When your own car is reversing, City Safety is
temporarily deactivated.
City Safety™ - limitations
WARNING
The sensor in City Safety is designed to
detect cars and other large vehicles in front of
the car irrespective of whether it is day or
night.
The laser sensor also transmits laser light
when City Safety™ is disabled manually.
City Safety is not activated at low speeds -
below 4 km/h (3 mph), which is why the sys-
tem does not intervene in situations where a
vehicle in front is being approached very
slowly, e.g. when parking.

However, the function does have some limita-
tions.

City Safety™ - limitations (p. 226)
Driver commands are always prioritised,
which is why City Safety does not intervene in
situations where the driver is steering or
accelerating in a clear manner, even if a colli-
sion is unavoidable.
The sensor's limitations mean that City Safety
has poorer functionality - or none at all - in
e.g. heavy snowfall or rain, dense fog, dust
storms or white-out situations. Misting, dirt,
ice or snow on the windscreen may also dis-
rupt the function.

MY CAR (p. 119)
When City Safety has prevented a collision
with a stationary object the car remains sta-
tionary for a maximum of 1.5 seconds. If the
car is braked for a vehicle in front that is mov-
ing, then speed is reduced to the same speed
as that maintained by the vehicle in front.

Low-hanging objects, e.g. a flag/pennant for
projecting load, or accessories such as auxili-
ary lamps and bull bars that are higher than
the bonnet limit the function.
The laser beam from the sensor in City Safety
measures how the light is reflected. The sen-
sor cannot detect objects with low reflection
capacity. The rear sections of the vehicle
generally reflect the light sufficiently thanks to
the number plate and rear light reflectors.
On a car with manual gearbox the engine
stops when City Safety has stopped the car,
unless the driver manages to depress the
clutch pedal beforehand.
On slippery road surfaces the braking dis-
tance is extended, which may reduce the
capacity of City Safety to avoid a collision. In
such situations the ABS14 and ESC15 systems
will provide best possible braking force with
maintained stability.
