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 City
Safety – function (p. 203).
•
Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sensor.
Keep the hood free of ice and snow.

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 situations
that can cause the message to be displayed and
suggested actions.
Cause Action
The area of the windshield
in front of the sensor is
dirty or covered by ice or
snow.
Clean the wind-
shield or remove
the ice/snow.
The laser sensor's field of
view is obstructed.
Remove the
obstruction.
NOTE
If a crack, scratch or stone chip should occur
in the section of the windshield in front the
laser sensor, contact a trained and qualified
Volvo service technician to repair or replace
the windshield (see the illustration showing
the location of the sensor in City Safety –
function (p. 203)). Failing to do so may result
in reduced City Safety™ functionality.
To help prevent limited or reduced functional-
ity, please also observe the following:
•
Volvo recommends that cracks, scratches
or stone chips on the windshield in front
of the laser sensor should not be
repaired; in such cases, the entire wind-
shield should be replaced.
•
Before the windshield is replaced, con-
tact a Volvo retailer to ensure that the
correct windshield is ordered and instal-
led. If the wrong type of windshield is
used, this may cause City Safety™ to
function improperly or not at all. Volvo
recommends the use of only Genuine
Volvo Replacement Windshields.
•
When replacing windshield wipers, use
the same type or ones approved by Volvo.
