DRIVER SUPPORT
Limitations of City Safety steering
assistance when taking evasive
action
City Safety may have limited functionality in cer-
tain 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 power steering works at reduced power
•
- e.g. during cooling due to overheating (see
section "Speed-dependent steering force").
NOTE
The function uses the car's combined Camera
and Radar unit, which has certain general lim-
itations – see the sections "Limitations for
Camera Unit" and "Limitations for Radar Unit"
respectively.

City Safety when evasive
manoeuvres are prevented
City Safety 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 sta-
tionary 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.
Your car
Slow/stationary vehicle
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 traffic in an
adjacent lane, the function can assist the driver
by automatically starting to brake at an earlier
stage.
WARNING
The ability of City Safety to be able to
•
predict a specific situation is supplemen-
tary driver support intended to improve
driving safety – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.
City Safety is not a substitute for the driv-
•
er's attention and judgement. The driver
is always responsible for ensuring the car
is driven in a safe manner, at the appro-
priate speed, with an appropriate distance
to other vehicles, and in accordance with
current traffic rules and regulations.
