Important safety notes
G WARNING
Adaptive Highbeam Assist does not recognize
road users: R
who have no lights, e.g. pedestrians R
who have poor lighting, e.g. cyclists R
whos el ighting is blocked ,e .g. by ab arrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamp sw il ln ot be deac-
tivated or wil lbea ctivated regardless. There is
ar isk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamp si n
good time.
Adaptive Highbeam Assist cannot take into
account road ,w eather or traffic conditions.
Adaptive Highbeam Assist is only an aid .Y ou are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
restricted if there is: R

Windshield wipers
Switching the windshield wipers
on/off
! Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratc ht he glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, alway su se
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratc ht he windshield.
For this reason, you should alway ss witch off
the windshield wipers in dry weather. Combination switch

PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensor sint he front
bumper and four sensor sint he rear bumper.
PARKTRONIC indicates visually and audibly the
distanc eb etween your vehicle and an object.
PARKTRONIC is only an aid. It is not ar eplace-
ment for your attention to your immediate sur-
roundings .Y ou are alway sr esponsible for safe
maneuvering, parking and exitin gap arking
space. When maneuvering, parking or pulling
out of ap arking space, make sure that there are
no persons ,a nimals or object sint he area in
which you are maneuvering.Driving systems 149

! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on at ruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
