Symbols and messages in the display
When City Safety™ automatically applies the
brakes, one or more of the symbols in the main instrument panel may illuminate and its associ- ated message will be displayed. A text message can be erased by pressing briefly on the
OK button on the turn signal lever.

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 – introduction Pedestrian and Cyclist Detection with Full Auto Brake is designed to assist the driver if there is arisk of a collision with a pedestrian, a cyclist, avehicle ahead that is at a standstill or one that ismoving in the same direction as your vehicle.
This system consists of the following three func- tions:
• Collision Warning
warns the driver of a
potential collision situation.
• Brake Support
helps the driver brake effi-
ciently in a critical situation.
• Auto-brake
brakes the vehicle automatically
if a collision with a pedestrian, a cyclist oranother vehicle cannot be avoided and thedriver does not apply the brakes in time orsteer around the person/vehicle. Auto-brakecan help prevent a collision or reduce thespeed at which a collision occurs.
Since Pedestrian and Cyclist Detection with FullAuto Brake is activated in circumstances wherethe driver should have begun braking muchsooner, the system will not be able to assist thedriver in all situations. This system is designed to activate as late as possible to help avoid unnecessary intervention. The system should not be used in such a way that the driver changes his/her way of operatingthe vehicle. If the driver relies entirely on the sys- tem, the chances of an accident eventually occur-ring increase considerably. The Pedestrian and Cyclist Detection with Full Auto Brake and City Safety
™ systems supple-
ment each other. See City Safety – introduction (p. 195) for detailed information about City Safety ™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations. Forthat reason, never test the Auto-brake systemby driving toward a person or object. Thiscould result in serious injury or death.

WARNING
•Pedestrian and Cyclist Detection with Full Auto Brake does not work in all driving,traffic, weather and road conditions. Itdoes not react to vehicles not traveling inthe same direction as your vehicle.
• Pedestrian and Cyclist Detection with FullAuto Brake does not react to animals.
• Warnings are only provided when the riskof collision is high. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingCollision Warning.
• Pedestrian and Cyclist Detection with FullAuto Brake will not provide a warning orbrake the vehicle for pedestrians orcyclists at speeds above 50 mph(80 km/h).
WARNING
•
Pedestrian and Cyclist Detection with Full Auto Brake will not provide a warning orbrake the vehicle for pedestrians in dark-ness or in tunnels, even if there is streetlighting in the area.
• The auto-brake function can help preventa collision or reduce the speed at impactbut the driver should always apply thebrakes for the best possible brakingeffect, even if auto-brake is actively apply-ing the brakes.
• Never wait for a collision warning. Thissystem is designed to be a supplemen-tary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance andspeed, even when the collision warningsystem is in use.
• Maintenance of the Pedestrian andCyclist Detection with Full Auto Brakesystem's components must only be per-formed by a trained and qualified Volvotechnician.

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

Collision Warning. If Pedestrian
and Cyclist Detection with Full Auto Brake is on, the system will perform a self-test each time theengine is started by briefly illuminating the warn-ing light. See My Car – introduction (p. 71) for adescription of the menu system. When the engine is switched on, the system set- ting that was being used when it was switchedoff will be the default setting.
NOTE
The auto-brake and pedestrian/cyclist detec- tion features are always on, even if the audi-ble and visual warning signals have beendeactivated.
Activating/deactivating the audible warning signal only
The audible warning signal can be activated/ deactivated by pressing MY CAR on the center
console control panel and going to

distance.
The warning distance determines the level of sensitivity used by the system. The warning dis- tance
Long provides an earlier warning. Begin by
using Long and if the system gives too many
warnings, try changing to Normal.
WARNING
• The setting Short should only be used in
situations where traffic is light and mov- ing at low speeds.
• Pedestrian and Cyclist Detection with FullAuto Brake alerts the driver to the risk ofa collision but this function cannot reducethe driver
