DRIVER SUPPORT
306
City Safety
™
City Safety
™
is a support system designed to
help alert the driver to pedestrians, cyclists, large
animals and vehicles that may appear suddenly
in front of your vehicle by providing visual, audi-
ble and haptic alerts. The vehicle will brake auto-
matically if the driver is unable to react quickly
enough.
City Safety introduction
Location of the camera and radar sensor (generic illus-
tration)
City Safety can help prevent a collision or lower
the vehicle's speed at the point of impact.
WARNING
•
City Safety
™
is a supplemental aid to the
driver. It can never replace the driver’s
attention to traffic conditions or his/her
responsibility for operating the vehicle in
a safe manner.
•
City Safety
™
does not function in all driv-
ing situations or in all traffic, weather or
road conditions.
The City Safety function can help the driver avoid
a collision when e.g., there is a sudden change in
the traffic ahead if the driver's does not take
action.
The function assists the driver by applying the
brakes automatically if there is an imminent risk
of a collision and the driver does not react in
time.
City Safety triggers brief, forceful braking in an
attempt to stop your vehicle immediately behind
the vehicle or object ahead. This braking may be
perceived as being very sudden.
City Safety activates in situations where the driver
has not applied the brakes in time, which means
that the system cannot help the driver in all situa-
tions.
City Safety is designed to intervene as late as
possible to help avoid unnecessary activation.
Normally, the occupants of the vehicle will not be
aware of City Safety except when the system
intervenes when a collision is imminent.
City Safety parameters
City Safety can help avoid a collision with a
vehi-
cle or cyclist ahead
by reducing your vehicle's
speed by up to 30 mph (50 km/h).
In the case of
pedestrians
, City Safety can
reduce speed by up to 28 mph (45 km/h).
If the
difference in speed
is greater than
30 mph (50 km/h) or 28 mph (45 km/h) respec-
tively, City Safety's auto-brake function cannot
prevent a collision but it can help mitigate the
effects of the collision.
If there is a risk of colliding with a
large animal
,
City Safety can reduce the vehicle's speed by up
to 9 mph (15 km/h). The braking function for
large animals is primarily intended to mitigate the
force of a collision at higher speeds. Braking is
most effective at speeds above 43 mph
(70 km/h) and less effective at lower speeds.
