Activating ACC (putting it in active
mode and setting a speed)
Before ACC can be put in active mode:
•The driver's seat belt must be buckled andthe driver's door must be closed.
•There must be a vehicle ahead (a target vehi-cle) within a reasonable distance or yourvehicle's current speed must be at least9 mph (15 km/h).
–With the symbol displayed (ACC is in
standby mode), press the button (1) onthe left-side steering wheel keypad.
>This puts ACC in active mode and setsthe vehicle's current speed, which is indi-cated by digits in the center of the speed-ometer.
The time interval to the vehi-cle ahead will only be shownwhen two vehicles are dis-played.
A speed interval will also beindicated:
•The higher speed is the one set in ACC
•The lower one is the speed of the vehicleahead (the target vehicle).

Setting an Adaptive Cruise Controltime interval
ACC makes it possible to set various time inter-vals to the vehicle ahead.
Different time intervals to thevehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds.
The same symbol appears if Distance Alert isactivated.
•If the symbol shows two vehicle's, ACC isactively following the vehicle ahead (a targetvehicle).
•If only one vehicle is displayed, ACC is notactively following another vehicle.

Changing a time interval
Controls for setting a time interval
Reduce the time interval
Increase the time interval
Distance/time indicator
–Press buttons (1) or (2) to reduce orincrease the time interval.
>The distance/time indicator (3) shows thecurrent time interval.
In order to follow the vehicle ahead as smoothlyas possible, ACC allows the time interval to varyconsiderably in certain situations. At low speeds,when the distance to the vehicle ahead is short,ACC increases the time interval slightly.
•If ACC does not seem to react when it is putin active mode, this may be because the set
time interval to the vehicle ahead does notallow an increase in speed.
•The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
•Only use time intervals permitted by localtraffic regulations.

WARNING
•Only use a time interval that is suitable incurrent traffic conditions.
•A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Adaptive Cruise Control (ACC) -troubleshooting
If this symbol is displayed in the instru-ment panel and the messageWindscreen sensor Sensorblocked, see Owner's manualappears, the ACC radar sensor is blocked andcannot detect vehicles ahead.
This message also indicates that the followingsystems may have reduced functionality:
•Distance Alert
•City Safety
•Driver Alert Control
•Pilot Assist
•Lane Keeping Aid (LKA)
•Road Sign Information (RSI)
The following table lists possible causes for this message being displayed and suitable actions:
CauseAction
The windshield in front of the radar is dirty or covered with snow/ice.Clean/clear the windshield in front of the radar.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with theradar signals.No action possible. A very wet or snow-covered road surface may affect thefunction of the radar.
The windshield in front of the radar is clean but the message remains in thedisplay.Wait a short time. It may take several minutes for the radar to detect that it isno longer obstructed.
A text message can be erased by briefly pressingthe O button on the right-side steering wheelkeypad. If the message recurs, contact a trainedand authorized Volvo service technician orretailer.

Head-up-display *
A flashing symbol alerts the driver
If the vehicle is equipped with a head-up display,a flashing symbol in the windshield will alert thedriver.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.
WARNING
Pilot Assist only provides warnings for vehi-cles that its radar sensor and camera havedetected. For this reason, a warning may begiven later than expected or not at all. Thedriver should never wait for a warning beforeapplying the brakes.

Prerequisites
The prerequisites for activating Pilot Assist are:
•The vehicle ahead must be within a reasona-ble (detectable) distance
•The camera must be able to clearly detectthe traffic lane's side marker lines
•The vehicle's speed must be under approx.30 mph (50 km/h).
A WHITE symbol indicates thatPilot Assist has been selected.
In other cases, the WHITEarrow pointing to the right indi-cates that the system is availa-ble.
A YELLOW symbol with a flashing WHITE arrowindicates that the system is about to shift intostandby mode.
With ACC in standby mode:
1.Tap ▶ (6).
>The symbol will be displayed and PilotAssist will go into standby mode.
2.Press the button (2) on the left-sidesteering wheel keypad.
>Pilot Assist will go into active mode.

WARNING
Pilot Assist is not a collision avoidance sys-tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle.
Do not use Pilot Assist in demanding drivingconditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps.
In certain situations, it may be difficult for PilotAssist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
•the lane's side market lines are missing,badly faded or cross each other.
•the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
•there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
•the lane is narrow or winding.
•the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that PilotAssist has the following limitations:
•High curbs, barriers and temporary obsta-cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
•The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
•Pilot Assist does not "see" pedestrians,animals, etc.
•Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.

Hands on the steering wheel
Pilot Assist only functions when the driver'shands are on the steering wheel, which is con-tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound.
If the driver does not return his/her hands to thesteering wheel after the audible signal, PilotAssist will go into standby mode and must be
reactivated by pressing .
