128Manual 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 126, fig. 98 to or press
t he blo wer co n t rol a nd do wn . The in dicator is switche d o f f .Te m p e r a t u r e
The inside 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°C), 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 126, fig. 98 . 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
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 126, fig. 98 is displayed on
the screen.
Air recirculation mode prevents strong odours in the ambient air from
entering the vehicle interior, for example when passing through a tunnel or in
a traffic jam.
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 set to the windscreen setting

WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioner 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 notesPollution 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 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.
Caution
•If you suspect that the air conditioner is damaged, switch it off with button
to prevent further damage and have it checked by a qualified workshop.
•Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a qualified work-
shop.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 conditioner operates most effectively with the windows and the
sliding/tilting roof* closed. However, if the vehicle has been overheated by
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.•At low outside temperatures the compressor switches off automatically.
The button cannot be switched on either.•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, 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.

Driving
134Starting 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 132, fig. 101 . The
indicator 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 starting the engine, see the ⇒page 222.
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 un ventilated 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 222, “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 vehicle.
– Turn the ignition key to position ⇒page 132, fig. 101 .

Applying the handbrake
– Pull the handbrake lever up firmly ⇒fig. 110 .
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the direc- tion of the arrow ⇒fig. 110 and guide the handbrake lever down
fully ⇒ .Always apply the handbrake as far as it will go in order to prevent you from
driving with the handbrake applied by mistake ⇒.
The handbrake warning lamp
 lights up when the handbrake is applied
and the ignition 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 brake pedal 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.

Intelligent technology
154Electronic Stability Programme (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 152.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.

Safety First
Operating instructions
Practical tips
Technical Data
If you drive with
wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): The brakes should
be “dried” by pressing the pedal to restore full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.•If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.•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 move the selector lever to a lower gear if
your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.•Never let the brakes “slip” 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.•Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.•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 ⇒ page 172, “Technical modifications” instructions.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine oil ⇒page 184, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 222.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 qualified workshop. In general, the exhaust gas warning lamp will
light up when any of the described symptoms occur ⇒page 56. If this
happens, unburnt fuel can enter the exhaust system and escape into the envi-
ronment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!•Never park where the catalytic converter could come into contact with
dry grass or inflammable 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
system. These materials could catch fire when the vehicle is being driven.

Driving and the environment
158
CautionNever fully drain the fuel tank 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.Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.The diesel engine dust filter eliminates most of the soot from the exhaust gas
system. Under normal driving conditions, the filter cleans itself. If the driving
conditions do not allow the filter to clean itself (for example, multiple short
trips) the filter will be obstructed by dust and pollen and the indicator
 for
the diesel engine particulate filter indicator will light up. See section on
Warning Lamps.
WARNING
•The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Failure to comply could result in fire.
Caution
•The vehicle is not designed for refuelling with blends of FAME fuel
(biodiesel) over 7% in accordance with DIN 51628. The diesel particulate
filter is damaged when this blend percentage is exceeded.Economical and environmentally-friendly
drivingGeneral notes
Fuel consumption depends to a large extent on your personal
driving style.Fuel consumption, environmental impact and engine, brake and tyre wear
depend largely on three factors:•Personal driving style•Conditions of use (weather, road surface)•Te chni cal r eq ui re men ts
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%. This section
suggests methods of lessening the impact on the environment and reducing
your operating costs at the same time.Foresight when drivingA vehicle uses most fuel when accelerating. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherev er possible, take

Driving and the environment
162Always brake in due course. If the trailer has an overrun brake, apply the
brakes gently at first and then, firmly. This will prevent the jerking that can be
caused by the trailer wheels locking. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Reheating
At very high temperatures and during prolonged slopes, driving in a low gear
and high engine speed, always monitor the temperature gauge for the
coolant ⇒page 47.
Electronic Stability Programme*
The ESP* system helps to stabilise the trailer in case of skidding or rocking.
