with limitations may not be detected at all.
Always monitor the traffic and the vehicle's
surroundings directly and do not become dis-
tracted.

@) Note
— Obstacles may disappear from the measure-
ment range when approaching them, even if
they were already detected.
—Insome situations, the ability of the sen-
sors and cameras to detect and display cer-
tain objects may be limited.
— Objects located above the coverage area,
such as bumpers on parked cars, garage
doors that are partially open, or objects
that are hanging
— Low obstacles
— Narrow objects, such as barrier chains, fo-
liage, poles, or fences
— Projecting objects, such as trailer draw
bars
— Objects with certain surfaces and struc-
tures, such as fabric
@ Tips
— The sensors and cameras and the areas
around them must not be obstructed be-
cause this can impair the function of the
systems that depend on them. Make sure
that the sensors and cameras are free of
snow, ice, and other deposits. Do not use
any accessories, stickers, or other objects
that extend into the range of the sensors
and cameras.
— On vehicles that have factory-installed li-
cense plate brackets on the front of the ve-
hicle, the brackets may only be replaced
with ones that are the same size and made
of the same material. Do not install any li-
cense plate brackets on the front of vehicles
that do not have factory-installed brackets.
Otherwise, the function of the system could
be impaired.
— The function of the sensors and cameras
may be limited when light and visibility con-
ditions are poor, for example when driving
into a tunnel, when there is glare, or when
there are reflective objects.
— External ultrasonic sensors, such as those in
other vehicles, can interfere with the sen-
sors.
— The coverage areas of the sensors > fig. 90
and cameras > fig. 91 are diagrams and do
not represent a true-to-scale image of the
sensor ranges.

Night vision assist
Applies to: vehicles with night vision assist
Night vision assist helps you when it is dark by
using an infrared camera to monitor the area in
front of your vehicle, within the limits of the sys-
tem. It can display objects up to a distance of ap-
proximately 1000 feet (300 m).
Pedestrian and wild animals are detected by
measuring the temperature difference between
the object and the background. Pedestrians and
wild animals will not be detected if the tempera-
ture difference is too small. The pedestrian and
wild animal marking feature is deactivated at
temperatures above approximately 77 °F (25 °C)
and when it is light outside.
The thermal image detected by the camera is dis-
played in the instrument cluster. Warm areas
generally appear lighter and cold areas appear
darker.
The camera for the night vision assist is located
in the vehicle's radiator grille > page 131. Make
sure the night vision camera is not covered by
stickers, deposits, or any other obstructions be-
cause this can impair the night vision assist func-
tion. Follow the information about cleaning
=> page 261.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 129.
— Night vision assist can only detect pedes-
trians and wild animals located within the
range of the infrared camera.
— Night vision assist cannot detect pedes-
trians or wild animals and mark them if:
