Distance Alert* limitations
Distance Alert uses the same radar sensor asAdaptive Cruise Control* and has several limita-tions.

WARNING
•The radar sensor has a limited field ofvision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
•The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
•The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
•Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
•Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see.
WARNING
•Poor weather or winding roads can affectthe radar sensor's capacity to detect vehi-cles ahead.
•A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
•High speeds may also result in the warn-ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
For additional information, see also the article"Radar sensor limitations."

Adaptive Cruise Control (ACC)*
ACC is an optional system designed to assistthe driver by maintaining a set speed or a settime interval to the vehicle ahead.
ACC helps provide more relaxed driving on longtrips on highways or other major roads in a rela-tively even flow of traffic.
The camera and radar sensor monitor the distance tothe vehicle ahead (generic illustration - certain detailsmay vary from model to model)
The driver sets that desired speed and time inter-val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed.
ACC is designed to follow a vehicle ahead in thesame lane and maintain a time interval to that

Passing Assistance with AdaptiveCruise Control or Pilot Assist-2
ACC or Pilot Assist can assist the driver whenpassing other vehicles.

How passing assistance works
When ACC or Pilot Assist is following anothervehicle and the driver indicates that he/she isabout to pass that vehicle by using the left turnsignal, ACC or Pilot Assist will begin acceleratingtoward the vehicle ahead before your vehicle hasmoved into the passing lane.
The function will then delay a speed reduction toavoid early braking as your vehicle approachesthe slower-moving vehicle.
The function is active until your vehicle haspassed the other vehicle.

WARNING
Be aware that this function may be activatedin situations other than when passing a vehi-cle, such as if the turn signal is used to indi-cate a lane change or to indicate a turn. Thevehicle will accelerate briefly.

Using passing assistance
To activate passing assistance:
•Your vehicle (ACC or Pilot Assist) must befollowing another vehicle (the target vehicle).
•Current speed must be at least approx.45 mph (70 km/h ).
•The speed set for ACC or Pilot Assist mustbe high enough to safely pass the vehicleahead.
Starting passing assistance
To start a passing assistance sequence:
•Activate the left turn signal.

Passing assistance limitations
WARNING
The driver should be prepared for suddenchanges when passing assistance is used. Incertain cases, there may be undesired accel-eration.
Certain situations should be avoided, such as:
•If the vehicle is approaching an exit to theleft or a left turn.
•If the vehicle ahead slows down beforeyour vehicle has moved into the passinglane.
•Traffic in the passing lane slows down.
Passing assistance in these situations can bedeactivated by putting ACC or Pilot Assist instandby mode.

Changing target vehicles andautomatic braking with AdaptiveCruise Control (ACC)
At certain speeds, Adaptive Cruise Control canchange target vehicles and automatically applythe brakes.
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta-tionary vehicle ahead
When ACC is actively following another vehicle atspeeds under 20 mph (30 km/h) and changestargets from a moving vehicle to a stationary one,the system will brake for the stationary vehicle.

Pilot Assist*
Pilot Assist helps the driver keep the vehiclebetween a traffic lane's side marker lines as wellas helping to maintain a set time interval (dis-tance) to a vehicle ahead.
There are two versions of Pilot Assist: PilotAssist-1 and Pilot Assist-2. The following illus-trations provide help in determining the versionthat is in your vehicle.

Pilot Assist-1
Vehicles with Pilot Assist-1have this symbol in the instru-ment panel.

Pilot Assist-2
Vehicles with Pilot Assist-2have this symbol in the instru-ment panel.

Related information
•Pilot Assist-1* (p. 295)
•Pilot Assist-2* (p. 305)
Pilot Assist-1*
The Pilot Assist feature helps keep the vehicle inits current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
Function
The vehicle's camera monitors the traffic lane'sside marker lines and a distance monitor helpsmaintain the set time interval to the vehicleahead.
Pilot Assist helps provide more relaxed driving inheavy, slow-moving traffic at speeds up to30 mph (50 km/h) on highways and major roads.
Function overview
Windshield module containing the camera/radar sensor
Monitoring distance
Monitoring side marker lines
The driver sets the desired time interval to thevehicle ahead. Pilot Assist monitors that vehicleand the traffic lane's side market lines using thecamera and radar sensor mounted in the upper,center section of the windshield. It helps maintainthe set time interval by automatically adjustingspeed and by providing steering assistance tohelp keep your vehicle in the lane.
Pilot Assist's steering assistance is based onmonitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canalways override Pilot Assist and steer the vehicleto e.g., change lanes, etc.

DRIVER SUPPORT
296
If the camera and radar sensor cannot detect thelane's side marker lines or a vehicle ahead, PilotAssist goes into standby mode.
When Pilot Assist is in standby mode and yourvehicle comes too close to the vehicle ahead, thedriver will be alerted by the Distance Alert func-tion.

WARNING
•Pilot Assist is designed to be a supple-mentary driving aid and cannot cover alldriving situations, traffic, weather and/orroad conditions.
•The driver should be familiar with all ofthe information in this article regardingPilot Assist, including its limitations.
•Pilot Assist is not intended to replace thedriver's attention and judgement.
•Pilot Assist must only be used wherethere are clearly visible traffic lane sidemarker lines on both sides of the currenttraffic lane. In other circumstances thereis an increased risk of collision with sur-rounding obstacles that are not detectedby the system.
•The driver is always responsible for steer-ing the vehicle and maintaining a suitablespeed and distance to the vehicle aheadand must intervene if necessary, even ifPilot Assist is being used.
Pilot Assist is designed to regulate speedsmoothly but in situations calling for fast braking,the driver must apply the brakes. This applies tosituations where there are considerable differen-ces in speed or if the vehicle ahead brakes sud-denly. Due to the limitations of the camera andradar sensor, the system may apply the brakes inyour vehicle suddenly or not at all.
•The default speed for Pilot Assist is preset toapprox. 30 mph (50 km/h) and cannot bechanged. If the vehicle ahead increasesspeed to over 30 mph (50 km/h) and pullsaway from your vehicle, Pilot Assist will gointo standby mode.

NOTE
•Pilot Assist maintenance should only becarried out by a trained and qualifiedVolvo service technician.
•Pilot Assist regulates your vehicle'sspeed using the accelerator pedal andthe brakes. Please be aware that theremay be a faint sound from the brakeswhen the system is using them.
WARNING
•Pilot Assist is not a collision avoidancesystem. The driver must react if the sys-tem does not detect another vehicle.
•Pilot Assist does not react to people, ani-mals, stationary objects, small vehicles(such as bicycles and motorcycles), lowtrailers and slow moving, parked orapproaching vehicles.
•Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.

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 .
