DRIVER SUPPORT
City Safety™
64
City Safety can alert the driver using a visual,
acoustic and brake pulse warning to help
him/her detect pedestrians, cyclists, larger ani-
mals and vehicles that suddenly appear - the car
then attempts to brake automatically unless the
driver acts within a reasonable time him/herself.
Location of the radar unit.
City Safety can prevent a collision or reduce colli-
sion speed.
City Safety is an aid to assist a driver who is at
risk of colliding with a pedestrian, large animal,
cyclist or a vehicle.
The City Safety function can help the driver to
avoid a collision when driving in queues, e.g.
when changes in the traffic ahead, combined with
a lapse in attention, could lead to an incident.
The function is not available in all markets.

The function helps the driver by automatically
braking the car in the event of an imminent risk
of collision if the driver does not react in time by
braking and/or swerving.
City Safety activates a short, sharp braking proce-
dure, normally stopping the car just behind the
vehicle in front.
City Safety is activated in situations where the
driver should have started braking earlier, which
is why it cannot help the driver in every situation.
City Safety is designed to be activated as late as
possible in order to avoid unnecessary interven-
tion.
The driver or passengers are not normally aware
of City Safety - it only intervenes in a situation
where a collision is immediately imminent.
WARNING
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.
