Checking and refilling levels
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 to 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. –
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 0.1 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 207. 
Disconnecting and connecting the battery
The following functions will either be inoperative or will not work properly
after disconnecting and reconnecting the battery: 

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.
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. 

Fuses
Introduction
All the electrical circuits are protected by fuses.
● Switch off the ignition and the electrical component concerned before
changing a fuse.
● Identify the fuse corresponding to the failed electrical component
⇒ page 211, Fuses in the dash panel, or ⇒ page 214, Changing fuses in
the engine compartment.
● Take the plastic clip from inside the fuse cover, fit it onto the blown fuse
and pull the fuse out.
● Replace the blown fuse (which will have a melted metal strip) with a new
fuse of the same amp rating.
Fuse colour code
ColourMaximum amp rating
light brown5dark brown7,5red10blue15yellow20white25green30
WARNING
Read and follow the warnings ⇒ page 173, Engine compartment before
starting work in the engine compartment.
CAUTION
● Never “repair” a fuse or replace it by fitting a fuse with a higher amp rat-
ing. Risk of fire! This could also cause damage to other parts of the electri-
cal system.
● If a newly replaced fuse blow again when the electrical component con-
cerned is switched on, the electrical system must be checked by an Official
Service as soon as possible.
Note
● It is advisable to always keep spare fuses in the vehicle. The spare fuse
box is available in the range of original SEAT parts.
● One single electrical component could have more than one fuse.
● Several electrical components may be protected by the same fuse. 

Fuses and bulbs
WARNING
● Take particular care when working on components in the engine com-
partment if the engine 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 correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. Other-
wise, a short circuit could occur.
● Switch off the lights and the parking light before changing a bulb.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the rear lights and the turn signals may be temporarily 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 remain misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also in 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 va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface. 
