* Option/accessory.301
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.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
Pilot Assist regulates speed by acceleratingand braking. It is normal for the brakes to emita slight sound when they are being used toadjust speed. Pilot Assist attempts to smoothly regulate speed. The driver must apply the brakes in sit-uations requiring immediate braking. Forexample, when there are great differences in speed between vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the camera and radar sensor, braking may occur unexpectedly or not at all. Pilot Assist attempts to follow a vehicle ahead in the same lane and maintain a time intervalto that vehicle set by the driver. If the radarsensor does not detect a vehicle ahead, it willinstead maintain the speed set by the driver.This will also happen if the speed of the vehi-cle ahead exceeds the set speed for your vehi-cle.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.
In curves and forks in the roadPilot Assist is designed to interact with the driver. The driver should never wait for steer-ing assistance from Pilot Assist, but insteadshould always be ready to increase his or herown steering efforts, particularly in curves.
When the vehicle is approaching an off-ramp or a fork in the road, the drivershould steer toward the desired lane toindicate to Pilot Assist the desired direc-tion of travel.
Pilot Assist strives to keep the vehicle in the center of the lane
When Pilot Assist provides steering assis- tance, it strives to position the vehicle in thecenter of the lane between the lane markings.To make the driving experience as smooth aspossible, the driver should permit the vehicleto find good positioning. The driver shouldcheck that the vehicle is positioned safely inthe lane and can always adjust the vehicle'sposition by applying more force to the steeringwheel. If Pilot Assist does not position the vehicle appropriately in the lane, the driver shouldturn off Pilot Assist or switch to Adaptive Cruise Control
*.
Hands on the steering wheelPilot Assist only functions if the driver's hands are on the steering wheel.
If Pilot Assist detects that thedriver's hands are not on thesteering wheel, a symbol andtext message will appear toinstruct the driver to activelysteer the vehicle.
If the driver's hands are still not detected on the steering wheel after a few seconds havepassed, the instructions to actively steer thevehicle will be repeated, accompanied by anaudible signal.

NOTE
Note that the Pilot Assist function only works when the driver's hands are on thesteering wheel.
Additional markings in the instrument panel
Pilot Assist will only regulate the time interval to the vehi-cle ahead when the distancesymbol shows a vehicle (1)over the steering wheel sym-bol.
Pilot Assist's steering assistance is only activewhen the steering wheel symbol (2) changesfrom GRAY to GREEN.
A speed interval will be marked at the same time. The higher speed is the stored speed for your vehicleand the lower speed is thespeed of the vehicle ahead
(target vehicle).

Temporarily deactivating steering assistance with Pilot Assist *44
Pilot Assist steering assistance can be tem- porarily deactivated and reactivated withoutprior warning.
When the turn signals are used, Pilot Assist's steering assistance will be temporarily deacti-vated. When the turn signal is switched off,steering assistance will be automatically reac-tivated if the traffic lane's side markings canstill be detected. If Pilot Assist cannot clearly interpret the lane's side marker lines or if the camera/radarsensor is unable for some other reason toclearly interpret the lane, Pilot Assist will tem-porarily deactivate steering assistance. How-ever, the speed and distance warnings willremain active. Steering assistance will resumewhen the side marker lines can once again beinterpreted. In these situations, the driver maybe alerted through slight vibrations in thesteering wheel that steering assistance is tem-porarily deactivated.

limitations
Pilot Assist functionality may be reduced in certain situations.
Pilot Assist is a driver support function designed to simplify driving and assist thedriver in many situations. However, the driveris always responsible for maintaining a suita-ble distance to vehicles or objects around itand ensuring that the vehicle is correctly posi-tioned in the traffic lane.
WARNING
In some situations, Pilot Assist may have trouble helping the driver properly or maybe deactivated automatically – we adviseagainst using Pilot Assist in such cases.Examples of such situations include:
the lane markings are worn, missing or cross each other.
lane division is unclear, for example,when the lanes divide or merge or atexits or when there are multiple sets ofmarkings.
edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edgesor strong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,snow or fog or slush or reduced visibil-ity with poor light conditions, back-lighting, wet road surface, etc.
The driver should also note that Pilot Assist has the following limitations:
High curbs, roadside barriers, tempo- rary obstacles (traffic cones, safety bar-riers, etc.) are not detected. Alterna-

tively, they may be detected incorrectly as lane markings, with a subsequentrisk of contact between the vehicle andsuch obstacles. The driver is responsi-ble for ensuring that the vehicle main-tains a suitable distance from suchobstacles.
The camera and radar sensors do nothave the capacity to detect all oncom-ing objects and obstacles in trafficenvironments, e.g. potholes, stationaryobstacles or objects that completely orpartially block the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The recommended steering input islimited in force, which means that itcannot always help the driver to steerand keep the vehicle within the lane.
In vehicles equipped with Sensus Navigation
*, the function is able to use
information from map data, which could cause variations in performance.
Pilot Assist will be switched off if thespeed-dependent power steeringwheel resistance is working at reducedpower, e.g. during cooling due to over-heating.WARNING
Pilot Assist should only be used if there are clear lane lines painted on each side of thelane. All other use will increase the risk ofcontact with nearby obstacles that cannotbe detected by the functions.
WARNING
This is not a collision avoidance sys- tem. The driver is always responsibleand must intervene if the system failsto detect a vehicle ahead.
The function does not brake for peopleor animals and does not brake for smallvehicles, such as bikes and motorcy-cles. Similarly, it does not brake for lowtrailers, oncoming, slow-moving or sta-tionary vehicles and objects.
Do not use the function in demandingsituations, such as in city traffic, atintersections, on slippery surfaces,with a lot of water or slush on the road,in heavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
The driver can always correct or adjust steer-ing assistance provided by Pilot Assist by turn-ing the steering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be drivenon flat roads. The function may not be able tomaintain the correct time interval to the vehi-cle ahead when driving down steep hills. Thedriver should be extra attentive and preparedto apply the brakes. Do not use Pilot Assist if the vehicle is carrying a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
Other limitationsThe Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

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.

Auto-hold braking with driver support
The driver support functions Adaptive Cruise Control * and Pilot Assist * have a special brake
function in slow traffic and while stationary.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stopped at a traffic light, driving will resumeautomatically if the vehicle is stopped for lessthan approx. 3 seconds. If it takes more than 3seconds for the vehicle ahead to begin movingagain, the driver support function will go intostandby mode and the auto-hold brake func-tion will activate.
–The function can be reactivated by:
Pressing the
button on the steer-
ing wheel keypad.
Pressing the accelerator pedal.
> The function will resume following the vehicle ahead if it begins to move within approx. 6 seconds.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.

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.
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.

Passing assistance Passing assistance can assist the driver when passing other vehicles. The function can be used with Adaptive Cruise Control * or Pilot
Assist *.
How passing assistance worksWhen Adaptive Cruise Control or Pilot Assist is following another vehicle and you indicatethat you intend to pass that vehicle by using the turn signal 51
, the system will begin accel-
erating toward the vehicle ahead before your
vehicle has moved into the passing lane. The function will then delay a speed reduction to avoid early braking as your vehicleapproaches a slower-moving vehicle. The function remains active until your vehicle has passed the other vehicle.
WARNING
Please note that this function can be acti- vated in more situations than just passinganother vehicle, such as when a directionindicator is used to indicate a lane changeor before exiting to another road – the vehi-cle will then briefly accelerate.
