Recommended maintenance forBLIS
For optimal performance, it is important tokeep the areas in front of the sensors clean.
Do not attach any objects, tape or decals tothe surface of the sensors.
Keep the marked area clean (on both the left and rightsides of the vehicle)75.
The BLIS sensors are located on the inside ofeach of the rear fenders/bumpers and are alsoused by the Cross Traffic Alert (CTA) and RearCollision Warning functions.

CAUTION
Repair of BLIS and CTA components orrepainting of the bumper may only be per-formed by a workshop – an authorized Volvoworkshop is recommended.

Cross Traffic Alert*
CTA77 is a supplementary driver support system
to BLIS78 that is intended to help the driverdetect vehicles crossing behind the vehiclewhile backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross-ing from the side, e.g. when backing out of aparking space.
CTA is primarily designed to detect vehicles, butin certain cases can also detect pedestrians orsmaller objects such as bicycles.
CTA is only active when the vehicle is movingbackward or if reverse gear is engaged.
If CTA detects that something is approachingyour vehicle from the side:
an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
an icon will illuminate in the PAS79 graphicon the screen.
an icon will appear in the Park Assist Cam-era's Top view.
Illuminated CTA icon in the PAS graphic80 on thescreen.

WARNING
The Cross Traffic Alert function is supple-mentary driver support intended to facili-tate driving and make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
The responsibility for reversing the vehiclesafely and using good judgment alwaysrests with the driver.
Cross Traffic Alert is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.

Examples of further limitations
Dirt, ice and snow covering the sensors mayreduce functionality and prevent the systemfrom providing warnings. For additional infor-mation, see the section "Recommendedmaintenance for Cross Traffic Alert".
CTA is automatically deactivated if a trailer,bicycle holder or similar is connected to thevehicle's electrical system.
For CTA to function optimally, bicycle hold-ers, luggage racks or similar should not bemounted on the vehicle's towbar.

The Rest Stop Guidance function can beswitched on or off.
In vehicles equipped with Sensus Navigation*, thedriver can activate a guide that can automaticallysuggest a suitable rest stop if the DAC warningis given.
To select Rest Stop Guidance:
1.Tap Settings in the center display's Topview.
2.Select My CarIntelliSafeDriver AlertControl.
3.Select/deselect Rest Stop Guidance toactivate/deactivate the function.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may bereduced in certain situations.
In certain situations, the system may provide awarning even if it has not detected a change indriving behavior, e.g.:
in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not beaffected despite the driver's fatigue – whenusing the Pilot Assist function – resulting inthe driver not getting a warning from DAC.
It is therefore very important to always stopand take a break at the slightest sign of fati-gue, regardless of whether the DAC functionhas issued a warning or not.

NOTE
The function uses the vehicle's camera unit,which has some general limitations – see thesection "Camera unit limitations".

Lane Keeping Aid
Lane Keeping Aid (LKA99) is designed toactively steer the vehicle on freeways, highwaysand other major roads to help the driver reducethe risk of the vehicle unintentionally veering outof the lane.
Lake Keeping Assistance steers the vehicle backinto the lane and/or alerts the driver using vibra-tions in the steering wheel.
Lane Keeping Aid is active at speeds between65-200 km/h (40-125 mph) on roads withclearly visible traffic lane marker lines.
On narrow roads, the function may be unavailableand go into standby mode. The function willbecome available again when the road becomessufficiently wide.
A camera monitors the road/traffic lane's marker lines.

HYBRID INFORMATION
408
General information about TwinEngine
Twin Engine vehicles are driven just like anyother vehicle, but certain functions differ from avehicle powered exclusively by gasoline. Theelectric motor powers the vehicle primarily at lowspeeds; the gasoline engine is used at higherspeeds or during more active driving.
The instrument panel displays Twin Engine-spe-cific information - charging information, selecteddrive mode, distance to discharged battery andhybrid battery charge level.
Different drive modes can be selected while driv-ing, e.g. electric power only or, if more power isneeded, a combination of electric and gasolinepower. The vehicle calculates the optimal combi-nation of driveability, driving experience, environ-mental impact and fuel economy for the selecteddrive mode.
In order to function optimally, the hybrid battery(and its electrical drive systems) and the gasolineengine (and its drive systems) must be at thecorrect operating temperature. Battery capacitycan be considerably reduced if the battery is toocold or too hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before driving to help reduce both wear andenergy consumption. It also helps increase thehybrid battery's range.
The hybrid battery which powers the electricmotor is recharged using the charging cable. It
can also be recharged during light braking andthrough engine braking in gear position B. Thecombustion engine can also help recharge thehybrid battery.

Important
No electrical current
Keep in mind that if there is no electrical currentto the vehicle, i.e. the ignition is switched off orthe start battery is discharged, certain functionssuch as brakes, power steering, etc. will not work.

WARNING
If the vehicle does not have electrical currentand both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop the vehicle.

Towing not permitted
Never tow a Twin Engine vehicle behind anothervehicle, as this could damage the electric motor.

Exterior engine noise
WARNING
Please be aware that there is no sound fromthe engine when the vehicle is being poweredby the electric motor and it may be difficult todetect by children, pedestrians, cyclists andanimals. This is especially true at low speeds.
High-voltage electrical current
WARNING
A number of electrical components in TwinEngine Plug-in Hybrid vehicles use high-volt-age current and can be extremely dangerousif handled incorrectly. These components andany orange wiring in the vehicle may only behandled by trained and qualified Volvo servicetechnicians.
Do not touch anything that is not clearly descri-bed in this Owner's Manual.
