DRIVER SUPPORT
||
WARNING
•
The City Safety is supplementary driver
support intended to improve driving safety
– it cannot handle all situations in all traf-
fic, weather and road conditions.
•
The City Safety auto-brake function can
prevent a collision or reduce collision
speed, but to ensure full brake perform-
ance the driver should always depress the
brake pedal – even when the car auto-
brakes.
•
The warning and steering assistance are
only activated if there is a high risk of col-
lision – you must therefore never wait for
a collision warning or for City Safety to
intervene.
•
The warning and brake intervention for
pedestrians and cyclists are deactivated
at vehicle speeds exceeding 80 km/h
(50 mph).
•
City Safety does not activates any auto-
brake functions in the event of heavy
acceleration.
•
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.

•
The driver is advised to read all sections
in the Owner's Manual that relate to City
Safety to learn about factors such as its
limitations and what the driver should be
aware of before using the system (see
the list of links for all subsections).

Parameters and subfunctions for
City Safety
City Safety can avoid a collision with a vehicle, a
cyclist, a pedestrian or a larger animal in front by
reducing the car's speed with the auto-brake
function.
If the speed difference is greater than the follow-
ing specified speeds, the City Safety auto-brake
function cannot prevent a collision but mitigates
the consequences of it.
Vehicles
For a vehicle in front, City Safety can reduce the
speed by up to 60 km/h (37 mph).
cyclists
For a cyclist, City Safety can reduce the speed by
up to 50 km/h (30 mph).
Pedestrians
For a pedestrian, City Safety can reduce speed by
up to 45 km/h (28 mph).
Large animals
In the event of a risk of a collision with a large
animal, City Safety can reduce the car's speed by
up to 15 km/h (9 mph).
The brake function for large animals is primarily
intended to reduce the force of the impact at
higher speeds and is most effective at speeds
above 70 km/h (43 mph) but less effective at
lower speed.
