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

SymbolMessageDescription
-Cruise control Cancel- ledACC has been automatically switched off. The driver has to regulate the vehicle’s speed/distance to the vehicle ahead.
-Cruise control Unavail- ableACC cannot be put in active mode. This may be due to: • high brake temperature
• the radar sensor is obstructed (by heavy rain, snow, etc.)
Radar blocked See manualACC has been temporarily disconnected because the radar is obstructed in some way and cannot detect other vehicles. In this situation, the driver can switch to standard cruise control, see page 147See page 149 for information on the radar sensor’s limitations.
-Cruise control Service requiredACC is not functioning. Contact a trained and qualified Volvo service technician.
-Press Brake To hold +
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).

SettingsCar settings
Driver support systemsCity Safety.
Select
Off.
If the engine is switched off, City Safety™ will reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
• Follow the same procedure as for switch- ing City Safety™ off but select
On.
Limitations
The sensor used by City Safety™ is designed to detect cars and other larger motor vehiclesahead of your vehicle in both daylight anddarkness.
WARNING
The laser sensor has certain limitations and its function may be reduced (or it maynot function at all) in conditions such asheavy rain or snowfall, or by dense fog orthick, blowing dust or snow. Condensa-tion, dirt, ice or snow on the windshieldmay also interfere with the sensor’s func-tion.
Objects such as warning flags hanging from long objects on the roof or accessories suchas auxiliary lights or protective arches on thefront of the vehicle that are higher than thehood may also impede the sensor’s function. Braking distance to the vehicle ahead increa- ses on slippery road surfaces, which mayreduce City Safety’s capacity to avoid a colli-sion. In situations like this, the DSTC system(see page 136) will help provide the best pos-sible braking capacity and stability. City Safety™ emits a laser beam and meas- ures the way in which the light is reflected.Therefore, vehicles or objects with low-reflec-tive surfaces may not be detected. Normally,the license plate and taillight reflectors givethe rear section of a vehicle ahead sufficientreflective surfaces to be detected.
NOTE
•Keep the windshield in front of the laser sensor free of ice, snow, dirt, etc.See page 157.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sen-sor. Keep the hood free of ice andsnow.
• Do not mount or in any way attachanything on the windshield that couldobstruct the laser sensor.
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the City Safety™ laser sensor is obstructed insome way and cannot detect vehicles aheadof you, which means that the system is notfunctioning. However, this message will not be displayed in all situations in which the sensor isobstructed. For this reason, the driver mustensure that the area of the windshield in frontof the sensor is always kept clean. The following table shows some of the situa- tions that can cause the message to be dis-played and suggested actions.

Collision warning with Full Auto-brake and Pedestrian Detection*
04
166* Option/accessory, for more information, see Introduction.
NOTE
If warnings are given too frequently, the warning distance can be reduced (seepage 164). This causes the system to pro-vide later warnings, which decreases thetotal number of warnings provided.
WARNING
• The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the CollisionWarning system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.
The camera’s limitationsThe camera is used by Collision Warning with Auto-brake, Driver Alert Control (seepage 170), and Lane Departure Warning (seepage 173).
NOTE
•To help protect the camera in very hot conditions, it may be temporarilyswitched off for approximately 15minutes after the engine has beenstarted.
• Keep the section of the windshield infront of the camera clean and free ofice, snow, or condensation.
WARNING
•The camera has the same limitations as the human eye. In other words, its“vision is impaired” by adverseweather conditions such as heavysnowfall, dense fog, etc. These condi-tions may reduce the function of sys-tems that depend on the camera orcause these systems to temporarilystop functioning.
• Never place any objects, decals, etc.,on the windshield in front of the cam-era. This could reduce or block thecamera’s function, and could causeone or more of the systems that utilizethe camera to stop functioning.
• Strong sunlight, reflections from theroad surface, ice or snow covering theroad, a dirty road surface, or unclearlane marker lines may drasticallyreduce the camera’s capacity todetect the side of a lane, a pedestrianor another vehicle.

* Option/accessory, for more information, see Introduction.167
Pedestrians
The system cannot identify all pedestrians
The Collision Warning system can only iden- tify and detect a pedestrian who is standingupright. This person can be standing still,walking or running. This means that the system has to be able to identify a person's head, arms, shoulders,legs, the upper and lower parts of the bodyand a person's pattern of movement whenwalking or running. If parts of the body are not visible to the cam- era, the system cannot detect the pedestrian. The following conditions apply:
• In order to detect a pedestrian, the sys- tem must have a full view of the person'sentire body and the person must be atleast 32 in. (80 cm) tall.
• The system cannot detect a pedestriancarrying a large object.
• The camera's capacity to see a pedes-trian at dawn or dusk is limited, much asit is for the human eye.
• The camera's function is deactivated andwill not detect a pedestrian in darkness orin tunnels, even if there is street lighting inthe area.
WARNING
• Collision Warning with Full Auto-brake and Pedestrian Detection is designedto be a supplementary driving aid. It isnot, however, intended to replace thedriver's attention and judgement. Thedriver is always responsible for operat-ing the vehicle in a safe manner.
• The system cannot detect all pedes-trians in all situations, such as in dark-ness/at night and cannot detect parti-ally hidden pedestrians, people whoare less than approx. 32 in. (80 cm)tall, or people wearing clothing thatobscures the contours of their bodies.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, vehicles or road marker lines infront of the vehicle. This, in turn, means that Collision Warning with Full Auto-brake and Pedestrian Detec-tion, Lane Departure Warning, and DriverAlert Control will not have full functionality. The table lists possible causes for this mes- sage being displayed, and suitable actions.
