City Safety – troubleshooting
TroubleshootingIf 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. Forthis reason, the driver must ensure that the areaof the windshield in front of the sensor is alwayskept clean. The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
Cause Action
The area of the windshield in front of the sensor isdirty or covered by ice orsnow. Clean the wind-shield or removethe ice/snow.
The laser sensor's field ofview is obstructed. Remove theobstruction.
NOTE
If a crack, scratch or stone chip should occur in the section of the windshield in front thelaser sensor, contact a trained and qualifiedVolvo service technician to repair or replacethe windshield (see the illustration showingthe 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, scratchesor 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 thecorrect 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 GenuineVolvo Replacement Windshields.
• When replacing windshield wipers, usethe same type or ones approved by Volvo.
