WARNING
Turning off the engine while driving will make stopping the vehicle diffi-
cult; this could even result in the loss of control causing an accident with
serious consequences.
xThe assisted braking and steering systems, the airbag system, safety
belts and certain safety equipment are only active while the engine is
running.
xThe engine should only be switched off when the vehicle is at a stand-
still.
WARNING
While the engine is running or starting it could help reduce the risk of
serious injury.
xNever start or leave the engine running in poorly ventilated or closed
spaces. Exhaust gas contains carbon monoxide, a toxic, colourless and
odourless gas. Carbon monoxide can cause people to lose consciousness.
It can also cause death.
xNever leave the vehicle unattended if the engine is running. The vehicle
could move off suddenly or something unexpected could happen resulting
in damage and serious injury.
xNever use start boosters. Cold start sprays could explode or increase
the engine speed unexpectedly.
WARNING
The components of the exhaust system reach very high temperatures. This
could cause a fire and considerable damage.
xAlways park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as wood, leaves, spilled
fuel, dried grass, etc).
xDo not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter, heat shields or the diesel particulate
filter.
WARNING (continued)

Driving and the environment253
Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Some equipment, when connected, increase fuel consumption considerably,
for example:
xAir conditioning cooling system: If the air conditioning system is required
to cool to significantly lower temperatures than the true outside temperature,
it will require a large quantity of energy from the engine. Therefore, we recom-
mend that the selected temperature for the vehicle is not too different to the
outside temperature. It is a good idea to open all the windows of the car
before starting your journey, and to drive a short distance with all the
windows open to allow the vehicle to cool down slightly. Only then should
you close all the windows and switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driving with the windows open
increases fuel consumption.
xSwitch off the seat heating when the seats have warmed up.
xSwitch off the heated rear window and the windscreen heating when the
windows have demisted and are free of ice.
xDo not leave the independent heating switched on when the vehicle is
moving Ÿpage 187.
Other factors which increase fuel consumption (examples):
xFault in engine management.
xDriving on hills.
xTrailer towing.
Saving fuel while driving
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%.
A vehicle uses most fuel when accelerating. By anticipating the traffic situa-
tion ahead, you will brake and therefore accelerate less. Wherever possible,
let the car roll slowly to a stop, for instance when you can see that the next
traffic lights are red.
Avoid short journeys
Fuel consumption is much higher when the engine is cold, immediately after
it has been started. It takes a few kilometres of driving for the engine to warm
up and to normalise consumption.
The engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions. The
ambient temperature has a decisive influence.
fig. 162 shows the difference in consumption for the same journey at +20 °C
(+68 °F) and at -10 °C (+14 °F).

tion in litres per 100 km at

Driving and the environment 256
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
WARNING
Observe traffic regulations when cleaning the diesel particulate filter while
driving.
xOnly carry on driving if visibility, weather, road and traffic conditions so
permit.
xNever endanger your safety or that of other road users.
Caution
Always pay attention to any lit lamps and to the corresponding descriptions
and instructions to avoid damage to the vehicle.
Note
While the indicators ¬, B or %0# remain lit, there may be engine problems,
fuel consumption may be greater and the engine may lose power
Catalytic converter
The catalytic converter permits the subsequent treatment of the exhaust
gases thus reducing contaminating gas emissions. To ensure a longer
working life for the exhaust system and catalytic converter in a petrol engine:
xAlways use unleaded petrol.
xNever run the tank completely dry.
xDo not top up with too much engine oil Ÿpage 309.
xDo not tow-start the vehicle; use the starter cables Ÿpage 371.If you should notice misfiring, uneven running or loss of power when the car
is moving, reduce speed immediately. Have the car inspected by a qualified
workshop. If this happens, unburnt fuel can enter the exhaust system and
escape into the atmosphere. The catalytic converter can also be damaged by
overheating.
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 being used.
Diesel particulate filter
The diesel particulate filter removes soot particulates from the exhaust gas.
The filter retains these particulates and burns them. To assist the combustion
process, SEAT recommends you avoid frequent short trips.
xAlways use diesel with a low sulphur content Ÿpage 297.
xNever use petrol or fuel oil.
xNever use biodiesel. However, a blend prepared by the diesel manufac-
turer containing biodiesel within the limits established by the EN 590
standard may be used Ÿpage 297.
xNever run the tank completely dry.
xDo not top up with too much engine oil Ÿpage 309.
xDo not tow-start the vehicle; use the starter cables Ÿpage 371.
In order to reduce blocking of the diesel particulate filter, some vehicles with
an automatic gearbox may increase the engine speed slightly to automati-
cally start cleaning the diesel particulate filter. The warning lamp will not light
up in this case
¬.

Vehicle maintenance and cleaning 276
Before applying the product, use a soft cloth to remove dust and dirt from the
rubber seals.
De-icing the door lock cylinder
To de-ice the lock cylinders, SEAT recommend the use of genuine SEAT spray
with lubricating and anti-corrosive properties.
Caution
The use of products containing degreasing agents to de-ice the locks may
rust the lock cylinder.
Protection of vehicle undercarriage
The vehicle underbody is coated to protect it from chemical and mechanical
damage. The protective coat on the undercarriage may wear through use
while driving. Therefore, SEAT recommends that the protective coating on the
undercarriage and on the running gear should be regularly checked, and
repaired if necessary.
WARNING
Additional underseal or anti-corrosion products could catch fire due to the
high temperatures reached by the exhaust gas system and other engine
components.
xDo not apply additional underseal or anti-corrosion products to the
exhaust pipes, catalytic converters, heat shields or other parts of the
vehicle which reach high temperatures.
Cleaning the engine compartment
The engine compartment of any motor vehicle is a potentially hazardous area
Ÿpage 304.
The engine compartment should only be cleaned by qualified personnel. If it
is not correctly cleaned, the anti-corrosion coating and consequently elec-
trical components may be damaged. Moreover, water may filter directly into
the vehicle interior through the water chamber Ÿ.
If the engine compartment is very dirty, always take the vehicle to a qualified
workshop for professional cleaning. SEAT recommends visiting a qualified
workshop.
Water box
The water box is in the engine compartment, between the windscreen and the
engine, and beneath a perforated cover. Air is taken in through the water box
from outside to the vehicle interior via the heating and air conditioning
system.
Leaves and other loose objects should be regularly cleaned away from the
water box either by hand or with a vacuum.
WARNING
When working on the engine or in the engine compartment, there is a risk
of injury, burns, accident or fire.
xBefore starting work, please ensure you are familiar with the required
procedure and the safety precautions Ÿpage 304.
xSEAT recommends you have this work performed by a qualified dealer-
ship.
Caution
If water is manually poured into the water box (for example, using a high pres-
sure cleaning appliance), this could cause significant damage to the vehicle.

WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
xIf the fuel level is too low then the fuel supply to the engine can become
irregular especially on slopes.
xIf the engine “is choked” or stalls due to lack of or irregularity of the
fuel supply, the power steering as well as all of the driver assistance
systems including braking assistance will stop working.
xAlways refuel when there is only one quarter of the fuel tank left to
avoid running out of fuel.
Caution
xAlways pay attention to any lit lamps and to the corresponding descrip-
tions and instructions to avoid damage to the vehicle.
xNever run the tank completely dry. An irregular fuel supply may lead to
ignition faults and unburnt fuel could enter the exhaust system. This could
damage the catalytic converter filter or the diesel particulate filter!
Note
The arrow next to the fuel pump symbol on the instrument panel Ÿpage 294,
fig. 169 indicates the side of the vehicle on which the tank flap is located.
Filling the tank with petrol or diesel
Before refuelling, always turn off the engine, the ignition, mobile telephones,
auxiliary heating and keep them off during refuelling.
Unscrewing the tank cap
xThe tank flap is at the rear of the vehicle on the right.
xPress the rear of the tank flap to open it.
xUnscrew the tank cap anti-clockwise and insert it in the hole in the tank
flap hinge Ÿfig. 170.
Refilling
The correct petrol type for the vehicle is located on a sticker inside the fuel
tank flap Ÿpage 297.
xIf the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is full Ÿ.
xDo not continue to refuel if it is turned off! Otherwise, this will fill the
expansion chamber and fuel may leak out if the ambient conditions are warm.
Fig. 170 Open tank flap

the holder.

Checking and refilling levels 298
If good quality petrol with additives is not available or engine problems arise,
the necessary additives must be added when refuelling.
Not all petrol additives have been shown to be effective. The use of unsuit-
able petrol additives could damage the engine. These additives are available
from qualified workshops, who will inform you of their application.
Caution
xOnly use fuel with an octane rating that is in line with the norm EN 228,
otherwise significant damage could be caused to the engine and fuel system.
Furthermore, it could lead to a loss of performance with the consequent
engine fault.
xThe use of unsuitable petrol additives could damage the engine.
xIf, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throttle.
Avoid using full throttle and overloading the engine. Otherwise you may
damage the engine. Fill up with fuel of a suitable octane rating as soon as
possible.
xDo not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
xJust one full tank of leaded fuel would seriously impair the efficiency of
the catalytic converter and could damage it.
Diesel
Diesel fuel
Diesel fuel must correspond to European standard EN 590 (In Germany, EN
590 or DIN 51628).
The use of diesel fuel with a high sulphur percentage requires shorter service
intervals ŸBooklet “Maintenance Programme” Ÿ. Your qualified work-shop will be able to tell you which countries have diesel with a high sulphur
content.
Do not mix fuel additives (thinners, or similar additives) with diesel fuel.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0 °C (+32 °F) because the fuel thickens due to wax sepa-
ration. For this reason, “winter-grade diesel fuel” is available in Germany, for
example, during the cold months. It can be used at temperatures as low as
-20 °C (-4 °F).
In countries with different climatic conditions, other types of diesel fuel are
available that are suitable to local temperatures. SEAT qualified workshops
and filling stations in the country concerned will inform you on the type of
diesel fuels available.
A cold diesel engine makes more noise during winter temperatures than
summer temperatures. Furthermore, the exhaust fumes may turn slightly
bluish while the engine is heating. The quantity of exhaust gases will depend
on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a fuel filter pre-heater. This
ensures that the fuel system remains operational to approx. -24 °C (-11.2 °F),
provided you use winter-grade diesel which is safe to -15 °C (+5.00 °F).
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C (-11.2 °F), simply place the vehicle in a warm
garage or workshop for a while to heat up.
Auxiliary heater
Vehicles with a diesel engine may be fitted with an auxiliary heater. The
heater runs off the fuel from the fuel tank. On doing so, smells and steam may
be noticed outside the vehicle for a short period. This is normal and it is not
an indication of a fault in the vehicle.

WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
xNever ignore the warning lamps or text messages.
xStop the vehicle safely as soon as possible.
Caution
Failure to heed the warning lamps and text messages when they appear may
result in faults in the vehicle.
Information on AdBlue
In vehicles with Selective Catalytic Reduction, a special urea solution
(AdBlue) is injected into the exhaust gas system in front of the catalytic
converter to reduce nitrogen oxide emissions.
The consumption of AdBlue depends on individual driving style, the temper-
ature at which the system operates and the outside temperature where the
vehicle is driven.
AdBlue is kept in an independent tank in the vehicle and should be refilled at
an official supplier. The AdBlue tank holds about 17 litres.
A message will be displayed on the instrument panel around 2400 km before
the next service to indicate that AdBlue must be refilled Ÿpage 302. If you
ignore this message and do not refill, you will be unable to start the engine
afterwards Ÿpage 300.
SEAT recommends contacting a specialist workshop. If you are unable to visit
a qualified specialist workshop, you should temporarily refill with a minimum
of 10.0 litres of AdBlue. Only refill using AdBlue expressly approved by SEAT.When the indicators
b and > light simultaneously, there is a fault. SEAT
recommends visiting the closest qualified workshop.

xStop the engine and wait a few minutes for the oil to drain back into the
sump. When the engine has cooled down, immediately check the oil level and
top up if necessary.
xOpen the bonnet ’ Ÿpage 304.
xThe engine oil filler opening can be recognised by the symbol E on the
cap Ÿpage 310, fig. 176 and the dipstick by its coloured handle.
Checking the engine oil level
xPull out the dipstick and wipe it on a clean cloth.
xReplace the dipstick, pushing it in as far as it will go. If the dipstick has a
mark, when you reintroduce it this mark should slot into the corresponding
groove located on the upper end of the tube.
xRemove the dipstick again and check the engine oil level Ÿtable on
page 311.
xAfter reading the oil level, replace the dipstick in the tube completely.
Engine oil topping up ranges
Adding oil after checking the level
Only add engine oil in small quantities and in steps.
xUnscrew the cap from engine oil filler opening on the cylinder head
Ÿpage 310, fig. 176. If you are not sure where the cap is, request help from
a specialist.
xOnly refill using engine oil expressly approved by SEAT and in small quan-
tities (not more than 0.5 L or 1/2 a quarter of a gallon at a time) Ÿpage 310.
xTo avoid adding too much oil, each time you add a quantity, wait until the
oil has flowed into the crankcase so that it can be measured with the dipstick.
xCheck the oil level before adding any more oil. Do not top up with too
much engine oil Ÿ.
xWhen the oil level is in at least the Ÿpage 310, fig. 175 zone, insert
the dipstick into the tube fully to avoid engine oil escaping when the engine
is running.
xAfter topping up the oil, ensure that the cap is screwed on to the filler
mouth correctly.
WARNING
Oil could catch fire if it comes into contact with hot engine components.
This could lead to a fire, explosion and severe injuries.
xAlways ensure that after topping of oil, the engine oil filler cap is
correctly tightened. This will avoid engine oil spilling onto hot engine parts
when the engine is running.
Caution
xIf the oil level is above the area Ÿpage 310, fig. 175 do not start the
engine. You should obtain professional assistance. Otherwise catalytic
converter and engine damage may occur.
xWhen refilling or changing service liquids, ensure that you put the liquids
into the right tank. Making a mistake when refilling could cause serious
malfunctions and damage the engine!
For the sake of the environment
The oil level must never be above area Ÿpage 310, fig. 175 . Otherwise
oil can be drawn in through the crankcase breather and escape into the
atmosphere via the exhaust system.
page 310,
fig. 175Operations required depending on the engine oil topping
up level:
Area Do not top up oil Ÿ.
Area Add approximately 0.5 L of oil (1/2 quarter of a gallon). The
oil level can be in the zone , but never above .
Area :
It is essential to add oil (approximately 1 litre or quarter of
a gallon). Ensure that the level is around the centre of the
zone after adding oil.
