Lights and visibility
Dynamic cornering lights* (AFS)
The dynamic cornering lights only operate if the vehicle is travelling at more
than 10 km/h (6 mph) and the dipped headlights are on. When taking a
bend, the road is illuminated better with directional gas discharge bulbs
than with conventional fixed headlights.
A fault in the system is indicated via the flashing of the control lamp on
the instrument panel. At the same time, a text message with information or
instructions to perform necessary operations may appear on the instrument
panel display. Take the vehicle to a specialised workshop and have the fault
repaired.
If the control lamp lights up on the instrument panel but all the bulbs are
operating correctly ⇒ page 272, there may still be a fault in the dynamic
curve lighting system (AFS). Take the vehicle to a specialised workshop and
have the fault repaired.
WARNING
If the “automatic dipped beam control” is switched on, the dipped beam
headlights will not be switched on in fog. They should be switched on
manually using the light switch. The driver is personally responsible for
the correct use of lights in all situations. “Automatic headlight control”
is merely a system to support the driver. Where necessary, switch on the
lights manually using the light switch.
Fog lights with cornering function*
When the turn signal is switched on to turn or on very tight bends, the right
or left fog light automatically comes on to function as a cornering light. The
cornering light only operates if the dipped beam lights are on.
WARNING
If the “automatic dipped beam control” is switched on, the dipped beam
headlights will not be switched on in fog. They should be switched on
manually using the light switch. The driver is personally responsible for
the correct use of lights in all situations. “Automatic headlight control”
is merely a system to support the driver. Where necessary, switch on the
lights manually using the light switch.
Hazard warning lights
The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.

Bulb change General notes
Before changing any bulb, first turn off the failed component.
Do not touch the glass part of the bulb with your bare hands. The finger-
prints left on the glass will vaporise as a result of the heat generated by the
bulb, causing a reduction in bulb life and condensation on the mirror sur-
face, thus reducing effectiveness.
A bulb must only be replaced by one of the same type. The type is indicated
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle. Main headlights

- W5W - PY21W

On this type of headlight, the bulb changes must be made by the Technical Service, given
that complex elements must be removed from the vehicle and a reset must be made on the
automatic control system incorporated.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.

Note
● Depending on weather conditions (cold or wet), the headlights, 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 that of all other road users.
● Due to the difficulty in accessing some of the bulbs, any replacement
work should be done by a Technical Service. However, the following is a de-
scription of how to change the lamps except for the fog lights* and interior
lamps.
