City Safety™
Function

Laser sensor transmitter and receiver window
City Safety™ detects the traffic in front of the
car with a laser sensor fitted in the top edge
of the windscreen. If there is an imminent risk
of collision, City Safety™ will automatically
brake the car, which may be experienced as
sudden braking.
If the speed difference is 4-15 km/h in relation
to the vehicle in front then City Safety™ can
completely prevent a collision.
City Safety™ activates a short, sharp braking
and stops the car in normal circumstances,
just behind the vehicle in front. For most dri-
vers this is well outside normal driving style

and may be experienced as being uncomfort-
able.
If the difference in speed between the vehi-
cles is greater than 15 km/h then City
Safety™ may not prevent the collision on its
own. To obtain full brake force, the driver
must depress the brake pedal. This could
then make it possible to prevent a collision,
even at speed differences above 15 km/h.
When the function is activated and brakes,
the combined instrument panel shows a text
message to the effect that the function is/has
been active.

Operation
NOTE
The City Safety™ function is always ena-
bled after the engine has been started via
key position I and II (see page 81 on key
positions).

In certain situations, it may advisable to disa-
ble City Safety™, e.g. where leafy branches
could sweep over the bonnet and/or wind-
screen.
After starting the engine City Safety™ can be
deactivated as follows:
•
Using MY CAR in the centre console's
screen with its menu system, search and
Settings Car settings
locate
support systems City Safety. Select
Off
the option. For more information on
the menu system MY CAR, see
page 213.
However, the function will be enabled the
next time the engine is started, regardless
of whether the system was enabled or
disabled when the engine was switched
off.
WARNING
The laser sensor also transmits laser light
when City Safety™ is disabled manually.
To enable City Safety™ again:
•
Follow the same procedure as for disa-
bling, but select the On option.
