Road Sign Information (RSI 86
) functionality
may be reduced in certain situations.
The function 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 posi- tioned signs
signs partially or fully covered by frost,snow and/or dirt
digital road maps 87
that are outdated,
incorrect or do not contain speed informa- tion 88
.
NOTE
In certain markets, the Road Sign Informa- tion * function is only available in combina-
tion with Sensus Navigation *.
NOTE
Certain types of bike carriers that are con- nected to the trailer socket may be inter-preted as a connected trailer by the RSIfunction. In such cases, the instrumentpanel may indicate incorrect speed infor-mation.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning 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 be affected despite the driver's fatigue – when using the Pilot Assist
* function –
resulting in the driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest signof fatigue, regardless of whether the func-tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Lane Keeping Aid
Lane Keeping Aid (LKA 89
) is designed to
actively steer the vehicle on freeways, high- ways and other major roads to help the driverreduce the risk of the vehicle unintentionallyveering out of the lane.
Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavail- able and go into standby mode. The functionwill become available again when the roadbecomes sufficiently wide.
A camera monitors the road/traffic lane's marker lines.
Lane Keeping Aid steers the vehicle back into its lane.

Lane Keeping Aid limitations
In certain demanding driving conditions, Lane Keeping Aid (LKA 92
) may not be able to prop-
erly assist the driver. In these situations, it is recommended that the function be deacti-vated.
Examples of such situations include:
road work
winter driving conditions
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's side markings
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
The function cannot detect barriers, railings orsimilar obstacles at the side of the lane.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Steering assistance during collision risks limitations
The function may have limited functionality in certain situations and not intervene, e.g.:
for smaller vehicles such as motorcycles
if more than half of your vehicle has moved into the adjacent lane
on roads/lanes with indistinct or no sidelane markings
outside the speed range 60-140 km/h(37-87 mph)
when speed-dependent power steeringwheel resistance is working at reducedpower – e.g. during cooling due to over-heating.
Functionality may also be reduced in other sit-uations, such as: road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the function may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Park Assist *
The Park Assist function can help the driver when maneuvering in tight spaces by indicat-ing distances to obstacles using audible sig-nals and graphics in the center display.
Display view showing obstacle zones and sensor sectors.
The center display shows an overview of the vehicle in relation to objects that have beendetected. The marked sector indicates where the obsta- cle is located. The closer the vehicle symbol isto a marked sector forward/rearward, thecloser the detected obstacle is to your vehicle. The side sectors change color as the distance between the vehicle and an object decreases. The audible signals will also speed up the closer the obstacle is to the vehicle. The vol- ume of the audio system will be automaticallylowered. Audible signals for obstacles in front and to the sides of the vehicle are active when thevehicle is moving but will cease after the vehi-cle has been stationary for approx. 2 seconds.Audible signals for obstacles behind the vehi-cle will remain active even when the vehicle isstationary. If a detected obstacle is within approx. 30 cm (1 ft) from the front or rear of the vehicle, thetone will become constant and the active sen-sor's field closest to the vehicle symbol will befilled in. At distances within approx. 25 cm (0.8 ft) from an obstacle to the sides of the vehicle, anrapid pulsing signal will be given and theactive sector fields will change color fromORANGE to RED. The volume of the Park Assist audible signals can be adjusted while the signal is being givenusing the
>II knob or in the center display's
Top view under
Settings.
NOTE
Besides in the sector closest to the vehicle symbol, audible warnings are only providedfor objects located directly in the vehicle'spath.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

Park Assist front, rear and sides *
Park Assist behaves differently depending on which part of the vehicle is approaching anobstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored extends approx. 1.5 meters (5 ft) behind the vehicle. The Park Assist system's rear sensors will be automatically deactivated if the vehicle isbacking up with a trailer connected to thevehicle's electrical system.
NOTE
When reversing with e.g. a trailer or bike carrier on the trailer hitch – without Volvooriginal trailer cables – the Parking Assistsystem may have to be turned off manuallyto prevent the sensors from reacting tothese.
