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 pro-
jecting load, or accessories such as auxiliary
lamps and bull bars that are higher than the bon-
net 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 distance is
extended, which may reduce the capacity of City
Safety to avoid a collision. In such situations the
ABS
13
and ESC
14
systems will provide best pos-
sible braking force with maintained stability.
When your own car is reversing, City Safety is
temporarily deactivated.
City Safety is not activated at low speeds - below
4 km/h (3 mph), which is why the system does
not intervene in situations where a vehicle in front
is being approached very slowly, e.g. when park-
ing.
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 collision is unavoidable.
When City Safety has prevented a collision with a
stationary object the car remains stationary for a
maximum of 1.5 seconds. If the car is braked for
a vehicle in front that is moving, 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.
