CAUTION
● Never mix the windscreen washing water with anti-freeze used for the
cooling system or other additives.
● If the vehicle is equipped with a headlight washer system, only mix a de-
tergent that does not damage polycarbonates with the water.
Note
On topping up the fluid, do not move the filter on the container opening, as
this could contaminate the fluid pipes and, therefore, lead to a windscreen
washer malfunction. 

Incorrect handling of the vehicle battery could lead to damage. We therefore
recommend all work on the vehicle battery be performed by an authorised
SEAT dealer.
Always be aware of the danger of injury and scalding as well as the risk of
accident or fire when working on the battery and the electrical system.
Therefore, always observe the warnings and follow all general safety pre-
cautions.
WARNING
● Battery acid is very corrosive, therefore, the battery must be handled
with the utmost care. Wear protective gloves and protect your eyes and
skin when handling batteries. The corrosive fumes in the air irritate and
inflame the respiratory tract and cause conjunctivitis. It corrodes tooth
enamel and causes deep, difficult-to-heal wounds when in contact with
the skin. Repeated contact with diluted acids causes skin disease (in-
flammation, ulcers and fissures). When in contact with water, acids dilute
and develop a great deal of heat.
● Do not tilt the battery, as acid could leak out of the vapour vents. Pro-
tect your eyes with glasses or a protective helmet! Risk of blindness! If
acid should splash into the eyes, rinse the affected eye immediately for
several minutes using clean water. Then seek medical care immediately.
● Neutralize any acid splashes on the skin or clothing with soap solu-
tion as quickly as possible and rinse off with plenty of water. If acid is
swallowed by mistake, consult a doctor immediately.
● Keep children away from the battery.
● Hydrogen is released and a highly explosive mixture of gases is gen-
erated when the battery is under charge. Sparks when disconnecting or
releasing cable terminals with the ignition switched on could also cause
an explosion.
● A short circuit is produced if the battery terminals are bridged, e.g.
using metal objects, cables, etc. Possible consequences of a short cir-
cuit: melting of lead plates, battery explosion and fire, splashing acid. 

WARNING (Continued)
● 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 en-
gine, 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 battery. Risk of explosion and
acid burns! Replace 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 explosion! Replace a damaged
battery immediately.
CAUTION
● Never disconnect the battery when the ignition is switched on, as the
electrical system (electronic components) of the vehicle could be damaged.
When disconnecting the battery from the vehicle electrical system, discon-
nect its negative terminal (-) first. Only then may the positive terminal (+) be
disconnected.
● When connecting the battery, connect the positive terminal (+) first. On-
ly then may the negative terminal (-) be connected. The battery cables must
never be connected to the wrong battery terminals. Risk of burning the elec-
trical installation.
● Make sure the battery acid does not come into contact with the body-
work. Risk of paintwork 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 disposed of according to current local law.
Note
Replace a battery once it is older than 5 years. 
Battery cover

Checking and refilling levels
– The positive terminal (+) of the battery is connected in reverse
order. 
Checking battery acid level
Fig. 130 Battery: Acid
level indicator
We recommend you have the acid level regularly checked at an official tech-
nical service, particularly in the following cases.
● At high outside temperatures.
● On long daily trips.
● Whenever the vehicle is loaded ⇒ page 193, Charging the battery.
In vehicles equipped with a battery with colour indicator, the so-called mag-
ic eye ⇒ Fig. 130 changes colour to indicate the acid level.
Air bubbles can influence the colour of the indicator. Therefore, carefully
knock the indicator 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 au-
thorised SEAT dealers.
● The acid level on “AGM” vehicle batteries cannot be checked for techni-
cal reasons.
● Vehicles equipped with the “START-STOP” system include a battery con-
trol unit to control the battery level for repeat engine starting. 
Winter service
At low temperatures the battery provides only a fraction of the starting pow-
er it has at normal temperatures.
A flat battery can also freeze at temperatures slightly below 0 °C (32 °F).
We therefore recommend you have the battery 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 reliable starting.
– Switch off the ignition and all electrical equipment.
– For “fast-charging” only: disconnect both battery connection ca-
bles (first the “negative” terminal and then the “positive”).
– Connect the charger cables to the battery terminals (red = “pos-
itive”, black = “negative”).
– Plug in the battery charger and switch on. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

194Checking and refilling levels
–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 have to be disconnected. The instructions of the battery
charger manufacturer 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.
“Fast-charging” a battery is dangerous and requires a battery charger and
special knowledge. Fast charges should be performed by an official techni-
cal service.
The battery caps should not be opened while the battery is being charged.
CAUTION
In vehicles fitted with the “START-STOP” system, the charger cable cannot
be directly connected to the negative terminal of the vehicle battery but
must be attached to the engine earthing point ⇒ page 216. 
Disconnecting and connecting the battery
The following functions will either be inoperative or will not work properly
after disconnecting and reconnecting the battery:
effectInstallationSetting the clock⇒ page 60The multifunction display data is deleted⇒ page 61
Note
We recommend having the vehicle checked by an authorised SEAT dealer to
guarantee the correct working order of all electrical systems. 
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 dealers.
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 programme selected by the electrical
system control unit prevents the battery from automatically discharging.
This may result in the following:
● Increase in idling speed so that the alternator can supply more current
to the electrical system.
● The performance of certain electrical components could be limited or
some may switch off temporarily, e.g. the heated seats, the heated rear win-
dow, the 12V power socket. 

195
Checking and refilling levels
Note
Despite any measures taken by the control unit, the battery could drain. e.g.
with the engine 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 the
driver will often not even realise. 

–  Do not drive on! The tyre cannot be sufficiently filled using
the tyre repair kit.
– See professional assistance.
If the tyre pressure is greater than 1.3 bar (18.8 psi / 130 kPa):
– Correct the tyre pressure again to the correct value (see inside
of the fuel tank flap).
– Carefully resume your journey to the nearest specialised work-
shop at a maximum speed of 80 km/h (50 mph). 
Jump-starting
Introduction
If the engine fails to start because of a discharged battery, the battery can
be connected to the battery of another vehicle to start the engine. Suitable
jump leads are required. 

215
Self-help
Both batteries must be rated at 12 Volts. The capacity (Ah) of the booster
battery should not be significantly lower than that of the discharged battery.
Jump leads
The jump leads must be heavy enough to carry the starter current and must
be fitted with insulated battery clamps. Refer to the instructions given by
the manufacturer.
Positive cable – usually red
Negative cable – usually black
WARNING
● A flat battery can also freeze at temperatures slightly below 0 °C
(32 °F). Do not attempt a jump start with a frozen battery – Explosion
hazard!
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 182.
● The non-insulated parts of the battery clamps must not be allowed to
touch. Additionally, the jump lead attached to the positive battery termi-
nal must not touch metal parts of the vehicle. Risk of short circuit!
● Do not connect the negative lead to the negative terminal of the dis-
charged battery. In the event of sparks when starting the engine, the ex-
plosive gas given off by the battery could catch fire.
● Position the jump leads in such a way that they cannot come into con-
tact with any moving 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 bat-
tery. Risk of explosion!
● 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 elec-
trical system.
● The jump leads should be checked in a specialist vehicle battery shop. 

Towing the vehicle
Introduction
Vehicles with manual gearbox can be towed using a towbar or tow-
rope. They can also be towed with either the front or rear wheels
lifted off the road.
Vehicles with automatic gearbox can be towed using a towbar or
towrope. They can also be towed with the front wheels lifted off the 

217
Self-help
road. If the vehicle is towed with the rear wheels lifted off the road
the automatic gearbox will be damaged!
It is easier and safer to tow a vehicle with a towbar. A towrope
should only be used if you do not have a towbar.
Follow the instructions below when towing a vehicle:
Notes for the driver of the towing vehicle
– Engage the clutch very gently when starting to move or on vehi-
cles with automatic gearbox press the accelerator carefully.
– On vehicles with manual gearbox, the towrope must be taut be-
fore driving off.
The maximum towing speed is 50 km/h (31 mph).
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the steering wheel
lock is not engaged and the turn signals, horn and windscreen
wipers and washers can be used.
– Put the gear lever in neutral or move the selector lever to posi-
tion N (automatic gearbox).
The brake servo and power steering only work when the engine is
running. Considerably more effort is required on the brake pedal
and steering wheel when the engine is switched off.
Ensure the towrope remains taut at all times when towing.
CAUTION
● Do not tow-start the engine. Risk of engine damage! In vehicles with a
catalytic converter, unburnt fuel could reach the catalytic converter and
catch fire in it. This could damage and destroy the catalytic converter. Use
the battery from another vehicle for help in starting the engine ⇒ page 215,
Starting the engine.
● If, due to a fault, there is no oil in the gearbox, the car may only be tow-
ed with the driven wheels lifted clear of the road and transported on a spe-
cial vehicle transporter or trailer.
● If normal towing is not possible or if the vehicle is to be towed for further
than 50 km (31 miles), the vehicle must be transported on a special vehicle
transporter or trailer.
● The towrope should be slightly elastic to reduce the loading on both ve-
hicles during towing. It is advisable to use a towrope made of synthetic fibre
or similar material only.
● Do not pull too hard with the towing vehicle and always take care to
avoid jerking the towrope. When towing on a loose surface there is always a
risk of overloading and damaging the anchorage points.
● Attach the towrope or towbar only to the towline anchorages or to the
removable towing bracket ⇒  page 164, or ⇒ page 218.
Note
● We recommend you use the towrope or towbar available in the SEAT
Original Accessories programme from authorised SEAT dealers.
● Towing a vehicle requires some experience. Both drivers should be fa-
miliar with the technique required for towing. Inexperienced drivers should
not attempt to tow away another vehicle or to have their vehicle towed.
● Note the legal regulations concerning towing, particularly those regard-
ing the signalling of the towed and towing vehicle.
● The towrope must not be twisted, as under certain circumstances this
could unscrew the front towline anchorage. 
