the charging cable can cause sparks and,

therefore, may ignite flammable or explo-

The vehicle is fitted with a direct current leak-

prevents any DC leaks that may occur during

charging from flowing into the home’s electri-

cal installation through the charging cable.

Never use damaged charging connectors

or cables. Before each use, check that the

connector and charging cable are not

damaged.

Check that the driving mode is deactivated

and that the charging cable and infrastruc-

ture are in perfect condition.

ously from electrical sockets of the same

safety circuit. Use a different safety circuit

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-

lation professionals.

●

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-

ble. If the cable needs to be replaced, it is

recommended to exclusively use SEAT

charging cables.
