If the function is not deactivated by pressing the button, this will deacti-
vate after approx. 20 min.
Economic use of the air conditioningWhen the air conditioning is switched on, the compressor consumes engine
power and has influence on fuel consumption. Consider the following points
in order to have the system operat ing in the minimum possible time.
•
If the vehicle interior has overheated due to an excessive solar radiation,
it is best to open the windows or doors to allow the hot air to escape.
•
While in motion, the air conditioning should not be switched on if the
windows or the sunroof are open.*
ClimatronicControl switchesThe air conditioning system only works when the engine is running
and the blower is switched on.

Starting the vehicle up hills
–Apply the handbrake.
– With a selected gear, accelerate slowly and at the same time,
release the handbrake.The steeper the slope, the lower the needed gear. This increases the braking
effect of the engine. For example, when driving down a very steep slope in 3rd
gear. If the engine brake effect is not enough, the vehicle will speed up. The
automatic gearbox automatically changes up to prevent the engine over-
revving. Use the foot brake to reduce speed and change into 3rd gear again
using Tiptronic* ⇒ .
Your vehicle has an automatic interlock which prevents the selector lever
from being put into a position for drivi ng forwards or in reverse from positions
P or N if the brake pedal is not depressed.
The ignition key cannot be removed unless the selector lever is in position P.
Warning lamp “Pressing brake pedal”

When the warning lamp next to the sel ector lever lights up, press the brake
pedal. This is necessary when the auto matic gearbox selector lever is moved
out of positions P or N. At the same time, a text message or the instructions
to perform necessary operations may appear on the instrument panel.
WARNING
•
As a driver, you should never leave your vehicle if the engine is running
and a gear is engaged. If you have to leave your vehicle while the engine is
running, you must apply the parking brake and engage parking lock P.
•
If the engine is running and D or R are engaged, you will need to hold
vehicle stopped by depressing the brake pedal. The car would keep on
creeping forward as the power transmission is not fully interrupted even
when the engine is idling.
•
Never accelerate when changing gear or you may cause an accident.
•
Never move the selector lever to R or P when driving. Risk of accident!
•
Before driving down a long, steep slope, it is advisable to reduce speed
and change into a lower gear.
•
If you stop the vehicle up hill, always hold the foot brake strongly
depressed down to stop it from rolling back.
•
Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat and
will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.
•
Never allow the car to roll down a mountain or a slope with the lever in
the N or D position, regardless of the engine is running or not.Caution
•
If you stop the vehicle up hills, do not attempt to stop it from rolling back
by depressing the accelerator when a ge ar has been selected. Otherwise, the
automatic gearbox may overheat causing damage. Pull the handbrake up or
fully depress the brake pedal to prevent the vehicle from rolling away.
•
If you allow the car to roll when the engine is not running, or with the
selector lever in position N, a lack of lubrication in the automatic gearbox will
damage it.WARNING (continued)

Driving
140•
Never move the selector lever to “R” or “P” when driving. Risk of acci-
dent.
•
Before driving down a very steep slope, reduce your speed and shift to
position 1st.
•
Always hold the vehicle on the foot brake if you stop uphills. Otherwise,
the vehicle could roll back.
•
Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat and
will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.WARNING
Never switch the engine off until the vehicle is stationary. You could lose
control of your vehicle. This could cause an accident and serious injury.•
The airbags and belt tensioners do not work when the ignition is
switched off.
•
The brake servo does not work when the engine is not running. You
need more force to stop the vehicle.
•
Power assisted steering does not wo rk when the engine is not running.
That is why it is much more difficult to turn the steering wheel.
•
Never remove the key from the ignition if the vehicle is in motion. The
steering lock could suddenly engage, and you would not be able to steer
the vehicle.
•
Never allow the car to roll downhill with the gear in “N”, regardless of
the engine is running or not.
Caution
If you allow the vehicle to move when the engine is switched off or with the
selector lever in position “N”, take your foot off the accelerator and wait until
the engine starts idling before returning to position “D”.Kickdown feature
The kickdown feature is designed to give maximum accelera-
tion.If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and engine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.•
Be particularly careful when using the kickdown features on slippery
road surfaces. With a fast acceleration , the vehicle could lose traction and
skid.
•
You should use the kickdown feature only when traffic and weather
conditions allow it to be used safely.

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 150Electronic 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 61.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s 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.
•
Always adapt your driving style to su it road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehi cle (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 173The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the
car is accelerating. ⇒page 150

Driving and the environment
154If you drive with wet brakes, for example, after crossing water areas, in heavy
rainfall or even after washing the car, the effect of the brakes is lessened 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 stopes, if brakes are excessively used, they will overheat.
Before driving down a long steep stopes, it is advisable to reduce speed
and change down into a lower gear (o r 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 “rub” 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 as the brake servo does not function.
•
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. Observe the relevant instructions
before purchasing accessories ⇒ page 173, “Technical modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gasses 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 top the reservoir up ⇒page 187,
“Topping up engine oil  ”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 227.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 warning lamp will light
up when any of the described symptoms occur ⇒page 57. If this happens,
unburnt fuel can enter the exhaust system and escape into the environment.
The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!•
Never park where the catalytic convert er 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.

Practical tips
Te c h n i c a l D a t a
Caution
Never 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 unde r some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be solved
by changing to another fuel brand.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. See under Warning
Lights.
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 has not been made to refuel with mixtures of FAME fuel
(biodiesel) over 7%. The diesel particle filter is damaged when the mixture
percentage is exceeded.
Driving abroadObservationsTo drive abroad, the following mu st be taken into consideration:•
For vehicles fitted with a catalytic converter ensure that unleaded petrol is
available for the journey. See the chap ter “Refuelling”. Automobile organisa-
tions will have information about service station networks selling unleaded
fuel.
•
In some countries, it is possible that a vehicle model is sold under condi-
tions where some spare parts are not available or that the Authorised Service
Centre may only carry out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparation of your vehicle and also about necessary maintenance
and repair possibilities.
Adhesive strips for headlightsIf you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
