Preconditioning
Preconditioning is a climate function that, if possible, attempts to achieve a comfortabletemperature in the passenger compartmentbefore driving.
Preconditioning can be started immediately or started at a preset time using a timer. The function utilizes several of the vehicle's systems:
In cold weather, the parking heater heatsthe passenger compartment to a comfort-able temperature.
In warm weather, air conditioning coolsthe passenger compartment to a comfort-able temperature.
The electrically heated steering wheel
*
and seats * can be activated.
Heating for the windshield, rear windowand door mirrors are automatically acti-vated as needed.
During preconditioning in a hot climate, con-densation from the air conditions may dripunder the vehicle. This is normal.

The timer can be set to finish preconditioning at a predetermined time.
The timer can store up to 8 preset times for: A time on a particular date
A time on one or more days of the week, with or without the repeat function.
NOTE
Preconditioning is only available when the car is connected to an electrical outlet. Acharging post that is not always active, forexample because of a timer, can cause lossof function for preconditioning. If the vehicle is not connected to an electri- cal socket it is still possible in a warm cli-mate to achieve brief cooling of the pas-senger compartment by direct starting pre-conditioning.

Automatic transmission
The driver support functions can follow another vehicle at speeds from a standstill upto 200 km/h (125 mph). Pilot Assist can provide steering assistance from near-stationary speeds up to 140 km/h(87 mph). The lowest speed that can be set is 30 km/h (20 mph). When following another vehicle,ACC can monitor that vehicle's speed andslow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph).

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.

Curve Speed Assist (CSA) *48
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.

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.
54 An authorized Volvo workshop is recommended.

Road Sign Information and Sensus Navigation *
If the vehicle is equipped with Sensus Navigation*, speed-related information will be
provided in the following situations:
In cases where the speed limit is given indirectly, e.g. signs for highways or othermajor roads.
If a previously detected speed sign isdeemed to be no longer valid and no newsign has been passed.
NOTE
In certain markets, the Road Sign Informa- tion
* function is only available in combina-
tion with Sensus Navigation *.
NOTE
If a downloaded third-party app is used for navigation, there is no support for speed-related information.

Speed limit and speed camera warnings from Road Sign Information *
There are sub-functions for Road Sign Infor- mation (RSI 82
) 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 83
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
For an audible alert to be provided if the speed is exceeded, the Speed Limit
Warning function must be activated and
the Road Sign Audio Warning sub-func-
tion must be On. Audible alerts are provi-
ded if the vehicle's speed exceeds the speed displayed by Road Sign Informationin the instrument panel.
