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.

standby mode
Pilot Assist can be deactivated and put in standby mode. This may happen automati-cally or be due to driver intervention.
Standby mode means that the function is selected in the instrument panel but not acti-vated. In standby mode, Pilot Assist will notregulate the speed or distance to the vehicleahead or provide steering assistance.
Standby mode due to action by the
driver
Pilot Assist will be deactivated and put instandby mode if any of the following occurs:
The brakes are applied.
The gear selector is moved to
N.
A turn signal is used for more than1 minute.
The vehicle is driven faster than the setspeed for more than 1 minute.
Automatic standby modePilot Assist is dependent on other systems, such as Electronic Stability Control (ESC 39
). If
any of these other systems stops working, Pilot Assist will be automatically deactivated.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a mes-sage on the instrument panel.
The driver must then regulate vehicle speed, apply the brakes if necessary,and maintain a safe distance to othervehicles.
Adaptive Cruise Control may go into standbymode if, e.g.: the driver opens the door.
the brake temperature is high.
the driver's hands are not on the steering wheel.
the parking brake is applied.
the engine speed (rpm) is too low/high.
the driver unbuckles the seat belt.
one or more of the wheels lose traction.
the camera/radar sensor is covered by snow or heavy rain (the camera lens/radarwaves are blocked).
your vehicle's speed goes under 5 km/h(3 mph) and Pilot Assist cannot determineif the vehicle ahead is stationary or if it isanother object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns sothat Pilot Assist no longer has a vehicle tofollow.

Temporarily deactivating steering assistance with Pilot Assist *40
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-

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 47
, 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.
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.

Rear Collision Warning *59
The Rear Collision Warning 60
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
The function can alert drivers of following vehi- cles of the risk of a collision by rapidly flashingthe turn signals. If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.

The BLIS 62
function is designed to help pro-
vide assistance in heavy traffic with several lanes moving in the same direction by helpingthe driver to detect the presence of vehiclesin the "blind spot" area behind and to the sideof the vehicle.
Location of BLIS indicator light.
BLIS is a driver support system designed to alert the driver of:
vehicles in your "blind spot"
vehicles approaching rapidly in adjacentlanes.
BLIS overview
Blind spot zone
Rapidly approaching vehicle zone.
The system is designed to react to:
vehicles passing your vehicle
vehicles that are rapidly approaching your vehicle from behind.
When BLIS detects a vehicle in zone 1 or arapidly approaching vehicle in zone 2, an indi-cator light will illuminate in the relevant rear-view mirror and glow steadily. If the driverthen uses the turn signal on the side in whichthe warning has been given, the indicator lightwill become brighter and begin flashing. BLIS is active when your vehicle is traveling at a speed over 10 km/h (6 mph).

Lane Keeping Aid alerts the driver using vibrations in the steering wheel.
Depending on the settings used, Lane Keep- ing Aid functions in different ways:
Assist enabled: When the vehicle
approaches a lane marker line, the func- tion will actively steer the vehicle back intothe lane using light pressure on the steer-ing wheel.

Warning enabled: If the vehicle is about
to move over a lane marker line, the driver will be alerted by vibrations in the steeringwheel.
There is also an option for activating steeringassistance and alerts at the same time.
NOTE
When the direction indicators/turn signals are activated, the Lane Keeping Aid doesnot provide any warning or intervene withsteering.
