Radar sensor
The radar sensor is designed to help detect cars or larger vehicles driving in the samedirection as your vehicle, in the same lane.
The radar sensor and its limitationsIn addition to being used by the AdaptiveCruise Control (ACC), the radar sensor is alsoused by Distance Alert (see Distance Alert –introduction (p. 198)) and Collision Warningwith Full Auto-brake and Pedestrian Detec-tion (see Collision warning – introduction(p. 209)).
WARNING
•If there is visible damage to the front grille or you suspect that the radarsensor may be damaged in any way,contact a trained and qualified Volvoservice technician as soon as possible.The radar sensor may only functionpartially (or not at all) if it is damagedor is not securely fastened in place.
• Accessories or other objects, such asextra headlights, must not be installedin front of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehi- cles ahead is impeded:
• if the radar sensor is obstructed and can- not detect other vehicles, for example in heavy rain, or if snow or other objects areobscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
•
if the speed of vehicles ahead is signifi- cantly different from your own speed.

Adaptive Cruise Control – limitations
The ACC cannot cover all driving situations and traffic, weather and road conditions.
Situations where ACC may not function optimally
WARNING
• The radar sensor has a limited field of vision. In some situations it may detecta vehicle later than expected or notdetect other vehicles at all.
• If ACC is not functioning properly,cruise control will also be disabled.

Distance Alert – introduction
Distance Alert is part of Adaptive Cruise Con- trol and is a function that provides informationabout the time interval to the vehicle ahead.
IntroductionDistance Alert is active at speeds aboveapproximately 18 mph (30 km/h). Time inter-val information is only given for a vehicle thatis driving ahead of your vehicle in the samedirection. No information is provided for vehi-cles driving toward you, moving very slowly,or at a standstill.
Amber warning light4
.
An amber warning light in the windshield glows steadily if your vehicle is closer to theone ahead than the set time interval.
NOTE
Distance Alert only monitors distance to the vehicle ahead while Adaptive CruiseControl is in standby mode or off.
WARNING
Distance Alert only indicates the distance to the vehicle ahead. It does not affect thespeed of your vehicle.

Distance Alert – limitations
Distance Alert is part of Adaptive Cruise Con- trol and is a function that provides informationabout the time interval to the vehicle ahead.
LimitationsDistance Alert uses the same radar sensorused by Adaptive Cruise Control and the Col-lision Warning system. See Adaptive CruiseControl – limitations (p. 193) for more infor-mation on the radar sensor’s limitations.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead maymake the visual warning signal in the wind-shield difficult to see.
WARNING
•Bad weather or winding roads may affect the radar sensor’s capacity todetect vehicles ahead.
• The size of the vehicle ahead, such asa motorcycle, may also make it difficultto detect. This may result in the warn-ing light illuminating at a shorter dis-tance than the one that has been set,or that the light will not come on at all.

City Safety – function
Function
Location of the laser sensor in the windshield 6
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.

City Safety – operation
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: Press My Car in the center console control
panel and go to
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.

City Safety – limitations
Limitations
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.
The sensor used by City Safety™ is designed to detect cars and other larger motor vehiclesahead of your vehicle in both daylight anddarkness. 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 stability sys-tem (see Stability system – introduction(p. 175)) will help provide the best possiblebraking 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 City Safety – function(p. 203).
• 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.

City Safety – troubleshooting
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.
CauseAction
The area of the wind- shield in front of the sen-sor is dirty or covered byice or snow.Clean the windshield orremove the ice/snow.
The laser sensor's field of view is obstructed.Remove the obstruction.
NOTE
If a crack, scratch or stone chip should occur in the section of the windshield infront the laser sensor, contact a trainedand qualified Volvo service technician torepair or replace the windshield (see theillustration showing the location of the sen-sor in City Safety – function (p. 203)). Fail-ing to do so may result in reduced CitySafety™ functionality. To help prevent limited or reduced func- tionality, please also observe the following:
• Volvo recommends that cracks, scratches or stone chips on the wind-shield in front of the laser sensorshould not
be repaired; in such cases,
the entire windshield should bereplaced.
• Before the windshield is replaced,contact a Volvo retailer to ensure thatthe correct windshield is ordered andinstalled. If the wrong type of wind-shield is used, this may cause CitySafety™ to function improperly or notat all. Volvo recommends the use ofonly Genuine Volvo ReplacementWindshields.
• When replacing windshield wipers, usethe same type or ones approved byVolvo.

WARNING
• Pedestrian and Cyclist Detection with Full Auto Brake does not work in alldriving, traffic, weather and road con-ditions. It does not react to vehiclesnot traveling in the same direction asyour vehicle.
• Pedestrian and Cyclist Detection withFull Auto Brake does not react to ani-mals.
• Warnings are only provided when therisk of collision is high. The "Function"section provides information aboutlimitations that the driver must beaware of before using Collision Warn-ing.
• Pedestrian and Cyclist Detection withFull Auto Brake will not provide awarning or brake the vehicle forpedestrians or cyclists at speedsabove 50 mph (80 km/h).
WARNING
•
Pedestrian and Cyclist Detection with Full Auto Brake will not provide awarning or brake the vehicle forpedestrians in darkness or in tunnels,even if there is street lighting in thearea.
• The auto-brake function can help pre-vent a collision or reduce the speed atimpact but the driver should alwaysapply the brakes for the best possiblebraking effect, even if auto-brake isactively applying the brakes.
• Never wait for a collision warning. Thissystem is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's atten-tion and judgement. The driver isresponsible for maintaining a safe dis-tance and speed, even when the colli-sion warning system is in use.
• Maintenance of the Pedestrian andCyclist Detection with Full Auto Brakesystem's components must only beperformed by a trained and qualifiedVolvo technician.

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, sta-tionary vehicles and vehicles that are movingin the same direction as your vehicle. If thereis a risk of collision with a vehicle, a cyclist ora pedestrian, the driver is alerted by a flash-ing red warning light and an audible warningsignal. The system is active at speeds above3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increaseafter the collision warning has been given,Brake Support is activated. Brake Supportprepares the brake system to react quickly,and the brakes are applied slightly. This maybe experienced as a light tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support alsoincreases brake force if the system deter-mines that the driver has not applied ade-quate pressure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver hasnot applied the brakes or begun to steeraround the vehicle, pedestrian or a cyclist,the auto-brake function is activated withoutthe driver pressing the brake pedal. Full brakeforce is applied to help reduce the vehicle’sspeed when the collision occurs or limitedbrake force is applied if this is sufficient toavoid the collision.
NOTE
The auto-brake and brake support func- tions are always on and cannot be turnedoff.
