matically depending on the brightness of
the ambient light. R
With the engine running: if you have acti-
vated the daytime running lamps function

running lamps or the parking lamps and the
low-beam headlamps are switched on or off
automatically depending on the brightness
of the ambient light. X

G WARNING
When the light switch is set to X , the low-

accident.
In such situations, turn the light switch to
X .
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
Canada only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day-
time running lamps function is required by law
in Canada. It cannot therefore be deactivated.
When the engine is running and the vehicle is

lamps/low-beam headlamps go out after

switch to the X position, the manual set-
tings take precedence over the daytime run-
ning lamps.

bility of your vehicle during the day. To do this,

switch to the ` or X position, the man-
ual settings take precedence over the day-
time running lamps.

switched on and the light switch is set to the
X position. This is a pa rticularly useful
fu nction in the event of rain and fog. X
To switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2 or start the engine. X
Turn the light switch to X .

ment cluster lights up.

Replacing bulbs
Important safety notes
Xenon bulbs
G DANGER
Xenon bulbs carry a high voltage. You can get
an electr ic shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Alwa ys have work on
the Xenon bulbs carried out at a qualif ied spe-
cialist worksho p.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs
G WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if: R
you touch it R
it is hot R
you drop it R
you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
There are bulbs other than the Xenon bulbs
that you cannot replace. Only replace the
bulbs listed ( Y
page 122). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop. Replacing bulbs 121
