● Switch off the auxiliary heater (heater and
independent heater) before filling the tank.
● The fuel tank is full as soon as the automat-
ic filler nozzle cuts out. Do not continue fill-
ing, as this will fill the expansion chamber. Note
The fuel tank capacity is around 55 litres, of
which 7 litres are the reserve. Unleaded petrol
Your vehicle must only be run on
unleaded
petrol that complies with the Standard EN
228 (in Germany, also DIN 51626 – 1, or E10
for unleaded petrol with 95 and 91 octane
rating (RON) or DIN 51626 – 2, or E5 for un-
leaded petrol with 95 and 98 RON).
Prescribed fuel – unleaded petrol (95/91
RON)
Use unleaded petrol with 95
RON. Unleaded
petrol with 91 RON can also be used, al-
though thi s
will result in a slight loss of pow-
er.
If, as an emergency measure, you have to fill
the tank with petrol with a lower RON to that
prescribed, use only moderate engine
speeds and light throttle. High engine speed
and full throttle can seriously damage the en-
gine! Fill up with petrol with the correct RON
as soon as possible.
Prescribed fuel – unleaded petrol (min. 95
RON)
Use unleaded petrol with 95 RON.
If u

nleaded petrol with 95 RON is not availa-
bl

e, you can fill up with petrol with 91 RON as
an emerg
ency measure. In this case, use only
moderate engine speeds and a light throttle.
High engine speed and full throttle can seri- ously damage the engine! Fill up with petrol
with the correct RON as soon as possible.
Petrol with a RON below
91 cannot be used,
even a

s an emergency measure. Risk of seri-
ously damaging the engine!
Unleaded petrol with higher RON
Unleaded petrol with a higher RON to that
prescribed can be used without limits.
In vehicles running on prescribed unleaded
petrol with 95/91 RON
, there is no notable
increase in power or lower fuel consumption
when petrol with a RON higher than 95
is
used.
In vehicles running on prescribed unleaded
petrol with min. 95 RON
, there is an increase
in power and a lower fuel consumption when
petrol with a RON higher than 95
is used.
Prescribed fuel – unleaded petrol (98/(95)
RON)
Use unleaded petrol with 98
RON. Unleaded
petrol with 95 RON can also be used, al-
though this will result in a slight loss of pow-
er.
If unleaded petrol with 98
or 95 RON is not
available, you can fill up with petrol with 91
RON as an emergency measure. In this case,
use only moderate engine speeds and a light
throttle. High engine speed and full throttle
can seriously damage the engine! Fill up with

Advice
Checking coolant level Fig. 112
Engine compartment: coolant fluid
tank. The coolant expansion tank is located in the
engine compartment of the vehicle.
– Switch the ignition off.
– Open the bonnet ››› page 132.
– Read off the coolant level on coolant ex-
pansion tank ››› Fig. 112 . When the engine
i s
cold, the coolant should be between
marks B (min.) and
A (max.). When the
engine is hot, it may be slightly above mark A (max.).
If the coolant 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 35, Coolant level and tempera-
ture  . However, we recommend checking
the coolant level directly 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 engine
to overheat, contact an authorised SEAT deal-
er immediately, as this could damage the en-
gine. Topping up coolant
–
Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion
tank ›››
Fig. 112 with a cloth and
carefully
u

nscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into
place.
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. 112 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-freeze additive 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 splashed into eyes, rinse immediately
with clean water and seek immediate medical
attention.
● Seek immediate medical attention if the
coolant is accidentally ingested. CAUTION
If the coolant cannot be topped up under the
given conditions,  do not drive on. We rec-
ommend c

ontacting an authorised SEAT deal-
er, as this can damage the engine. 138

Checking and refilling levels
Brake fluid Checking brake fluid level Fig. 113
Engine compartment: brake fluid
reservoir. The brake fluid reservoir is located in the en-
gine compartment of the vehicle.
– Switch the ignition off.
– Open the bonnet ››› page 132.
– Check the brake fluid level in the reservoir
››› Fig. 113 . It should be between the “MIN”
and “MAX” m ark
s.
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 33, Brake system  . WARNING
If the fluid level has dropped below the MIN
mark,  do not continue driving. Risk of acci-
dent! Go t
o a technical service. Changing the brake fluid
Brake fluid absorbs moisture. Therefore, it
gradually absorbs moisture from the atmos-
phere. If the water content in the brake fluid
is too high, the brake system could corrode.
The water content also reduces the boiling
point of the brake fluid.
The brake fluid must comply with one of the
following standards or specifications:
● VW 50114
● FMVSS 116 DOT4 WARNING
Heavy use of the brakes may cause a vapour
lock if the brake fluid is left in the brake sys-
tem for too long. This would seriously affect
the efficiency of the brakes and the safety of
the vehicle. CAUTION
Brake fluid damages the vehicle paintwork. Windscreen washer

Checking and refilling levels
●
Neutralize any acid splashes on the skin or
clothing with soap solution as quickly as pos-
sible and rinse off with plenty of water. If acid
is swallowed by mistake, consult a doctor im-
mediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explo-
sive mixture of gases is generated when the
battery is under charge. Sparks when discon-
necting or releasing cable terminals with the
ignition switched on could also cause an ex-
plosion.
● A short circuit is produced if the battery ter-
minals are bridged, e.g. using metal objects,
cables, etc. Possible consequences of a short
circuit: melting of lead plates, battery explo-
sion and fire, splashing acid.
● The following is forbidden while working on
the battery: fire and open flames, smoking
and activities that could produce sparks.
Avoid causing sparks when handling cables
or electrical apparatus. Risk of injury in the
event of large sparks.
● Before working on the electrical system,
you must switch off the engine, the ignition
and all electrical components and disconnect
the cable from the negative terminal (-) of the
battery. To change a bulb, simply switch off
the corresponding light.
● Never charge a frozen or thawed out bat-
tery. Risk of explosion and acid burns! Re-
place a frozen battery.
● Never use the jump leads on batteries in
which the electrolyte level is too low. Risk of
explosion and acid burns! ●
Never use a damaged battery. Risk of ex-
plosion! Replace a damaged battery immedi-
ately. CAUTION
● Never disconnect the battery when the igni-
tion is switched on, as the electrical system
(electronic components) of the vehicle could
be damaged. When disconnecting the battery
from the vehicle electrical system, disconnect
its negative terminal (-) first. Only then may
the positive terminal (+) be disconnected.
● When connecting the battery, first connect
the positive terminal (+) and then the nega-
tive terminal (-). The battery cables must nev-
er be connected to the wrong battery termi-
nals. Risk of burning the electrical installa-
tion!
● Make sure the battery acid does not come
into contact with the bodywork. Risk of paint-
work damage.
● Do not expose the battery to direct sunlight
to protect it from ultraviolet radiation.
● If the vehicle is not used for 3 or 4 weeks,
the battery could run flat. This is because
some components use electricity even in
standby mode (e.g. control units). Prevent the
battery from running flat by disconnecting its
negative terminal or leave it charging at a low
current.
● If you frequently use the vehicle for short
trips, the battery may not fully charge and
could run flat. For the sake of the environment
A flat battery is particularly harmful waste for
the environment. It must therefore be dis-
posed of according to current local law. Note
Replace a battery once it is older than 5
years. Open the battery cover.

Checking battery acid level Fig. 116
Battery: Electrolyte level indicator. We recommend you have the acid level regu-
larly checked at an official technical service,
particularly in the following cases.
● At high outside temperatures.
● On long daily trips.
● Whenever the vehicle is loaded
››› page 142, Charging the battery .
In v
ehicles equipped with a battery with col-
our indicator, the so-called magic eye
››› Fig. 116
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, battery must be changed. Note
● The battery acid level is also regularly
checked during servicing at authorised SEAT
dealers.
● The electrolyte level on “AGM” batteries
cannot be checked for technical reasons.
● Vehicles equipped with the “Start-Stop”
system 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 fraction of the starting 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-
ble starting.
– Switch off the ignition and all electrical
equipment. –
For “fast-charging” only: disconnect both
battery connection cables (first the “nega-
tive” terminal and then the “positive”).
– Connect the charger cables to the battery
terminals (red = “positive”, black = “nega-
tive”).
– Plug in the battery charger and switch on.
– After charging the battery: Switch off the
battery charger and disconnect the cable.
– Remove the charger cables.
– If necessary, reconnect both battery cables
to the battery (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 b
attery cables must be disconnected.
“Fast-charging” a battery is dangerous 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.

Checking and refilling levels
CAUTION
In vehicles fitted with the “Start-Stop” sys-
tem, the charger cable cannot be directly con-
nected to the negative terminal of the vehicle
battery but must be attached to the engine
ground point ››› page 158. Disconnecting and connecting the
battery
The following functions will either be inoper-
ative or will not work properly after discon-
necting and reconnecting the battery:FunctionInstallation

page 32
The multifunction display data
is deleted››› page 39 Note
We recommend having the vehicle checked by
an authorised SEAT dealer to guarantee the
correct working order of all electrical sys-
tems. Changing the battery
A replacement battery must have the same
capacity, 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-
gramme selected 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 supply more current to the electrical
system.
● The performance of certain electrical com-
ponents could 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 battery could drain. e.g. with the en-
gine is switched off, the key is turned in the
ignition for a long period or the side 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. 143

Jump-starting Introduction If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine. Suitable jump leads are required.
Both batteries need to have nominal voltage
of 12 V. The
capacity (Ah) of the back-up bat- t
er
y should not be notably less than the
drained battery.
Jump leads
The jump leads must be heavy enough to car-
ry the starter current and must be fitted with
insulated battery clamps. Refer to the instruc-
tions given by the manufacturer.
Positive cable – usually red
Neg

ative cable
– usually black WARNING
● A flat battery can also freeze at tempera-
tures slightly below to 0 °C (32 °F). Do not at-
tempt to start the vehicle with a frozen bat-
tery. Risk of explosion!
● Please note the safety warnings referring to
working in the engine compartment
››› page 132.
● The non-in s

ulated parts of the battery
clamps must not be allowed to touch. Addi-
tionally, the jump lead attached to the posi-
tive battery terminal must not touch metal
parts of the vehicle. Risk of short circuit!
● Do not connect the negative lead to the
negative terminal of the discharged battery.
In the event of sparks when starting the en-
gine, the explosive gas given off by the bat-
tery could catch fire.
● Position the jump leads in such a way that
they cannot come into contact with any mov-
ing parts in the engine compartment. ●
Do not bend over the battery. Risk of acid
burns!
● The screw plugs on the battery cells must
be screwed in firmly.
● Keep sources of fire (flames, lit cigarettes,
etc.) away from the battery. - Risk of explo-
sion!
● Never use the jump leads on batteries in
which the electrolyte level is too low. Risk of
explosion and acid burns. Note
● The vehicles must not touch each other, as
electricity could flow as soon as the positive
terminals are connected.
● The discharged battery must be properly
connected to the vehicle electrical system.
● The jump leads should be checked in a spe-
cialist vehicle battery shop. 157

Fuses Introduction Due to the constant updating of vehicles,
fuse assignments based on equipment and
the use of the same fuse for various electrical
components, it is not possible to provide an
up-to-date summary of the fuse positions for
the electrical components at the time this
manual was printed. For detailed information
about the fuse positions, please consult a
technical service.
In general, a fuse can be assigned to various
electrical components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment
››› page 132 . WARNING
The high voltages in the electrical system can
give serious electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion system.
● Take care not to cause short circuits in the
electrical system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a current circuit without fuses can
cause a fire and serious injury.
● Never use a fuse with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or similar. CAUTION
● To prevent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse, you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entry of dust or humidity as they can
damage the electrical system. » 163

Introduction Changing bulbs requires a certain degree of
practical skill. If in doubt, we recommend you
have defective bulbs changed by a special-
ised service or, in case of an emergency,
seek professional assistance.
●
Switch off the ignition and all of the lights
before changing a bulb.
● Do not touch the glass part of the bulb with
your bare hands. The fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, reducing bulb life and
causing condensation on the reflector sur-
face, thus reducing effectiveness.
● A bulb must only be replaced by one of the
same type. The type is indicated on the bulb,
either on the glass part or on the base.
● There is a storage area for the bulb box in
the spare wheel well or below the carpet in
the luggage compartment. The light source used for each function is lis-
ted below:

W5W Long Life PY21W NA P21W Super Long Life WARNING
● Take particular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glass can break when you touch the bulb,
causing injury.
● The high voltage element of gas discharge
bulbs* (xenon light) must be handled correct-
ly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not
to injure yourself on sharp parts in the head-
light housing. CAUTION
● Remove the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before changing a bulb. Dipped beam:
Main beam:
Side lights:
Turn signals:
Daytime driving lights: For the sake of the environment
Please ask your specialist retailer how to dis-
pose of used bulbs in the proper manner. Note
● Depending on weather conditions (cold or
wet), the front lights, the fog lights, the rear
lights and the turn signals may be temporari-
ly misted. This has no influence on the useful
life of the lighting system. By switching on
the lights, the area through which the beam
of light is projected will quickly be demisted.
However, the edges may continue to be mis-
ted.
● Please check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bare hands, use a cloth or paper towel
instead. Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat
generated by the bulb, they will be deposited
on the reflector and damage its surface. 166
