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. 

Keep children away from the battery!
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. 

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. 

setting switch
The tyre pressure monitoring system uses ABS sensors to compare the revo-
lutions and the circumference of each wheel. Should the circumference of
any wheel change, the warning lamp  in the general instrument panel
⇒ page 76 will light up and an audible warning will be heard.
Tyre circumference may change if:
● Tyre pressure is too low
● Tyre structure is damaged ●
Vehicle load not evenly distributed
● Wheels on one axle are subjected to greater load, (e.g. driving with trail-
er, uphill, downhill)
● Snow chains are fitted
● The temporary spare wheel is fitted
● One wheel on the axle has been changed
Basic system settings
Should the tyre pressure change or if one or more wheels are changed or
the position of the wheel on the vehicle is changed, e.g. changing round the
front and rear wheels, or where a warning lamp lights up when driving, the
system must be adjusted as follows:
● Inflate all tyres to the prescribed pressures ⇒ page 197.
● Switch the ignition on.
● Hold the  
⇒ Fig. 135 button down for at least 2 seconds. The warn-
ing lamp  will light up when the button is pressed. The system memory is
also deleted and a new calibration system will begin, which is indicated by
an audible warning before the warning lamp switches off .
● If the warning lamp  remains lit and does not switch off, not even once
the basic setting process is complete, this indicates a fault in the system.
Contact an Official Service.
The warning lamp  lights up
If the pressure on at least one tyre is significantly lower than the pressure
set by the driver, the warning lamp  ⇒ 
will light up.
The warning lamp  flashes
If the warning lamp flashes, there is a fault in the system. Contact a special-
ised service to have it fixed. 

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. 

Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, 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 specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 182
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 ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out 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 amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● 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 avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
● One single consumer could have more than one fuse.
● Several consumers could run over one single fuse. 
