Radar sensor's field of vision (shown in pink)
In certain situations, the radar sensor cannot detect vehicles at close quarters,for example a vehicle that suddenlyenters the lane between your vehicle andthe target vehicle.
Small vehicles, such as motorcycles, or vehicles not driving in the center of thelane may remain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the tar-get vehicle.
WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic,weather and road conditions. The"Function" section provides informa-tion about limitations that the drivermust be aware of before using thisfeature.
• This system is designed to be a sup-plementary driving aid. It is not, how-ever, intended to replace the driver'sattention and judgement. The driver isresponsible for maintaining a safe dis-tance and speed and must intervene ifAdaptive Cruise Control does notmaintain a suitable speed or suitabledistance to the vehicle ahead.
• Maintenance of ACC components mayonly be performed by a trained andqualified Volvo technician.
WARNING
•Adaptive Cruise Control is not a colli- sion avoidance system. The driver isalways responsible for applying thebrakes if the system does not detectanother vehicle.
• Adaptive Cruise Control does not reactto people or animals, or small vehiclessuch as bicycles and motorcycles. Italso does not react to slow moving,parked or approaching vehicles, orstationary objects.
• Do not use Adaptive Cruise Control indemanding driving conditions such ascity driving or other heavy traffic situa-tions, in slippery conditions, whenthere is a great deal of water or slushon the road, during heavy rain orsnow, in poor visibility, on windingroads or on highway on- or off-ramps.
Fault tracing and actions
If the message Radar blocked See manualis displayed, this means that the radar signals from the sensor have been obstructed andthat a vehicle ahead cannot be detected. This, in turn, means that the functions of the ACC, Distance Alert, and Collision Warning

System with Auto-brake and Pedestrian Detection will not function. The table lists possible causes for this mes-sage being displayed, and suitable actions.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with the radar signals.No action possible. A very wet or snow-covered road surface may affect the function of the radar.
The surface of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed.

an audible signalThe vehicle is at a standstill and ACC will release the brakes before the parking brake engages to keep the vehicle stopped but a problem with the parking brake means that the vehicle may begin to roll. The driver will have to apply the brakes. The message will remain in the display and the audible signal will continue until the driver applies the brakes or presses the accelerator pedal.
-Below 30 km/h Only followingThis is displayed if you try to activate ACC at speeds below approx. 18 mph (30 km/h) without a vehicle ahead within range (approx. 100 ft/30 meters).

Introduction
City Safety™1
is a support system designed
to help the driver avoid low speed collisions when driving in slow-moving, stop-and-gotraffic. City Safety™ is not active if your vehicle’s speed is below approximately 2 mph(4 km/h). This means that City Safety™ willnot react if your vehicle approaches anothervehicle at very low speed, for example, whenparking. The function is active at speeds up to approximately 30 mph (50 km/h) and assiststhe driver by applying the brakes automati-cally, thereby avoiding or helping to reducethe effects of a collision. City Safety™ is designed to intervene as late as possible to help avoid unnecessary activa-tion. City Safety™ triggers brief, forceful braking if a low-speed collision is imminent. However,the system will not intervene in situationswhere the driver actively steers the vehicle orapplies the brakes, even if a collision cannotbe avoided. This is done in order to alwaysgive the driver’s actions highest priority. City Safety™ activates in situations where thedriver has not applied the brakes in time,which means that the system cannot help thedriver in all situations. City Safety™ should not be used to alter the way in which the driver operates the vehicle.The driver should never rely solely on thissystem to safely stop the vehicle. Normally, the occupants of the vehicle will not be aware of City Safety™ except whenthe system intervenes when a low-speed col-lision is imminent. If the vehicle is also equipped with the optional Collision Warning with Full Auto-brake and Pedestrian Detection system, thetwo systems interact. For more informationabout the Collision Warning with Auto-brakesystem, see page 177.
WARNING
•
City Safety™ is a supplemental aid to the driver. It can never replace thedriver’s attention to traffic conditionsor his/her responsibility for operatingthe vehicle in a safe manner.
• City Safety™ does not function in alldriving situations or in all traffic,weather or road conditions.

WARNING
•City Safety™ only reacts to vehicles traveling in the same direction as yourvehicle and does not react to smallvehicles or motorcycles or to people oranimals.
• City Safety™ is not activated whenyour vehicle is backing up.
• City Safety™ functions at speeds upto 30 mph (50 km/h). This system canhelp prevent a collision if the
differ-
ence in speed between your vehicle
and the vehicle ahead is less than9 mph (15 km/h). If the difference inspeed is greater, a collision cannot beavoided but the speed at which thecollision occurs can be reduced. Thedriver must apply the vehicle’s brakesfor full braking effect.
• City Safety™ will not intervene in apotential collision situation if the vehi-cle is being driven actively. The driveris always responsible for maintaining asafe distance to a vehicle or objectahead.
Function
Location of the laser sensor in the windshield 2
City Safety™ monitors traffic ahead of you using a laser sensor mounted in the uppersection of the windshield. If a collision isimminent, City Safety™ will automaticallyapply the brakes, which may feel like hardbraking. If the difference in speed between your vehi- cle and the vehicle ahead is more thanapproximately 9 mph (15 km/h), City Safety™alone cannot prevent a collision from takingplace. The driver must apply the brakes tohelp avoid a collision or reduce its effect. When the function activates and applies the brakes, a message will appear in the informa- tion display to indicate that the system is/hasbeen active.
NOTE
•
When City Safety™ applies the brakes, the brake lights will illuminate.
• In cases where City Safety™ has stop-ped the vehicle, the system will thenrelease the brakes. The driver mustapply the brakes to keep the vehicle ata standstill.
Using City Safety™
NOTE
The City Safety™ function is activated automatically each time the engine hasbeen switched off and restarted.
On and OffIn certain situations, it may be desirable to switch City Safety™ off, such as when drivingin close quarters where leaves, branches, etc.may obscure the hood and windshield. When the engine is running, City Safety™ can be switched off as follows:

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, remov-ing, adjusting and/or replacing anycomponents in the laser sensor mayonly be done by a trained and qualifiedVolvo service technician.
• Do not remove the laser sensor(including removal of the lenses). Alaser sensor that has been removedbelongs to laser class 3B according tostandard IEC 60825-1. Devices in laserclass 3B present a risk of injury to theeyes.
• The laser sensor’s connector must bedisconnected before the sensor isremoved from the windshield.
• The laser sensor must be mounted inplace on the windshield before con-necting the sensor’s connector.
• Do not view the laser sensor (whichemits spreading, invisible laser beams)with optical instruments from a dis-tance of less than 4 inches (100 mm).Symbols and messages in the display
When City Safety™ automatically applies the brakes, one or more of the symbols in themain instrument panel may illuminate and itsassociated message will be displayed. A text message can be erased by pressing briefly on the
