Driving WARNING
The components of the exhaust system reach very high temperatures.
This c
ould cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in cont
act with flammable materials (such as wood, leaves, spilled
fuel, dried grass, etc).
● Do not apply additional underseal or anti-corrosion coatings to the
exhau
st pipes, catalytic converter, heat shields or the diesel particulate
filter. 

Driving WARNING
Cold start sprays could explode or cause a sudden increase in the engine
speed.
● Nev er u
se start boosters. CAUTION
● An attempt to start the engine while driving or starting the engine imme-
di at

ely after turning it off can cause damage to the engine or starter motor.
● When the engine is cold, avoid high revs and heavy acceleration and do
not mak
e the engine work hard.
● Do not push or tow start the engine. Sunburnt fuel could damage the
catalytic
converter. For the sake of the environment
Do not warm the engine at idle speed; start driving immediately if the visi-
bi lity

is OK. This helps the engine reach operating temperature faster and
reduces emissions. Note
● For example, if the key battery is very worn or flat, the engine cannot be
s t

arted with the starter button. In this case, remove the ignition button from
the lock and insert the key.
● Electrical components with a high power consumption are switched off
temporari
ly when the engine starts.
● When the engine is started cold, there may be strong vibrations for a few
moments for t
echnical reasons. This is quite normal, and no cause for con-
cern.
● At temperatures below +5°C (+41°F), smoke may be given off below the
vehicl
e when the additional heater is connected. Stopping the engine Complete operations only in the sequence given:
Step
1. Stopping the vehicle completely
⇒  .
2. Press the brake pedal and keep pressed until step 4 has been
comp
l

eted. 3. In automatic gearboxes, put the selector lever in position
P. 4. Connect the electronic parking brake
⇒ page 183. 5. Turn the key in the ignition lock to position
⇒ fig. 127 0 .
6. With a manual gearbox, put the vehicle in first or reverse gear.
WARNING
Never switch off the engine while the vehicle is moving. You may lose
contr o

l of the vehicle and there is a risk of serious accident.
● The airbags and belt tensioners do not work when the ignition is
switc
hed off.
● The brake servo does not work when the engine is not running. To
stop
, the brake pedal must be pressed with more force.
● As the power steering does not work if the engine is not running, you
wil

l need more strength to steer than normally.
● If the key is removed from the ignition, the steering may lock and it
wil

l not be possible to steer the vehicle. CAUTION
If the engine has been driven at high speed for a prolonged period of time,
it m a

y overheat when turned off. To avoid engine damage, allow the engine
to run for approximately two minutes in neutral before switching it off. Safety First Operating instructions Practical tips Technical Data

Driving and the environment
Other factors which increase fuel consumption (examples):
● Fault in engine management.
● Driving on hills.
● Trailer towing. 
Saving fuel while driving Fig. 155 Fuel consump-
tion in litre
s
per 100 km
at different outside tem-
peratures.
By adopting an economical driving style and anticipating the traffic situa-
tion 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 af-
ter 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
workin
g tem-
perature in order to minimise fuel consumption and emissions. The ambient
temperature has a decisive influence.
fig. 155 shows the difference in consumption for the same journey at +20°C
(+68°F) and at -10°C (+14°F).
Unnecessary short journeys should be avoided. Try to combine trips.
The vehicle uses more fuel in winter than in summer, even when other con-
ditions are the same.
“Warming” the engine is not only forbidden in some countries, but in prac-
tice it is technically superfluous as it is a waste of fuel.
Adjusting type pressures.
Having the correct pressure in your tyres helps to reduce rolling resistance
and, as a result reduces fuel consumption. Increasing the tyre pressure
slightly (+ 0.2 bar / + 3 psi) can help to save fuel.
If you are prepared to accept a slight reduction in comfort, the tyres may be
filled to the pressures recommended for a fully-loaded vehicle. This is also
valid when driving alone without luggage.
When you buy new tyres, make sure they are optimised for minimum rolling
resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils, known as low friction engine
oil, help to reduce fuel consumption. Low friction engine oils reduce the re-
sistance caused by friction in the engine, they flow around the engine more
quickly and efficiently, particularly in cold starts. The effect is particularly
noticeable in vehicles frequently used for short journeys.
Always check the engine oil level and observe service intervals (engine oil
change intervals).
When purchasing engine oil, always observe legal requirements and ensure
that the oil is approved by SEAT. Safety First Operating instructions Practical tips Technical Data

228
Driving and the environment
Avoid carrying unnecessary loads
The lighter the v
ehicle, the more economical and ecological the driving
style. For example, an additional weight of 100 kg will increase fuel con-
sumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads from the vehicle.
Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Option-
al equipment and accessories (such as roof racks or bike carriers) reduce
the aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds. 

Always pay attention to any lit lamps and to the corresponding descriptions
and ins truction

s to avoid damage to the vehicle. Note
While the control lamps ,  or  r
emain lit, there may be engine prob-
lems, fuel consumption may be greater and the engine may lose power. Catalytic converter The catalytic converter permits the subsequent treatment of the exhaust
ga
se

s thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
● Always use unleaded petrol.
● Never run the tank completely dry.
● Do not top up with too much engine oil ⇒ page 279.
● Do not

tow-start the vehicle; use the starter cables ⇒ page 337.
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 Technical
Service. If this happens, unburnt fuel can enter the exhaust system and es-
cape 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 filt
er r

etains these particulates and burns them. To assist the combus-
tion process, SEAT recommends you avoid frequent short trips.
● Always use diesel with a low sulphur content ⇒ page 267.
● Nev

er use petrol or fuel oil.
● Never use biodiesel. However, a blend prepared by the diesel manufac-
turer c
ontaining biodiesel within the limits established by the EN 590
standard may be used ⇒ page 267. Safety First Operating instructions Practical tips Technical Data

Vehicle maintenance and cleaning WARNING
Additional underseal or anti-corrosion products could catch fire due to
the high temper at
ures reached by the exhaust gas system and other en-
gine components.
● Do not apply additional underseal or anti-corrosion products to the
exhau
st pipes, catalytic converters, heat shields or other parts of the ve-
hicle which reach high temperatures. 
Cleaning the engine compartment The engine compartment of any motor vehicle is a potentially hazardous
are
a

⇒ page 275.
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 ⇒  .
If the en gine c

ompartment is very dirty, always take the vehicle to a Techni-
cal Service for professional cleaning. SEAT recommends visiting a Technical
Service.
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 wa-
ter box from outside to the vehicle interior via the heating and air condition-
ing 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.
● Before starting work, please ensure you are familiar with the required
procedur
e and the safety precautions ⇒ page 275.
● SEAT recommends you have this work performed by a qualified deal-
ership. CAUTION
If water is manually poured into the water box (for example, using a high
pre s

sure cleaning appliance), this could cause significant damage to the ve-
hicle. For the sake of the environment
Only wash the engine compartment in areas allocated for this purpose, to
prev ent

dirty water which may be contaminated by oil, grease or fuel, from
entering the drains. In some districts, the engine compartment may not be
washed outside the wash bays provided for this purpose. 
Caring for and cleaning the vehicle interior Introduction The dye from many items of modern clothing (e.g. dark jeans) is not always
solid enough.
Se

at upholstery (material and leather), especially when light-
coloured, may visibly discolour if the dye comes out of clothing (even when
used correctly). This is not an upholstery defect but indicates that the dye in
the item of clothing is not solid enough. Safety First Operating instructions Practical tips Technical Data

Checking and refilling levels WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in tr affic
and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irre
gular especially on slopes.
● If the engine “is choked” or stalls due to lack of or irregularity of the
fuel s
upply, the power steering as well as all of the driver assistance sys-
tems including braking assistance will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid runnin
g out of fuel. CAUTION
● Always pay attention to any lit lamps and to the corresponding descrip-
tion s

and instructions to avoid damage to the vehicle.
● Never 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 ⇒ fig. 162
indic
ates the side of the vehicle on which the tank flap is located. Filling the tank with petrol or diesel Fig. 163 Open tank flap
with t
ank

cap attached to
the holder.
Before refuelling, always turn off the engine, the ignition, mobile tele- phones, aux
iliary heating and keep them off during refuelling.
Unscrewing the tank cap
● The tank flap is at the rear of the vehicle on the right.
● Press the rear of the tank flap to open it.
● Unscrew the tank cap anti-clockwise and insert it in the hole in the tank
flap hing
e ⇒ fig. 163.
Refilling
The correct petrol type for the vehicle is located on a sticker inside the fuel
tank flap ⇒ page 267.
● If the automatic filler nozzle is operated correctly, it will switch itself off
as soon a
s the tank is full ⇒  .
● Do not continue to refuel if it is turned off! Otherwise, this will fill the ex-
pan s

ion chamber and fuel may leak out if the ambient conditions are warm. 

269
Checking and refilling levels
● If, in exceptional circumstances, petrol with a lower octane rating to that
r ec
ommended is used, only use moderate engine speeds and a light throt-
tle. 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.
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
repl
acement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
● Just one full tank of leaded fuel would seriously impair the efficiency of
the catalytic
converter and could damage it. 
Diesel Diesel fuel
Diesel
f

uel 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 serv-
ice intervals ⇒ Booklet Maintenance Programme ⇒  . Your qualified work-
shop wi l

l 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 temper

atures. Furthermore, the exhaust fumes may turn slightly
bluish while the engine is heating. The quantity of exhaust gases will de-
pend on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a fuel filter pre-heater. This en-
sures 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°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.
Whenever there is little fuel in the tank (reserve), the auxiliary heater auto-
matically switches off. WARNING
Never use start boosters. An aerosol start booster could explode or cause
a sud den ri

se in engine speed leading to engine damage and serious in-
jury. Safety First Operating instructions Practical tips Technical Data

272
Checking and refilling levels WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or m a
y cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible. CAUTION
Failure to heed the warning lamps and text messages when they appear
ma y

result in faults in the vehicle. 
Information on AdBlue In vehicles with Selective Catalytic Reduction, a special urea solution (AdBl-
ue) is
inj

ected 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 tem-
perature 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 offici

al supplier. The AdBlue tank holds about 17 litres.
A message will be displayed on the instrument panel around 2400 km be-
fore the next service to indicate that AdBlue must be refilled ⇒ page 273. If
you ignore this message and do not refill, you will be unable to start the en-
gine afterwards ⇒ page 271.
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 ap-
proved by SEAT.
When the indicators  and  light simultaneously, there is a fault. SEAT
recommends visiting the closest qualified workshop.
