2007 Seat Altea heating

Heating, Ventilation and Air conditioning
154Air recirculation mode ⇒page 153, fig. 126 prevents strong odours in
the outside air from entering the vehicle interior, for example when passing
through a tunnel or in queuing traffic.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the air from outside.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the air from outside. For reasons of safety, air recirculation is
not possible when the control for air
distribution is set to the windscreen setting
.
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.
2C-Climatronic*Control switches
The controls allow separate adjustment of air conditioning settings for the left and right.

– Press the temperature selectors to set the desired temperatures
for the left and right sides of the interior. We recommend 22°C
(72°F).A comfortable interior climate is quickly reached when a temperature of
+22°C (72°F) is set in automatic mode. It can be changed as necessary to suit
individual preferences or particular ci rcumstances. It is possible to select
interior temperatures from +16°C (61°F) to +29.5°C (86°F). These are approx-
imate temperatures and the actual temperature may be slightly higher or
lower depending on the ambient conditions. Climatronic automatically maintains a constant temperature. The tempera-
ture of the air supplied to the interior, the blower speed and the air distribu-
tion are regulated automatically. The system also allows for the effect of
strong sunlight, so there is no need
for manual adjustment. Therefore, auto-
matic mode provides the best comfort for the vehicle occupants in virtually all
conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, airflow or . The temperature will
continue to be regulated within the parameters manually selected by the
user.Manual mode
In manual mode you can adjust the air temper ature, airflow and distribution as required.Switching on manual mode

Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector. It
is possible to select interior tem
peratures from +16°C (61°F) to +29.5°C
(86°F). These are approximate temperat ures and the actual temperature may
be slightly higher or lower depending on the ambient conditions.
If a temperature below 16°C (61°F) is selected, the display switches to LO. In
this setting the system runs at maximum cooling output and the temperature
is not regulated.
If a temperature above 29.5°C (86°F) is selected the display switches to HI. In
this setting the system runs at maximum heating output and the temperature
is not regulated.
Blower
The airflow may be adjusted freely using the control . Always have the
blower running at a low setting to ensure a constant flow of fresh air into the
vehicle. Pushing the button
 to the minimum -1, tu rns the Climatronic off.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air vents separately.
Switching the air conditioning system on and off
Pressing the button switches off the air conditioning system to save
fuel. The temperature continues to be regulated. The set temperature can
then only be reached if it is higher than the ambient temperature.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.– Press the button ⇒page 156, fig. 128 to switch air recir-
culation mode on or off. It is switched on if the following symbol

158General notesThe pollen filter
The pollution filter (a combined pa rticulate filter and activated carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filte r must be changed more frequently than
stated in the Service Schedule.
Caution
•
If you suspect that the air conditioner is damaged, switch off the air condi-
tioner with button to prevent further damage and have it checked by a
qualified workshop.
•
Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend that you take the vehicle to a quali-
fied workshop should problems occur.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle, this is completely normal and there is no need to suspect
a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling is not impaired, and to prevent the
windows misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Do not cover these slots with
articles of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. Howe ver, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a r esidue on the evaporator, producing a
permanent unpleasant odour.
•
The air conditioning should be turned on at least once a month, to lubri-
cate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.

– Let go of the ignition key as soon as the engine starts; the starter
motor must not be allowed to run on with the engine.After starting a very hot e ngine, you may need to pres s the accelerator briefly.
When starting from cold, the engine ma y be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine does not start immediatel y, switch off the starter after about
10 seconds and try again after about half a minute. If the engine still does not
start, the fuel pump fuse should be checked ⇒page 242, “Fuses”.
WARNING
•
Never start or run the engine in unventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should avo id high engine speeds, driving at
full throttle and ov erloading the engine. Risk of engine dama ge.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒ page 258, “Jump-starting”.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Starting diesel engines
The engine can only be started using a genuine SEAT key with
the correct code.– Move the gear lever to the neutral position and depress the clutch pedal fully and hold it in this position, the starter will then
only have to turn the engine.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 161, fig. 132 . The
indication lamp

will light for engine pre-heating.
– When the warning lamp goes out, turn the key to position to start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the starter motor must not be allowed to run on with the engine.
When starting from cold, the engine ma y be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see ⇒page 258.

164Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 81 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start the engine afte r refuelling with diesel fuel. This is
because the system must eliminate air first.
WARNING
•
Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon mono xide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should av oid high engine speeds, driving at
full throttle and over loading the engine. Risk of engine damage.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒page 258, “Jump-starting”.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Switching off the engine– Stopping the engine.
– Turn the ignition key to position ⇒page 161, fig. 132 .After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched of f. It is also possible that it will turn
itself on once more if the temperature of the coolant increases due to the
elimination of built-up heat in the engine compartment or if this is heated due
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need
more strength to brake the vehicle when the engine is switched off. As you
cannot brake in the normal manner, there is a greater risk of accidents and
serious injury.
•
The steering lock can engage immediately when the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.

Hill stop
– Hold the vehicle, in all cases, using the foot brake to prevent
rolling back.
– Do not try to slow the vehicle using another forward gear (engine braking).
Descending gradients
– With the gear engaged, release the brake and accelerate.The steeper the gradient the lower the gear must be for effective engine
braking. For example, if 3rd gear is used on a very steep gradient, the engine
braking is insufficient and vehicle accelerates. So that the engine speed does
not become excessive, the gearbox changes to the next highest gear. Depress
the brake pedal and move the selector lever to the Tiptronic gate to return to
3rd gear.
WARNING
•
The driver should never leave the vehicle while the engine is running or
with any gear selected. If for any reason you must leave the vehicle with the
engine running, apply the handbrake and move the selector lever to posi-
tion P.
•
When the engine is running and the po sitions D, S or R are selected, it
is necessary to hold the vehicle with the foot brake because the vehicle will
creep at a low speed.
•
Never accelerate while changing the position of the selector lever (risk
of an accident).
•
The selector lever must never be mo ved into the positions R or P while
moving (risk of an accident).
•
Before descending a steep gradient, reduce speed and use the Tiptronic
programme to select a lower gear.
•
If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back.
•
The footbrake must not be held for a long period of time, not even
lightly; continuous braking will ca use overheating of the brakes and a
reduction or even a loss of braking power and a significant increase in
braking distances.
•
Never allow the vehicle to coast down a gradient with the selector lever
in positions N or D, even when the engine is not running. For descents, the
use of the Tiptronic programme is recommended to keep the speed
reduced.Caution
•
Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause damage.
Apply the handbrake or depress the foot brake to hold the vehicle in position.
•
If the vehicle is allowed to roll with the engine stopped but the selector in
position N then the gearbox may be damaged because it will not be
lubricated.WARNING (continued)
