Recommended camera device
maintenance
In order that the camera and radar unit shall
function correctly, the windscreen in front of the
unit must be kept clear of dirt, ice and snow, and
be cleaned regularly with water and car shampoo.
NOTE
Dirt, ice and snow covering the camera and
radar unit will reduce its function and may
prevent measurement.
This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.

City Safety™
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 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.
