City Safety – Laser sensor
The laser sensor
The upper decal describes the laser beam's clas- sification and contains the following text: Invisible Laser radiation – Do not view directly with optical instruments (magnifiers) – Class 1Mlaser product. The lower decal describes the laser beam's phys- ical data and contains the text: IEC 60825-1:1993 + A2:2001. Complies with FDA performance standards for laser productsexcept for deviations pursuant to Laser NoticeNo. 50, dated July 26th, 2001 The laser beam's physical data is listed in the fol- lowing table:
Maximum pulse energy2.64 μJ
Maximum average output45 mW
Pulse length33 ns
Divergence (horizontal × vertical)28° × 12°
NOTE
The function of aftermarket laser detectors may be affected by City Safety's laser sensor.
WARNING
The laser sensor emits light when the ignition is in mode II or higher, even if City Safety ™
has been switched off.
WARNING
Eye injury may occur if any of the following points are not followed:
• It is essential that all pertinent instruc-tions be followed when handling laserinstruments. Testing, repairing, removing,adjusting and/or replacing any compo-nents in the laser sensor may only bedone by a trained and qualified Volvoservice technician.
• Do not remove the laser sensor (includingremoval of the lenses). A laser sensorthat has been removed belongs to laserclass 3B according to standard IEC60825-1. Devices in laser class 3B pres-ent a risk of injury to the eyes.

Collision warning * – function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work together to detect a pedestrian, a cyclist, stationary vehi-cles and vehicles that are moving in the samedirection as your vehicle. If there is a risk of colli-sion with a vehicle, a cyclist or a pedestrian, thedriver is alerted by a flashing red warning lightand an audible warning signal. The system isactive at speeds above 3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increase afterthe collision warning has been given, Brake Sup-port is activated. Brake Support prepares thebrake system to react quickly, and the brakes areapplied slightly. This may be experienced as alight tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support alsoincreases brake force if the system determinesthat the driver has not applied adequate pressureon the brake pedal.
Auto-brakeIf a collision is imminent and the driver has notapplied the brakes or begun to steer around thevehicle, pedestrian or a cyclist, the auto-brakefunction is activated without the driver pressingthe brake pedal. Full brake force is applied tohelp reduce the vehicle

WARNING
•In certain situations, the system cannot provide warnings or warnings may bedelayed if traffic conditions or other exter-nal factors make it impossible for theradar sensor or camera to detect apedestrian, a cyclist or a vehicle ahead.
• Warnings may not be provided if the dis-tance to the vehicle ahead is short, or ifmovements of the steering wheel/brakepedal are great, such as during activedriving.
• The sensor system has a limited range forpedestrians/cyclists and provides warn-ings and braking effect most effectively atspeeds up to 30 mph (50 km/h). For sta-tionary or slow-moving vehicles, the sys-tem functions best if your vehicle

Collision warning – troubleshooting
Fault tracing and actionsIf the message Windscreen Sensors blockedis displayed, this means that the camera isobscured and cannot detect pedestrians, cyclists, vehicles or road marker lines in front of the vehi-cle. This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, Driver Alert Con-trol, Lane Departure Warning or Lane KeepingAid will not have full functionality. The table lists possible causes for this message being displayed, and suitable actions.
CauseAction
The surface of the windshield in front of the camera is dirty or covered with ice or snow.Clean or clear the section of the windshield in front of the camera.
Fog, heavy rain or snow is interfering with the function of the camera.No action possible. Heavy precipitation may affect the function of the cam- era.
The surface of the windshield is clean but the message remains in the display.Wait a short time. It may take several minutes for the camera to register vis- ibility.
The surface between the inside of the windshield and the camera is dirty.Contact an authorized Volvo retailer or service technician to have this sur- face cleaned.
