2014 Seat Altea air condition

168Air conditioning
Switching on manual mode
–To enter manual mode, press one of the buttons ⇒ Fig. 136 1
to 5 or press the air flow control 10. The selected function is
shown on the radio or navigator display.
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 temperatures from +18 °C (+64 °F) to +26 °C
(+80 °F). These are approximate temperatures and the actual temperature
may be slightly higher or lower depending on the ambient conditions.
If you select temperatures below +18 °C (+64 °F) the indication LO will ap-
pear on the screen. In this setting the system runs at maximum cooling out-
put and the temperature is not regulated.
If you select temperatures above +26 °C (+80 °F) the indication HI will ap-
pear on the screen. In this setting the system runs at maximum heating out-
put and the temperature is not regulated.
Blower
The air flow may be adjusted freely using the control 10
. 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, turns 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 on and off
When the AC
button is on (LED lit), the air conditioning system is on.
When the AC
button is off (LED off), the air conditioning system is off. When the
AC
button is off, the air conditioning system is switched off to
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The SYNC
button controls the synchronisation of the 2 Climatronic climate
zones.
When the SYNC
button is off (LED off), the climate zone of the Climatronic is
personalised. For example: driver side temperature +22 °C (+72 °F) and pas-
senger side temperature +24 °C (+75 °F).
When the SYNC
button is on (LED lit), the climate zone of the Climatronic is
synchronised. For example: driver side temperature +22 °C (+72 °F) and
passenger side temperature +22 °C (+72 °F).
If the SYNC
button is on and the passenger side temperature is changed,
the function is automatically deactivated. 
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button 
⇒ Fig. 136
2 to switch air recirculation
mode on or off. It is switched on if the following symbol appears
in the display .
Air recirculation mode prevents strong odours in the ambient air from enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside. 

169
Air conditioning
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. 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 connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows 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 barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Plan.
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 occupants 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 following reasons:
●
The engine is not running.
● The AC
button is disconnected.
● The outside temperature is lower than approximately +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 speci-
alised workshop.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
workshop.
Note
● If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a pud-
dle underneath 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 are not impaired, and to prevent the
windows from misting over.
● The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects. 

170Air conditioning
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the temperature inside the vehi-
cle 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 conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
● It is advisable to connect the air conditioning at least once a month, to
lubricate the system gaskets and prevent leaks. If a decrease in the cooling
capacity is detected, a Technical Service should be consulted to check the
system. 

Driving
Start-Stop function*
Description and operation
The Start-Stop function stops the engine when the vehicle is stop-
ped and starts it automatically when required.
– When the vehicle is stopped, put it in neutral and release the
clutch pedal. The engine will stop.
– When the clutch pedal is pressed, the engine starts again.
– The instrument panel display shows information about the sta-
tus of the Start-Stop function ⇒ Fig. 143.
Start-Stop function conditions
● The driver seat belt must be buckled.
● The bonnet must be closed.
● The engine must be at operating temperature.
● The steering wheel must not be turned more than 270°.
● The vehicle must not be on a steep gradient.
● The vehicle must not be in reverse.
● A trailer must not be connected.
● The temperature of the passenger compartment must be within the com-
fort limits (button AC
11 ⇒ Fig. 136 should be selected).
● The windscreen de-mist function must be off.
● If not, it requires an increase in airflow 10
⇒ Fig. 136 for more than three
presses.
● The temperature must not be set to HI or LO.
● The driver door must be closed.
● The diesel particulate filter must not be in regeneration mode, for diesel
engines. ●
The battery charge must not be low for the next start.
● The battery temperature must be between -1 °C (+30 °F) and +55 °C
(+131 °F).
● The Parking aid system (Park Assist*) must not be activated.
Start-Stop function interruption
In the following situations, the Start-Stop function will be interrupted and
the engine will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in a row.
● The battery has been discharged excessively.
● The Start-Stop System is manually deactivated.
● The windscreen de-mist function is turned on.
● The temperature of the passenger compartment exceeds the comfort
limits (button AC
11 ⇒ Fig. 136 should be selected).

presses.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insufficient.
● The alternator is faulty, for example the V-belt has ruptured.
● If any of the conditions described in the previous section are not fulfil-
led.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and seri-
ous injury.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving through water (fording
streams, etc.). 

200Intelligent technology
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed that the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled
down.
WARNING
● When accelerating on a slippery surface, for example on ice and
snow, press the accelerator carefully. Despite EDL, the driven wheels may
start to spin. This could impair the vehicle's stability.
● Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into tak-
ing any risks when driving, this can cause accidents.
CAUTION
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the EDL ⇒ page 226. 
Drive wheel traction control system (ASR)
The traction control system prevents the driven wheels from spinning when
the vehicle is accelerating ⇒ page 197. All-wheel drive*
On all-wheel drive models, the engine power is distributed
to all four wheels
General notes
The all-wheel drive system operates completely automatically. The propul-
sion force is distributed among the four wheels and adapted to the driving
style and the road conditions.
The all-wheel drive is specially designed to complement the superior engine
power. This combination gives the vehicle exceptional handling and per-
formance capabilities, both on normal roads and in more difficult condi-
tions, such as snow and ice.
Winter tyres
Thanks to its all-wheel drive, your vehicle will have plenty of traction in win-
ter conditions, even with the standard tyres. Nevertheless, we still recom-
mend that winter tyres or all-season tyres should be fitted on all four wheels
when winter road conditions are expected, mainly because this will give a
better braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars with
all-wheel drive.
Changing tyres
On vehicles with all-wheel drive, all four tyres must have the same rolling
circumference ⇒  page 258. 

201
Intelligent technology
WARNING
● Even with all-wheel drive, you should always adjust your speed to
suit the conditions. Do not let the extra safety features tempt you into
taking any risks when driving. Failure to do so could result in an accident.
● The braking capability of your vehicle is limited by the tyres' grip. Ve-
hicle behaviour is no different from a vehicle without four-wheel drive. So
do not be tempted to drive too fast on icy or slippery roads just because
the vehicle still has good acceleration in these conditions. Failure to do
so could result in an accident.
● On wet roads bear in mind that the front wheels may start to aqua-
plane and lose contact with the road if the vehicle is driven too fast. If
this should happen, there will be no sudden increase in engine speed
when aquaplaning begins to warn the driver, as with a front-wheel drive
vehicle. For this reason and for that mentioned above, always choose a
driving speed suitable for the road conditions. Failure to do so could re-
sult in an accident.

Brakes
What factors can have a negative effect on the brakes?
New brake pads
New brake pads do not provide optimal performance during the first 400 km
(250 miles); first they must be “run in”. However, the reduced braking ca-
pacity may be compensated by pressing on the brake pedal a little harder.
Avoid overloading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive
and the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops. Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle is driven for some distance without using the brakes when there is a lot
of salt on the road in winter. In this case, the layer of salt on the brake discs
and pads has to wear off before braking.
Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times at a
moderately high speed
⇒ 
.
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may mean that
one of the two brake circuits has failed. Drive immediately to the nearest
specialised workshop and have the fault repaired. Drive there slowly and re-
member that you will have to apply more pressure on the brake pedal and
allow for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is too
low. The brake fluid level is monitored electronically.
Brake servo
The brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running. 

Driving and the environment
WARNING (Continued)
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 226, Technical modifi-
cations.
● If a brake system circuit fails, the braking distance will be increased
considerably. Contact a specialised workshop immediately and avoid un-
necessary journeys.

Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank. –
For engine oil changes, do not replenish with too much engine
oil ⇒ page 241, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 287.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 76. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
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.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. 

Vehicle maintenance and cleaning
CAUTION
If the upholstery on electrically operated seats or seats with airbag compo-
nents gets soaked, the vehicle's electric system and certain other compo-
nents may be damaged.
● If the seat gets soaked, take the vehicle immediately to a specialised
workshop to be dried and for the system components to be inspected.
● Do not use steam cleaning equipment as the dirt becomes more encrus-
ted and fixed in the material.
● High-pressure cleaning equipment and cold aerosols may damage the
upholstery.
CAUTION
● Brushes should only be used to clean the carpet and floor mats! Other
fabrics may be damaged if cleaned with a brush.
● If cream detergents or detergents for delicate garments are applied with
a damp cloth or sponge, they may, for example, leave rings when dry be-
cause of the surfactant components they contain. Generally, such rings are
very difficult or almost impossible to remove.
CAUTION
● Do not let water soak into Alcantara ®
under any circumstances.
● Do not use leather cleaning products, solvents, wax polish, shoe cream,
stain removers or similar products on Alcantara ®
.
● Never use brushes for cleaning damp material as they could damage the
surface. 
Cleaning and maintenance of natural leather upholstery
Consult a professional cleaning workshop if you have any doubts on clean-
ing and maintaining the leather equipment in your vehicle. Maintenance and treatment
Nappa natural leather is delicate because it has no additional protective
layer.
●
After cleaning, regularly apply a conditioner with sun-screen and im-
pregnating action. These products nourish the leather, soften it and make it
more breathable, as well as re-hydrating it. They also provide it with a pro-
tective film.
● Clean the leather every two or three months and remove stains as they
appear.
● Treat the leather regularly (about twice a year) with a suitable mainte-
nance product.
● Apply as few cleaning and maintenance products as possible, always
using a dry, lint-free cotton or woollen cloth. Do not apply cleaning and
maintenance products directly to the leather.
● Remove recent ball-point pen and ink stains, lipstick, shoe cream and
similar stains as soon as possible.
● Maintain the colour of the leather. To do this, use a special cream espe-
cially coloured for leather to achieve the same overall colour, if necessary.
● Afterwards, go over it with a soft cloth.
Cleaning the vehicle
SEAT recommends using a slightly damp cotton or woollen cloth for general
cleaning purposes.
Generally, the leather should never be soaked at any point, nor should wa-
ter penetrate the seams.
Before cleaning the leather upholstery, bear in mind the following recom-
mendations ⇒ page 222, Cleaning the fabric on heated seats and electrical-
ly adjustable seats or seats with airbag components. 
