Press My Car in the center console control
panel and go to
Settings Car settings
Driver support systems City Safety.
Select
Off.
If the engine is switched off, City Safety™ will
reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
•
Follow the same procedure as for switch-
ing City Safety™ off but select
On.
Limitations
The sensor used by City Safety™ is designed
to detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and
darkness.
WARNING
The laser sensor has certain limitations
and its function may be reduced (or it may
not function at all) in conditions such as
heavy rain or snowfall, or by dense fog or
thick, blowing dust or snow. Condensa-
tion, dirt, ice or snow on the windshield
may also interfere with the sensor’s func-
tion.
Objects such as warning flags hanging from
long objects on the roof or accessories such
as auxiliary lights or protective arches on the
front of the vehicle that are higher than the
hood may also impede the sensor’s function.
Braking distance to the vehicle ahead increa-
ses on slippery road surfaces, which may
reduce City Safety’s capacity to avoid a colli-
sion. In situations like this, the DSTC system
(see page 142) will help provide the best pos-
sible braking capacity and stability.
City Safety™ emits a laser beam and meas-
ures the way in which the light is reflected.
Therefore, vehicles or objects with low-reflec-
tive surfaces may not be detected. Normally,
the license plate and taillight reflectors give
the rear section of a vehicle ahead sufficient
reflective surfaces to be detected.
NOTE
•
Keep the windshield in front of the
laser sensor free of ice, snow, dirt, etc.
See page 163.
•
Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sen-
sor. Keep the hood free of ice and
snow.
•
Do not mount or in any way attach
anything on the windshield that could
obstruct the laser sensor.
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the
City Safety™ laser sensor is obstructed in
some way and cannot detect vehicles ahead
of you, which means that the system is not
functioning.
However, this message will not be displayed
in all situations in which the sensor is
obstructed. For this reason, the driver must
ensure that the area of the windshield in front
of the sensor is always kept clean.
The following table shows some of the situa-
tions that can cause the message to be dis-
played and suggested actions.
