Safe driving
– Always reduce your speed as appropriate for road, traffic and
weather conditions.
– When travelling long distances, take breaks regularly - at least
every two hours.
– If possible, avoid driving when you are tired or stressed.
WARNING
When driving safety is impaired during a trip, the risk of injury and acci-
dents increases.

24Seat belts
WARNING
● If the seat belts are worn incorrectly or not at all, the risk of severe
injuries increases. The optimal protection from seat belts can be ach-
ieved only if you use them properly.
● Fasten your seat belt before every trip - even when driving in town.
The other vehicle occupants must also wear the seat belts at all times,
otherwise they run the risk of being injured.
● The seat belt cannot offer its full protection if the seat belt is not
positioned correctly.
● Never allow two passengers (even children) to share the same seat
belt.
● Always keep both feet in the footwell in front of your seat as long as
the vehicle is in motion.
● Never unbuckle a seat belt while the vehicle is in motion. Risk of fatal
injury.
● The seat belt must never be twisted while it is being worn.
● The seat belt should never lie on hard or fragile objects (such as
glasses or pens, etc.) because this can cause injuries.
● Do not allow the seat belt to be damaged or jammed, or to rub on any
sharp edges.
● Never wear the seat belt under the arm or in any other incorrect posi-
tion.
● Loose, bulky clothing (such as an overcoat over a jacket) impairs the
proper fit and function of the seat belts, reducing their capacity to pro-
tect.
● The slot in the seat belt buckle must not be blocked with paper or
other objects, as this can prevent the latch plate from engaging securely.
● Never use seat belt clips, fastening rings or similar instruments to al-
ter the position of the belt webbing.WARNING (Continued)
● Frayed or torn seat belts or damage to the connections, belt retrac-
tors or parts of the buckle could cause severe injuries in the event of an
accident. Therefore, you must check the condition of all seat belts at reg-
ular intervals.
● 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.
● Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.
● The belts must be kept clean, otherwise the retractors may not work
properly.


48Child safety
WARNING
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger front airbag has been disabled. Risk of
potentially fatal injuries to the child! However, if it is necessary, in excep-
tional cases, to transport a child in the front passenger seat, the front
passenger front airbag must always be disabled ⇒ page 44. If the pas-
senger seat has a height adjustment option, move it to the highest, most
upright position. If you have a fixed seat, do not install any child restraint
system in this location.
● For those vehicles that do not include a key lock switch to deactivate
the airbag, the vehicle must be taken to a Technical Service.
● All vehicle occupants, especially children, must assume the proper
sitting position and be properly belted in while travelling.
● Never hold children or babies on your lap, this can result in potential-
ly fatal injuries to the child!
● Never allow a child to be transported in a vehicle without being prop-
erly secured, or to stand up or kneel on a seat while travelling. In an acci-
dent, the child could be flung through the vehicle, causing possibly fatal
injuries to themselves and to the other vehicle occupants.
● If children assume an improper sitting position when the vehicle is
moving, they expose themselves to greater risk of injury in the event of a
sudden braking manoeuvre or in an accident. This is particularly impor-
tant if the child is travelling on the front passenger seat and the airbag
system is triggered in an accident; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave an unsupervised child alone on a child seat or in the vehi-
cle.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.WARNING (Continued)
● Children who are less than 1.5 metres tall must not wear a normal
seat belt without a child seat, as this could cause injuries to the abdomi-
nal and neck areas during a sudden braking manoeuvre or in an accident.
● Do not allow the seat belt to become twisted or jammed, or to rub on
any sharp edges.
● Incorrectly worn seat belts can cause injuries even in a minor colli-
sion or in sudden braking manoeuvres.
● The seat belt provides maximum protection only when the seat belt is
properly positioned ⇒ page 25, Seat belts.
● Only one child may occupy a child seat ⇒ page 49, Child seats.

Windscreen wiper functions
Windscreen wiper performance in different situations:If the vehicle is at a stand-
still:The activated position provisionally changes
to the previous position.
During the automatic wipe:
The air conditioner comes on for approxi-
mately 30 seconds in air recirculation mode
to prevent the smell of the windscreen wash-
er fluid entering the inside the vehicle.
For the interval wipe:The intervals between wipes vary according
to the speed of the vehicle. The higher the
vehicle speed the shorter the intervals.
Heated windscreen washer jets
The heating only thaws the frozen jets, it does not thaw the water in the
washer hoses. The heated windscreen washer jets automatically adjust the
heat depending on the ambient temperature, when the ignition is switched
on.
Headlight wash/wipe system
The headlight washers/wipers clean the headlight lenses.
After the ignition is switched on, the first and every fifth time the wind-
screen washer is switched on, the headlights are also washed. Therefore,
the windscreen wiper lever should be pulled towards the steering wheel
when the dipped beam or main beam are on. Any incrusted dirt (such as in-
sects) should be cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work correctly in winter, any snow which
has got into the bumper jet supports should be cleaned away. If necessary,
remove snow with an anti-icing spray.
Note
The wiper will try to wipe away any obstacles that are on the windscreen.
The wiper will stop moving if the obstacle blocks its path. Remove the ob-
stacle and switch the wiper back on again. 
Windscreen wipers service position
Fig. 65 Wipers in service
position
The wiper arms can be raised when the wipers are in service position
⇒ Fig. 65. To place the windscreen wipers in the service position, proceed
as follows:
● The bonnet must be closed ⇒ page 209.
● Switch the ignition on and off.
● Press the windscreen wiper lever downwards briefly ⇒ Fig. 64 4
.
Before driving, always lower the wiper arms. Using the windscreen wiper
lever, the windscreen wiper arms return to their initial position. 

134Air conditioning
Air conditioning
Heating, ventilation, cooling
Introduction
Viewing Climatronic information
On the screen of Climatronic control unit and on the screen of the factory-
fitted Easy Connect 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 interior.
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 sta-
ted in the Service Schedule.
Additional information and warnings:
● Easy Connect system
● Seat functions
● Windscreen wipers and washers
● Caring for and cleaning the vehicle exterior
WARNING
Reduced visibility through the windows increases the risk of serious acci-
dents.
● Always ensure that all windows are free of ice and snow, and that
they are not fogged, so as to maintain good visibility of everything out-
side.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal run-
ning temperature. Only drive when you have good visibility.
● Always ensure that you use the heating system, fresh air system, air
conditioner and the heated rear window to maintain good visibility 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 required.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never leave the fresh air fan turned off or use the air recirculation for
long periods of time; the air in the vehicle interior will not be refreshed. 

Air conditioning
CAUTION
● Switch 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 specialist knowledge and special
tools. SEAT recommends visiting a SEAT Official Service.
Note
● When the cooling system is turned off, air coming from the outside will
not be dried. To prevent fogging of the windows, SEAT recommends leaving
the cooling system (compressor) turned on. To do this, press the button 
.
The button lamp should light up.
● The maximum heat output required to defrost 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 windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over. Air conditioner controls
