instructions
Temperature
The desired temperature for the interior can-
not be lower than that of the exterior air tem- perature, as the heating and fresh air system
cannot cool or dehumidify the air.

User instructions for the air
conditioner* The interior cooling system only works when
the engine is running and the fan is switched
on.
The air conditioning operates most effective-
ly with the windows closed. However, if the
vehicle has heated up after standing in thesun for some time, the air inside can be
cooled more quickly by opening the windows
briefly.
Setting for conditions of optimal visibility
When the air conditioning is switched on, the
temperature and the air humidity in the vehi-
cle interior drop. In this way, when the out-
side air humidity is high, the windows do not
mist over and comfort for the vehicle occu-
pants is improved.
● Disable air recirculation mode

● Set the f

an to the required setting.
● Turn the temperature control to the centre
position.
● Open and direct the air outlets in the dash
panel ››› page 83.
● Turn the air di

stribution control to the de-
frost position.

Air conditioning
● Press the A/C button to switch it on. The in-
dicator on the button will light up.
The cooling system does not switch on
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-
proximately +2 °C (+36 °F).
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop.
Things to note
If the humidity and temperature outside the
vehicle are high, condensation
can drip off the ev aporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting it, any residual humidity in the
air conditioner could mist over the wind-
screen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents

Operation
The rate of wear of the brake pads
depend
s
t
o a great extent on the conditions in which
the vehicle is used and the way the vehicle is
driven. If the vehicle is used frequently in city
traffic or for short trips or driven sport style,
visit a specialised workshop regularly, more
frequently than advised in the Maintenance
Programme, to have the brake pads checked.
If you drive with wet brakes, for example, af-
ter crossing areas of water, in heavy rainfall
or even after washing the car, the effect of
the brakes is lessened as the brake discs are
wet or even frozen (in winter). At higher
speed, “dry” the brakes as quickly as possi-
ble by braking gently several times. Only do
this without endangering vehicles behind
you or any other road users ››› .
A layer of salt on the discs and brake pads
w i

ll reduce the effectiveness of the brakes
and increase braking distance. If you drive for
a prolonged period on salted roads without
braking then brake carefully several times to
eliminate the layer of salt on the brakes ››› .
If the vehicle 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
››› .
Faults 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 immedi at

ely 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 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 ››› .
WARNING
New brake pads do not brake to full efficien-
cy.
● For the first 320 km, new brake pads have
not yet 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
causing serious accidents, always take great
care when driving with new brake pads.
● When running in new brake pads, always
respect 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 braking distances increase.
● When driving on slopes, brakes can be
overloaded and overheat quickly.
● Reduce speed or change down a gear when
faced with steep and long slopes. This allows
you to use the engine braking effect and to
reduce the strain on the brake system.
● Non-standard 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-
ger to engage and this increases braking dis-
tances.
● Test the brakes carefully.
● Dry the brakes, free them of ice and salt by
braking gently several times, when visibility, 92

Operation
(25 mph) in fourth gear and at 50 km/h
(31 mph) in fifth gear.
In addition, “skipping” gears when shifting
up helps to save fuel, weather and traffic
conditions permitting.
Do not wait until the last moment before
changing gear. Only use first gear when you
move off and change to second gear quickly.
Avoid the kick-down function in vehicles with
automatic gearbox.
Vehicles with a gear display help to achieve
an economical driving style as the display in-
dicates the best moment to change gear.
Let the vehicle roll
If you take your foot off the accelerator, the
fuel supply is stopped and consumption is
reduced.
Allow the vehicle to roll without accelerating,
for example when approaching a red traffic
light. However, if the vehicle is rolling too
slowly or the distance is too long, the clutch
pedal should be pressed to declutch. The en-
gine will then operate at idle speed.
If the vehicle is going to be at a standstill for
a period of time, switch off the engine; for ex-
ample, while waiting at a level crossing.
Think ahead and “flow” with the traffic
Frequent acceleration and braking considera-
bly increase fuel consumption. If you think ahead as you drive and keep a safe distance
from the vehicle 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 system 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 temperature. 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 warmed 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 t o minimi
se fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 84
shows the difference in consumption
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.

CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle. Note
While the control lamps  or
 maintain lit
up, the engine will present faults, a higher consumption of fuel and a loss of engine
power.
Catalytic converter
The catalytic converter permits the subse-
quent treatment 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 146 .
● Do not t

ow-start the vehicle; use the starter
cables ››› page 181.
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
working perfectly, there may be a smell of
sulphur under certain conditions. This de- pends on the sulphur content of the fuel
used.
Driving abroad
In some countries, certain safety regulations
and requirements 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 for driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostics equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion country?
● For petrol vehicles: Is unleaded petrol avail-
able at the right octane rating?
● For diesel engines: is diesel fuel available
with a low sulphur content?
● Are a suitable engine oil ( ››› page 146) and
other engine fluids complying with SEAT
specifications available in the destination
country?

Driver assistance systems
system is not a replacement for driver aware-
ness.
●
Always adapt your speed and the distance
to the vehicles 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 people, 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 ra-
dar feature is damaged, switch it off. This will
avoid additional damage.
● Any repair of the radar sensor requires spe-
cialist knowledge. SEAT recommends taking
your car in for technical service. Note
● If the City Safety Assist function activates a
brake, the brake pedal range is reduced. This
makes the brake pedal seem “harder”.
● Automatic brake intervention by the City
Safety Assist function can be cancelled by
pressing the clutch pedal, the accelerator
pedal or by a corrective intervention.
● During automatic braking by the City Safety
Assist function you may hear unusual noises. This is normal and is produced in the brake
system.

Operation
Safety

Operation
The City Safety Assist function is limited by
the laws of physics and by the nature of the
system itself. For this reason, this may pro-
duce reactions from the City Safety Assist
system in certain circumstances that are late
or unexpected by the driver. For this reason,
always pay due attention and if necessary, in-
tervene.
For example, the following driving situations
require special attention:
Driving through a bend
When entering or leaving a “long” bend, the
vehicle may decelerate when the radar sen-
sor detects a vehicle travelling in the adjoin-
ing lane ››› Fig. 91
A. To interrupt deceleration
you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The radar sensor will only detect narrow vehi-
cles in front if they are in the sensor detec-
tion zone ››› Fig. 91 B. This applies especially
to n

arrow vehicles such as motorbikes.
Other vehicles changing lanes
Vehicles moving into your lane in close prox-
imity can cause unexpected braking from the
City Safety Assist system ›››
Fig. 92. To inter-
rupt dec

eleration you can accelerate, turn the
steering wheel or press the clutch. Malfunction in the radar sensor
If the radar sensor operation is impaired, for
example 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 fau

lt in the radar sensor has been
rectified, the City Safety Assist system func-
tion automatically becomes available. 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 City Safety Assist system is switched
off or there is a fault ››› page 111.
● If the radar sensor is dirty, covered or over-
heated ››› page 112.
● In the event

of snow, heavy rain or dense
fog.
● If there are vehicles in front.
● Vehicles changing lanes.
● Vehicles moving in the opposite direction
in the same lane.
● Very dirty vehicles with a low degree of re-
flection.
● Presence of thick dust. Hill driving assistant*
Operation This function is only included in vehicles with
ESC.
The hill 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 for 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.

Advice
●
All repairs and modifications to the vehicle
should only be performed by a specialised
workshop. Repair and faults in the airbag system
When performing repairs and technical mod-
ifications, SEAT's directives must be ob-
served!
››› Modifications and repairs to the front bump-
er, doors, front seats, and repairs to the roof
or chassis should only be carried out in a
specialised workshop. These components
may contain parts or sensors belonging to
the airbag system.
If work is carried out on the airbag system or
parts have to be removed and fitted on the
system when performing other repair work,
parts of the airbag system may be damaged.
The consequence may be that, in the event of
an accident, the airbag inflates incorrectly or
does not inflate at all.
So that the effectiveness of the airbag is not
reduced and that removed parts do not cause
any injuries or environmental pollution, regu-
lations must be observed. These require-
ments are known to specialised workshops.
Modifications to the vehicle suspension may
affect the operation of the airbag system in
the event of collision. For example, if wheel
and tyre combinations not approved by SEAT are used, or if the vehicle height is lowered,
the suspension is stiffened or the suspension
springs, telescopic arms, dampers, etc., are
modified, the results received by the airbag
sensors and sent to the control unit may not
be accurate. For example, some modifica-
tions to the suspension could increase the
force measured by the sensors and result in
the triggering of the airbag systems in colli-
sions. Under normal conditions, the meas-
ured values would be lower and the airbag
would not have been triggered. Other modifi-
cations may reduce the forces measured by
the sensors and prevent the airbags from be-
ing triggered when they should.
WARNING
Repairs or modifications which are not per-
formed correctly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the airbag systems. This could
result in serious or fatal accidents.
● All repairs and modifications to the vehicle
should only be performed by a specialised
workshop.
● Airbag modules must never be repaired: if
damaged, they must be replaced.
● Never fit recycled or reused airbag compo-
nents in your vehicle. WARNING
Modifications to the vehicle suspension, in-
cluding the use of unauthorised wheel and tyre combinations, may affect the perform-
ance of the airbags and increase the risk of
serious or fatal injury in the event of acci-
dent.
●
Never fit suspension components which are
not identical to the original parts in the vehi-
cle.
● Never use wheel and tyre combinations not
approved by SEAT. Retro-fitting of two-way radios
An exterior aerial is required for the use of
two-way radios in the vehicle.
The retro-fitting of electrical or electronic ap-
pliances in the vehicle is subject to their ap-
proval for use in your vehicle. Under certain
circumstances, this could mean that your ve-
hicle registration documents are no longer
valid.
SEAT has approved your vehicle for use with
two-way radios providing the following condi-
tions are observed:
● The exterior aerial must be mounted pro-
fessionally.
● The maximum transmitting power is 10
watts.
The optimal reach of the equipment is only
achieved with an external aerial.
120

Advice
WARNING
Solvents cause the surfaces of the airbag
modules to become porous. If an airbag is ac-
cidentally triggered, the detachment of plas-
tic parts could cause serious injury.
● Never clean the dash panel and the surfa-
ces of the airbag modules with cleaners con-
taining solvents. CAUTION
When cleaning the instrument panel, be care-
ful not to dampen the Portable Navigation
System connections as this can damage the
electrical installation. Cleaning seat belts
If the seat belt is very dirty, the belt retractor
may not work correctly thus preventing the
seat belt from operating correctly.
The seat belts should never be removed from
the vehicle for cleaning.
● Use a soft brush to remove the worst dirt
››› .
● Pull the seat belt right out and leave it out.
● Clean dirty seat belts with a gentle soap
and w at
er solution.
● Wait until they are completely dry.
● Only allow the seat belt to retract when it is
completely dry. WARNING
Check the condition of all the seat belts at
regular intervals. If the webbing or other
parts of the seat belt are damaged, the vehi-
cle should be taken to a Specialised work-
shop immediately and the belts should be re-
placed. It is extremely dangerous to drive us-
ing damaged seat belts and could result in
serious injury or loss of life.
● Seat belts and their components must nev-
er be cleaned with chemical products, nor
should they be allowed to come into contact
with corrosive liquids, solvents or sharp ob-
jects. This could affect the strength of the
seat belt webbing.
● Seat belts should be completely dry before
retracting. Dampness could damage the belt
retractor so that it does not operate correctly.
● Do not allow liquids or foreign bodies to en-
ter the buckle fastenings. This could damage
the buckles and seat belts.
● Never attempt to repair, modify or remove a
seat belt yourself.
● Always have damaged seatbelts replaced
immediately by seat belts approved for the
vehicle in question by SEAT. Seat belts which
have been worn in an accident and stretched
must be replaced by a specialised workshop.
Renewal may be necessary even if there is no
apparent damage. The belt anchorage should
also be checked. Notes for the user
Introduction WARNING
Failure to treat the vehicle with the correct
care increases the risk of accident and injury.
● Observe legal requirements.
● Observe the Instruction Manual. CAUTION
If the vehicle is not properly cared for, dam-
age may occur. ● Observe legal requirements.
● Carry out regular maintenance of the vehi-
cle, according to specifications in the Mainte-
nance Programme.
● Observe the Instruction Manual. 134

Advice
Tyres that are over 6 years old
Tyres are subject to an ageing process as a
result of physical and chemical processes.
This may affect their performance. Tyres
which are stored for long periods of time
without being used, harden and become
more fragile than tyres which are in constant
use.
SEAT recommends that tyres over six years
old are replaced with new tyres. This also ap-
plies to tyres (including the spare wheel)
which appear to be in perfect condition on
the outside and which have a tread depth
within the values stipulated by the Law ››› .
The date of manufacture, part of the tyre
identification number (TIN), indicates the age
of the tyre ( ) ››› page 167 .
St orin
g tyres
Mark tyres when you remove them to indicate
the direction of rotation (left, right, forwards,
backwards). This ensures you will be able to
mount them correctly when you replace
them. When removed, the wheels and/or
tyres should be stored in a cool, dry and pref-
erably dark location. Do not place tyres
mount

ed on the wheel in a vertical position.
Protect tyres not mounted on wheels from
dirt by storing them in suitable bags and
standing them on the ground on their tread. WARNING
Aggressive fluids or substances could result
in visible or invisible damage with the conse-
quent risks.
● Always ensure that tyres do not come into
contact with chemical products, oil, grease,
fuel, brake fluid or other aggressive substan-
ces. WARNING
Old tyres, even if they have never been used,
may lose air or burst unexpectedly while driv-
ing, resulting in serious accident or damage.
● If tyres are over six years old, they should
only be used in an emergency and with ex-
treme caution. For the sake of the environment
Old tyres must be disposed of by qualified
personnel according to the laws in the coun-
try concerned. Wheel rims
The design of wheel bolts is matched to the
rims. If different rims are fitted, the correct
wheel bolts with the right length and correct-
ly shaped bolt heads must be used. This en-
sures that wheels are fitted securely and that
the brake system functions correctly
››› page 174 . F
or t
echnical reasons, it is not generally pos-
sible to use the wheels from other vehicles.
In some cases, this may also be true for the
same model of wheel.
The tyres and rims approved by SEAT are spe-
cially matched to the characteristics of the
vehicle and are critical to good road holding
and safe handling.
Note for Italy:
A SEAT Service Centre should
be consulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
Wheel bolts
Wheel bolts must be tightened to the correct
torque ››› page 174
.
Beadlock wheel rims
Beadlock wheel rims have various compo-
nents. These are joined together by special
bolts using a special procedure. This ensures
good performance, a better seal, improved
safety and wheel run out. Therefore, worn
rims should always be replaced and must on-
ly be repaired in a specialised workshop.
SEAT recommends visiting a technical service
