Limitations of City Safety steering
assistance when taking evasive
action
City Safety may have limited functionality in
certain situations and fail to intervene e.g.:
outside the speed range 50-100 km/h
•
(30-62 mph)
if the driver initiates an evasive manoeuvre
•
if the steering servo creating speed-
•
dependent steering wheel resistance is
working at reduced power – e.g. when
cooling due to overheating.
NOTE
This function uses the car's camera and
radar units, which have certain general lim-
itations.

Automatic braking in the event of
an impeded evasive manoeuvre
with City Safety
City Safety 16 has the facility to assist the
driver by automatically braking the car earlier
when it is not possible to avoid a collision by
only steering away.
City Safety assists the driver by continuously
attempting to anticipate whether there are
"escape routes" to the side in case a slow or
stationary vehicle ahead is discovered at a late
stage.
Your car (1) "sees" no options for evading the vehicle
ahead (2) and can therefore auto-brake earlier.

DRIVER SUPPORT
City Safety does not intervene with the auto-
brake function as long as the driver him/
herself has the opportunity to avoid a collision
via a steering manoeuvre.
However, if City Safety anticipates that an
evasive manoeuvre is not possible due to traf-
fic in an adjacent lane, the function can assist
the driver by automatically starting to brake at
an earlier stage.
