limitations
Curve Speed Assist (CSA) functionality may be reduced in certain situations. This functionis only available on some markets.
The driver should be aware of the following limitations:
Curve Speed Assist (CSA) may have lim-ited performance on small roads and indensely populated areas.
At off-ramps or intersections, CurveSpeed Assist (CSA) may temporarilyswitch off.
If the satellite navigator's 50
map data is
not updated, Curve Speed Assist (CSA)may have limited functionality.
Curve Speed Assist (CSA) functionality may be limited if the satellite navigator 50
has lost contact with the satellite system.
On new or rebuilt roads, map data may be incorrect.
The risk of reduced grip due to adverseweather or road conditions is not takeninto account when calculating suitablecornering speed.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

CauseAction
Water or snow is spraying/swirling up and blocking the radar signals or the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the cam-era/radar sensor from functioning.
There is dirt between the inside of the windshield and the cam-era/radar sensor. Consult a workshop to have the area of the windshield on the inside of the cam-era's casing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight. No action. The camera/radar sensor will reset automatically when lighting con-ditions improve.
High temperatures
If the temperature in the passenger compart- ment is very high, the camera/radar sensorwill switch off temporarily forapprox. 15 minutes after the engine is startedto protect its electronic components. Whenthe temperature has cooled sufficiently, thecamera/radar sensor will automatically restart.
Damaged windshield
NOTE
Failure to take action could result in reduced performance for the driver supportsystems that use the camera and radarunit. It could cause functions to bereduced, deactivated completely or to pro-duce an incorrect function response.
To avoid the risk of malfunction of the driver support systems that use the radar sensor, thefollowing also apply:
If there are cracks, scratches or stonechips on the windshield in front of any ofthe camera and radar sensor "windows"and this covers an area ofabout 0.5 × 3.0 mm (0.02 × 0.12 in.) ormore, contact a workshop to have the windshield replaced 54
.
Volvo advises
against repairing cracks,
scratches or stone chips in the area in front of the camera and radar sensor – theentire windshield should instead bereplaced.
Before replacing the windshield, contact a workshop 54
to verify that the right wind-
shield has been ordered and installed.
The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
If the windshield is replaced, the cameraand radar sensor must be recalibrated by a workshop 54
to help ensure proper func-
tioning of all of the vehicle's camera and radar-based systems.
Radar
Vehicle speed
The radar sensor's ability to detect a vehicle ahead is significantly reduced if the speed ofthe vehicle ahead differs greatly from yourvehicle's speed.

Limited field of vision
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle laterthan expected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles very close to your vehicle may be delayedin certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicledirectly ahead.
Small vehicles, such as motorcycles, or vehicles that are not driving in the centerof the lane may remain undetected.
In curves, the radar may detect the wrong vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossible for the radar to detect. The driver should be extra alert when driving behind vehi- cles towing low trailers when Adaptive Cruise Control
* or Pilot Assist * is activated.
Camera
Reduced visibility
Cameras have the same limitations as the human eye. In other words, their “vision" isimpaired by adverse weather conditions suchas heavy snowfall/rain, dense fog, swirlingdust/snow, etc. These conditions may reduce the function of systems that depend on thecamera or cause these systems to temporarilystop functioning. Strong sunlight, reflections from the road sur- face, ice or snow covering the road, a dirtyroad surface, or unclear lane marker lines maydrastically reduce the camera

1 - Collision warning
The driver is first alerted to the risk of an immi- nent collision. In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
Collision warning symbol on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.
City Safety can detect pedestrians, cyclists or vehicles that are stationary, are moving in thesame direction as your vehicle and are aheadof your vehicle. City Safety can also detect pedestrians, cyclists or large animals that arecrossing the road in front of your vehicle. If there is a risk of a collision with a pedestrian, large animal, cyclist or another vehicle, thedriver will be alerted with light, sound and pul-sations in the brake pedal. At lower speeds,during hard braking or if the accelerator pedalis pressed, the brake pedal pulsation warningwill not be given. The intensity of the brakepedal pulsations varies according to the vehi-cle's speed.
2 - Brake assistance
If the risk of a collision increases after the colli- sion warning, brake support will be activated. If the system determines that the pressure the driver is exerting on the brake pedal is insuffi-cient to prevent the collision, brake supportwill increase pressure.
3 - Auto-brake
The automatic braking function is activated at the last moment. If the driver has not taken evasive action by this stage and a collision is imminent, theautomatic braking function will be triggered.This occurs whether or not the driver is press-ing the brake pedal. Full braking force will beapplied to reduce the speed at impact orreduced braking effect will be applied if this issufficient to avoid the collision.
The seat belt tensioner may be activated whenthe automatic braking function is triggered. In certain situations, auto-braking may begin with a limited braking force before applyingfull braking force. If City Safety has prevented a collision, the vehicle will be kept at a standstill until thedriver takes action. If the vehicle has slowed toavoid colliding with a slower-moving vehicleahead, your speed will be reduced to that vehi-cle's speed. Auto-braking can always be cancelled if the driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the brake lights come on.
When City Safety applies the brakes, a text message will appear in the instrument panelto notify the driver that the function is/wasactivated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. Thedriver must not only rely on City Safety tobrake the vehicle.
