gear if your vehicle has automatic tr
ansmission). 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 208, “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 218,
“Topping up engine oil ”. – Never tow the vehicle to start it, use jump leads if necessary
⇒page 262.
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 73. 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 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.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.

Driving and the environment
192Diesel 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 cle an 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 cont act with flammable materials under-
neath the vehicle. Failure to comply could result in fire.Caution
•
The vehicle is not designed for refuel ling 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 ecological drivingEconomical and environmental 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.
Driving ahead of the circumstances
A vehicle uses most fuel when accele rating. 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 preserves brakes and tyres from wear; the emis-
sions and fuel consumption are reduce d to zero (disconnection out of
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”
position.
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

Trailer towing
196•
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 stored in the tool box.
The ball coupling is provided with in structions 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 removed 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 pr event the jerking that can be
caused by the trailer wheels locking. Se lect 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 moni tor 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.

Your vehicle maintenance and cleaningGeneral notesRegular washing and care help maintain the value of your
vehicle.Your vehicle maintenance
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 corr osion 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 materi als 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 important 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 clea ning 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)

Your vehicle maintenance and cleaning
200Vehicle exterior maintenanceAutomatic 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 u sed, 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.
– Clea n you r vehicle from top to bo ttom with a soft sponge, a g love 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. Ap ply silicone spray to the rubber
seals.
After washing
– Directly after washing, avoid sudden and sharp braking. “Dry” ⇒page 190, “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.

Practical tips
Te c h n i c a l D a t a
•
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 lo ck 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 202.
– Never use concentrated jet nozzles (“rotating jets”) ⇒.
– Directly after washing, avoid sudden and sharp braking. “Dry” ⇒page 190 the brakes by braking several times.
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.

Practical tips
Te c h n i c a l D a t a
– 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 wil
l 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 regula r intervals. If you notice that the
belt webbing, fittings, retractor mechanism or buckle of any of the belts is
damaged, the belt must be repl aced by a specialist workshop.
•
Do not attempt to repair a damaged se at 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
216•
Wait until no more steam, smoke or coolant is emitted from the bonnet,
then carefully open the bonnet.
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 213.
Closing the bonnet– Raise the bonnet slightly
– Release the bonnet stay and replace it in its support.
– At a height of about 30 cm let it fall so it is locked.If the bonnet does not close, do not press downwards. Open it once more and
let it fall as before.
WARNING
If the bonnet is not closed properly, it could open while you are driving and
completely obscure your view of the road. Risk of accident.•
After closing the bonnet, always check that it is properly secured. The
bonnet must be flush with the surrounding body panels.
•
If you notice that the bonnet latch is not secured when the vehicle is
moving, stop the vehicle immediately and close the bonnet properly. Risk
of accident.
Engine oilEngine oil specifications
The engine oil used must conform 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 in stead. 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.

Checking and refilling levels
222•
When the engine is warm or hot, th e cooling system is pressurised! Do
not unscrew the cap on the expansion t ank when the engine is hot. This is
a burn injury risk.Caution
•
When mixed with other additives the colour of G 12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to do
so will result in engine damage!
•
If a lot of coolant has been lost, wait for the engine to cool down before
putting in cold coolant. This avoids damaging the engine. Large coolant
losses are an indication of leaks in the cooling system. See a specialised
workshop immediately and have the cooling system checked. Otherwise,
there is a risk of engine damage.
Washer fluid and windscreen wiper bladesTopping up washer fluid

The water for cleaning the windscreen should always be
mixed with washer fluid.The windscreen washer and the headlight washing system are supplied with
fluid from the windscreen washer flui d container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean the windscreen and headlights. We recom-
mend that you always add a product to the windscreen washer fluid.
Approved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.

Checking and refilling levels
226Brake fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.The position of the brake fluid reservoir is shown in the corresponding engine
compartment diagram ⇒ page 273. The brake fluid reservoir has a black and
yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear. However, if the level goes down noticeab
ly in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low ⇒page 73.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 213.Changing the brake fluid
The Maintenance Program indicates the brake fluid change
intervals.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 213 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the cour se of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also consider ably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
It is important that you use only brake fluid compliant with the US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
