City Safety™ - limitations
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.
However, the function does have some limita-
tions.
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
disrupt the function.
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 sensor 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 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 ABS
13
and ESC
14
sys-
tems will provide best possible braking force
with maintained stability.
When your own car is reversing, City Safety™
is temporarily deactivated.
City Safety™ is not activated at low speeds -
under 4 km/h, which is why the system does
not intervene in situations where a vehicle in
front is being approached very slowly, e.g.
when parking.
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.
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.
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.
