Daytime running lights: In vehicles for countries where daytime running
lights are obligatory and in all vehicles with AFS headlights, daytime run-
ning lights are turned on or off with the ignition. Daytime running lights
have main beam flashers, as usual, but not the dipped beam headlight
function
The dipped beam headlights will only work with the ignition on. The head-
lights are automatically switched to side lights after the ignition has been
switched off.
If the side lights or the dipped beam headlights are turned on, the  sym-
bol will come on together with the lights switch.
Note
● If the lights are left on after the key has been taken out of the ignition
lock, a buzzer sounds when the driver door is opened.
● Observe all relevant legal requirements when using the signalling and
lighting systems described here.
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful 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 misted. 

Automatic headlight switch* (sensor-controlled)
If you set the light switch to “AUTO”, the dipped headlights
will switch on and off automatically according to the ambi-
ent light level.
Fig. 83 Detailed view of
the dash panel: Light
switch
Turning on dipped beam headlights
– Turn the light switch ⇒ Fig. 83 to the AUTO position.
Turning off dipped beam headlights
– Turn the light switch to position O.
The symbol on the switch lights up when the switch is in the AUTO position.
The dipped beams, side lights, tail lights and number plate lights come on
together when the headlights are switched on automatically.
When you are using the automatic headlights switch, you can also operate
the main beam headlights, however, please note the following: If you ena-
ble the main beam headlights while using the automatic headlights func-
tion during the day (e.g. when driving through a tunnel), but do not disable them again, only the dipped beam headlights will come on the next time
the lights are automatically switched on. To be able to use the main beam
headlights again, you must first pull the main beam lever back to the "off"
position and then push it forward again to "on".
The side lights, headlights, fog lights and rear fog light can still be switched
on manually in the normal way by using lights switch
⇒ page 115.
The interior mirror is fitted with sensors that measure the ambient light. The
dipped beam headlights will be switched on automatically if the available
light drops below the factory preset value (for instance when driving
through a tunnel, etc.). The headlights switch off again automatically when
the light level increases ⇒ 
.
WARNING
● The automatic dipped beam headlights are only intended to assist
the driver. Automatic dipped beam headlights do not relieve the driver of
his or her responsibility to control them and turn off or turn on the lights
manually according to weather or lighting conditions. The light sensors
are, for example, unable to detect rain and fog - you should therefore al-
ways switch on the dipped beam headlights  manually in these condi-
tions and when driving after dark.
● Observe all relevant legal requirements when using the signalling
and lighting systems described here.
Note
● If automatic headlight switching is activated, when the ignition is turned
off the dipped beam headlights are turned off, and when the key is removed
from the ignition the side lights are turned off.
● If you have to attach any type of sticker on the windscreen, do not do so
in front of the sensors. Doing so could prevent the automatic dipped beam
headlight or anti-dazzle function from working correctly or even from work-
ing at all. 

Activating the function
–Briefly press the knob ⇒ Fig. 84 to release it from its set posi-
tion.
– Turn the knob to position 1.
– Press the knob in again to prevent the setting from being
changed unintentionally.
Deactivating the function
– Briefly press the knob ⇒ Fig. 84 to release it from its set posi-
tion.
– Turn the knob to position 0.
– Press the knob in again to prevent the setting from being
changed unintentionally.
The coming home and leaving home functions are controlled by light sen-
sors in the interior mirror housing. The system will function when the follow-
ing requirements are met:
● The knob is set to position 1.
● The headlights and the ignition are switched off.
● Dark conditions; the sensors register little or no light.
Coming home
When the system is enabled and it is dark, the corresponding exterior lights
switch on as soon as the driver door is opened.
The exterior lights will stay on for up to a maximum of 2 minutes as long as
one of the doors or the rear lid is open.
The exterior lights stay on for about 30 seconds to light up the area around
the vehicle after all the doors and the rear lid have been closed. This time interval is factory-set, but you can have it changed by a special-
ised workshop to suit your own requirements (max. setting is 60 seconds).
Leaving home
The exterior lights are switched on when the vehicle is unlocked with the

button on the remote control key.
The exterior lights go out when the driver door is opened or after 60 sec-
onds when the vehicle locks itself again automatically
⇒ page 106.
WARNING
Before leaving the vehicle, remove the key from the ignition, as the lights
will not go out if the coming home function is activated. This will lead to
battery discharge and vehicle breakdown.
Note
● If you always wish to use the coming home and leaving home functions,
you can leave them permanently switched on. As the system is controlled
via a photosensor, it will only work in dark conditions.
● Permanent use of the coming home and leaving home functions, partic-
ularly on short journeys, will increase the load on the battery. To make sure
the battery is always sufficiently charged, occasionally drive longer distan-
ces.
● If the fog lights have been switched on by the coming home and leaving
home functions, they will always be switched off when you switch on the ig-
nition.
● Observe all relevant legal requirements when using the signalling and
lighting systems described here. 

Bulbs
General information
You can change the following bulbs for exterior lights yourself:
● Main headlights: all bulbs (except xenon headlights)
● Tail lights: all bulbs
● Side turn signal bulb
The following bulbs can only be changed by a specialised workshop:
● Main headlights: Xenon* bulb ⇒ page 271
● Front fog lights: Bulb
As a rule, you require a certain degree of practical skill to change defective
bulbs. This applies in particular to those bulbs which are only accessible
from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed by a spe-
cialised workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment yourself, be
aware of the safety risks involved ⇒ page 227 ⇒ 
in Types of bulbs on
page 265. The name of many of the lamps fitted by SEAT ends in "LL". This means Long
Life. These lamps are used for functions with a long service time (dipped
beam, side lights, daylight driving, etc.). This does not apply to lamps with
a shorter service time (turn signals, etc.). A lamp with the same name ex-
cept for the last two letters, "LL“ or “SLL”, is compatible, but will have a
service life of approximately half of the LongLife lamps.
When replacing lamp bulbs, the same type of bulb as originally fitted
should always be used where possible.

Changing bulbs. Halogen headlights Types of bulbs
You must only replace a bulb with a bulb of the same type. The name can be
found on the base of the bulb holder.

WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm - risk of burns!
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. If not, a
short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful 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 misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also in that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, be deposited on the
reflector and impair its surface. 
