However, the function (p. 217) 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 (p. 220) emits laser light
even when City Safety™ is disabled man-
ually.
To enable City Safety™ again:
•
Follow the same procedure as for disa-
bling, but select the
On

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 has a number of
limitations.
The sensor has poorer functionality - or none
at all - in e.g. heavy snowfall or rain, dense
fog, dust storms or white-out situations. Mist-
ing, 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 light 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 and DSTC 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.
NOTE
•
Keep the windscreen surface in front
of the laser sensor (p. 220) free from
ice, snow and dirt. For an illustration of
sensor location, see City Safety™ -
function (p. 217).
•
Do not affix or mount anything on the
windscreen in front of the laser sensor
•
Remove ice and snow from the bonnet
- snow and ice must not exceed a
height of 5 cm.
