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

W ork
in the engine compartment Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids). Al-
ways observe the warnings listed below and
follow all general safety precautions. The en-
gine compartment of the vehicle is a poten-
tially hazardous area
››› . WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place
the lever in neutral; if it has an automatic
gearbox, place the selector lever in position
P.
● Wait for the engine to cool down.
● Keep children away from the engine com-
partment.
● Never spill liquids used for vehicle opera-
tion on the engine compartment, as these
may catch fire (e.g. the antifreeze in coolant). 198

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

Checking and refilling levels
Check the water level in the windscreen
washer reservoir regularly and top up as re-
quired.
The container for the windscreen washer con-
tains the cleaning fluid for the windscreen,
the rear window and the headlight washer
system*.
● Open the bonnet  ››› page 198.
● The windscreen washer reservoir is marked
with the symbol  on the cap.
● Chec k
there is enough windscreen water in
the reservoir.
Recommended windscreen wipers
● For the hottest seasons we recommend
summer G 052 184 A1 for clear glass. Propor-
tions of the mixture in the washer fluid tank:
1:100 (1 part concentrate per 100 parts wa-
ter).
● All year round, G 052 164 A2 for clear
glass. Approximate proportion of the winter
mixture, up to -18°C (0°F): 1:2 (1 part con-
centrate per 2 parts water); otherwise, a 1:4
proportion of mixture in the washer fluid
tank.
Top-up quantities
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer. WARNING
If the water from the windscreen washer does
not contain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contains enough anti-freeze.
● In cold conditions, you should not use the
windscreen washer system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
similar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.
● Use clean water with a window cleaner rec-
ommended by SEAT.
● If necessary, add a suitable antifreeze to
the water in the reservoir. CAUTION
● Do not mix cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely certain that you fill the fluids into the
correct reservoirs. Using the wrong fluids could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
visibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery
General information The battery is located in the engine compart-
ment and is almost
maintenance-free. It is
checked as part of the Inspection Service.
Nevertheless, check the terminals are clean
and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in
exceptional cases. When the battery is dis-
connected, some of the vehicle's functions
are “lost” ( ››› table on page 206). These
functions will require resetting after the bat-
tery is reconnected.
Deactivate the anti-theft alarm* before you
disconnect the battery Otherwise the alarm
will be triggered. »

reduced, and if necessary, the battery should
be charged ››› in Important safety warn-
ings for handling a vehicle battery on
page 206 Important safety warnings for
handling a vehicle battery All work on batteries requires specialist
knowledge. Please refer to a SEAT Official
Service or a workshop specialising in batter-
ies: risk of burns or exploding battery!
The battery must not be opened.
Never try to
change the fluid level of the battery. Other-
wise explosive gas is released from the bat-
tery that could cause an explosion. 
Wear eye protection.

Battery acid is very corrosive and caustic. Wear
protective gloves and eye protection. In the event
of electrolyte splashes, rinse off with plenty of
water.

Fires, sparks, open flames and smoking are pro-
hibited.

The battery should only be charged in a well-ven-
tilated zone. Risk of explosion!

Keep children away from acid and batteries!
WARNING
● When repairing or working on the electrical
system, proceed as follows:
–1. Remove the key from the ignition. The
negative cable on the battery must be
disconnected.
– 2. When the repair is finished, reconnect
the negative pole of the battery. ●
Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Ensure that the vent hose is always connec-
ted to the battery.
● Never use damaged batteries. This could
cause an explosion! Replace a damaged bat-
tery immediately. CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components. Charging the battery
Terminals for charging the battery are fitted
in the engine compartment.

Important: Before you charge the battery
make sure you read the manufacturer's in-
structions for using the battery charger. WARNING
Never charge a battery that has frozen: re-
place battery! Failure to do so may lead to an
explosion. Note
Use only the terminals in the engine compart-
ment to charge the battery. Replacing the battery
The new battery should have the same speci-
fications (amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy
››› page 191.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop. CAUTION
● Some vehicles, for example those with the
Start-Stop system* are fitted with a special
battery (AGM-type or EFB-type battery). If any
other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.
● Make sure that the vent hose is always at-
tached to the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage. ●
The battery holder and clamps must always
be correctly secured.
● Before starting any work on the battery, al-
ways observe the warnings listed under
››› page 206, Important safety warnings for
handling a vehicle battery .
● Do not forget to replace the battery cover-
ings, where applicable. It is a protection for
high temperatures. This in turn extends the
vehicle service life. For the sake of the environment
 Batteries contain toxic substances includ-
in g s

ulphuric acid and lead. They must be
disposed of appropriately and must not be
disposed of with ordinary household waste.
Make sure disconnected batteries cannot tip
over. Sulphuric acid could be spilt! 207

Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam headlights (if they
are switched on).
10.Turn on the heater blower and heated rear window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11. When the engine is running, disconnect
the l e
ads in reverse order to the details
given above.
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 198.
● The b att

ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint on battery). Failure to comply could result in
an explosion.
●
Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow-starting the

Points to observe when tow-starting or tow-
ing away
If you use a tow rope:
Notes for the driver of the towing vehicle
– The tow rope must be taut before you drive
off.
– Release the clutch very carefully when start-
ing the vehicle (manual gearbox), or accel-
erate gently (automatic gearbox).
Driving style
Towing requires some experience, especially
when using a tow rope
. Both drivers should
be f
amiliar with the technique required for
towing. Inexperienced drivers should not at-
tempt to tow.

Advice
Vehicles with towline anchorage
On the right of the rear bumper there is a cov-
er which covers a threaded hole. – Take the towline anchorage out of the vehi-
cle tool set ››› page 220 .
– To r
emove the bumper cover, just press the
upper side of the cover inwards (arrow) and
remo

ve the cover by levering on the lower
››› Fig. 192 side.
– Scr

ew the towline anchorage into the screw
connection as far as it will go ››› Fig. 193
and tighten with the wheel brace.
After use, unscrew the towline anchorage
and put it back in the vehicle tool kit. Replace
the cover on the bumper. The towline anchor-
age should always be kept in the vehicle. WARNING
● If the towline anchorage is not screwed in
as far as the stop, there is a risk of the screw
connection shearing off during towing (acci-
dent risk).
● If your car has a towing bracket, only use
special towing ropes. Risk of accident! CAUTION
In vehicles fitted with a towing bracket, only
use special tow bars to prevent damage to
the ball joint. These tow bars have been spe-
cially approved for use with towing brackets. Tow-starting
As a general rule, tow-starting is not recom-
mended.
– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch the ignition on.
– Once both vehicles are moving, release the
clutch.
– As soon as the engine has started, press
the clutch and move the gear lever to neu-
tral.
If the engine will not start, it is best to try
starting it using the battery of another vehi-
cle ›››
page 223 before attempting to tow
s t

art. You should only try to tow-start the en-
gine if jump starting is not successful. Tow-
starting is an attempt to start the engine via
the movement of the wheels.
When tow-starting a vehicle with a petrol en-
gine
, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter. WARNING
The risk of accidents is high when tow-start-
ing, for example, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
Do not tow vehicles for more than 50 km. Risk
of damage to the catalytic converter. Towing vehicles with a manual
gearbox
Towing is relatively straightforward.
Please observe the relevant instructions
››› page 224.
The v

ehicle can be towed using a tow bar or
tow rope in the normal way, with all four
wheels on the road; it can also be towed with
either the front or rear wheels lifted off the
road. The maximum towing speed is 50 km/h
(30 mph).
To

wing a vehicle equipped with
automatic gearbox Certain restrictions must be observed when
towing your vehicle.
Please observe the relevant instructions
