NOTE
•
Keep the windscreen surface in front of
the laser sensor free from ice, snow and
dirt (see the illustration for sensor loca-
tion (p. 225)).
•
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.
Fault tracing and action
If the message Windscreen sensors blocked
See manual 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 See
manual message is not shown for all situations
in which the laser sensor is blocked. The driver
must therefore be diligent about keeping the
windscreen and area in front of the laser sensor
clean.
The following table presents possible causes for
the message being shown, along with sugges-
tions for appropriate action.
Cause Action
The windscreen surface
in front of the laser sen-
sor 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 block-
ing 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 contacted for replacement
of the windscreen (see the illustration for
sensor location (p. 225)) - 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 fol-
lowing 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, contact
an authorised Volvo workshop to verify
that the correct windscreen is ordered
and fitted.
•
The same type or Volvo-approved wind-
screen wipers must be fitted during
replacement.
