2015 Seat Altea service schedule

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

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

Safety

Advice
Checking the electrolyte level The electrolyte level should be checked regu-
larly in high-mileage vehicles, in hot coun-
tries and in older batteries.
– Open the bonnet and open the battery cov-
er at the front ››› in Safety instructions
on working in the engine compartment on
page 164 ››› in Warnings on handling
the battery on page 173.
– Check the colour display in the "magic eye"
on the top of the battery.
– If there are air bubbles in the window, tap
the window gently until they disperse.
The position of the battery is shown in the
corresponding engine compartment diagram
››› page 166 .
The “m agic
eye” indicator, located on the top
of the battery changes colour, depending on
the charge state and electrolyte level of the
battery.
There are two different colours:
● Black: correct charge status.
● Transparent/clear yellow: the battery must
be replaced. Contact a specialised workshop. Charging and changing the vehicle
battery The battery is maintenance-free and is
checked during the inspection service. All
work on the vehicle battery requires special-
ist knowledge.
If you often drive short distances or if the ve-
hicle is not driven for long periods, the bat-
tery should be checked by a specialised
workshop between the scheduled services.
If the battery has discharged and you have
problems starting the vehicle, the battery
might be damaged. If this happens, we rec-
ommend you have the vehicle battery
checked by a Technical Service where it will
be re-charged or replaced.
Charging the battery
The vehicle battery should be charged by a
specialised workshop only, as batteries us-
ing special technology have been installed
and they must be charged in a controlled en-
vironment.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features.
Genuine SEAT batteries meet the mainte-
nance, performance and safety specifications
of your vehicle. WARNING
● We recommend you use only maintenance-
free or cycle free leak-proof batteries which
comply with standards T 825 06 and
VW 7 50 73. This standard applies as of
2001.
● Before starting any work on the batteries,
you must read and observe the warnings
››› in Warnings on handling the battery on
page 173. For the sake of the environment
Batteries contain toxic substances such as
sulphuric acid and lead. They must be dis-
posed of appropriately and must not be dis-
posed of with ordinary household waste. 174
