Radar sensor
The function of the radar sensor is to detect cars or larger vehicles in the same direction,in the same lane. The radar sensor is used by the following functions: •Adaptive cruise control*
• Collision Warning with Auto Brake and Pedestrian Detection*
• Distance Warning*

Radar sensor - limitations
A radar sensor (p. 197) has certain limitations, due to its limited field of vision for example. The capacity of the radar sensor to detect vehicles in front is reduced significantly:
• if the radar sensor becomes blocked and cannot detect other vehicles e.g. in heavyrain or slush, or if other objects have col-lected in front of the radar sensor.
NOTE
Keep the area in front of the radar sensor clean - see subheading "Maintenance" (p.217).
• if the speed of vehicles in front is signifi- cantly different from your own speed.
Field of visionThe radar sensor has a limited field of vision. In some situations another vehicle is notdetected, or the detection is made later thanexpected.

ACC field of vision.
Sometimes the radar sensor is late at detecting vehicles at close distances, e.g.a vehicle that drives in between the carand vehicles in front.
Small vehicles, such as motorcycles, or vehicles not driving in the centre of thelane can remain undetected.
In bends the radar sensor may detect the wrong vehicle or lose a detected vehiclefrom view.
WARNING
The driver must always be observant with regard to the traffic conditions and inter-vene when the adaptive cruise control isnot maintaining a suitable speed or suita-ble distance. The adaptive cruise control cannot handle all traffic, weather and road conditions. Read all the sections about the adaptive cruise control in the owner's manual inorder to learn about its limitations, ofwhich the driver should be aware before itis used. The driver always bears responsibility for maintaining the correct distance andspeed, even when the adaptive cruise con-trol is being used.
WARNING
Accessories or other objects such as auxil- iary lamps must not be fitted in front of thegrille.
WARNING
Adaptive cruise control is not a collision avoidance system. The driver must inter-vene if the system does not detect a vehi-cle in front. The adaptive cruise control does not brake for humans or animals, and not for smallvehicles such as bicycles and motorcy-cles. Nor for oncoming, slow or stationaryvehicles and objects. Do not use the adaptive cruise control, for example, in city traffic, in dense traffic, atjunctions, on slippery surfaces, with a lotof water or slush on the road, in heavyrain/snow, in poor visibility, on windingroads or on slip roads.
IMPORTANT
In the event of visible damage to the car's grille, or if you suspect that the radar sen-sor may be damaged:
• Contact a workshop - an authorised Volvo workshop is recommended.
The function may completely or partially disappear - or malfunction - if the grille,the radar sensor or its bracket is damagedor has loosened.

Adaptive cruise control* - fault tracing and action
The adaptive cruise control (p. 188) (ACC – Adaptive Cruise Control) helps the driver tomaintain an even speed and a safe distancefrom the vehicle ahead. If the combined instrument panel shows the message
Radar blocked See manual this means that the radar signals from the radar sensor (p. 197) are blocked and that vehiclesin front of the car cannot be detected. In turn this means that - apart from Adaptive Cruise Control - Distance Warning (p. 202)and Collision Warning (p. 212) with AutoBrake are not operating either.
The following table presents examples ofpossible causes for a message being shownalong with the appropriate action:
CauseAction
The radar surface in the grille is dirty or covered with ice or snow.Clean the radar surface in the grille from dirt, ice and snow.
Heavy rain or snow blocking the radar signals.No action. Sometimes the radar does not work during heavy rain or snowfall.
Water or snow from the road surface swirls up and blocks the radar signals.No action. Sometimes the radar does not work on a very wet or snowy road surface.
The radar surface has been cleaned but the message remains.Wait. It could take several minutes for the radar to sense that it is no longer blocked.

Adaptive cruise control* - symbols and messages
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain an even speed and a safe distance from the vehi-cle ahead. Sometimes the adaptive cruisecontrol may display a symbol and/or text
message. Here are several examples - followthe recommendation given if appropriate:
SymbolMessageSpecification
The symbol is GREENThe car maintains the stored speed.
The symbol is WHITEAdaptive cruise control is set to standby mode.
Standard cruise control is selected manually.
DSTC Normal to enable CruiseThe adaptive cruise control cannot be activated until the Stability and Traction Control system (DSTC) (p. 175) has been set in Normal mode.
Cruise control Cancel- ledThe adaptive cruise control has been deactivated - the driver has to regulate the speed himself.
Cruise control Unavail- ableThe adaptive cruise control cannot be activated. This could be due to:
• brake temperature is high
• the radar sensor is blocked by e.g. wet snow or rain.
Radar blocked See manualThe adaptive cruise control is temporarily disengaged.
• The radar sensor is blocked and cannot detect other vehicles. For example, in the event of heavy rain or if slush has collected in front of the radar sensor.
The driver can then choose to switch to (p. 196) normal Cruise control (CC) - a text message provides information on appropriate alternatives. Read about radar sensor limitations (p. 197).

The same symbol is also shown when adap- tive cruise control is activated.
NOTE
The higher the speed the longer the calcu- lated distance in metres for a given timeinterval. The set time interval is also used by the function adaptive cruise control (p. 189). Only use the time intervals permitted by local traffic regulations.

Distance Warning* - limitations (p. 203)
Distance Warning* - limitations
Distance Warning (Distance Alert) is a function that informs the driver about the distance tovehicles in front. The function uses the sameradar sensor as the Adaptive cruise control (p.188) and Collision warning with auto brake (p.212), has some limitations.
NOTE
Strong sunlight, reflections or strong varia- tions in light intensity, as well as wearingsunglasses, could mean that the warninglight in the windscreen cannot be seen. Poor weather or winding roads could affect the radar sensor's capacity to detectvehicles in front. The size of other vehicles could also affect detection capacity, e.g. motorcycles. Thiscould mean that the warning lamp illumi-nates at a shorter distance than the settingor that the warning is temporarily absent. Extremely high speeds can also cause the lamp to illuminate at a shorter distancethan that set due to limitations in sensorrange.
For further information on radar sensor limita- tions, see Radar sensor - limitations (p. 197)and (p. 218).

City Safety™
City Safety™ is a function for helping the driver to avoid a collision when driving inqueues, amongst other things, when changesin the traffic ahead, combined with a lapse inattention, could lead to an incident. The City Safety™ function is active at speeds under 50 km/h and it helps the driver by auto-matically braking the car in the event of immi-nent risk of collision with vehicles in front,should the driver not react in time by brakingand/or steering away. City Safety™ is activated in situations where the driver should have started braking earlier,which is why it cannot help the driver in everysituation. City Safety™ is designed to be activated as late as possible in order to avoid unnecessaryintervention. City Safety™ must not be used as an excuse for the driver to change his/her driving style. Ifthe driver solely relies on City Safety™ to dothe braking, there will be a collision sooner orlater. The driver or passengers normally only notice City Safety™ if a situation arises where thecar is extremely close to being in a collision. If the car is also equipped with Collision Warning with Auto Brake (p. 212)* these twosystems complement each other.IMPORTANT
Maintenance and replacement of City Safety™ components must only be per-formed by a workshop - an authorisedVolvo workshop is recommended.
WARNING
City Safety™ does not engage in all driv- ing situations or traffic, weather or roadconditions. City Safety™ does not react to vehicles driving in a different direction from the car,to small vehicles and motorcycles or tohumans and animals. City Safety™ can prevent collision at a speed difference of less than 15 km/h - ata higher speed difference, it is only possi-ble to reduce collision speed. In order toobtain full brake function, the driver mustdepress the brake pedal. Never wait for City Safety™ to engage. The driver always bears responsibility formaintaining the proper distance andspeed.

City Safety™ - function
City Safety™ detects the traffic in front of the car with a laser sensor fitted in the top edgeof the windscreen. If there is an imminent riskof collision, City Safety™ will automaticallybrake the car, which may be experienced assudden braking.

.
If the speed difference is 4-15 km/h in relation to the vehicle in front then City Safety™ cancompletely prevent a collision. City Safety™ activates a short, sharp braking and stops the car in normal circumstances,just behind the vehicle in front. For most dri-vers this is well outside normal driving styleand may be experienced as being uncomfort-able. If the difference in speed between the vehi- cles is greater than 15 km/h then CitySafety™ may not prevent the collision on itsown. To obtain full brake force, the drivermust depress the brake pedal. This couldthen make it possible to prevent a collision,even at speed differences above 15 km/h. When the function is activated and brakes,the combined instrument panel shows a textmessage to the effect that the function is/hasbeen active.
NOTE
When City Safety™ brakes, the brake lights come on.

On and Off
NOTE
The City Safety™ function is always switched on after the engine has beenstarted via key position
I and II (p. 70).
In certain situations, it may advisable to disa- ble City Safety™, e.g. where leafy branchescould sweep over the bonnet and/or wind-screen. After starting the engine City Safety™ can be deactivated as follows: The function can beactivated/deactivated in the menu system MY
CAR . For a description of the menu system,
see MY CAR (p. 103). However, the function will be enabled the next time the engine is started, regardless ofwhether the system was enabled or disabledwhen the engine was switched off.
