Symbol for Distance Alert on the windshield with head-up display
In vehicles equipped with a head-up display, a symbol will be displayed on the windshield aslong as the time interval to the vehicle aheadis shorter than the set time interval. However, the
Show Driver Support function must be
activated under Settings in the vehicle's menu system. Distance Alert is active at speeds above 30 km/h (20 mph) and only reacts for vehicles ahead moving in the same directionas your vehicle. No distance information isprovided for oncoming, slow-moving or sta-tionary vehicles.
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.
NOTE
Distance Alert is deactivated while Adap- tive Cruise Control
* or Pilot Assist * is
active.
WARNING
Distance Alert only reacts of the time inter- val to the vehicle ahead is shorter than thepreset value – vehicle speed is not affec-ted.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.

Setting time interval to the vehicle ahead The time interval to the vehicle ahead can be set for the functions Adaptive Cruise Control *,
Pilot Assist * and Distance Alert *.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, thelonger the time interval. Onebar represents an interval of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasona-ble distance.
NOTE
When the symbol in the instrument panel shows two vehicles, ACC is following thevehicle ahead at a preset time interval. When only one vehicle is shown, there is no vehicle ahead within a reasonable dis-tance.
Controls for setting a time interval.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the current time interval. In order to help your vehicle follow the vehicle ahead as smoothly and comfortably as possi-ble, Adaptive Cruise Control allows the timeinterval to vary noticeably in certain situations.At low speeds, when the distance to the vehi-cle ahead is short, Adaptive Cruise Controlincreases the time interval slightly.
NOTE

The greater the vehicles' speed, the greater the distance between them fora set time interval.
Only use the time intervals permittedby local traffic regulations.
If driver support does not seem torespond with a speed increase whenactivated, it may be because the timeinterval to the vehicle ahead is shorterthan the set time interval.
WARNING
Only use a time interval suitable for the current traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Curve Speed Assist (CSA) *44
Curve Speed Assist can help the driver
reduce speed before sharp turns if the preset speed for the driver support function Adap- tive Cruise Control * or Pilot Assist * is deter-
mined to be too high.
This assessment is performed using informa- tion from map data in the vehicle's navigation system, Sensus Navigation *. After the turn,
the vehicle will resume the previously set speed.
As the function reduces thevehicle's speed, this symbolwill be displayed in the instru-ment panel.
The driver can cancel the function at any time by braking or using the accelerator pedal.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.

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 50
.
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 50
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 50
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.
50 An authorized Volvo workshop is recommended.

) that can alert the driver if the
speed limit has been exceeded or if there are speed cameras nearby.
Example of speed camera and speed limit informa- tion in the instrument panel.
Speed Limit WarningWhen Speed Warning is acti- vated, the symbol for the cur-rent speed limit in the instru- ment panel 79
will flash tem-
porarily if that speed is excee- ded.
The driver can be alerted if the vehicle is exceeding a detected speed limit and isapproaching a speed camera.
Speed Limit Warning warns the driver if the
vehicle's speed has exceeded the applicable speed limit or the preset Speed Limiter speed.The warning will be repeated once afterabout 1 minute in that speed limit area if thedriver does not slow down. A new warning and message indicating that the speed limit has been exceeded will be pro-vided only when the vehicle has entered anew/different speed limit area.
NOTE
