Driving and the environment
190Diesel 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 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 is not designed for refuelling with mixtures of FAME fuel
(biodiesel) over 7% in accordance with DIN 51628. The diesel particle filter is
damaged when this mixture percentage is exceeded.
Economical and environmentally friendly
drivingEconomical and environmentally friendly drivingFuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an econom-
ical driving style and anticipating the traffic situation ahead, you can easily
reduce fuel consumption by 10-15%. Next, we provide you with some tips in
order to help reduce contamination and,at the same time, save money.
As you drive try to anticipate the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero
(disconnection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible. We
recommend that, whenever possible, you change to a higher gear upon
reaching 2,000 rpm.
Automatic gearbox: Accelerate in moderation and avoid the “kick-down” (full
throttle) position.

Practical tips
Technical Data
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum
service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not regularise until having
driven some four kilometres. This is the reason why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases
tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your car will use about 12%
more fuel as a result of the extra wind resistance caused by the roof carrier
even when it is not in use.
Saving electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.

Driving abroadObservationsTo drive abroad, the following must be taken into consideration:•For vehicles fitted with a catalytic converter ensure that unleaded petrol is
available for the journey. See the chapter “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
Centres 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.
To prevent dazzling, you must apply stickers to certain parts of the headlight
lenses. Further information is available in your Authorised Service Centre.
In vehicles with self-directing headlights, the rotation system must previ-
ously be disconnected. To do this, please go to a specialist workshop.

Trailer towing
194•Find out whether special regulations apply to towing a trailer in your
country.Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•By law, the ball coupling must be re moved if a trailer is not being towed
and it obscures the number plate.Driving tipsDriving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution. Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed in
an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of
snaking . Never try to stop the “snaking” by increasing speed.
Always 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 ascents, driving in a low gear
and high engine speed, always monitor the temperature indicator for the
coolant ⇒page 53.
Electronic Stabilisation Program*
The ESP* system makes it easier to stabilise the trailer in case it skids or
swings.

Cleaning and caring for your vehicleGeneral notesRegular washing and care help maintain the value of your
vehicle.Yo u r v e h i c l e m a i n te n a n ce
Regular care and washing help to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of bodywork corrosion or paint defects.
The best way to protect the car against environmental contaminants is to
wash and wax it frequently . The longer substances such as insects remains,
bird droppings, resinous tree sap, road dirt, industrial deposits, tar, soot or
road salt and other aggressive materials remain on the vehicle, the more
damage they do to the paintwork. High temperatures (for instance in strong
sunlight) further intensify the corrosive effect.
After winter, a period when salt is put on the roads, it is impor tant to have the
underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
•Car care products can be toxic. For this, they must always be kept
closed in their original container. Keep them out of the reach of children.
Failure to comply could result in poisoning.•Always read and observe the instructions and warnings on the package
before using car care products. Improper use could damage your health or your vehicle. The use of certain products may produce noxious vapours;
they should be used in well ventilated areas.
•Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and explo-
sion.•Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply your handbrake firmly and remove the key from the
ignition.Caution
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage the
paintwork or the windows of your vehicle. Soak dirt, mud or dust with plenty
of water.
For the sake of the environment
•When purchasing products for your vehicle maintenance, select the ones
which are not harmful to the environment.•The leftovers of the car care products should not be disposed of with ordi-
nary household waste. Observe the disposal information on the package.WARNING (continued)

Cleaning and caring for your vehicle
198Care of the vehicle exteriorAutomatic car wash tunnel
The car can normally be washed without problem in an auto-
matic car wash.The vehicle paintwork is so durable that the car can normally be washed
without problems in an automatic car washing tunnel. However, the paint-
work wear depends to a large extent, on the kind of the car washing tunnel,
the brushes used, its water filtering and the type of cleaning and preservative
products.
Before going through a car wash, be sure to take the usual precautions such
as closing the windows and sunroof. There is nothing to note apart from that.
If the vehicle has special accessories such as spoilers or a roof carrier or two-
way radio aerial, etc., it is advisable to consult the car washing tunnel oper-
ator.
After washing, the brakes could hesitate to respond as the brake discs and
pads could be wet, or even frozen in winter. “Dry” the brakes by braking
several times.
WARNING
Water, ice and salt on the brakes can reduce braking efficiency. Risk of acci-
dent.
Caution
If an automatic car wash tunnel is used, before entering the tunnel, put the
aerial down parallel to the roof and do not tighten to avoid damage.
Washing by handVehicle washing
– First soften the dirt with plenty of water and rinse it off.
– Clean your vehicle from top to bottom with a soft sponge, a glove or a brush. Use very light pressure.
– Rinse the sponge or glove often with clean water.
– Special car shampoo should only be used for very stubborn dirt.
– Clean the wheels, sill panels etc. until last with a different sponge or glove.
– Rinse the vehicle thoroughly with water.
– Dry your vehicle surface gently with a chamois leather.
–When temperature is cold , dry the rubber seals and its surfaces
to prevent them from freezing. Apply silicone spray to the rubber
seals.
After washing
– Directly after washing, avoid sudden and sharp braking. “Dry” ⇒page 188, “Braking effect and braking distance”the brakes by
braking several times.
WARNING
•Wash your car with the ignition switched off.•Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.

•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Caution
•Never remove dirt, mud or dust if the vehicle surface is dry. Never use a
dry cloth or sponge for cleaning purposes. This could scratch the paintwork
or glass on your vehicle.•Washing the vehicle in low temperatures: when washing the vehicle with
a hose, do not direct water into the lock cylinders or the gaps around the
doors, tailgate, or sunroof. Risk of freezing.For the sake of the environment
To protect environment, the car should be washed only in specially provided
wash bays. This prevents toxic, oil-laden waste water entering the sewerage
system. In some districts, washing vehicles outside wash bays is prohibited.
Note
Do not wash the vehicle in direct sunlight.Washing the car with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!– Always observe the instructions for the high-pressure cleaner, particularly those concerning the pressure and the spraying
distance. – Increase the spraying distance
for soft materials and painted
bumpers.
– Do not use a high pressure cleaner to remove ice or snow from windows ⇒page 200.
– Never use concentrated jet nozzles (“rotating jets”) ⇒.
– Directly after washing, avoid sudden and sharp braking. “Dry” the brakes by braking several times ⇒page 188.
WARNING
•Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Caution
•Do not use water hotter than 60°C. This could damage the vehicle.•To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This is
also important for bumpers painted as the paintwork. The closer the nozzle is
to the surface, the greater the wear on the material.Vehicle paint maintenance requirements
Regular waxing protects the paintwork.You need to apply wax to your car if water does not form small drops and run
off the paintwork when it is clean.

– Apply these products very sparingly.
– Then wipe off with a soft, dry cloth.SEAT does everything possible to preserve the genuine qualities of this
natural product. Due to the natural properties of the specially selected hides
employed, the finished leather has a certain sensitivity to grease and dirt, etc.
so a degree of care is required in everyday use and when looking after the
leather.
Dust and grit in the pores and seams can scratch and damage the surface. If
the vehicle is under solar radiation for long periods, the leather should be
protected to prevent it from fading. However, slight colour variations in high-
quality natural leather are normal.
Caution
•Do not use solvents, wax polish, shoe cream, spot removers or similar
products on leather.•To avoid damage, stubborn stains should be removed by a qualified
workshop.Seat belts cleaning
A dirty belt may not work properly.Check all seat belts regularly and keep them clean.
Seat belts cleaning
– Pull the dirty seat belt right out and unroll it.
– Clean the dirty seat belts with a gentle soap solution.
– Allow it to dry. – Do not roll the seat belt up until it is dry.
If large stains form on the belts, it will not retract correctly into the automatic
belt retractor.
WARNING
•Do not use chemical cleaning agents on the seat belts, as this can
impair the strength of the webbing. Ensure that belts do not come into
contact with corrosive fluids.•Check all seat belts condition at regular inter vals. If you notice that the
belt webbing, fittings, retractor mechanism or buckle of any of the belts is
damaged, the belt must be replaced by a specialist workshop.•Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.Caution
After cleaning, allow seat belts to dr y completely before rolling them up.
Otherwise, the belt retractors could become damaged.

Checking and refilling levels
214Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences running behaviour, performance and
service life of the engine. For this reason, you should use good quality petrol
containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒page 208.Biodiesel*The biodiesel fuel must comply with the DIN EN 14.214 (FAME) Standard.•Biodiesel is a methyl ester obtained from rapeseed oil.•DIN is the German abbreviation for “ Deutsches Institut für N ormung e.V.”,
the German standards institute.•EN means European Norm.•FAME is the English abbreviation for “ Fatty Acid Methyl Ester”. Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•The performance of a vehicle using biodiesel maybe somewhat reduced.•Fuel consumption of a vehicle using biodiesel may be slightly higher.•RME fuel is resistant to the cold down to approx. -10°C.•At temperatures below -10°C, we recommend using winter diesel fuel.•Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel in accordance with standard DIN 51628.Caution
•RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.•If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.Note
•In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.•The fuel filter may become clogged when fu el is changed to biodiesel. For
this reason, we recommend you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.•If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.

Engine oilEngine oil specifications
The engine oil used must conf orm with exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of high quality oil is essential for the correct operation of the
engine and its long useful life, when topping up or replacement is necessary
use only those oils that conform to the requirements of the VW standards.
If it is not possible to find oil conforming to the VW standards then oil
conforming to the ACEA or API standards with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.
