WARNING

If works are performed on the high-voltage

lead to faults in the operation, accidents

and injuries.

High voltage can cause serious injury or

even death. Never touch the battery

poles with bare fingers, tools, jewellery or

other metal objects.

●

If the 12-volt vehicle battery has been

disconnected, discharged or replaced,

there is a chance that the combustion en-

gine may not initially turn off automatically

after moving off. If this situation lasts for

several days, contact a qualified special-

ized workshop. SEAT recommends visiting a

SEAT partner for this.

The high-voltage battery contains haz-

ardous liquid and solid substances. Emit-

ted gases can cause severe burns and

blindness. Suitable eye protection and

protective clothing must always be worn

when working on the high voltage battery

to prevent battery fluid coming into con-

tact with the skin and eyes. If the battery

fluid comes into contact with the skin or

eyes, the affected areas should be rinsed

with clean running water for at least 15

minutes, and then a doctor should be

consulted immediately.

over 24 hours.

Conservation instructions

CAUTION

SEAT recommends the following conserva-

tion instructions:

The high-voltage battery must not be used

as a stationary power supply. This can

cause irreversible damage to the high-volt-

age battery.

●

Only charge the high-voltage battery when

a low charge level is displayed on the instru-

ment cluster, or when the electric range is low

●

Conservation of the high-

CAUTION

Do not directly charge the high-voltage

battery after only a short drive in full electric

mode.

If the vehicle is parked for a long time with

the high-voltage battery discharged, it

may no longer be possible to charge the

battery or start the vehicle. Irreversible

damage could be caused to the high volt-

age battery in the long term.

to charge additional vehicles. Always

check the maximum current or power of the

safety circuit that is used. If necessary,

seek advice from qualified electrical instal-

●

For charging with alternating current,

SEAT recommends charging the high-volt-

age battery at maximum charging power

from a fixed charging station or Wallbox.

This achieves greater efficiency when

compared to charging from an electrical

socket.

Only use the charging cables supplied

with the vehicle or the charging station ca-

recommended to exclusively use SEAT

charging cables.
