Seats and storage
Heated front seats
Fig. 72 Heated front
seats
The cushion and backrest of the front seats can be heated electri-
cally.
Press the 
or  ⇒ 
Fig. 72 button to switch on and adjust the
heated front seats.
Press once to connect the heating at maximum force.
Press the button again to reduce the force of the heating and
switch it off. The force is indicated by the number of warning lamps
lit on the button.
WARNING
Do not use the heated seat if your perception of pain and/or temperature
or that of your passenger is limited, e.g. due to medication, paralysis or
chronic illness (e.g. diabetes). It could cause burns on the back, buttocks
and legs that are difficult to heal. If you still want to use the heated seat,
take frequent breaks on long journeys so that the body can recover from
the trip. Ask you doctor about your particular situation.
CAUTION
● To avoid damaging the heating elements, do not kneel on the seat or
apply sharp pressure at a single point to the seat cushion or backrest.
● Do not use the heated seats if nobody is sitting on them or if there are
items attached to or lying on them, such as a child seat or a bag, etc. This
could lead to a fault in the seat heating elements.
● Do not clean the seats with liquid ⇒ page 169.
Note
● Only connect the heated seats when the engine is running. This pro-
vides considerable savings on the battery capacity.
● In the event of a drop in voltage in the onboard systems, the heated
seats switch off automatically to ensure enough power to control the engine
⇒ page 186, Automatic disconnection of electrical equipment. 

Windscreen washer
Fig. 121 Engine com-
partment: Windscreen
washer container
The container for the windscreen washer contains the cleaning fluid for the
windscreen or rear window and the headlight washer system. The container
is located in the engine compartment.
The container capacity is approx. 3.5 litres and, in vehicles with windscreen
washer system, approx. 5.4 litres 1)
.
Plain water on its own is not enough to clean the glass and the headlights
properly. We therefore recommend using clean water with a glass cleaning
product to eliminate any stubborn dirt (with an anti-freeze additive in win-
ter).
Although your vehicle has heated windscreen washer jets, anti-freeze
should always be added to the water in winter.
Ethanol can be used where glass cleaner with anti-freeze is unavailable. The
concentration of ethanol must be no greater than 15 %. However, remember
that anti-freeze in this proportion only protects down to -5 °C (23 °F).
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. 

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. 

206Self-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
● When it is discharged, a battery can freeze at temperatures around
0 °C (32 °F). A frozen battery must first be thawed out before connecting
the jump leads. Risk of explosion!
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 173.
● 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. 
