Emergencies
If you choose to change the engine compart-
ment l
amp
s yourself, remember that it is a
dangerous area ››› in Working in the en-
gine c omp
ar

tment on page 270.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder.
Depending on how equipped the vehicle is,
there are different sets of headlights and tail
lights:
● Halogen headlights.
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar bulb light
● LED rear light*
Ful
l-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remo v

e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before c
hanging a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u

sed bulbs in the proper manner. Note
● Ple a

se check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users. ●
Bef or

e changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface.
● Depending on the level of equipment fitted
in the vehic
le, LEDs may be used for part or
all of the interior and/or exterior lighting.
LEDs have an estimated life that exceeds than
that of the car. If an LED light fails, go to an
authorised workshop for its replacement. 104

Operation
Note
● Never l e
ave any valuable items in the vehi-
cle unattended. Even a locked vehicle is not a
safe.
● If the diode on the driver door sill lights up
for about 30 sec
onds when the vehicle is
locked, the central locking system or anti-
theft alarm* is not working properly. You
should have the fault repaired at a SEAT Offi-
cial Service or specialised workshop.
● The vehicle interior monitoring of the anti-
theft a
larm* system will only function as in-
tended if the windows and the sunroof* are
closed. Car key

Spare key
To obtain a spare key and other vehicle keys,
the vehicle chassis number is required.
Each new key contains a microchip which
must be coded with the data from the vehicle
electronic immobiliser. A vehicle key will not
work if it does not contain a microchip or the
microchip has not been encoded. This is also
true for keys which are specially cut for the
vehicle.

impurities drops to within a normal range, re-
circulation mode is switched off.
The system is unable to detect unpleasant
smells. The air recirculation will
not connect aut o-
matically in versions without humidity sensor
and in the following external conditions:
● The outside temperature is lower than +3°C
(+38°F).
● The cooling system is switched off and the
outside temper
ature is below +10°C (+50°F).

The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available. Trailer maximum electricity consumption

Note
● If the r e

ar lights of the trailer are not cor-
rectly connected, the vehicle electronics may
be damaged.
● If the trailer absorbs excessive electric cur-
rent, the v
ehicle electronics may be dam-
aged.
● Never connect the trailer's electric system
directly t

CAUTION
● Do not mi x
cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
vis
ibility through the windscreen, and leads
to loss of visibility in headlights in models
