Adaptive Cruise Control – introductionACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead. It is primarilyintended for use on long straight roads in steadytraffic, such as on highways and other mainroads.
When the driver has set the desired speed and the time interval to the vehicle ahead, ACC func-tions as follows:
• If there are no other vehicles in the laneahead of you, your vehicle will travel at theset speed.
• If ACC's radar sensor detects a slower mov-ing vehicle in the lane ahead, the system willadapt your vehicle's speed to help maintainthe set time interval to the vehicle ahead.When there are no longer slower movingvehicles ahead, your vehicle will accelerate toresume the set speed.
If ACC is switched off completely or in standbymode and your vehicle comes too close toanother vehicle ahead, the driver will be warnedby the Distance Alert system (see Distance Alert– introduction (p. 191)).
WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic, weather androad conditions. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingthis feature.
• This system is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance and speedand must intervene if Adaptive CruiseControl does not maintain a suitablespeed or suitable distance to the vehicleahead.
• Maintenance of ACC components mayonly be performed by a trained and quali-fied Volvo technician.

Lane Keeping Aid (LKA) – operation
LKA is active at speeds above 40 mph (65 km/h) on highways or other major roads with clearlymarked side/lane marker and center lines. Onnarrow roads where the distance between side/lane marker lines is less than approximately8.5 feet ( 2.6 meters), LKA will be temporarilydeactivated.
LKA monitors and follows the marker lines (the red lines in the illustration)
•White
side marker lines: the function is
active and "sees" one or both of the road's side marker lines.
• Gray
side marker lines: the function is active
but cannot "see" one or both of the road'sside marker lines.
LKA intervening on the right side (the red line)
When LKA is working actively, this is indicated by:
• Red
side marker line: the line being crossed.
On/Off
LKA can be switched on or off by pressing the button on the center console. A light in the but-ton illuminates when the function is on. Depending on the number of optional featuresinstalled in the vehicle, there may not be spacefor the On/Off button on the center console. Ifthis is the case, LKA can be switched on or off in the
MY CAR menu system.
The following LKA-related settings can also be made in MY CAR , under

Steering assist
LKA attempts to keep the vehicle within the lane's side marker lines.
LKA provides steering assistance
If the vehicle approaches one of the lane's side marker lines and the turn signals are not
being used , LKA will attempt to steer the vehicle
back into the lane.
Vibration warnings
LKA provides vibrations in the steering wheel and steer- ing assistance 11
.
If the vehicle crosses a marker line, LKA provides a warning in the form of vibrations in the steeringwheel. This occurs even if the steering assistfunction has been deactivated.
Dynamic cornering
LKA does not intervene in sharp left curves
In certain cases, LKA allows the vehicle to cross marker lines without providing a vibration warningor steering assistance, for example, duringdynamic cornering as shown in the illustrationwhere the driver's view of the road and trafficconditions make this possible.

Rear Park Assist Camera (PAC) – limitations
LimitationsEven if a fairly small section of the screen image appears to be obstructed, this may mean that arelatively large area behind the vehicle is hiddenand objects there may not be detected until theyare very near the vehicle.
NOTE
Bicycle carriers or other accessories mounted on the trunk may obstruct the camera's fieldof view.
Keep in mind
• Keep the camera's lens free of dirt, ice and snow. Remove ice and snow carefully toavoid scratching the lens.
• Clean the lens regularly with warm water anda suitable car washing detergent.

BLIS
* – introduction
The Blind Spot Information System (BLIS) is an information system that indicates the presenceof another vehicle moving in the same directionas your vehicle on roads with several lanes.

Indicator light

BLIS and CTA 13
are activated when the engine is
started; this is confirmed when the indicator lights on the front door panels flash once.
NOTE
The door panel indicator light illuminates on the side of the vehicle where the system hasdetected another vehicle. If your vehicle ispassed on both sides at the same time, bothlights will illuminate.
The system helps provide information about:
• Other vehicles in your door mirrors' "blind area"
• Vehicles that are about to pass your vehiclein the left and/or right lanes
• Cross Traffic Alert (CTA) is a supplemen-tary BLIS function
intended to detect vehi-
cles crossing behind your vehicle while youare backing up.

BLIS* – Cross Traffic Alert (CTA)
Cross Traffic Alert (CTA) is a supplementary BLIS 15
function intended to detect vehicles
crossing behind your vehicle while you are back- ing up.
Park assist/CTA button
On vehicles equipped with the optional Park assist system (p. 231), Cross Traffic Alert (CTA)can be deactivated/reactivated by pressing thePark assist button on the center console. TheBLIS indicator lights on the front doors will flashwhen CTA is reactivated by pressing the button.
WARNING
• BLIS and CTA are information systems, NOT warning or safety systems and donot function in all situations.
• BLIS and CTA do not eliminate the needfor you to visually confirm the conditionsaround you, and the need for you to turnyour head and shoulders to make surethat you can safely change lanes or backup.
• As the driver, you have full responsibilityfor changing lanes/backing up in a safemanner.
When does CTA function
How CTA works
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, for example,when backing out of a parking space. It is primarily designed to detect another vehicle but in certain cases may also detect pedestriansor smaller objects such as bicycles. CTA is only activated when the vehicle is backing up and is activated automatically when the gearselector is put in reverse.
• An audible signal indicates that CTA hasdetected something that is approaching fromthe side. The signal will come from either theleft or right audio system speakers, depend-ing on which the side of your vehicle theapproaching vehicle/object has beendetected.
• CTA also provides a warning by illuminatingthe BLIS indicator lights.
• An icon will also illuminate in the Park assistgraphic on the center console display.
LimitationsCTA has limitations in certain situations, forexample, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
