Opening/closing the tailgate with foot movement *
To facilitate the operation of the tailgate when your hands are occupied, it can be opened/closed by means of a forward kicking motionunder the rear bumper.
The sensor is positioned to the left of centre in the bumper 13
.
One of the car's remote control keys must be within range 14
behind the car in order for open-
ing/closing to be possible. This also applies to an already unlocked car in order to avoid accidentalopening e.g. in a car wash.
Operation
Kicking motion within the detector's valid activation area.
Opening/closing
NOTE
The foot-operated tailgate function is availa- ble in two versions:
• Opening and closing with foot movement
• Only unlocking with foot movement (liftup the tailgate manually to open it)
Note that the function for opening and clos-ing with foot movement requires the "Power operated tailgate" * option.
–Make one slow, forward kicking motion
under the left part of the rear bumper. Then take a step back. The bumper must not betouched.
> A short acoustic signal sounds when opening/closing is activated - the tailgate is opened/closed. If the tailgate is on open position then it is always closed on activation via foot move-ment.
The tailgate can also be closed via the instrumentpanel's button, the remote control key or the but- ton(s) 15
under the tailgate. For more information,
see the section "Power operated tailgate". If several kicking motions take place without an approved remote control key being locatedbehind the car, opening will not be possible untilafter a certain delay. Do not leave your foot positioned under the car during the kicking motion. This could cause acti-vation to fail.
Cancel opening/closing
–Make one slow forward kicking motion when
opening/closing is in progress in order to stop the movement of the tailgate.
The remote control key does not have to be inthe vicinity of the car to cancel opening/closing.
13 If the car is equipped with skid plate/diffuser * then the detector is positioned out towards the left-hand corner of the bumper.
14 See the section "Remote control key range" for more information.
15 Only applies to a car equipped with keyless locking/entry (Passive Entry) *.

Alarm
*
The alarm alerts e.g. in the event of a break-in in the car.
When armed, the alarm is triggered if:
• a door, the bonnet or the tailgate is opened 18
• a movement is detected in the passenger compartment (if fitted with a movement detector
*)
• the car is raised or towed away (if fitted witha tilt detector
*)
• the starter battery's cable is disconnected or
• the siren is disconnected.
If there is a fault in the alarm system, the driver display shows the symbol and the message

failure Service required. In which
case, contact a workshop - an authorised Volvo workshop is recommended.
NOTE
Do not attempt to repair or alter components in the alarm system yourself. Any suchattempts may affect the terms of the insur-ance.
NOTE
The movement sensors trigger an alarm in the event of movement in the passengercompartment - air currents are also regis-tered. For this reason the alarm is triggered ifthe car is left with a window or the panoramic roof * open or if the passenger compartment
heater is used. To avoid this: Close the window/panoramic roof when leaving the car. If the car's inte-grated parking heater (or a portable electricheater) shall be used - direct the airflow fromthe air vents so that they are not pointingupwards into the passenger compartment.Alternatively, reduced alarm level can be used- see the section further down in this article.
Arming the alarmLock and arm the car alarm as follows:
• press the remote control key's lock button
• touch in the marked area on the outside of the door handle 19
or
• push on the tailgate's rubberised pressureplate 19
.
If the car is equipped with a power-operated tail- gate, the button on the underside of the tailgatecan also be used to lock the car and arm the caralarm.

Limitations of Distance Warning *
The Distance warning (Distance Alert) function may have limitations in certain situations.
NOTE
Strong sunlight, reflections or strong varia- tions in light intensity, as well as wearing sun-glasses, could mean that the warning light inthe windscreen cannot be seen. Poor weather or winding roads could affect the radar unit's capacity to detect vehicles infront. The size of other vehicles could also affect detection capacity, e.g. motorcycles. Thiscould mean that the warning lamp illuminatesat a shorter distance than the setting or thatthe warning is temporarily absent. Extremely high speeds can also cause the lamp to illuminate at a shorter distance thanthat set due to limitations in sensor range.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Adaptive cruise control
*
The adaptive cruise control (Adaptive Cruise Control - ACC) helps the driver to maintain aneven speed combined with a pre-selected timeinterval to the vehicle ahead.
An adaptive cruise control provides a more relax- ing driving experience on long journeys on motor-ways and long straight main roads in smooth traf-fic flows.
The camera and radar unit measures the distance to the vehicle ahead 5
.
The driver selects the desired speed and a time interval to the vehicle ahead. If the camera andradar unit detects a slower vehicle in front of thecar, the speed is adapted automatically via thepreset time interval to the vehicle. When the road

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• 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 edges orstrong 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 impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Limitations of the radar unit The radar unit has certain limitations - which in turn also limits those functions that use the unit.
Blocked unit
The marked area must be kept free from stickers, objects, shade film, etc.12
.
The radar unit is placed inside the upper section of the windscreen together with the car's cameraunit.
IMPORTANT
Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera and radar-depend-ent functions. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response.
If the driver display shows this symbol with the message Windscreen
sensor Sensor blocked, see
Owner's manual, it means that the
camera and radar unit cannot detect other vehi- cles in front of the car.
The following table presents examples of possi- ble causes for a message being shown, alongwith the appropriate action:
Cause Action
The windscreen surface in front of the camera and radar unit is dirty or cov- ered with ice or snow. Clean dirt, ice and snow from the windscreen surface in front of the cameraand radar unit.
Thick fog and heavy rain or snow block the radar signals or the cameraview. No action. Sometimes the unit does not work during heavy rain or snowfall.

Limitations of the camera unit
The camera unit has certain limitations - which in turn also limits those functions that use the unit.
Impaired visionThe camera has limitations similar to the human eye, i.e. it can "see" worse in for example intensesnowfall or rain, dense fog, heavy dust stormsand snow flurries. Under such conditions, thefunctions of camera-dependent systems could besignificantly reduced or temporarily disengaged. Strong oncoming light, reflections in the carriage- way, snow or ice on the road surface, dirty roadsurfaces or unclear lane markings can also sig-nificantly reduce camera function when it is usedto scan the carriageway to detect pedestrians,cyclists, large animals and other vehicles.
Blocked unit
The marked area must be kept free from stickers, objects, shade film, etc. 13
.
The camera unit is placed inside the upper sec- tion of the windscreen together with the car'sradar unit.
IMPORTANT
Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera and radar-depend-ent functions. This may mean that functions are reduced, deactivated completely or give incorrect func-tion response.

has the opportunity to avoid a collision via a steering manoeuvre. However, if City Safety anticipates that an evasive manoeuvre is not possible due to traffic in anadjacent lane, the function can assist the driverby automatically starting to brake at an earlierstage.
WARNING
City Safety's ability to anticipate a certain sit- uation is an aid, and does not work in all driv-ing situations or traffic, weather and road con-ditions. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safelyand that applicable laws and road traffic regu-lations are followed.

Limitations of City Safety
The City Safety function may have limitations in certain situations.
Surroundings
Low objects
Low-hanging objects, e.g. a flag/pennant for pro- jecting load, or accessories such as auxiliarylamps and bull bars that are higher than the bon-net limit the function.
Skidding
On slippery road surfaces the braking distance is extended, which may reduce the capacity of CitySafety to avoid a collision. In such situations, theanti-lock brakes and the stability control ESC willgive the best possible braking force with main-tained stability.
Oncoming light
The visual warning signal in the windscreen may be difficult to notice in the event of strong sun-light, reflections, when sunglasses are beingworn or if the driver is not looking straight ahead.
Heat
In the event of high passenger compartment temperature caused by e.g. strong sunlight, thevisual warning signal in the windscreen may betemporarily disengaged.
The camera and radar unit's field of view
The camera's field of vision is limited, which is why pedestrians, large animals, cyclists and vehi- cles in some situations cannot be detected, orthey are detected later than anticipated. Dirty vehicles may be detected later than others and if it is dark, motorcycles may be detected lateor not at all. If a text message in the driver display indicates that the camera and radar unit is obstructed, CitySafety may be unable to detect pedestrians, largeanimals, cyclists, vehicles or road lines ahead ofthe car. This means that the functionality of CitySafety may be reduced. However, an error message is not shown in all situations where the windscreen sensors areobstructed. The driver must therefore take care tokeep the area of windscreen in front of the cam-era and radar unit clear.
IMPORTANT
Maintenance and replacement of City Safety components must only be performed by aworkshop - an authorised Volvo workshop isrecommended.
Driver intervention
Reversing
When your own car is reversing, City Safety is temporarily deactivated.
