2015 Seat Altea cooling

Operation
If the windscreen air output is on and air re-
circulation mode is pressed, this remains ac-
tive. When the recirculation mode is on, if the
air distribution towards the windscreen mode
is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation
mode should not be connected. WARNING
In air recirculation mode, no cold air from the
outside enters the vehicle interior. If the air
conditioning system is switched off, the win-
dows can quickly mist over. Therefore, never
leave the air recirculation mode switched on
for a long time (risk of accident). General notes
Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. Air conditioner
When the air conditioning system is switched
on, not only the temperature, but also the air
humidity in the vehicle interior is reduced.
This improves comfort for the vehicle occu-
pants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be
switched on this may be caused by the fol-
lowing reasons:
● The engine is not running.
● The A/C button is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● The air conditioning system compressor
has been temporarily switched off because
the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop. CAUTION
● If you suspect that the air conditioner is
damaged, switch it off with the A/C button to
prevent further damage and have it checked
by a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and temperature 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.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and is extracted by slots de-
signed for this purpose. Therefore, do not
cover these slots with items of clothing or
other objects.
● The air conditioner operates most effective-
ly with the windows and the sliding/tilting
sunroof* closed. However, if the temperature
inside the vehicle is excessive because of the
sun, the air inside can be cooled faster by
opening the windows for a short time.
● Do not smoke while air recirculation mode
is on, as smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour.
● It is advisable to turn on the air condition-
ing at least once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system. 116

Driving
From 1,000 to 1,500 kilometres
– Speeds can be gradually increased to the
maximum road speed or maximum
permissible engine speed (rpm).
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on, when all the moving parts have bed-
ded in. For the sake of the environment
If the engine is run in gently, its life will be in-
creased and its oil consumption reduced. Environmental friendliness
Environmental protection is a top priority in
the design, choice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage
recycling
● Joints and connections designed for easy
dismantling
● Modular construction to facilitate disman-
tling
● Increased use of single-grade materials.
● Plastic parts and elastomers are marked in
accordance with ISO 1043, ISO 11469 and
ISO 1629. Choice of materials
●
Use of recycled materials.
● Use of compatible plastics in the same part
if its components are not easily separated.
● Use of recycled materials and/or materials
originating from renewable sources.
● Reduction of volatile components, includ-
ing odour, in plastic materials.
● Use of CFC-free coolants.
Ban on heavy metals, with the exceptions
dictated by law (Annex II of ELV Directive
2000/53/EC): cadmium, lead, mercury, hexa-
v al
ent chromium.
Manufacturing methods
● Reduction of the quantity of thinner in the
protective wax for cavities.
● Use of plastic film as protection during ve-
hicle transport.
● Use of solvent-free adhesives.
● Use of CFC-free coolants in cooling sys-
tems.
● Recycling and energy recovery from resi-
dues (RDF).
● Improvement in the quality of waste water.
● Use of systems for the recovery of residual
heat (thermal recovery, enthalpy wheels,
etc.).
● Use of water-soluble paints. Catalytic converter To maintain the useful life of the catalytic
converter
– Use only unleaded petrol with petrol en-
gines, as lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too much engine oil ››› page 168, Top-
ping up engine oil .
– Never tow the vehicle to start it, use jump
leads if necessary ›››
page 189.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 35 . If this happens,
u nb

urnt fuel can enter the exhaust system
and escape into the environment. The cata-
lytic converter can also be damaged by over-
heating. WARNING
The catalytic converter reaches very high
temperatures! Risk of fire!
● Never park where the catalytic converter
could come into contact with dry grass or
flammable materials under the vehicle. » 131

Fitting a towing bracket* Fig. 138
Attachment points for towing brack-
et. If a towing bracket is to be fitted after the ve-
hicle is purchased, this must be completed
according to the instructions of the towing
bracket manufacturer. The attachment points for the towing bracket
A are on the lower part of the vehicle.
The distance between the centre of the ball
coupling and the ground should never be
lower than the indicated value, even with a
fully loaded vehicle and including the maxi-
mum drawbar load.

●
Driving with a trailer involves an extra effort
for the vehicle. Therefore, before fitting a
towing bracket, please contact a Technical
Service to check whether your cooling system
needs modification.
● The legal 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, must 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 attachment points which
must be considered if you are retrofitting a
towing bracket. WARNING
The towing brackets should be fitted at a spe-
cialised workshop.
● If the towing bracket is incorrectly instal-
led, there is a serious danger of accident.
● For your own safety, please observe the tow
bracket manufacturer's instructions. CAUTION
● If the power socket is incorrectly installed,
this could cause damage to the vehicle elec-
trical system. Note
For the sports model (Altea FR), fitting of a
trailer bracket is not recommended due to the
design of the bumpers. 146

Advice
You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 147 . The engine compart-
ment of
the vehicle is a hazardous area.
››› .
WARNING
All work on the engine or in the engine com-
partment, e.g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● Apply the handbrake and move the gear
lever to neutral or selector lever to position P.
● Keep children away from the vehicle. ●
Never touch hot engine parts. There is a
risk of burns.
● Never spill liquids on a hot engine or on a
hot exhaust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal system, particularly at the points where
the jump leads are attached ››› page 190. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a large, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, such as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
system or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. CAUTION
When topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! 164

Checking and refilling levels
Changing engine oil The engine oil must be changed at the inter-
vals given in the service schedule.
We recommend that you have the engine oil
changed by a Technical Service.
The oil change intervals are shown in the
Maintenance Programme.
WARNING
Only change the engine oil yourself if you
have the specialist knowledge required!
● Before opening the bonnet, read and ob-
serve the warnings ››› page 163, Safety in-
structions on working in the engine compart-
ment.
● Wait
for the engine to cool down. Hot oil
may cause burn injuries.
● Wear eye protection to avoid injuries, such
as acid burns, caused by splashes of oil.
● When removing the oil drain plug with your
fingers, keep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact with engine oil.
● Engine oil is poisonous! Used oil must be
stored in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This could result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty. For the sake of the environment
● Because of disposal problems and the spe-
cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service.
● Never pour oil down drains or into the
ground.
● Use a suitable container when draining the
used oil. It must be large enough to hold all
the engine oil. Cooling system
Engine coolant specifications The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13 F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must
always be at
l e

ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would
reduce frost protection and, in turn, decrease
cooling capacity.
When the coolant is topped up, use a mixture
of distilled water and, at least, 40 % of the G
13 or G 12 plu

s-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› . The mixture of G
13 with G 12 plus (TL-VW 774 F), G 12 (red) or
G 11 (green-blue) engine coolants will signifi-
cantly reduce the anticorrosion protection
and should, therefore be avoided ››› .
WARNING
If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive is correct with respect to the lowest
expected ambient temperature in the zone
where the vehicle is to be used.
● When the outside temperature is very low,
the coolant could freeze and the vehicle » 169

would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold.
CAUTION
The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system. ● If the fluid in the expansion tank is not pur-
ple but is, for example, brown, this indicates
that the G 13 additive has been mixed with
an inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Checking the coolant level and
topping up
Fig. 149
Engine compartment: coolant expan-
sion tank cap. Top up coolant when the level is below the
MIN (minimum) mark.
Before opening the bonnet, read and observe
the warnings
››› in Safety instructions on
working in the engine compartment on
page 163 .
Openin g the c
oolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the
coolant expansion tank with a thick cloth
and carefully unscrew the cap ››› .
Checking coolant level
– Look into the open coolant expansion tank
and read off the coolant level. –
If the level is below the “MIN” mark, top up
with coolant.
Topping up coolant – Only use new coolant liquid.
– Do not fi

ll above the “MAX” mark.
Closing the coolant expansion tank – Screw the cap on again tightly.
The position of the coolant expansion reser-
voir is shown in the corresponding engine
compartment illustration ››› page 166.
Make sure that the coolant meets the re-
quired specifications ››› page 169. Do not use
a different type of additive if additive G12+ is
not available. In this case use only water and
bring the coolant concentration back up to
the correct level as soon as possible by put-
ting in the specified additive ››› page 169.
Always top up with new coolant.
Do not fi

ll above the “MAX” mark. Otherwise
the excess coolant will be forced out of the
cooling system when the engine is hot.
The coolant additive G12+ (dyed purple) may
be mixed with G12 (dyed red) and also with G
11.

Checking and refilling levels
WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
● When working in the engine compartment,
always observe the safety warnings
››› page 163.
● When the engine is warm or hot, the cool-
ing system is pressurised! Do not unscrew
the cap on the coolant expansion tank when
the engine is hot. This is a burn injury risk. CAUTION
● When mixed with other additives the colour
of G12 will change to brown. If this occurs
you should have the coolant changed imme-
diately. Failure to do so will result in engine
damage!
● If a lot of coolant fluid has been lost, wait
for the engine to cool. This avoids damaging
the en gine. Lar
ge coolant losses are an indi-
cation of leaks in the cooling system. See a
specialised workshop immediately and have
the cooling system checked. Otherwise, there
is a risk of engine damage. Windscreen washer reservoir
Topping up washer fluid  Fig. 150
In the engine compartment: Cap of
windscreen washer fluid reservoir The
windscreen washer
and the
headlight
washers are supplied with fluid from the
windscreen washer fluid container in the en-
gine compartment. The container holds ap-
prox. 3 litres; in vehicles with headlight
washers* it holds approx. 5.5 litres.
The reservoir is located on the right-hand
side of the engine compartment.
Plain water is not enough to clean the wind-
screen and headlights. We recommend that
you always add a product to the windscreen
washer fluid. Approved windscreen cleaning
products exist on the market with high deter-
gent and anti-freeze properties, these may be
added all-year-round. Please follow the dilu-
tion instructions on the packaging. WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
● When working in the engine compartment,
always observe the safety warnings
››› page 163. CAUTION
● Never put radiator anti-freeze or other addi-
tives into the windscreen washer fluid.
● Always use approved windscreen cleansing
products diluted as per instructions. If you
use other washer fluids or soap solutions,
the tiny holes in the fan-shaped nozzles
could become blocked. 171
