WARNING
Reduced visibility through the windows in-
creases the risk of serious accidents.
● Always ensure that all windows are free of
ice and snow, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● The maximum heat output required to de-
frost windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
system, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not required. WARNING
Stuffy or used air will increase fatigue and re-
duce driver concentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air recirculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Switch the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. SEAT rec-
ommends visiting a SEAT Official Service. Note
● When the cooling system is turned off, air
coming from the outside will not be dried. To
prevent fogging of the windows, SEAT recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the button  . The button lamp should light up.
● The maximum heat output required to de-
frost windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over. Adjust using the Easy Connect
system*

Driving
Exhaust gas filtration system Catalytic converter
Applies to vehicles with petrol engine:
the
vehicle must only be used with unleaded pet-
rol, otherwise the catalytic converter will be
irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: the
diesel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h in 4th or 5th gear (auto- matic gearbox: gear S). Maintain the engine
speed at approximately 2,000 rpm. The rise
in temperature causes the soot on the filter
to burn. On completion of the cleaning the
warning lamp will switch off. If the warning
lamp does not switch off, go immediately to a
specialised workshop to rectify the problem.
WARNING
● Because of the high temperatures which
can occur in the exhaust gas control system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the area of the exhaust system: Fire
hazard! Driving through flooded roads
To prevent damage to the vehicle when driv-
ing through water, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edge of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc., the braking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Driving through flooded areas may severely
damage vehicle components such as the en-
gine, transmission, running gear or electrical
system.
● Whenever driving through water, the Start-
Stop system* must be switched off
››› page 148. Note
● Check the depth of the water before enter-
ing the flooded zone.
● Do not stop in the water, drive in reverse, or
stop the engine in any situation.
● Note that vehicles travelling in the opposite
direction may splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). 141Technical specifications

The essentials

Operation
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing . Never try to stop the “snaking” by in-
c r
easing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gen
tly at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 71.
Electronic stability control*
The ESC* system helps to stabilise the trailer
in case of skidding or rocking. Retrofitting a towing bracket*
Fig. 172
Attachment points for towing brack-
et. If a towing bracket is to be fitted after the ve-
hicle is purchased, this must be completed
according to the instructions of the towing
bracket manufacturer.The attachment points for the towing bracket
A are on the lower part of the vehicle.
The distance between the centre of the ball
coupling and the ground should never be
lower than the indicated value, even with a
fully loaded vehicle and including the maxi-
mum drawbar load.

●
Driving with a trailer involves an extra effort
for the vehicle. Therefore, before fitting a
towing bracket, please contact a Technical
Service to check whether your cooling system
needs modification.
● The legal requirements in your country
must be observed (e.g. the fitting of a sepa-
rate control lamp).
● Certain vehicle components, e.g. the rear
bumper, must be removed and reinstalled.
The towing bracket securing bolts must be

Checking and refilling levels
especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Checking and refilling levels
Refuelling Filling the tank Read the additional information carefully
›››  page 31
If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the
fuel tank is “full”. Do not try to put in more
fuel after the nozzle cuts out, as this will fill
the expansion chamber in the fuel tank.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. Further notes on fuel can be found at
››› page 195 .
The c ap
acity of the fuel tank is listed in the
vehicle
technical specifications ›››
page 268. WARNING
Fuel is highly flammable and can cause seri-
ous burns and other injuries.
● Do not smoke when filling the fuel tank or a
canister. Naked flames are forbidden in the
vicinity due to the risk of explosion.
● Observe legislation governing the use,
storage and carrying of a spare fuel canister
in the vehicle.
● For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle. In an accident the canister could be damaged
and could leak.
●
If, in exceptional circumstances, you have
to carry a spare fuel canister, please observe
the following points:
– Never fill fuel into the spare fuel canister
if it is inside or on top of the vehicle. An
electrostatic charge could build up during
filling, causing the fuel vapour to ignite.
Danger of explosion. Always place the
canister on the ground to fill it.
– Insert the filling nozzle as far as possible
into the spare fuel canister.
– If the spare fuel canister is made of met-
al, the filling nozzle must be in contact
with the canister during filling. This
helps prevent an electrostatic charge
building up.
– Never spill fuel in the vehicle or in the
luggage compartment. Fuel vapour is ex-
plosive. Risk of fatal accident! CAUTION
● If any fuel is spilt onto the vehicle, it
should be removed immediately. It could oth-
erwise damage the paintwork.
● Never run the tank completely dry. An irreg-
ular fuel supply could cause misfiring. As a
result, unburnt fuel could enter the exhaust
system and damage the catalytic converter.
● When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en-
gine, the ignition must be switched on for at » 193

WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, engage
the filling mouth correctly. If you can smell
gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
natural gas (LNG), and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
● The filling nozzles of natural gas pumps
can differ in the way they are operated. If you
do not know, ask a qualified employee at the
petrol station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Fuel
Types of petrol The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on
unleaded pet-
rol. The petrol must comply with European
St and
ard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-

llowing titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91
octane unleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible. Super unleaded 98 octane or super 95
octane unleaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available,
in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives 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 unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .

Checking and refilling levels
●
Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
● If working inside the engine compartment,
remember that, even when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury.
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
partment while the engine is running, the ro-
tating components (for example, poly-V belt,
alternator, radiator fan) and the high voltage
ignition system are an additional hazard.
● Observe the following additional warnings
if work on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage. For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop. Note
On right-hand drive vehicles* some of the
containers/reservoirs mentioned below are
located on the other side of the engine com-
partment. Opening the bonnet
Read the additional information carefully
›››  page 10
The bonnet is released from inside the vehi-
cle.
Check that the windscreen wiper arms are
not unfolded. Otherwise the paint may be
damaged.
The bonnet can only be unlocked when the
driver door is open. WARNING
Never open the bonnet if you see steam or
drips of coolant being released from the en-
gine compartment. Failure to comply could
result in burns. Wait until no steam or coolant
can be seen before opening the bonnet. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay before pressing it
back into its support.
– Carefully close the bonnet.
– Press the bonnet down until it locks into
place.
– Make sure that the bonnet catches onto its
clasp. Do not press down too hard › › › .
WARNING
● For safety reasons the bonnet must always
be completely closed when the vehicle is
moving. Therefore, after closing the bonnet,
always check that the locking element is
properly engaged. This is the case if the bon-
net is flush with the adjacent body panels.
● Should you notice that the bonnet is not
safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet. Failure to follow this instruction
could result in an accident. 199

Cooling system Engine coolant specifications The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13°F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents
scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must always
be at
l e
ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would
reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture
of distilled water and, at least, 40 % of the G
13 or G 12 plu

s-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› . The mixture of G
13 with G 12 plus (TL-VW 774 F), G 12 (red) or
G 11 (green-blue) engine coolants will signifi- cantly reduce the anticorrosion protection
and should, therefore be avoided
››› .
WARNING
If there is not enough anti-freeze in the cool-
ant system, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the coolant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
The original additives should never be mixed
with coolants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system. ● If the fluid in the expansion tank is not pur-
ple but is, for example, brown, this indicates
that the G 13 additive has been mixed with
an inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
environment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Topping up coolant
Read the additional information carefully
›››  page 32
Top up coolant when the level is below the
MIN (minimum) mark.
Checking coolant level – Park the vehicle in a horizontal position.
– Switch the ignition off.
– Read off the coolant level on coolant ex-
pansion tank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant – Wait for the engine to cool down.
– Cover the coolant expansion tank cap with
a cloth and carefully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the expansion tank, otherwise you »
