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

! 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

Driving and parking Z

! 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.
PARKTRONIC is activated automaticall yw hen

Parking Guidance
Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. As uitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You may also use PARKTRONIC
( Y
page 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. When maneuvering, parking or
pulling out of ap arking space, make sure that
there are no persons, animals or object sint he
area in which you are maneuvering.
G WARNING
If object sa re located above the detection
range, Parking Guidance may provide steering
instructions too soon. You may cause ac olli-
sion as ar esult. There is ar isk of an accident.
If object sa re located above the detection
range, stop and switch off Parking Assist. ! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at as harp
angle. Otherwise, you may damage the
wheels or tires.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Use Parking Guidance for parking spaces: R
that are paralle ltot he direction of travelR
that are on straight roads, not bends R
that are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly. R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.152
