Driving
rise in temperature causes the soot on the fil-
t er t
o b
urn. On completion of the cleaning
the warning lamp will switch off.
If the lamp does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
● Alw a
ys drive according to the road weather
conditions, the terrain and traffic.
● The particulate filter attains very high tem-
peratur
es. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammable materials. Risk of fire! CAUTION
While the warning lamp is lit
up, the fuel
consumption is high, and in certain condi-
tions, the engine power is reduced. Note
● In order f or the p
articulate filter to burn off
soot in a correct manner, avoid carrying out
frequent short journeys.
● Using diesel fuel with a high sulphur count
can con
siderably reduce the useful life of the
particulate filter. The specialised service pro- vides information about the countries where
fuel
w
ith a high sulphur content is used. Engine management*
This warning lamp monitors the engine man-
agement
sy
stem for petrol engines.
The warning lamp (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Take the vehi-
cle to a specialised workshop as soon as
possible and have the engine checked.
Emission control system* Control lamp
fla
she
s:
When there is misfiring that can damage the
catalytic converter. Reduce speed and drive
carefully to the nearest specialised workshop
to have the engine checked.
The control lamp lights up:
If a fault has developed during driving which
has reduced the quality of the exhaust gas
(e.g. lambda probe fault). Reduce speed and drive carefully to the nearest specialised
workshop t
o have the engine checked.
Engine pre-heating/fault system* The warning lamp lights up to show that the
glow p
lug
s are preheating the diesel engine.
The control lamp lights up
If the control lamp lights up when the en-
gine is started it means that the glow plugs
are preheating. The engine can be started
straight away when the lamp switches off.
Control lamp flashes
If a fault develops in the engine management
system while you are driving, the glow plug
system lamp will flash . Take the vehicle to
a specialised workshop as soon as possible
and have the engine checked.

Towing bracket device
Driving with a trailer Exterior mirrors
Check
whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Observe the relevant statutory requirements
of the country you are in.
Headlights
Before starting a journey, also check the
headlight beam settings with the trailer
hitched up. Adjust the headlight range set-
tings if necessary ›››
page 117, Main light
range control .
Driving speed
For your own safety do not drive faster than
the maximum permitted speed indicated on
the trailer.
At all times, immediately reduce speed if you
detect the slightest swaying movement of the
trailer. Never try to “return the trailer to a
straight position” by accelerating.
Brakes
Brake in due course! If the trailer has an over-
run brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that
can be caused by locking of trailer wheels.
Change to a lower gear in good time before descending a slope in order to take advant-
age of
the en
gine brake.
The trailer is incorporated into the vehicle's
anti-theft alarm system:
● When the vehicle has a factory-fitted anti-
theft al
arm and a towing bracket.
● When the trailer is electrically connected to
the vehic
le via the towing bracket socket.
● When the vehicle electrical device and the
tow
ing bracket are operational.
● When the vehicle is locked and the vehi-
cle's
anti-theft alarm device is activated.
Once the electrical connection is interrupted
with the vehicle trailer locked, the alarm
sounds.
Always switch off the vehicle anti-theft alarm
device before connecting or disconnecting a
trailer. The vehicle anti-theft alarm device
could cause the alarm to sound ››› page 112,
Anti-theft alarm system*.
Engine overheating
In the event that the coolant temperature
gauge needle moves to the right section of
the scale or to the red area, immediately re-
duce speed. If the control lamp flashes on
the general instrument panel, stop the vehi-
cle and switch off the engine. Wait several
minutes and check the coolant level in the
tank ››› page 208. Please observe the following indications
›››
page 208, Control lamp .
The coolant temperature can be reduced by
switching on the heating. WARNING
● Adjus t
your speed to suit the road and traf-
fic conditions.
● An electrical installation that is connected
incorrectly
or by non-specialised personnel
can prevent the connection of the current to
the trailer and cause faults in the operation of
the electrical system throughout the entire
vehicle, leading to accidents and serious in-
jury.
● All electrical work must be carried out only
by s
pecialised services.
● Never directly connect the trailer electrical
device t
o the electrical sockets of the reverse
driving lights or other sources of electrical
current. CAUTION
● Av oid c
orners, and sudden and sharp brak-
ing.
● Once the trailing arm has been removed,
plac
e the corresponding cover on the hole of
the fastening point. This prevents dirt from
entering the hole – see the trailer system as-
sembly manual. » 185

Care and maintenance
Wheels Wheel trims
If
y
ou wash the vehicle regularly, you should
also thoroughly wash the wheel trim. Regu-
larly remove any brake dust and road salt
from the wheels, otherwise the wheel materi-
al could be damaged. Repair any damage to
the wheel paintwork immediately.
Alloy wheels
After thorough washing, treat the wheels
with a protective product for alloy wheels. Do
not use abrasive products to care for the
wheels. WARNING
Moisture, ice and road salt may affect braking
efficiency . Ri
sk of accident! CAUTION
Heavy dirt on the wheels could lead to their
mis a
lignment. This could result in vibrations
being transmitted to the steering wheel that
under certain conditions may cause prema-
ture steering wear. This dirt must be re-
moved. Note
We recommend you leave paint damage re-
pair s
to a SEAT Authorised Service. Vehicle underbody protection
The underside of the vehicle is coated to per-
manently
pr
otect it from chemical and me-
chanical agents.
Given that damage to the protective coating
during driving cannot be completely ruled
out, we recommend you check the condition
of the protective coating on the underbody
and suspension at regular intervals, prefera-
bly before the start and end of the coldest
season of the year.
Authorised SEAT dealers have suitable spe-
cial products and the necessary facilities and
are aware of the techniques required for their
application. We therefore recommend all
touch-up work or additional anti-corrosion
measures be performed by an authorised
SEAT dealer. WARNING
Do not apply underseal or anti-corrosion
co atin
gs to the exhaust pipes, catalytic con-
verter, particulate filter or heat shields on the
exhaust system. Once the engine has
reached operating temperature, these sub-
stances could catch fire. Risk of fire! Cavity waxing
All cavities on the vehicle exposed to corro-
sion ar
e perm
anently factory-protected by a
wax solution .
This wax solution does not need to be
checked or touched up. Should wax run out
of the cavities at high ambient temperatures,
remove it using a plastic scraper and clean
away any stains using lighter fluid. WARNING
Note the regulations concerning safety and
env ir
onmental protection if you use lighter
fluid to remove the wax. Risk of fire! Leatherette and upholstery
Leatherette can be cleaned with a damp
c
loth. If
thi
s is not sufficient, these parts
should only be cleaned with solvent-free
plastic care and cleaning products .
Textile covers and trim parts on doors, boot
lid, etc. can be cleaned with special deter-
gents, e.g. dry foam. A soft sponge or brush
or a micro-fibre cloth for normal cleaning can
be used. Use special products to clean the
headliner. »

Fig. 203.
– Open the cover in the direction indicated
by
the arr
ow 2 .
– Unscrew the tank cap anti-clockwise and
pl
ac
e it on top of the tank flap ››› Fig. 203
.
– Insert the pump nozzle into the fuel feed
tube as
far as it will go.
The fuel tank is full as soon as the automatic
filler nozzle cuts out ››› .
– Remove the pump nozzle from the fuel feed
tube and p
l
ace it back on the pump.
– Screw the tank cap clockwise until it clicks
into pl
ace.
– Close the tank flap. Make sure you hear it
click
into place.
– Check that the fuel flap is properly closed. WARNING
Observe all relevant statutory regulations on
tran s
porting spare fuel canisters. For safety reasons, we do not recommend carrying a
sp
ar
e canister in the vehicle. The canister
could be damaged in an accident and fuel
may leak. Risk of fire! CAUTION
● Sw itc
h off the auxiliary heater (heater and
independent heater) before filling the tank.
● The fuel tank is full as soon as the automat-
ic fil
ler nozzle cuts out. Do not continue fill-
ing, as this will fill the expansion chamber.
● Never completely empty the tank! An irreg-
ular f
uel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
● If any fuel is spilt onto the paintwork of the
vehicl
e, it should be removed immediately.
Risk of damage to paintwork! Note
There is no emergency mechanism for the
manua l
release of the fuel tank flap. If neces-
sary, request assistance from specialised per-
sonnel. Note
The fuel tank capacity is around 55 litres, of
which 7 litr e
s are the reserve. Types of petrol
The correct grade of petrol is listed inside the
fuel
t
ank 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
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91 oc-
tane 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.
200
Page 203 of 248

Checking and refilling levels
Super unleaded 98 octane or super 95 oc-
t ane u
n
leaded 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 al
l
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 ››› . SEAT recommends “genuine Volkswagen
Gr
oup F
uel
Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef
uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a
y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t
ank flap.
We recommend the use of diesel fuel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel). »

The dipstick shows the engine oil level.
››› Fig. 207.
Checking oil level – Park the vehicle on a level surface and en-
sure the en
gine is at operating tempera-
ture.
– Switch the ignition off.
– Open the bonnet.
– Wait a few minutes for the engine oil to
flow bac
k to the sump and remove the dip-
stick.
– Wipe the dipstick with a clean cloth and in-
sert it
again as far as it will go. –
Then pul
l the dipstick out again and check
the oil level.
It is normal for the engine to consume a cer-
tain amount of oil. Depending on how you
drive and the conditions in which the vehicle
is used, oil consumption can be up to 0.5 li-
tres per 1,000 km. Oil consumption can also
be higher for the first 5,000 km (3000 miles).
You should therefore check the oil level at
regular intervals, ideally every time you fill
the tank or before setting off on a long trip. CAUTION
● The oil l
evel must never exceed area A ›››
Fig. 207. Risk of damage to the exhaust
system!
● If the engine oil cannot be topped up under
the given condition
s, do not drive on! Stop
the engine and seek the professional assis-
tance of an Official Service, as this could
cause serious damage to the engine. Topping up engine oil

Checking and refilling levels
– Re
a
d off the coolant level on coolant ex-
pansion tank ››› Fig. 208. When the engine
is cold, the coolant should be between marks B (min.) and
A (max.). When the
en gine i
s
hot, it may be slightly above mark
A (max.).
If the c
oo
lant fluid level in the reservoir is too
low, this will be indicated by the red warn-
ing lamp illuminating on the general dash
panel ››› page 208, Control lamp . However,
we recommend checking the coolant level di-
rectly in the tank.
Coolant fluid loss
Any loss of coolant normally indicates a leak.
It is not sufficient merely to top up the cool-
ant. The cooling system should be inspected
by an Official Service without delay. CAUTION
● In the event of
a fault that causes the en-
gine to overheat, contact an authorised SEAT
dealer immediately, as this could damage the
engine.
● Anti-freeze that does not correspond to the
correct
specification may particularly affect
corrosion protection considerably.
● Faults caused by corrosion may lead to
cool
ant leaks. Risk of serious engine faults! Topping up the coolant level
–
Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion
tank ›
›› Fig. 208 with a cloth and carefully
unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into
plac
e.
Do not use a different type of additive if the
prescribed anti-freeze additive is not availa-
ble, in the event of an emergency. In this
case, use only water and bring the coolant
concentration back up to the correct level as
soon as possible at an Official Service.
Always top up with unused coolant.
Never fill the coolant tank above mark A (max.)

Fig. 208 Excess coolant is forced
out of the cooling system through the over-
pressure valve in the filler cap of the expan-
sion tank when the engine heats up. WARNING
● The anti-freez e a
dditive and, therefore, the
entire coolant, are a health hazard. Avoid
touching the coolant. Coolant fumes are also
a health hazard. For this reason, always store
the coolant additive in a safe place out of the
reach of children. Risk of poisoning! ●
If s p
lashed into eyes, rinse immediately
with clean water and seek immediate medical
attention.
● Seek immediate medical attention if the
cool
ant is accidentally ingested. CAUTION
If the coolant cannot be topped up under the
giv en c ondition

– Check the brake fluid level in the reservoir
›››
Fig. 209. It should be between the “MIN”
and “MAX” marks.
The fluid level drops slightly after a period of
time due to automatic compensation for
brake pad wear. This is quite normal.
However, if the level goes down noticeably in
a short time, or drops below the “MIN” mark,
there may be a leak in the brake system. If
the brake fluid level in the reservoir is too
low, this will be indicated by the warning
lamp illuminating on the instrument panel
››› page 153, Control lamp .WARNING
● If the fluid l ev
el has dropped below the MIN
mark, do not continue driving. Risk of acci-
dent! Go to a technical service.
● Heavy use of the brakes may cause a va-
pour lock if
the brake fluid is left in the brake
system for too long. This would seriously af-
fect the efficiency of the brakes and the safe-
ty of the vehicle. Changing the brake fluid

In vehicles equipped with a battery with col-
our indicator, the so-called magic eye
››› Fig. 212 changes colour to indicate the
acid level. Air bubbles can influence the colour of the in-
dicator
. Therefore, carefully knock the indica-
tor before checking the acid level.
● Black – the acid level is correct.
● Colourless or light yellow – acid level too
low, b
attery must be changed. Note
● The batt er
y acid level is also regularly
checked during servicing at authorised SEAT
dealers.
● The electrolyte level on “AGM” batteries
cannot be c
hecked for technical reasons.
● Vehicles equipped with the “Start-Stop”
syst
em include a battery control unit to con-
trol the battery level for repeated engine
starting. Winter service
At low temperatures the battery provides only
a fr
action of
the s
tarting power it has at nor-
mal temperatures.
A flat battery can also freeze at temperatures
slightly below to 0°C (32°F).
We therefore recommend you have the bat-
tery checked and, if necessary, charged at an
official SEAT technical service before the start
of winter. Charging the battery A fully-charged battery is essential for relia-
bl
e s
tarting.
– Switch off the ignition and all electrical
equipment.
– For “f
ast-charging” only: disconnect both
batter
y connection cables (first the “nega-
tive” terminal and then the “positive”).
– Connect the charger cables to the battery
terminal
s (red = “positive”, black = “nega-
tive”).
– Plug in the battery charger and switch on.
– After charging the battery: Switch off the
batt er
y charger and disconnect the cable.
– Remove the charger cables.
– If necessary, reconnect both battery cables
to the batt
ery (first the “positive” cable,
then the “negative” cable).
When charging with a low current (e.g. with a
small battery charger ), the battery does not
normally have to be disconnected. The in-
structions of the battery charger manufactur-
er must be followed.
Use a current equivalent to or lower than
10% of the battery capacity to fully charge
the battery.
Before “fast-charging” the battery however,
both battery cables must be disconnected. »

Advice
“Fast-charging” a battery is dan
g erous and
requires a battery charger and special knowl-
edge. Fast charges should be performed by
an official technical service.
The battery caps should not be opened while
the battery is being charged. CAUTION
In vehicles fitted with the “Start-Stop” sys-
tem, the c h
arger cable cannot be directly con-
nected to the negative terminal of the vehicle

We recommend having the vehicle checked by
an authorised S EA
T dealer to guarantee the
correct working order of all electrical sys-
tems. Replacing the battery
A replacement battery must have the same
cap
ac
ity, voltage, current rating and size as
the original. The appropriate types of battery
can be acquired from authorised SEAT deal-
ers.
We recommend having the battery changed
by an authorised SEAT dealer, where the new
battery will be correctly installed and the
original disposed of in line with regulations.
Automatic disconnection of electrical
equipment When heavily-charging a battery, the pro-
gr
amme sel
ect
ed by the electrical system
control unit prevents the battery from auto-
matically discharging. This may result in the
following:
● Increase in idling speed so that the alterna-
tor can s
upply more current to the electrical
system.
● The performance of certain electrical com-
ponents cou
ld be limited or some may switch
off temporarily, e.g. the heated seats, the
heated rear window, the 12 V power socket. Note
Despite any measures taken by the control
unit, the b att
ery could drain. e.g. with the en- gine is switched off, the key is turned in the
ignition for a lon
g period or the s
ide lights or
parking lights are switched on. The switching
off of certain electrical components does not
impair driving comfort and often the driver
will not even notice. 214
