Replacing bulbs
The front and rear light clusters of your vehi-
cle are equipped with LED light bulbs. Do not
replace the bulbs yourself. Contact a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required.
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.
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 collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the wind-
shield wipers.
!If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid

Night View Assist Plus
General notes
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera ;picks up the
infrared light and displays a monochrome
image in the multifunction display. The image
shown in the display corresponds to a road lit
up by high-beam headlamps. This enables you to see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognized by the system are visually highlighted in color in the Night
View Assist Plus display with small frame cor-
ners.
In addition, an infrared camera is integrated
into the radiator trim :. The camera helps
detect pedestrians and animals. Observe the
notes on cleaning the infrared camera
(
Ypage 337).
iInfrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf-
fic.
Important safety notes
Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not func-
tion if:
Rif there is poor visibility, e.g. due to snow,
rain, fog or spray
Rif the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
Rif the thermal imaging camera in the radia-
tor grill is dirty, fogged up or covered
Ron bends, hilltops or downhill gradients
Rat high outside temperatures
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle.
It may be the case that other objects are
marked or highlighted as well as pedestrians
and animals.
Pedestrian and animal recognition
General notes
Pedestrian or animal recognition may be
impaired or inoperative if:
Rpedestrians or animals are partially or
entirely obscured by other objects, e.g.
parked vehicles
Rthe silhouette of the pedestrian or of the
animal in the Night View Assist Plus display
is incomplete or interrupted, e.g. by pow-
erful light reflections
Rpedestrians or animals do not contrast with
the surroundings
Rthe camera system no longer recognizes
pedestrians as persons due to special
clothing or other objects
Rpedestrians are not in an upright position,
e.g. sitting, squatting or lying
Ranimals are not recognized by the system,
e.g. because of their size or shape
Pedestrian and animal recognition is deacti-
vated at temperatures above 90 ‡ (32 †).
The spotlight function and automatic delayed
switch-off are then no longer active.

Pedestrian recognition
:Night View Assist Plus display
;Readiness symbol for active pedestrian
recognition
=Highlighting
?Pedestrian recognized
Night View Assist Plus can recognize pedes-
trians using typical characteristics, e.g. the
body contours and posture of a person stand-
ing upright.
Pedestrian recognition is then switched on
automatically if:
RNight View Assist Plus is activated.
Ryou are driving faster than approximately
6 mph (10 km/h) .
Rit is dark.
If pedestrian recognition is active, readiness
symbol ;appears. Persons who are detec-
ted are highlighted by framing =. If the
pedestrian recognition system has brought a pedestrian to your attention, look through the
windshield to evaluate the situation. The
actual distance to objects and pedestrians
cannot be gaged accurately by looking at a
screen.
Animal recognition
Animals can be recognized in the following
situations:
Rdarkness
Routside built-up areas
Rbelow an outside temperature of 90 ‡
(32 †) Night View Assist Plus can recognize larger
animals such as deer, cows or horses using
typical characteristics.
The system does not detect:
Rsmaller animals, e.g. dogs and cats
Ranimals whose silhouette is not clearly rec-
ognizable
When detected, animals are marked with
small color frame corners. In contrast to
pedestrian recognition, there is no separate
readiness symbol in the multifunction dis-
play.
Activating/deactivating Night View

pedestrians.
The spotlight function is only active if:
Rpedestrian recognition is active
Rthe road surface is not lit
Rthe driving speed is at least 40 mph
(60 km/h)
Rthe "Adaptive Highbeam Assist PLUS" func-
tion is activated (

Ryou are driving in city traffic
Rthere are pedestrians located in the area of
an oncoming vehicle or a vehicle in front Activating the spotlight function
The pedestrian detection with spotlight func-
tion is running the background. If the prereq-
uisites are met, the spotlight function uses
the headlamps to flash four short pulses at a
pedestrian detected on or near to the road
surface.
