Rear Collision Warning
The Rear Collision Warning (RCW) function canhelp the driver avoid rear-end collisions fromvehicles approaching from behind.
RCW is automatically activated each time theengine is started.
RCW can warn the driver of a potential collisionwith vehicles approaching from behind by rapidlyflashing the turn signals.
If, at a speed below 30 km/h (20 mph), the RCWfunction detects that the car is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seatbelts and activate the WhiplashProtection System safety system.
Immediately before a collision from behind, RCWmay also activate the foot brake in order toreduce the forward acceleration of the car duringthe collision. However, the brakes will only beapplied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

Rear Collision Warning limitations
In some situations, it may be difficult for RCW towarn the driver of a collision risk.
This may be the case if:
the vehicle approaching from the rear isdetected at a late stage
the vehicle approaching from the rearchanges lanes at a late stage
the vehicle approaching from the rear is mov-ing at a speed above 80 km/h (50 mph)
a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - theRCW function will then be automaticallydeactivated.
NOTE
In certain markets RCW does not warn withthe direction indicators due to local trafficregulations – in such cases, that part of thefunction is deactivated.
NOTE
The warning with direction indicators for RearCollision Warning is deactivated if the colli-sion warning distance in the City Safety func-tion is set to the lowest level "Late".
The seat belt tensioning and braking func-tions remain active.

BLIS limitations
BLIS77 functionality may be reduced in certainsituations.
Keep the marked area clean (on both the left and rightsides of the vehicle)78.
Examples of limitations:
Dirt, ice and snow covering the sensors mayreduce functionality and prevent the systemfrom providing warnings.
The BLIS function is automatically deacti-vated if a trailer, bicycle holder or similar isconnected to the vehicle's electrical system.
For BLIS to function optimally, bicycle hold-ers, luggage racks or similar should not bemounted on the vehicle's towbar.
WARNING
BLIS does not work in sharp curves.
BLIS does not work when the vehicle isbeing reversed.

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)87.
The CTA sensors are located on the inside ofeach of the rear fenders/bumpers and are also
used by the BLIS88 and Rear Collision Warningfunctions.
CAUTION
Repair of BLIS and CTA components orrepainting of the bumper may only be per-formed by a workshop – an authorized Volvoworkshop is recommended.

For more information on Speed Warnings in con-junction with speed cameras, also see “RoadSign Information with Speed Warning and Set-tings” and “Road Sign Information limitations”.
NOTE
For an audible alert to be provided if thespeed is exceeded, the Speed LimitWarning function must be activated andthe Road Sign Audio Warning sub-function must be On. Audible alerts areprovided if the vehicle's speed exceedsthe speed displayed by RSI in the instru-ment panel.
It is possible to receive an audible alertfor speed cameras regardless of the vehi-cle's speed, whether or not the speedlimit is exceeded, and even if the RoadSign Audio Warning function is deacti-vated: See heading "Speed camerawarning On/Off" in section "Road SignInformation with Speed Warning and set-tings" and select Speed Camera AudioWarning there.
Information about speed cameras on thenavigation map is not available for allmarkets/areas.

Road Sign Information (RSI100) functionality maybe reduced in certain situations.
RSI could have reduced functionality due to e.g.:
faded road signs
signs located in a curve in the road
twisted or damaged signs
signs positioned high above the road
fully/partially obstructed or poorly positionedsigns
signs partially or fully covered by frost, snowand/or dirt
digital road maps101 that are outdated, incor-
rect or do not contain speed information102.
NOTE
Certain types of bike carriers that are con-nected to the trailer socket may be interpre-ted as a connected trailer by the RSI function.In such cases, the instrument panel may indi-cate incorrect speed information.

Park Assist front, rear and sides
Park Assist has different parameters dependingon which part of the vehicle is approaching anobstacle.
Front camera
Continuous tone warning signal when the obstacle isless than approx. 30 cm (1 ft) from the vehicle 111.
Park Assist's front sensors are automatically acti-vated when the engine is started. They are activeat speeds below 10 km/h (6 mph).
The distance monitored extends approx. 80 cm(2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivatedwhen the parking brake is applied or when Pis selected on vehicles with automatic trans-mission.
CAUTION
When installing auxiliary lights: Make surethese do not obscure the sensors – the auxili-ary lights could be perceived as an obstacle.
Back
Continuous tone warning signal when the obstacle isless than approx. 30 cm (1 ft) from the vehicle 111
The rear sensors will be activated if the vehiclebegins rolling backward or if reverse gear isengaged.
The distance monitored extendsapprox. 1.5 meters (5 ft) behind the vehicle.
The Parking Assist system's rear sensors will beautomatically deactivated if the vehicle is backingup with a trailer connected to the vehicle's elec-trical system.
NOTE
When reversing with e.g. a trailer or bike car-rier on the trailer hitch – without Volvo originaltrailer cables – the Parking Assist system mayhave to be turned off manually to prevent thesensors from reacting to these.

Park Assist limitations
Park Assist may not be able to detect all condi-tions in all situations and functionality may there-fore be limited in certain cases.
The driver should be aware of the following limi-tations for Park Assist:
WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.
CAUTION
Objects such as chains, thin and glossy polesor low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected.
The sensors cannot detect high objects, suchas protruding ramps.
In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.
CAUTION
In some circumstances, the Park Assist Sys-tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with.
Examples of such sources are horns, wet tireson asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with thevehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.
