Lights Introduction
Observe the legal requirements regarding the use of vehicle lights in each
country.
The driver is personally responsible for the correct use and adjustment of
the lights in all situations.
Additional information and warnings:
● Exterior detail ⇒ page 6
● SEAT information system ⇒ page 22
● Changing bulbs ⇒ page 264
WARNING
If the headlights are set too high and the main beam is not used correct-
ly, there is a risk of dazzling or distracting other road users. This could
result in serious accident.
● Always make sure that the headlamps are correctly adjusted.
● Never use the main beam or flashed headlamps as this could dazzle
other drivers.

Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while a test of the function is being carried out. They will
switch off after a few seconds.
WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
● Park the vehicle at a suitable distance away from the traffic ensuring
that the exhaust system is not in contact with inflammable material, for
example, dry grass, fuel, oil, etc.
● A faulty vehicle represents a risk of accident for the driver and for oth-
er road users. If necessary, switch on the hazard warning lamps and put
out the warning triangle to advise other drivers. 

Note
● The filling nozzles of natural gas pumps can differ in the way they are
operated. If you are unacquainted with the pump, it is advisable that a
member of staff of the service station performs the refuelling operation.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of a fault in the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. 

Practical information
Information for replacing bulbs
Checklist
To replace a bulb, carry out the following operations always in the order giv-
en ⇒ 
:
1. Park the vehicle a safe distance from traffic and on suitable ground.
2. Apply the handbrake firmly ⇒ page 134.
3. Turn the light switch to position 0 ⇒ page 84.
4. Move the gear lever into the neutral position ⇒ page 84.
5. Stop the engine and remove the key from the ignition ⇒ page 119.
6. Automatic gearbox: move the selector lever to position P
⇒ page 124.
7. Manual gearbox: Select a gear ⇒ page 124.
8. Allow the corresponding bulb to cool.
9. Visually inspect fuses to see if any are blown ⇒ page 261.
10. Replace the bulb according to the instructions ⇒ 
. Bulbs should
only be replaced by new identical models. Bulb information is dis-
played on the bulb socket or on the bulb itself.
11. In general, never touch the bulb glass directly. The heat of the bulb would cause the fingerprint to evaporate and condense on the reflec-
tor. This will impair the brightness of the headlight.
12. Check if the new bulb is working. If the bulb is not working, it maynot have been correctly fitted, it could be damaged or the connector
may not be correctly connected.
13. Every time a bulb for the headlights is replaced, visit a specialised workshop to check the headlights.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
CAUTION
Always remove and fit headlights carefully to avoid damage to the paint-
work and other vehicle parts. 
