switch on the cool-
ing. The air is dehumidified in cooling mode.
Recommended Climatronic settings
● Press the  button in the control panel.
● Set the temperature to +22°C (+72°F).
● Open and direct the air outlets in the dash

Dust and pollen filter
The dust and pollen filter should be changed
regularly in order to maintain air conditioner
performance.
If the vehicle is used frequently in areas
where the outside air is highly polluted, it
may be necessary to change the filter before
the next scheduled service.
Water under the vehicle
If the humidity and temperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a small pool underneath the vehicle.
This is normal and does not indicate a leak! Driving

Switching off the engine while driving makes
st op

ping the vehicle difficult. As a conse-
quence you may lose control of the vehicle
and there is a risk of serious accident.
● The assisted braking and steering systems,
the airbag sys
tem, seat belts and certain
safety equipment are only active while the
engine is running.
● The engine should only be switched off
when the vehic
le is at a standstill. WARNING
While the engine is running or starting it
cou l

d help reduce the risk of serious injury.
● Never start or leave the engine running in
poorly v
entilated or closed spaces. Exhaust
gas contains carbon monoxide, a toxic, col-
ourless and odourless gas. Carbon monoxide
can cause people to lose consciousness. It
can also cause death. » 133

Driving
and increase braking distance. If you drive for
a pr o
lon
ged period on salted roads without
braking then brake carefully several times to
eliminate the layer of salt on the brakes ››› .
If the
v

ehicle remains parked for considera-
ble lengths of time, is used little, or if the
brakes are not used, there may be corrosion
on the brake discs and a build up of dirt on
the brake pads. If the brakes are not used fre-
quently, or if rust has formed on the discs,
SEAT recommends cleaning the pads and
discs by braking firmly a few times at a mod-
erately high speed. Only do this without en-
dangering vehicles behind you or any other
road users ››› .
F au
lt

s in the brake system
During braking, if you notice that the vehicle
does not react as usual (that the braking dis-
tance has increased suddenly) it may be pos-
sible that there is a fault in the braking sys-
tem. This is indicated by the warning lamp
. Take the vehicle to a specialised work-
shop immediately and have the fault re-
paired. Drive at a moderate speed and be
prepared to use more pressure on the brake
pedal, and allow for longer stopping distan-
ces.
Brake servo
The brake servo only operates when the en-
gine is running and the pressure applied by
the driver on the brake pedal increases. If the brake servo does not operate or the ve-
hicle mu

st be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate ››› .
WARNING
New brake pads do not brake to full efficien-
cy.
● For the fir

st 320 km, new brake pads have
not y
et reached their maximum braking ca-
pacity, and need to be “run in” first. For this,
to compensate for reduced braking efficiency
the brake pedal will have to be pressed with
more force.
● To avoid losing control of the vehicle and
caus
ing serious accidents, always take great
care when driving with new brake pads.
● When running in new brake pads, always
res
pect the safety distances between you and
other vehicles and do not cause situations re-
quiring extreme braking performance. WARNING
When brakes overheat, braking is less effi-
cient and br

aking distances increase.
● When driving on slopes, brakes can be
overlo
aded and overheat quickly.
● Reduce speed or change down a gear when
faced w
ith steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system. ●
Non-s t

andard or damaged front spoilers
could restrict the airflow to the brakes and
cause them to overheat. WARNING
Wet, frozen or salt-covered brakes take lon-
g er t o en

gage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
brakin
g gently several times, when visibility,
weather, and road and traffic conditions per-
mit. WARNING
Driving without the brake servo may signifi-
cantly inc

rease the braking distance and re-
sult in a severe accident.
● Never allow the vehicle to move forwards
when the engine is
switched off.
● If the brake servo does not operate or the
vehicl
e must be towed, then the brake pedal
will have to be pressed with more force given
that the braking distance will be increased
when the brake servo does not operate. CAUTION
● Never m ak

e the brakes “slip” by pressing
the pedal gently, if it is not really necessary
to brake. Continuously pressing on the brake
pedal will heat the brakes. This could signifi-
cantly reduce braking power, increase » 141

Operation
ahead as you drive and keep a safe distance
fr om the
v
ehicle in front, it is possible to slow
down by simply lifting your foot off the accel-
erator. This eliminates the need for constant
braking and acceleration.
Calm and steady driving
Constancy is more important than speed: The
more you drive at a constant speed, the lower
the fuel consumption.
When driving on the motorway, it is more effi-
cient to drive at a constant and more moder-
ate speed than to be continuously accelerat-
ing and braking. As a general rule, you will
reach your destination just as quickly when
you drive at a constant speed.
The cruise control function helps you to ach-
ieve a constant style of driving.
Moderate use of additional devices
It is important to travel in comfort, but con-
venience systems should be used ecological-
ly.
Some equipment, when connected, increase
fuel consumption considerably, for example:
● Air conditioning cooling system: If the air
conditioning sy
stem is required to cool to
significantly lower temperatures than the true
outside temperature, it will require a large
amount of energy from the engine. Therefore,
we recommend that the selected temperature for the vehicle is not too different to the out-
side temper

ature. It is a good idea to air the
vehicle before starting your journey and to
drive a short distance with the windows
open. Then you can close the windows and
switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driv-
ing with the windows open increases fuel
consumption.
● Switch off the seat heating when the seats
have w
armed up.
● Switch off the heated rear window when it
is not
moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving
for the engine to warm up and to normalise
consumption.
The engine and catalytic converter need to
reach their proper working temperature in or-
der to minimise fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 150 shows the difference in consump-
tion for the same journey at +20°C (+68°F)
and at -10°C (+14°F).
Therefore, unnecessary short journeys
should be avoided. Try to combine trips. The vehicle uses more fuel in winter than in
summer, ev

en when other conditions are the
same.
The engine takes a long time to warm up
when it is idling. In addition, mechanical
wear and pollutant emissions are also espe-
cially high during this initial warm-up phase.
It is therefore best to drive off immediately af-
ter starting the engine. Doing this avoids run-
ning the engine at a high speed.
Adjusting type pressures.
Having the correct pressure in your tyres
helps to reduce rolling resistance and, as a
result reduces fuel consumption. Increasing
the tyre pressure slightly (+0.2
bar/+3 psi/+200 kPa) can help to save fuel.
When you buy new tyres, make sure they are
optimised for minimum rolling resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils,
known as low friction engine oil, helps to re-
duce fuel consumption. These oils reduce the
resistance caused by friction in the engine,
they flow around the engine more quickly
and efficiently, particularly in cold starts. The
effect is particularly noticeable in vehicles
frequently used for short journeys.
Always check the engine oil level and ob-
serve service intervals (engine oil change in-
tervals).
150

Operation
Catalytic converter The catalytic converter permits the subse-
quent tr
e
atment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil
›››
page 189.
● Do not tow-start the vehicle; use the starter
cab l

es ›››
 page 43.
If you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. For the sake of the environment
Even when the emission control system is
work in

g perfectly, there may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel
used. Driving tips
Driv in
g abr

oad In some countries, certain safety regulations
and requir
ements

are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
● Does the vehicle need technical modifica-
tions f

or driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostic
s equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion countr
y?
● For petrol vehicles: Is unleaded petrol avail-
able at
the right octane rating?
● For diesel engines: is diesel fuel available
with a low s
ulphur content?
● Are a suitable engine oil ( ›››

page 189) and
other engine fluids complying with SEAT
specifications available in the destination
country?
● Are special tyres required in the destination
countr
y? CAUTION
SEAT does not accept liability for any damage
to the v

ehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving through flooded roadways
To prevent damage to the vehicle when driv-
ing thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded z

one. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or sw it
c

h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water.
● Disconnect the Start-Stop system whenever
cro
ssing water. WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater. 152

Operation
● If the g
e
ar is changed with the manual
gearbox.
● If the airbag is triggered. WARNING
Use of the cruise control could cause acci-
dents and sev

ere injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the dis
tance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpav
ed roads.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● To avoid unexpected operation of the cruise
contro
l system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the pr
evailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a c
onstant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Safety Assist* (City Safety As-
s
i
s

t function)
Introduction The City Safety Assist function covers driving
sit
uation

s at a distance of about 10 metres in
front of the vehicle, in a speed range of ap-
proximately 5-30 km/h (3-19 mph).
When the system detects a possible collision
with a vehicle in front, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er doe

s not react to an imminent
collision, the system can automatically brake
the vehicle in order to reduce speed faced
with a possible collision. The system can
help to reduce the consequences of an acci-
dent.
If the City Safety Assist function determines
that the driver has braked insufficiently when
faced with an imminent collision, the system
can increase the brake force in order to re-
duce speed. The system can help to reduce
the consequences of an accident. WARNING
The smart technology in the City Safety As-
si s

t system cannot change the limits imposed
by the laws of physics and by the system it-
self. The increased convenience offered by
the City Safety Assist system should never
prompt you to take risks. The driver always assumes the responsibility of braking in
time.
●
The City Safety Assist function cannot pre-
vent ac

cidents or serious injury by itself.
● The City Safety Assist system may carry out
unw
anted brake interventions in complex
driving situations e.g. when a vehicle crosses
at a short distance. WARNING
Relying on the City Safety Assist system in
c ity driv

ing as part of one's driving behaviour
may cause accidents and serious injury. The
system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● The City Safety Assist function does not re-
act to peop
le, animals or vehicles that cross
or move in the opposite direction in the same
lane.
● If after switching on the City Safety Assist
function the
vehicle begins to move, slow the
vehicle with the foot brake. CAUTION
If you suspect that the City Safety Assist la-
ser sensor i s

damaged, switch it off. This will
avoid additional damage. 156

Operation
Possible malfunction in the laser sensor
If l
a
ser sensor operation is impaired, for ex-
ample due to heavy rain, mist, snow or dirt,
the City Safety Assist system function is tem-
porarily switched off. On the instrument pan-
el display the control lamp  flashes.
When the fault in the laser sensor has been
rectified, the City Safety Assist system func-
tion automatically becomes available again.
The control lamp  switches off.
The following conditions could prevent the
City Safety Assist system from functioning:
● Tight bends.
● Accelerator pressed all the way down to the
floor.
● If the C

ity Safety Assist system is switched
off or there i
s a fault ››› page 157.
● If the laser sensor is dirty, covered or over-
heated ›

›› page 158.
● In the event of snow, heavy rain or dense
fog.
● If ther

e are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● V

ery dirty vehicles with a low degree of re-
flection.
● Pre

sence of thick dust. Hill driving assistant*
Operation This function is only included in vehicles with
ESC.
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-
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,
● 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 positions S, D or R in vehi-
cles with an automatic 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
