Large animals Optimal examples of what City Safety would interpret as
a large animal: stationary or moving slowly and with clear
body contours.
For optimal performance, the system's function
for detecting large animals (e.g. moose, horses,
etc.) needs the clearest possible information
about body contours. This entails being able to
detect the animal straight from the side in combi-
nation with normal movements for that animal.
If parts of the animal's body are not visible to the
function's camera, the system will not be able to
detect the animal.
City Safety can detect large animals even in dark
conditions if they are illuminated by the vehicle's
headlights.WARNING City Safety is supplementary driver support,
but it cannot detect all large animals in all sit-
uations and, for example, cannot see:
• partially obscured larger animals.
• larger animals seen from the front or from
behind.
• running or fast moving larger animals.
• larger animals if the contrast of the ani-
mal's background is poor - warning and
brake interventions may then occur late
or not at all.
• smaller animals such as cats and dogs.
The driver is always responsible for ensuring
that the vehicle is driven correctly and with a
safety distance suitable for the speed.

can assist the driver when turning in
the path of an oncoming vehicle in an intersec-
tion. : Sector in which City Safety can detect an oncoming
vehicle in crossing traffic.
In order for City Safety to detect an oncoming
vehicle in situations where there is a risk of a col-
lision, that vehicle must be within the sector in
which City Safety can analyze the situation.
The following criteria must also be met:
• your vehicle's speed must be at least 4 km/h
(3 mph)
• your vehicle must be making a left turn
• the oncoming vehicle's headlights must be
on

WARNING
•
The "City Safety in crossing traffic" func-
tion is supplementary driver support
intended to improve driving safety – it
cannot handle all situations in all traffic,
weather and road conditions.
• Warnings and brake interventions due to
a collision risk with an oncoming vehicle
often come very late.
• Never wait for a collision warning or for
City Safety to intervene.
• City Safety is not a substitute for the driv-
er's attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

City Safety™ (p. 335) Limitations of City Safety in
crossing traffic
In certain situations, it may be difficult for City
Safety to help the driver avoid a collision with
crossing traffic. For example:
• on slippery roads when Electronic Stability
Control (ESC) is actively operating
• if an approaching vehicle is detected at a late
stage
• if the oncoming vehicle is partially obstructed
by another vehicle or object
• if the oncoming vehicle's headlights are off
• if the oncoming vehicle is moving erratically
and e.g. suddenly changes lanes at a late
stage.
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

City Safety and delayed evasive
maneuvers
City Safety can assist the driver by automatically
braking the vehicle when it is not possible to
avoid a collision by steering alone.
City Safety assists the driver by periodically
attempting to predict possible "escape routes" to
the sides of the vehicle in the event a slow-mov-
ing or stationary vehicle were to be detected at a
late stage.
Your vehicle (1) cannot detect any potential escape
routes for veering away from the vehicle ahead (2) and
may therefore apply the brakes at an earlier stage.
Own vehicle
Slow-moving/stationary vehicles
City Safety will not intervene to automatically
apply the brakes if it is possible for the driver to
avoid a collision by steering the vehicle. However, if City Safety determines that an eva-
sive maneuver would not be possible due to traf-
fic in the adjacent lane(s), the function can assist
the driver by automatically starting to apply the
brakes at an earlier stage.
WARNING
•
The possibility of City Safety predicting a
certain situation is supplementary driver
support intended to improve driving safety
– it cannot handle all situations in all traf-
fic, weather and road conditions.
• City Safety is not a substitute for the driv-
er's attention and judgment. The driver is

cle is driven in a safe manner, at the
appropriate speed, with an appropriate

WARNING•
Warnings and brake interventions can be
triggered late or not at all if the traffic sit-
uation or external influences prevent the
camera and radar unit from properly
detecting pedestrians, cyclists, large ani-
mals or vehicles ahead of the vehicle.
• To be able to detect vehicles at night, its
front and rear lights must work and illumi-
nate clearly.
• The camera and radar unit have a limited
range for pedestrians and cyclists – the
system can provide effective warnings
and brake interventions if the relative
speed is lower than 50 km/h (30 mph).
For stationary or slow-moving vehicles,
warnings and brake interventions are
effective at vehicle speeds of up to
70 km/h (43 mph). Speed reduction for
large animals is less than 15 km/h
(9 mph) and can be achieved at vehicle
speeds over 70 km/h (43 mph). At lower
speeds, the warning and brake interven-
tion for large animals is less effective.
• Warnings for stationary or slow-moving
vehicles and large animals can be disen-
gaged due to darkness or poor visibility. •
Warnings and brake interventions for
pedestrians and cyclists are disengaged
at vehicle speeds over 80 km/h
(50 mph).
• Do not place, affix or mount anything on
the inside or outside of the windshield, or
in front of or around the camera and
radar unit – this could disrupt camera-
based functions.
• Objects, snow, ice or dirt in the area of
the camera sensor can reduce the func-
tion, disengage it completely or give an
improper function response.
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit,
which has some general limitations – see the

Cross Traffic Alert*
CTA 86
is a supplementary driver support system
to BLIS 87
that is intended to help the driver
detect vehicles crossing behind the vehicle
while backing up. CTA overview.
CTA supplements BLIS by detecting traffic cross-
ing from the side, e.g. when backing out of a
parking space.
CTA is primarily designed to detect vehicles, but
in certain cases can also detect pedestrians or
smaller objects such as bicycles.
CTA is only active when the vehicle is moving
backward or if reverse gear is engaged. If CTA detects that something is approaching
your vehicle from the side:
• an audible signal will sound from either the
left or right speaker, depending on which
side of your vehicle the object is approaching
from.
• an icon will illuminate in the PAS 88
graphic
on the screen.
• an icon will appear in the Park Assist Cam-
era's Top view. Illuminated CTA icon in the PAS

• The responsibility for reversing the vehicle
safely and using good judgment always
rests with the driver.

WARNING
•
The Driver Alert Control function is sup-
plementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.
• Driver Alert Control must not be used to
extend a period of driving. The driver
should plan in breaks at regular intervals
and make sure they are well rested.
• Driver Alert Control is not a substitute for
the driver's attention and judgment. The
driver is always responsible for ensuring
the vehicle is driven in a safe manner, at
the appropriate speed, with an appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.
WARNING An alarm from Driver Alert Control should be
taken very seriously since a sleepy driver is
often not aware of their own condition.
If the alarm sounds or you feel fatigued:
• Stop the vehicle safely as soon as possi-
ble and rest.
Studies have shown that it is just as danger-
ous to drive while tired as it is to drive under
the influence of alcohol or other stimulants.
