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 × 3.0 mm (0.02 × 0.12 in.) or
larger, a workshop must be contacted to have
the windscreen replaced – an authorised
Volvo workshop is recommended.
If not rectified it can lead to reduced perform-
ance for the driver support systems that use
the camera and radar unit.
This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.
To avoid the risk of failed, deficient or
reduced operation of driver support systems
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.
DRIVER SUPPORT
•
The same type or Volvo-approved wind-
screen wipers must be fitted during
replacement.
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.
