●

Work on the high-voltage system, as well

as on any systems that may be indirectly in-

fluenced by it, should only be carried out by

specialized personnel with the correspond-

ing qualifications and training.

●

WARNING

Always inform the fire fighters and the

emergency service that the vehicle is fitted

with a high-voltage battery.

The vehicle’s high-voltage network and the

high-voltage battery are hazardous and can

cause burns and other injuries, including

fatal electric shocks. All high voltage cables

are identified by the colour orange.

●

Work in the immediate vicinity of high-

voltage cables and high-voltage compo-

nents with tools that are sharp, give off

shavings or that have heat sources, such as

hot air, thermal bonding or welding work,

may only be performed after disconnecting

the voltage. The high voltage should only

be disconnected by specialized personnel

with the corresponding qualifications and

training.

WARNING

If works are performed on the high-voltage

system and on the high-voltage compo-

nents in an inappropriate manner, this may

lead to faults in the operation, accidents

and injuries.

●

It should always be assumed that the

high-voltage battery is fully charged and

that all of its components are live. This may

also be the case when the ignition is switch-

ed off.

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 specialized

workshop. CUPRA recommends visiting a

CUPRA 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 bat-

tery to prevent battery fluid coming into

contact with the skin and eyes. If the bat-

tery 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.

by specialized personnel with the corre-

maintenance instructions are essential for

maintaining the vehicle's value over time.

If you plan to leave your vehicle stationary

for prolonged periods of time, park with a

charge level of at least 30%. This situation

occurs, for example, when you leave your

vehicle at the airport before a trip.

Please also observe the applicable CUPRA

warranty conditions for the high-voltage bat-

tery.

●

Do not expose the vehicle to outside tem-

peratures below -30°C or above 60°C for

over 24 hours.

●

In principle, lithium ion batteries are subject

to ageing and wear and tear throughout their

useful life due to their physical and chemical

characteristics. Correct use of the high-volt-

age battery makes a considerable contribu-

tion to keeping it in a reliable state in the long

term and to achieving high useful capacity

and range. Therefore, it is extremely impor-

tant to respect the following conservation in-

structions for the high voltage battery. These
