Practical tips
warmed the windscreen with the ventila-
tion system. The antifreeze could freeze on
the windscreen and reduce visibility.
CAUTION
Never mix an unsuitable antifreeze or other
similar additives with the windscreen wash-
er water. A greasy layer may be formed on
the windscreen which will impair visibility.
Use clean water with a window cleaner
recommended by CUPRA.
If necessary, add a suitable antifreeze to
the water in the reservoir.
CAUTION
Do not mix cleaning products recom-
mended by CUPRA with other products.
This could lead to flocculation and may
block the windscreen washer jets.
When topping up service fluids, make ab-
solutely certain that you fill the fluids into
the correct reservoirs. Using the wrong flu-
ids could cause serious malfunctions and
engine damage!
Lack of window washer fluid causes the
view through the windscreen to be ob-
scured.
12-volt battery
General information
The battery is located in the engine com-
partment
page 318 or luggage compart-
ment (PHEV hybrid vehicles)
page 328
and is practically maintenance free. It is
checked as part of the Inspection Service.
Nevertheless, check the terminals are clean
and have the correct tightening torque, es-
pecially in summer and winter.
All work on batteries requires specialist
knowledge. Please refer to a specialised CU-
PRA Service, SEAT Official Service or a work-
shop specialising in batteries: risk of burns or
exploding battery!
The battery must not be opened. Never try
to change the fluid level of the battery. Oth-
erwise explosive gas is released from the
battery that could cause an explosion.
Battery warning indications
Wear eye protection.
Battery acid is extremely corrosive. Wear pro-
tective gloves and eye protection. Rinse any
splashes of electrolyte with plenty of water.
Fires, sparks, open flames and smoking are pro-
hibited.
The battery should only be charged in a well-
ventilated zone. Risk of explosion!
Keep children away from acid and batteries!
Always follow the instruction manual.
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. These functions will require reset-
ting after the battery is reconnected.
When disconnecting the battery from the
vehicle on-board network, disconnect first
the negative cable and then the positive ca-
ble.
Deactivate the anti-theft alarm before you
disconnect the battery. Otherwise the alarm
will be triggered.
If the vehicle is not used for long periods
The vehicle has a system for monitoring the
current consumption when the engine is left
unused for long periods of time
page 330 .
Some functions, such as the interior lights,
or the remote door opening, may be tempo-
rarily disabled to prevent the battery from
running flat. These functions will come back
on as soon as the ignition is switched on and
the engine started.
