2015 Seat Altea XL air condition

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

Quality requirements for LPG are regulated
for all Europe in DIN EN 589 and permit the
use of LPG throughout Europe without any
problems.
LPG is a mixture of propane and butane.
A difference is drawn between winter gas and
summer gas. Winter gas has a higher propor-
tion of propane gas. As a result, the driving
range of winter gas may be lower (due to in-
creased consumption) than that of summer
gas.
The vehicle's engine management adapts au-
tomatically to the LPG used. Therefore, both
types of LPG can be mixed in the tank, with-
out the need for comprehensive draining be-
fore applying a different quality LPG. LPG and safety
If you smell gas or suspect that there is a
leak in the LPG system.
››› ●
Stop the vehicle immediately.
● Switch the ignition off.
● Open all the doors to properly ventilate the
vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off
objects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek specialist assistance. Have the fault
repaired. WARNING
LPG is a highly explosive and inflammable
substance. It may cause severe burns and
other injury.
● Due care must be taken to avoid any risk of
fire or explosion.
● When parking the vehicle in a closed area
(for example in a garage), make sure that
there is adequate ventilation, either natural
or mechanical, to neutralise the LPG in the
event of a leak. WARNING
Failure to act when you can smell gas in the
vehicle or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. Note
● The LPG system must be subject to regular
inspections at a specialised workshop in ac-
cordance with the Maintenance Plan.
● The engine is always started with petrol,
even when LPG was being used when it was
switched off. For this reason the tank should
never be drained of petrol completely.
● If frequent short journeys are made, espe-
cially when the outside temperature is low,
the vehicle will tend to run on petrol more of-
ten than on LPG. Therefore, the petrol tank
may empty before the LPG tank.
● If while driving the system switches auto-
matically to petrol operating mode because
the LPG tank is almost empty, the next few
times the engine starts up, and depending on
the outside temperature and driving style, it
may automatically switch briefly to LPG oper-
ating mode to use up what is left in the tank.
● When the system automatically switches to
petrol operating mode because the LPG tank
is almost empty, you can revert to gas operat-
ing mode by pressing the ››› Fig. 121 GAS »

engine compartment or due to its prolonged
exposure to solar radiation. WARNING
● Never switch the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is running. With the engine switched off,
more strength is needed to brake. As normal
brake operation cannot be performed, risk of
accidents and serious injury may exist.
● The steering lock can be immediately
blocked once the key is removed from the ig-
nition. The vehicle cannot be steered. Risk of
accident. CAUTION
When the engine has been running under a
heavy load for a long period, heat can accu-
mulate in the engine compartment and cause
engine damage. For this reason, idle the en-
gine for approximately 2 minutes before
switching it off. Braking and parking
Braking capacity and distance The following factors impair braking capacity: New brake pads
New brake pads do not provide optimal per-
formance during the first 400 km; first they
must be “run in”. However, the reduced brak-
ing capacity may be compensated by press-
ing 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 condi-
tions in which the vehicle is operated. Nega-
tive factors are, for instance, city traffic, fre-
quent 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 vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. In this case, the layer of salt on the brake
discs and pads has to wear off before brak-
ing. 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
br ak
e circuits has failed. Drive immediately
to the nearest specialised workshop and
have the fault repaired. Drive there slowly
and remember 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 flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. »

Driving
●
If the handbrake is only partially released,
this will cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehicle. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
plied when the vehicle is parked.
Always note the following points when park-
ing the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. Turn the steering wheel
slightly to engage the steering lock.
– Always take you keys with you when you
leave the vehicle ››› .Additional notes on parking the vehicle on
gradients:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
●
If the vehicle is parked facing downhill,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill, turn
the fr ont
wheels so that they point away from
the kerb
.
● Secure the vehicle as usual by applying the
handbrake firmly and putting it in 1st gear. WARNING
● Take measures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
could ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehicle when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They could set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever. ●
Depending on weather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill without rolling
backward.
The system maintains brake pressure for ap-
proximately 2 seconds after the driver takes
his foot off the brake pedal to prevent the ve-
hicle from rolling backward when starting off.
During these 2 seconds, the driver has
enough time to release the clutch pedal and
accelerate without the vehicle moving and
without having to use the handbrake, making
starting off easier, more comfortable and saf-
er.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● closed doors,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S,
D
or R for an au-
tomatic gearbox. »

Operation
without EDL. For this reason, the driver is not
informed 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 accel-
erator 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 in-
to taking any risks when driving, this can
cause accidents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the brake system, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 147. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
only included in vehicles with ESC.
In an emergency, most drivers brake in time,
but not with maximum force. This results in
unnecessarily long braking distances. This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake.
Emergency braking warning
If the vehicle is braked suddenly and continu-
ously at a speed of more than 80 km/h, the
brake light flashes several times per second
to warn vehicles driving behind. If you contin-
ue braking, the hazard warning lights will
come on automatically when the vehicle
comes to a standstill. They switch off auto-
matically when the vehicle starts to move
again.
WARNING
● The risk of accident is higher if you drive
too fast, if you do not keep your distance from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist system.
● The brake assist system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with the brake assist system! Therefore, it is essential that you adjust your
speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you
into taking any risks when driving.
Anti-lock brake system (ABS)
The anti-lock brake (ABS) system prevents
the wheels from locking during braking and
is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels turns too slowly in rela-
tion to the vehicle's speed, and is close to
locking, the system will reduce the braking
pressure to this wheel. The driver is made
aware of this control process by a
pulsating
of the brake pedal and audible noise. This is
a deliberate warning to the driver that one or
more of the wheels is tending to lock and the
ABS control function has intervened. In this
situation it is important to keep the brake
pedal fully depressed so the ABS can regu-
late the brake application. Do not “pump”.
If you brake hard on a slippery road surface,
the best possible control is retained as the
wheels do not lock.
However, ABS will not necessarily guarantee
shorter braking distances in all conditions.
Br ak
ing distance could even be further if you
136

Operation
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise,
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected.
Brake servo The brake servo increases the pressure you
apply to the brake pedal. It works
only when
the engine is running .
If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
external factors.
● Never let the vehicle coast with the engine
switched off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the vehicle is being towed, you will have to press the brake pedal considerably
harder than normal.
Start-Stop System*

Advice
●
Never use brushes for cleaning damp mate-
rial as they could damage the surface. Cleaning and maintenance of natural
leather upholstery
Consult a professional cleaning workshop if
you have any doubts on cleaning and main-
taining 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 condition-
er with sun-screen and impregnating 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 maintenance 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 especially 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 cot-
ton or woollen cloth for general cleaning pur-
poses.
Generally, the leather should never be
soaked at any point, nor should water pene-
trate the seams.
Before cleaning the leather upholstery, bear
in mind the f o
llowing recommendations
››› page 154, Cleaning the fabric on heated
seats and electrically adjustable seats or
seats with airbag components . CAUTION
● On no account use solvents, wax polish,
shoe cream, stain removers or similar materi-
als on leather.
● If the stain remains on the leather for long,
it will soak in and be impossible to remove.
● In the event of spilt liquids, dry immediate-
ly with an absorbent cloth to prevent the liq-
uid penetrating through the leather or seams. ●
If the vehicle is left standing in the sun for
long periods, the leather should be protected
against direct sunlight to prevent it from fad-
ing. Note
The leather will usually change colour slight-
ly with use. Cleaning synthetic leather upholstery
Before cleaning synthetic leather upholstery,
bear in mind the following recommendations
››› page 154, Cleaning the fabric on heated
seats and electrically adjustable seats or
seats with airbag components
Only use water and neutral cleaning products
to clean synthetic leather upholstery. CAUTION
Do not use solvents, floor wax, shoe cream,
stain removers or similar products on syn-
thetic leather. These will stiffen the material,
causing it to crack prematurely. Cleaning plastic parts and the
instrument panel
–
Use a clean, damp cloth to clean plastic
parts and the dash panel.
