become the set speed assuming that the accel- erator pedal is still depressed when the button ispressed. A temporary increase in speed, such as when passing another vehicle, does not affect thespeed set for Pilot Assist. The vehicle will returnto the set speed when the accelerator pedal isreleased. Pilot Assist can follow another vehicle from a standstill up to a speed of approx. 125 mph(200 km/h). Always observe posted speed limits. The lowest speed that can be set/stored for Pilot Assist is 20 mph (30 km/h). However, PilotAssist can monitor and react to the speed of thevehicle ahead down to a standstill. The highest speed that can be set/stored is approx. 125 mph (200 km/h). Always observeposted speed limits.

Setting a Pilot Assist time interval
Different time intervals to the vehicle ahead can be selected and are shown in the instrumentpanel as 1–5 horizontal bars.
Changing the time intervalThe greater the number of bars, the longer the time interval.One bar between the vehiclesrepresents a time interval ofapproximately 1 second; 5 barsis approximately 3 seconds.
NOTE
When the graphic in the instrument panel shows a vehicle and a steering wheel, PilotAssist is following a vehicle ahead using theset time interval. If only a steering wheel is displayed, there is no vehicle ahead within a reasonable dis-tance.

Time interval controls
Press to reduce the time interval to the vehi- cle ahead
Press to increase the time interval to the vehicle ahead
Distance indicator
In order to follow the vehicle ahead as smoothly as possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
• If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

–The driver will then have to reactivate Pilot Assist in one of the following ways:
• Press the
button on the left-side
steering wheel keypad
• Press the accelerator pedal
> Pilot Assist will resume following the vehi- cle ahead (target vehicle) if it begins to move within approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle at a stand- still for up to 5 minutes, after which the park-ing brake will be set and Pilot Assist will gointo standby mode. The parking brake has to be released before Pilot Assist can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivated when the vehicle is at a standstill and Pilot Assistwill go into standby mode. This means that the brakes will be released and the vehicle can begin to roll. The driver must actively apply the brakes to keep the vehicle at a standstill. This can occur in the following situations: • the driver presses the brake pedal
• the parking brake is set •
the gear selector is moved to the
P, N or R
positions
• the driver puts Pilot Assist in standby mode
Automatically setting the parking brakeIn certain situations, the parking brake is set automatically to help keep the vehicle at a stand-still. This occurs if Pilot Assist keeps the vehicle at a standstill with the brakes and:
• the driver unbuckles the seat belt or opensthe door
• Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
• the engine is turned off
• the brakes overheat

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 driving conditions 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 Pilot Assist 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 Pilot Assist 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.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

Radar sensor limitations
The radar sensor used by several of the driver support systems has certain limitations, whichalso affect the systems using it.
Obstructions
The marked area must not be obstructed in any way. This area of the windshield should always be kept clean
The radar sensor is located at the upper, center section of the windshield along with the camera.
WARNING
Never place any objects, decals, electronic toll devices, window tinting films etc., on the wind-shield in front of or around the camera/radarsensor. This could reduce or block these com-ponents' functions, and could cause one ormore of the systems that utilize them to stopfunctioning. This can also result in certain functions being reduced or disabled, or they may respondincorrectly. If this symbol and the message
Windscreen Sensors blockedappear in the instrument panel, this indicates that the camera and/or radar
sensor cannot detect other vehicles ahead.
The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
Cause Action
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow reduces the camera/radar sensor's range of visibility. No action. The driver should be extra alert in conditions of this type.
Water or snow on the surface of the road swirl up and block radar signals or the camera'sview. No action. The driver should be extra alert in conditions of thistype.
There is dirt between the inside of the windshield and the camera/radar sensor. Have the area of the windshield cleaned by a trained and quali- fied Volvo service technician.

• This can also result in certain functionsbeing reduced or disabled, or they mayrespond incorrectly.
To help avoid the risk of incorrect, reduced ordisabled functionality for driver support sys-tems using the camera or radar sensors:
• Volvo recommends that cracks, scratchesor stone chips on the windshield in front of the camera/radar sensor should
not
be repaired; in such cases, the entire windshield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield isused, this may cause City Safety to func-tion improperly or not at all.
• Volvo recommends the use of only Genu-ine Volvo Replacement Windshields.
• When replacing windshield wipers, use the same type or ones approved by Volvo.
After the windshield has been replaced, thecamera/radar sensor will have to be recalibra-ted by a trained and qualified Volvo servicetechnician to help ensure proper function ofall of the vehicle's camera-/radar-based sys-tems.
MaintenanceIn order for camera and radar sensor to function properly, the area of the windshield must be keptfree of dirt, ice, snow, etc. and should be washedregularly with a suitable car washing detergent.
NOTE
Dirt, ice and/or snow covering the camera and radar sensors reduce functionality andmay disable the vehicle's camera-/radar-based systems. This can also result in certain functions being reduced or disabled, or they may respond incorrectly.
