Speed-dependent steering wheel resistance Speed-dependent power steering increases the steering wheel resistance in pace withthe vehicle's speed, which can help give thedriver an enhanced feeling of control and sta-bility.
Steering is stiffer on highways. When parking and at low speeds, it will be easier to movethe steering wheel.
NOTE
In rare situations, the power steering may become too hot andrequire temporary cooling – dur-ing such time the power steering
will work at reduced output and the steer-ing wheel may feel more difficult to move. The message
Power steering Assistance
temporarily reduced will be displayed
along with this symbol in the instrument panel.
While the power steering is working at reduced power, the driver support func-tions and systems with steering assistanceare not available.

vehicles ahead, the vehicle will return to the set speed. If the Curve Speed Assist (CSA)
* function is
activated, it may also affect the vehicle's speed.
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.
Adaptive Cruise Control regulates speed byaccelerating and braking. It is normal for thebrakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts toregulate speed smoothly. The driver mustapply the brakes in situations requiring imme-diate braking. For example, when there aregreat differences in speed between vehicles orif the vehicle ahead brakes suddenly. Due tolimitations in the radar sensor, braking mayoccur unexpectedly or not at all. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintaina time interval to that vehicle set by the driver.If the radar sensor does not detect a vehicleahead, it will instead maintain the speed setby the driver. This will also happen if the speedof the vehicle ahead exceeds the set speed foryour vehicle.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.

Pilot Assist *38
Pilot Assist can help the driver keep the vehi- cle in the current traffic lane by providingsteering assistance and maintaining an evenspeed and a set time interval to the vehicleahead.
How Pilot Assist worksThe Pilot Assist function is primarily intended for use on highways and other major roadswhere it can help provide a more comfortableand relaxing driving experience.
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings.
Camera and radar sensor
Distance monitor
Lane marker line monitors The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors thedistance to the vehicle ahead and the trafficlane's side markers using the camera andradar sensor. The system maintains the settime interval to the vehicle ahead by automati-cally adjusting your vehicle's speed and keepsyour vehicle in its lane by providing steeringassistance. If the Curve Speed Assist (CSA)
* function is
activated, it may also affect the vehicle's speed. Pilot Assist's steering assistance is based on monitoring the direction of the vehicle aheadand the traffic lane's side marker lines. Thedriver can override Pilot Assist's steering rec-ommendations at any time and steer inanother direction, e.g. to change lanes or avoidobstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist isunable for some other reason to clearly inter-pret the lane, Pilot Assist will temporarilydeactivate steering assistance until it can onceagain interpret the lane markings. However,the speed and distance warnings will remainactive. The driver will be alerted by slightvibrations in the steering wheel that the func-tion has been temporarily deactivated.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
The color of the steering wheel symbol indicates thecurrent status of steeringassistance: • GREEN indicates that steering assistance is active
• GRAY (as shown in illustration) indicates thatsteering assistance is deactivated.
38 Depending on market, this function can be either standard or optional.

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.

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-
