124imate temperatures which may slightly vary depending on the outside condi-
tions.
Climatronic maintains a constant temperature. To do it, it automatically regu-
lates the supplied air temperature, the blower speed and the air distribution.
The system also considers the sunlight radiation, so there is no need for
manual readjustment. Therefore, automatic mode almost always provides
the best comfort for the vehicle occupants throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, blower or . The temperature continues to
self-regulate.Manual mode
In manual mode the air temperature, flow, and the desired air
distribution can be adjusted.Switching on manual mode
– Press one of the buttons ⇒ page 122, fig. 92 to or press
the blower control and down. The indicator is switched
off.Te m p e r a t u r e
The passenger compartment temperature can be set between +18°C (64°F)
and +29°C (86°F). These are approximate temperatures which may slightly
vary depending on the outside conditions.
If a temperature below 18°C (64°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°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 controlled.
Blower
The blower can be adjusted with buttons and ⇒page 122, fig. 92 . If
the blower is off (level is not shown on the screen) and button is kept
pressed down, the Climatronic switches off. Then OFF is displayed on the
screen.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air outlets separately.
Switching the air conditioning system on and off
By pressing the button, the air cooling system can be switched off in
order 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.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.– Press the button to switch air recirculation mode on or off. This is ON if the symbol
 ⇒ page 122, fig. 92 is displayed on

Technical Data
When the outside temperature is low, air recirculation mode improves
heating performance by heating air from the interior instead of cold air from
the outside.
When the outside temperature is high, air recirculation mode improves
cooling performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation
should not be switched on when the
air distribution control is being adjusted to the windscreen setting
.
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).
Note
When engaging reverse gear, the air recirculation is connected automatically
to prevent the entrance of exhaust fumes in the vehicle on travelling back-
wards. In this case the symbol for air recirculation is not displayed.General notesThe impurity filter
The impurity filter (a combined particle filter and active carbon filter) serves
as a barrier against impurities in the ambient air, including dust and pollen.
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the specified intervals in the Maintenance Program. 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.
Caution
•If you suspect that the air conditioning is damaged, switch it off with the
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 you to take the vehicle to a qualified
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 puddle
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 th e vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.•The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the vehicle has been over-
heated by sun, the air inside can be cooled quicklier 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.•At low outside temperatures the compressor switches off automatically.
The button cannot be switched on either.

lubricate 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.•To ensure correct operation, the grilles on both sides of the screen must
not be obstructed•When the engine is under extreme strain, switch off the compressor for a
moment.

Starting diesel engines
The engine can only be started using a genuine SEAT key with
its correct code.– Move the gear lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the starter
to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 129, fig. 95 . The
indication lamp
 will light for engine pre-heating.
– When the warning lamp turns off, 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 a very cold engine, it may 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 with starting the engine, see ⇒ page 219.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp 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 after refuelling with diesel fuel. This is
because the system must eliminate air first.
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 avoid high engine speeds, driving at
full throttle and over-loading the engine. Risk of engine damage.•The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.•Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and follow
the instructions in ⇒page 219, “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 the engine off– Stop the engine.
– Turn the ignition key to position ⇒page 129, fig. 95 .

Always apply the handbrake
firmly. This prevents you driving with the hand-
brake applied ⇒ .
The handbrake warning lamp
 lights up when the handbrake is applied
and the ignition is switched on. The warning turns off when the handbrake is
released.
WARNING
•Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied to
the rear wheels. Risk of accident!•If it is only partially released, this will cause rear brakes overheating,
which can impair the function of the brake system and could lead to an acci-
dent. This also causes premature wear on the rear brake pads.Caution
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected.Parking
The handbrake should always be firmly applied when the
vehicle is parked.Always note the following points when parking the vehicle:
– Use the foot brake to stop the vehicle.
– Apply the handbrake.
– The first gear should also be selected. – Switch the engine off and remove the key from the ignition lock.
Turn the steering wheel slightly to engage the steering lock.
– Always take you car 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 towards the kerb .•If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .•Secure the vehicle as normal by applying the handbrake firmly and
engaging first 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 occupants.•Never leave children alone in the vehicle. They could set the vehicle in
motion, for example, by releasing the handbrake or the gear lever /
selector lever.•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.

Intelligent technology
152Electronic Stabilising Program (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
WARNING
•It must be remembered that ESP cannot defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.•Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, this can cause accidents.Caution
•In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.•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 ABS, EDL, ESP and TCS.
Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 150.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 59.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braking wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally 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 accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle's stability.
