Fault tracing and action
If the message Windscreen Sensors
blocked is shown in the combined instru-
ment panel it indicates that the laser sensor is
blocked and cannot detect vehicles in front of
the car. This means in turn that City Safety™
is not operational.
The
Windscreen Sensors blocked message
is not shown for all situations in which the
laser sensor is blocked. The driver must
therefore be diligent about keeping the wind-
screen and area in front of the laser sensor
clean.
The following table presents possible causes
for the message being shown, along with
suggestions for appropriate action.
Cause Action
The windscreen sur-
face in front of the
laser sensor is dirty or
covered with ice or
snow.
Clean the wind-
screen surface in
front of the sensor
from dirt, ice and
snow.
The laser sensor field
of vision is blocked.
Remove the
blocking object.
IMPORTANT
If there are cracks, scratches or stone
chips in the windscreen in front of either of
the laser sensor's "windows" and they
cover a surface of approx. 0.5 x 3.0 mm
(or larger), then a workshop must be con-
tacted for replacement of the windscreen
(see the illustration for sensor location (p.
205)) - an authorised Volvo workshop is
recommended.
Failure to take action may result in
reduced performance for City Safety™.
To avoid the risk of failed, deficient or
reduced operation for City Safety™, the
following also applies:
•
Volvo recommends that you do not
repair cracks, scratches or stone chips
in the area in front of the laser sensor -
instead, the whole windscreen should
be replaced.
•
Before replacing a windscreen, con-
tact an authorised Volvo workshop to
verify that the correct windscreen is
ordered and fitted.
•
The same type or Volvo-approved
windscreen wipers must be fitted dur-
ing replacement.
