NOTE
Keep the windscreen clean in front of the
camera and radar unit.
High temperature
At very high temperatures the camera and radar
unit can temporarily be switched off for
about 15 minutes after the engine is started so
as to protect the unit's electronics. The camera
and radar unit restarts automatically when the
temperature has fallen sufficiently.
Damaged windscreen
IMPORTANT
If a crack, scratch or stone chip in the wind-
screen in front of one of the camera and
radar unit "windows" covers an area of
approx. 0.5 x 3.0 mm or larger, a workshop
must be contacted to have the windscreen
replaced. An authorised Volvo workshop is
recommended.
Taking no action can cause reduced perform-
ance of driver support systems that use the
radar unit.
To avoid the risk of failed, deficient or
reduced operation of ™driver support sys-
tems that use the radar unit, the following
also applies:
•
Volvo recommends against repairing
cracks, scratches or stone chips in the
area in front of the camera and radar unit.
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.
DRIVER SUPPORT
IMPORTANT
When the windscreen is replaced, the camera
and radar unit must be recalibrated at the
workshop to ensure the functionality of all the
car's camera and radar-based systems. An
authorised Volvo workshop is recommended.
Maintenance
In order that the radar and camera unit shall
function correctly, the windscreen in front of the
unit must be kept clear of dirt, ice and snow, and
be cleaned regularly with water and car shampoo.
NOTE
Dirt, ice and snow covering the camera and
radar unit will reduce its function and may
prevent measurement.
