beam on and off (including the control and
instrument lighting) or the daytime running
lights depending on the level of exterior
lighting. WARNING
● Never driv e w
ith daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● On vehicles with rear lights with bulbs,
when activating the d
aytime running light
the rear lights are not switched on. A vehicle
which does not have the rear lights on may
not be visible to other drivers in the dark-

When the sy s
t
em is activated and the camera
detects other vehicles that may be dazzled,
the main beam is automatically switched off.
Otherwise, the main beam is automatically
switched on.
The main beam assist generally detects illu-
minated areas and deactivates the main
beam when passing through a town, for ex-
ample. Switching the main beam assist on and off

● It is possible that the main beam headlight
contro
l does not recognise all driving situa-
tions and is limited under certain circumstan-
ces.
● When the field of vision of the camera is
dirty, c
overed or damaged, operation of the

All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-

Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The risk of
an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic con
verter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
al
s, f
or example dry grass or spilt petrol. This
could start a fire. Note
● The b atter
y will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed her

● Activation: when going abo
ve 110 km/h
(68 mph) for more than 30 seconds, the dip-
ped beam raises slightly to increase the driv-
er's visibility distance.
● Deactivation: when reduc in
g the speed of
the car below 100 km/h (62 mph), the dip-
ped beam returns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide of
the road on which
you are driving is lit more intensely.
When a car that is manufactured in a country
that drives on the right travels to a country
that drives on the left (or vice versa), it is nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied with for
designated points of the light distribution.
This is known as “Tourist light”.
