Changing bulbs requires a certain degree of

practical skill. If you are unsure, SEAT recom-

mends that you consult a technical service or

request assistance from a specialist. In general

a specialist is needed if, in addition to the bulbs,

other vehicle components require removal.

Full-LED headlights handle all light functions

(daylight, side light, turn signal, dipped beam

and route light) with light emitting diodes (LEDs)

as a light source. They have been designed to

last the lifetime of the vehicle and the bulbs

cannot be replaced. In case of headlight fail-

ure, go to an authorised workshop to have it

replaced.

●

Depending on weather conditions (cold or

wet), the front lights, the fog lights, the tail

lights and the turn signals may be tempora-

rily misted. This has no inﬂuence on the use-

ful life of the lighting system. By switching on

the lights, the area through which the beam

of light is projected will quickly be demisted.

However, the edges may continue to be mis-

ted.
