enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀

and possibly roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a downhill slope,
turn the front wheels in the direction of the
curb.▷On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock. ◀

participants early on and automatically
switches the high beams on or off depending
on the traffic situation. The assistant ensures
that the high beams are switched on, whenever
the traffic situation allows. In the low speed
range, the high beams are not switched on by
the system.
General information The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The driver can intervene at any time and switch
the high beams on and off as usual.

such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways.▷In poorly-lit towns and cities and in the

Lamp and bulb replace‐
ment
General information Lights and bulbs make an essential contribution
to vehicle safety.
The manufacturer of the vehicle recommends
that you have appropriate work performed by a
dealer’s service center or another qualified
service center or repair shop if you are unfami‐
liar with it or if it has not been described here.
A spare lamp box is available from a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Information
Lights and bulbs WARNING
Bulbs can get hot during operation. Con‐
tact with the bulbs can cause burns. There is a
risk of injuries. Only change bulbs after they
have cooled off. ◀
WARNING
Work on switched-on lighting systems
can cause short circuits. There is a risk of inju‐
ries or a risk of property damage. When work‐
ing on the lighting system, switch off the lamps
in question. If necessary, heed the bulb manu‐
facturer's instructions. ◀
CAUTION
Dirty bulbs have a reduced service life.
There is a risk of property damage. Do not hold
new bulbs with your bare hands. Use a clean
cloth or something similar, or hold the bulb by
its base. ◀
Light-emitting diodes (LEDs) Some items of equipment use light-emitting di‐
odes installed behind a cover as a light source.These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is a a risk
of injury. Do not look directly into the head‐
lights or other light sources. Do not remove the
LED covers. ◀
Headlight glass Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
